18 AAC 72.205. Submittal requirements

(a) To obtain approval of plans for collection, treatment, and disposal of domestic wastewater required by 18 AAC 72.200, the applicant must submit to the department

(1) the plan review fee required by 18 AAC 72.955;

(2) a completed system plan review data sheet, on a form supplied by the department or a document that contains the same information, including

(A) the project name and description;

(B) the general location of the project;

(C) the project owner's name, address, and telephone number;

(D) the name, address, and telephone number of a person to contact regarding matters relating to project approval; and

(E) a description of the type of wastewater project proposed;

(3) a completed owner's statement,

(A) on a form supplied by the department or a document that contains the same information; and

(B) signed in accordance with 18 AAC 15.030;

(4) plans consisting of reports or drawings that

(A) clearly and legibly depict the design;

(B) demonstrate compliance with the applicable approval criteria in 18 AAC 72.220 - 18 AAC 72.275; and

(C) demonstrate that

(i) the system meets the minimum design criteria of this chapter;

(ii) a discharge, if any, from the system meets the standards of quality for surface water and groundwater set out in 18 AAC 70; and

(iii) the system protects drinking water sources and systems;

(5) a statement identifying each permit that the department requires for the project; if a required permit has not been secured, but an application for that permit has been submitted for department review, the department will, upon request of the applicant, review the domestic wastewater system plans; the department will condition an approval to construct under 18 AAC 72.225 upon the project receiving all required department permits, with permit disposal limits equal to or less stringent than the assumed values used in preparing and reviewing the wastewater system design;

(6) unless a domestic wastewater system serves only one single-family home, one duplex, or one commercial building, documentation showing the existence, or formation before beginning construction of the system, of a local government organization, a homeowner's association, a private utility, a commercial entity, or other entity, the purpose of which is to operate and maintain the system; if a public utility within the meaning of AS 42.05.990 operates the system, documentation under this paragraph must include a certificate of public convenience and necessity issued by the Alaska Public Utilities Commission under AS 42.05.221 ;

(7) for a domestic wastewater system that has 100 or more service connections or that is used, or intended for use, by 500 or more individuals per day, documentation showing that the operator is or will be certified as required by 18 AAC 74 before operation of the system;

(8) a description of measures to protect nearby surface water from siltation or other contamination resulting from construction of the project;

(9) a description of the provisions to maintain operation of necessary existing flow or treatment processes affected by the project during construction; and

(10) if a wastewater discharge is proposed to an existing collection or disposal system, documentation showing that

(A) the receiving system has sufficient capacity to accommodate flows expected from the proposed discharge; and

(B) the owner of the receiving system has approved the discharge.

(b) Plans submitted in accordance with (a)(4) of this section must be prepared and sealed by a registered engineer for

(1) a system that otherwise would be a conventional onsite system except that the system does not meet the requirements of 18 AAC 72.035(d) (5) for soil type;

(2) a conventional onsite system that

(A) has an average daily design flow of less than 2,500 gpd; and

(B) is installed in an area where

(i) similar systems have been known to fail;

(ii) there is a high groundwater table or poor soil conditions; or

(iii) the department finds the discharge will threaten public health, public and private water systems, or the environment;

(3) a conventional onsite system with a daily design flow of 2,500 gallons or more per day;

(4) alternate onsite systems and alternate soil absorption systems including community sewer systems, package treatment plants, stabilization ponds, and collection and pumping systems;

(5) holding tanks; and

(6) other disposal systems, including marine outfalls and land surface disposal systems under 18 AAC 72.275.

(c) A person proposing a percolating or a nonpercolating stabilization pond must submit, in addition to the information required under (a) of this section, soil boring or other information that is sealed by a registered engineer and that is sufficient to evaluate the items set out in 18 AAC 72.255(a) (6) and (7) and in 18 AAC 72.265(2) , (3), (4), (5), and (10).

(d) A person proposing a percolating stabilization pond must submit, in addition to the information required under (a) of this section, (c) of this section, and 18 AAC 72.255, hydrologic data and mixing calculations, sealed by a registered engineer, that demonstrate compliance with the conditions of any permit issued under this chapter.

(e) A person proposing a community soil absorption system must submit, in addition to the information required under 18 AAC 72.260 and (a) of this section,

(1) a site plan that delineates the usable domestic wastewater disposal area described in 18 AAC 72.260(a) (4) and (7);

(2) calculations in accordance with 18 AAC 72.260(a) (5); and

(3) a soils report that complies with 18 AAC 72.265.

(f) A person proposing to discharge domestic wastewater onto the surface of the land must provide documentation that

(1) the person owns the land treatment area or has written authorization from the landowner to discharge domestic wastewater onto the land;

(2) the land treatment area is protected against public access;

(3) the topography, hydrology, geology, and soil characteristics of the land treatment area are adequate to protect existing and potential water and land uses outside the land treatment area, including subsistence, housing, education, industry, recreation, and agriculture; and

(4) the method of discharge prevents disease transmission.

(g) A person proposing the use of a holding tank for wastewater disposal must submit, in addition to the information required under 18 AAC 72.025,

(1) soil and water table information that is sealed by a registered engineer as required under 18 AAC 72.205(b) , and that demonstrates that a conventional or alternate onsite system is not practical because permafrost or other soil conditions preclude the use of a soil absorption system or other subsurface domestic wastewater disposal system; and

(2) a design with provisions for resisting buoyancy forces when the tank is pumped; the design's provisions must be sealed by a registered engineer as required under 18 AAC 72.205(b) .

(h) Upon request, the department will provide a checklist to assist an applicant in making a complete submittal under this section. The department will return an incomplete submittal to the applicant.
