Imagine receiving a certified letter from the US Environmental Protection Agency (EPA) announcing that it plans to conduct an audit of your company’s facility in two weeks. The audit will focus on your company’s compliance obligations as a chemical manufacturer under the Toxic Substances Control Act (TSCA). Would you be prepared or are you unsure of what TSCA is and whether it applies to you? This article explains how TSCA applies to biobased chemicals and how nomenclature and chemical identity can impact commercialization.
On May 29, 2015, the U.S. Department of Labor’s Occupational Safety and Health Administration (OSHA) published the “Interim Enforcement Guidance for Hazard Communication 2012 (HCS 2012) June 1, 2015 Effective Date” (Interim Guidance). This supplements the February 9, 2015, “Enforcement Guidance for the Hazard Communication Standard’s (HCS) June 1, 2015 Effective Date” (Enforcement Guidance). The Interim Guidance clarifies specific points to manufacturers, importers, and distributors on OSHA’s HCS enforcement strategy.
The Organization for Economic Cooperation and Development (OECD) issued a June 9, 2015, press release entitled "OECD chemical studies show way forward for nanomaterial safety."
On June 5, 2015, the U.S. Environmental Protection Agency (EPA) promulgated through a direct final rule significant new use rules (SNUR) for 22 chemical substances that were the subject of premanufacture notices (PMN), including graphene nanoplatelets having a predominant thickness of 1-10 layers with lateral dimension predominantly less than 2 microns (PMN Number P-14-763).
On May 19, 2015, the U.S. Environmental Protection Agency (EPA) announced that it issued a conditional registration for a nanosilver-containing antimicrobial pesticide product named "NSPW-L30SS," or "Nanosilva."
In the second installment of this series, I wrote about how the Toxic Substances Control Act (TSCA) regulates products across a manufacturing process, from feedstock to product. In this last installment, I present options for updating TSCA and the related implementing regulations to put novel, biobased chemistry on an even footing with incumbent products and processes that were grandfathered in as part of the original TSCA Inventory. The key is to find a way to level the field without compromising the U. S. Environmental Protection Agency’s (EPA) mission and authority to protect human health and the environment.
On April 28, 2015, the Senate Committee on Environment and Public Works held a hearing to consider the Frank R. Lautenberg Chemical Safety for the 21st Century Act (S. 697). Since then, S. 697 has gained additional backing from both Republicans and Democrats. These events are important because they demonstrate significant bipartisan support for reform of the Toxic Substances Control Act (TSCA), and suggest TSCA reform actually may be in our future.
Membership in the Sustainable Nanotechnology Organization (SNO) offers a number of benefits to members of the nano community. SNO's purpose is to provide a professional society forum to advance knowledge in all aspects of sustainable nanotechnology, including both applications and implications.
In the first installment of this series, I wrote about how the Toxic Substances Control Act (TSCA) regulates products. In this article, we will look across a manufacturing process. TSCA applies to chemical substances that are used for purposes other than food, food additives, animal feed, cosmetics, drugs, tobacco and tobacco products, pesticides, munitions, and nuclear source materials. Biobased chemicals, that is, chemicals made from lignocellulose or other biomass, are finding markets in food and cosmetic markets, but much of the recent innovation focuses on biobased fuels and commodity chemicals. For these final products, TSCA applies. Chemical products must be listed on the TSCA Inventory of Chemical Substances (the Inventory) or be eligible for an exemption. If the product is not listed on the Inventory, the manufacturer must file a premanufacture notification 90 days before manufacturing (or importing) that substance or qualify for an appropriate exemption.
On April 27, 2015, the National Institute for Occupational Safety and Health (NIOSH) announced publication of "Carbon Nanotube and Nanofiber Exposure Assessments: An Analysis of 14 Site Visits" in Annals of Occupational Hygiene. The paper is the second report from NIOSH's Industrywide Study. According to NIOSH, the findings illustrate which tasks have the highest exposures, trends in exposure, nature and character of materials involved, effectiveness of controls when used, and continued refinement of the methods used to evaluate exposure of this high-priority class of nanomaterials.
