SUPPLEMENTARY INFORMATION:

I. Background

    The General Provisions to the Radionuclide NESHAP in 40 CFR part 
61, subpart A, require a source owner or operator to submit an 
application for approval of construction or modification, pursuant to 
40 CFR 61.07. Sources submitting applications in 2010 and 2011 
submitted them under this provision and include sources subject to 40 
CFR part 61, subpart B, National Emission Standards for Radon Emissions 
from Underground Uranium Mines (Subpart B) and 40 CFR part 61, subpart 
W, National Emission Standards for Radon Emissions from Operating Mill 
Tailings (Subpart W). EPA Region 8 issued three approvals in 2011 under 
60 CFR 61.08. Today's notice comprises a summary of the three 
approvals.
    The following summaries are for those Construction Approvals issued 
by EPA Region 8 during the 2011 calendar year; each summary provides 
the title of the Approval and a brief description. These summaries are 
provided solely to alert the public to possible items of interest and 
are not intended as substitutes for the full text of the Construction 
Approval. This notice does not change the status of any document with 
respect to whether it is ``of nationwide scope or effect'' for purposes 
of section 307(b)(1) of the Clean Air Act. For example, this notice 
does not make the Construction Approval for a particular source into a 
nationwide rule. Neither does it purport to make any document that was 
previously non-binding into a binding document.
