OAR Policy and Guidance Information

Note: EPA no longer updates this information, but it may be useful as a reference or resource.


The OAR Policy and Guidance Web site is designed to provide access to rules, policy, and guidance documents produced by the USEPA Office of Air and Radiation (OAR). This site allows regulators, the regulated community and members of the general public to easily obtain access to both current and historical regulatory information. This site should make the task of understanding, implementing and complying with the requirements of the new enviromental regulations much easier.
