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.
