Industry Signals Data Law Attack On EPA Air Rules Over Formaldehyde Risks

摘要

Chemical manufacturers are signaling they may bring a data quality challenge to Epa's pending air toxics rules for the oil and natural gas drilling sector because the agency relied on safe exposure limits in its 1991 cancer assessment of formaldehyde, which the industry says is outdated and overly stringent. The warning, contained in Nov. 30 comments to the agency from the American Chemistry Council (ACC), high lights the struggle Epa faces to craft rules regulating formaldehyde since a National Academy of Sciences (NAS) panel earlier this year strongly criticized the agency's 2010 draft risk assessment of the substance that set conservative new exposure limits and had, for the first time, deemed the substance to be a leukemogen.
