The categorical pretreatment standards found at 40 C.F.R. Chapter I, Subchapter N, parts 405 through 471 are hereby incorporated.
(A) Where a categorical pretreatment standard is expressed only in terms of either the mass or the concentration of a pollutant in wastewater, the Wastewater Superintendent may impose equivalent concentration or mass limits in accordance with 40 C.F.R. § 403.6(c).
(B) When wastewater subject to a categorical pretreatment standard is mixed with wastewater not regulated by the same standard, the Wastewater Superintendent shall impose an alternate limit using the combined waste stream formula in 40 C.F.R. § 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 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.
(D) A user may obtain a net gross adjustment to a categorical standard in accordance with 40 C.F.R. § 403.15.
