15.60.070 Industrial user pretreatment.
A. When deemed necessary by the city, the user shall, at his own expense, provide treatment or take such other measures required in order to reduce any nuisance, characteristics, content, or rate of discharge of wastes being discharged to the sanitary sewer system so that there is no damage to the sewer system or any undue interference with its operation.
B. Detailed plans showing the pretreatment facilities and an operation and maintenance manual shall be submitted to the city for review and shall be acceptable to the city before construction of the facility. The review of such plans and operating procedures will in no way relieve the user from the responsibility of modifying the facility as necessary to produce an effluent acceptable to the city under the provisions of Chapters 15.44 through 15.76. Any subsequent changes in the pretreatment facilities or method of operation shall be reported to and be acceptable to the city prior to the user’s initiation of the changes.
C. Bypass of Treatment Facilities.
1. Bypass of an industrial user pretreatment process is prohibited unless it is unavoidable to prevent loss of life, personal injury, or severe property damage or no feasible alternatives exist.
2. The permittee may allow bypass to occur which does not cause its effluent limitations to be exceeded, but only if it is also for essential maintenance to assure efficient operation.
3. Notification of Bypass.
a. Anticipated Bypass. If the permittee knows in advance of the need for a bypass, it shall submit prior written notice, at least ten days before the date of the bypass, to the city.
b. Unanticipated Bypass. The permittee shall immediately notify the city and submit a written notice to the POTW within five days. This report shall specify:
(1) A description of the bypass, and its cause, including its duration.
(2) Whether the bypass has been corrected.
(3) The steps being taken or to be taken to reduce, eliminate and prevent a recurrence of the bypass.
D. All records relating to compliance with the requirements of Chapters 15.44 through 15.76 or other pretreatment regulation shall be made available to the city for inspection and copying.
