18 AAC 69.025. Plan of sampling techniques and analytical testing methods

(a) On or before March 1 of each calendar year, except in a calendar year in which a plan is valid for the calendar year under (c) of this section, an owner or operator who intends to cause or allow sewage, graywater, or other wastewater to be discharged into the marine waters of the state shall submit a plan of sampling techniques and analytical testing methods to be used for purposes of AS 46.03.465 . The plan must include

(1) the quality assurance and quality control measures to be used during sample collection, analysis, and reporting undertaken to comply with AS 46.03.465 ;

(2) a detailed description of sampling techniques, analytical testing methods, and equipment, including information about sampling preservation methods, sample holding times, transportation protocols, and the chain of custody;

(3) laboratory analytical information, including methods used, calibration, detection limits, and the laboratory's quality assurance and quality control measures;

(4) procedures for quality assurance and quality control audits used to determine the effectiveness of the plan; and

(5) procedures for data validation used to assess precision, accuracy, representativeness, comparability, and completeness of the measured parameters in the data obtained from the samples.

(b) Sampling under AS 46.03.465 may not occur before the department approves a plan of sampling techniques and analytical testing methods.

(c) An approved plan of sampling techniques and analytical testing methods is valid for three years. The department will approve the plan if the

(1) department determines that the plan provides sufficient measures for quality assurance and quality control; and

(2) analytical testing methods used are on the department's list of approved Analytical Testing Methods for the Commercial Passenger Vessel Environmental Compliance Program, revised as of June 7, 2002 and adopted by reference, or the department determines a proposed method to be substantially equivalent to an approved method on that list.

(d) An owner or operator may submit, at any time, an amendment to a plan of sampling techniques and analytical testing methods. The department will review any proposed amendment promptly and approve or disapprove the proposed amendment at the earliest practicable time.

(e) Between November 15 and January 15, the department will require changes that the department reasonably determines to be necessary to a valid plan of sampling techniques and analytical testing methods. The changes required under this subsection will be effective 90 days after the date the department provides notice of the required changes.

(f) The owner or operator shall maintain a copy of the valid, approved plan of sampling techniques and analytical testing methods on board each vessel that the owner or operator causes or allows to be operated in the marine waters of the state.
