True to her word, yesterday U.S. Environmental Protection Agency (EPA) Administrator Lisa P. Jackson announced action plans on phthalates, long-chain perfluorinated chemicals (PFC), polybrominated diphenyl ethers (PBDE) in products, and short-chain chlorinated paraffins (SCCP).  This EPA initiative announces actions that are almost breathtaking in scope, and its development and implementation of the action plan items will set a number of new precedents — and possibly shape future...

In a December 16, 2009, letter, three members of the Wisconsin Assembly requested that a Legislative Council study be conducted on the feasibility of creating a nanotechnology registry and the development of subsequent legislation to monitor the use, manufacture, and disposal of nanomaterials in Wisconsin. The letter, signed by State Representatives Terese Berceau (D), Chuck Benedict (D), and Penny Bernard Schaber (D), notes that entities manufacturing or using nanomaterials in Wisconsin are...

The Occupational Safety and Health Administration (OSHA) proposed on Sept. 30, 2009, to align the Hazard Communication Standard (HCS) with provisions of the United Nations Globally Harmonized System of Classification and Labeling of Chemicals (GHS). The HCS requires chemical manufacturers and importers to evaluate chemical hazards and provide information to subsequent users. The standard now requires employers to establish a hazard communication program for employees who are exposed to chemicals...

Last month, Bayer Material Science (BMS) announced that it derived an occupational exposure limit (OEL) of 0.05 milligrams per cubic meter (mg/m3) for Baytubes, BMS multi-wall carbon nanotubes. According to BMS, “[t]he latest results of sub-chronic inhalation studies support the conclusion that Baytubes act like poorly soluble particles.” BMS derived the OEL based on previous single and recent repeated inhalation studies. BMS states: “All relevant information...

Publicly traded companies are required, under Securities and Exchange Commission (SEC) regulations, to disclose known and contingent material liabilities to ensure investors have reliable information on which to base their investment decisions.

The National Institute for Occupational Safety and Health (NIOSH) announced that it will hold a conference entitled “Nanomaterials and Worker Health:  Medical Surveillance, Exposure Registries, and Epidemiologic Research,” on July 21-23, 2010, at the Keystone Resort and Conference Center in Keystone, Colorado. According to NIOSH, the goal of the conference is to identify gaps in information and address questions focusing on occupational health surveillance, exposure registries, and...

On April 15, 2009, the U.S. Environmental Protection Agency (EPA) issued its final list of chemicals in the first group of substances that will be screened under the Endocrine Disruptor Screening Program (EDSP). Development of this list caps a long, thoughtful, and arduous administrative process that spans over a decade. This “Washington Watch” column briefly reviews the development of the program, with emphasis on key elements of the current EDSP. The discussion also highlights the...

Approximately 5.4 million cubic yards, or 1.1 billion gallons, of coal ash from the Tennessee Valley Authority (TVA) plant near Knoxville, Tenn., in December 2008 flooded some 300 acres of land, damaging property, polluting waterways, and killing fish. TVA will likely spend more than $500 million and perhaps as much as $1 billion dollars on the cleanup, says the U.S. Environmental Protection Agency (EPA). The TVA debacle was EPA’s wake-up call for potential hazards presented...
