Users shall provide wastewater pretreatment as necessary to comply with this chapter and shall achieve compliance with all categorical pretreatment standards, local limits, and the prohibitions set out in PMC 13.90.050 within the time limitations specified by EPA, the state, or the Public Works Director, whichever is more stringent. Any facilities necessary for compliance shall be provided, operated, and maintained at the user’s expense, and satisfy state requirements for review and approval of plans for wastewater facilities as described in PMC 13.90.070. Such plans (engineering report, plans and specifications, and O&M manuals) shall be submitted as required by Chapter 173-240 WAC to either the Public Works Director or the Department of Ecology for review and users shall obtain approval prior to construction. The review of such plans and operating procedures shall in no way relieve the user from the responsibility of modifying such facilities as necessary to produce a discharge acceptable to the City under the provisions of this chapter. [Ord. 4169 § 1, 2014; Code 1970 § 13.62.030(A).]
