Environmental Protection Agency March 6, 2013 – Federal Register Recent Federal Regulation Documents

The EPA Science Advisory Board (SAB) Staff Office announces a public teleconference of the chartered SAB to conduct a quality review of an SAB draft report on approaches to derive a maximum contaminant level goal for perchlorate.

This notice announces the availability of EPA's draft human health and ecological risk assessments for the registration review of cyromazine, silica silicates (silica dioxide and silica gel), glufosinate ammonium, dioctyl sodium sulfosuccinate (DSS) and undecylenic acid (UDA) and opens a public comment period on these documents. Registration review is EPA's periodic review of pesticide registrations to ensure that each pesticide continues to satisfy the statutory standard for registration, that is, the pesticide can perform its intended function without unreasonable adverse effects on human health or the environment. As part of the registration review process, the Agency has completed draft risk assessments for each of the subject chemicals and is making them available for public comment. After reviewing comments received during the public comment period, EPA will issue a revised risk assessment, if appropriate, explain any changes to the draft risk assessment, and respond to comments and may request public input on risk mitigation. Through this program, EPA is ensuring that each pesticide's registration is based on current scientific and other knowledge, including its effects on human health and the environment.

Under 122(g)(4) of the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA), the United States Environmental Protection Agency has entered into a settlement at the Ward Transformer Superfund Site located in Raleigh, Wake County, North Carolina. Under the terms of the De Minimis Landowner Settlement Agreement B&B Apartments, LLC, agrees to sell the property and B&B Apartments, LLC, and Estes Express Lines, Inc., agree to provide access, implement/comply with institutional controls, and exercise due care and cooperation for such time as they own or lease the property in exchange for the covenant not to sue and contribution protection provided in the Settlement Agreement.

EPA is taking final action to approve in part, and conditionally approve in part, the State Implementation Plan (SIP) submission, submitted by the State of Tennessee, through the Tennessee Department of Environment and Conservation (TDEC), to demonstrate that the State meets the infrastructure requirements of Clean Air Act (CAA or Act) for the 2008 8-hour ozone national ambient air quality standards (NAAQS). The CAA requires that each state adopt and submit a SIP for the implementation, maintenance, and enforcement of each NAAQS promulgated by EPA, which is commonly referred to as an ``infrastructure'' SIP. On October 19, 2009, TDEC made a SIP submission to certify that the Tennessee SIP already contains provisions that ensure the 2008 8-hour ozone NAAQS are implemented, enforced, and maintained in Tennessee (hereafter referred to as ``infrastructure submission''). On March 23, 2012, TDEC submitted a letter requesting conditional approval of the infrastructure submission with respect to the requirements in its SIP applicable to state boards. On October 4, 2012, Tennessee submitted a letter requesting conditional approval of infrastructure submission with respect to requirements in its SIP with respect to requirements applicable to its permitting program for prevention of significant deterioration (PSD) increments. With the exception of elements pertaining to PSD increments and state board requirements, Tennessee's infrastructure submission, provided to EPA on October 19, 2009, addresses all the applicable infrastructure SIP requirements for the 2008 8-hour ozone NAAQS. At this time, there are no outstanding infrastructure submission requirements for Tennessee with respect to significant contribution to nonattainment or interference with maintenance of the 2008 8-hour ozone NAAQS.

The Association of American Pesticide Control Officials (AAPCO)/State FIFRA Issues Research and Evaluation Group (SFIREG), Pesticide Operations and Management (POM) Committee will hold a 2-day meeting, beginning on April 22, 2013, and ending April 23, 2013. This notice announces the location and times for the meeting and sets forth the tentative agenda topics.
