Storm Water Permit Resources

With the exception of Major Municipal Storm Sewer Systems (MS4s), discharges of storm water associated with construction activities, industrial activites and small MS4s are covered under general permits.  Storm water general permits are primarily self-implementing, meaning the permittee must develop and implement a site-specific Storm Water Pollution Prevention Plan (SWPPP) and conduct self-inspections.  The following templates,guidance documents and presentations are available to assist permittees with compliance. Please note that permit applicants are not required to use any specific SWPPP template.   Permit applicants may use any of the following templates or design their own SWPPP as long as the contents are in compliance with the applicable general permit.
