*Note: If the permitted activity is in an MS4 municipality, the municipality must ensure the approval of the Post Construction Stormwater Management (PCSM) plan. The applicant should send the PCSM plan to the MS4 municipality along with the municipal notification. Even where the approval of the PCSM plan is not required, the permittee must develop and implement the PCSM and certify that the BMPs were implemented in accordance with the PCSM plan when the Notice of Termination (NOT) is submitted.
**Although the E&S plan approval is not required under the Chapter 102 Regulations for these activities, E&S approval may be required by the municipal ordinance, or another DEP permit (i.e. - Chapter 105 Joint Permit, or GPs).

What is a Post-Construction Stormwater Management Plan (PCSM Plan)?
A site specific plan identifying Best
Management Practices (BMPs) to manage stormwater runoff after construction
activities have ended and the project site has been permanently stabilized to
protect and maintain existing and designated uses. The PCSM plan should be
designed to maximize volume reduction technologies, eliminate or minimize point
source discharge to surface waters, preserve the integrity of stream channels,
and protect the physical, biological and chemical qualities of the receiving
surface water. The PCSM Plan must contain a
written narrative, including calculations or measurements, and justifications
for each BMP.
