OSHA requirements are set by statute, standards and regulations. Our interpretation letters explain these requirements and how they apply to particular circumstances, but they cannot create additional employer obligations. This letter constitutes OSHA's interpretation of the requirements discussed. Note that our enforcement guidance may be affected by changes to OSHA rules. Also, from time to time we update our guidance in response to new information. To keep apprised of such developments, you can consult OSHA's website at https://www.osha.gov.

The Honorable Eni F.H. Faleomavaega
U.S. House of Representatives
Washington, D.C. 20515

Dear Congressman Faleomavaega:

This is in response to your request to the Occupational Safety and Health Administration (OSHA) for a list of all OSHA-regulated air contaminants.

Enclosed is a copy of 29 CFR 1910.1000, Air Contaminants Rule as published in the Federal Register (FR 35338) on June 30, 1993. This regulation establishes the permissible exposure limits (PEL) for substances that are not regulated under a substance specific standard, such as the general industry lead standard, 29 CFR 1910.1025. Also, a list of the substance specific standards is enclosed that shows the specific air contaminant standards included in Part 1910, Subpart Z.

We hope this document is useful to you as a needed resource for concerns about employee exposure to harmful substances. We appreciate the opportunity to be of assistance to you. Should you have any further questions, please feel free to contact Mr. Lewis Ligon of OSHA's Office of Health Compliance Assistance at (202) 219-8036.


Joseph A. Dear
Assistant Secretary

John Miles, Berrien Zettler, and I met with Cong. F and staff from Sen. Inouye's office about Star Kist. He praised OSHA's efforts and said he would write the Secretary to thank him for protecting American Samoa's workers. He also asked that we send him a list of all OSHA-regulated air contaminants, with the thought that Star Kist is violating the law by letting rooting fish fill the air with pollution. Finally, he asked that we keep him apprised of our follow-up to ensure that the company abates.
