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. This application was determined to be administratively complete on November 5, 2019.
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.
DEP has not made decision on the application. 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.
DEP issued a draft Air Quality Plan Approval on May 9, 2020.
On July 2, 2020, DEP sent a letter to Westmoreland Sanitary Landfill requesting additional information.
On November 13, 2020, DEP sent Westmoreland Sanitary Landfill a second letter requesting additional information. Westmoreland Sanitary Landfill responded on February 4, 2021.
Public Notice on DEP’s proposed air quality plan approval was published in the May 9, 2020 edition of the
Pennsylvania Bulletin, which began a 30-day public comment period.
More info (begins on page 2423).
In response to public comments received, DEP has requested additional information from Westmoreland Sanitary Landfill. DEP will not take a final action on the plan approval application while it awaits a response from the landfill. If DEP makes significant changes to its draft plan approval as a result of its review of the additional data submitted, DEP will republish notice in the
Pennsylvania Bulletin, provide relevant documents on this webpage, and provide an additional public comment period.

Landfills are covered by Appendix C.
