Communication Contents: -From E.C. Jenik, Chairman, Utility Location and Coordination Council: At the ULCC Executive Committee meeting on September 12, 1982, the NTSB Safety Recommendation P-82-10 was unanimously endorsed. The Committee further directed the chairman to notify each of the APWA Local Chapter Presidents of this decision and to encourage the entire membership to support and promote this recommendation. An article will also be prepared for our official magazine, APWA Reporter, highlighting this Safety Recommendation and the benefits to be derived through participation in the "One Call" concept. As you know, ULCC is committed to promoting all effective means to minimize potential hazards to excavators, Public Works and utility workers and the general public. I believe this action is one more step toward achieving that goal.
