BACKGROUND:
In 2011, the EPA finalized new source performance standards and emission guidelines for new and existing Sewage Sludge Incinerator (SSI) units located at publicly owned wastewater treatment works. These standards are based on Maximum Available Control Technology (MACT) provisions of the Clean Air Act Section 129, subjecting SSIs to more stringent air emission requirements. The regulations, as currently set forth, set a time limit of March 21, 2016 for demonstrating emissions compliance. For purposes of applying the rule both SSIs at the TZ Osborne facility are classified as "existing" units and therefore subject to less restrictive emission limits.
In order to meet the new SSI emission limits using technology with a proven ability i...
