Environmental Protection Agency June 20, 2007 – Federal Register Recent Federal Regulation Documents

The EPA is announcing that a workshop entitled ``Oxides of Nitrogen and Sulfur (NOX/SOX) Secondary National Ambient Air Quality Standards (NAAQS) Workshop'' is being organized by EPA's National Center for Environmental Assessment (NCEA), Office of Research and Development and EPA's Office of Air Quality Planning and Standards (OAQPS), Office of Air and Radiation. The workshop will be held on July 17, 18 and 19, 2007 in Research Triangle Park, North Carolina. The workshop will be open to attendance by interested public observers on a first-come, first-served basis up to the limits of available space.

EPA is proposing to make a determination under the Clean Air Act (CAA) that the nonattainment area of Dayton-Springfield, Ohio (Clark, Green, Miami, and Montgomery Counties) has attained the 8-hour ozone National Ambient Air Quality Standard (NAAQS). This determination is based on complete, quality-assured ambient air quality monitoring data for the 2004-2006 seasons that demonstrate that the 8-hour ozone NAAQS have been attained in the area. EPA is also proposing to approve, as a revision to the Ohio State Implementation Plan (SIP), the State's plan for maintaining the 8-hour ozone NAAQS through 2018 in the area. EPA is proposing to approve a request from the State of Ohio to redesignate the Dayton-Springfield area to attainment of the 8-hour ozone NAAQS. The Ohio Environmental Protection Agency (OEPA) submitted this request on November 6, 2006 and supplemented it on November 29, 2006, December 4, 2006, December 13, 2006, January 11, 2007, March 9, 2007, March 27, 2007, and May 31, 2007. EPA is also proposing to approve the State's 2005 and 2018 Motor Vehicle Emission Budgets (MVEBs) for the Dayton-Springfield area.

In the Federal Register of December 22, 2006, EPA issued a notice announcing its intent to approve an amended Colorado State Plan for the certification of applicators of restricted use pesticides contingent upon Colorado's promulgation of appropriate revised State Rules and Regulations pertaining to the Administration and Enforcement of the Colorado Pesticide Applicators' Act by January 1, 2007. In that notice, EPA solicited comments from the public on the proposed action to approve the amended Colorado State Plan. The amended Certification Plan Colorado submitted to EPA contained several statutory, regulatory, and programmatic changes to its current Certification Plan. The proposed amendments provide details for the certification of both private and commercial pesticide applicators and subsequent enforcement of pesticide laws and regulations pursuant to the Colorado Pesticide Applicator's Act. In addition, the amended State Plan adds three new commercial pesticide applicator subcategories. No comments were received in response to that Federal Register notice and Colorado promulgated the appropriate revised State Rules and Regulations pertaining to the Administration and Enforcement of the Colorado Pesticide Applicators' Act on January 1, 2007. Therefore, EPA hereby approves the amended Colorado State Plan.

The EPA is proposing to approve revisions to the New Mexico State Implementation Plan (SIP) that were submitted to EPA on April 11, 2002, and December 29, 2005. The proposed revisions modify New Mexico's Prevention of Significant Deterioration (PSD) and Nonattainment New Source Review (NNSR) regulations in the SIP to address changes to the Federal PSD and NNSR regulations, which were promulgated by EPA on December 31, 2002 and reconsidered with minor changes on November 7, 2003 (collectively, these two Federal actions are called the ``2002 New Source Review (NSR) Reform Rules''). The proposed revisions include provisions for baseline emissions calculations, an actual-to-projected- actual methodology for calculating emissions changes, options for plantwide applicability limits (PALs), and recordkeeping and reporting requirements. EPA is proposing to approve these revisions pursuant to section 110, parts C and D of the Federal Clean Air Act (Act).

EPA issued five notices in the Federal Register of May 2, 2007, announcing the availability and seeking comments on EPA's revised human health risk assessments for the fumigants chloropicrin, dazomet, 1,3-dichloropropene, metam potassium, metam sodium, and methyl bromide. This notice announces EPA's decision to extend the comment period from July 2, 2007 to September 3, 2007, for the five actions.

This notice announces receipt of an application 73049-EUP-U from Valent BioSciences Corporation requesting an experimental use permit (EUP) for the biochemical pesticide S-Abscisic Acid; (S)-5-(1- hydroxy-2,6,6-trimethyl-4-oxo-1-cyclohex-2-enyl)-3-methyl-pen ta- (2Z,4E)-dienoic Acid. The Agency has determined that the application may be of regional and national significance. Therefore, in accordance with 40 CFR 172.11(a), the Agency is soliciting comments on this application.
