Delmarva Power Restores Site of 19th Century Manufactured Gas Plant in Cambridge, Md.

Friday, November 14, 2008

CAMBRIDGE, Md. – As part of its commitment to protect the environment and be a good neighbor in the communities it serves, Delmarva Power recently completed environmental remediation work on its unoccupied Cherry Street property on the west bank of Cambridge Creek. An 1860s-era manufactured gas plant was once located on the site.

“We made sure that the extensive remediation process did not adversely affect the health and safety of workers, nearby residents and visitors to Cambridge,” said Wes McNealy, Manager of Corporate Environmental Services for Delmarva Power, upon completion of the project. “Returning properties to productive use in a clean and safe manner not only has obvious environmental benefits, but can possibly produce economic benefits as well.”

“This project completes the requirements set forth in an environmental agreement,” said Horacio Tablada, Director of the Waste Management Program at the Maryland Department of the Environment. “Delmarva Power’s efforts in carrying out the cleanup on both the land and water are an example of how Maryland’s environment can be improved for everyone.”

“I want to personally thank Delmarva Power for being proactive in undertaking the cleanup of the manufactured gas plant site and for doing so in a way that took into consideration the health and safety of our town’s residents,” said Cambridge Mayor Victoria Jackson-Stanley.

An environmental analysis conducted several years ago indicated that remediation work on the site was necessary. This work involved the removal of gas plant structures, tanks and affected soil from the land and sediments from Cambridge Creek. Delmarva Power has not yet developed a plan for future use of the property.

In the days before natural gas wells and pipelines criss-crossed the country to deliver gas to residential and commercial customers, many communities were served by gas plants that used coal, coke and oil as raw materials to produce gas for lighting, cooking, heating and industrial uses.
