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.
