Washington, DC — National workplace exposure standards for thousands of chemicals have not been promulgated and hundreds of existing standards are much weaker than needed to protect workers. Yet, the Obama administration is pursuing policies that will slow the glacial pace of Occupational Health & Safety Administration (OSHA) exposure rulemaking even further, according to Public Employees for Environmental Responsibility (PEER).
Compared to safety regulation, OSHA has lagged badly in health regulation. Today, OSHA’s health rulemaking docket is so far behind that it is overwhelmed. Save for a handful of substances, the vast majority of Permissible Exposure Limits (PELs) have not been updated since 1968. In the late 1980s, OSHA tried to tighten about 420 PELs without using the modern risk assessment methods the Supreme Court had already required in a 1980 decision, and these limits were struck down en masse in 1992.
During the ensuing 18 years, OSHA has made scant progress on the health front:
- OSHA has issued no new health standards since 1998, save for one ordered by a court;
- In that one case, the resultant chromium standard was the weakest toxic-substance standard ever issued by a federal agency, allowing approximately 80% of all the industrial users of chromium to weaken the few controls they already had put in place. This new limit consigns roughly an additional 4% of exposed employees to lung cancer; and
- Existing standards for hundreds of known toxics are woefully inadequate. For example, rulemakings to update inadequate standards for silica and beryllium (both of which cause fatal lung disease) have been stalled since the 1980s. Another example is diacetyl (known since 2001 to cause bronchiolitis obliterans, or “popcorn lung disease” in workers exposed to this artificial butter flavoring). OSHA fruitlessly promised action on diacetyl more than 5 years ago.
Health standard-setting is hopelessly backlogged with little chance of catching up,” stated PEER Policy Director Erica Rosenberg, pointing out that workplace exposures are now the eighth leading cause of death in the U.S., resulting in more than 40,000 premature deaths per year or roughly ten times the death toll from industrial accidents. “Unless OSHA makes its health mission a top priority, American workers will remain unprotected from a growing array of toxic substances on the job.”
Despite this huge backlog, the Obama administration is adding extra review processes that will further delay every long-overdue health regulation currently in the pipeline. In June, OSHA announced it would convene two special peer review panels per standard to review both the science and the economics before proposed standards appear in the Federal Register.
OSHA is unusual among federal agencies in that its regulatory proposals are subject to a public hearing in front of a judge in which anyone can challenge the scientific or other rationale for proposals. This adjudicated process is a more daunting and rigorous form of peer review than what occurs in academia.
“OSHA has let self-proclaimed ‘experts’ on the outside run roughshod over its own career scientists for far too long,” said Dr. Adam Finkel, a risk assessment expert in academia, a former OSHA Director of Health Standards Programs and a member of the PEER Board of Directors, noting the agenda for a March 4th public hearing (called “OSHA Listens”) includes suggestions for ideas to address “the length and difficulty of the current OSHA rulemaking process.” “Without cutting any corners in its use of the best scientific and economic information, OSHA can put its life-saving regulatory proposals before the public.”
In its testimony next week, among other recommendations, PEER is calling upon new Assistant Secretary David Michaels to cancel the optional peer reviews for the silica, beryllium, diacetyl, and other standards.
