On the basis of the inspection, PHMSA has identified the apparent inadequacy found within Sunoco’s plans or procedures, as described below: 1. § 195.202 Compliance with specifications or standards. Each pipeline system must be constructed in accordance with comprehensive written specifications or standards that are consistent with the requirements of this part. Sunoco’s written construction standards were inadequate. Specifically, Appendix B: Corrosion Control Requirements (Revision No.: 0 and Revision Date: 11/30/12) of Sunoco’s Inspector Manual (Appendix B) failed to provide adequate thickness requirements for the application of Powercrete R95 coating in non-bore locations in accordance with §§ 195.557(a) and 195.559(d). Section 195.557(a) states: Except bottoms of aboveground breakout tanks, each buried or submerged pipeline must have an external coating for external corrosion control if the pipeline is--#

The requirements for Powercrete R95 stated in part: “[a]pplied final thickness: 52 mil for HDD installation, may be less for non bore installations.” Sunoco’s requirement for non-bore HDD installation did not specify a final minimum thickness. Hence, by not specifying a final minimum thickness for Powercrete R95 coating on pipe in non- bore locations, Sunoco failed to prepare an adequate construction standard as required by § 195.202 pertaining to §§ 195.557(a) and 195.559(d). Sunoco must revise its written construction standard to address this inadequacy. Response to this Notice This Notice is provided pursuant to 49 U.S.C. § 60108(a) and 49 C.F.R. § 190.206.
