Midstream Pipeline and Gathering System Insurance: Pollution Liability, Business Interruption, and Third-Party Damage

What are the main insurance exposures for a midstream operator?

Four, and they belong to different policies. Physical damage to pipelines, compressors, and processing equipment is a property and energy property exposure, complicated by the fact that buried pipe is difficult to value and to inspect. Pollution liability covers third-party cleanup, bodily injury, and property damage from a release, which general liability handles poorly because of the pollution exclusion. Business interruption covers lost throughput revenue, and for a midstream operator that includes contractual exposure to producers whose gas could not move. Third-party liability covers damage the operator causes to others, including the classic scenario of a line strike during someone else's excavation and the reverse, where the operator's own construction damages a third party's facility.

• Energy property covering pipelines, compressor stations, processing plants, and control systems.
• Pollution legal liability for third-party cleanup, injury, and property damage from a release.
• Business interruption and contingent business interruption on throughput revenue.
• General and excess liability for third-party bodily injury and property damage.
• Control of well coverage where the operator also has wellhead interests.

Why does general liability not cover a pipeline release?

Because of the absolute pollution exclusion, which appears in essentially every commercial general liability form and removes coverage for bodily injury and property damage arising from the discharge, dispersal, seepage, migration, release, or escape of pollutants. Hydrocarbons are pollutants. A release from a gathering line that contaminates soil, reaches groundwater, or damages a landowner's property is therefore outside general liability almost entirely. What responds is a pollution legal liability policy, sometimes written as environmental impairment liability, and those policies are claims-made with their own structure. Two features deserve attention. First, whether coverage includes gradual releases discovered later, not just sudden ones, since pinhole leaks in buried pipe are often found long after they started. Second, whether the policy covers cleanup of your own property, which many forms exclude or sublimit.

• The general liability pollution exclusion removes essentially all release-related coverage.
• Pollution legal liability is claims-made, with a retroactive date that must reach back far enough.
• Confirm whether gradual and historical releases are covered, not just sudden events.
• Confirm whether on-site cleanup of owned property is included.
• Watch for exclusions tied to known conditions at the time of binding.

How should business interruption be structured for a gathering system?

Around throughput, and with contingent coverage in both directions. Your revenue depends on volume moving through the system, and volume depends on producers upstream continuing to produce and on downstream plants and takeaway capacity continuing to accept. A failure anywhere in that chain stops your revenue even when your own assets are intact. Contingent business interruption covers loss caused by damage at a supplier's or customer's facility, and for midstream operators the named locations should include the processing plants, fractionators, and interconnects that matter most. Then look at the indemnity period. Replacing a compressor or a specialty section of pipe can take months, and long-lead equipment in this sector regularly runs 30 to 60 weeks. A 12 month indemnity period is the minimum, and 18 to 24 months is often appropriate.

• Measure business interruption on throughput revenue, including demand and reservation charges.
• Add contingent business interruption naming upstream producers and downstream plants and interconnects.
• Set the indemnity period against equipment lead times, not construction time.
• Include extra expense for bypass, trucking, or alternate routing during an outage.

What third-party damage exposures do operators underestimate?

Line strikes in both directions, and they behave differently. When a third party strikes your line, you have a property and business interruption loss and a recovery action against the excavator, whose liability insurance may be inadequate relative to the loss. When your own contractor strikes a third party's facility, you own the resulting liability, including their business interruption, and these claims escalate quickly if the struck facility is a fiber line, a water main, or a higher-pressure transmission line. The other underestimated exposure is right-of-way and landowner liability. Gathering systems cross private property under easements, and landowner claims over surface damage, cattle loss, crop loss, and diminished property value arise routinely, sometimes years after construction. Many of those claims allege contamination, which pushes them out of general liability and into the pollution policy.

How do underwriters evaluate a midstream submission?

They evaluate integrity management before they evaluate financials. Expect detailed questions about the age, material, and coating of the pipe, the inspection and pigging program, cathodic protection, leak detection technology, and whether you operate under a formal integrity management program. Regulated transmission lines carry mandated inspection requirements, while many gathering lines historically fell outside federal jurisdiction, and underwriters now ask pointedly about lines in that category. They will ask about SCADA coverage, remote shut-in capability, and response time to an alarm. They will ask about the produced water and condensate handling, since those releases drive a large share of environmental claims. And they will ask for your loss history including near misses, because a pattern of small releases predicts a large one.

• Pipe age, material, wall thickness, coating condition, and prior repair history.
• In-line inspection and pigging schedule, plus cathodic protection survey results.
• Leak detection method, SCADA coverage, and remote isolation capability.
• Integrity management program documentation and regulatory inspection history.
• Release history including reportable and non-reportable events.

If your midstream program was written around property and general liability without a purpose-built pollution policy, the largest exposure on the system is uninsured.
