A stormwater pollution prevention plan or SWPPP a compilation of documents that make out all possible roots of stormwater pollution and also explain procedures to control them. These might include BMP’s or Best Management Practices which eliminate the identified noxious waste and also provide implementation methods in compliance with the conditions in your permit. An SWPPP is available for various locations. However, the most common are at construction sites and industries.
In the case of construction sites, SWPPP is divided into two types the first one is called Comprehensive SWPPP or C-SWPPP and the other one is called On-Site SWPPP or (OS-SWPPP).
The C-SWPPP is a compilation of documents that are submitted under Construction General Permit for coverage consent. It consists of the application, construction site plans and SWPPP document.
Here is a list of all the things that should be addressed in an SWPPP document
- Project Narrative;
- Stormwater Management and Sediment Control Plan
- Sequence of Construction
- Site Features and Sensitive Areas
- Buffer Zone Management
- Sources of Pollution
- Best Management Practices (BMPs)
- Site Maps (such as Vicinity, Topographic, Soils, etc.)
- Engineering Reports
- Non-Numeric Effluent Limits
- Management of Non-Stormwater Discharges
The OS-SWPPP is a compressed form of the C-SWPPP. It contains a variety of information regarding the activities, inspection, maintenance, etc. The OS-SWPPP is formed after the approval of C-SWPPP. The OS-SWPPP should contain
- A Copy or Link to the 2012 Stormwater Construction General Permit
- The Approve Notice of Intent
- The CGP Coverage Approval Letter
- Any necessary Local Approvals to conduct the proposed construction activities
- Any necessary USACOE approvals
- Critical Area Permit authorization
- Logs/Records to Track Site Progress and Rainfall
- CZC Certifications (Coastal Counties Only)
