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.

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     Visit the NTIS Website   to search for additional documents.
