Environmental Protection Agency May 11, 2011 – Federal Register Recent Federal Regulation Documents

EPA is amending the Toxic Substances Control Act (TSCA) section 8(a) Inventory Update Reporting (IUR) regulations by suspending the next IUR submission period. The IUR requires manufacturers (including importers) of certain chemical substances included on the TSCA Chemical Substance Inventory (TSCA Inventory) to report current data on the manufacturing, processing, and use of the chemical substances. In the Federal Register of August 13, 2010, EPA published proposed modifications to the IUR regulations. EPA is suspending the next submission period to allow additional time to finalize the proposed modifications to the IUR regulations, and to avoid finalizing changes to the reporting requirements in the midst of the 2011 submission period. EPA expects to finalize, in the near future, changes to the IUR reporting requirements which will supersede this action.

The EPA Science Advisory Board (SAB) Staff Office announces a public session on public involvement in activities related to the Advisory Council on Clean Air Compliance Analysis (the Council), Clean Air Scientific Advisory Committee (CASAC), and the SAB.

EPA is proposing to make two determinations regarding the tri- state Huntington-Ashland, West Virginia-Kentucky-Ohio fine particulate matter (PM2.5) nonattainment Area (hereafter referred to as ``the Huntington-Ashland Area'' or ``Area''). First, EPA is proposing to determine that the Area has attained the 1997 annual average PM2.5 National Ambient Air Quality Standard (NAAQS). This proposed determination of attainment is based upon complete, quality- assured and certified ambient air monitoring data for the 2007-2009 period showing that the Area has attained the 1997 annual PM2.5 NAAQS, and data available to date for 2010 in EPA's Air Quality System (AQS) database that show the area continues to attain. If EPA finalizes this proposed determination of attainment, the requirements for the Area to submit attainment demonstrations and associated reasonably available control measures (RACM), a reasonable further progress (RFP) plan, contingency measures, and other planning State Implementation Plan (SIP) revisions related to attainment of the standard shall be suspended for so long as the Area continues to attain the annual PM2.5 NAAQS. Second, EPA is also proposing to determine, based on quality-assured and certified monitoring data for the 2007-2009 monitoring period, that the Area has attained the 1997 annual PM2.5 NAAQS by its applicable attainment date of April 5, 2010.

This notice announces EPA's order for the amendments to terminate uses, voluntarily requested by the registrants and accepted by the Agency, of products containing ziram, diquat dibromide, and chloropicrin, pursuant to section 6(f)(1) of the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA), as amended. This cancellation order follows a December 1, 2010 Federal Register Notice of Receipt of Requests from the registrants listed in Table 2 of Unit II. to voluntarily amend to terminate uses of all these product registrations. These are not the last products containing these pesticides registered for use in the United States. In the December 1, 2010 notice, EPA indicated that it would issue an order implementing the amendments to terminate uses, unless the Agency received substantive comments within the 30-day comment period that would merit its further review of these requests, or unless the registrants withdrew their requests. The Agency did not receive any comments on the notice.
