Stormwater Pollution Prevention Planning

Stormwater Pollution Prevention Planning (SWPPP and SW3P)

Stormwater Management Plans

The National Pollutant Discharge Elimination System (NPDES) regulations require all facilities that discharge pollutants into US water bodies to have a permit. Before granting a new permit, regulators require your facility to develop a Stormwater Pollution Prevention Plan (SWPPP).

EEC Environmental works with state, federal, and private entities to ensure all permitting requirements of the SWPPP (sometimes called SW3P) are in place.

The SWPPP Requirements

An SWPPP is a written document (authorized by an executive) that identifies all the site factors that could lead to pollutants discharging into the nation’s waters. The document also lists all the preventative measures the facility will take to limit the unwanted discharge of stormwater pollution.

To start the process, your facility submits a notice of intent (NOI) via the SMARTS database to the state (or in some cases, federal) regulators. The NOI lists the pollutants you expect to discharge and names the receiving waters.

Contents of the SWPPP

Once you file the NOI, you’ll need to provide regulators with a site-specific SWPPP. The different control measures you employ will vary depending on the type of facility and pollutants involved.

According to the NPDES requirements, the submitted SWPPP should include:

  • A site description including a site map with all locations related to stormwater and potential sources of pollution identified.
  • The team members (called the Pollution Prevention Team) responsible for developing and updating the SWPPP, including the monitoring and implementation of the control measures.
  • A breakdown of the activities that may cause pollution.
  • The control measures, schedules, and facility procedures that will prevent specific pollutants from discharging into water systems.
  • Spill response plans for any unexpected discharges that do take place.
  • Inspection and monitoring schedules including the frequency, parameters, and procedures.
  • A documented employee-training program regarding the SWPPP procedures, control measures, and best practices.

Updating the SWPPP

If any of the conditions or operations at the site change, the pollution prevention team should update the SWPPP.

The circumstances that could prompt an SWPPP update are:

  • Introducing new chemicals or processes to the site.
  • Removing chemicals, tanks, or changing of the processes at the site.
  • Changing conditions of operations or storage locations from inside to outside or vice-versa.
  • Replacing personnel who play an active role in the SWPPP and its implementation.

Your facility should also review the SWPPP when renewing the permit. The latest, authorized version of the SWPPP should be available on-site for reference and audit purposes, and a Change of Information request with the new SWPPP should be submitted to SMARTS
