2015 Heath Award Winner: Steve Redding Sr.

Heath Consultants  is pleased to announce that Steve Redding Sr., director of Pacific Gas and Electric’s (PG&E) leak management program, was named as the recipient of the 2015 Milton W. Heath Sr. Memorial Award at the American Gas Association’s annual Operations Conference and Biennial Exhibition in Grapevine, Texas.  This award recognizes individuals who have made outstanding contributions toward the detection, prevention and repair of natural gas leaks.

Redding was given the award for his achievements in reducing leaks through the use of cutting-edge technologies and the development of a management process unique to PG&E that is streamlining the company’s ability to respond to leaks. Redding and his team have delivered unprecedented results in the reduction of PG&E’s backlog of minor, non-hazardous leaks by 99 percent and the ability to find 80 percent more leaks than previous models, and in less time. Redding’s work to reduce leaks on the natural gas system not only improves the safety of the pipeline for PG&E customers and communities, it also contributes to a cleaner environment by reducing methane emissions.

Since beginning his career at PG&E in gas metering, Redding has held a number of leadership positions from overseeing major pipeline construction to serving as a general rate case witness. In his current role as director of leak management, Redding and his team work to increase system safety by finding and fixing leaks and identifying more effective leak detection technology.  Redding has a Business Management degree from St. Mary’s College in California.
