Pollution Liability for Landscapers: Pesticides, Fertilizer, and Herbicide Drift

Many landscaping companies assume their general liability policy covers them when a chemical spills, herbicide drifts onto a neighbor's property, or fertilizer washes into a storm drain. It does not. The pollution exclusion in the standard ISO CG 00 01 GL form removes coverage for the discharge, dispersal, or release of pollutants, and most carriers treat pesticides, herbicides, and fertilizer as pollutants under that language. This gap is not a technicality; it is one of the most commonly uncovered exposures in the landscaping industry. Our complete landscaping insurance guide covers the full coverage picture, but this post focuses specifically on the pollution gap in your general liability policy and how Contractors Pollution Liability (CPL) fills it.

Why Standard GL Does Not Cover Pollution Events

The ISO CG 00 01 pollution exclusion applies to the actual, alleged, or threatened discharge, dispersal, seepage, migration, release, or escape of pollutants. Most carrier policy forms define pesticides, herbicides, and fertilizers as pollutants. Common landscaping events that trigger this exclusion include:

• Herbicide drift. Wind carries herbicide overspray onto a neighboring property, damaging ornamentals, garden beds, or crops.
• Fertilizer runoff. Heavy rain moves fertilizer off a treated lawn into a storm drain, retention pond, or neighboring water feature.
• Pesticide exposure. A homeowner, child, or pet is exposed to pesticide residue after an application, resulting in a bodily injury claim.
• Chemical spill. Concentrated pesticide or herbicide is accidentally spilled on a client's driveway, turf, or hardscape during mixing or application.

When these events trigger a claim, the GL carrier typically denies coverage under the pollution exclusion. The business owner is then fully responsible for defense costs, remediation, and any settlement or judgment.

What Contractors Pollution Liability Covers

Contractors Pollution Liability (CPL) is a specialty policy form that covers third-party bodily injury and property damage caused by pollutants related to your work operations. For landscaping businesses, CPL typically covers:

• Third-party property damage. Herbicide drift that damages a neighbor's garden, farm crop, or landscaping. This is the most common landscaping CPL claim type.
• Third-party bodily injury. Pesticide or herbicide exposure that causes illness, irritation, or injury to a non-applicator (homeowner, child, neighbor, or bystander).
• Remediation costs. Clean-up and restoration expenses for a contaminated soil, turf, or water feature resulting from your chemical application.
• Defense costs. Legal defense expenses for covered claims, including regulatory agency proceedings in states that require notification of chemical incidents.

CPL does not cover pollution events caused by owned or operated vehicles (those go to commercial auto with a pollution endorsement) or intentional violations of environmental regulations.

Who Needs CPL?

Not every landscaping company carries the same chemical exposure. The EPA estimates that more than 1 billion pounds of pesticides are applied annually across U.S. commercial and residential operations (EPA Pesticides Industry Sales and Usage Report). For landscaping businesses that apply pesticides, herbicides, or fertilizers as part of routine service, CPL is not optional coverage. High-priority candidates include:

• Chemical applicators. Any landscaper applying pesticides, herbicides, or fertilizer to client properties on a regular basis.
• Properties near water. Operations near lakes, streams, irrigation ponds, or wetlands carry higher runoff risk and greater regulatory exposure if an incident occurs.
• Commercial account holders. Many property managers and HOAs now require CPL as a COI condition alongside GL and umbrella. Companies without it cannot bid those accounts.
• Operators near agricultural land. Herbicide drift onto neighboring crops can produce large property damage claims quickly, particularly during high-wind conditions.

CPL Policy Structure and Cost Factors

CPL is available as a standalone policy or as an endorsement to an inland marine policy. Key structural elements to understand before purchasing:

• Policy limits. Typically $1M per occurrence and $2M aggregate for small to mid-size landscaping operations. Commercial accounts requiring pollution liability often specify a minimum $1M limit on the COI.
• Claims-made form. Most CPL policies are claims-made rather than occurrence-based. The policy must be in force when the claim is reported, not just when the incident occurred. Retroactive date and tail coverage matter at renewal.
• Defense costs. Most CPL forms include defense costs within the policy limit rather than in addition to it. A large remediation claim can consume the limit quickly if defense costs are not managed separately.
• Premium drivers. Premium is influenced by revenue, the types of chemicals applied, number of application locations, proximity to water bodies, and claims history. OSHA recordable chemical incidents can affect pricing.

How TruPoint Approaches Pollution Liability

At TruPoint, CPL is part of every landscaping account review. Many landscaping business owners we work with had no idea their GL excluded pesticide and herbicide claims until we walked through the pollution exclusion language together. We assess chemical application frequency, service geography, proximity to water, and client contract requirements to determine whether CPL is necessary and at what limit. We then place it with carriers that specialize in contractor pollution, not general commercial writers that bolt it on as a low-limit endorsement. Contact TruPoint to review your current landscaping insurance coverage and identify any pollution gaps before a claim makes them impossible to miss.
