    This page was last updated on February 14, 2025.

    Site Background

    Westmoreland Sanitary Landfill, LLC (WSL) owns and operates a residual/municipal landfill of the same name located in Rostraver Township, Westmoreland County and County Hauling, a waste transportation company.

    What’s New

    On February, 15, 2025, DEP published a draft National Pollutant Discharge Elimination System (NPDES) permit for Westmoreland Sanitary Landfill. DEP is accepting comments on the draft discharge permit until April 3, 2025, and will hold a public hearing to receive testimony from the public. The application and associated documents can be found in the Permitting/Approval section below. 

    The public hearing will take place on March 20, 2025, from 6:00 PM to 8:30 PM at Rostraver Central Fire Department Social Hall, 1100 Fells Church Road, Rostraver Township, PA 15012.

    Permitting/Approvals

    Air quality plan approval is required for the applicant to commence construction of an air contamination source and may allow for temporary operation. A plan approval is not the same as an operating permit, which is required for long-term operation. Publication of a draft air quality plan approval and notice of intent signals that DEP has performed its evaluation of the application and begins the regulatory public participation process.

    On October 9, 2019, DEP received an air quality plan approval application on behalf of Westmoreland Sanitary Landfill for a proposed leachate evaporation system at the facility. On November 5, 2019, DEP accepted this application as administratively complete.

    On May 9, 2020, DEP issued a draft air quality plan approval.

    In response to public comments received, DEP has requested additional information from Westmoreland Sanitary Landfill. On July 2, 2020, DEP sent a letter to Westmoreland Sanitary Landfill requesting additional information. If Westmoreland Sanitary Landfill’s responses satisfied all deficiencies, DEP committed to develop a revised draft plan approval and review memo, republish public notice, provide for an additional public comment period, and hold a public hearing. Westmoreland Sanitary Landfill responded on August 31, 2020 and with additional information on September 23, 2020.

    On November 13, 2020, DEP sent Westmoreland Sanitary Landfill a second letter requesting additional information. Westmoreland Sanitary Landfill responded on February 4, 2021.

    On May 7, 2021, DEP sent Westmoreland Sanitary Landfill a third letter requesting additional information. On July 2, 2021, Westmoreland Sanitary Landfill requested an extension to respond to DEP’s deficiency letter. On July 20, 2021, DEP granted the extension to respond until September 2, 2021

    On July 15, 2021, DEP provided comments on the submitted air dispersion modeling protocol for the proposed installation of the leachate evaporator at Westmoreland Sanitary Landfill.

    On August 11, 2021, Westmoreland Sanitary Landfill submitted revised air dispersion modeling protocol to DEP. In coordination with DEP’s Southwest Regional Office and Bureau of Radiation Protection, DEP’s Air Quality Modeling Section reviewed the revised air dispersion modeling protocol for estimating ambient air concentrations of radionuclides due to the installation of the proposed leachate evaporator at Westmoreland Sanitary Landfill. DEP concurs with the proposed data, methods, and calculations to be used with the air dispersion modeling, as described in the protocol and will review the analysis when it is submitted.

    On October 1, 2021, Westmoreland Sanitary Landfill submitted additional information. On October 29, 2021, DEP’s air quality modeling section provided comments on Westmoreland Sanitary Landfill’s air dispersion modeling.

    Public Participation

    Public Notice on DEP’s proposed air quality plan approval was published in the July 23, 2020 edition of the Pennsylvania Bulletin, which began a public comment period.

    Due to a publishing error in the Mon Valley Independent, DEP has extended the comment period until through Friday, September 19, 2022.

    DEP accepted comments and held two public hearings – in person on Wednesday, August 31, 2022 and virtually on Thursday, September 1, 2022 – to receive comments on the draft plan approval.

    DEP provided an information sheet at the public hearings to provide background on the proposal and DEP’s review.

    On June 30, 2015, DEP approved the transfer of the landfill’s general permit from Tervita LLC to Westmoreland Sanitary Landfill, LLC.

    Since the transfer in ownership, DEP authorized a statewide NPDES general permit for stormwater discharges associated with industrial activity (PAG-03) which went into effect on September 24, 2016. The PAG-03 is renewed every five years and expires on September 23, 2021. Coverage under the PAG-03 serves as the existing permit for the facility and coverage under it is automatically extended. Landfills are covered by Appendix C.

    More information on the PAG-03 General Permit can be found on DEP’s webpage on industrial stormwater.

    DEP reviews NPDES applications in accordance with the federal Clean Water Act and Pennsylvania Clean Stream’s Law and establishes limits on what can be discharged, monitoring and reporting requirements, and other provisions to ensure that treated leachate and wastewater discharges from this facility do not pose a threat to public health or the environment. If DEP approves this individual NPDES permit application, it would replace the existing PAG-03 permit and the PAG-03 for this site would be terminated.

    On June 17, 2024, DEP received an individual NPDES permit application. On July 25, 2024, DEP identified technical deficiencies. On December 9, 2024, DEP received an updated sample results summary.
