Under 70a.8 the section is titled "Agency Review of Request for Correction or Amendment to a Record," which covers the agency's process for reviewing requests to correct or amend agency records. See the Part 70 entry on OSHA's site and the original 70a.8 document at https://www.osha.gov/laws-regs/regulations/standardnumber/70a/70a.8.
No, 70a.8 has been redesignated and revised and is no longer the current location for that rule; it was redesignated as part 71.8. For the historical 70a.8 reference see https://www.osha.gov/laws-regs/regulations/standardnumber/70a/70a.8 and check the Part 70 entry for related information.
