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.
The Stormwater Associated with Commercial Activity General Permit, found only in Connecticut, requires operators of large paved commercial sites such as malls, movie theaters, and supermarkets to undertake actions such as parking lot sweeping and catch basin cleaning to keep stormwater clean before it reaches water bodies.
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.
