PHMSA received a special permit modification request from KMLP, owned by Kinder Morgan, Inc., to modify special permit Condition 28(a) of the existing special permit, PHMSA-2006-25803. KMLP requests a modification of Condition 28(a) to allow an increase in the amount of H2 S in the pipeline gas stream from 0.25 grains to 0.5 grains per 100 standard cubic feet. The requested amount of H2 S in the KLMP pipeline gas stream is less than what is required in 49 CFR 192.620(d)(5)(v)(C), “Controlling Internal Corrosion.”

The special permit was issued to KMLP on April 13, 2007, to waive compliance with 49 CFR 192.111 and 192.201(a)(2)(i) for Class 1 locations along the Leg 1 segment of the KMLP. The KMLP Leg 1 segment is a 137-mile, 42-inch diameter pipeline that is located in Calcasieu, Cameron, Jefferson Davis, Acadia, and Evangeline Parishes in Louisiana. The KMLP Leg 1 segment has a maximum allowable operating pressure of 1,440 pounds per square inch gauge in the special permit segment.

The special permit modification request and existing special permit with conditions for the KMLP are available for review and public comment in the Docket No. PHMSA-2006-25803. PHMSA invites interested persons to review and submit comments in the docket regarding the special permit modification request. Please include any comments on potential safety and environmental impacts that may result if the special permit modification is granted. Comments may include relevant data.

Before issuing a decision on the special permit modification request, PHMSA will evaluate all comments received on or before the comment closing date. Comments received after the closing date will be evaluated, if it is possible to do so without incurring additional expense or delay. PHMSA will consider each relevant comment it receives in making its decision to grant or deny this special permit modification request.
