CT Stormwater Quality Manual - Errata Sheet
Errata Sheet for 2004 Connecticut Stormwater Quality Manual
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 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.
Video Tutorial -- General Permit with modifications
The following tutorial is an overview of the requirements of the General Permit for the Discharge of Stormwater Associated with Industrial Activity, effective October 1, 2011. The video presents general information on permit conditions, control measures, inspections, monitoring, benchmarks, impaired waters requirements, and a discussion of specific requirements for Sector G--Transportation and Public Works Facilities.
These guidelines have been developed to clarify DEEP recommendations to state and municipal officials, and others regarding the removal and disposal of snow accumulations from roadways and parking lots. For purposes of this guidance snow accumulations refers to snow banks and snowpiles that are removed by front-end loader or by loading on trucks for disposal.
This page provides specific instructions to former registrants under the Vehicle Maintenance Wastewater general permit on how to complete the Discharge Notification Form to POTW Authority for the General Permit for Discharges from Miscellaneous Industrial Users (MIU GP).
Connecticut is looking to the future of waste management. CT DEEP and municipalities from across the state are joining together to form the Connecticut Coalition for Sustainable Materials Management (CCSMM) and explore ways to reduce the amount of waste that is generated in our state, improve recycling and organics collection, and other innovative solutions.
