On June 3, 2020, the U.S. EPA's 2015 Multi-Sector General Permit (MSGP) for Stormwater Discharges Associated with Industrial Activity expired. EPA is the permitting authority for the National Pollutant Discharge Elimination System (NPDES) permitting system under which this general permit is promulgated in several US states and territories, as shown in the below graphic. Any facility currently registered to discharge industrial stormwater under EPA's authority in those locations is most likely authorized via this expiring mechanism.
EPA has informed facilities previously registered under the 2015 MSGP that the agency was not be able to issue a new permit prior to the expiration date. However, in accordance with the Administrative Procedure Act and 40 CFR 122.6, EPA has administratively continued the 2015 MSGP. It currently remains in effect for discharges that were covered prior to expiration.
All facilities registered under the 2015 MSGP will automatically remain covered until EPA issues a new MSGP. Facilities that have active permit coverage or submitted a Notice of Intent (NOI) to apply for coverage under the 2015 MSGP prior to June 3, 2020, do not need to take any further action to remain covered by the administratively continued 2015 MSGP. Each facility's coverage status in the NPDES eReporting Tool Multi-Sector General Permit (NeT MSGP) was automatically updated to "Admin. Continued" on the expiration date of the permit. There is no change to the compliance requirements of the MSGP under the administratively continued permit and each facility must continue to comply in full.
When EPA issues the new MSGP, all existing facilities will be notified via email through the NeT MSGP system. Within 90 days of the effective date of the new MSGP, each facility will be required to re-assess their applicability to apply for coverage under the general permit and submit an updated NOI to obtain coverage under the new MSGP.
