Beverly, MA – March 31, 2009 – Envista Corporation, a provider of web-based software for infrastructure project coordination, today announced Columbia Gas of Pennsylvania will implement its map-driven technology for current and future construction projects. Columbia Gas of Pennsylvania, a subsidiary of NiSource, Inc. (NYSE:NI), launched a 20-year natural gas infrastructure replacement program in 2007.

The infrastructure replacement program is an ongoing, long-term endeavor to upgrade gas lines and facilities throughout Columbia’s delivery system. Envista's innovative technology enables Columbia Gas of Pennsylvania to manage renewal projects internally while introducing a new method to share projects and schedules with municipalities, the Department of Transportation and other utilities working in the same road "right of way." This capability translates into less digging in neighborhoods and streets, and minimizes the impact of work on local communities.

"We have been looking for technology that would help us manage our gas infrastructure improvement program, and the Envista software provides a timely solution to our immediate needs," said Rob Mooney, Manager, Field Engineering for Columbia Gas of Pennsylvania. "It provides us the ability to share project schedules with other operators of underground infrastructure such as local municipalities, the Department of Transportation and other utilities. This technology immediately delivers benefits through improved coordination of construction projects reducing the impact to commuters around our work zones.”

“We are proud to work with Columbia Gas of Pennsylvania on their “Pipeline to the Future” and we believe that our technology was tailor-made for an infrastructure program of this magnitude. Envista facilitates long term capital planning, and delivers the automation and best practices needed in the industry," said Envista CEO Rick Fiery. "We are confident our solution will deliver unprecedented efficiencies in managing and coordinating infrastructure renewal for decades to come."
