It listed 15 receipt points as being constrained (see the bulletin board for details). Effective with the start of Wednesday’s gas day CenterPoint limited capacity on the affected section of Line AD to 70,000 Dth/d until further notice, but said it anticipates no impact on its ability to meet primary firm receipt obligations or overall receipt entitlements in the West 1 Pooling Area.
