Narrative
On march 6, 2014, a team fishel employee bored into a sixteen-inch steel high-pressure distribution gas main while installing a fiberoptic line in the intersection of bonneville avenue and grand central parkway in las vegas, nevada. Team fishel had a valid dig ticket and southwest gas corporation's contract line locator had located the line. As part of the line locate process, team fishel was informed that a high-pressure standby would be required during the boring operation. Team fishel failed to meet with the southwest gas corporation representative as it had requested (nrs 455.110(b)(1), see also nac 455.145(1)(b)(3)); failed to expose the facility before commencing boring operations (nrs 455.137(1) & nac 455.150(2)); and failed to notify southwest gas corporation to request additional information when they realized that they could not expose the facility (nrs 455.137(3); nac 455.150(3)). No death or injury resulted from the incident. Although the incident initially did not meet PHMSA/DOT notification criteria, on march 21, 2014, southwest gas corporation estimated the costs associated with the incident would likely meet the criteria, and immediately notified the national response center. Supplemental: subsequent investigation determined that the 16-inch pipeline was not marked correctly.
