It Was in the Analysis

When I ended my first call with Robert Carson, I was unsettled—not because the facts were unclear, but because the coverage answer wasn't obvious at first glance. 
 
The pollution exclusion loomed large, and I knew the insurer might try to lean on it. But experience has taught me that exclusions don't operate in a vacuum; they operate in context. 
 
So, before calling Robert back, I did what I always do when the stakes are high: I went to my IRMI library. 
 
I pulled up the commercial general liability (CGL) HyperpolicyTM and followed the links to the detailed pollution exclusion analysis in IRMI's Commercial Liability Insurance publication. Line-by-line. Case law. Commentary. Practical application. 
 
That's when the picture sharpened. 
 
Yes, a caustic chemical escaped. 
 

Yes, it caused third-party property damage. 

 
But two facts mattered—critically. 
 
First, Carson & Son Contracting did not own, rent, or occupy the premises where the job was being performed. This wasn't their facility. They had no ongoing control over site operations beyond their excavation work. 
 
Second, Carson & Son was not engaged in the transport, storage, disposal, processing, or treatment of pollutants. They didn't bring the chemical to the site. They didn't manage it. They didn't release it as part of any pollution-related operation. The release occurred because an underground pipeline—owned and controlled by others—was punctured during routine construction activity. 
 
IRMI's analysis made it clear: Under these circumstances, the standard Insurance Services Office, Inc. (ISO), CGL pollution exclusion should not apply. 
 
This wasn't a guaranteed win. I knew the insurer might still push back. Pollution claims always invite scrutiny. But this was not the kind of environmental exposure the exclusion was designed to eliminate, and the policy language supported that conclusion. 
 
One thing helped more than anything else. 
 
At the last renewal, the underwriter had wanted to attach the Total Pollution Exclusion Endorsement. I had pushed back, and the underwriter had finally given in. The standard ISO pollution exclusion remained in play. Even though it is often called the "absolute pollution exclusion," it has exceptions that allow the policy to cover certain pollution releases. 
 
That negotiation mattered now. 
 
When I called Robert back, I chose my words carefully. 
 
"The workers compensation claim is solid, as we expected," I told him. "As for the damaged vehicles, I believe we have a strong case for coverage under your CGL. 
 
"But," I continued, "this may not be fast or easy. The insurer could challenge it, but if they do, we'll be prepared to bolster our position with supporting commentary from a trusted source." 
 
I explained the reasoning: the premises issue; the lack of pollutant handling; the intent of the exclusion. 
 
"For now," I said, "this is defensible." 
 
Then came the conversation we'd had before. 
 
"Robert, this is also why we keep talking about contractors pollution liability coverage." 
 
He didn't push back this time. 
 
"I want to revisit it," he said. "After this is over." 
 
When the call ended, I felt relief—and resolve. Relief that the policy will likely respond. Resolve to ensure the next renewal reflected the real-world exposures Carson & Son faced every day. 
 
Because exclusions don't just test coverage.  
They test preparation. 
 
And when the outcome depends on understanding not just what the policy says, but how it works in practice, having the right analysis matters just as much as having the right insurance.
