Safety Recommendation History
From: NTSB
To: UGI Corporation
Date: 8/7/2001
Response: The Safety Board is pleased to learn that UGI has worked with other regional utilities and transmission companies, both gas and oil, to develop common action and communication protocols, and that these have been incorporated into a pamphlet mailed to all contractors/excavators and local governments on file at the Pennsylvania One-Call, Inc., Center. UGI also sent One-Call pamphlets to contractors/excavators and local governments within its service territory and developed "tip" cards carrying essential substructure damage prevention/emergency action steps for excavators to follow. These cards are made available to UGI personnel to hand to excavators at construction sites and pre-construction meetings. The Safety Board also understands that, to further its substructure damage initiatives, UGI is in the process of joining the national Common Ground Alliance, and that the company continues to provide emergency response training programs for local fire departments throughout its service territory. Because UGI has taken the requested action, Safety Recommendation P-96-6 is classified "Closed--Acceptable Action."
