SUPPLEMENTARY INFORMATION:

I. Background

    The purpose of this advisory bulletin is to remind all owners and 
operators of gas and hazardous liquid pipelines, particularly those 
with facilities located in offshore and inland areas, about the serious 
safety-related issues that can result from the passage of hurricanes. 
That includes the potential for damage to offshore platforms and 
pipelines and onshore pumping stations, compressor stations, and 
terminals.
    Operators of gas and hazardous liquid pipelines have a general 
obligation to identify any conditions that can adversely affect the 
operation of their pipelines and to take appropriate corrective 
measures upon discovering such conditions. Specifically, Sec.  192.613 
of the gas pipeline safety regulations states that ``[e]ach operator 
shall have a procedure for continuing surveillance of its facilities to 
determine and take appropriate action concerning * * * unusual 
operating and maintenance conditions,'' and that ``[i]f a segment of 
pipeline is determined to be in unsatisfactory condition but no 
immediate hazard exists, the operator

[[Page 54532]]

shall initiate a program to recondition or phase out the segment 
involved, or, if the segment cannot be reconditioned or phased out, 
reduce the maximum allowable operating pressure in accordance with 
Sec.  192.619(a) and (b).'' Section 195.401(b)(1) of the hazardous 
liquid pipeline safety regulations states that ``[w]henever an operator 
discovers any condition that could adversely affect the safe operation 
of its pipeline system, it must correct the condition within a 
reasonable time. However, if the condition is of such a nature that it 
presents an immediate hazard to persons or property, the operator may 
not operate the affected part of the system until it has corrected the 
unsafe condition.'' Section 195.401(b)(2) further states that ``[w]hen 
an operator discovers a condition on a pipeline covered under [the 
integrity management requirements in] Sec.  195.452, the operator must 
correct the condition as prescribed in Sec.  195.452(h).''
    Operators of shallow-water gas and hazardous liquid pipelines in 
the Gulf of Mexico and its inlets have a specific obligation to 
``prepare and follow a procedure to identify [their] pipelines * * * 
that are at risk of being an exposed underwater pipeline or a hazard to 
navigation * * * [and to] conduct appropriate underwater inspections * 
* * [of those pipelines] based on the identified risk[;]'' and upon 
discovering that ``its pipeline is an exposed underwater pipeline or 
poses a hazard to navigation,'' to promptly report the location of that 
pipeline to the National Response Center, to mark its location, and to 
ensure its reburial within a specified time. 49 CFR 192.612, 195.413.
    Hurricanes can adversely affect the operation of a pipeline and 
require corrective action under Sec. Sec.  192.613 and 195.401. 
Hurricanes also increase the risk of underwater pipelines in the Gulf 
of Mexico and its inlets becoming exposed or constituting a hazard to 
navigation under Sec. Sec.  192.612 and 195.413. The concentration of 
U.S. oil and gas production, processing, and transportation facilities 
in the Gulf of Mexico and onshore Gulf Coast means that a significant 
percentage of domestic oil and gas production and processing is prone 
to disruption by hurricanes.
    In 2005, Hurricanes Katrina and Rita caused significant damage to 
the oil and gas production structures. The onshore damage caused a 
significant impact in the ability of the oil and gas industry to 
respond due to the lack of resources, personnel, and infrastructure, as 
well as significant damage to onshore processing facilities and power 
supplies. There were significant competing resource needs with the 
impacts caused by the devastation of New Orleans and western Louisiana/
eastern Texas shore communities that normally provide the services and 
supplies for the industry.

II. Advisory Bulletin (ADB-11-05)

    To: Owners and operators of gas and hazardous liquid pipeline 
systems.
    Subject: Potential for damage to pipeline facilities caused by 
hurricanes.
    Advisory: All owners and operators of gas and hazardous liquid 
pipelines are reminded that pipeline safety problems can occur by the 
passage of hurricanes. Pipeline operators are urged to take the 
following actions to ensure pipeline safety:
    1. Identify persons who normally engage in shallow-water commercial 
fishing, shrimping, and other marine vessel operations and caution them 
that underwater offshore pipelines may be exposed or constitute a 
hazard to navigation. Marine vessels operating in water depths 
comparable to a vessel's draft or when operating bottom dragging 
equipment can be damaged and their crews endangered by an encounter 
with an underwater pipeline.
    2. Identify and caution marine vessel operators in offshore 
shipping lanes and other offshore areas that deploying fishing nets or 
anchors and conducting dredging operations may damage underwater 
pipelines, their vessels, and endanger their crews.
    3. If operators should need to bring offshore and inland 
transmission facilities back online, check for structural damage to 
piping, valves, emergency shutdown systems, risers and supporting 
systems. Aerial inspections of pipeline routes should be conducted to 
check for leaks in the transmission systems. In areas where floating 
and jack-up rigs have moved and their path could have been over the 
pipelines, review possible routes and check for sub-sea pipeline damage 
where required.
    4. Operators should take action to minimize and mitigate damages 
caused by flooding to gas distribution systems including the prevention 
of overpressure of low pressure and high pressure distribution systems.
    PHMSA would appreciate receiving information about any damage to 
pipeline facilities caused by hurricanes. The Federal pipeline safety 
regulations require that operators report certain incidents and 
accidents to PHMSA by specific methods. Damage not reported by these 
methods may be reported to John Hess, Director for Emergency Support 
and Security, 202-366-4595 or by e-mail at PHMSA.OPA90@dot.gov.
