Agency Milestone Date of 09/23/2025 for EPA authorizes discharge under Individual permit (Agency Action) has passed by 1 business days
Description:
The NPDES program is authorized by CWA: Section 402 (40 CFR Part 122). NPDES permits control discharges to waters of the U.S. The program ensures that discharges meet state water quality standards and other Clean Water Act requirements. A NPDES permit is required because the applicant proposes to withdraw cooling water from and discharge pollutants to the Atlantic Ocean from one or more offshore substations.
Milestones:
Ahead of this milestone, EPA recommends a pre-application meeting with the applicant prior to the milestone target date, to discuss expectations for the permit application, including information pertaining to the proposed cooling water intake structure (CWIS) in accordance with CWA Section 316(b), information required to evaluate the potential water quality impacts from the discharge of pollutants, including heat, in accordance with CWA Section 403(c) (Ocean Discharge Criteria), and monitoring/modeling information to support the permit application.
EPA will notify the applicant whether the application is complete or incomplete within 30 days from receiving the application. If incomplete, EPA will require the applicant to submit additional information necessary to make the application complete in accordance with 40 CFR 124.3(c).
Application must have all required elements, including those listed in 40 CFR 122.21.
The milestone will be checked (on the dashboard) when a complete application is submitted by the applicant.
Once the permit application addresses all applicable requirements, EPA will send notification to the applicant confirming that the permit application is complete. The Agency works towards a permit decision (issuance or denial) within one year. Prior to final decision, EPA offers a draft permit for public comment. The draft permit and all supporting information including the notice announcing the public comment period are made available on the EPA regional website. Relevant documents will also be uploaded to “Agency Postings” on the dashboard.

Description:
Updated February 2023: Mayflower Wind Project name changed to SouthCoast Wind Project.
The purpose of the SouthCoast Wind Project is to provide clean, renewable wind energy to the Northeast United States, including to Massachusetts. SouthCoast Wind will support reliability in Massachusetts and in the New England region, while meeting the Commonwealth’s statutory need for renewable/clean energy. The SouthCoast Wind Project also supports the federal need of grid reliability, as set forth the Federal Power Act in Section 215. Out of the 6.7 million people living in Massachusetts, nearly 5.1 million people live along coastal areas of the state. Offshore wind projects like SouthCoast Wind can provide a localized energy source to coastal populations.
