A detailed coverage agreement covering damages resulting from the release or escape of contaminants is a necessary component of true environmental insurance. At a minimum, this coverage applies to:
- Bodily Injury: Covers physical harm to individuals, often enhancing the definition used in general liability (GL) policies.
 - Property Damage: Covers damage to property, often enhancing the GL policy's definition.
 - Cleanup Costs: Covers expenses required by environmental laws, with possible enhancements depending on the business class.
 - Defense Costs: Traditionally included within the liability limit, covering legal defense expenses.

 - Business interruption
 - Loss of rents
 - Extra expenses
 - Reputational damage
 - Midnight dumping on insured locations
 - Coverage for fungi/bacteria as defined pollutants
