In accordance with the Outer Continental Shelf Lands Act (OCSLA), 43 U.S.C. 1331 et seq. and its implementing regulations (30 CFR part 250), BSEE is responsible for regulating many activities on the OCS in order to ensure the orderly and expeditious development of oil and natural gas resources in a safe and environmentally responsible manner. Among other responsibilities, BSEE enforces regulations for decommissioning of pipelines and related infrastructure on the OCS seabed, as well as regulations for decommissioning of wells, platforms and other facilities. (See 30 CFR part 250, subpart Q (§§ 250.1700—250.1754).)
The Subpart Q regulations require that an operator decommission and remove pipelines, wells, platforms and other facilities when they are no longer useful for operations. (See 30 CFR 250.1703.) The operator must conduct these decommissioning activities in a manner that is “safe, does not unreasonably interfere with other uses of the OCS, and does not cause undue or serious harm or damage to the human, marine or coastal environment.” (Id. § 250.1703(g).) Among other things, the decommissioning regulations require the removal of all “facilities.” (See, e.g., id. §§ 250.1703(c), 250.1725.) Section 250.1700(c) defines “facility” to include pipeline risers and any other Start Printed Page 67344equipment (e.g., umbilicals) that constitute an obstruction.
The Subpart Q decommissioning regulations also require lessees, owners of operating rights, and holders of rights-of-way to clear from the seafloor all “obstructions” created by a lease or pipeline right-of-way operations. (See id. § 250.1703(e).) 
Section 250.1700(b) defines “obstructions” as including “structures, equipment or objects” (e.g., umbilicals, pipelines, and pipeline valves and risers) that, “if left in place, would hinder other users of the OCS.” Other uses of the OCS may include, but are not limited to, future oil and gas operations, U.S. military activities, renewable energy activities, transportation and communication projects, commercial and recreational fishing, and possibly other recreational uses.
Pursuant to § 250.1750, however, a pipeline may be decommissioned-in-place (i.e., without removal), provided that the Regional Supervisor determines (upon application) that leaving the pipeline in place would “not constitute a hazard (obstruction) to navigation and commercial fishing operations, unduly interfere with other uses of the OCS, or have adverse environmental effects.” Section 250.1751 then specifies the process for applying for BSEE's approval to decommission a pipeline in place and the requirements for decommissioning in place (DIP). Consistent with this process, § 250.1751(g) requires the removal of “pipeline valves and other fittings that could unduly interfere with other uses of the OCS.” Thus, § 250.1751(g) permits DIP of pipeline valves and other fittings that do not “unduly interfere” with other uses of the OCS.
In addition, BSEE has broad authority under 30 CFR 250.142 to grant departures from the operating requirements of its regulations, under appropriate circumstances, upon written request to the District Manager or the Regional Supervisor. Such departure requests may include requests to the Regional Supervisor to decommission-in-place certain pipeline-related infrastructure beyond pipeline valves and other fittings. Pipeline-related infrastructure includes umbilicals, subsea production manifolds, pipeline end terminations (PLETs), pipeline end manifolds (PLEMs), subsea umbilical termination assemblies, pumps, and electrical or hydraulic flying leads.
Deepwater developments, in particular, often involve extensive networks of pipeline-related infrastructure including, but not limited to, umbilicals, subsea production manifolds, PLETs, and PLEMs. Of the approximately 80 deepwater developments in the Gulf of Mexico, some are at—or are nearing—the end of their service lives. BSEE has received an increasing number of applications to allow DIP of certain pipeline-related infrastructure in such deepwater operations. Currently, BSEE's Gulf of Mexico Region has at least 10 such requests now pending, some of which include more than one piece of pipeline-related infrastructure. In general, such requests assert that, although technically feasible, removal is either unnecessary or less safe than DIP, on the grounds that leaving the pipeline-related infrastructure in place would not pose safety or environmental hazards or obstruct the OCS by hindering other uses.
Although BSEE does not anticipate any changes to its longstanding policies for the approval of requests to decommission pipelines (i.e., the line pipe) in place pursuant to § 250.1751, BSEE is considering whether—and under what circumstances—DIP of pipeline valves and fittings and other pipeline-related infrastructure in deepwater could be considered appropriate. In particular, to determine whether it is appropriate for pipeline valves and fittings to be decommissioned-in-place in accordance with § 250.1751(g), BSEE must assess whether the valves and fittings would unduly interfere with other uses of the OCS. Similarly, to determine whether it is appropriate to grant departure requests to allow DIP of other pipeline-related infrastructure in deepwater pursuant to § 250.142, BSEE must assess whether the pipeline-related infrastructure would constitute a hazard (obstruction) or otherwise unduly interfere with other uses of the OCS, or would have adverse safety or environmental consequences if left in place.
BSEE is also identifying technical considerations that may be relevant to BSEE's determinations as to whether it would be appropriate to approve requests to allow DIP of pipeline valves and fittings (pursuant to § 250.1751(g)) and other pipeline-related infrastructure (pursuant to § 250.142) in deepwater. For instance, BSEE has determined that water depth is an important technical factor in making such determinations; i.e., the greater the water depth, the less chance that DIP of pipeline valves and fittings or other pipeline-related infrastructure would cause obstructions or interfere with present or future uses of the OCS. Accordingly, BSEE is considering whether to apply a tiered approach to consideration of requests to approve DIP in deepwater based on water depth (e.g., in depths from 600 feet/182 meters) to 2625 feet/800 meters) and in depths greater than 2625 feet), with justifications for approvals being potentially less stringent in the greatest depths (i.e., where obstructions to navigation or commercial fishing or other activities are significantly less likely to occur than at shallower depths).
However, many variables and site-specific factors—in addition to water depth—can affect whether DIP is appropriate in a given case. For example, the size and location of pipeline-related infrastructure may also be important technical considerations. Some pipeline-related infrastructure is extremely large (e.g., subsea manifolds may occupy up to about 72,000 cubic feet and reach heights of up to 35 feet), potentially increasing the possibility of obstacles or other interference with use of the OCS. In some cases, especially for very large projects, it is possible that certain pipeline-related infrastructure may abut or cross multiple lease sections. Leaving such equipment in place, even in deepwater, potentially could create obstacles or otherwise interfere with use of the OCS (e.g., by inhibiting bidding on these tracts at Start Printed Page 67345future lease sales or discouraging exploration, development, or production under other leases or by interfering with potential future renewable energy activities).
Thus, the issues related to DIP of pipeline valves and fittings and other pipeline-related infrastructure in deepwater are potentially complex, especially in light of the size and scope of some projects. Accordingly, BSEE invites the public to submit relevant information and comments on such issues in order to help BSEE establish a consistent and reasonable approach to consideration of requests to allow DIP of pipeline valves and fittings and other pipeline-related infrastructure in deepwater.
II. Request for Information
BSEE would appreciate your views, and any relevant technical information you can provide, on whether and under what circumstances it would be appropriate for BSEE to approve DIP of pipeline valves and fittings (pursuant to § 250.1751(g)) and of other pipeline-related infrastructure (pursuant to § 250.142) in deepwater. Among other issues, BSEE would appreciate comments and information related to whether DIP of pipeline valves and fittings or other pipeline-related infrastructure in deepwater: (1) Could increase (or decrease) safety or environmental risks as compared to decommissioning by removal; or (2) could interfere with navigation, create an obstruction, or otherwise unduly interfere with present or future uses of the OCS.
Please be as specific as possible in expressing your views and in the other information you provide. For example, please consider how your views or information could vary depending on specific circumstances, such as the water depth at which decommissioning takes place. Wherever possible, please provide relevant factual support for your views.
