Last issue’s installment of the “Washington Watch” column discussed some key issues surrounding nanosilver and noted an ongoing review by the U.S. Environmental Protection Agency (US EPA) Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) Scientific Advisory Panel (SAP). Now that the SAP has issued its much-anticipated report and recommendations, it is worth revisiting the topic of nanosilver pesticides....
Nanoscale materials may figure in Toxic Substances Control Act (TSCA) reform. While not mentioning “nanotechnology,” a bill introduced on April 15, by Sen. Frank Lautenberg (D-NJ) addresses chemicals with “special substantive characteristics.” The bill authorizes the U.S. Environmental Protection Agency (EPA) to evaluate and compel data on new/special uses of existing chemicals “separate from any use of the chemical substance that does not exhibit such special...

Lynn L. Bergeson, “Legal Lookout: Endocrine Disruptors: Test Orders Abound,” Pollution Engineering, June 2010.
In April 2009, EPA identified a final list of 67 chemicals for initial screening under the Endocrine Disruptor Screening Program (EDSP). From October 2009 to April 2010, the agency issued more than 700 test orders. Responding to an EDSP test order can present challenging issues. The agency began implementing this mandate well over a decade ago through the EDSP....
The arsenic Integrated Risk Information System (IRIS) assessment exemplifies the current administration’s unwillingness to walk its own talk on transparency and scientific integrity....
The Toxic Substances Control Act (TSCA) allows the U.S. Environmental Protection Agency (EPA) to keep a list of chemicals that present or may present ‘‘an unreasonable risk of injury to health or the environment.’’ This authority has not been used since TSCA was enacted in 1976. In April, EPA said it intends to propose a rule to add a category of eight phthalates, a category of polybrominated diphenyl ethers, and bisphenol A to such a...
James V. Aidala began working with the Environmental Protection Agency (EPA) as a college intern in the Office of Pesticide Programs; he returned as a policy analyst in the new Office of Pesticides and Toxic Substances (OPTS) after graduate school. From Aidala’s perspective, there was much uncertainty in the early years of Toxic Substances Control Act (TSCA), in part due to challenges with the law’s specificity regarding polychlorinated biphenyls and, later, asbestos and lead, and...
Earlier this year, the U.S. Environmental Protection Agency (EPA) proposed lifting its 1994 administrative stay of Emergency Planning and Community Right-to-Know Act (EPCRA) Section 313 reporting requirements for hydrogen sulfide (H2S). Following is an explanation of why some are concerned, why EPA proposed lifting the stay, and why reporting may be unnecessary in the first place....

Lynn L. Bergeson, “Chemical Pollutants in Water Emerge,” Chemical Processing, April 2010.
Recent advances in contaminant identification methodologies, sampling instrumentation, and analytical chemistry have caused an explosion of knowledge about the presence of previously undetected organic micropollutants. While it doesn’t follow that the mere presence of chemical contaminants results in harm, public health experts, regulators, and others aren’t sitting idly by....
A Recent co-authored paper discussed a number of fundamental changes in U.S. regulation of commercial chemicals that should be considered in revising the Toxic Substances Control Act. As discussed in that paper, while the Environmental Protection Agency under TSCA has broad authority to require testing and reporting of hazard and exposure information on existing chemicals via rulemaking, deploying these authorities have proven cumbersome and inadequate for dealing effectively with the thousands...

Lynn L. Bergeson, “Nanosilver: EPA’s Pesticide Office Considers How Best to Proceed,” Environmental Quality Management, Spring 2010.
In the super-hyped world of nano, nanosilver is the proverbial poster child for all things good and evil, depending upon your perspective. Silver enjoys many commercial applications, and its well recognized antimicrobial properties have been utilized since the beginnings of recorded history. Perhaps because of this success and high visibility, some are taking aim at silver and questioning whether there is too much silver used in industrial applications — and in particular whether there is...
