Subpart W Rulemaking Activity
NESHAP Subpart W is a radon emission standard for operating uranium mill tailings. In accordance with the Clean Air Act Amendments of 1990, EPA has formed a workgroup to review, and possibly revise the standard. EPA invites and encourages the public to provide comments on our review of Subpart W.
As the Workgroup on Subpart W develops its tentative rulemaking, we will provide up-to-date information on recent or upcoming conference calls, resource documents, and contact information. Please check back regularly, as more items will be added.

Public Participation by E-Mail
EPA welcomes public participation in the review of Subpart W. We are interested in hearing about issues that you think EPA should address in the rule, as well as any thoughts you may have on the review and rulemaking process. You may submit your thoughts and read what others have submitted on our message page.
Conference Call Information
EPA will hold quarterly conference calls with interested stakeholders. The next conference call will occur on Thursday, April 3, 2014 at 11 AM EDT, 10am CDT, 9am MDT and 8am PDT. The call in number is 1-866-299-3188. You will be prompted for a conference code, which will be 2023439563. After entering the conference code press the # key and you will then be placed into the conference call.

Mine Location Database
EPA worked with the multi-agency Colorado Plateau Data Coordination Group Steering Committee to develop a geographic information database on uranium mines and mills. (The Agency also coordinated this effort with federal, state, and tribal agencies in other parts of the western U.S.)
The database identifies and shows the location of active and inactive uranium mines and mills, as well as mines which principally produced other minerals, but were known to have uranium in the ore. The database covers mine locations in fourteen western states. It also contains other information about the sites. Originally compiled as an important component of the uranium mining technical reports currently being developed, the database was reviewed and checked for its quality to eliminate duplicate and erroneous sites, and subjected to EPA’s scientific peer review process.
The database and descriptive materials about its content are now available.
