Storm Water Permits and Plans

General: Facilities with a stormwater discharge associated with industrial activity subject must request authorization for and obtain coverage under an NDPES permit. Coverage may be obtained under this general permit, or by meeting the requirements for permit exemption or exclusion. This program does not relieve a facility with other Clean Water Act requirements relating to direct discharges, wetlands and special aquatic restrictions, and community requirements.

Stormwater Associated with Industrial Activity means the discharge from any conveyance that is used for collecting and conveying stormwater and which is directly related to manufacturing, process or raw materials storage areas at an industrial plant.

If your facility has “no exposure” (all industrial materials and activities are protected by storm resistant shelter to prevent exposure to precipitation, snowmelt, surface runoff or drainage) then a certification that there is “no exposure” must be submitted.

There are 11 categories some of the more common are listed below.

Category (i) Facilities subject to stormwater effluent limitation guidelines, new source performance standards, or toxic pollutant effluent standards under 40 CFR Subchapter N (numerous activities and processes). There are already 57 specific industry requirements relating to water run-off of facilities. Category (ii) Certain specific industries Series 24, 26, 28, 29, 311, 32, 33, 34, 373. Category (iii) Mineral Industries, Category (iv) Hazardous Waste Activities, Category (viii) Transportation Activities. Category (xi) Light Industry activities

The EPA program documents includes material handling equipment (including earth moving).

Obtaining Authorization – Notice of Intent
Submission of a Notice of Intent must be submitted, even if already submitted. There is a change of form that requires certain information be provided. In addition, there is a state fee required at the submission.

For new facilities requiring authorization to discharge stormwater runoff, must submit an NOI at least 60 days prior to commencement of the covered industrial activity.

Stormwater Pollution Prevention (SWP2) plans and Best Management Practices (BMP).
The permittee must develop a stormwater pollution prevention (SWP2) plan that is specific to the industrial activity and site characteristics occurring at the permitted location described in the NOI. The permittee must fully implement and periodically review, and update as necessary, the provisions of their SWP2 plan.

The SWP2 Plan is to be retained on site and made available to State EPA, or MS4 upon request.

The plan requirements are outlined in the EPA/State document. This includes general facility information, description of potential pollutant sources, measures and controls, monitoring and recordkeeping requirements, spill and release requirements and reporting.

Implementation Requirements

• Review facility for versus requirements of the procedure.
• Ensure Notice of Intent (NOI) and Annual review (fees) are submitted.
• Develop documentation a Stormwater (P2) Plan for facility.
• Designate person to administer the Stormwater (P2) plan program.
• Provide local training of site personnel.
• Conduct Inspections required by Site specific Stormwater (P2) Plan
• Maintain inventory of equipment and containment to reduce or eliminate stormwater contamination from facility.
• A log to document a description of incidents and items that need follow-up must be maintained. 
• Visually inspect stormwater quality periodically.
