(a) Primary responsibility for determining whether a proposed development will comply with the standard set forth in Section
14.60.100 may lie with a sewer purveyor other than the City, and the developer must comply with the detailed standards and specifications of such purveyor. The relevant agencies are listed in subsection
(b) of this section. Whenever any such purveyor requires detailed construction or design drawings before giving its official approval to the proposed sewage disposal system, the authority issuing a permit under this chapter may rely upon a preliminary review by such purveyor of the basic design elements of the proposed sewage disposal system to determine compliance with Section
14.60.100. However, construction of such system may not be commenced until the detailed plans and specifications have been reviewed and any appropriate permits issued by such purveyor.
(b) In the following
if-then list, the
if statement describes the type of development and the
then statement indicates the purveyor that must certify to the city whether the proposed sewage disposal system complies with the standard set forth in Section
14.60.100.
(1) If: The use is located on a lot that is served by the city sewer system or a previously approved, privately owned package treatment plant, and the use can be served by a simple connection to the system (as in the case of a single family residence) rather than the construction of an internal collection system (as in the case of a shopping center or apartment complex):
Then: No further certification is necessary.
(2) If: The use (other than a subdivision) is located on a lot that is served by the city sewer system but service to the use necessitates construction of an internal collection system (as in the case of a shopping center or apartment complex); and
a. The internal collection system is to be transferred to and maintained by the city:
Then: The public works director must certify to the city that the proposed internal collection system meets the city's specifications and will be accepted by the city. (A "Permit to Construct" must be obtained from the Washington State Department of Ecology.)
b. The internal collection system is to be privately maintained:
Then: The public works director must certify that the proposed collection system is adequate.
(3) If: The use (other than a subdivision) is not served by the city system but is to be served by a privately operated sewage treatment system (that has not previously been approved) with 3,000 gallons or less design capacity, the effluent from which does not discharge to surface waters:
Then: The Snohomish County Health Department (SCHD) must certify to the city that the proposed system complies with all applicable state and local health regulations. If the proposed use is a single dwelling other than a mobile home, the developer must obtain an improvement permit from the SCHD. If the proposed use is a single-family mobile home, the developer must present to the City a certificate of completion from the SCHD.
(4) If: The use (other than a subdivision) is to be served by a privately operated sewage treatment system (not previously approved) that has a design capacity of more than 3,000 gallons or that discharges effluent into surface waters:
Then: The Washington State Department of Ecology (DOE) must certify to the city that the proposed system complies with all applicable state regulations. (A "Permit to Construct" and a "Permit to Discharge" must be obtained from DOE.)
(5) If: The proposed use is a subdivision; and
a. Lots within the subdivision are to be served by simple connection to existing city lines or lines of a previously approved private system:
Then: No further certification is necessary.
b. Lots within the subdivision are to be served by the city system but the developer will be responsible for installing the necessary additions to the city system:
Then: The public works director must certify to the city that the proposed system meets the city's specifications and will be accepted by the city; and the plans must be reviewed and approved by DOE.
c. Lots within the subdivision are to be served by a sewage treatment system that has not been approved, that has a design capacity of 3,000 gallons or less, and that does not discharge into surface waters:
Then: The Snohomish County Health Department must certify that the proposed system complies with all applicable state and local health regulations. If each lot within the subdivision is to be served by a separate on-site disposal system, the SCHD must certify that each lot shown on a major subdivision preliminary plat can probably be served, and each lot on a major or short subdivision final plat can be served by an on-site disposal system.
d. Lots within the subdivision are to be served by a privately operated sewage treatment system (not previously approved) that has a design capacity in excess of 3,000 gallons or that discharges effluent into surface waters:
Then: The Washington State Department of Ecology (DOE) must certify that the proposed system complies with all applicable state regulations. (A "Permit to Construct" and a "Permit to Discharge" must be obtained from DOE.)
