EPA Regulation Navigation Tools
NOTE: Landfills previously subject to Subpart WWW, Cc and Cf are now subject to Subpart OOO Federal Plan Requirements for Municipal Solid Waste Landfills. Therefore, the Subpart WWW, Cc and Cf Reg Nav tools are no longer applicable and have been removed from this page.
Regulation Navigation (Reg Nav) tools help owners and operators of facilities in certain industries determine the requirements of specific air quality regulations. Reg Nav tools are online and interactive, and use the information entered to assess potential regulatory requirements.
Reg Nav tools do not store or save information, so you must print or save any output that you want to use or reference. Note that the Reg Nav requirements may not be complete. Refer any questions to your local authority.
Try a different browser if you are having difficulties opening Reg Nav in one internet browser.
