Water Regulating and Discharges

• Agricultural Wastewater

  Agricultural wastewater generated from a variety of farm activities including animal feeding operations and the processing of agricultural products, can pollute surface and ground water if not properly managed.

• Flow Proportioned Sample Collection Procedures

  The Regulations require flow proportioning for all daily composite samples. See RCSA Section 22a-430-3(a)(3) for more information. This requirement is often a major area of non-compliance for permittees.

• Common Violations and How To Avoid Them

  Common industrial wastewater violations and how to avoid them.

• Stormwater Manual

  The Connecticut Stormwater Quality Manual provides guidance on the measures necessary to protect the waters of the State of Connecticut from the adverse impacts of post-construction stormwater runoff.

• Industrial Waste Water Contact Information

• What To Expect From An Inspection

  The Department of Energy and Environmental Protection (DEEP) conducts inspections at permitted facilities throughout the state. Under state law inspectors have the authority to enter your facility at reasonable times to evaluate compliance with your permit and the Water Discharge Permit Regulations of the State of Connecticut.

• General Pretreatment Permit for Non-Significant Industrial User Discharges to Publicly Owned Treatment Works (Non-SIU GP)

• General Pretreatment Permit for Significant Industrial User, Dewatering, and Remediation Discharges (SIU GP)

• Construction Stormwater General Permit

  The General Permit for the Discharge of Stormwater and Dewatering Wastewaters from Construction Activities ("Construction Stormwater General Permit") requires developers and builders to implement a Stormwater Pollution Control Plan to prevent the movement of sediments off construction sites into nearby water bodies and to address the impacts of stormwater discharges from a project after construction is complete.

• Industrial Wastewater Discharge Permit Compliance Information

  How to maintain compliance with your individual discharge permit; a summary of key information and requirements that apply to your permit.

• Sample Collection and Documentation

  If you are required to submit DMRs to comply with an Individual NPDES or Pretreatment permit, you are eligible to file electronically.

• NetDMR in Connecticut

  NetDMR is a freely available Web-based tool that allows permittees to electronically sign and submit their discharge monitoring reports (DMRs) or stormwater monitoring reports (SMRs) to EPA via a secure internet connection. NetDMR is designed to improve data quality, save paper, and provide cost savings for permittees and regulators.

• Municipal Stormwater

  The General Permit for the Discharge of Stormwater from Small Municipal Separate Storm Sewer Systems (MS4 General Permit) is the product of a mandate by the U.S. Environmental Protection Agency (USEPA) as part of its Stormwater Phase II rules in 1999. This general permit requires each municipality to take steps to keep the stormwater entering its storm sewer systems clean before that stormwater enters water bodies.

• Stormwater Management

  Stormwater is water resulting from rain or snowmelt that runs off surfaces such as rooftops, paved streets, highways and parking lots. Stormwater results in significant pollution to surface water affecting primary contact recreation such as swimming and aquatic life use support. DEEP is working to engage stakeholders to prevent the introduction of pollutants into stormwater through its Non Point Source Pollution Management and Coastal Nonpoint Source Pollution Control Programs.
