Environmental Protection Agency April 6, 2012 – Federal Register Recent Federal Regulation Documents

This document proposes to establish a tolerance for residues of methyl bromide in or on cotton, undelinted seed under the Federal Food, Drug, and Cosmetic Act (FFDCA) because there is a need for imported undelinted cottonseed for use as feed for dairy cattle in the United States. This imported cottonseed has become necessary because cottonseed is a critical part of the dairy cattle diet and the 2011 U.S. cotton crop was significantly below average due to severe drought conditions in Texas.

The U.S. Environmental Protection Agency (EPA) is announcing the availability of literature searches for acetaldehyde (75-07-0) and 1,2,3-trimethlybenzene (526-73-8). EPA is requesting scientific information on health effects that may result from exposure to these chemical substances. EPA's IRIS is a human health assessment program that evaluates quantitative and qualitative risk information on effects that may result from exposure to specific chemical substances found in the environment.

EPA is partially approving and partially disapproving a revision to the North Dakota State Implementation Plan (SIP) addressing regional haze submitted by the Governor of North Dakota on March 3, 2010, along with SIP Supplement No. 1 submitted on July 27, 2010, and part of SIP Amendment No. 1 submitted on July 28, 2011. These SIP revisions were submitted to address the requirements of the Clean Air Act (CAA or Act) and our rules that require states to prevent any future and remedy any existing man-made impairment of visibility in mandatory Class I areas caused by emissions of air pollutants from numerous sources located over a wide geographic area (also referred to as the ``regional haze program''). EPA is promulgating a Federal Implementation Plan (FIP) to address the gaps in the plan resulting from our partial disapproval of North Dakota's Regional Haze (RH) SIP. In addition, EPA is disapproving a revision to the North Dakota SIP addressing the interstate transport of pollutants that the Governor submitted on April 6, 2009. We are disapproving it because it does not meet the Act's requirements concerning non-interference with programs to protect visibility in other states. To address this deficiency, we are promulgating a FIP.
