§ 20.40.060. Onsite treatment systems with individual marine outfalls.

A.

If any lots within a subdivision will employ an onsite treatment system plan with an individual marine outfall, the following requirements must be met:

1.

The preliminary subdivision plat must clearly show access from the lot to marine waters for wastewater disposal for each lot with a proposed marine outfall, by direct access, easement, or other authorization (this may require a detail drawing);

2.

A soils analysis and report, sealed by a qualified engineer, with sufficient soils data to demonstrate that neither a conventional nor an alternate onsite soil absorption system is practicable for the lot in question;

3.

Plans for the treatment and disposal system proposed for each lot, or single typical design for each group of identical systems, as required under 18 AAC 72.200 - 18 AAC 72.205, the plans must be sealed by a qualified engineer;

4.

Construction and necessary operation of the treatment system by the lot owners is feasible;

5.

Dispersion and mixing calculations must show that each outfall and the cumulative impact from all of the outfalls complies with this chapter and 18 AAC Chapter 70, Water Quality Standards, or otherwise complies with permit conditions; and

6.

A minimum lot size necessary to maintain the applicable separation distances set out in 18 AAC 72.020 from any part of the wastewater systems.

B.

For a wastewater treatment and disposal system proposed under this section, the requirements of 18 AAC 72. 205 and 18 AAC 72.275 for prior Alaska Department of Environmental Conservation approval of wastewater discharge permits will apply only to persons who propose actual discharges, and will not apply to conceptual plan of wastewater treatment and disposal for a subdivision covered under this section.

C.

Before a final plat is filed for subdivision, the qualified engineer must complete the following plat note which shall be placed on the plat:

WASTEWATER DISPOSAL: Plans for wastewater treatment systems with individual marine outfalls serving single family or duplex residences, that meet the regulatory requirements of KPB 20.40.060, are on file at the Kenai Peninsula Borough. Any type of wastewater treatment and disposal system disposing of wastewater onsite or through an outfall must meet the regulatory requirements of the Alaska Department of Environmental Conservation.
