Post-Hearing Comments on OSHA's Proposed Hexavalent Chromium Rule

Read Public Citizen's complete comments on OSHA's proposed hexavalent chromium rule (in pdf)

April 20, 2005

OSHA’s October 2004 Proposed Rule on the lung carcinogen hexavalent chromium and testimony at the February 2005 hearing make a clear case that a PEL of 0.25 ug/m3 (lower than OSHA’s proposed PEL of 1 ug/m3) is justified on health grounds, and is economically and technologically feasible.   Electroplating and welding are the only significant industries for whom economic feasibility is even remotely an issue, and almost half these workers are already compliant with a PEL of 0.25 ug/m3.  OSHA has questioned the technological feasibility of a PEL lower than 1 ug/m3 in hard chrome electroplating and certain welding operations.  However, in these industries, either large fractions of workers are already under 0.25 ug/m3 or OSHA has failed to justify why a lower PEL is technologically infeasible.

Public Citizen’s legal analysis demonstrates that a requirement for respiratory protection for some workers in a minority of sub-industries is not a justification for failing to lower the PEL for all workers, as long as there remains residual significant health risk. In addition, exempting the construction and maritime sectors from monitoring for hexavalent chromium is a misplaced effort to reduce the compliance burden for employers; instead it transfers a major health burden to American workers. With this proceeding entering its 13th year, and with the hearing and the Proposed Rule having exposed the industry counter-arguments as essentially groundless, the time has come to adopt the 0.25 ug/m3 PEL that workers require and that the science supports.

Public Citizen, Inc. and Public Citizen Foundation


Together, two separate corporate entities called Public Citizen, Inc. and Public Citizen Foundation, Inc., form Public Citizen. Both entities are part of the same overall organization, and this Web site refers to the two organizations collectively as Public Citizen.

Although the work of the two components overlaps, some activities are done by one component and not the other. The primary distinction is with respect to lobbying activity. Public Citizen, Inc., an IRS § 501(c)(4) entity, lobbies Congress to advance Public Citizen’s mission of protecting public health and safety, advancing government transparency, and urging corporate accountability. Public Citizen Foundation, however, is an IRS § 501(c)(3) organization. Accordingly, its ability to engage in lobbying is limited by federal law, but it may receive donations that are tax-deductible by the contributor. Public Citizen Inc. does most of the lobbying activity discussed on the Public Citizen Web site. Public Citizen Foundation performs most of the litigation and education activities discussed on the Web site.

You may make a contribution to Public Citizen, Inc., Public Citizen Foundation, or both. Contributions to both organizations are used to support our public interest work. However, each Public Citizen component will use only the funds contributed directly to it to carry out the activities it conducts as part of Public Citizen’s mission. Only gifts to the Foundation are tax-deductible. Individuals who want to join Public Citizen should make a contribution to Public Citizen, Inc., which will not be tax deductible.
