§ 20.40.090. Pollution abatement report.

A.

In addition to the foregoing, a subdivision must be planned so it will not:

1.

Contribute to nitrate concentrations in groundwater that exceed existing State standards;

2.

Contribute to fecal coliform bacteria contamination; or

3.

Cause other pollutants to exceed concentrations beyond the acceptable limits set by 18 AAC Chapter 70.

B.

Except as provided in KPB 20.40.090(C) of this section, if an applicant proposes disposal of wastewater to onsite soils for a single-family or duplex residential lot of less than 40,000 square feet, the applicant shall submit a pollution abatement report containing calculations showing that the nitrate concentration of the groundwater aquifer most likely to be affected by the proposed disposal systems will not be increased beyond State drinking water standards at the property line of each lot smaller than 40,000 square feet. The calculations must be sealed by a qualified engineer. To prepare the calculations required under this subsection, there are many groundwater modeling references from which to choose, including those listed in 18 AAC 72.070. For a subdivision with lot sizes of 40,000 square feet or more, these calculations are not required.

C.

The requirements of (B) of this section do not apply to lots in subdivisions that have, or will have, a public water system capable of delivering water to each lot. If a public water system is proposed for a subdivision, but not constructed, construction assurance for the water system is required.
