DEP reviewed a plan approval application—that was later modified—for the construction and initial operation of the facility. DEP’s review is highly technical and complex, requiring reviews and modeling by technical staff in DEP’s Southwest Regional Office and Harrisburg Central Office. After a thorough and complete review of the application and determination that the proposed activity can be done in a manner that complies with applicable rules and regulations—including the health-based National Ambient Air Quality Standards—DEP generates a plan approval that includes specific conditions, including monitoring and reporting.
