WARNING LETTER
OVERNIGHT EXPRESS DELIVERY
November 2, 2016
Ms. Stephanie Timmermeyer
VP, Safety and Regulatory Compliance
Transcontinental Gas Pipe Line Company
525 Central Park Drive
Oklahoma City, OK 73105
CPF 1-2016-1008W
Dear Ms. Timmermeyer:
From September 15 through 19, 2014, a representative of the Pipeline and Hazardous Materials Safety
Administration (PHMSA), pursuant to Chapter 601 of 49 United States Code, inspected Williams’s
Transcontinental Gas Pipe Line Company’s (Transco) replacement of sections of mainlines A, B, and C
within Unit #2881 - Elliott City in Owings Mills, MD.
As a result of the inspection, it appears that you have committed a probable violation of the Pipeline
Safety Regulations, Title 49, Code of Federal Regulations. The items inspected and the probable
violation is:
1. §192.303 Compliance with specifications or standards.
Each transmission line or main must be constructed in accordance with comprehensive
written specifications or standards that are consistent with this part.
Transco failed to construct each transmission line or main in accordance with comprehensive written
specifications or standards that are consistent with this part.
Specifically, Transco failed to follow its construction procedures. During the inspection, the PHMSA
inspector reviewed Transco’s construction specifications and records related to the replacement of a
section of transmission line C in Owings Mills, MD.
Transco’s construction procedure, titled “Volume 890 – Construction Specification for Online Pipeline
Inspection, revised 7/28/14, paragraph 1.1.9,” states in part “. . . poly tanks, made of non-conducting
material, will not be used for venting, catching, or storing pipeline liquids.”
During a field inspection on 9/16/2014, the PHMSA inspector observed a poly tank connected to the
pipeline at MP 1631.94. Transco’s Construction Daily Progress Report #20 stated, “Manifolds were
welded onto both ends of old ML ‘C’ and a cleaning pig was run to check for fluids - no liquids found.”
PHMSA informed Transco’s Chief Inspector of the failure to follow Transco’s construction
specifications. Transco informed PHMSA that the operation did not result in the disposition of any



1-2016-1008W
condensate or liquid from mainline C into the poly tank, and that a decision had been made not to utilize
the poly tank for liquid/condensate removal operations, which were pending for the replacement sections
on Line A and Line B.
Under 49 United States Code, § 60122, you are subject to a civil penalty not to exceed $205,638 per
violation per day the violation persists up to a maximum of $2,056,380 for a related series of violations.
For violation occurring between January 4, 2012 to August 1, 2016, the maximum penalty may not
exceed $200,000 per violation per day, with a maximum penalty not to exceed $2,000,000 for a related
series of violations. For violations occurring prior to January 4, 2012, the maximum penalty may not
exceed $100,000 per violation per day, with a maximum penalty not to exceed $1,000,000 for a related
series of violations. We have reviewed the circumstances and supporting documents involved in this
case, and have decided not to conduct additional enforcement action or penalty assessment proceedings at
this time. We advise you to correct the item identified in this letter. Failure to do so will result in
Transco being subject to additional enforcement action.
No reply to this letter is required. If you choose to reply, in your correspondence please refer to CPF 1-
2016-1008W. Be advised that all material you submit in response to this enforcement action is subject to
being made publicly available. If you believe that any portion of your responsive material qualifies for
confidential treatment under 5 U.S.C. 552(b), along with the complete original document, you must
provide a second copy of the document with the portions you believe qualify for confidential treatment
redacted and an explanation of why you believe the redacted information qualifies for confidential
treatment under 5 U.S.C. 552(b).
