OSHA proposed on June 12, 1992, at 57 FR 26002, to issue more protective exposure limits for 376 toxic substances for employees in the construction, maritime and agriculture industries. A comment period and hearings were scheduled. this proposal followed a similar final rule for air contaminants in general industry issued January 19, 1989, at 54 FR 2332. The Air Contaminant proposal for construction, maritime and agriculture is similar in approach to the general industry rule. Accordingly, the court''s decision makes it advisable to extend the comment period and delay the hearings while future actions in response to the decision are implemented. Therefore, OSHA is indefinitely extending the comment period which had been set to close September 25, 1992 for the proposal. OSHA is also postponing the hearings which had been scheduled for October, November and December, 1992. In approximately 6 months OSHA will publish a new closing date for comments and notices of intention to appear, and a new schedule for hearings. The notice to file a notice of intention to appear by September 11, 1992 is also withdrawn. Written comments should be submitted to the OSHA Docket Office, Docket No. H-020A, room N-2634, U. S.D.O.L., 200 Constitution Ave., N.W., Washington, D.C. 20210; Telephone (202)523-7894. For further information contact Mr. James F. Foster, USDOL/OSHA, room N-3647, 200 Constitution Ave., N.W., Washington, D.C. 20210; telephone (202)523-8151.
