NAFTA Guidance for Conducting Terrestrial Field Dissipation Studies
Document Number: 05-11830
Type: Notice
Date: 2005-06-15
Agency: Environmental Protection Agency
Under the North American Free Trade Agreement (NAFTA), EPA and the Canadian Pest Management Regulatory Agency (PMRA) have agreed to harmonize their testing guidelines so that one set of tests can be used for the registration of pesticides in Canada and the United States. The NAFTA harmonized guidance for terrestrial field dissipation (TFD) studies are conducted to demonstrate the transformation, transport, and fate of pesticides under representative actual use conditions. These field studies are needed to substantiate the physicochemical, mobility, and biotransformation data from laboratory studies. Environmental fate studies have shown that pesticide dissipation may proceed at different rates under field conditions and may result in degradates forming at levels different from those observed in laboratory studies. The objective of this revised guidance document is to help ensure that TFD studies are conducted in a manner that will provide risk assessors and risk managers with more confidence in the data generated and with a better understanding of the assumptions and limitations of the data and estimated half-lives of the pesticide. The revised guidance can be found at: http://www.epa.gov/ oppefed1/ecoriskders/efedfinaldrafttfdguidance.pdf.
Approval and Promulgation of Implementation Plans and Designation of Areas for Air Quality Planning Purposes; Georgia, Redesignation of Atlanta Severe 1-Hour Ozone Nonattainment Area to Attainment for Ozone; Maintenance Plan; Motor Vehicle Emission Budgets; Revisions to Rules for Air Quality
Document Number: 05-11829
Type: Rule

Agency: Environmental Protection Agency
EPA is granting final approval of the 1-hour ozone redesignation request and the 10-year maintenance plan State Implementation Plan (SIP) revision, including the new 2015 Motor Vehicle Emission Budgets (MVEB) for the Atlanta severe 1-hour ozone National Ambient Air Quality Standard (NAAQS) nonattainment area, which were submitted by the Georgia Environmental Protection Division (EPD) on February 1, 2005. The current Atlanta severe 1-hour ozone nonattainment area consists of the following counties: Cherokee, Clayton, Cobb, Coweta, DeKalb, Douglas, Fayette, Forsyth, Fulton, Gwinnett, Henry, Paulding, and Rockdale (Atlanta area). EPA's approval of the 1-hour ozone redesignation request is based on our determination that the Atlanta area has met the criteria for redesignation to attainment specified in the Clean Air Act (CAA or Act), including a demonstration that the Atlanta area has attained the 1-hour ozone NAAQS. EPA is granting final approval of the 10-year maintenance plan SIP revision, including the new 2015 MVEB, because EPA has determined that the plan complies with the requirements of section 175A of the Act. For transportation purposes, EPA is also finalizing its adequacy determination for the new 2015 MVEB. EPA has determined that the MVEB for the year 2015 are adequate for transportation conformity purposes.
