The Oregon plan provides for adoption of State standards which are at least as effective as comparable to Federal standards promulgated under section 6 of the Acct. Section 1953.20 provides that where 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 shall be required. Having reviewed the State''s submission in comparison with Federal standards, OSHA has determined that the State''s standards amendments are identical or substantially identical to the comparable Federal standards and therefore approves these amendments. A copy of the standards supplement, along with the approved plan, may be inspected and copied during normal business hours at the following locations: Office of the Regional Administrator, OSHA, 1111 Third Avenue, Suite 715, Seattle, WA 98101-3212; Oregon OSH Div, Dept. of Insurance and Finance, 21 Labor and Industries Bldg, room 160, 350 Winter St., NE,. Salem, Oregon 97310; and the Office of State Programs, OSHA, Room N- 3700, 200 Constitution Ave., NW., Washington, DC 20210. The standard amendments were adopted in accordance with the procedural requirements of State law and further public participation would be repetitious. This decision is effective November 4, 1992.
