For construction sites disturbing 1 acre or more of land or part of a common plan of development or sale that disturbs 1 acre or more: The permit requires a Stormwater Pollution Prevention Plan (SWPPP) as well as maintaining records and good housekeeping requirements.

When a project replaces vegetation or other pervious surfaces with one or more acres of cumulative impervious surface, one (1) inch of the runoff from the new impervious surface must be retained on site using volume reduction practices such as infiltration. When volume reduction is prohibited and can’t be achieved onsite, the one (1) inch of volume from the new impervious surfaces created by the project must be treated by other means such as filtration or wet sedimentation basins as required in the permit.  

Trained personnel are required for those preparing the SWPPP, overseeing implementation, and performing or supervising the installation, maintenance and repair of BMPs.

Rules: 7090.2000

Statutes: 115
