Title 29 › CHAPTER 15 — OCCUPATIONAL SAFETY AND HEALTH › § 667
States may use their own workplace safety rules when there is no federal rule on the issue. If a State wants to take over making and enforcing rules where a federal standard already exists, the State must send in a plan explaining how it will do that. The Secretary will approve the plan if it names the State agency in charge; promises rules and enforcement that are at least as effective as the federal ones and, when they affect items used across state lines, are needed for local reasons and do not unfairly block interstate commerce; ensures inspections without advance notice; shows the agency has legal power, trained staff, and enough money; provides a comparable program for public employees; and requires employers and the State to send reports to the Secretary as requested. If the Secretary rejects a plan or later finds the State is not following it, the State gets notice and a hearing. The State can ask a U.S. court of appeals to review the Secretary’s decision within thirty days. After a plan is approved, the Secretary may keep authority for similar federal standards until he sees the plan working, but not sooner than three years after approval. The Secretary may also let a State keep enforcing its standards temporarily until a final decision on a plan or until two years from December 29, 1970, whichever comes first.
