Effective June 30, 2015 New or Updated Erosion Control Plans Required
Some active construction projects must comply with expanded erosion and sediment control requirements to protect local creeks, bays and the ocean.
For projects that will include soil disturbance during construction, applicants must submit an Erosion and Sediment Control Plan (ESCP) for approval by the municipality prior to the issuance of certain permits, including all Grading Permit, most Building Permits, other permits at the discretion of the municipality (e.g. Encroachment or Demolition Permits with potential for significant erosion or non-stormwater discharges), and projects designated by local authorized official or designated municipal staff.
The purpose of the ESCP is to:
- Identify potential pollutant sources that may affect the quality of stormwater runoff discharges from the construction site.
- Document the Best Management Practices (BMPs) that will be implemented and placed in order to prevent, to the maximum extent practicable, construction site pollutants from leaving the site and entering the storm drain system during all phases of construction.
- Document erosion control, sediment control, and good housekeeping BMPs that must be implemented year round as appropriate based on construction activities.
The ESCP may require modification as the project progresses and as conditions warrant. All modifications to the approved ESCP must be submitted to the municipality for review and approval. Open the MCSTOPPP Erosion and Sediment Control Plan Applicant Package to get started.
If a project disturbs one acre or more of soil, it is subject to the State Construction General Permit (CGP). In this circumstance, the Stormwater Pollution Prevention Plan (SWPPP) developed pursuant to the CGP may substitute for the ESCP.
What should be in the Erosion and Sediment Control Plan
The Erosion and Sediment Control Plan ESCP applicant package provides templates for ease of preparation. The sections require the following information be provided:
- Project Information
- Applicant Information
- Other Required Permits (if captured)
- Site Plan BMP Implementation Schedule
- plan sheets
- BMP locations
- schedule of site-specific BMPs implemented year round
- BMP information
- rationale for selecting BMP including, if needed, soil loss calculations
Important information to consider
- Most projects with disturbed soil that require a Building or Grading Permit must develop an Erosion and Sediment Control Plan (ESCP) and implement BMPs year-round.
- If an ESCP is required, a Building or Grading Permit will not be issued without written approval of the ESCP or Stormwater Pollution Prevention Plan.
- Prior to disturbing soil, provide evidence that all outside agency permits have been obtained.
- ESCP changes must be approved by the local permitting agency.
- Active projects must submit a revised ESCP for approval. Continue implementing current BMPs/Erosion and Sediment Control Plans until June 30, 2015.
- Applicants may need to consider BMPs beyond the minimum control measures if warranted by site conditions and planned construction activities.
- Projects subject to other permits (e.g., CGP, Section 404 Permit) must address the minimum MCSTOPPP control measures as well as the BMPs required by the other permit(s).
