Existing Permit - General Discharge Permit No. 15-MM (NPDES No. MDG49)
The 15-MM general permit became effective on May 1, 2017.
Change in Required Documentation
In recognition that the permit is beyond its five-year term, and in recognition that NPDES permits have a maximum duration of five years, the Department is discontinuing the acceptance of new registrations under permit 15-MM. Proposed new discharges from mineral mines, quarries, borrow pits, and concrete and asphalt plants submitted will not be allowed to obtain general permit coverage until a new permit is issued.
In place of permit coverage under the expired permit, the Department has issued an Order to cover proposed new discharges from mineral mines, quarries, borrow pits, and concrete and asphalt plants if an applicant meets the 15-MM eligibility criteria and declares intention to operate in accordance with the terms of the Consent Order and 15-MM. The applicant should submit a Declaration of Intent and complete the registration/certification process in accordance with the requirements otherwise set forth for registrations under permit 15-MM.
Note that existing registrations under the General Permit 15-MM continue to be covered under the existing administratively extended permit (per the terms of the permit). Please check back here for updates as progress is made towards that end or sign up for our newsletter. Once a draft of the new permit has been proposed to open the public participation process, the Department will take comments prior to arriving at a final permit.
