Methane Mitigation Project Approved for Closed Maryland Landfill

The mitigation system involves a trench and vents.

A project to mitigate landfill seeping from the closed City County Landfill near Hagerstown, Md., has been approved.

The mitigation system involves a trench and vents that will stop the methane from continuing to migrate onto adjacent properties and vent the gas into the air.

That landfill opened in 1960 and closed in 1982. has more:

The Washington County Board of Commissioners voted 3-0 on Tuesday to award the mitigation construction contract to Sterns, Conrad and Schmidt Consulting Engineers of Reston, Va., for the low bid of $1,287,641. Three bids were received, according to a county presentation document.

As required, the county has monitored the site for years, Mason said.

A 2015 gas study determined the existence and extent of gas migration at the city/county landfill and recommended a mitigation system be built, according to the county's capital improvement plan.
Mason said he hopes the work starts in early February and it shouldn't take the four months allowed.
