24.17.110 Building permit review and land use determination.
(1) In order to obtain a building permit for any property that is currently served by an OSS, the local building official shall request that CCPH determine if the current OSS is adequate for the proposed use and is operating properly only when the building activity may interfere with any component or increase the effluent flow to the OSS. CCPH shall require:
(a) A desk review when sufficient records exist to evaluate potential impacts to the operation of the OSS and its reserve area; or
(b) A desk review and field inspection if the OSS is not permitted or if there are insufficient records to make a determination;
(c) A full locate of all OSS components may be required if CCPH deems this necessary to make a determination;
(d) A current O&M inspection per Section 24.17.170.
(e) If CCPH determines that there are no apparent barriers to the proposed building project in terms of the impact on the OSS or reserve area, they will issue a CCPH release to the building official so stating. CCPH release decisions shall be valid for one (1) year following date of issuance. If CCPH determines that the proposed building project would adversely impact the OSS or reserve area, a CCPH release will not be issued.
(2) Proposed Land Use Determinations. Alteration of existing lot lines, short plats, subdivisions where determination of adequacy required by local planning or building officials requires CCPH evaluation of the existing OSS and reserve area for the proposed lot configuration. Every short subdivision as defined in this chapter shall comply with the provisions of any local regulation adopted pursuant to RCW 58.17.060.
(a) CCPH shall determine adequacy and legal conformance by conducting a verification of the existing OSS. If the OSS is deemed inadequate or illegal nonconforming, a replacement OSS or other actions to bring the OSS into conformance with this chapter shall be required.
