WITHDRAWAL of NOTICE LETTER
CERTIFIED MAIL - RETURN RECEIPT REQUESTED
September 14, 2012
Mr. John Filiatrault
Vice President CO2 Supply & Pipelines
Denbury Onshore, LLC
5320 Legacy Drive
Plano, Texas 75024
CPF 2-2012-5011
Dear Mr. Filiatrault:
On August 9, 2012, the Pipeline and Hazardous Materials Safety Administration (PHMSA),
Southern Region issued Denbury Onshore, LLC (Denbury) a Notice of Probable Violation
(NOPV) for a probable violation of the federal pipeline safety regulations in 49 CFR Part 195.
The NOPV pertained to Denbury’s North East Jackson Dome (NEJD) carbon dioxide pipeline
in Mississippi. It cited Denbury under §195.64(c)(1)(ii) for failing to notify PHMSA not later
than 60 days before beginning construction of more than 10 miles of a new hazardous liquid
pipeline. Denbury notified PHMSA on July 16, 2012 after it began construction on
July 11, 2012. This notification was required no later than May 12, 2012.
In reviewing Denbury’s response to the PHMSA Southern Region dated September 6, 2012,
we noticed that the regulation in §195.64(c)(1)(ii) could be confusing as to its applicability to
carbon dioxide pipelines because it refers to “a new hazardous liquid pipeline” but the
definition of a “hazardous liquid” in §195.2 does not include carbon dioxide. Meanwhile,
§195.64(c)(1)(iii) requires the reporting of the “Construction of a new pipeline facility” and
the definition of “pipeline facility” in §195.2 does include new pipe used in the transportation
of carbon dioxide.
That said, the PHMSA Southern Region hereby withdraws the NOPV and this case is now
closed.
Sincerely,
Wayne T. Lemoi
Director, Office of Pipeline Safety
PHMSA Southern Region
