Purpose and applicability

1. This chapter establishes responsibilities of state and local government, industry, and the public to implement the national pretreatment standards to control pollutants, which pass through or interfere with treatment processes in publicly owned treatment works or which contaminate sewage sludge. 2. The regulations in this chapter apply: a. To pollutants from nondomestic sources covered by pretreatment regulations, which are indirectly discharged into or transported by truck or rail or otherwise introduced into publicly owned treatment works; b. To publicly owned treatment works which receive wastewater from sources subject to pretreatment regulations; and c. Any new or existing sources subject to pretreatment regulations. Pretreatment regulations do not apply to sources which discharge to a sewer which is not connected to a publicly owned treatment works treatment plant.
