BERYLLIUM PROPOSAL
OSHA will issue a proposed rule regulating occupational exposure to beryllium before the end of the year. It published a request for information (RFI) in November 2002 to solicit data on occupational exposure to beryllium, including current expo- sures to beryllium, the relationship between beryllium exposure and the development of adverse health effects, exposure assessment and monitoring methods, exposure- control methods and medical surveillance. OSHA completed a review panel report on the proposal in January 2008 and a scientific peer review of its draft risk assessment in November 2010.
Ozone Regulation Tis summer EPA’s Advisory
Panel and staff recommended to the EPA Administrator that the national air standards for ozone be lowered to 60-70 parts per billion (ppb) from the current 75-ppb standard, which was set in 2008. Te agency cites scientific data and exposure information that “provide strong support” for revising the health-based national ambient air quality standard for ozone of 75 ppb. Te EPA Office of Air Quality
Planning and Standards, which pre- pared the assessment, said a revised
standard set within that range “could reasonably be judged to provide an appropriate degree of public health protection, including for at-risk populations and life stages.” Te regulation could become the most costly in U.S. history if the new standard is implemented. In 2010, EPA estimated the annual compli- ance costs for a 60-ppb standard would be $90 billion in 2020. Te National Association of Manufac- turers (NAM) released a report in July that estimated a revised ozone standard of 60 ppb could cost the
U.S. economy up to $270 billion per year and result in the closure of one-third of the nation’s coal-fired power plants. Te lower standard will require large reductions in NOx and volatile organic compound (VOC) emissions from power plants, manu- facturing facilities and mobile sources such as cars, trucks and off-road vehicles. Requiring a reduction to 60 ppb would leave nearly all of the U.S. in a so-called “nonattainment zone.” Metalcasting facilities of all sizes in nonattainment areas would not be able to make investments and expand operations without other businesses reducing their emissions or, worse yet, shuttering their operations. EPA has until December 1 to decide whether to keep or change current national air quality standards for ozone. Presi- dent Obama delayed EPA’s previous attempt to promulgate a lower ozone air quality standard in 2011. A final rule is expected to be made by Octo- ber 2015.
