The federal general pretreatment regulations for existing and new sources of pollution found at 40 CFR Chapter 1, Subchapter Parts 405-471 are hereby incorporated by reference as follows:
(A) Where a categorical pretreatment standard is expressed only in terms of either the mass or the concentration of a pollutant in wastewater, the control authority may impose equivalent concentration or mass limits in accordance with 40 CFR § 403.6(c).
(B) When wastewater subject to a categorical pretreatment standard is mixed with wastewater not regulated by the same standard, the control authority must impose an alternate limit using the combined waste stream formula in 40 CFR § 403.6(e).
(C) 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 CFR 403.13, that factors relating to its discharge are fundamentally different from the factors considered by EPA when developing the categorical pretreatment standard.
(D) A user may obtain a net gross adjustment to a categorical standard in accordance with 40 CFR § 403.15.
