(A) National categorical pretreatment standards. National categorical pretreatment standards, as promulgated by the U.S. Environmental Protection Agency (EPA) pursuant to the Act (33 U.S.C. 1345 et seq.) and as adopted as Appendix C to this article, which appendix is on file in the office of the City Clerk, shall be met by all dischargers of the regulated industrial categories. An application for modification of the national categorical pretreatment standards may be considered for submittal to the regional administrator by the approval authority, when the approval authority’s wastewater treatment system achieves consistent removal of the pollutants as defined by 40 C.F.R. 403.7.
(B) State requirements. State requirements and limitations on discharges to the POTW shall be met by all dischargers which are subject to such standards in any instance in which they are more stringent than federal requirements and limitations or those in this or any other applicable ordinance.
(C) Right of revision. The approval authority reserves the right to amend this article to provide for more stringent limitations or requirements on discharges to the POTW where deemed necessary to comply with the objectives set forth in § 68-186.
(D) Dilution. No discharger shall increase the use of potable or process water in any way nor mix separate waste streams for the purpose of diluting a discharge as a partial or complete substitute for adequate treatment to achieve compliance with the standards set forth in this article.
(E) Notice of potential problems. All categorical and noncategorical industrial users shall notify the POTW immediately of all discharges that could cause problems to the POTW, including any slug loadings, as defined by 40 C.F.R. 403.5(b), by the industrial user.
(F) Net/gross and federal categorical pretreatment standards. A user may apply to the city for an adjustment in a federal categorical pretreatment standard to reflect the presence of pollutants in the user’s intake water in accordance with 40 C.F.R. 403.15. If such an adjustment is made, the adjusted federal categorical pretreatment standard shall apply, provided the adjustment will not result in interference or pass through.
(G) Removal credits. Removal credits will be awarded to those POTWs who follow the requirements set in 40 C.F.R. 403.7.
(H) RCRA notification. It is the responsibility of the industrial user to notify the POTW, the EPA Regional Waste Management Director, and the state hazardous waste authorities, in writing, of any discharge into the POTW of a substance which, if otherwise disposed of, would be a hazardous waste under 40 C.F.R. 261.
