Environmental Protection Agency May 30, 2007 – Federal Register Recent Federal Regulation Documents

Pursuant to the U.S. Environmental Protection Agency's (EPA or ``we'') Significant New Alternatives Policy (SNAP) program, this action proposes to list n-propyl bromide (nPB) as an unacceptable substitute for methyl chloroform, chlorofluorocarbon (CFC)-113, and hydrochlorofluorocarbon (HCFC)-141b when used in adhesives or in aerosol solvents because nPB in these end uses poses unacceptable risks to human health when compared with other substitutes that are available. In addition, EPA takes comment on alternate options that would find nPB acceptable subject to use conditions in adhesives or in aerosol solvents. This action also proposes to list nPB as acceptable, subject to use conditions, as a substitute for methyl chloroform, CFC- 113, and hydrochlorofluorocarbon (HCFC)-141b in the coatings end use. This proposal supersedes EPA's proposal of June 3, 2003 on the acceptability of nPB as a substitute for ozone-depleting substances for aerosols and adhesives.

EPA is proposing to approve a redesignation request and a State Implementation Plan (SIP) revisions submitted by the Commonwealth of Pennsylvania. The Pennsylvania Department of Environmental Protection (PADEP) is requesting that the Franklin County ozone nonattainment area (Franklin County Area) be redesignated as attainment for the 8-hour ozone national ambient air quality standard (NAAQS). EPA is proposing to approve the ozone redesignation request for Franklin County Area. In conjunction with its redesignation request, PADEP submitted a SIP revision consisting of a maintenance plan for Franklin County Area that provides for continued attainment of the 8-hour ozone NAAQS for at least 10 years after redesignation. EPA is proposing to make a determination that the Franklin County Area has attained the 8- hour ozone NAAQS, based upon three years of complete, quality-assured ambient air quality ozone monitoring data for 2003-2005. EPA's proposed approval of the 8-hour ozone redesignation request is based on its determination that the Franklin County Area has met the criteria for redesignation to attainment specified in the Clean Air Act (CAA). In addition, PADEP submitted a 2002 base year inventory for the Franklin County Area which EPA is proposing to approve as a SIP revision. EPA is also providing information on the status of its adequacy determination for the motor vehicle emission budgets (MVEBs) that are identified in the Franklin County Area maintenance plan for purposes of transportation conformity, which EPA is also proposing to approve. EPA is proposing approval of the redesignation request, and the maintenance plan and the 2002 base year inventory SIP revisions in accordance with the requirements of the CAA. EPA is also proposing to issue a determination that the area has attained the 1-hour ozone NAAQS, and to find that the requirements of section 172(c)(1) concerning the submission of the ozone attainment demonstration and reasonably available control measure requirements, the requirements of section 172(c)(2) concerning reasonable further progress (RFP), and the requirements of section 172(c)(9) concerning contingency measures for RFP or attainment do not apply to the area for so long as it continues to attain the 1-hour NAAQS for ozone.

Notice is hereby given that the State of Indiana is revising its approved Public Water System Supervision Program. Indiana has revised the following rules: Arsenic, Radionuclides, and Long Term 1 Enhanced Surface Water Treatment Rule. EPA has determined that these revisions by the State are no less stringent than the corresponding federal regulations. Therefore, EPA intends to approve these revisions to the State of Indiana's Public Water System Supervision Program. Any interested party may request a public hearing. A request for a public hearing must be submitted by June 29, 2007, to the Regional Administrator at the EPA Region 5 address shown below. The Regional Administrator may deny frivolous or insubstantial requests for a hearing. However, if a substantial request for a public hearing is made by June 29, 2007, EPA Region 5 will hold a public hearing. If EPA Region 5 does not receive a timely and appropriate request for a hearing and the Regional Administrator does not elect to hold a hearing on her own motion, this determination shall become final and effective on June 29, 2007. Any request for a public hearing shall include the following information: the name, address, and telephone number of the individual, organization, or other entity requesting a hearing; a brief statement of the requesting person's interest in the Regional Administrator's determination and a brief statement of the information that the requesting person intends to submit at such hearing; and the signature of the individual making the request, or, if the request is made on behalf of an organization or other entity, the signature of a responsible official of the organization or other entity.

EPA is proposing to approve revisions to the San Joaquin Valley Unified Air Pollution Control District (SJVUAPCD) portion of the California State Implementation Plan (SIP). These revisions concern Oxides of Nitrogen (NOX) emissions from Boilers, Steam Generators and Process Heaters (2.0 MMBtu/hr to 5.0 MMBtu/hr, and 0.075 MMBtu/hr to 2.0 MMBtu/hr); Dryers, Dehydrators, and Ovens; Natural Gas- Fired, Fan-Type Residential Central Furnaces; and Solid Fuel Fired Boilers, Steam Generators and Process Heaters. We are proposing to approve local rules to regulate these emission sources under the Clean Air Act as amended in 1990 (CAA or the Act).
