Environmental Protection Agency October 8, 2014 – Federal Register Recent Federal Regulation Documents

The U.S. Environmental Protection Agency (EPA) is announcing a public meeting of the National Drinking Water Advisory Council (NDWAC) Lead and Copper Rule Working Group (LCRWG). The meeting is scheduled for November 12 and 13, 2014, in Arlington, VA. During this meeting, the LCRWG and the EPA will focus discussions on the Lead and Copper Rule revision issues associated with lead service line replacements.

EPA issued final significant new use rules (SNURs) in the Federal Register of September 2, 2014 for 36 chemical substances which were the subject of premanufacture notices (PMNs). For the chemical substance identified generically as diisocyanate terminated polycarbodiimide (PMN P-04-640), EPA inadvertently omitted the de minimus exemption from the worker protection requirements. Also, for the chemical substance identified generically as hexanedioic acid, polymer with .alpha.-hydro-.omega.- hydroxypoly[oxy(methyl-1,2- ethanediyl)],1,1'-methylenebis[4-isocyanatobenzene], dihydroxydialkyl ether and dialkanol ether (PMN P-11-311) a typographical error in the PMN number has been identified. The amendments in this document are being issued to correct the omission and the typographical error.

With this document, the U.S. Environmental Protection Agency (EPA, or the Agency) approves the U.S. Department of Energy's (DOE, or the Department) planned change request to implement the Run-of-Mine Panel Closure System (ROMPCS) at the Waste Isolation Pilot Plant (WIPP) and amends the WIPP Compliance Criteria to allow an EPA-approved panel closure other than the currently-required Option D design. Technical analyses demonstrate that, with the modified panel closure design, WIPP remains in compliance with the 10,000 year release limits set by the ``Environmental Standards for the Management and Disposal of Spent Nuclear Fuel, High-Level and Transuranic (TRU) Radioactive Waste.'' The changes do not lessen the requirements for complying with the Compliance Criteria, nor do these changes impact the technical approach that the EPA will employ when considering any future planned changes to the panel closure system. Compliance with environmental or public health regulations other than the EPA's long-term radioactive waste disposal regulations and WIPP Compliance Criteria is not addressed by today's action.

Florida has applied to the Environmental Protection Agency (EPA) for final authorization of changes to its hazardous waste program under the Resource Conservation and Recovery Act (RCRA). These changes correspond to certain Federal rules promulgated between July 1, 2007 and June 30, 2009, and July 1, 2010 and June 30, 2011 (also known as RCRA Clusters XVIII, XIX and XXI). With this proposed rule, EPA is proposing to grant final authorization to Florida for these changes. Along with this proposed rule, EPA is publishing an immediate final rule in the ``Rules and Regulations'' section of today's Federal Register pursuant to which EPA is authorizing these changes. EPA did not issue a proposed rule before today because EPA believes this action is not controversial and does not expect comments that oppose it. EPA has explained the reasons for this authorization in the immediate final rule. Unless EPA receives written comments that oppose this authorization during the comment period, the immediate final rule in today's Federal Register will become effective on the date it establishes, and EPA will not take further action on this proposal. If EPA receives comments that oppose this action, EPA will withdraw the immediate final rule and it will not take effect. EPA will then respond to public comments in a later final rule based on this proposed rule. You may not have another opportunity to comment on these State program changes. If you want to comment on this action, you must do so at this time.

This action finalizes the residual risk and technology review (RTR) conducted for the Acrylic and Modacrylic Fibers Production, Amino/Phenolic Resins Production and Polycarbonate Production source categories regulated under national emission standards for hazardous air pollutants (NESHAP). In addition, we are taking final action addressing emissions during periods of startup, shutdown and malfunction, and are adding standards for previously unregulated hazardous air pollutant (HAP) emissions sources for certain emission points. These changes include revisions made in response to comments received on the proposed rule. These final amendments also include clarifying provisions pertaining to open-ended valves and lines, adding monitoring requirements for pressure relief devices and adding requirements for electronic reporting of performance test results, as proposed. We estimate that these final amendments will reduce HAP emissions from these three source categories by a combined 137 tons per year.
