The Details

What you need

A general permit is not tailored to a specific facility but rather written to cover multiple dischargers with similar operations and types of discharges. Once issued, dischargers may request coverage, consistent with the permit eligibility and authorization provisions. Dischargers covered under general permits know their applicable requirements before obtaining coverage under that permit. In order to request coverage, an applicant must submit a Notice of Intent (NOI) to EPA and may also, depending on circumstances described below, need to apply to MassDEP.

This permit category replaces WM 08, 09, 10, 11, 12, 13, and 14.

In general, NPDES permits must be applied for and obtained by:

  • Any agency or political subdivision of the Commonwealth
  • Any federal agency
  • Any public or private:
    • corporation
    • authority
    • individual
    • partnership
    • association, or
    • other entity

proposing to discharge wastewater from a point source to surface water must apply to EPA. The following situations require applicants to submit a copy of EPA’s Notice of Intent (NOI) to MassDEP, along with transmittal form and payment (unless exempt):

  • POTW General Permit: all applicants
  • Dewatering General Permit: Discharges to an Outstanding Resource Water or Class SA Water
  • All other general permits: discharges to an Outstanding Resource Water.
