Following a six-month investigation, the Alaska Dept. of Labor and Workforce Development has issued a total of 24 citations, with associated fines of $882,000, to three companies on a power-plant expansion project in Anchorage. The inquiry found that a pressure-relief valve had been removed from a steam piping system, which was placed into service without any other safeguards present. Two days later, an event occurred that caused sudden high pressures and violent shaking of the system, threatening life safety and damage to equipment, the agency concluded.

The incident occurred during start-up and commissioning of Anchorage Municipal Light and Power’s 120-MW George M. Sullivan plant 2A after 28 months of construction to replace six aging simple-cycle, natural-gas turbines with a combined-cycle configuration. The utility asked Universal Energy LLC, the start-up operator, to shut down the system to prevent a catastrophic failure, but the operator delayed shut-down, causing ML&P to evacuate its employees until the area could be deemed safe, the investigation found.

在3月下旬的调查结束时，劳工部发出了13次故意引用，相关罚款为182,000美元。建筑经理Price Gregory International Inc.收到了五次故意引用，罚款为280,000美元，工程，采购和建筑承包商的Quanta Power Generation Inc.收到了六项故意引用，罚款为420,000美元。当发现不安全的条件时，市政的光线和电源没有引用其迅速撤离该地点。

On April 5, Universal Energy announced that it has reached a settlement with AKOSH, the state’s safety agency, “with a significant reduction in citations.” The company emphasized, “there were no injuries nor equipment damage” during the incident. Price Gregory and Quanta Power have 15 working days to request an informal conference or a notice of contest, says Greg Cashen, deputy commissioner of the Dept. of Labor.
