Environmental Protection Agency May 31, 2012 – Federal Register Recent Federal Regulation Documents

EPA is taking direct final action to approve Illinois' negative declaration and request for EPA withdrawal of its 111(d)/129 State Plan to control air pollutants from ``Large Municipal Waste Combustors'' (LMWC).

In compliance with the Paperwork Reduction Act (PRA)(44 U.S.C. 3501 et seq.), this document announces that EPA is planning to submit a request to reinstate an Information Collection Request (ICR) to the Office of Management and Budget (OMB). This ICR expired on January 31, 2011. Before submitting the ICR to OMB for review and approval, EPA is soliciting comments on specific aspects of the proposed information collection as described below.

Pursuant to section 107(d)(3) of the Clean Air Act, the EPA is redesignating from ``unclassifiable'' to ``nonattainment'' an area in western Pinal County, Arizona, for the 1987 national ambient air quality standard for particles with an aerodynamic diameter less than or equal to a nominal 10 micrometers (PM10), and therefore also revising the boundaries of the existing ``rest of state'' unclassifiable area. The EPA's establishment of this new PM10 nonattainment area, referred to as ``West Pinal,'' is based on numerous recorded violations of the PM10 standard at various monitoring sites within the county. With the exception of Indian country and certain Federal lands, the EPA's nonattainment area boundaries generally encompass the land geographically located within Pinal County north of the east-west line defined by the southern line of Township 9 South, Gila and Salt River Baseline and Meridian, and west of the north-south line defined by the eastern line of Range 8 East, except where the boundary extends farther east in the Florence and Picacho Peak areas. The effect of this action is to establish and delineate a new PM10 nonattainment area within Pinal County and thereby to impose certain planning requirements on the State of Arizona to reduce PM10 concentrations within this area, including, but not limited to, the requirement to submit, within 18 months of redesignation, a revision to the Arizona state implementation plan that provides for attainment of the PM10 standard as expeditiously as practicable but no later than the end of the sixth calendar year after redesignation.

EPA is withdrawing a significant new use rule (SNUR) promulgated under the Toxic Substances Control Act (TSCA) for a chemical substance identified generically as C15 olefins, which was the subject of premanufacture notice (PMN) P-11-511. EPA published this SNUR using direct final rulemaking procedures. EPA received a notice of intent to submit adverse comments on the rule. Therefore, the Agency is withdrawing this SNUR, as required under the expedited SNUR rulemaking process. EPA intends to publish a proposed SNUR for the chemical substance under separate notice and comment procedures.
