Effective January 1, 2015, the Infrastructure Replacement Rider has changed from a variable usage based rate of $0.082/ccf to a fixed monthly fee of $5.49 per member. This rate will be reflected on any bills generated after January 1, 2015. The Infrastructure Replacement Rider (IRR) is a separate charge that is calculated annually. The replacement rider is necessary to meet safety standards set by the Department of Transportation (DOT). Upgrades to the pipeline infrastructure will improve safety related conditions and reliability of service. Replacing an aging pipeline infrastructure that is prone to leakage will help save members money in the long run by reducing system gas loss. If you have any questions regarding this change please contact our Member Service Department at (800) 255-6815.
