§ 52.47 SPECIFIC POLLUTANT LIMITATIONS.

   (A)   Limitations may be expressed in terms of mass and/or concentration as deemed appropriate by the POTW.

   (B)   No user shall discharge wastewater except in accordance with a permit or authorization.

   (C)   The federal categorical pretreatment standards may establish limits for various parameters. Any user subject to these federal standards will be required to meet the established limits through a permit issued by the POTW. In addition, the POTW may limit the discharge of other specific substances on a case-by-case basis, if the discharge of that substance would interfere with the proper function of the sewer collection system, contaminate sludge, pose a nuisance or health risk to employees or neighbors of the POTW, or violate any receiving stream water quality standard.

   (D)   Higher concentrations of BOD, TSS and oil and grease may be allowed in the industrial user's permit or authorization, but compliance with the provisions of the POTW's sewer surcharge for treatment of high strength wastewater is required.

§ 52.48 EXCESSIVE DISCHARGES AND DILUTION.

   (A)   YCWSD and the POTW shall deny or condition any new or increased contributions of flow or pollutants, or changes in the nature thereof, when YCWSD and the POTW determines that the contributions by an existing or a new discharger will exceed established standards for that discharger or that contributions will cause a violation of the POTW's NPDES permit which is in effect at the time of the determination or violate a permit or authorization issued by YCWSD or the POTW.

   (B)   No user shall ever increase the use of the process water or in any way attempt to dilute a discharge as a partial or complete substitute for adequate treatment to achieve compliance with the limitations contained in the federal categorical pretreatment standards or in any other pollutant-specific limitation developed by the county, state, or POTW.

§ 52.49 ACCIDENTAL DISCHARGE.

   (A)   Each user shall provide protection from accidental discharge of prohibited materials or other substances regulated by this subchapter. Facilities to prevent accidental discharge of prohibited materials shall be provided and maintained by the owner or user's own cost and expense. Detailed plans showing facilities and operating procedures to provide this protection shall be submitted to YCWSD and the POTW for review, and shall be approved by the YCWSD and the POTW before construction of the facility. All existing users shall complete a plan upon notification by YCWSD and the POTW. No new user who commences contribution to the POTW shall be permitted to introduce pollutants into the system until accidental discharge procedures have been approved by YCWSD and the POTW. Review and approval of the plans and operating procedures shall not relieve the industrial user from the responsibility to modify the user's facility as necessary to meet the requirements of this subchapter. In the case of an accidental discharge, it is the responsibility of the user to notify YCWSD and the POTW immediately by telephone. The notification shall include the location of discharge, type of waste, concentration and volume and corrective action.

   (B)   Within five days following an accidental discharge, the user shall submit to YCWSD and the POTW a detailed written report describing the cause of the discharge and the measures to be taken by the user to prevent similar future occurrences. The notification shall not relieve the user of any expense, loss, damage or other liability which may be incurred as a result of damage to the POTW, fish kills or any other damage to person or property; nor shall the notification relieve the user of any fines, penalties or other liability which may be imposed by this subchapter or other applicable law.

   (C)   (1)   A notice shall be permanently posted by the user on the user's bulletin board or other prominent place advising employees whom to call in the event of a dangerous discharge.

      (2)   Users shall ensure that all employees, if any, who may cause or suffer a dangerous discharge to occur are advised of the emergency notification procedure.
