Stormwater Plan Preparation

All construction sites disturbing 1-acre or greater must prepare a storm water plan. Stormwater plans go by various names such as: Storm Water Pollution Prevention Plans (SWPPP, or SWP3), Stormwater Management Plans etc.

All operators are required to develop a SWPPP that describes:
- Construction activities;
- The physical attributes of the site;
- The nature of the construction activities;
- Stormwater discharge characteristics;
- Responsible parties for BMP implementation; and
- The selection, design, installation, and maintenance of all stormwater Best Management Practices (BMPs) used to satisfy the effluent limitations of the Construction General Permit (CGP).

It should also be known that the SWPPP MUST be developed PRIOR to submitting the Notice of Intent (NOI) as well.
