​​General Permit for Stormwater Associated with Construction Activity

General Permit For Discharges of Stormwater Associated With Construction Activity
Maryland General Permit No. 14-GP 

​​​The Maryland Department of the Environment (MDE) issued the General Permit for Stormwater Associated with Construction Activity, MDRC (General Permit), referred to as the 14-GP, which took effect on January 1, 2015.  

The permit is necessary to protect water quality and meet federal and State requirements under the Code of Federal Regulations (40 CFR 122.26 and 40 CFR 450) and the Code of Maryland Regulations (COMAR

NOTICE - 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 14-GP.  Proposed new discharges of stormwater associated with construction activity 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 of stormwater associated with construction activity if an applicant meets the 14-GP eligibility criteria and declares intention to operate in accordance with the terms of the Consent Order and 14-GP. The applicant should submit an NOI, completed in accordance with the requirements otherwise set forth for registrations under permit 14-GP, and a Declaration of Intent through the electronic registration/certification process on the ePermits website.




  • ePermits
    • The Notice of Intent (NOI) for this General Permit is submitted electronically through the ePermits website, as are Notices of Termination, Transfers, and the Declaration of Intent (DOI).
    • The NOI and DOI must be electronically signed by the person in authority from the developer or builder; however, the system will allow agents and consultants to prepare any part of the NOI necessary, then send it to the person who will submit it as the responsible party.
    • Federal regulations require that applicants must submit certain information to MDE to validate their authorization to submit an NOI on behalf of a responsible party.  To meet this requirement, MDE developed a Subscriber Agreement Template Form (.docpdf).
    • The ePermits system is hosted by MDE's contractor.  Should you encounter technical difficulties with the system, please access the resources listed on the 24/7 Support link at the top of the system screen.
    • If you have questions about an NOI or the General Permit, please contact MDE using the contacts at the bottom of this page.
