Rule and Implementation Information for New Source Performance Standards (NSPS)
for Boilers (Steam Generating Units)
EPA-HQ-OAR-2005-0031
(Legacy Dockets
# A-79-02, A-83-27, A-86-02, and A-92-71)
The purpose of this page is to provide information regarding EPA's air emission regulations for Boilers (Steam Generating Units). This page is focused on New Source Performance Standards (NSPS) limiting SO2, PM, and NOx emissions from boilers built after certain dates. A separate web page has been created to address toxic air emissions from boilers.
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, the actual regulatory text is available as it appears in the Code of Federal Regulations, 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. Compliance and enforcement information is provided here.
Related Web Sites -- This area provides links to other web sites where additional information may be found.

Technical Information
Background Information Document (BID)/Response to Comments
Because the boiler NSPS were developed in the 1970's and 1980's, very little information is available electronically. All of the materials considered by EPA in developing the rules are available in Dockets A-79-02 (Subpart Db), A-83-27 (Subpart Db), A-86-02 (Subpart Dc), and A-92-71 (Da/Db NOx Amendment) for public inspection and copying by calling or visiting EPA's Air and Radiation Docket and Information Center (the Docket Office). A reasonable fee may be charged for copying. The telephone number for the Docket Office is 202-260-7548.
Reports identified with an EPA number (e.g., EPA-453/R-94-042a)
are also available (for a fee) through the National Technical Information
Service (NTIS). NTIS documents are identified by a publication
number (e.g., PB95-193116INZ). To order through NTIS, call
1-800-553-6847 or fax (703) 321-8547 or email orders@ntis.fedworld.gov
