Sewage Sludge Incinerators (SSI)

See for current combustion actions

The purpose of this page is to provide information regarding EPA's air emission regulations for Sewage Sludge Incinerators (SSI). Information is categorized into four groups as follows: (1) Rule Information, (2) Technical Information, (3) Implementation Information, or (4) Related Web Sites. Descriptions of (and direct links to) these areas are provided below.

Rule Information -- This area contains Federal Register notices for both proposed and promulgated (final) rules.   The Federal Register notices summarize the basis of the rules and include the actual regulatory text.   In addition, an update on the litigation and links to closely related rules, policies, or program guidance are provided here.

Technical Information -- This area contains technical information used in developing the rules.   Background documents are available for download.   In addition, fact sheets which summarize the requirements of the rules are available here.

Implementation Information -- This area contains implementation information including guidance for States and, when available, the current status of State Plans.   In addition, compliance and enforcement information is provided here.

Related Web Sites -- This area provides links to other web sites where additional information may be found.
