Rhode Island Pretreatment Regulations (250-RICR-150-10-2)


250-RICR-150-10-2 ACTIVE RULE

2.1 Purpose and Objectives

A. These regulations establish a state and local pretreatment system in conjunction with the National Pretreatment Standards in order to control pollutants which pass through or interfere with treatment processes in Publicly Owned Treatment Works (POTWs) or which may contaminate sewage sludge. These regulations implement R.I. Gen. Laws Chapter 46‑12 in conformance with the Clean Water Act, 33 U.S.C. § 1251, et seq., and those regulations and standards promulgated by the United States Environmental Protection Agency (EPA). It imposes responsibilities on the state, local government, industry and the public to help implement pretreatment standards.

B. These regulations are intended to fulfill three objectives:

1. To prevent the introduction of pollutants into POTWs which will interfere with the operation of a POTW, including interference with its use or disposal of municipal sludge;

2. To prevent the introduction of pollutants into POTWs which will pass through the treatment works or otherwise be incompatible with such works; and,

3. To improve opportunities to recycle and reclaim municipal and industrial wastewaters and sludges.

2.2 Authority

The authority for these regulations is vested in the Director by R.I. Gen. Laws Chapter 46-12, Water Pollution, Chapter 42-17.1, Environmental Management and Chapter 42-17.6, Administrative Penalties for Environmental Violations. These Rules and Regulations are further promulgated pursuant to the requirements and provisions of all Chapters of the R.I. Gen. Laws relating to the duties and responsibilities of the Director for the waters of the State, and in accordance with the requirements of R.I. Gen. Laws Chapter 42-35, Administrative Procedures Act.

2.3 Incorporated Materials

2.5 Application

A. The terms and provisions of these Rules and Regulations shall be liberally construed in conjunction with the Clean Water Act, 33 U.S.C. § 1251, et seq., and accompanying Federal Regulations to allow the Department to effectuate the purposes of state law.

B. Upon adoption by EPA or the State of additional or more stringent regulations affecting the Rhode Island Pollutant Discharge Elimination System Permit Program or the pretreatment standards, these rules shall be revised to comply with such new regulations following the notice, hearing and public comment provisions of the Rhode Island Administrative Procedures Act, R.I. Gen. Laws Chapter 42‑35.

C. These regulations apply to:

1. Pollutants from non‑domestic sources covered by Pretreatment Standards which are indirectly discharged into or transported by truck or rail or otherwise introduced into POTWs as defined in § 2.4(A) of this Part;

2. POTWs which receive wastewater from sources subject to National Pretreatment Standards; and,
