All existing and newly constructed interceptors shall be operated in accordance with the manufacturer’s specifications. The maintenance frequency for all Commercial Users with interceptors shall be determined by the following:
A. Where installed, an interceptor shall be fully maintained by the User, at its sole expense, in a continuous and efficient manner, and at all times subject to SGRWRF inspection and approval.
B. Interceptors shall be maintained in efficient operating condition by the periodic removal of the full contents of the interceptor. Interceptors shall be fully emptied and cleaned at a frequency such that the combined floating and settled FOGS accumulation does not exceed twenty-five percent (25%) of the design hydraulic depth of the Interceptor This is to ensure that the minimum hydraulic retention time, and required available volume, is maintained to effectively intercept and retain FOGS.
C. If an interceptor at any time is observed by the Pretreatment Coordinator or his or her designee to contain floating and settled FOGS accumulation in excess of twenty-five percent (25%), the User shall be required to have the interceptor serviced as soon as possible, but no later than ten (10) days from the date the notice of violation was given, such that all FOGS, sludge, and other materials, are completely removed from the interceptor.
D. The owner of the property on which a Common Interceptor, and/or the facilities discharging to a Common Interceptor, are located shall be primarily responsible for the maintenance, upkeep, and repair of the interceptor.
E. No Commercial User shall increase the use of water or in any other manner attempt to dilute a discharge as a way of achieving compliance with the Washington City Wastewater/Pretreatment Regulations Ordinance (this chapter). (Ord. 2018-27, 11-14-2018)
