What Are the Administrative Requirements for This Action?

For information regarding other administrative requirements for this action, please see the direct final rule action that is located in the Rules and Regulations section of this Federal Register .

Regulatory Flexibility Act (RFA), as Amended by the Small Business Regulatory Enforcement Fairness Act of 1996 (SBREFA), 5 U.S.C. 601 et seq.

The RFA generally requires an agency to prepare a regulatory flexibility analysis of any rule subject to notice and comment rulemaking requirements under the Administrative Procedure Act or any other statute unless the agency certifies that the rule will not have a significant economic impact on a substantial number of small entities. Small entities include small businesses, small organizations, and small governmental jurisdictions.

We have determined that it is not necessary to prepare a regulatory flexibility analysis in connection with this proposed rule. The purpose of the proposed amendments is to clarify the rule and, therefore, will not impose new requirements or compliance costs on industry. Therefore, I certify that this action will not have a significant economic impact on a substantial number of small entities.

Although the proposed amendments will not have a significant impact on a substantial number of small entities, we worked with the portland cement industry, including small entities, throughout the rulemaking process. Meetings were held on a regular basis with industry representatives to discuss the development of the proposed amendments in connection with the settlement agreement, exchange information, and solicit comments on the proposed requirements.
