Can the Stormwater Pollution Prevention Plan (SWPPP) exceed Part IV requirements of the CGP?

The Stormwater Pollution Prevention Plan (SWPPP) can indeed exceed the Part IV requirements of the Construction General Permit (CGP). This is based on the understanding that while the CGP provides a baseline for stormwater management and pollution prevention, the specific conditions of a project site may necessitate more stringent measures to effectively manage stormwater runoff and minimize pollution.

A more comprehensive SWPPP may be developed to address unique site conditions, such as the presence of sensitive ecosystems, higher potential for erosion, or existing environmental regulations that go beyond the minimum standards of the CGP. By exceeding these requirements, a SWPPP can provide enhanced protection for water quality and help meet local, state, or federal environmental standards, which may be stricter than those outlined in the CGP.

This flexibility allows project managers to implement best management practices that are tailored to the site-specific needs and risks, ultimately benefiting both the environment and the regulatory compliance process.
