  1. EPA Natural Gas Star Natural Gas Distribution Merrillville, IN June 3, 2003

  2. Sources of Natural Gas Emissions • Facility Damage • Leakage from mains and services • Leakage from Measurement/Regulation Facilities • Pneumatic Equipment • Purging Lines and Equipment

  3. Issues Unique to Gas Distribution • Lower Pipeline Pressures than Transmission • Unaccounted for Gas – Rate recovery • Large number of meters; no pressure temperature compensation • Mainlines located in urban settings • Higher level of customer visibility

  4. Current Approaches to Leakage • Managed as a Risk Based Aspect of the Business • Leakage can represent risk in the forms of potential personal/property damage • Potential nuisance issues • DOT /Operating Plans require established procedures for addressing leakage • Renewed focus on facility damage prevention

  5. EPA NG Star – A New Twist • Provides ability to document reductions in NG emissions • Provides voluntary partnership versus potential regulatory mandates for leakage reductions • Emphasizes environmental benefits gained from emission reductions as well as operational benefits • Creates potential of future emissions trading credits

  6. New Partners – How to Get Started • Canvass current operations to establish estimates on current reductions. • Use BMP’s/PRO’s already established to target additional potential areas for reduction.(flexibility to identify new ones) • Develop implementation plan. • Commit resources to accomplish plan objectives • Document results

  7. Gas Distribution BMPs/PROs • BMP I – Directed Inspection and Maintenance at Gate Stations • BMP II – Replacing leaking mains and services • BMP V – Replacing High Bleed Pneumatic Equipment • PROs – Partner Reported Opportunities • Relining of gas mains • Excess flow valves • Damage prevention

  8. Benefits of Partnership • Consistent action in light of corporate environmental policies • Improved performance in distribution systems with reduced leakage • Risk reduction associated with less leakage, fewer damaged facilities • Utilizing communication/PR opportunities featuring EPA Gas Star Logo and promotional materials. • Generates documented emissions reductions that can may be used in future in emissions trading credits.
