Dear Mr. Etchechury:
Gordon Jones called on September 27, 1984, about an interpretation of 1926.652, Table P-2. In the table, the depth of the trench controls the condition to be adhered to. If the trench is 20 feet deep, the 5 to 10 feet and the 10 to 15 feet requirements are negated, therefore, closed sheeting is required.
