(collectively Williams) owned and operated a North Pole refinery beginning in  1977.  



                                                                                                                           

The refinery  is  on  State-owned land which  Williams  leased.   Williams began  using

                    Williams allowed sulfolane to migrate into the groundwater at the refinery

hundreds   of   gallons   of   solution   with   sulfolane   concentrations   ranging   from   66%   to  



100%.  



                  Sulfolane   was   detected   in   groundwater   at   the   refinery   in  1996   when  



Williams's  lab   manager   found   sulfolane   in   groundwater   samples   in   concentrations  



ranging from 250,000-2,700,000 parts per billion (ppb).   Williams did not report its 1996  



detection   of   sulfolane   in   groundwater   to   the   Alaska   Department   of   Environmental  



Conservation  (DEC)  until  five  years  later  in  October  2001,  when  Williams's  consultant  



Shannon   &   Wilson  prepared   a   report   for   Williams's   2002   Site   Characterization   and  



Corrective  Action  Plan  to  address  earlier  environmental  concerns  about  the  refinery.   By  



2001  sulfolane  was  generally  known  in  the  scientific  community  to  "exhibit[]  low  levels  



of  toxicity,"  but  there  otherwise  was  a  dearth  of  available  information  about  sulfolane,  



and  DEC  did  not  regulate  it  as  a  hazardous  substance.   DEC  advised  Williams  about  this  



uncertainty  regarding sulfolane's toxicity and cautioned  Williams  about  sulfolane's  high  



mobility    in    groundwater.      DEC    instructed   Williams   to  continue    sampling   the  



groundwater  until  it  found  the  contamination  source.   DEC  informed  Williams  it  could  



reduce  sampling  frequency  if  its  data  were  not  changing  and  it  could  not  find  a  source.   



Williams  was  not  able  to  determine  the  specific  source  and  stopped  sampling  altogether  



in  July  2002.  



                  Williams   also  used   aqueous   foams   as  part   of  its   fire  response  practices.   



These  foams  at  the  time  contained  per- and  polyfluoralkyl  substances,  commonly  called  

"PFAS."1   The PFAS in the foams included a wide range of synthetic chemicals; among

describe  a group  of over  5,000 different synthetic chemicals that are used in industrial  

and  commercial  applications  throughout  the  world,  most  commonly  to  repel  water  and

the   chemicals were  perfluorooctanesulfonic   acid   (PFOS)   and  perfluorooctanoic   acid  



            2  

(PFOA).   Testing  of  the  groundwater  and  soil  at  the  refinery  shows  that,  at  the  time  of  



trial,  they  contained  several  PFAS,  including  PFOA  and  PFOS.  



                   On  March   31,  2004  Williams   sold  the  refinery  to  Flint  Hills  Resources,  



LLC  and  Flint  Hills  Resources  Alaska,  LLC  (collectively  Flint  Hills).   The  parties  to  the  



sale signed an Asset Sale and  Purchase Agreement they agreed  would be  governed by  



Texas   law.     It   contained   detailed   provisions   about   the   assumption   or   retention   of  



liabilities   related   to   all   aspects   of   the   refinery's   operations, including   environmental  



liabilities.   The  parties  agreed  to  hold  harmless  and  indemnify  each  other  for  costs  arising  



from  their  respective  retained  liabilities.   Williams  agreed  to  retain  most  environmental  



liabilities  arising  from  its  operations  at  the  refinery,  excepting  specific  matters  listed  on  



a  Disclosure  Schedule.  



                   In   an  effort   to   ensure   more   certainty   about   future   indemnification  



obligations,   the   parties   included   a   limit   on   indemnifiable   damages   with   a   specific  



Environmental  Cap  of  $32  million.   They  further  agreed  that  for  claims  "arising  out  of"

exclusive,  with  certain  exceptions  including  claims  for  equitable  relief.   Williams  agreed  



to  purchase  a  $50  million  environmental  liability  insurance  policy  and  paid  $2.4  million  



in  premiums.  



                   The  Purchase  Agreement  also  specified  that  Flint  Hills  was  responsible  for  



future sulfolane  releases  at  the  refinery beginning April   1, 2004.   DEC informed  Flint  



         2         Because the  ingredients  in  the  foam were proprietary information, the exact  



compounds   contained in the   foams   were   not   known   at   the   time.    An   expert   witness  

testified   at   trial   that,   based   on   safety   information   provided   by   the   manufacturer,   the  

PFAS  presumably  included  PFOA.   Williams  admitted  the  foams  contained  PFAS  and  

PFOS,  but  stated  it  did  not  know  whether  they  contained  PFOA.

Hills  in  October  2004  that  it  considered  sulfolane  a  regulated  contaminant  and  would  be  



adopting  cleanup  standards.  



                  By April   2019   the   sulfolane   in   the   groundwater   had   laterally   travelled,   



creating  a  plume  approximately  two  miles  wide,  three  and  a  half  miles  long,  and  over  



three   hundred   feet   deep,   and   spreading   offsite   from   the   refinery.     The   plume   then  



extended  into  the  City  of  North  Pole's  groundwater,  and  it  is  expected  that  sulfolane  will  



continue  to  flow  from  the  refinery  site.   Flint  Hills  and  the  State  have  taken  a  variety  of  



steps to mitigate damages from the groundwater  sulfolane plume, including providing  



alternative    interim    water,    well-testing,    community    outreach,    and    drafting    site  



characterization   and   corrective   action   plans.     The   most   significant   step   has   been  



expanding  the  City's  piped  water  system.

denied that its sulfolane releases were unlawful; asserted various legal, equitable, and

State and Williams were  responsible parties  under  AS  46.03.822(a),  and Flint  Hills  



                                                                                                                              

counterclaimed  against  the  State  for  contribution  under  AS  46.03.822(j).                                          It  also

                    The  City  of  North  Pole  also  filed  suit  that  year.   Its  case  and  a  case  brought  



by  a  North  Pole  resident  against  Williams  and  Flint  Hills  in  2010  were  consolidated  with  



the  State's  suit.   After  PFAS  contamination  was  discovered  at  the  site,  the  State  and  Flint  



Hills  filed  additional  claims  against  Williams.  



                    In  2016  we  ruled  in  Flint  Hills  Resources  Alaska,  LLC  v.   Williams  Alaska  



Petroleum,  Inc.  (Flint  Hills  I)  that  Flint  Hills's  claims  against  Williams  for  contractual  



indemnification  and  statutory  contribution  under  AS  46.03.822(j)  were  time-barred  with  



                                                                                                                       21  

respect  to  onsite  sulfolane  contamination,  but  not  offsite  sulfolane  contamination.                               We  



also determined  that  because  Flint  Hills's claims against  Williams for declaratory  and  



injunctive  relief  were  "equitable  remedies  .  .  .  identical  to  the  legal  remedies  Flint  Hills  

sought  in  its  statutory  and  contractual  claims,"22  it had not been error for the superior

                    In February 2017 Flint Hills reached a settlement with the State and the

superior court accordingly dismissed with prejudice the State's and Flint Hills's claims

parties  agreed  the  court  would  refer  the  offsite  PFAS  claims  to  DEC  under  the  doctrine  



                                 24  

of  primary  jurisdiction.           Williams  moved  to  defer  onsite  PFAS  issues  to  DEC  under  the  



same  doctrine,  but  the  superior  court  denied  the  motion,  finding  it  was  "primarily  made  



for  purposes  of  delay"  and  would  not  facilitate  the  "orderly  and  reasonable  coordination  



of  the  work  of  agencies  and  courts"  after  "five  years  of  active  litigation."   



                   In June 2019  the superior court deconsolidated the State's and  the City's  



cases  against  Williams.  



                   The  State's  case  against  Williams  proceeded  to  a  bench  trial.   Over  16  days  



each  side  called lay  and  expert  witnesses a   nd  admitted  thousands  of  pages  of  exhibits  



                    25  

into  evidence.         The  court  issued  a  lengthy  memorandum  decision  and  final  judgment,  



concluding  that  sulfolane  is  a  hazardous  substance  and  that  Williams  is  strictly,  jointly,  



and  severally  liable  for  its  sulfolane  release  as  well  as  for  onsite  PFAS  and  oil  releases.   



The court allocated  75% responsibility for  offsite sulfolane costs to  Williams and ordered  



it  to  pay  damages  for  that  portion  of  the  State's  response  and  oversight  costs,  as  well  as  



for  natural  resource  damages  caused by  the  loss  of  the  public's  access  to  groundwater  



due  to  sulfolane  contamination.   The  court  held  Williams  responsible  for  75%  of  future  



State  costs  related  to  the  piped  water  system  and  held  further  that  the  State  could  recover  



from  Williams  that  portion  of  "DEC's  future  oversight  costs."   The  court a   dditionally  



ordered  Williams  to  abide  by  Alaska  statutes  and  DEC  regulations  related  to  monitoring,  



reporting,  and  cleanup  of  offsite  sulfolane  and  onsite  PFAS.   The  court  found  that  Flint  



          24       "Primary  jurisdiction  is  a  judicially  created  prudential  doctrine  that  applies  



'to  claims  properly  cognizable  in  court  [but]  that  contain  some  issue  within  the  special  

competence  of  an  administrative  agency.'  "   Seybert  v.  Alsworth ,  367  P.3d  32,  39  (Alaska

Hills  was  not  responsible  for  PFAS  contamination  at  the  refinery.  



                  The superior  court then turned to Flint  Hills's claims against Williams to  



recover  costs  for  responding  to  the  contamination.   The  court  determined  that  Williams  



had  retained  liability  for  offsite  sulfolane  existing  on  the  date  Flint  Hills  acquired  the  



refinery.    The   court   found   that,   although   Flint   Hills   could   not   recover  its costs   for  



responding   to   the   contamination   through   the   Purchase   Agreement's indemnification  



provisions,  Flint  Hills  could  obtain  statutory  contribution under AS 46.03.822(j).   The  



court  granted  Flint  Hills  recovery  from  Williams  for  its  equitable  share  of  past  offsite  



sulfolane  response  costs,  as  well  as  its  share  of  future  costs  related  to  the  piped  water  



system and other offsite  sulfolane  remediation costs.  The court also ordered Williams  



to   indemnify,   defend,   hold   harmless,   and   reimburse   Flint   Hills   for all   onsite   PFAS- 



related   future   claims   and   costs.    And   the   superior   court   dismissed   all   of   Williams's  



claims  against  the  State  and  Flint  Hills.   



                  Williams  appeals,  claiming the superior  court  erred on various points  of fact  



and  law.

satisfied  all  three  statutory  definitions  of  hazardous  substance  under  AS  46.03.826(5).                             



Williams   argues   that   the   superior   court   misinterpreted  the   law   when   it   found   that  



sulfolane  met  any  of  the  three  statutory  definitions  of  hazardous  substance.   We  disagree,  



and   affirm  the   superior   court's   determination  that   sulfolane   is   a  hazardous   substance  



under  the  Act.  



                   Several   weeks   before   trial,   the   superior   court   issued   a   memorandum  



tentatively  adopting  interpretations of "hazardous substance" used in  AS  46.03.822(a)  



and   defined   in   subsection  .826(5)(A).     It   later   adopted   those   interpretations   in   its  



decision.   The  court  construed  "imminent  and  substantial  danger  to  the  public  health"  to  



mean  "a  reasonable  medical  concern  about  the  public  health  where,  given  the  modifier  



'substantial,'   the   nature   of   the   harm   giving   rise   to   concern   is   serious   and,   given   the  



modifier  'imminent,'  the  threat  of  harm  must  be  present,  although  the  potential  impacts  



may  never  develop  or  may  take  time  to  develop."   The  court  primarily  drew  from  several  



federal   circuit   court   decisions   interpreting   federal   statutes   with   "imminent   danger"  

                                                          41  as well as our decisions broadly interpreting  

requirements  to  cover  "potential"  harms,

AS  46.03.822.42  



                   The   superior   court   relied   on   the   evidence  presented   at   trial   to   find   that  



sulfolane "presents an  imminent  and  substantial  danger  to the  public  health"  under its  



interpretation  of  AS  46.03.826(5)(A)  -  that  it  "presents  a  reasonable  medical  concern,  



the   nature   of   which   is   serious,   and   the   threat   of   which   is   present   when   sulfolane   is  



released  in  the  environment."   The  State  called  Dr.  Ted  Wu,  a  DEC  employee  and  expert  



in  toxicology  and  environmental  chemistry  who  reviewed  the  evidence  of  contamination  



at the refinery.  He testified about a  number  of  studies  demonstrating sulfolane's toxic  



effects  when  animals  were  exposed  to  it,  which  could  indicate  potential  adverse  effects  



on  humans.   He  testified  that  studies  showed  sulfolane  exposure  caused  "convulsion[s]  



. . .  in  squirrel  monkeys  and  rats"  and  vomiting  in  squirrel monkeys, decreased kidney  



and   liver   functions   and   white   blood   cell   counts   in   guinea   pigs   and   rats,   increased  



aggression  in  dogs,  and  increased  fetal  absorption  and  deformation  in  fetuses  in  rats  and  



guinea  pigs.   Dr.  Wu  explained  that  squirrel  monkeys  were  more  susceptible  to  sulfolane  



than  were  rodents,  suggesting  that  humans  could  be  even  more  susceptible  than  squirrel  



monkeys.    Dr.   Wu   also   testified   that   sulfolane   is   more   toxic   than   about half   of   the  



hazardous   substances   already   identified   in   DEC's   default   groundwater   cleanup   level  



table   and   that   sulfolane   travels   in   groundwater   to drinking   water   wells   and   thereby

                   The  State  also  called  Dr.  Mary  Beth  Leigh,  a  professor  of  microbiology  at  



the   University  of   Alaska   Fairbanks,   to   provide   expert   testimony   about   her   own  



experiments   that   showed   sulfolane   was   toxic   to   a   bacterium   commonly   used   as   a  



screening  tool for toxicity to organisms.   The  State  called  former  DEC  Commissioner  



Larry   Hartig   and   former  North   Pole   Mayor   Bryce   Ward   to   testify   about   sulfolane's  



impact   on  public  welfare   and  the   factors  involved  in  gauging  public  welfare.   Hartig  



testified  that  he  understood  the  legislature's  intent  to  be  that  public  welfare  includes  the  



people's  "overall  health  and  welfare,"  as  well  as  their  "economic  well-being"  and  their  



"opportunity   to  have   a   living"   and   "subsistence."    Ward   testified   about   the  negative  



impact  sulfolane  contamination  had  on  the  North  Pole  community,  causing  residents  to  



be  upset and concerned about the amount of sulfolane  to which they were unwittingly  



exposed.  



                   Hartig  also  testified  that  DEC  considered  sulfolane  a  hazardous  substance

environment,"            a   phrase   that   is  virtually   identical   to   the   definition   of   "hazardous  



substance"  in  AS  46.03.826(5)(A).  



                   The State introduced Williams's written emergency medical  care policy  into  



evidence.   The  policy  described  possible  life-threatening  effects  of  sulfolane  if  inhaled,  



ingested,  or  in  contact  with  the  skin  or  eyes.   It  listed  "[c]ardiac  arrhythmias,  respiratory  



failure,   pulmonary   edema,   paralysis,   brain   damage,   liver   damage,  lung   tissue   and  



stomach  tissue  damage"  as  possible  side  effects  from  sulfolane  exposure.   



                   Williams  presented  deposition  testimony  from   Stephanie  Buss,  a  former  



DEC   employee   and  toxicologist.   When   asked  to   identify "every   single   fact   .   .   .  that  



would  indicate  that  sulfolane  is  and  presents  an  imminent  and  substantial  danger  to  the  



public  health   and  welfare,"   Buss   stated  that   "toxicity   studies   .   .   .   indicat[ed]   adverse  



health  effects"  and  proceeded  to  identify  various  studies.    She  also  referred  to  studies  



indicating  that  sulfolane  posed  dangers  not  only  to  public  health  and  welfare,  but  also  to  



"fish  and  vegetation."  



                   Williams  also  called  James  Fish,  a  DEC  employee  and  project  manager  for  



the   refinery   contamination   area.    Fish   testified   that   the   EPA   had   previously   treated  



sulfolane  as   a  hazardous   substance   at   a  refinery  in  Puerto  Rico.   He  testified  that  the  



EPA's   approach   to   the   Puerto   Rican   refinery   supported   DEC's   decision   to   consider  



sulfolane  a  hazardous  substance.   



                   The  superior  court  relied  heavily  on  Dr.  Wu's  testimony  to  determine  that  



sulfolane  is   a  hazardous   substance  under  AS  46.03.826(5)(A)  based   on  the   danger  it  



posed  to  public  health  and  welfare.   It  found  Dr.  Wu's  medical  concerns  about  sulfolane  



were  both  "reasonable  and  serious"  and  that "               [a]t  a  minimum,  sulfolane  exposure  can  



reduce  white  blood  cell  counts;  at  a  maximum  sulfolane  exposure  can  cause  death."   The

court also  found it notable that, while  operating the refinery,  Williams  itself treated  



                                                                                                                             

sulfolane in its emergency medical care policy as though it were life-threatening.  



                                                                                                                              

                    In addition to  sulfolane's demonstrated toxicity, the  superior court was

hazardous, but it was persuaded that the concentrations at the time of release "into the

                    The court also found that DEC's treatment  of sulfolane as a hazardous  



                                                                                                                               

substance under AS 46.03.826(5)(A) was entitled to deference.  The court reasoned that

that "the contamination posed an imminent and substantial threat" to the public health

The  State's  2014  complaint  alleged  that  "[s]ulfolane  is  a  hazardous  substance  within  the  



meaning of AS 46.03.745, AS 46.03.900, AS 46.03.826, and 18 AAC 75.990."   Williams  



initially admitted   that   allegation,  but   denied   that   DEC   "considered   sulfolane   to  be   a  



hazardous   substance  under   any   statute   or  regulation   at   any   time   during   [Williams]'s  



ownership   and   operation   of   the   North   Pole   Refinery."     Williams   later   amended   its  



answer,  retaining  the  sentence  denying  DEC's  classification  of  sulfolane  as  a  hazardous  



substance,  but  instead  asserting  that  the  State's  allegation that sulfolane  is  a  hazardous  



substance  was  a  "legal  conclusion  to  which  no  response  [was]  required."   But  Williams  



did  not  withdraw  an  earlier  stipulation  agreeing  that  "Flint  Hills  is  a  liable  landowner  and  



operator  under  AS  46.03.822(a)  for  sulfolane  releases."   



                   The superior  court gave some weight  to Williams's initial admission and  



its  stipulation.   The  court  found  that  Williams's  "first  answer  constitute[d]  an  evidentiary  



admission   that   sulfolane   is   a   hazardous   substance,   notwithstanding   Williams'[s]"  



amended  pleading,  finding  support  in  Brigman  v.  State,  which  recognizes  that  "[c]ourts  



often  admit  superseded  or  withdrawn  pleadings  in  civil  and  criminal  cases  on  the  theory  

                                                                   46   The  court  also  found  that  Williams  

that   they   constitute   evidentiary   admissions."                                                           



admitted that sulfolane is a hazardous substance when it stipulated as to Flint Hills's

AS   46.03.826(5)(B)   and   AS   46.03.826(7).                        The   court   found   that   sulfolane   was  



"released as  a  constituent  of  Williams'[s]  oil  spills"  and  that  "Williams had  numerous  



spills  of  gasoline  containing  sulfolane  at  the  refinery."   



                   Finally,  the  court  concluded  that  sulfolane  is  a  hazardous  substance  under  



AS 46.03.826(5)(C).   Subsection .826(5)(C) defines as hazardous any "substance defined  



as  a  hazardous  substance  under  42  U.S.C.  9601(14),"  CERCLA's  expansive  definition  



of  hazardous   substance  that  includes  "any  hazardous  waste  having  the  characteristics  



identified  under  or  listed  pursuant  to  section  3001  of  the  Solid  Waste  Disposal  Act  [42  



U.S.C.  § 6921]"  (a section better known as the Resources Conservation and Recovery  

Act  (RCRA)).48  The court found sulfolanemet the hazardous substance definitions under

                   Williams  argues that  the  superior court misinterpreted the  law when  it  

                                                                                                                           



found that  sulfolane met  any  of the  statutory  definitions  of hazardous  substance  in  

                                                                                                                          



AS 46.03.826(5).  Regarding subsection .826(5)(A), Williams argues that the court's

memorandum  adopting  a  tentative  definition  of  hazardous  substance,  Williams  alleges  



that  the   court improperly   concluded  that   "imminent   and   substantial   danger  to  public  



                                                                                                        50  

health"  meant  only  a  "reasonable  medical  concern  about  the  public  health."                        Williams  



argues  that  this  definition  of  "imminent  and  substantial  danger"  has  never  been  "adopted  



by  any  court,  applied  by  DEC,  or  advocated  by  any  party  during  five  years  of  litigation";   



that  it  runs  counter  to  the  plain  language  of  the   statute;  that  it  "threatens  to  deprive  a  



         49        (...continued)  



ed.   1934)).  



         50        This   misrepresents   the   superior   court's   definition.     The   court   did   not  



conclude that an "imminent and substantial danger" meant  only a "reasonable medical  

concern   about  the  public  health,"  but   also  that,   "given  the  modifier   'substantial,'  the  

nature  of  the  harm  giving  rise  to  concern  is  serious  and,  given  the  modifier  'imminent,'  

the  threat  of  harm  must  be  present,  although  the  potential  impacts  may  never  develop  or  

may  take  time  to  develop."   



                   Moreover,   the   court   ultimately   made   separate   findings   that   sulfolane  

presented   an   imminent   and   substantial   danger   to   the   public   health   and   welfare.   

Williams's  opening  brief  primarily  argues  against  the  danger  to  public  health  finding.   

Its  arguments   about  the  public  welfare   findings are   limited  to   a   single   footnote  in  its  

opening  brief   that   simply   incorporates   "all   the   above  reasons  why   sulfolane   is  not   a  

hazardous   substance   in   the   first  instance."     Williams's   reply   brief   claims   that   the  

arguments  are  interchangeable.   Williams  does  not  challenge  the  court's  factual  findings  

about  the  impact  on  North  Pole  residents  or  its  finding  that  residents'  concerns  about  

"economic  well-being  [and]  opportunity  to  have  a  living"  are  incorporated  in  the  public  

welfare  prong   of   the   definition,   and   fails   to   adequately   address   this   issue.    We   thus  

consider  Williams's   challenge  to the   court's   finding  waived.   See  Alaska  R.  App.  P.  

212(c)(1)(H)  (requiring  that  argument  section  "explain  the  contentions  of  the  appellant

defendant of the constitutional right to fair notice" under  Stock v. State;51 and that it is  



contrary  to  the  legislative  history.   Williams  also  argues  that  because  the  concentrations  



of  sulfolane  "had  decreased  dramatically  and  were  nowhere  near  the  ranges  cited  by  the  



court"  by  the  time  the  plume  reached  drinking  water  wells,  the  court  erred  by  finding  that  



sulfolane  was  hazardous  at  the  time  of  release.   



                 The  State  responds  that  Williams's proposed definition  of  "imminent"  is  



flawed  because  it  would  exclude   substances  causing  delayed  manifestations  of  harm,  



such   as  birth   defects   or   cancer.    The   State   emphasizes  that  the   statute  uses  the  word  



"danger"  rather  than  "harm"  to  signify the  possibility  of  harm,  rather  than  the  present  



existence  of  harm.   And  it  argues  that,  even  under  Williams's  proposed  interpretation  of  



AS  46.03.826(5)(A),  trial  evidence  supports  finding  sulfolane  is  a  hazardous  substance.   



The  State points to the numerous studies demonstrating  sulfolane's  harmful effects on  



animals.   The  State  asserts that there is no legal support for Williams's contention that  



"whether  a  substance  is  hazardous  should  turn  on  its  concentrations  in  the  environment  



after  decades  of  dilution."  



                 Williams  also  asserts  that  the  superior  court  improperly  relied  on  evidence  



from  Dr.  Wu  and  DEC  employee  Stephanie  Buss  because,  although  they  indicated  they  



believed   sulfolane   was   a   hazardous   substance,   they  did   not   state   explicitly   that   it  



"presents  an  imminent  and  substantial  danger  to  public  health."   Williams  argues  that  it  



was  error  to  infer  that   sulfolane  is   a  hazardous   substance,  pointing  to   a  ruling   on  the  



parties'  2018  motions  for  summary  judgment which discounted Dr. Wu's  affidavit for  



not  using  these  statutory  terms.   The  State  responds  that  "[n]o  rule  of  evidence  says  that

it does not use particular words from a statutory definition."  The  State also points out  



that Williams did not "cit[e] contrary evidence or explain [in its brief] why the studies  



do  not  show  that  sulfolane  is  dangerous."  



                   When we interpret a statute, we presume "that the legislature intended  every  



word,  sentence,  or  provision  of  a  statute  to  have  some  purpose,  force,  and  effect,  and  that  



                                                              52  

no   words   or   provisions   are   superfluous."                 We   apply   a   "sliding-scale   approach"   to  



interpret  the  language:   "[t]he  plainer  the  statutory  language  is,  the  more  convincing  the  



                                                                                     53  

evidence  of  contrary  legislative  purpose  or  intent  must  be."                     To  the  extent  possible,  we  



"interpret  each  part  or  section  of  a  statute  with  every  other  part  or  section,  so  as  to  create  



                                 54  

a  harmonious  whole."               Whether a   substance  meets  the  legal  standard  of  "hazardous  

substance"  is  a  "question  of  law  to  which  we  apply  our  independent  judgment."55  



                   We  are  not p      ersuaded  by  Williams's  arguments.   The  two  key  issues  are  



whether   "imminent"   dangers   under   AS   46.03.826(5)(A)   can   include   non-immediate  



dangers  and  whether  the  facts  support  concluding  sulfolane  is  a  hazardous  substance.  



                   Turning  to  the  first  issue,  we  note  that  because  the  parties  do  not  discuss  the  

legislative  history  of  the  statute,56  we look primarily to the plain meaning of the statute.

The  undefined  use  of  "imminent"  in  statutes and  treaties,  across diverse  subject  areas,  



                                                                     57  

has     plagued        legal      scholars       for    decades.             When        the     legislature        enacted  



AS  46.03.826(5)(A),  Black's  Law  Dictionary  defined  "imminent"  as  something  "[n]ear  



at   hand;   mediate   rather   than   immediate;   .   .   .   impending;   on   the   point   of   happening;  

threatening."58  It defined "danger" as "[j]eopardy; exposure to loss  or injury; peril."59  

                                                                                                                                 



Similarly, Merriam-Webster's  Collegiate  Dictionary  defined  "imminent"  as  "ready  to  



                60                                                                                            61  

take  place"        and  "danger"  as  "exposure  or  liability  to  injury,  pain,  or  loss."                   While  an  



"imminent  danger"  is  thus  typically  some  harm  that  is  threatening  to  occur  immediately,  



the  fact  that  harm  ultimately  did  not  occur  does  not  mean  that  the  harm  was  not  imminent  



          56        (...continued)  



AS  46.03.826(5)(A)  was  enacted  prior  to  subsection  .826(5)(C)  and  thus  could  not  have  

been  designed  to  expand  subsection  .826(5)(C);  and  (2)  making  conclusory  statements  

that  the  court's  interpretation  of  imminent  and  substantial  danger  "finds  no  support  in  the  

statutory   text   or the   legislative   history."    "[A]  party's  briefing   must   contain   its   own  

arguments   and   may   not   merely   incorporate   arguments   from   other   documents."

Williams's  legislative  history  arguments  were  insufficiently  briefed  and  thus  waived.

at  one  point.   Federal  case  law  cited  by  the  superior  court  and  both  parties  supports  this  



                                                     62  

interpretation  of  "imminent  danger."                  The  court's  interpretation  of  "imminent"  -  that  



"the  threat  of  harm  must  be  present,  although  the  potential  impacts  may  never  develop  



or  may  take  time  to  develop"  -  aligns  with  the  plain  definition  of  statutory  terms  as  well  



as  federal  case  law  interpreting  like  terms.  



                   Williams's  factual  and  evidentiary  challenges  to  the  hazardous  substance  



conclusion  also  fail  to  withstand  scrutiny.   Williams  does  not  cite  any  case  law  or  rules  



of  evidence  to  support  its  argument  that  expert  testimony  must  exactly  track  the  relevant  

statutory  text  at  issue.63  

                                   Alaska  Evidence  Rule  702(a)  allows  qualified  experts  to  rely  on  



their  "scientific,  technical,  or  other  specialized  knowledge"  to  express  opinions  that  will  



"assist  the  trier  of  fact  to  understand  the  evidence  or  to  determine  a  fact  in  issue."   There  



is  no  indication  that  it  would  be  improper  for  the  trier  of  fact  to  rely  on  expert  testimony  



if  the   expert  fails  to  repeat  verbatim  the   statutory  language  at  issue  while  offering  an  



opinion.   Dr.  Wu's  and  Buss's  testimony  demonstrated  that  sulfolane,  "when  it  enters  .  .  .

any  part  of  the  natural  habitat  in  which  they  are  found."               Dr.  Wu  testified  extensively  



about  sulfolane's  toxic  effects  on  animals  exposed  to  it.   And  Williams  mischaracterizes  



Buss's deposition testimony, alleging she concluded sulfolane was  a hazardous substance  



based  only  on  studies  showing  that  "sulfolane  has  the  potential  to  have  adverse  effects."  



(Emphasis  omitted).   But Buss also  discussed  a  study  showing  "significant  impacts  of  



high  concentrations  of  exposure."   Her  deposition  testimony  indicates  that  she  believed  



sulfolane  posed  an  imminent  and  substantial  danger  to  the  public  health  or  welfare,  but  



she   clarified   that   none   of   the   studies   to   which   she   referred   used   those   words   so   she  



avoided  saying  that  a  study  made  such  an  explicit  finding.   That  Dr.  Wu  and  Buss  never  



expressly   stated   "sulfolane   presented   an   imminent   and   substantial   danger   to   public  



health"  did  not  preclude  the  superior  court  from  making such  a  finding,  especially  in  



light  of  the  ample  evidence  suggesting  that  fact.   The  superior  court  did  not  err  by  relying  



on  Dr.  Wu's  and  Buss's  testimony  when  making  its  findings.  



                   Other testimony  from  Dr. Wu further supports finding sulfolane presents  



an  imminent and substantial danger to the public health or welfare.  He testified about  



studies  showing  negative  impacts  on  plants,  earthworms,  aquatic  invertebrates,  and  fish  



when   exposed   to   sulfolane,   including   a   study   demonstrating   impacts   on   embryonic  



development in  zebrafish  when  exposed to a range of sulfolane concentrations  equivalent  



to  concentrations  found  in  groundwater  near  refineries  around  the  world.   And  the  fact  



that  Williams  itself  treated  sulfolane  as  a  substance  with  life-threatening  characteristics  



while  handling  it  further  supports  the  court's  hazardous  substance  finding.   



                   The   superior   court   also   did  not   abuse   its   discretion  by   giving  weight  to  



         64        AS  46.03.826(5)(A).

site or incident" including "the costs of direct investigation,  containment and cleanup,  



removal,   and remedial   actions   associated   with   an   incident   or   site   undertaken   by   the  

department  .  .  .  as  well  as  the  costs  of  oversight."67  



                   The  superior  court  found  that  the  State's  and  Flint  Hills's  plans  to  "provide  



alternative  water  in  the  form  of  a  piped  water  expansion  project  [were] reasonable  and  



not  arbitrary  or  capricious."   There  was  expert  testimony  that  groundwater  remediation  



would likely cost at least  $6  million more than expanding the  piped water system, and  



would  take  decades  to  achieve.   The  court  found  "Williams  .  .  .  liable  for  the  estimated  



costs   of  the  piped  water   system,   $72,228,154,   as   an   appropriate  response   cost  under  



            68  

.822(a)."    Other  response  costs  included  those  incurred  by  Flint  Hills  to deliver  bulk  



and  bottled  water  in  the  interim  and  to  drill  new  public  wells  after  sulfolane  was  detected  



in  the  City's  source  wells.   The  interim  water  deliveries  were  part  of  a  project costing  



$27.67  million,  and  the  new  City  source  wells  cost  $4.39  million.   



                  Williams   argues  that  the   superior   court   erred   by   awarding   the   State  



response   costs   for   the   piped   water   system   and   new   wells,   claiming   the   piped   water  



system  was  unnecessary,  not  cost-effective,  and  unreasonable.   Williams  also  argues  the  



superior   court   erred   by   awarding   Flint   Hills   costs   for   bottled   water   to  North   Pole  



residents,   contending  that  new  wells   for  the   City   and   "providing   alternative  water  to  



residents  on  an  interim  basis"  were  unnecessary.  



                   Williams   points   to   several   environmental   conservation   regulations  to  



         67        18  Alaska  Administrative  Code  (AAC)  75.910(b)  (2021).  



         68        The   court   calculated   expected   cost   for   the   piped   water   system   -  



$72,228,154  - based  on  "payments  from escrow  to  date  by  the  State  of  $11,599,681  and  

$44,378,473  from  Flint  Hills;  an  additional  $16.25  million  is  expected  to  be  required  to  

complete  the project."   It then determined that Williams was equitably responsible for  

75%  of  the  State's  and  Flint  Hills's  future  costs  related  to  the  piped  water  system.

necessary  for  human  or  environmental  health.   For  example,  Williams  claims  there  was  



no  evidence  demonstrating  that  "the  low  levels  of  sulfolane  in  North  Pole  area wells  have  



caused  adverse  health  effects."   The  State  again  points  to  the  text  of  AS  46.03.822,  where  



the  extent  of  liability  and  recovery  is  untethered  to  findings  of  "necessity"  or  "cleanup  



                                                                                                                74  

levels."    The   State   argues   that Williams could   have   proposed   a   cleanup   level                       and  



Williams's  failure  to  participate  "in  the  regulatory  process  .  .  .  puts  it  in  a  poor  position  



to  now  raise  regulation-based  objections  to  DEC's  response."   Furthermore,  regulations  



expressly  allow  DEC to  require  a  responsible  person  to  provide  alternative  water  sources  



when  "toxicity  information  is  insufficient  to  establish  a  cleanup  level  for  a  hazardous  



                                    75  

substance   or   a  pollutant."         And,   as  discussed  below,   feasibility   studies   showed  that  



alternatives  to  the  piped  water  system  such  as  remediating  the  groundwater would  be  



costly,   difficult   to   implement,   uncertain   to   succeed,   and   could  pose   additional   risks.   



Thus  establishing  a  level  to  which  groundwater  concentrations  would  need  to  have  been  



returned  was  irrelevant  in  these  circumstances.   The  superior  court  properly  concluded  



that   the   statutes   did   not   require   the   State   to   prove   that   the   piped   water   system   was  



               76  

necessary.

proposed  alternative  cleanup  level).  



         75        18  AAC  75.345(d).  



         76        While  Williams  alleges  that  the  State  had  ulterior  motives  in  its  pursuit  of  



the   piped   water   system   -   to   "save   face   with   the   public"   and to remedy   other   non- 

sulfolane  contamination  problems  with  well  water  -  our  review  of  the  record  reveals  no  

such  bad-faith  motives.  



                   In  contrast,  Williams's  argument  borders  on bad faith when  it  selectively  

                                                                                                      (continued...)

----------------------- Page 36-----------------------

                    Williams  next  argues  that  the  piped  water  system  is  not  cost-effective,  and  



                                                                         77  

thus  is  not  "practicable"  as  required  by  regulation.                  Williams  alleges  that  "[n]either  the  



State  nor  Flint  Hills  offered  any  evidence  that  the  piped  water  system  was  the  most  cost- 



effective   remedy"   and   that   State   witnesses   conceded   that   this   was   not   a   factor   DEC  



considered.   While  the  State  mostly  focuses  on  the  absence  of  any  statute  requiring  that  



it  prove  piped  water  is  the  most  cost-effective  remedy,  it  also  points  to  witness  testimony  



discussing  the  benefits of  piped  water  over  other alternatives.   The  State  noted  that  its  



permanency,  cost,  safety,  and  reliability  made  piped  water  superior  to  delivering  bottled  



water or  to  "restor[ing] the  aquifer  to  its  natural condition."  Williams's  sole proposal  



besides  doing  nothing  was  to  conduct  air  sparging,  a  form  of  remediating  the  aquifer  that  



DEC,   as   well   as   Flint   Hills's   environmental   contractor,   had   already   considered   and  



          76        (...continued)  



relies  on  a  DEC  employee's  testimony to claim that the State sought "to remedy  water  

quality issues   unrelated   to   sulfolane   that   make   the   well   water   'unpalatable   without  

treatment.'  "   The  employee,  referring  to  aesthetic  differences,  said  the  water  was  "a  little  

unpalatable  without  treatment."   And  Williams's  references  to  other  contamination  are  

unsupported by the  record  and  are  irrelevant  to  assessing  the  response  costs  the   State  

incurred  out  of  concern for  the potential  public health and  welfare  impacts  from sulfolane  

contamination.  



          77        "Practicable" is defined as "capable of being designed, constructed, and

                    Williams cites 18AAC 75.325(f)(1)(D) to support its assertion. In relevant  

                                                                                                                     

part, this section instructs a responsible person, "to the maximum extent practicable, . . .

determined   would   be   costly,   ineffective,   and  could   pose   additional   risks   to   the  



community.  



                  Williams  further  asserts  that  the  piped  water  system's  cost  was  exorbitant  



rather  than  cost-effective  because  "[o]nly  86  private  wells  .  .  .  in  recent  years"  recorded  



measurements  of  at  least  20  ppb  of  sulfolane.   Williams  therefore  calculated  the  cost  of  



the  piped  water  amounted  to  "over  $837,000  per  affected  well."   The  State  responds  that  



the  statute  imposes  strict  liability  for  actual  damages  and  response  costs  rather  than  for  



                                                                78  

only   the   most   cost-effective   measures  taken.                 Flint   Hills   points   to   trial   testimony  



tending  to  show  cost-effectiveness  for  the  piped  water  system  was  considered  both  in  its  



design  and  at  trial.   The  record  also  reveals  that  the  sulfolane  plume  is  migrating  and  not  



expected  to degrade quickly,  and  that  the  uncertainty  about  effects  of  long-term exposure  



to  sulfolane  justifies  preventative  measures  such  as  the  piped  water  system.  



                  Even   if   the   statutes  or  regulations   required   that   response   costs   be  



"necessary"  and  cost-effective, the   State  persuasively  argues  that  the  record   supports  



such   a   finding.     The   superior   court   found   that  the   piped  water   system   would   be  



"reasonable  and  not  arbitrary  or  capricious"  as  an  alternative  water  source  because  it  is  



a  common  solution  for  large-scale  groundwater  contamination,  offers  an  effective  long- 



term   solution,   would   require   less   maintenance,   and   would   be   more   convenient.   



Furthermore,  testimony  from  Williams's  own  experts  supports  finding that  the  interim  



bottled  water  deliveries  and  piped  water  system  design  were  reasonable.  



                  The record supports the superior court's  decision to hold  Williams liable  



         78       See  AS  46.03.760(d)  (holding  responsible  party  "liable  to  the  state  .  .  .  for  



the  full  amount  of  actual  damages  caused  to  the  state  by  the  violation,  including"  costs  

for  abatement,  containment,  restoration,  and  emergency  response  costs);  AS  46.03.780

for  the  response  costs  for  the  piped  water  system,  interim  water  provisions,  new  wells,  



and   public   outreach.    The   court   did   not   clearly   err   by   finding   they   were   reasonable  



resolutions   to   the   sulfolane   groundwater   contamination.     We   affirm   the   award   of  



response   costs   to   the   State   and   Flint   Hills   for   Williams's   sulfolane   releases   under  



AS  46.03.822.  



                 3.	     The  superior  court  did  not  err  by  awarding  damages  for  loss  of  

                         access  to  groundwater  due  to  sulfolane  contamination.  



                 The  superior  court  determined  there  was  a "component  of  natural  resources  



damage"  from  sulfolane  "that  [was]  not  addressed  by  the  provision  of  alternative  water  



supplies,"   i.e.,   "loss   of   the   right   of   the   public   to   have   access   to   uncontaminated  



groundwater."  The court noted that some  people  might  prefer  using  well  water, and it  



noted  that  if  the  sulfolane  plume  migrates  -  as  is  predicted  -  to  areas  beyond  the  piped  



water  system,  the  impact  might  create  further  burdens  given  the  "inconveniences  and  



limitations"  of  installing  water  filtration  systems  for  well  water  in  those  areas.   The  court  



explained  that,  while  in  some  instances  it  might  not  be  strictly  necessary  for  residents  to  



use groundwater since  they might have alternatives, Williams's sulfolane releases had  



affected    people's      access    to    groundwater   due    to   pollution    and    this    was    an  



"uncompensated   'adverse  environmental  effect'  "  per  AS  46.03.760(a)(1) which  was  



"deserving  of  reasonable  compensation."   The  court  awarded  $2,533,125  to  the  State  for  



Williams's  75%  responsibility  for  the  groundwater-related  damages.   



                 Williams  claims  that  awarding  damages  based  on  the  public's  loss  of  "the  



option to  choose" to access uncontaminated groundwater was error.  Williams argues,  



first, that  no such right to uncontaminated groundwater exists under state law and that  



the c   ourt  based  this  right  only  on  "its speculation that   '[s]ome  people  may  prefer  well  



water,'  "  for  which  there  was  no  evidence.   Williams  further  argues  that  even  if  a  right  



to  access  uncontaminated  groundwater  existed,  it  is  held  by  the  public;  thus,  the  State  is  



                                                    -38-	                                              7658

not  harmed  and  cannot  recover  damages.   



                   Williams  is  incorrect  that  the  superior  court  based  the  existence  of  the  right  



solely  on  residents'  potential  subjective  preference  for  groundwater.   The  court noted  



that   preference   but   also   considered   other   reasons   why   access   to   groundwater   was  



important  to  the  public.   For  instance,  areas  not  served  by  the  piped  water  system  would  



have  limited  and  costly  means  for  access  to  clean  water.    



                   Williams   is   also   incorrect  that   there   is   no   basis   in   state   law   to   award  



damages   for   the   loss   of   access   to   groundwater.    Liability   for   such   contamination   is  



explicitly  laid  out  in  AS  46.03.760.   The  statute  provides  that  a  person  who  violates  the  

Act is liable to the  State for damages in the  form of a  civil  assessment.79  Even if there  



were   no   independent   right  of   access   to   clean   groundwater,   the   State   could   pursue  



damages  for  harm  to  this  natural  resource  based  on  Williams's  violations  of  the  Act.  



                   Furthermore,  Williams's  argument  that  the  State  cannot  pursue  legal  action  



for  harm  to  a  right  held  by  the  public  ignores  the  State's  role as  trustee  of  public  trust  



resources.   As  we  have   explained,   "[t]he  public  trust   doctrine  provides  that  the   State  



holds certain  resources  (such  as  wildlife,  minerals,  and  water rights)  in trust for public  



use,   'and   that   government owes a   fiduciary   duty   to   manage   such   resources   for   the  

common   good   of   the  public   as  beneficiary.'   "80            Alaska's  Constitution provides that

the public's use of groundwater resources, and the State could properly pursue damages  



             

for that interference.  



                                                                                                                

                    Williams also argues that even if a right to uncontaminated groundwater

of penalties.         Williams  points  out  that  the  superior  court  determined  that  imposing  



                                                                                                                               

damages  for the  cost  of restoring  the  aquifer to  its  original  condition  in  addition to  



                                                                                                                         

imposing damages for the cost of the piping system would be an "inappropriate double  



                                                                                                                              

assessment of damages."  Williams contends that it would therefore be irrational for the  



court to award both damages for the piping and damages to compensate the public for  



                                                                                                                         

the loss of the option to choose well water as that, too, would be an inappropriate double  



assessment.  



                                                                                                                         

                    We disagree with Williams's characterization of the damages as a double

"economic   savings   realized   by"   the   violator   due   to their   noncompliance.   (Emphasis  



added.)  Section  .780 allows costs for restoration following harm  to natural resources,  



providing   for   damages  in   "an   amount   equal  to the   sum   of  money  required  to  restock  



injured land   or  waters,  to  replenish   a   damaged   or   degraded  resource,   or  to   otherwise  



                                                                                                 91  

restore  the  environment  of  the  state  to  its  condition  before  the  injury."                 



                   The   superior   court   explained  that  the  piped  water   system   "substantially  



replaced   the   damaged   aquifer"   in   "an   economic   usage   sense,"   and   for   this   reason  



awarding  the  cost  of  restoring  the  aquifer  in  addition  to  the  cost  of  the  piping  would  be  



a   double  recovery.    The   court   also   determined  that   awarding  restoration   costs  twice,  



under  both   subsection   .760(d)   and   subsection   .780(b),  would  be   duplicative  because  



these  were  the  same  categories  of  loss.   



                   However,  the   superior   court   found  that  the  public's  loss   of  its   ability  to  



access  uncontaminated  groundwater  was  an  independent  harm that  was  not  addressed  by  



providing  alternate  water  supplies.   We  agree.   The  superior  court  explained  that  the  loss  



of  access  is  an  independent  harm:   the  plume  might  migrate  further  to  areas  that  do  not  



have  piping  and,  consequently,  alternatives  would  be  inconvenient  and  limited.   New  



construction   or   uses   -   including   subsistence   uses   like   growing food -   within   the  



existing  plume  but  outside  the  piping  area  will  be  affected  by  the  limited  alternative  ways  



to  obtain  clean  water.   Furthermore,  the  damages  awarded  for  loss  of  groundwater  were  



neither  restoration  damages  covered  by  section  .780  nor  a  cost  expended  by  the  State  in  

                                                     92 under subsections .760(a)(2) or .760(d); rather,  

"attempted  correction  of  the  violation"

the   groundwater   damages   were   compensation   for a   distinct   "adverse   environmental  



effect[]"  provided  for  in  subsection  .760(a)(1).   Awarding  damages  based  on  the  loss  of  



groundwater  access  was  not  duplicative  or  unfounded,  and  the   superior  court  did  not  



abuse  its  discretion  by  awarding  compensation  for  this  loss.  



                   Williams  raises  a third challenge to the superior  court's  award  under  section  



.760.   Williams  contends  that,  even  if  a  groundwater  access  right  exists,  it  could  only  be  



compensated  as  natural  resource  damages  under  section  .780.   Williams  does  not  explain  



why   section   .760   would   not   apply.    The   language   in   subsection   .760(a)(1)   allowing  



compensation  for  "any  adverse  environmental  effects"  is  broad  and  allows  for  recovery  



related  to  the  groundwater  access  issue.  



                   Williams  further  claims that AS 46.03.760(a)(1) "requires a specific finding  



on   the   'degree   to   which   [Williams's   releases   of   sulfolane]   degraded   the   existing  

environmental  quality.'  "93   Williams contends that the superior court did not, and could  

                                                                                                                  



not, make such a finding. We have not had occasion to interpret whether this subsection  

                                                                                                           



requires such a finding, or whether it is only one of many possible factors a court may

degradation  in  this  case  was  established:   previously  potable  water  had  been  determined  



to  be  unusable  for  drinking  and  related  purposes  throughout the  three-and-a-half-mile  



long  -  and  spreading  -  plume.  



                  It  is  unclear  why  Williams  claims  the court "could  not"  have  made  a  finding  



on   the   degree   of   degradation.    Even   if   true,   that   argument is   unpersuasive   because  



Williams    fails   to   understand  the   purpose    of    liquidated    damages    in   redressing  



environmental  violations.   As  the  superior  court  explained,  liquidated  damages  may  be  



                                                                          95  

used  when  the  measure  of  actual  damages  is  uncertain.                 The  uncertainty  often  inherent  



in  determining  the  environmental  impacts  of  pollution  is,  in  part,  a  reason  that  liquidated  



damages  were  made  available  by  the  legislature.   It  would  be  nonsensical  in  this  statutory  



context  to  preclude  an  award  of  liquidated  damages  due  to  uncertainty  as  to the  exact  



degree   of   degradation.    The   civil   assessment   statute  provides   for   liquidated   damages  



within   a   predetermined   range,   limited   by   a   ceiling established   by   the   legislature,   to  



enable  an  award  for  damages  that  are  uncertain  and  difficult  to  value.   The  court's  choice  



of  damages  within  that range  was  guided  by  factors  listed  in  the   statute  and  does  not  



reflect  an  abuse  of  discretion.  



                  Williams adds that there can be no  finding  that sulfolane "contaminated"  



the  aquifer  because   18  AAC  75.990(22)  defines  "contaminated  groundwater"  as  water  



"containing  a  concentration  of a hazardous substance that exceeds  the  applicable  cleanup

level."     It   claims   that   because   no   such   cleanup   level   has   been   set,   there   is   no  



"contamination"   of   the   groundwater and   instead   the   State   was   given   a   "free  pass   to  



recover  without  an  objective  standard."   This  argument  is  unpersuasive.   As  discussed,  



18  AAC  75  regulates  and  facilitates  site  cleanup.   It  does  not  purport  to  define  or  set  out  



the  measures  for  all  potential  damages  available  under  the  environmental  conservation  



statutes.   Thus,  applying  a  definition  of  "groundwater  contamination"  drawn  from  these  



cleanup   regulations   is   largely   irrelevant   to   determine   whether   the   aquifer   was  



contaminated  in  violation  of  a  provision  of  AS  46.03.   The  superior  court  correctly  said  



as  much   in   its   orders.     Second,   the   provisions   that   are   related   to   cost   recovery   in  



18  AAC  75.910  were  promulgated  pursuant  to  AS  46.03.760(d)  and  AS  46.03.822  (as  



well   as   other   statutes   not   relevant   here).     To   the   extent   that   definitions   from   the  



administrative  regulations  apply  to  damages  assessments  in  AS  46.03,  they  would  apply  



only  to  the  calculation  of  "actual  damages  caused  to  the  state  by  the  violation"  associated  



with   remediation   and   restoration   under   AS   46.03.760(d),   rather   than   to   liquidated  



damages   for   "any   adverse   environmental   effects   caused   by   the   violation"   under  

                               96   Williams acknowledges as much, stating that "18 AAC 75.910

used  sulfolane  because  "DEC  allowed  Williams  to  leave  it  in  the  ground  .  .  .  and  never  



once  told  Williams  it  was  violating  the  law  by  doing  so."   We  are  not  persuaded.   When  



Williams  reported  it  had  detected  sulfolane  in  the  refinery  groundwater,  DEC  experts  



expressed  uncertainty   and   some   concern   about the   substance,   for  which   there  was   a  



paucity   of   toxicity   information.    DEC   admitted   its   lack   of   information   and   advised  



Williams   to   monitor  its   releases   while   DEC   investigated   the   hazardous   nature   of  



sulfolane.   These  actions  are  not  equivalent  to  permitting  sulfolane  releases.   Moreover,  



as  the  State  correctly  argues,  Williams's  use  of  sulfolane  may  have  been  allowed,  but  its  



releases  into  the  soil  and  water  were  not;  such  releases  would  have  required  a  permit  that  

Williams  did  not  obtain.98

          98        The   superior   court   concluded  likewise   in   an   order   denying   summary  



judgment  to  both  Williams  and  the  State  for various  claims:   "   '[U]npermitted'  means  

without  'the  authority  of  a  valid  permit  issued  by  the  department  or  by  the  Environmental  

Protection   Agency.'    Because   [Williams]  has   conceded   that   it   did  not  have   a  permit  

issued   by   the   DEC   or   EPA   to   release   sulfolane,   its   release   of   that   substance   was  

unpermitted."   And  testimony  at  trial  demonstrates  that  Williams's  employees  knew  they  

did   not   have   the   requisite  permits   to   release   sulfolane.    See   AS   46.08.900   (defining  

"release"  and  "permitted  release").

not  punitive,  but  is  rather  a  compensatory  remedy  to   spread  costs among  responsible  



parties  so  they  are  not  borne  solely  by  the  public.   For  these  reasons,  it  is  not  punitive  to  



assess  damages  over  the  entire  period  of  Williams's  refinery  operations  in  North  Pole.  



                 In   sum,   the   superior  court   did   not   err   by   assessing   damages   under  



subsection .760(a) for the adverse effect of sulfolane  pollution on groundwater and its  



impact  on  the  public's  ability  to  access  the  groundwater  for  consumption.   The  superior  



court  also  properly  interpreted  the  scope  of  damages  permitted  by  sections  .760  and  .780,  



made   the   requisite   factual   findings   without   clear  error,   and   properly   exercised   its  



discretion  when  determining  awards  that  were  neither  duplicative  nor  punitive.  



                 4.	     It  was  error  to  issue  injunctive  relief  by  reference  to  supporting  

                          documents,   but   the   superior   court  did   not   err   by   granting  

                          declaratory  relief.  



                 The superior  court awarded injunctive and declaratory relief to the State and  

Flint  Hills  under  AS  46.03.765  for  PFAS-related  claims.100  

                                                                            The  court  found  "PFOS  and  



PFOA   are   hazardous   substances"   under   AS   46.03.822   and   are   "[t]he   compounds  



encompassed   by   the   acronym   PFAS."     The   court   also   found   that  no  evidence   was  



         100     AS  46.03.765  affords  the  court  "jurisdiction  to  enjoin  a  violation  of  this  



chapter  .  .  .  or  of  a  regulation,  a  lawful  order  of  the  department,  or  permit,  approval,  or  

acceptance,  or  term  or  condition  of  a  permit,  approval, or acceptance issued  under  this  

chapter."  



                 Williams  also  argues  that  the  superior  court  erred  when  it  chose  not  to  refer  

onsite   PFAS   claims   to   DEC   under   the   doctrine   of   primary  jurisdiction.     When   the  

superior   court  properly  has  jurisdiction,   its   decision  to  refer   an   issue  to   an   executive  

agency   is   plainly   within   its   discretion  and   is   informed   by   factors   such   as   judicial  

economy  and  administrative  expertise.   See  Seybert  v.  Alsworth ,  367  P.3d  32,  39  (Alaska  

2016).   The   superior  court  did  not  abuse  its discretion, especially  in  light  of  years  of  

pretrial  litigation of this issue  and  DEC's  determination  that  Williams  was  responsible  

for PFAS and other hazardous substance contamination during its tenure.   Referral would  

not  have  served  the  purposes  of  the  primary  jurisdiction  doctrine.

The  superior  court  concluded  in paragraph  3(a)  of the judgment  that Williams  was  



"strictly, jointly, and severally liable for sulfolane, [and] PFAS . . . releases, including  



                                                                                                                              

liability for the State's future response costs." It therefore declared in paragraph 3(b) that  



                                                                                                                                

the  State could recover 75% of its future costs related to the piped water  system.  In  



                                                                                                                              

paragraph 3(d) of the judgment, the court further ordered Williams to "perform and pay

remedies   at   law   are  required   elements   for   common   law   injunctive   relief,                         the   State  



argues  that  AS  46.03.765  grants  the  court  "jurisdiction  to  enjoin  a  violation"  of  Title  46,  



                                                                                                        102

Williams  argues  that  AS  46.03.765  permits  only  "temporary  or  preliminary  relief"  and  



is   meant   to   provide   DEC   "with   a   tool to stop   a   polluter   from   continuing   to   release  



contaminants   until   final   relief   may   be   obtained."     But   the   statute   does   not   prohibit  



permanent   injunctions;   it   merely   provides   additional   requirements   for   temporary   or  

preliminary  relief  due  to  the  reduced  opportunity  for  due  process  in  such  situations,103  



further   indicating   that  permanent   injunctions  -  which   do  not   entail  those   same   due  



process   concerns   -   are   permitted.     And   even   those   additional   requirements   for  



                                                                                                          104  

temporary  or  preliminary  relief  fall  short  of  requiring  irreparable  harm.                              Williams's

arguments  that  the  injunction  should  be  vacated  for  failing  to  meet  necessary  elements  



are  therefore  unpersuasive.  



                   Williams   next   argues   that   paragraphs   3(d)   and   3(e)   of   the   court's   final  



judgment violate Alaska Civil Rule 65(d) for being too "vague" and "open-ended."   Civil  



Rule  65(d)  provides  in  relevant  part  that  "[e]very  order  granting  an  injunction  .  .  .  shall  



set  forth  the  reasons  for  its issuance;  shall  be  specific  in  terms;   [and]  shall  describe  in  



reasonable  detail,  and  not  by  reference  to  the  complaint  or  other  document,  the  act  or  acts  



sought   to   be   restrained."    First,   Williams   argues paragraph   3(d)   of   the  judgment   is  



impermissibly  vague  because:   (1)  "it  identifies  no  'remediation  and  cleanup  efforts'  that  



Williams  must  undertake  and  the  Judgment  refers  to  documents  that  did  not  yet  exist";  



(2)  "the  injunction's  geographic  scope  to  remedy  and  clean  up  sulfolane  is apparently  



limitless";  and  (3)  "there  is  no  time  limit  on  Williams'[s]  obligations,  which  exposes  



Williams   to liability   for   future   costs   to  remedy  releases   to  which   it  played  no  part."   



Williams  challenges  paragraph   3(e)  of  the  injunction  for   similar  reasons:   it  "broadly  



purports  to  make  Williams  responsible  forever  for  sulfolane  contamination  'beyond  the  



Refinery  property,'   "   and   "incorporates   all   'applicable'  Alaska   laws,  without   further  



guidance or specificity"  leaving  Williams  unable  to  determine  exactly  what  conduct is  

required.105

                    The   State   argues  that   the   order   satisfies   Civil   Rule   65(d)'s   specificity  



requirements  by  drawing  comparisons  to  an  Idaho  federal  district  court  opinion  -  Idaho  



                                                                106  

Conservation  League  v.  Atlanta  Gold  Corp.                        The State  argues  that,  similar  to  Idaho  



Conservation  League,  the  court  properly  ordered  Williams  "into  compliance  .  .  .  without  



directing   every   step   .   .   .  because   the   duration of   the   contamination   is   indefinite   and  

Williams'[s]  violations  are  longstanding  and  serious."107

"site   clean-up   rules   -   which  the  judgment   refers   to   -   are   specific   enough   to   put  



                                                         108  

Williams  on  notice  of  what  it  must  do,"               a  fact  demonstrated  after  the  judgment  when  



"Williams   managed   to   twice   submit   -   and   gain   approval   of   -   monitoring   and  



characterization plans."   Third, the State argues that the cases upon which Williams relies  



in  labelling  the  injunction  as  an  "obey  the  law"  injunction  are  distinguishable.   Finally,  



the   State   disregards  Williams's   concerns   over   the   injunction's   geographically   and  



temporally  unlimited  reach  because  the  sulfolane  plume  is  similarly  unlimited.   Williams  



replies  that  the   State   fails to   show  that   "the  injunction  meets  Rule   65(d)'s   specificity  



requirements"  and  that  the  distinctions  between  the  cases  Williams  cites  and  the  facts  at  



          105       (...continued)  



                   Williams  does  not specifically challenge paragraph 3(e)(ii)  of the judgment.   

To  the  extent  paragraph  3(e)(ii)  is  distinct  from  paragraph  3(d)  -  both  require  PFAS  

cleanup   but   the   latter   requires   PFAS   "characterization,   monitoring,   reporting   [and]  

containment" at the refinery  - we consider  any  argument against it insufficiently briefed  

and  therefore  waived.

issue  are  immaterial.  



                 We   agree   that   the   injunctive   relief   did   not   satisfy   Civil   Rule   65(d)'s  



specificity  requirements.   Rule  65(d)  requires  that  injunctions  "describe  in  reasonable  



detail,  and  not  by  reference  to  the  complaint  or  other  document,  the  act  or  acts  sought  to  



be  restrained."   The  paragraphs  of  the  judgment  that  Williams  challenges  -  paragraphs  



3(d),  3(e)(i),  and 3(e)(iii) - do not describe on their own,  with  reasonable  specificity,  



the   remediation   and   cleanup   efforts   Williams   will   need   to   undertake.     The   court's  



accompanying  Memorandum  of  Decision  includes more specificity,  but  the  parties  do  



not  discuss  whether  it  is  specific  enough  to  satisfy  Rule  65(d)  or  whether  mere  reference  



to   the   Memorandum   of   Decision   satisfies   Rule   65(d).    We  remand   the  judgment   for  



injunctive  relief  for  more  clarity  and  to  explicitly  incorporate  -  not  by  reference  -  the  



language  from  the  Memorandum  of  Decision,  statutes,  administrative  code,  and  other  



documents  to  which  the  superior  court  refers.  



                         b.       Challenges  to  the  declaratory  relief  



                 Williams  next  challenges  the  superior  court's  declaratory  orders  on  PFAS  



at   paragraph   3(a)   of   the   court's   final   judgment.     Williams  argues  that   the   court  



improperly  declared  Williams  liable  for  PFAS  generally  when  only  PFOS  and  PFOA  



were  ever  mentioned  at  trial;  that  "the  State  and  Flint  Hills  only  presented  evidence  that  



Williams  used  a  product  that  included  PFOS,"  and  that  Flint  Hills  should  shoulder  some  

of  the  blame  for  PFAS.109  



         109     As  it  did  with  respect  to  the  injunctive  relief  discussed  above,  Williams  



argues  that  the  declaratory  relief  for  PFAS  improperly  extends  into  the  future.   Because  

the  court's o  rder  holds  Williams  liable  for  future  costs  related  to  the  PFAS  it  released  

prior  to  the  trial  date,  this  portion  of  the  court-awarded  relief  is  sufficiently  specific  and  

does  not  improperly  extend  into  the  future.  



                 Williams  also  argues  that  the  "declaratory  relief  in  favor  of  Flint  Hills  .  .  .  

                                                                                            (continued...)  



                                                    -53-                                               7658
  


----------------------- Page 54-----------------------

                   As   Williams   acknowledges,   "   'PFAS'   is   not   a   single   substance,  but   an  



umbrella  term  referring  to  a  diverse  category  of  man-made  chemicals,"  including  PFOS,  



                         110  

PFOA,  and  more.             At  trial,  Williams  representative  Randy  Newcomer  testified  that  



between   1991  and  2000  Williams  used  only  one  company's  brand  of  aqueous  foams  in  



its   fire   response   practices,   and   he   agreed   that   the   foams   contained   "perfluoroalkyl  



substances"  including  -  but  not  necessarily  limited  to  -  PFOS.   Dr.  Wu  also  testified  



that   the   company's   foams   marketed   and    sold   during   that   time   listed   "organic  



fluorochemicals"  as  an  ingredient,  another  phrase  for  the  "PFAS  class  of  compounds,"  



including   "PFOS   and   PFOA."    In   addition,   Williams   admitted   that   "releases   of   .   .   .  



perfluorochemicals   occurred"   during   its   tenure   at   the   refinery.     There   was   also  



contemporary  evidence  of  PFAS  contamination  more  broadly,  not  just  PFOS,  in  the  soil  



and  groundwater  at  the  refinery.   Though Williams  points  to evidence  suggesting  that  



Flint   Hills   could  have  used   PFAS   during   its   tenure   at   the  refinery,   Williams   fails   to  



          109      (...continued)  



already  was  rejected  because  Flint  Hills  had  an  adequate  remedy  at  law."   For  support,  

Williams   cites   a   2017 pretrial   order   dismissing   Flint   Hills's   "claims   for   declaratory  

judgment  and  specific  performance"  against  Williams  as  barred  by  res  judicata  in  light  

of  Flint Hills I, 377  P.3d  959  (Alaska  2016).   But  the  declaratory  relief  sought  in  Flint  

Hills  I   concerned   sulfolane  rather than   PFAS,   did  not   involve   State   claims,   and  was  

dependent  on  the  availability  of  other  legal  remedies.   Id.  at  973-74.   Williams  does  not  

explain how these  important differences would justify barring declaratory relief based  

on  res  judicata  and  we  see  no  reversible  error  on  this  issue.   See  Patterson  v.  Infinity  Ins.  

 Co.,  303  P.3d  493,  497  (Alaska  2013)  ("A  judgment  is  given  res  judicata  effect  by  this  

court   when   it   is   (1)  a   final  judgment   on   the   merits,   (2)   from   a   court   of   competent  

jurisdiction, (3) in a  dispute  between the  same  parties (or their privies) about the same

identify  any  evidence  that  Flint  Hills  actually  did  use  PFAS-containing  products.111  



                   Because  the  record  shows  that  Williams  released  PFAS  during  its  tenure,  



the  burden  was  on  Williams  to  prove  that  it  did  not  use  particular  PFAS  chemicals  or  to  



                                                                112  

establish  that  another  entity  was  also  liable.                 The  superior  court  did  not  err  when  it  



declared  that  no  evidence  was  presented  demonstrating  Flint  Hills  used  PFAS  during  its  



          111      Williams  does  not  raise  the  argument  that  Flint  Hills  should  be  liable  under  



AS  46.03.822  for  PFAS  contamination  due  to  its  status  as  current  owner  of  the  facility  

from  where  PFAS  was  released.   See  AS  46.03.822(a)(2),  .826(9)  (assigning  liability  to  

owner   of   facility   from  which  hazardous   substance   is  released   and   defining   "release"  

broadly  such  that  PFAS  "leaching"  from  the  refinery  could  fall  within  definition);  see  

also  AS  46.03.822(c)  (maintaining  liability  for  refinery  owners  that  purchased  property  

with  knowledge  of  earlier  releases  of  hazardous  substance).   



                   On  appeal,  Williams  points  to  several  sections  of  the  record  purporting  to  

show  that  "Flint  Hills  used  substantial  amounts  of  'PFAS'  in  fire-training  exercises  and  

'hot   work'   at   the   refinery."     Some   of   that   "evidence"   consists   of   Williams's   own  

proposed   findings   of   fact and  testimony   from   some   of   its   own  witnesses   speculating  

about  the   source   of  PFAS   detections  that   occurred  "upgradient"   (i.e.,  in  the   opposite  

direction  of  water  seepage)  of  firefighting  areas.   Williams  also  cites  a  2018  DEC  report  

detailing  PFAS  sampling  at  the  refinery  that  indicates  Flint  Hills  purchased  firefighting  

foams, but not that those foams  contained PFAS.  Williams  additionally points us to a  

lengthy  2013  environmental  report  without  explaining  its  relevance,  but  that  report  was  

excluded   from   trial   on   hearsay   grounds   and,   in   any   event,  it  suggests   Flint   Hills  

purchased  foams  without  PFOS  or  PFOA.   



                   To   the   extent   there   may   have   been   evidence   tying   Flint   Hills   to   PFAS  

contamination  at  the  refinery,  we  consider  the  argument  waived  for  insufficient  briefing  

and  failure  to  cite  relevant  evidence  in  the  record.   See  Casciola  v.  F.S.  Air  Service,  Inc.,

for  PFAS  contamination.  



                    5.        Williams's  right  to  due  process  was  not  violated.  



                    Williams  argues that DEC's  enforcement a   ction  and  the  superior  court's  



finding  of  liability  under  section  .822  and  subsection  .826(5)(a)  violated  the  Due  Process

Clause  of  the  U.S.  Constitution                 and  article  I,  section  7  of  the  Alaska  Constitution 



                                                                                                                     

because Williams did not have "fair notice" that its conduct was prohibited.  



                                                                                                                               

                    Williams implies that the hazardous substance statutes and regulations are  



                                                                                                                       

too  vague  to  make  it  clear whether  sulfolane fell within  the  definition  and whether  



                                                                                                                    

Williams could be liable for its release.  Williams claims it relied on agency statements  



                                                                                                                      

to understand its responsibility. Williams specifically contends that "DEC told Williams  



                                                                                                                        

that sulfolane was not a hazardous substance and not regulated" and that DEC actually  



                                                                                                                              

"allowed sulfolane to stay in the ground."  As a result it claims that "DEC's actions and  



                                                                                                         

communications gave Williams no notice that its conduct created a substantial risk of  



                                                                                                              

actual harm."  Williams also claims that the superior court's "eve-of-trial interpretation"  



                                                                                                                               

of the terms "hazardous substance" and "imminent and substantial danger" violated the  



                     

principles of fair notice because they were a "reversal" of DEC's initial position and a  



                                                               

prior superior court decision in the case.

a   statute   must   not   be   so   vague   that   people   cannot   know   what   they   must   do   or   are  



prohibited  from  doing.   We  have  explained  that  even  if  a  statute  might  in  some  contexts  



be  too  vague  to  give  adequate  notice,  it  "may  still  pass  muster if:   (a)  there  can  be  no

through residential areas.126                This act obviously fell within the statutory definition of

We acknowledged that the term "potentially harmful" in the definition of "pollution"  

                                                                                                                    



might be vague enough to require a narrowing construction, and we added an element  

           

requiring foreseeability which would be used in future applications.128   But we affirmed

conduct  so  clearly  fell  within  the  "hard  core"  of  prohibited  conduct.                   Additionally,  we  



explained  that  the  need  for  environmental  protection,  the  increasing  number  of  laws  and  



regulations  governing  disposal  of  substances  used during commercial activity,  and  the  



need   for   the   legislature   to   make   broad   statutes   to   balance   economic   growth   with  



environmental  protection  all  supported  our  conclusion  that  the  antipollution  provisions  



at  issue  were  not  unconstitutionally  vague  on  their  face  and  that S                tock was clearly  on   

notice  that  discharging  raw  sewage  into  waterways  was  improper.130  



                   In  Williams's  case,  it  is  possible  that the  hazardous substance  provisions  



of  section  .822  and  the  statutory  definition  of  hazardous  substances  in  subsection  .826(5)  



could  be  vague  in  some  instances.   But  the  superior  court's  findings  about  sulfolane  lead  



us   to   conclude   sulfolane   falls   within   the   "hard   core"   of   the   definition   of   hazardous  



substance.   And  Williams  itself  treated  sulfolane  as  hazardous.   Furthermore,  Williams  



may  have  been  allowed  to  use  sulfolane,  but  it  knew  that  it  was  not  permitted  to  simply  



dispose  of  the  substance  in  any  manner  it  wished.   These  facts  indicate  that  Williams  was  



on  notice  of  the  potential  for  liability  under  a  gamut  of  antipollution  statutes,  including  



those   related   to   hazardous   substances.     We   conclude   that   the   statute   is   not   so  



impermissibly  vague  that  it  violates  Williams's  right  to  due  process.  



                   We  also  disagree  that  DEC's  communications  or  actions  prior  to  litigation  

resulted  in  a  lack  of  fair  notice  to  Williams.131   DEC's failure to pursue an enforcement

         130       Id.  at   12-13.  



         131       The superior  court rejected this  argument in Williams's cross-motion for  



summary  judgment  because  it  determined  that  fair  notice  would  be  required  only  when  

an  agency  "depart[ed]  from  its  long-established  regulations  or  adjudications."   But  fair  

notice requirements apply even  when there have not been regulations or adjudications

action with regard to sulfolane was not  "acquiescence"                            to  or  approval  of  Williams's  



conduct.   In  its  communications  with  Williams,  DEC  acknowledged  that  sulfolane  was  



not  then  regulated  as  a  hazardous  substance  because  very  little  was  known  about  it  and  



there  was  a  "lack  of  EPA  reviewed  toxicity  data,"  and  DEC  said  it  first  needed  to  gather  



more   information  regarding   sulfolane   and  the  pollution   issuing   from  the  refinery.    It  



required  Williams  to  conduct  further  monitoring  and  stated  that  it  would  follow  up  with  



further   clarification   or   action.     Though   Williams   claims   DEC's   communications  



constituted   "written   determinations"   that   sulfolane   did  not   pose   a   hazard,   DEC  



communicated  that   sulfolane  was  not  regulated   at  the  time,  not  that  it  had  ultimately  



concluded  it  was  not  hazardous.   We  conclude  the  superior  court  did  not  clearly  err  when  



it  found  DEC  had  not  promulgated  prior  interpretations  about  sulfolane  in  legal  briefs,  



regulations,  or  adjudications  that  Williams  might  have  relied  on  to  claim  sulfolane  was  

not  hazardous.133  



          131      (...continued)  



on  point.   The  U.S.  Supreme  Court  has  recognized  that  while  agencies  have  enforcement  

discretion  and  interpretive  latitude,  if  the  statutory  interpretations  are  unreasonable  or  if  

the   conspicuous   inaction   appears   to be   for no   reason   other   than   acquiescence,   "the  

potential  for unfair surprise is acute."   Christopher v. SmithKline Beecham Corp., 567  

U.S.   142,   158  (2012).   Agency  actions  beyond  regulations  and  adjudications  serve  to  

inform  regulated  entities  and  therefore  are  relevant  to  the  fair  notice  inquiry.   However,  

as  we   discuss  below,  DEC  did  not  cause  Williams  unfair  surprise.  



          132      See  id. (recognizing many reasons  for agency lack  of enforcement and  

                                                                                                                       

finding lack of fair notice where only possible reason was acquiescence).  

                                                                                                           



          133      The cases Williams cites as support for its argument are distinguishable on

                   Agencies   are   free  to   create   and   change  policies   for  matters  within  their  



purview,   as   DEC   did   when   it   decided   to   regulate   sulfolane   and   treat   Williams   as   a  



responsible   party.     An   agency   should   indicate   that   it   is   changing   its  position   and  



demonstrate  good  reasons  for  such a  change,  but  it  does  not  need to  "provide  detailed  



justifications  for  every  change"  and it is not the court's role to ask whether the chosen  



                                                                                     134  

policy  is  better  or  best  -  only  whether  it  conforms  to  reason.                 Based  on  the  evidence  



presented  at trial, the superior  court concluded that  DEC reasonably determined  sulfolane  



to be   a   "hazardous   substance"   and   that   unpermitted   disposal   was   a   violation   of   the  



antipollution  provisions  of  Title  46,  Chapter  3.   We  see  no  error  with  that  conclusion.  



                   Williams  also argues that the superior  court's own rulings  deprived  it  of due  



process   because   the   court   promulgated   an   "eve-of-trial   interpretation of   'hazardous  



substance'  "  and  "imminent  and  substantial  danger"  under  section  .822  and  subsection  



 .826(5)  that  contradicted  "both  the  DEC  position  on  sulfolane  during  2001-2003  .  .  .  and  



the  intervening  decision  of  the  same  court."   Williams  does  not  cite  case  law  to  support  



its  claim,  does  not  specify  exactly  how  the  superior  court  acted  unlawfully,  and  does  not  



indicate  how  it  was  prejudiced.   We  consider  arguments  that  are  given  cursory  treatment

without  any  support  to  be  waived.                And  we  do  not  see  how  the  superior  court  carrying  



out  its  obligation  to  interpret  the  relevant  statute  -  issuing  rulings  on  a  matter  of  law  that  



was   consistently   contested throughout   the  proceedings  -   could  have  worked  unfair  

surprise  on  Williams  or  violated  its  right  to  fair  notice.136  



                   6.	       Imposing          civil    liability      for     past     releases        was      not     an  

                             unconstitutional  taking.  



                   Williams          argues       that      the     superior        court's       interpretation          of  



AS 46.03.826(5)(A) is an  unconstitutional regulatory or judicial  taking under the U.S.  

and    Alaska    Constitutions.137  

                                                  Williams    argues    the   judgment    imposes    severe,  



unforeseeable   retroactive   liability,   which   it   could   not   have   anticipated   because   the  



superior  court's  interpretation  of  the  relevant  statutes  was  a "change  in law."   Because  



this   imposition   of   liability   is   linked   to   an   identified   property   interest  and   it   was  



accomplished  for  a  public  purpose,  Williams  argues  it  constitutes  a  compensable  taking.  



                   Williams's argument fails because it continuously characterizes the superior  



court's  interpretation  as  a  "change  in  the  law,"  when  it  is  not.   Williams  merely  disagrees  



with   the   interpretation   and   the   factual  basis   for   concluding   sulfolane   is   hazardous.   



          135      See  Hagen   v.  Strobel,   353   P.3d   799,   805   (Alaska   2015).   Furthermore,  



"eve-of-trial"  is  a  misleading  portrayal o             f  the  court's  actions.   The  court i  nformed  the  

parties  eleven  days  before  trial  and  approximately  five  weeks  before  the  close  of  trial  

how  it  planned  to  interpret  the  statute.   Trial  courts  are  under  no  obligation  to  issue  such  

memoranda  about  tentative  interpretations  of  the  law  ahead  of  trial,  and  doing  so  could  

only  have  assisted  Williams  in  preparing  its  case.

Similarly,   Williams   mischaracterizes   DEC's   communications   as  having   previously  



"expressly advised Williams that sulfolane was not a concern" but  now  determining it  



to   be   a   hazardous   substance.     As   discussed   above,   the   superior   court   made   factual  



findings  that  DEC  never  expressly  authorized  the  releases,  and  these  findings  are  not  



                           138  

clearly erroneous.              Finally  we note that Williams's irresponsible waste management  



and   sulfolane   releases   are   not   conduct   linked  to   "reasonable   investment-backed  



                                                                                    139

          138       Because  there  was  no  "change  in  law"  and  no  retroactive  liability  imposed  



here,  we  need  not  reach  the  arguments  of  Williams  and  the   State  concerning  whether  

retroactive   liability  under the  hazardous   substance   statute   effects   an  unconstitutional  

taking.

costs.       The  superior  court  determined  that  the  Purchase  Agreement  terms  barred  Flint  



Hills's claim  for indemnification because it had contributed to the sulfolane pollution,  



but  that  Flint  Hills  could  seek  contribution  pursuant  to  AS  46.03.822(j).  



                   Williams   disputes   the   superior   court's   interpretation   of   the   Purchase  



Agreement.   It first argues that Flint Hills assumed responsibility for the offsite sulfolane.   



Williams  also  contends  that  the  Purchase  Agreement's  indemnification  provision  is  the  



sole remedy  available  to  Flint  Hills  and  therefore  the  superior  court erred by  allowing  



statutory   contribution.     Williams  also  argues   that   any   award   against   it   -   whether  



through  indemnity  or  contribution  -  is  subject  to  the  Environmental  Cap  negotiated  in  



the  Purchase  Agreement.   Because  the  superior  court  did  not  err  when  it  interpreted  the  



parties'  allocation  of  liabilities  and  the  remedies  in  the  Purchase  Agreement,  we  affirm  



the  court's  determinations  regarding  Flint  Hills's  claims  against  Williams.  



                   1.	      Overview  of  the   Purchase   Agreement's   indemnification   and  

                            remedies  provisions  

                  Article   X142  

                                     of   the   Purchase   Agreement   contains   detailed   provisions  



regarding   financial   liability   between  the   parties   for   litigation   or   damages   incurred  



following the purchase.   Article X cross-references Section 10.2(a)(iv) of the "Disclosure  



Schedule"   appended   to   the   Purchase   Agreement.     That   section   of   the   Disclosure  



Schedule,  entitled  "Known  Environmental  Matters,"  begins  with  a  sentence  fragment  



stating, "Any and all costs of clean-up, monitoring, corrective actions and compliance  



         141       AS  46.03.822(j)  enables  liable  parties  to  "seek  contribution  from  any  other  



person  who  is  liable  under  (a)  of  this  section."   To  resolve  a  claim  for  contribution,  "the  

court   may   allocate   damages   and   costs   among   liable   parties  using   equitable   factors  

determined  to  be  appropriate  by  the  court."  



         142       The  Purchase  Agreement  refers  to  articles  using  Roman  numerals  but  

                                                                                                                    

sections within using ordinary Arabic numerals.  Thus it refers to the article as "Article

 contamination was caused by migration of a pollutant that had originated onsite and was  



                                          

 disclosed in the Schedule.

 not explicitly refer to offsite contamination, and the court concluded that the intent of the  



                                                                                                                                 

 parties was that Flint Hills would assume liability for the sulfolane located onsite at the  



              

 time of purchase.  



                                                                                                                                

                     Williams  argues  that  the  court  misconstrued  the  plain  language  of  the  



                                                                                                                           

 Agreement  when  it  concluded  that  Flint  Hills  had  not  assumed  liability  for  offsite  



                                                                                                                         

 sulfolane.        First,  Williams  claims  the  court  incorrectly  concluded  that  the  contract  



                                                                                                                            

 distinguished onsite/offsite sulfolane and that  Section  10.2(a)(iv)(A) excluded offsite  



                                                                                                                            

 matters.  Williams argues that subsection (A) in fact applies to both onsite and offsite  



                                                                                                                                  

 conditions, because  it refers to conditions "at, on or under  or arising, emanating, or  



                                                                                                                     

flowing from  any of the Assets or from  the property."  It argues that "arising, emanating,  



                                                                                                                            

 or flowing from" would be superfluous if it related solely to onsite conditions, which  



                                                                -70-                                                         7658
  


----------------------- Page 71-----------------------

would  have  been  properly  encapsulated  by  "at,  on  or  under."   Similarly,  Williams  points  



to  the  broad  definition  of  "Environmental  Condition"  in  the  contract  -  "any  condition  



existing  on,  at  or  originating  from ,  each  property"  -  to   support  its  contention that  a  



disclosed   substance   might   migrate   offsite   yet   remain   part   of   Flint   Hills's   assumed  



responsibilities.    Second,  Williams   argues that  the   superior   court  erred  by  relying   on  



extrinsic  evidence  to  assist  with  the  interpretation  of  the  Purchase  Agreement.   Williams  



claims  that  reference  to  extrinsic  evidence  violated  Texas  contract  law  governing  the  



agreement.  



                   We  conclude  that  the  superior  court's  inferences  about  the  parties'  intent,  



based   on   extrinsic   evidence,   were   supported   by   substantial   evidence.    We   further  



conclude,  from  these  inferences  and  from  our  de  novo  review  of  the  contract  language,  



that  the  superior  court did not  err  by  determining  Williams  retained  liability  for  offsite  



sulfolane.   



                   3.	      The  superior  court  did  not  err  by  concluding  Williams  retained  

                            responsibility  for  offsite  sulfolane.  



                   We apply Texas  law  to  the  interpretation  of  the  Purchase  Agreement;  the  



parties   chose   Texas   law   to   govern   the   Agreement   and   neither   party   disputes   its  



                       148  

application  here.

----------------------- Page 72-----------------------

                   The  language  in  the  Purchase  Agreement  is  ambiguous.   On  one  hand,  its  



definition  of Environmental Condition  and  the language about such  conditions  in  Section  



10.2's  indemnification  provisions appear  to  be  extremely  broad;  they  could  therefore  



apply  to  both  onsite  and  offsite  pollution.   The  carve-out  for  sulfolane  in  the  Disclosure  



Schedule  would,  by  extension,  include  sulfolane  pollution  that  had  migrated  offsite  prior  



to  the  purchase  date.   On  the  other  hand,  the  breadth  of  Section  10.2(a)  might  apply  only  



to   Williams's   retained   liabilities,   while   Flint   Hills's   assumed   liabilities  are   instead  



narrowly   tailored   to   those   "matters   set   forth"   in   the   Disclosure   Schedule   only   for  



conditions  "at"  the  property.  In that case, Williams's reference to the  broad  definition  



of "Environmental  Condition" and the language of "arising, emanating,  or  flowing from"  



would   not   apply   to   Flint  Hills's   assumed   responsibilities.     Indeed,   the   Disclosure  



Schedule    refers    to    the    matters    set    forth    therein    as   "contamination"    and    not  



"Environmental Conditions," possibly supporting this narrower construction.   (Emphasis  



added.)   In  other  words,  assuming  responsibility  for  "existing,  known  contamination  at  



the  Real  Property"  would  not  necessarily  include  assuming  responsibility  for  the  effects  



arising  or  emanating  from  such  contamination  off  the  real  property.   



                   Because  the  contract  language  is  ambiguous,  it  was  proper  for  the  superior  



court  to  resort  to  extrinsic  evidence.   Though  Texas  law  places  greater  restrictions  on  the  



          148      (...continued)  



                   We   see   no   obvious reason   that   applying   Texas   law   to   this   case   would  

conflict with Alaska's choice of law approach, which follows the Second Restatement  

                                                                                                                 

of Conflicts.  See Peterson v. Ek, 93 P.3d 458, 464 n.11 (Alaska 2004).  As we discuss  

                                                                                                               

below, it is unlikely that the resulting interpretations would differ under either Alaska's  

                                                                                                                  

or Texas's interpretive  approach,  as both  would  admit the  extrinsic evidence which

975   (quoting  Est.  of Polushkin  ex  rel.  Polushkin  v.  Maw,   170  P.3d   162,   167   (Alaska  

2007)).   The  court  need  not  initially  determine  that  the  disputed  language  is  ambiguous  

to   consider   extrinsic   evidence;  instead,  the  court   can  look  holistically   at  the  disputed  

language,   other   language   in   the   contract,   relevant   extrinsic   evidence,   and   case   law  

interpreting   similar  provisions.   Id. ;  see   also  Nautilus  Marine  Enters., Inc.   v.  Exxon  

Mobil   Corp.,   305   P.3d   309,   316   (Alaska   2013)   ("We   have   expressly   rejected   the  

'artificial  and  unduly  cumbersome'  two-step  process  used  in  other  jurisdictions  in  which  

'resort   to   extrinsic   evidence   can   take   place   only   after   a   preliminary   finding   of  

ambiguity.' "  (quoting  Alyeska  Pipeline  Serv.   Co.  v.   O'Kelley,  645  P.2d  767,  771  n.1  

(Alaska   1982))).   But  extrinsic  evidence  cannot  be  used  to  add  or  contradict  contract  

terms.   See  Froines  v.   Valdez  Fisheries  Dev.  Ass'n ,  75  P.3d  83,  87  (Alaska  2003).  



                   Texas  law  is  more  restrictive.   It  indicates  that  a  court's  "primary  objective  

is  to  ascertain  and  give  effect  to  the  parties'  intent  as  expressed  in  the  instrument."   URI,  

Inc.  v.  Kleberg  Cnty.,  543  S.W.3d  755,  763  (Tex.  2018)  (emphasis  added).   "Objective  

manifestations   of   intent   control,"   and   therefore   courts   should   interpret   language  

according to its  " 'plain, ordinary,  and generally  accepted meaning'  unless the instrument  

directs   otherwise."   Id.   at   763-64 (quoting   Heritage   Res.,  Inc.   v.  NationsBank,   939  

S.W.2d   118,   121  (Tex.   1996)).   However,  the  Texas  Supreme  Court  has  explained  that  

the  meaning  of  words  often  "turns  upon  use,  adaptation  and  context."   Id.  at  764  (quoting  

Heritage  Res., Inc., 939   S.W.2d   at   121).    This   context   is   not  just   gleaned   from   the  

language  and  structure  of  the  contract  itself,  but  also  from  the  "circumstances  present  

when  the  contract  was  entered."   Id.  (quoting  Columbia  Gas  Transmission  Corp.  v.  New  

Ulm  Gas,  Ltd.,  940  S.W.2d  587,  589  (Tex.   1996)).   Thus,  while  a  court  cannot look to  

extrinsic  evidence  to  add  or  modify  contract  terms  -  i.e.,  to  introduce  solely  subjective  

intent  that  has  not  been  manifested   objectively   in  the   contract  -   it   can  use   extrinsic  

evidence  where  the  contract  language  is  inherently  ambiguous.   Id.

circumstances  that  inform,  rather  than  vary  from  or  contradict,  the  contract  text."                     As  



we  discuss  below,  we  conclude  that  the  superior  court  adhered  to  Texas  contract  law's  



requirements  when  it  used  extrinsic  evidence  to  resolve  the  ambiguities  of  Article  X.   



                  Flint  Hills  Resources'  Alaska  President  Allen  Lasater  testified  that,  based  



on  his  understanding  of  the  parties'  intent  at  the  time  of  contracting,  Flint  Hills  did  not  



assume   responsibility   for   offsite   contamination.    He   stated   that   there   was   no   offsite  



sulfolane  contamination  then  "known"  and  thus  it  was  not  included  in  the  Disclosure  



Schedule.   Lasater  essentially  equated  unknown to  undisclosed,  and  therefore  liability  



for  those  unknowns   "remained  with Williams."   He   explained  that  this  was   a  logical  



intent  because  Flint  Hills  needed  to  know  the   extent   of  pollution  in   order  to   agree  to  



continue   running   the   refinery's  pollution   remediation   system   consistent   with   DEC's  



compliance  orders.  



                  Williams  representative  Randy  Newcomer  qualified references to known  



conditions  as  "known  conditions  which  were  primarily  onsite."   (Emphasis  added.)   He  



stated  that  Flint  Hills  took  responsibility  for  "known  cleanup"  of  "known  contaminants"  



as  described  in  the  Disclosure  Schedule  as  of  the  Effective  Date,  after  which  Flint  Hills  



was responsible for  additional pollution  occurring  on- and offsite during their  ownership.   



Williams  thus  remained  responsible  for  the  unknown  conditions  offsite  "caused  .  .  .  by  



Williams  during  its  ownership."   Upon  further  questioning,  Newcomer  stated  that  there  



was  a  "your  watch/my  watch  kind  of  .  .  .  thing"  specifically  for  offsite  contaminants.   He  



explained  that  if  a  known  contaminant  offsite  caused  damage  before  the  Effective  Date,  



Williams  would  take  responsibility,  but  "[i]f  it  was   something  that  Flint  Hills caused  



during   their   ownership   of   the   [r]efinery,"   then   Flint   Hills   assumed   responsibility.   



Newcomer  admitted  that,  as  he  understood  the  contract,  Williams  would  be  obligated  to  



         151      Id.  at  767  (quoting  Hous.  Expl.  Co.  v.  Wellington  Underwriting  Agencies,  



Ltd.,  352  S.W.3d  462,  469  (Tex.  2011)).

indemnify Flint Hills for the portion of sulfolane that had migrated off the property when  



                                                                                                                           

Williams owned the refinery.  But he said that further migration or contamination offsite  



                                                                                                        

after the Effective Date would be the responsibility of Flint Hills. On cross-examination,  



                                                                                                                            

Newcomer  emphasized that  liabilities were  defined by  their  known/unknown  status  



                  

rather than onsite/offsite.  



                                                                                                                               

                    The Williams Companies Senior Vice President Phillip Wright, who was  



                                                                                                                                 

involved in the refinery sale negotiations, similarly testified that "as a general matter, we

would  be  liable  for those  damages  .  .  . and they  would  retain  liability  for  anything

known  characterized  contamination."                          He  testified  that  it  was  Williams's  intent,  



                                                                                                                                

expressed through the language of the contract, that if the sulfolane migrated off the  



                                                                                                                             

property, it was Flint Hills's responsibility.  He further added that "[i]t wouldn't have

reflects  that  intent.  



                   4.	      The   superior   court   did   not   err   by   concluding   that   Flint   Hills  

                            could  pursue  contribution.  



                   The   superior   court   concluded  that   contractual   indemnification   was   not  



available  to  Flint  Hills  because  it  had  "caused  or  contributed"  to  the  offsite   sulfolane  



contamination.   And  the  court  concluded  that  because  indemnification  was  not  available,  

Section   10.4(b)'s  Environmental  Cap  did  not  apply.152  

                                                                              But  the  court  determined  that  



Flint  Hills  could  pursue  contribution  from  Williams  under  AS  46.03.822(j).   Exercising  



                                                                                                     153  

its   discretion   to   allocate   equitable   responsibility   among   the   parties,                    the   court  



determined  that  Williams  was  required  to  contribute  $52.5  million  to  Flint  Hills's  offsite  



response  costs,  reflecting  its  equitable  allocation  of  75%  of  costs  to  Williams.   The  court  



awarded   $51.4   million   for   offsite   sulfolane   and   $1.17   million   for   onsite   PFAS  



contamination,  plus  prejudgment  interest  on  both.  



                  No  party  disputes  the  court's  determination  that  Flint  Hills  was  barred  from  



pursuing  contractual  indemnity.   However,  Williams  contends  that  the  superior  court's  



assessment   of   damages   for   offsite   sulfolane   was   erroneous   because   it   exceeded   the  



Environmental  Cap  of  $32  million.   Williams  claims  that  the  Environmental  Cap  should  



apply  to  all  forms  of  damages,  including  statutory  damages  and  contribution  allocations,  



         152       In   Flint    Hills    I,    we    determined    that    indemnification    claims              for  



environmental  liabilities  would  be  subject  to  the  Cap.   377  P.3d  at  976.  



         153      See  AS  46.03.822(j)  ("[T]he  court  may  allocate  damages  and  costs  among  



liable  parties  using   equitable   factors  determined  to  be   appropriate  by  the   court.");  cf.

rather  than  only  to  contractual  indemnification  damages.                   Williams  further  argues  that  



statutory   contribution   is  not   available  to  Flint  Hills  because  the  Purchase  Agreement  



made   indemnification   the   exclusive   remedy   for   environmental   damages   claims.   



Williams  argues  that  by  failing  to  properly  construe  the  exclusive  remedies  provision  in  



Section   10.5,  the  superior  court  "allowed  Flint  Hills  to  achieve  an  end-run  around"  the  



indemnity  bar.   Williams  asserts  that,  because  money  damages  are  not equitable  relief  



allowable  under   the   Purchase   Agreement   and  because  we   characterized   contribution  



damages  under  AS  46.03.822(j)  as  a  legal  claim  in  Flint  Hills  I,  contribution  should  be  



barred  by  the  Purchase  Agreement.   We  disagree.  



                  The  Purchase  Agreement  at  Section  10.2(a)  provides  that  Williams  would  



indemnify  Flint  Hills  "(iv)  except  to  the  extent  that  Damages  are  caused  or  contributed  



to  by  [Flint  Hills's]  operations,  actions  or  omissions  after  the  Effective  Time."   The  most  



natural  reading  of  this  language  and  the  reading  best  supported  by  trial  testimony  is  what  



the  superior  court  first  concluded:   "reflecting  the  joint  'my  watch/your  watch'  concept  



for  liabilities,  the  parties'  cross-indemnity  provisions  included  language  clarifying  their  



obligations   to   be   limited   to   their   own   causes   and   contributions  of   Environmental  



Conditions,   excluding   reimbursement  and  exempting   each   from   holding   the   other  



harmless  for  contributions  or  conditions  caused  by  the  other's  conduct."   However,  the  



superior   court   later   determined   that   because   Flint   Hills   contributed   to   some   of   the  



sulfolane  pollution during the period it operated the  refinery, as  a  matter  of  law  "[t]his  



exception precludes contractual indemnity for sulfolane contamination."   Because neither  



Williams nor  Flint Hills challenges  the superior  court's interpretation, we do not consider  



         154      Williams  also  argues  that  the  superior  court  made  two  other  errors  when  it  



interpreted  the   Cap:  the   court   determined  that  insurance  proceeds  paid  to  Flint  Hills  

were  not  relevant  to  the  Cap,  and  it  declined  to  enforce  the  Cap  for  public  policy  reasons.   

Because  we  conclude that the  Cap does not apply to the contribution claim, we do not  

address  these  arguments.  

                                                        -77-                                                   7658

 it  further.  



                    We  agree  with  the  superior  court  that,  because  Flint  Hills  cannot  pursue  



 indemnification  under  the  Purchase  Agreement,  the  Environmental  Cap  does  not  apply.   



 Section   10.4's   "Limitations   on   Indemnification"   states   in   subsection   (b)   that   "the  



 maximum amount  of  indemnifiable  Damages" arising  out  of Sections 10.2(a)  and  (b)  that  



 can be  recovered  by  "Indemnified  Parties"  is  a  Cap "with respect to any and all claims  



for  indemnity."  (Emphasis  added.)   This  language  makes  clear  that  the  Cap will  apply  



 only   to    indemnification    claims.     Furthermore,    Section    10.5   provides   that   "the  



 indemnification  provisions  of  this  Article  X  shall be  the  sole  and exclusive  remedy  of  



 each  Party,"   "[e]xcept   for   .   .   .   equitable  relief."    (Emphasis   added.)    The  Agreement  



 makes  clear  that  both  parties  understood  equitable  relief  is  not  governed  by  the  terms  of  

                                                     155   It  was  not  error  for  the  court,  when  making  

 limitation   in   their   private   contract.                                                                      



 contribution allocations, to take into account the parties' intended contractual allocations  

                                                                                                                



                                                                                                                            156

                    Finally,  the  superior  court  did  not  err  by  concluding  that  Flint  Hills  could  



pursue  statutory  contribution  under  AS  46.03.822(j).   In  Flint  Hills  I,  we  referred  to  Flint  



Hills's   indemnification   claim   and   its   statutory   contribution   claim   under   subsection  



.822(j)  as  "legal  claims,"  in  contrast  with  its  "equitable  claims"  for  declaratory  judgment  



                                       157  

and  specific  performance.                 We  did  not,  however,  reach  the  question  whether  statutory  



contribution   constitutes   a   legal   or   equitable   remedy.     Contribution  is  an   equitable  



            158                                                                                           159  

remedy.           This  is  so  regardless  of  whether  it  is  provided  for  by  statute.                   Thus  a  claim  



for  statutory  contribution  is  not  barred  by  the  Purchase  Agreement's  exclusive  remedies  



provision.  



                    Williams's  argument  that contribution  achieves  an  "end-run  around"  the  



indemnity  bar  is  unpersuasive.   The  parties   agreed  they  would   still  be   able  to  pursue

equitable   relief,   "including   injunctive   relief   or   specific   performance."     The   word  



"including"  indicates  these  examples  are  illustrations  rather  than  an  exhaustive  list  of  



allowable  equitable  relief.   Contribution  falls  squarely  into  relief  allowed  even  under  the  



parties' own contractual arrangement.   And Williams misconstrues our previous decision  



when  it argues that  contribution  provides  a  duplicative and  thus ina                 ppropriate  remedy  



                                                160  

once  indemnification  is  unavailable.              In  Flint  Hills  I,  we  denied  Flint  Hills  declaratory  



relief  and  specific  performance  because  we  determined  that  it  still  had  an  adequate  legal  



         160      We  do  not  decide  whether  contribution  would  have  been  available  absent  



the  parties  explicitly  permitting  the  pursuit  of  equitable  remedies.   We  have  recognized  

a  common  law  contribution remedy,  McLaughlin,   137  P.3d  at  275-79,  and  a  statutory  

contribution  remedy  in  the  hazardous  substance  context,  AS  46.03.822(j).   But  Alaska  

does  not  have  a  general  contribution  statute,  such  as  the  proposed  Uniform  Contribution  

Among  Tortfeasors  Act  of  1955,  that  discusses  the  relation  between  indemnification  and  

contribution.     And   even   CERCLA   case   law,   though   generally   indicating   that   an  

indemnification agreement  encompassing  CERCLA liability between responsible parties  

will  control,  is  not  always  clear  about  whether  such  an  agreement  displaces  contribution  

altogether  or  controls  equitable  allocation  in  a  contribution  action.   See,  e.g.,  Fina,  Inc.  

v.  ARCO ,  200  F.3d  266,  273-74 (5th  Cir.  2000)  (allowing  claim  for  contribution  only  

after  concluding  that  parties'  indemnification  provision  did  not  cover  CERCLA  claims);  

Kerr-McGee  Chem.  Corp.,  14  F.3d  at  326  (finding  indemnity  agreement  between  parties  

remained   applicable   in   CERCLA   action,   but   that   result   of   indemnification   and  

contribution would have been  identical  and  therefore  declining  to  reverse contribution  

award;  also  indicating  that  equitable  allocation  informed  by  indemnification  agreement  

could  be  modified  depending  on  parties'  ability  to  pay  to  avoid  shifting  cleanup  costs  

onto  public);  Beazer  E.,  Inc.  v.  Mead  Corp.  (Beazer  I),  34  F.3d  206,  208-10,  218-19,  219

447  n.20  (revisiting  issues  between  parties  and  interpreting  Kerr-McGee  to  mean  that

remedy  through  indemnification  or  contribution  -  even  if  some  of  those  legal  remedies  



                                                                       161  

might  be  time-barred  by  the  statute  of  limitations.                  We  noted  that  Flint  Hills's  equitable  



claims   sought   identical   relief   to   its   legal   claims,   since   its   requests   for  declaratory  



judgment  and  specific  performance  essentially  asked  the  court  to  order  Williams  to  pay  



the   same   damages   Flint   Hills   had   requested   in   its   indemnification   and   contribution  

claims.162  

                We   did  not   conclude  in  Flint  Hills  I  that  indemnification   and   contribution  



were  duplicative  remedies  or  constituted  identical  relief.  



                    Unlike  its  claims  for  declaratory  relief  and  specific  performance  vis-à-vis  



its  claims  for  indemnification  and  statutory  contribution, Flint  Hills's  contribution  claims  



are   not   duplicative   of   its   legal   indemnification   claims.    If   available,   indemnification  



might  have  enabled  Flint  Hills  to  recover  entirely  for  the  offsite  sulfolane  pollution  that  



Williams  caused  or  contributed  to  prior  to  the  refinery  purchase,  without  any  equitable  

                                                                                     163     By  contrast,  statutory

The parties' indemnification agreement, although inapplicable, served to inform the court

determination.  



                  For   these   reasons, the   contract   language   expressly   allows   the   statutory  



contribution  remedy  and  doing  so  does  not  inappropriately  provide  Flint  Hills  an  "end- 



run  around"  its  contractual  arrangements  or  inappropriately  award  an  equitable  remedy  



when a legal one  was potentially available.  The superior court did not err by  granting  



Flint  Hills  statutory  contribution  from  Williams  under  AS  46.03.822(j).  



                  5.	      The     superior       court's     contribution         allocations       were     not  

                           erroneous.  



                  A    party    liable    for    the    release    of   a    hazardous      substance    under  

AS  46.03.822(j)  "may  seek  contribution  from  any  other  person  who  is  liable."164  

                                                                                                          During  



a  statutory  contribution  proceeding,  "the  court  may  allocate  damages  and costs among  

liable  parties  using  equitable  factors  determined  to  be  appropriate  by  the  court."165  



                  After   Flint Hills   sought   contribution   from   Williams,   the   superior   court  



made  a  series  of  findings  regarding  Flint  Hills's  contribution  claims.   In  relevant  part,  the  



court  found:   "Williams  is  strictly  liable,  jointly  and  severally,  under  AS  46.03.822  for  



hazardous   substance  releases   as   an   owner   and   operator   of  the   [refinery]";   "the  harm  



caused   by   Williams['s]   sulfolane   releases   is   not   divisible   or   reasonably   capable   of  



apportionment"  and  thus  Williams  "is  jointly  liable  for  the  entire  amount  of  response  



costs."    Based   on   consideration   of   many   equitable   factors   -   including   contractual  



indemnity  clauses,  proportions  of  sulfolane  releases  attributable  to  each  party,  the  degree  



of  cooperation  by  each  party,  and  promptness  of  reporting  sulfolane  in  the  groundwater   



-  the  court  found  "Williams  is  responsible  for  75%  of  the  [offsite]  sulfolane  response  



costs,   while   Flint   Hills   is   responsible   for   25%   of   the   costs,   and   the   State   is   not

responsible  for  any  of  the  costs."             



                   Williams   appeals   the   superior   court's   statutory   contribution   allocation  



under   AS   46.03.822(j),   arguing  the   court   erred  by   (1)   allocating   anything   for   offsite  



sulfolane  to  Williams  because  the  parties  "had  allocated  full  responsibility  for  sulfolane  



to   Flint   Hills   under   the   Agreement";   (2)   failing   to   properly   consider   DEC's   non- 



regulation   of   sulfolane   prior   to   2004;  (3)   penalizing   Williams   for   defending   itself;  



(4)   "failing  to   allocate  responsibility  to  the   State   and  ignoring  Williams['s]   equitable  



estoppel  and  laches  defenses";  and  (5)  "failing  to  allocate  responsibility  to  the  City."  



                            a.	       The  court  did  not  err  by  allocating  statutory  contribution  

                                      for  offsite  sulfolane  to  Williams.  



                   We  have  affirmed  the  superior  court's  conclusion  that  Williams  retained  



responsibility for sulfolane that was offsite at the time of the Purchase Agreement and  



that  Flint  Hills  could  recover  through  statutory  contribution  in  the  absence  of  contractual  



indemnification.   The  court  therefore  did  not  err  by  allocating  responsibility  to  Williams  

under  the  contribution  provisions  of  AS  46.03.822(j).167  



                            b.	       The  superior  court  adequately  considered  DEC's  earlier  

                                      non-regulation  of  sulfolane  when  it  allocated  damages.  



                   Williams  argues  that  the  superior  court  erred  when  it  "failed  to  compare  the  



relative   'culpability'   of   Williams   and   Flint   Hills   given   the   very   different   regulatory  



environments  in  which  each  operated  the  refinery."   Namely,  because  sulfolane  was  not  



regulated  as  a  hazardous  substance  when  Williams  released  it,  Williams  argues  the  court  



erred  by  not  reducing  Williams's  culpability.   Williams  relies  primarily  on  two  cases  for  



          166      The court did not allocate  any  costs  to  the  City  of North Pole, which was  



not  a  party  at  the  trial.

which  party  'knew  or  should  have  known'  of  the  contamination  and  which  party  'had  the  

ability to control the [cause]'  at the  time."169  Williams argues that, had sulfolane been  



regulated  before   the   Purchase   Agreement,   it   would have  been   able   to   keep   it   onsite  



because  it  "kept  all  regulated  contaminants  onsite  during  its  tenure."    



                   Superior   courts   have   broad   discretion   over   which   equitable   factors   to  

consider  when  allocating  costs  under  both  CERCLA  and  AS  46.03.822.170  

                                                                                                        A  court  may  



choose  to  reduce   a  party's damages  according  to  the  party's  practices   and  prevailing  



circumstances  at  the  time,  but  it  is  not  required  to.   And  as  the  State  points out,  neither  



Boeing  Company  nor  Oakly  Enterprises  supports  Williams's  position  in  this  case.   Even  



though  sulfolane  was  not  yet  regulated  as  a hazardous  substance,  it  would  have  been  a  



pollutant   under   AS   46.03.900(20)   and   thus   its   unpermitted   releases   were   prohibited  



under  AS  46.03.710.   As  Williams  conceded  at  trial,  releasing  sulfolane  regardless  of  its  



official   status   as   a   hazardous   substance   was   prohibited   by   law   -   a   fact   that   counts  



against  Williams  rather  than  in  its  favor.   The  record  demonstrates  that  Williams  knew  



about the sulfolane releases during its tenure at the refinery  due  to its  own  negligence,  



but failed to address the ongoing releases.  Williams k                     new sulfolane was at least toxic  



if not  "hazardous."   Yet the "care" that Williams exercised included storing sulfolane-

containing  waste  in  a  leaky,  decommissioned  lagoon,  some  of  whose  many  holes  were  



crudely   "patched"   by   nailing   two-by-fours   to   the   liner.     Williams   also   unilaterally  



stopped  the  monitoring  that  DEC  requested  to  help  identify  and  address  the  source  of  the  



sulfolane  leaks.   That  behavior  was  neither  typical  nor  allowed  at  the  time,  and  Williams  



knew   of   and was  in  control  of  the  cause  of  the  contamination,   supporting  the  court's  



decision  to  impose  statutory  contribution  against  Williams.  



                            c.	       The    superior    court    did    not    penalize    Williams    for  

                                      "defending  itself."  



                   Williams  argues  that  the  court  erred  because  its  "allocation  expressly  took  



into  account  Williams'[s]  alleged  'recalcitrance'  and  'refusal  to  assist'  DEC."   Williams  



argues  it  was  penalized  for  defending  itself.   Williams  contends  it  was  within  its  rights  



to  refuse to  provide alternative  water  and  to  indemnify  Flint  Hills,  and  claims  it  would  

be  unconstitutional  to  penalize  it  for  doing  what  the  law  plainly  allows  it  to  do.171  

                                                                                                                     



                   The State quickly  and  correctly dismisses this argument by  pointing  out  that  



"[a]  party   may  be   'within   its  rights'   to  refuse  to   act  until   ordered  by a   court,  but   its  



choices  can still weigh against it in equity."  Courts often  consider  the  extent  to which  



                                                                    172  

parties  cooperate  with  regulators  in  this  context.                  



          171      We agree with the  State that  none  of the cases Williams  cites for support   



contradict   the   assertion   that   a  party's  refusal   to   act   can   "weigh   against   it   in   equity."   

Williams relies  for  support  on  an incomplete quote from a dissent, without identifying  

it   as   such,  but   omits   the   following   paragraph   of   that   dissent,   which   acknowledges  

"CERCLA   strongly   incentivizes   voluntary   compliance"   and   refers   to   a   case   that  

recognizes  the  court's  ability  to  impose  fines  when  a  responsible  party  willfully  fails  to

                  Williams  asserts  in  reply,  without  support,  "that Williams  cooperated  in  the  



initial   investigation"   and   that  "six   years   after   the   refinery's   sale,   Williams   was  



participating   and   willing   to  continue   doing   so,   until   the   State   abruptly   stopped  



investigating  and   sued."   Our  review  of  the  record  confirms  that  Williams  conducted  



groundwater   sampling   for   sulfolane   for   about   a   year   before   stopping   the   sampling  



without   having   identified   the   source   of   the    sulfolane   leak,   contrary   to  DEC's  

instructions.173  And Williams  attended meetings with DEC  and offered to  pay for and  



conduct  certain  modeling,  though  it  did  not  give  the  models  to  DEC.   But  Williams  does  



not  point  to  anything  in  the  record  indicating  that  it  cooperated  with  DEC.   Williams  has  



not  challenged  the  superior  court's  findings  of  fact  on  this  issue,  including  its  extensive  



findings   showing   an   overwhelming   level   of   inaction   by   Williams   even   after   it   had  



received  notice  in  2010  that  DEC  would  be  treating  sulfolane  as  hazardous.   The  court  



did  not  abuse  its  discretion  by  allocating  costs  against  Williams  in  part  for  its  lack  of  



cooperation.  



                            d.	      The    superior    court    did    not   err    by    not    allocating  

                                     responsibility   to   the   State   or   by   ignoring   Williams's  

                                     equitable  defenses.  



                  Williams  argues   that   because   the   State   admitted   to   being   a   "liable  



landowner  under  AS  46.03.822(a)"  as  an  owner  of  the  refinery  lands,  the  court  erred  by  



not  allocating   some  responsibility to the   State  under  AS  46.03.822(j).   Williams  also  



argues  that   "the   court   should  have   allocated   some   .822(j)  responsibility  to  the   State"  



based  on  laches  and  equitable  estoppel.

                   Williams  cites  FDIC  v.  Laidlaw  Transit,  Inc.                     for  support that  the  State  



should  be  allocated  costs  for  sulfolane  contamination,  but  that  case  does  not  support  its  



argument.    In   Laidlaw   we   recognized   that   cleanup   costs   need   not   "be   borne   by   all  



potentially   responsible   parties   equally"   and   that   courts   can   "distinguish   among  



                                                                                         175  

potentially  responsible  parties   to   avoid   inequitable  results."                        And   AS   46.03.822(j)  



expressly grants discretion  to  "allocate  damages  and  costs  among  liable  parties  using  



equitable   factors   determined   to   be   appropriate   by   the   court."    Williams's   argument  



amounts  to  mere  disagreement  with  how  the  court  weighed  these  equitable  factors.   



                   When  it  found  that  the  State  was  without  fault  as  a  landowner,  the  superior  



court   reasoned   that   "[n]o   persuasive   evidence   was   presented   at   trial  to  support   an  



equitable  allocation"  to  the  State.   Williams  points  to  several  factors  it  suggests  indicate  



the  State's  culpability.   For  instance,  it  asserts  that  the  State  had  a  "but-for  causal  role  in  



allowing   the   sulfolane   to   remain   in   the   ground   throughout   Williams'[s]   tenure."   



Williams seems to  argue  that, because  it  notified DEC of the sulfolane release in 2001   



and  DEC  told  Williams  only  to  keep  tracking  sulfolane  through  sampling  because  it  was  



not  then  a  regulated  contaminant,  Williams  had  no  obligation  to  clean  it  up.   But  as  early  

as  November  2000  a  representative  from  the  Department  of  Natural  Resources176  met  

                                                                                                                         



with Williams and DEC to discuss the adequacy of Williams's spill prevention efforts  

                                         



and the preparation of a characterization and corrective action plan.  In that meeting,  

                                                                                                                  



DNR told Williams that it might be in default on its lease because of the spills.

releases   by   allowing   Flint   Hills   to   turn   off   its   pumping   system   in July   2017,   which  



Williams claims "caus[ed] the sulfolane to migrate offsite."   Although the State did allow  



Flint  Hills  to  turn  off  the  pumping  system,  sulfolane  had  already  been  detected  offsite  in  



October  2009.   Furthermore,  the  court  expressly  considered  this  factor  and  found  it  to  



be  outweighed  by  Williams's  "other  negative  conduct,"  such  as  "mismanagement  .  .  .  of  



its  waste  fluid  treatment  and  disposal  systems"  and  "cessation  of  testing  for  sulfolane  



sources  on  the  [R]efinery  property."   Williams  does  not  argue  that  the  court  erred  when  



it  weighed  this  fact  about  Flint  Hills  turning  off  the  pumps  in its equitable  allocation  



decision.   We  are  not  persuaded  the  court  erred  by  not  allocating  financial  responsibility  



to  the  State  as  a  landowner  under  these  circumstances.  



                   Williams   also   argues   that   the   superior   court   "inexplicably   ignored  



Williams'[s]  equitable  estoppel  defense  and  reasonable  reliance  on  the  State's  repeated  

written  affirmations  that  sulfolane  was  not  regulated  and  could  be  left  in  the  ground."177  

                                                                                                                          



Williams  alleges  that  the  court  "previously  found  this  defense  to  be  relevant  to  allocating  



damages  under   .822(j)."    But   the   court previously   explained   that   equitable   defenses  



would   be   relevant,   if   at   all,   for   allocation   under  subsection   .822(j)   rather   than   for  



establishing liability under subsection .822(a)  because that would undermine  the strict  



liability  framework  of  the  hazardous  substance  statute.   And  in  any  case  the  court  did  not  



explicitly  find  that  Williams's  equitable  estoppel  defense  was  relevant  for   subsection  



.822(j)  allocation.   As  the   State  points  out,  Williams  does  not  provide  any  arguments  



undermining  the   court's  discretionary   decision  not  to  consider  Williams's  defense   of  



         177       "Equitable  estoppel  requires  proof  of  three  basic  elements:   (1)  'assertion  



of a  position  by  conduct or word,' (2) 'reasonable reliance thereon,' and (3) 'resulting  

prejudice.'   In  addition,  equitable  estoppel  'will  be  enforced  only  to  the  extent  that  justice  

so  requires.'  "   Beecher v   .   City  of   Cordova,  408  P.3d 1208, 1214  (Alaska  2018)  (first

equitable  estoppel.  



                   Williams   also   argues   that   laches  "should   have   comparatively   reduced  



Williams'[s]  responsibility  because"   in   earlier  proceedings   "the   superior   court   found  



laches  barred  Flint  Hills'[s]  claims  for  equitable  remedies  against  Williams  due  to its  



'unconscionable   delay'   in  addressing   sulfolane."     Williams   then   states,   somewhat  



misleadingly,  that  the  "factual  findings  upon  which  the  court's  laches  decision  was  made  



were  affirmed  on  appeal"  and  should  have  preclusive  effect.   We  earlier  agreed  that  Flint  



Hills "reasonably  should  have concluded 'long before May 10,  200[8]' that sulfolane had  



                                                                                   178  

migrated  beyond  the  sampling  disclosed  in  the  Agreement."                        But  we  explicitly  did  not  



reach  the  issue  of  Williams's l  aches  defense  on  Flint  Hills's  equitable  claims  because  

these  were  not  available  in  light  of  the  legal  remedies  available  by  contract  and  statute.179  

                                                                                                                            



Williams   also   challenges  the   court's   conclusion  that  Williams's   delayed  reporting   of  



discovering  sulfolane  in  the  groundwater  was  more  problematic  than  Flint  Hills's  nearly  



two-year  delay  in  drilling  monitoring  wells.   We  see  no  abuse  of  discretion  in  allocating  



more   responsibility   to   the   party   that   waited   five   years   to report its   discovery   that   a  



relatively  novel  solvent  had  leached  into  the  groundwater  than  to  the  party  that  delayed  



drilling  "recommended  monitoring  wells"  for  about  two  years.   



                            e.	       The   superior   court   did   not   err   by   failing   to   allocate  

                                      responsibility  to  the  City  of  North  Pole.    



                   Williams  next  argues  that  "[t]he  City  was  a  significant  source  of  sulfolane"  



and  the  court  should  have  allocated  responsibility  to  the  City.   The  court  did  not  rule  on  



the   City's   liability   and  prevented  Williams   from  presenting evidence   implicating  the  



City's  contribution  to  the  sulfolane  plume.

the cases in June  2019 the City was no  longer a party  to these proceedings.  While  the  



cases were  consolidated,  Williams  raised  a contribution  claim against the City, but  the  



court   dismissed   it   as   untimely.    Though   in   the   State's   suit   the   court   could   have  



considered  the  City's  culpability  as  an  equitable  factor  under  AS  46.03.822(j),  because  



Williams  is  "strictly  liable,  jointly and  severally"  under AS  46.03.822(a),  the  superior  



                                                                                                                      180  

court  did  not  abuse  its  discretion  by  failing  to  allocate  costs  to  an  absent  party.                          



                    Williams  also  attempts  to  appeal  the  deconsolidation  order.   The  Rules  of  



Appellate  Procedure  require  that  an  appeal  brief  contain  a  "short  conclusion  stating  the  



                                 181  

precise  relief  sought"             and  that  the  argument  section  contain  "the  contentions  of  the  



appellant   with   respect   to   the   issues   presented"   as   well   as   a   "heading   indicating the  

subject  matter"  for  "[e]ach  major  contention."182  Williams asks in its statement of issues  

                                                                                                                          



on appeal whether the superior court erred in deconsolidating the cases but does not  

                                                                                                                              



request that the deconsolidation be reversed on appeal, and omits any mention of the  

                                                                                                                              



order from its discussion heading. Williams claims it was prejudiced by deconsolidation,  

                                                                                                          



but  fails to challenge the court's detailed justifications  for deconsolidating the cases.  

                                                                                                                                    



Williams adds in a heading in its reply brief that the superior court "erred by sua sponte  

                                                                                                                         



deconsolidating the cases," but again fails to cite to a rule or case indicating how the  

                                                                                                                              



court erred. Williams waived its deconsolidation argument: we "consider as abandoned

                AFFIRM   the   superior   court's   conclusion   that   sulfolane   is   a   hazardous  



substance  under  AS  46.03.822(a);  



                AFFIRM  the  superior  court's  award  of  response  costs  under  AS  46.03.822  



to  the  State  and  Flint  Hills  for  Williams's  offsite  sulfolane  releases;  



                AFFIRM  the   superior   court's   award   of  natural  resource   damages  to  the  



State  for  the  loss  of  access  to  groundwater;  



                AFFIRM  the  superior  court's  interpretation  of  the  Purchase  Agreement's

contamination  issues  to  DEC;  and  



                AFFIRM  the  superior  court's  declaratory  relief;  but
