Stormwater Pollution Prevention Plan (SWPPP)

Harford Community College

“Construction Stormwater Pollution Prevention Plan

Template The Maryland Department of the Environment (MDE) requires construction operators to develop a Stormwater Pollution Prevention Plan (SWPPP) prior to submitting a Notice of Intent (NOI) for

Construction General Permit (20-CP) coverage (Refer to Part III.F of the permit). To assist with developing a SWPPP that meets the minimum requirements of the General Permit for Stormwater

Associated with Construction Activity, the Maryland Department of the Environment has provided this template.

This template is customizable to your specific project and site.

Once MDE has approved coverage for your project under the 20-CP, include your NOI, your authorization, and a copy of the 20-CP as attachments to the SWPPP.

For more information on the Tier II Checklist, the NOI in ePermits or Cationic Chemical

Treatment, please navigate to our website located here:

https://mde.maryland.gov/programs/water/wwp/Pages/gp_construction.aspx

Instructions for Using the SWPPP Template

Each section of the SWPPP Template includes instructions and space for your project and site information. Read the instructions for each section before you complete that section. The blue text indicates what information is to be included.

The SWPPP Template is an editable document file. You may add tables or additional text and/or delete unneeded or inapplicable fields. The information provided in each section may vary in length.

The following items may help you better prepare for completing the SWPPP:

● Make sure you read the General Permit thoroughly before you begin preparation of your

SWPPP. By doing so, you are ensuring that you have a working understanding of the permit’s underlying requirements.

● Remember to complete the SWPPP prior to submitting your Notice of Intent (NOI) for permit coverage when required.

● If there is more than one construction operator or individual/entity that will be responsible for separate phases or parts of the construction for your project, consider coordinating the development of your SWPPP with the other operators or individuals/entities.

While MDE has made every effort to ensure the accuracy of all instructions contained in the

SWPPP Template, it is ultimately the permit that determines the obligations of regulated construction stormwater discharges. In the event of a conflict between the SWPPP Template and any corresponding provision of the 20-CP, you must abide by the requirements in the permit. MDE welcomes feedback on the SWPPP Template. Future revisions of this document will consider all feedback.
