**body:**

CenterPoint Energy is working with the Railroad Commission of Texas (RRC) to correct the designation of a total of 138 miles under OPID 32024, in the state of Texas, to distribution as this mileage does not meet the definition of a transmission line. The designation correction provides consistency across the company's footprint and the application of the appropriate integrity management program requirements. The mileage was split into two categories: pipelines with documentation completely under 20% SMYS; and pipelines where some segments in the system needed material verification or other efforts to verify attribution and percent SMYS, or segments that were connected to such a system. Currently, 62 miles have been corrected in cooperation with the RRC. An additional 76 miles are scheduled for review in December with the RRC Field Inspector. This change results in an 87% decrease in High Consequence Area (HCA) mileage in OPID 32024 and thus is a significant change in accordance with our Integrity Management plan as it exceeds a 25% change in HCA mileage. Please consider this the communication of a significant program change per 49 CFR 192.909.
