Asbestos Removal · Westmoreland County
Murrysville, a Westmoreland County home-rule municipality of 21,006 (2020 census), is where the Haymaker gas well of 1878 was drilled, described as the nation's first commercial natural gas well. Its population nearly doubled between 1960 (8,517) and 1980 (16,036), and as a Westmoreland town its asbestos rules come from PA DEP, not Allegheny County.
Murrysville is a Westmoreland County home-rule municipality, which means it sits outside the Allegheny County Health Department's asbestos program even though it borders Monroeville. Westmoreland has no county air program of its own. Asbestos here is regulated by the Pennsylvania Department of Environmental Protection's Southwest Regional Office under the federal rule, and DEP does not regulate removal from private residences unless the building is an apartment with five or more units. Pennsylvania's Labor and Industry certification law applies on both sides of the line.
Murrysville is where the Haymaker gas well was drilled in 1878, but its housing is far younger than that history. The population nearly doubled between 1960 and 1980, from 8,517 to 16,036, and Census estimates show about a third of its homes were built in those two decades, with only 4 percent before 1940. The median home dates from 1979. Plans like Murrysville Heights, Heather Highlands and Franklin Estates are large-lot houses of that era, where sprayed ceilings, floor tile on mastic, sheet vinyl and duct insulation are the materials to sample.
With 91 percent of homes owner-occupied and only 4 percent in buildings of five or more units, almost every residential job in Murrysville is outside DEP's rules. That does not make it unregulated. Anyone you hire for asbestos work must work for a contractor certified by the Department of Labor and Industry. For friable material over three square or three linear feet, the contractor files notice at least five days before work, and L&I can waive the wait in a genuine emergency such as a burst pipe in a lagged basement.
Commercial buildings along William Penn Highway are a different case. Each is a facility under the federal rule, so it must be inspected for asbestos before renovation or demolition. If the work will disturb at least 260 linear feet, 160 square feet or 35 cubic feet of friable asbestos, notice must reach DEP and EPA 10 working days ahead, and every facility demolition needs that notice regardless. DEP's notification fee outside Allegheny and Philadelphia counties rose to $400 in January 2026. Murrysville is about 35 minutes east of downtown via the Parkway East and Route 22. Common calls are textured ceilings and commercial pre-renovation surveys.
