Oregon State Plan; Approval of Plan Supplements; Changes in Level of Federal Enforcement, Including Umatilla Indian Reservation

This document gives notice of the approval of a State- initiated plan change and assumption of Federal OSHA enforcement authority in the State of Oregon over all private sector establishments, including tribal and Indian-owned enterprises, on all Indian and non-Indian lands within the currently established boundary of the Umatilla Indian Reservation, and on lands outside the reservation that are held in trust by the Federal government for the Confederated Tribes of the Umatilla (Umatilla Tribes). Oregon OSHA will retain its enforcement jurisdiction over public sector (State and local government) employees working on these lands. This document also gives notice of the approval of several other changes in the level of Federal enforcement in the State of Oregon. A 1991 addendum to Oregon's operational status agreement contained four changes to the circumstances under which Federal enforcement jurisdiction may be exercised within the State, including situations where Oregon is refused entry to an establishment. In addition, Oregon has assumed responsibility for worker protection at Superfund sites (except on military bases) and with regard to private contractors working on U.S. Army Corps of Engineers dam construction projects, as reflected in a 1992 Memorandum of Understanding between Federal OSHA and the State of Oregon. OSHA is hereby amending its regulation on approved plans to reflect these changes to the level of Federal enforcement authority in Oregon, and correcting a few typographical errors.
