n-Butyl 3-hydroxybutyrate and Isopropyl 3-hydroxybutyrate; Exemption From the Requirement of a Tolerance
This regulation establishes exemptions from the requirement of a tolerance for residues of n-butyl 3-hydroxybutyrate (CAS Reg. No. 53605-94-0) and isopropyl 3-hydroxybutyrate (CAS Reg. No. 54074-94-1) when used as inert ingredients (solvents) in pesticide formulations applied to growing crops or raw agricultural commodities after harvest; to animals; and to food contact surfaces in public eating places, dairy-processing equipment, and food-processing equipment and utensils. Steptoe and Johnson, on behalf of Eastman Chemical Company, submitted a petition to EPA under the Federal Food, Drug, and Cosmetic Act (FFDCA), requesting establishment of these exemptions from the requirement of a tolerance. This regulation eliminates the need to establish a maximum permissible level for residues of n-butyl 3-hydroxybutyrate and isopropyl 3-hydroxybutyrate when applied or used under these conditions.
Partial Stay; Arizona; Regional Haze Federal Implementation Plan
The Environmental Protection Agency (EPA) is granting an administrative stay of specific provisions of the Arizona Regional Haze Federal Implementation Plan (FIP) applicable to the Phoenix Cement Company (PCC) Clarkdale Plant and the CalPortland Company (CPC) Rillito Plant under the Clean Air Act (CAA). In response to requests from PCC and CPC, we are staying the effectiveness of control technology optimization requirements for nitrogen oxides (NOX) applicable to Kiln 4 at the Clarkdale Plant and Kiln 4 at the Rillito Plant during the EPA's reconsideration of these requirements under CAA section 307(d)(7)(B) for a period of 90 days. Today's action reflects this stay in the Code of Federal Regulations.
Approval of Iowa's Air Quality Implementation Plans; Regional Haze State Implementation Plan Revision and 2013 Five-Year Progress Report
The Environmental Protection Agency (EPA) is taking final action to approve the Iowa State Implementation Plan (SIP) revision submitted to EPA by the State of Iowa on July 19, 2013, documenting that the State's existing plan is making adequate progress to achieve visibility goals by 2018. The Iowa SIP revision addressed the Regional Haze Rule (RHR) requirements under the Clean Air Act (CAA or Act) to submit a report describing progress in achieving reasonable progress goals (RPGs) to improve visibility in Federally designated areas in nearby states that may be affected by emissions from sources in Iowa. EPA is taking final action to approve Iowa's determination that the existing Regional Haze (RH) SIP is adequate to meet the visibility goals and requires no substantive revision at this time.
Finding That Greenhouse Gas Emissions From Aircraft Cause or Contribute to Air Pollution That May Reasonably Be Anticipated To Endanger Public Health and Welfare
In this action, the Administrator finds that elevated concentrations of greenhouse gases in the atmosphere endanger the public health and welfare of current and future generations within the meaning of section 231(a)(2)(A) of the Clean Air Act (CAA, or Act). She makes this finding specifically with respect to the same six well-mixed greenhouse gasescarbon dioxide (CO2), methane, nitrous oxide, hydrofluorocarbons, perfluorocarbons, and sulfur hexafluoride that together were defined as the air pollution in the 2009 Endangerment Finding under section 202(a) of the CAA and that together constitute the primary cause of the climate change problem. The Administrator also finds that emissions of those six well-mixed greenhouse gases from certain classes of engines used in certain aircraft are contributing to the air pollutionthe aggregate group of the same six greenhouse gasesthat endangers public health and welfare under CAA section 231(a)(2)(A).
