This letter constitutes OSHA's interpretation of the requirements discussed. Note that our enforcement guidance may be affected by changes to OSHA rules.

MEMORANDUM FOR: MICHAEL G. CONNORS Regional Administrator THROUGH: LEO CAREY, Director Office of Field Programs FROM: PAT CLARK, Director Directorate of Compliance Programs SUBJECT: Applicability of 1926.800
This is in response to your memo on the above subject, concerning working on rehabilitation of a sewer tunnel that had been constructed in the years between 1926 to 1932.
During this type of underground work an employer would create conditions and hazards associated with underground construction that would be addressed and controlled by the applicable 1926.800 Underground Construction Standards. Therefore, the 1926.800 standards would apply.
If you have any other questions please feel free to contact Frank C. Memmott, Safety Engineer, of my staff on 523-8124.

M/R: The original memo from Connors was apparently misplaced by the OFP. A duplicate memo was received at DCP on 1/2/91.
