F. Temporary pH value excursions that comply with the provisions or this section of the Ordinance will not be considered violations of the user's discharge permit but shall be reported in the pretreatment self-monitoring report with copies of the associated pH recorder charts. 2.6 City's Right of Revision The City reserves the right to establish, by ordinance or in wastewater discharge permits, differing standards or requirements on discharges to the POTW. 2.7 Special Agreement The City reserves the right to enter into special agreements with users setting out special terms under which they may discharge to the POTW. In no case will a special agreement waive compliance with a categorical pretreatment standard or federal pretreatment requirement. However, the user may request a net gross adjustment to a categorical standard in accordance with 40 CFR 403.15. They may also request a variance from the categorical pretreatment standard from the Approval Authority in accordance with 403.13. 2.8 Dilution A user shall not increase the use of process water, or in any way attempt to dilute a discharge, as a partial or complete substitute for adequate treatment to achieve compliance with an applicable pretreatment standard or requirement unless expressly authorized by an applicable pretreatment standard or requirement. The Director may impose mass limitations on users which he believes may be using dilution to meet applicable pretreatment standards or requirements, or in other cases when the imposition of mass limitations is appropriate. 2.9 Pretreatment Facilities A. General: Users shall provide all known, available, and reasonable methods of prevention, control, and treatment (AKART) as required to comply with this ordinance and shall achieve compliance with all applicable pretreatment standards and requirements set out in this ordinance within the time limitations specified by the EPA, the State, or the Director, whichever is more stringent. Any facilities required to pretreat wastewater to a level acceptable to the City shall be provided, operated, and maintained at the user's expense. 19
