Final Rule World Trade Center Health Program; Certification of Breast Cancer in WTC Responders and Survivors Exposed to PCBs On September 12, 2012, HHS published a final rule in the Federal Register adding certain types of cancer to the List of World Trade Center (WTC)-Related Health Conditions (List) established in the WTC Health Program regulation. Breast cancer was included on the List, although only individuals experiencing nighttime sleep disruption as a result of response and cleanup activities involving shiftwork are currently considered to have experienced exposure relevant for certification. A recent publication in The Lancet Oncology by the International Agency for Research on Cancer (IARC) concludes that there is limited evidence that polychlorinated biphenyls (PCBs) cause breast cancer in humans. As described below, the WTC Program Administrator (Administrator) has found that PCBs were present in WTC dust in the New York City disaster area and, accordingly, the Program will now certify breast cancer in eligible WTC responders and survivors who were exposed to either shiftwork/nighttime sleep disruption or PCBs as a result of the 9/11 attacks.

Proposed Formaldehyde Emissions Standards for Composite Wood Products EPA is proposing new requirements under the Formaldehyde Standards for Composite Wood Products Act, or Title VI of the Toxic Substances Control Act (TSCA). These proposed requirements are designed to implement the statutory formaldehyde emission standards for hardwood plywood, medium-density fiberboard, and particle board sold, supplied, offered for sale, or manufactured (including imported) in the United States. As directed by the statute, this proposal includes provisions relating to, among other things, laminated products, products made with no-added formaldehyde resins or ultra low-emitting formaldehyde resins, testing requirements, product labeling, chain of custody documentation and other recordkeeping requirements, enforcement, and product inventory sell-through provisions, including a product stockpiling prohibition. The composite wood product formaldehyde emission standards contained in TSCA Title VI are identical to the emission standards currently in place in California. This regulatory proposal implements these emissions standards and is designed to ensure compliance with the TSCA Title VI formaldehyde emission standards while aligning, where practical, with the regulatory requirements in California.

Proposed Formaldehyde; Third-Party Certification Framework for the Formaldehyde Standards for Composite Wood Products The Formaldehyde Standards for Composite Wood Products Act (Title VI of the Toxic Substances Control Act (TSCA)) establishes formaldehyde emission standards for hardwood plywood, particle board, and medium-density fiberboard (composite wood products) and directs EPA to promulgate implementing regulations by January 1, 2013. Pursuant to the requirements of TSCA Title VI, EPA is proposing a framework for a TSCA Title VI Third-Party Certification Program for composite wood products. Under the framework, third-party certifiers (TPCs) would be accredited by EPA-recognized accreditation bodies (ABs) so that TPCs may certify composite wood product panel producers under TSCA Title VI. This proposed rule identifies the roles and responsibilities of the TPCs and ABs involved, as well as the criteria for participation in the TSCA Title VI Third-Party Certification Program. The Agency is proposing the TSCA Title VI Third-Party Certification Program framework prior to the rest of the TSCA Title VI implementing regulations in order to allow interested parties an opportunity to comment and to begin identifying the business practices and infrastructure that may need to be modified or developed in order to effectively participate in the program.

Proposed Guar Hydroxypropyltrimethylammonium Chloride; Exemption From the Requirement of a Tolerance This regulation establishes an exemption from the requirement of a tolerance for residues of guar hydroxypropyltrimethylammonium chloride (CAS Reg. No. 71329-50-5) when used as an inert ingredient (thickener/drift reduction agent) in pesticide formulations applied to growing crops. SciReg. Inc., on behalf of Rhodia Inc., submitted a petition to EPA under the Federal Food, Drug, and Cosmetic Act (FFDCA), requesting establishment of an exemption from the requirement of a tolerance. This regulation eliminates the need to establish a maximum permissible level for residues of guar hydroxypropyltrimethylammonium chloride.

Proposed Control of Air Pollution From Motor Vehicles: Tier 3 Motor Vehicle Emission and Fuel Standards This action would establish more stringent vehicle emissions standards and reduce the sulfur content of gasoline beginning in 2017, as part of a systems approach to addressing the impacts of motor vehicles and fuels on air quality and public health. The proposed gasoline sulfur standard would make emission control systems more effective for both existing and new vehicles, and would enable more stringent vehicle emissions standards. The proposed vehicle standards would reduce both tailpipe and evaporative emissions from passenger cars, light-duty trucks, medium-duty passenger vehicles, and some heavy-duty vehicles. This would result in significant reductions in pollutants such as ozone, particulate matter, and air toxics across the country and help state and local agencies in their efforts to attain and maintain health-based National Ambient Air Quality Standards. Motor vehicles are an important source of exposure to air pollution both regionally and near roads. These proposed vehicle standards are intended to harmonize with California's Low Emission Vehicle program, thus creating a federal vehicle emissions program that would allow automakers to sell the same vehicles in all 50 states. The proposed vehicle standards would be implemented over the same timeframe as the greenhouse gas/fuel efficiency standards for light-duty vehicles, as part of a comprehensive approach toward regulating emissions from motor vehicles.

Food and Drug Administration (FDA)

Notice Type Title Summary of Notice NTP Information Cited CASRN
Proposed Safety and Effectiveness of Consumer Antiseptics; Topical Antimicrobial Drug Products for Over-the-Counter Human Use; Proposed Amendment of the Tentative Final Monograph; Reopening of Administrative Record. The Food and Drug Administration (FDA) is issuing this proposed rule to amend the 1994 tentative final monograph or proposed rule (the 1994 TFM) for over-the-counter (OTC) antiseptic drug products. In this proposed rule, we are proposing to establish conditions under which OTC consumer antiseptic products intended for use with water (referred to throughout as consumer antiseptic washes) are generally recognized as safe and effective. In the 1994 TFM, certain antiseptic active ingredients were proposed as being safe for antiseptic handwash use by consumers based on safety data evaluated by FDA as part of our ongoing review of OTC antiseptic drug products. However, in light of more recent scientific developments and changes in the use patterns of these products we are now proposing that additional safety data are necessary to support the safety of antiseptic active ingredients for this use. We also are proposing that all consumer antiseptic wash active ingredients have data that demonstrate a clinical benefit from the use of these consumer antiseptic wash products compared to nonantibacterial soap and water.

Occupational Safety and Health Administration (OSHA)

Notice Type Title Summary of Notice NTP Information Cited CASRN
Proposed Occupational Exposure to Respirable Crystalline Silica The Occupational Safety and Health Administration (OSHA) proposes to amend its existing standards for occupational exposure to respirable crystalline silica. The basis for issuance of this proposal is a preliminary determination by the Assistant Secretary of Labor for Occupational Safety and Health that employees exposed to respirable crystalline silica face a significant risk to their health at the current permissible exposure limits and that promulgating these proposed standards will substantially reduce that risk. This document proposes a new permissible exposure limit, calculated as an 8-hour time-weighted average, of 50 micrograms of respirable crystalline silica per cubic meter of air (50 μg/m3). OSHA also proposes other ancillary provisions for employee protection such as preferred methods for controlling exposure, respiratory protection, medical surveillance, hazard communication, and recordkeeping. OSHA is proposing two separate regulatory texts—one for general industry and maritime, and the other for construction—in order to tailor requirements to the circumstances found in these sectors.
