Complying with the Connecticut Stormwater General Permit

Most marinas and boatyards are required to have a permit for the discharge of stormwater from their facilities. This requirement applies to marinas and boatyards that: 1) are classified under Standard Industrial Code (SIC) 4493 (Marinas) and SIC 373 (Ship and Boat Building and Repairing), where portions of the facility are involved in boat, vehicle or equipment maintenance, fueling and/or vehicle or equipment cleaning operations and, 2) have a point source stormwater discharge associated with the industrial activity.

A Point Source discharge is:

The discharge from any conveyance, such as a pipe, ditch, channel, swale, or other discrete discharge (including boat launch ramps and marine railways) which is used for collecting and conveying stormwater that comes from areas related to manufacturing, processing, maintenance, waste disposal, or material and boat storage areas at your site. Typical marina activities considered "industrial activities" include boat maintenance (particularly bottom pressure washing and sanding), painting, engine maintenance and disposal of paints, solvents, engine fluids and other waste materials.


If your facility meets both of these criteria you must:

1) Register your facility for inclusion in the current General Permit for the Discharge of Stormwater Associated with Industrial Activity [WORD .doc] by completing the General Permit Registration Form [WORD .doc] for the Discharge of Stormwater Associated with Industrial Activity and submit a five hundred dollar ($500.00) permit fee to the Department of Environmental Protection.

(If you have previously registered for inclusion in and earlier General Permit for the Discharge of Stormwater Associated with Industrial Activity but have not registered for the current permit issued October 1, 2002, modified July 15, 2003 you only need to complete the Renewal Registration Form [WORD .doc] for the General Permit for the Discharge of Stormwater Associated with Industrial Activity and submit a five hundred dollar ($500.00) permit fee to the Department of Environmental Protection.)


2) Prepare a Stormwater Pollution Prevention Plan (SWPPP) for your facility which provides the information required in the the General Permit for the Discharge of Stormwater Associated with Industrial Activity [WORD .doc]. The SWPPP is a plan that specifically describes your facility, potential pollutant sources, good housekeeping and other best management practices to prevent pollutants from entering stormwater runoff from your facility.

A Sample Stormwater Pollution Prevention Plan (SWPPP) and Templates [WORD .doc] are available. You can prepare the plan "in house" or hire a consultant to prepare the plan. Once it is complete it must be signed by a licensed Professional Engineer (P.E.) or a Certified Hazardous Materials Manager (CHMM).


3) Conduct annual stormwater sampling and submit the results to the Department of Environmental Protection on the Stormwater Monitoring Report Form [WORD .doc].
