[Code of Federal Regulations] [Title 29, Volume 9] [Revised as of July 1, 2001] From the U.S. Government Printing Office via GPO Access [CITE: 29CFR1953.20] [Page 128] TITLE 29--LABOR CHAPTER XVII--OCCUPATIONAL SAFETY AND HEALTH ADMINISTRATION, DEPARTMENT OF LABOR--(CONTINUED) PART 1953--CHANGES TO STATE PLANS FOR THE DEVELOPMENT AND ENFORCEMENT OF STATE STANDARDS--Table of Contents Subpart C--Federal Program Change Supplements Sec. 1953.20 Definitions. Source: 39 FR 32905, Sept. 12, 1974, unless otherwise noted. When the Assistant Secretary determines that any alteration in the Federal program could have an adverse impact on the ``at least as effective as'' status of the State program, a program change supplement to a State plan shall be required. Examples of Federal program changes that would require a supplement include promulgation or modification of standards, including emergency temporary standards; revisions in enforcement policies or procedures; and legislative or regulatory changes in the Federal program, including recordkeeping and reporting requirements. A Federal program change that would either not affect or that would result in no diminution of the effectiveness of a State plan, generally would not require action by the States.
