On February 16, 2021, OSHA published a Notice of Proposed Rulemaking (NPRM) to modify the Hazard Communication Standard (HCS) to align with the United Nations' Globally Harmonized System of Classification and Labelling of Chemicals (GHS) Revision 7, to address specific issues that have arisen since OSHA last updated the HCS in 2012, and to provide better alignment with other U.S. agencies and international trading partners, without lowering the overall protections of the standard.

OSHA received comments concerning the proposed rule during the comment period, which ended May 19, 2021. Commenters shared information on a variety of topics including proposed definitions of “release for shipment” and “immediate outer container,” changes to paragraph (d)(1) “normal conditions of use,” and clarification of compliance dates. OSHA received two requests for an informal public hearing (Document ID 0276 and 0294).

Informal Public Hearing—Purpose, Rules and Procedures

OSHA invites interested persons to participate in this rulemaking by providing oral testimony and documentary evidence at the informal public hearing. OSHA also welcomes presentation of data and documentary evidence that will provide the agency with the best available evidence to use in developing the final rule.

Pursuant to 29 CFR 1911.15(a) and 5 U.S.C. 553(c), members of the public have an opportunity at the informal public hearing to provide oral testimony and evidence on issues raised by the proposal. An administrative law judge (ALJ) will preside over the hearing and will resolve any procedural matters relating to the hearing.

OSHA's regulation governing public hearings (29 CFR 1911.15) establishes the purpose and procedures of informal public hearings. Although the presiding officer of the hearing is an ALJ and questioning of witnesses is allowed on crucial issues, the proceeding is largely informal and essentially legislative in purpose. Therefore, the hearing provides interested persons with an opportunity to make oral presentations in the absence of rigid procedures that could impede or protract the rulemaking process. The hearing is not an adjudicative proceeding subject to the Federal Rules of Evidence. Instead, it is an informal administrative proceeding convened for the purpose of gathering and clarifying information. Accordingly, questions of relevance, procedure, and participation generally will be resolved in favor of developing a clear, accurate, and complete record.

Conduct of the hearing will conform to 29 CFR 1911.15. In addition, pursuant to 29 CFR 1911.4, the Acting Assistant Secretary may, on reasonable notice, issue additional or alternative procedures to expedite the proceedings, to provide greater procedural protections to interested persons, or to further any other good cause consistent with applicable law. Although the ALJ presiding over the hearing makes no decision or recommendation on the merits of the proposal, the ALJ has the responsibility and authority necessary to ensure that the hearing progresses at a reasonable pace and in an orderly manner. To ensure a full and fair hearing, the ALJ has the power to regulate the course of the proceedings; dispose of procedural requests, objections, and comparable matters; confine presentations to matters pertinent to the issues the proposed rule raises; use appropriate means to regulate the conduct of persons present at the hearing; question witnesses and permit others to do so; limit the time for such questioning; and leave the record open for a reasonable time after the hearing for the submission of additional data, evidence, comments, and arguments from those who participated in the hearing (29 CFR 1911.16).

At the close of the hearing, there will be a post-hearing comment period for interested persons who filed a timely notice of intention to appear at the hearing, during which those persons may submit final briefs, arguments, summations, and additional data and information to OSHA.

Notice of Intention To Appear at the Hearing

Interested persons who intend to participate in and provide oral testimony or documentary evidence at the hearing must file a written notice of intention to appear prior to the hearing. To testify or question witnesses at the hearing, interested persons must electronically submit their notice by June 18, 2021. The notice must provide the following information:

Name, address, email address, and telephone number of each individual who will give oral testimony;

Name of the establishment or organization each individual represents, if any;

Occupational title and position of each individual testifying;

Approximate amount of time required for each individual's testimony;

A brief statement of the position each individual will take with respect to the issues raised by the proposed rule; and

A brief summary of documentary evidence each individual intends to present. Individuals who request more than 10 minutes to present their oral testimony at the hearing or who will submit documentary evidence at the hearing must submit the full text of their testimony and all documentary evidence no later than August 21, 2021.

The agency will review each submission and determine if the information it contains warrants the amount of time the individual requested for the presentation. If OSHA believes the requested time is excessive, the agency will allocate an appropriate amount of time for the presentation. The agency also may limit to 10 minutes the presentation of any participant who fails to comply substantially with these procedural requirements, and may request that the participant return for questioning at a later time. Before the hearing, OSHA will notify participants of the time the agency will allow for their presentation and, if less than requested, the reasons for its decision. In addition, before the hearing, OSHA will provide the hearing procedures and hearing schedule to each participant who filed a notice of intention to appear. OSHA emphasizes that the hearing is open to the public; however, only individuals who file a notice of intention to appear may question witnesses and participate fully at the hearing. If time permits, and at the discretion of the ALJ, an individual who did not file a notice of intention to appear may be allowed to testify at the hearing, but for no more than 10 minutes.

Certification of the Hearing Record and Agency Final Determination

Following the close of the hearing and the post-hearing comment periods, the ALJ will certify the record to the Assistant Secretary of Labor for Occupational Safety and Health. The Start Printed Page 27340record will consist of all of the written comments, oral testimony, and documentary evidence received during the proceeding. The ALJ, however, will not make or recommend any decisions as to the content of the final standard. Following certification of the record, OSHA will review all the evidence received into the record and will issue the final rule based on the record as a whole.
