(A) The federal categorical pretreatment standards found at 40 C.F.R. Chapter I, Subchapter N are hereby incorporated by reference. No user shall introduce or cause to be introduced into the POTW any pollutants, substances or wastewater in violation of any federal categorical pretreatment standard applicable to such user.
(B) Where a categorical pretreatment standard is expressed only in terms of either the mass or the concentration of a pollutant in wastewater, the coordinator may impose equivalent concentration or mass limits in accordance with 40 C.F.R. § 403.6(c).
(C) When wastewater subject to a categorical pretreatment standard is mixed with wastewater not regulated by the same standard, the coordinator shall impose an alternate limit using the combined wastestream formula in 40 C.F.R. § 403.6(e).
(D) A user may obtain a variance from a categorical pretreatment standard if the user can prove, pursuant to the procedural and substantive provisions in 40 C.F.R. § 403.13, that factors relating to its discharge are fundamentally different from the factors considered by EPA when developing the categorical pretreatment standard.
(E) A user may obtain a net gross adjustment to a categorical standard in accordance with 40 C.F.R. § 403.15.
