This notice announces a 30 day extension of the comment period on the application of the California Division of the United States Testing Company, Inc. for recognition as a Nationally Recognized Testing Laboratory (NRTL) under 29 CFR 1910.7. Interested persons were given until May 22, 1992 in which to comment on the application. OSHA believes a 30 day extension is a sufficient period of time in which to develop comments in view of the fact that the public has already had 60 days in which to submit their comments. The last date for interested parties to submit comments is extended from May 22, 1992 to June 22, 1992.
