(1) National categorical pretreatment standards as adopted and hereafter amended by the EPA pursuant to the Act shall be met by all users in the regulated industrial categories. These standards, found in 40 CFR Chapter I, Subchapter N, Parts 405-471, are hereby incorporated by reference.

(2) State requirements and limitations on discharges to the publicly owned treatment works, as incorporated into Washington State law by Chapter 90.48 RCW, shall be met by all users which are subject to such standards in any instance in which they are more stringent than federal requirements and limitations, or those in this chapter or other applicable ordinances.

(3) Any user determined by the city of Stanwood to qualify as a significant industrial user shall file an application for a state waste discharge permit with the department in accordance with the requirements of WAC 173-216-070. Proof of acceptance of the application and payment of permit fees shall be kept at the user’s facilities and produced upon request. Failure to submit the application or rejection of the application by the department may be considered sufficient grounds to terminate or refuse to provide sewer service.

(4) The city reserves the right to establish more stringent standards or requirements on discharges to the sewer system and to set local limits for any pollutant to protect against pass through and interference.
