Local Enforcement Starts June 8, 2026
The Allegheny County Health Department (ACHD) is delegated to implement and enforce the Federal plan for existing sewage sludge incineration (SSI) units in Allegheny County, with the delegation effective June 8, 2026. The EPA signed the Memorandum of Agreement on June 17, 2025 and retains enforcement authority alongside ACHD.
Federal Plan Requires Lower Emissions
The Federal plan for existing SSI units imposes emission limits and control requirements that will reduce designated pollutants from affected SSI facilities. The delegation transfers responsibility to ACHD to implement those Federal-plan emission limits for Allegheny County sources.
No New Requirements; Small Entities Not Impacted
The delegation does not add requirements beyond the existing Federal Plan and the EPA certified this action will not have a significant economic impact on a substantial number of small entities. The EPA states that the ACHD will regulate a single entity in Allegheny County and that the facility with the SSI unit is not a small entity.
Which SSI Units Are Covered (Key Dates)
The delegation and Federal plan apply in Allegheny County to SSI units that meet Sec. 62.15855 criteria: units that commenced construction on or before October 14, 2010, or that commenced physical or operational changes on or before September 21, 2011 to comply with 40 CFR part 62, subpart LLL; that meet the SSI definition in Sec. 62.16045; and that are not exempt under Sec. 62.15860.
