14.36.170 Wellhead protection area standards of mitigation.
A. Every application for a non-exempt development permit for a new use or expansion of an existing use within a wellhead protection area shall meet these minimum standards for mitigation:
1. If the proposal indicates the use, storage, handling or disposal of hazardous materials above the minimum quantity thresholds listed in LMC 14.36.160, the applicant shall submit a hazardous materials management (spill) plan as outlined in LMC 14.36.160.
2. Any existing wells on the site that are not actively used for domestic water use, irrigation or monitoring, or are not maintained and in such disrepair as to be unusable, will be decommissioned by the applicant following the procedures in WAC 173-160-381.
3. The city may require dedicated groundwater monitoring wells to be installed for the project in situations where groundwater contamination risks or monitoring needs are identified. The wells will be installed and equipped by the applicant to city standards.
4. The proposal must ensure compliance with the city of Lacey stormwater maintenance requirements, as described in Section 5.100 of the City of Lacey Development Guidelines and Public Works Standards, and in LMC 14.27.060.
5. The city may allow alternatives to the minimum mitigation standards described in this section in unique conditions and on a case-by-case basis when the applicant demonstrates that:
a. The project has been evaluated by a hydrogeological report as described in LMC 14.36.140; and
b. Based upon the hydrogeological report and the best available science the proposed alternative mitigation measures will be adequate to protect the drinking water source. (Ord. 1638 §15, 2023; Ord. 1505 §44 (part), 2017).
