A SWPPP, or SW3P, is a Storm Water Pollution Prevention Plan.

A SWPPP is a fundamental requirement of stormwater permits in Texas. As runoff flows over land and impervious surfaces, it accumulates debris, chemicals, sediment, etc., that could adversely affect water quality if the runoff discharge is untreated. This will lead to unsafe water for drinking, fishing, swimming and other activities.

A well prepared SWPPP will help a construction operator as follows:

• Identifies all potential sources of pollution which may reasonably be expected to affect the quality of storm water discharges from the construction site.
• Describes practices to be used to reduce pollutants in storm water discharges from the construction site. (We want to divert the clean water, and trap the dirty water)
• Helps assure compliance with the terms and conditions of the permit (when the plan is designed for the individual site, and is fully implemented)
• Provides inspection and reporting procedures.

When do I need a SWPPP in Texas?

Nearly all construction site operators engaged in clearing, grading, excavation activities that disturb one acre or more, including smaller sites in a larger common plan of development or sale, are required to prepare a SWPPP and obtain coverage under National Pollutant Discharge Elimination System (NPDES).

If you’re in Texas, visit the TCEQ website for information on Storm Water Permitting requirements.
