HSC Harsco Corporation

Global industrial solutions company Harsco Corporation (NYSE:HSC) announced today the expansion of its work on a major brownfield energy plant in the U.S. regarded as one of the cleanest coal-burning plants ever built in the United States. By the time of project completion in early 2012, Harsco's role is expected to have produced revenues of approximately $25 million in sales and services, making it one of Harsco Infrastructure's key North American projects for 2011-2012 and a prime example of the group's capabilities for supporting major industrial and civil works projects worldwide.

Harsco is providing scaffold access services for the completion of Dominion Virginia Power's 585-megawatt Virginia City Hybrid Energy Center (VCHEC), an all-new electric power generating facility being built in southwestern Virginia. Harsco was selected for the project by The Shaw Group Inc., the project's engineering, procurement and constructor, to perform an independent analysis of the project's optimum scaffold requirements and associated labor productivity. Harsco's role has expanded to include scaffold project management over a peak work force on site of 375 certified scaffold erectors, with over 2,000 access platforms erected.

Harsco's ability to manage complex access labor projects along with the implementation of Harsco's proprietary Scaffold Tracker Project Professional® program have both benefited the project's productivity goals. "Harsco Infrastructure's partnership with Shaw has contributed to productivity and cost savings," said Robert Ball, Shaw's project manager. "Harsco's commitment to safety has added to a safe work environment and culture on site," he continued. "Our employees use their scaffolds daily." The scope and effectiveness of Harsco's role is expected to lead to future bidding opportunities on additional energy and infrastructure projects across the globe.

Harsco Corporation is a diversified global solutions company serving industries that are fundamental to worldwide infrastructure development and economic growth, including steel and metals, construction, railways and energy. Harsco's common stock is a component of the S&P Mid-Cap 400 Index and the Russell 1000 Index. Additional information can be found at www.harsco.com.
