Environmental Protection Agency June 29, 2012 – Federal Register Recent Federal Regulation Documents

The U.S. Environmental Protection Agency (EPA) is seeking nominations from a diverse range of qualified candidates to be considered for appointment as members of its Great Lakes Advisory Board (GLAB). The GLAB will provide advice and recommendations to the EPA Administrator, in her capacity as Chair of the Great Lakes Interagency Task Force, on matters pertaining to Great Lakes restoration and protection. Vacancies are expected to be filled by September 2012. Sources in addition to this Federal Register Notice may be used in the solicitation of nominees.

The U.S. Environmental Protection Agency's (EPA), Science Advisory Board (SAB) Staff Office announces a meeting of the SAB's Scientific and Technological Achievement Awards (STAA) Committee to discuss SAB recommendations regarding the Agency's 2012 STAA recipients. The SAB meeting will be closed to the public.

In this action we are proposing to approve into the Indiana State Implementation Plan (SIP) the addition of a new rule that sets volatile organic compound (VOC) emissions limits and other restrictions on consumer products that are sold, supplied, manufactured, or offered for sale in the State.

Based on its review of the air quality criteria and the national ambient air quality standards (NAAQS) for particulate matter (PM), the EPA proposes to make revisions to the primary and secondary NAAQS for PM to provide requisite protection of public health and welfare, respectively, and to make corresponding revisions to the data handling conventions for PM and ambient air monitoring, reporting, and network design requirements. The EPA also proposes revisions to the prevention of significant deterioration (PSD) permitting program with respect to the proposed NAAQS revisions. With regard to primary standards for fine particles (generally referring to particles less than or equal to 2.5 micrometers ([mu]m) in diameter, PM2.5), the EPA proposes to revise the annual PM2.5 standard by lowering the level to within a range of 12.0 to 13.0 micrograms per cubic meter ([mu]g/m\3\), so as to provide increased protection against health effects associated with long- and short-term exposures (including premature mortality, increased hospital admissions and emergency department visits, and development of chronic respiratory disease) and to retain the 24-hour PM2.5 standard. The EPA proposes changes to the Air Quality Index (AQI) for PM2.5 to be consistent with the proposed primary PM2.5 standards. With regard to the primary standard for particles generally less than or equal to 10 [mu]m in diameter (PM10), the EPA proposes to retain the current 24-hour PM10 standard to continue to provide protection against effects associated with short-term exposure to thoracic coarse particles (i.e., PM10-2.5). With regard to the secondary PM standards, the EPA proposes to revise the suite of secondary PM standards by adding a distinct standard for PM2.5 to address PM-related visibility impairment and to retain the current standards generally to address non-visibility welfare effects. The proposed distinct secondary standard would be defined in terms of a PM2.5 visibility index, which would use speciated PM2.5 mass concentrations and relative humidity data to calculate PM2.5 light extinction, translated to the deciview (dv) scale, similar to the Regional Haze Program; a 24-hour averaging time; a 90th percentile form averaged over 3 years; and a level set at one of two optionseither 30 dv or 28 dv.
