So, the progression seems to be a less restrictive approach, from anyone bringing the pollutants onto the job location to the named insured, the contractor working for the named insured, and the named insured's designated employee. The broad purpose of the exclusion over the years remains the same, namely to exclude coverage for bodily injury and property damage claims due to the release or escape of pollutants from the job location where the named insured or the named insured's contractors are working if the pollutants are brought onto the job site by those parties. However, the application of the exclusion now depends on specifically designated persons.
