NPDES permit

The National Pollutant Discharge Elimination System (NPDES) is a cornerstone of the federal efforts to control water pollution (21). It determines what can be discharged to a pubHcly owned treatment plant. Indirect discharges may not be required to obtain an NPDES permit but must meet pretreatment effluent limitations and conditions of the NPDES permit of the treatment plant caimot be exceeded. 

Enter the latitudinal and longitudinal coordinates of your facility. Sources of these data include EPA permits (e.g., NPDES permits), county properly records, lacility blueprints, and site plans. Instaictions on how to develop these coordinates can be found in Appendix F. Enter only numerical data. Do not preface numbers with letters such as N or W to denote the hemisphere. 

If the water quality of a water body is potentially affected by a proposed action (e.g., construction of a wastewater treatment plant), a NPDES permit may be required. The Environmental Protection Agency is responsible for this program however, in most cases, has turned this responsibility over to the states as long as the individual state program is acceptable.

The large number of existing oilfield facilities operation in or discharging produced water into surface waters of the United States has prompted EPA to issue general NPDES permits. The general permit allows discharge of low-toxicity drilling fluid directly to the sea.

Effluent containing methyl parathion may not be discharged into lakes, streams, ponds, estuaries, oceans, or public waters unless the compound is specifically identified in a National Pollutant Discharge Elimination System (NPDES) permit. Moreover, discharge of effluent that contains methyl parathion is forbidden without prior notice to the sewage treatment plant authority (NPIRS 1986).

Direct discharges are discharges from point sources into surface water pursuant to a National Pollutant Discharge Elimination System (NPDES) permit. NPDES permits are granted on a case-by-case basis and limit the permissible concentration of toxic constituents or conventional pollutants in effluents discharged to a waterway. These limits are generally established on the basis of the best available treatment technology and, where necessary, to protect surface water quality standards. 

Under indirect discharges, the wastewater is first sent to a publicly owned treatment works (POTW), and then, after treatment by the POTW, discharged pursuant to an NPDES permit. Under these requirements, the generator of the wastes cannot simply transfer the waste materials to a POTW. Rather, the wastes must satisfy applicable treatment and toxic control requirements known as pretreatment standards, where they exist. POTWs that receive hazardous wastes for treatment are also subject to certain RCRA permit-by-rule requirements, and remain subject to RCRA corrective action. 

Discharges to surface waters from an RCRA-permitted facility must comply with the limitations set forth in an NPDES permit. This means that either the facility itself has obtained an NPDES permit or the wastes meet CWA pretreatment standards and have been transported to a POTW.

Wastewater is treated in on-site wastewater treatment facilities and then discharged to publicly owned treatment works (POTWs) or discharged to surface waters under National Pollution Discharge Elimination System (NPDES) permits. Petroleum refineries typically utilize primary and secondary wastewater treatment.
