SWPPP - Does My Stormwater Pollution Prevention Plan Expire?

From time-to-time, Caltha receives inquiries from facilities that believe their Stormwater Pollution Prevention Plan (SWPPP) may have "expired".

The SWPPP, prepared in accordance with State or EPA permit requirements, is a "dynamic" document, and does not expire. However, at any point in time, the SWPPP needs to accurately reflect the current physical layout of the facility, the existing stormwater controls and spill containment and control measures, and the current emergency response procedures.

Because facilities change overtime, the SWPPP needs to be reviewed and updated accordingly. In many cases, the SWPPP needs to be amended prior to making the changes. The SWPPP may have to be revised for a number of different reasons, including:

  • Changes to physical layout of the site

  • Changes to locations for specific industrial activities

  • Changes to materials handled at the site

  • Changes to best management practices (BMPs) or stormwater controls

  • Changes to Pollution Prevention Plan team members and/or responsibilities.

Facilities may also need to review and revise the SWPPP in response to issues that are identified during site inspections, site compliance evaluations, or benchmark stormwater monitoring results.
