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.

Compliance and Enforcement Information

Applicability Determination Index (ADI).   The ADI is maintained by EPA's Office of Enforcement and Compliance Assurance (OECA) and provides a data base of memoranda dealing with applicability issues.   The database is searchable by Subpart.

Emissions Measurement Center. The Emission Measurement Center (EMC) provides information on test methods for measuring pollutants from smokestacks and other industrial sources. This site compiles the test methods available for emission measurement, and EMC staff provide technical assistance in the use and application of the methods.
