Deep Creek Lake: Permit Renewal Application

The existing permit for the operation of Deep Creek Station, GA1992S009(08), is due to expire on April 1, 2019. On October 11, 2018, Brookfield Power Piney & Deep Creek Lake LLC applied to renew their permit. This application has been assigned permit application number GA 1992S009/09. The applicant seeks to renew their existing appropriation permit for the operation of the Deep Creek Station hydroelectric generation facility. This application seeks to increase an existing allocation from an annual average of 94,000,000 gallons per day (gpd) to 128,000,000 gpd. There is no proposed change to the maximum daily withdrawal of 420,000,000 gallons. The reason for the requested average annual increase is to account for higher flow volumes into Deep Creek Lake during years of high precipitation.

This proposed permit renewal may be of interest to many and documents related to the application process will be posted below as the application is reviewed. This review process will involve three meetings with representatives of the various stakeholders as described in "Package Sent from MDE to Applicatin (2019-Jan-15)" below. More information will be added as the review progresses.

Subcommittee on the Temperature Enhancement Protocol

A subcommittee was created to consider proposed changes to the protocol governing the Temperature Enhancement Releases (TERs) required by the currently effective permit for Deep Creek Station. The existing protocol is run to determine if a TER should be made to maintain the water temperature less than 25 Degrees C in the Youghiogheny River between the project tailrace and Sang Run, during the months of June, July, and August when a Whitewater Recreational Release (WWR) will not be made and the flow measured at USGS streamgage 03075500 (Youghiogheny River Near Oakland, MD) is less than 150 cubic feet per second (cfs). Revisions to be considered include, but are not limited to, extending the period during which the Temperature Enhancement Protocol will be run until September 15 and raising the flow limit at Oakland from less than 150 cfs to less than 180 cfs. (The proposal to start running the protocol in May has been dropped as not being justified by current measurements.) One meeting was held on August 1, 2019. Below are various presentations, documents, and selected correspondence relevant to that meeting.

A second meeting of the subcommittee has been scheduled for December 4, 2019 at 10:30 AM at Garrett College, Room 103 of the Continuing Education Workforce Development building, which is shown on this map. We do not yet have an agenda for this meeting, but will post the agenda when we do.
