Venting Notification Registration

On November 16, 2020, the Maryland Department of the Environment (MDE) finalized Regulations .01 through .07 under COMAR 26.11.41 – Control of Methane from the Natural Gas Industry. The rules establish requirements to reduce vented and fugitive emissions of methane from both new and existing natural gas facilities in the transmission and storage sector.   

In the state of Maryland, Williams operates the Transco Compressor Station 190 as well as transmission pipeline assets. The compressor station, which is located in Ellicott City, Howard County, is an existing natural gas facility subject to the MDE Methane rule. 

Periodically, a natural gas venting event will occur at the compressor station. Venting events are typically scheduled to ensure safe operation and to perform equipment maintenance, inspection, or other activities. Transco works to minimize the need for venting where practical and reduce emissions where possible. 

Pursuant to COMAR 26.11.41.07. 07B(2)(b), Williams has developed a notification system to inform the MDE and the public of natural gas venting events in excess of one million standard cubic feet. Notifications will be generated in accordance with the Station’s MDE approved notification plan and will include the date and the approximate timeframe of each event. To receive email notifications about venting events at the Transco Natural Gas Compressor Station in Ellicott City, register by providing their name, email address, and affiliation (Resident, Organization, etc.).
