Dear Ms. Camp:

Thank you for your letter to the Occupational Safety and Health Administration (OSHA). Your letter was referred to OSHA's Directorate of Enforcement Programs for a response. You have questions related to OSHA's Hazard Communication standard (HCS), 29 CFR 1910.1200. This letter constitutes OSHA's interpretation only of the requirements discussed and may not be applicable to any question not delineated within your original correspondence. Your paraphrased questions and our responses are below.

Background: You have noted in your letter that 29 CFR 1910.1200(b)(6) states: "This section does not apply to: (i) Any hazardous waste as such term is defined by the Solid Waste Disposal Act, as amended by the Resource Conservation and Recovery Act of 1976, as amended (42 U.S.C. 6901 et seq.), when subject to regulations issued under that Act by the Environmental Protection Agency."

Question 1: Does the HCS apply to universal waste, which is included within the definition of hazardous waste and subject to 40 CFR 273?

Get your hazardous waste labels from Safety Emporium.

Response: No. As noted in the background section, per 29 CFR 1910.1200(b)(6)(i), the HCS does not apply to hazardous wastes regulated by the U.S. Environmental Protection Agency (EPA) under the Resource Conservation and Recovery Act (RCRA). When waste does not meet the definition of "hazardous waste" under the RCRA regulations, it is covered by the HCS if it meets the standard's definition of "hazardous chemical" at 29 CFR 1910.1200(c), and if it does not fall under any of the other HCS exemptions.

RCRA defines "hazardous waste" as "solid waste, or combination of solid wastes, which, because of its quantity, concentration, or physical, chemical, or infectious characteristics may — (A) cause, or significantly contribute to an increase in mortality or an increase in serious irreversible, or incapacitating reversible, illness; or (B) pose a substantial present or potential hazard to human health or the environment when improperly treated, stored, transported, or disposed of, or otherwise managed." 42 U.S.C. § 6903(5). "Solid waste" is defined under RCRA as garbage, refuge, sludge, "and other discarded material." 42 U.S.C. § 6903(27).

hazardous waste management standards under RCRA for certain categories of hazardous waste that are commonly generated by a wide variety of establishments. 40 CFR § 273.81(a). The EPA's universal waste regulations at 40 CFR part 273 apply to four types of universal waste: batteries; pesticides; mercury-containing equipment; and, lamps. 40 CFR §§ 273.1(a), 273.9 (definition of "universal waste"). As these types of universal waste are considered "hazardous waste" under RCRA, they are exempt from the HCS.

HCS. With regard to the "hazardous waste exemption" under paragraph (b)(6)(i), the employer must be able to demonstrate that the material is subject to RCRA regulations. At a minimum, an employer claiming the exemption must be able to produce the appropriate RCRA label and any other RCRA-required identification materials to an inspecting OSHA compliance safety and health officer. Please see OSHA's letter to Ms. Vicki H. Cormier, November 1, 1992, for additional information.

Question 2: Some states regulate additional waste as universal wastes (e.g., oil-based finishes in New Jersey). Is universal waste subject to state regulations only included within the definition of hazardous waste, such that universal waste is not subject to the HCS?

Response: No. The HCS exemption under 29 CFR 1910.1200(b)(i) covers only universal waste that is defined by RCRA regulations as hazardous waste. The exemption does not extend to universal waste subject only to state regulations.

Thank you for your interest in occupational safety and health. We hope you find this information helpful. OSHA's requirements are set by statute, standards, and regulations. Our letters of interpretation do not create new or additional requirements but rather explain these requirements and how they apply to particular circumstances. This letter constitutes OSHA's interpretation of the requirements discussed. From time to time, letters are affected when the Agency updates a standard, a legal decision impacts a standard, or changes in technology affect the interpretation. To assure that you are using the correct information and guidance, please consult OSHA's website at www.osha.gov. If you have any further questions, please feel free to contact the Office of Health Enforcement at (202) 693-2190.

Sincerely,

Patrick J. Kapust, Acting Director
Directorate of Enforcement Programs
