Sewage Sludge Incineration Units (SSI): New Source Performance Standards (NSPS) and Emission Guidelines (EG)

Rule Summary

Section 129 of the Clean Air Act (CAA), titled, “Solid Waste Combustion,” requires the EPA to develop and adopt standards for solid waste incineration units pursuant to CAA sections 111 and 129.

This suite of actions promulgate EPA’s new source performance standards (NSPS), emission guidelines (EG), and federal implementation plan (FIP) for sewage sludge incineration units (SSI) located at wastewater treatment facilities designed to treat domestic sewage sludge. These final rules set limits for nine pollutants under CAA section 129:

  • Cadmium,
  • carbon monoxide,
  • hydrogen chloride,
  • lead,
  • mercury,
  • nitrogen oxides,
  • particulate matter,
