Chemical Manufacturers

Chemical manufacturers are exposed to numerous environmental risks, including using and storing chemicals and waste generation. Accidental discharge of chemicals can contaminate soil or groundwater or migrate to on-site drains, drywells, or surface waters. These discharges can impact sources of drinking water and natural resources. Processes involved in manufacturing chemicals may generate hazardous air emissions, which can be released into the atmosphere through improper emissions control or operational accidents. Environmental liability may result from improper storage or mixing of incompatible materials, releases on-site, or during transport and waste disposal. Manufacturers may also have above and underground tanks which can leak into the underlying soil and groundwater, leading to numerous environmental contamination issues.

On-Site Leaks

Releases of chemicals, petroleum products, or wastes from aboveground or underground storage tanks, process equipment, containers, wastewater treatment systems, piping systems, drains, or other areas of a chemical manufacturing facility could impact soil or groundwater, result in toxic air releases, migrate off-site, harm municipal sanitary sewers, or impact surface waters, resulting in costly cleanup claims, third-party suits, natural resource damages, and civil fines.

Accidental Releases During Transport

Accidental releases during the transportation of products or wastes from a manufacturing facility due to improper cargo securement, a loose valve, or vehicle upsets or overturns can result in environmental liability.

Air Emissions

Air emissions can emanate from the chemicals stored or the manufacturing process or from releasing exhaust or toxic gases from equipment. Chemicals may be stored that produce a vapor cloud if accidentally released. Vehicles and powered equipment, such as forklifts, trucks, and cranes, may be used at facilities. These types of internal combustion vehicles are powered by diesel or propane, which can emit carbon monoxide gas and diesel particulates. Improper controls or malfunctioning equipment can result in exceedances and regulatory violations. Air emissions or a vapor cloud release can pose health hazards to third parties.

Product Liability

Chemical manufacturers can have environmental exposures from products they manufacture or distribute if pollution conditions result from the products’ use, defect or deterioration, or the failure of the product packaging. Product pollution claims include environmental damage, third-party bodily injury, and property damage. Many General Liability and Product Liability insurance policies deny coverage for cleanup, bodily injury, and property damage and defense arising from using or discharging pollutants from a chemical product.

Flammables

Incompatible chemicals are prone to react violently or produce toxic byproducts/gases when stored together or mixed. Flammable products may result in a fire that spreads and releases other contained materials, emitting toxic fumes and smoke from the materials stored at the site or due to a mix of materials that occurs due to the fire. Firefighting water or foam could create contaminated run-off that spreads to nearby storm drains or properties, resulting in environmental cleanup and tort liability.

Wastewater Management

Cleaning storage tanks and processing equipment may generate wastewater or sludge. Wastewater treatment systems may be present at facilities, or these waste materials may be taken to a non-owned disposal facility or wastewater treatment facility. Releases of insufficiently treated wastewater could occur, or spills could occur during cleaning, transport, or transfer from wastewater storage areas and create environmental risks. Improper waste disposal could lead to environmental liability or legal consequences for violating regulatory requirements.

Hazardous Waste Management

Chemical manufacturers may generate hazardous or regulated wastes requiring special disposal procedures. Improper waste disposal could lead to environmental liability or legal consequences for violating regulatory requirements. A chemical manufacturer can become a Potentially Responsible Party (PRP), liable for clean-up costs in the environmental cleanup of a non-owned disposal (NOD) facility where they sent wastes.

Off-Site Contaminant Migration

Many chemical manufacturing facilities are located in industrial areas, and contaminants from neighboring facilities could migrate to the manufacturer’s property. If the neighboring business owner is not properly insured or goes bankrupt, the cost of cleanup could fall on the manufacturer for their property. Additionally, impacts from historic operations could be present, potentially leaving the current operator liable for cleanup under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA).

Vandalism

Inadequate security at a facility may lead to vandalism. Damage to facility equipment, such as aboveground tanks or containers of chemicals, can result in environmental releases.

Illicit Abandonment

Illicit abandonment is the illegal dumping of pollutants on a property by a third party. It can become the property owner’s burden for cleanup and third-party bodily injury or property damage if law enforcement cannot find the originator of the waste.

Stormwater Ruff-off

Stormwater run-off could come in contact with chemicals, debris, fueling areas, wastes, and other outside storage at chemical manufacturing facilities. If stormwater is not properly controlled, contained, or pre-treated before discharge into sanitary or storm drainage systems, it can pollute soil and groundwater or discharge directly into surface waters, impacting human health and aquatic systems.

Claims Scenarios & Examples

A chemical blending and manufacturing company began producing a new chemical blend recipe that had only been small-volume tested. The chemical mix began overheating and combusting during initial production, releasing flammable gases. A flash fire engulfed the facility, and the fire department poured millions of gallons of water on the fire, which became contaminated with raw materials and products. The water flowed into an adjacent stormwater culvert that discharged to a stream and two ponds of an adjacent landowner. Cleanup costs totaled several million dollars.
A neoprene, synthetic rubber manufacturing facility consistently exceeded the agreed air emissions standard for chloroprene, a component chemical. The cancer rates in the surrounding town were found to be excessively high. A civil action lawsuit was filed against the chemical manufacturer for alleged violations of the Clean Air Act and state environmental laws.
A chemical manufacturing facility was storing a mixture of chemicals in an aboveground storage tank. The chemical mixture tank leaked and released the chemical into an adjacent river. The river is a drinking water source, and 300 people sought medical treatment for potential exposure to the chemical. Additionally, approximately 93,000 customers in nine counties were advised to restrict tap water used for drinking, cooking, and bathing for an extended period. The state fined the chemical manufacturer $900,000, and several lawsuits have been filed against the manufacturer.
An industrial coatings manufacturer delivered a product to a customer when the tanker truck was involved in an accident. The chemical spilled onto the roadway and to a stormwater drain that discharged to a nearby creek. The chemical company incurred significant emergency response and remedial action costs.
The fill line for sodium hypochlorite was left open during sulfuric acid delivery to a chemical manufacturer. The two chemicals were inadvertently mixed, forming a toxic cloud of chlorine gas and other chemicals. One hundred forty people in the vicinity were injured, resulting in significant claims against the chemical manufacturer. In addition, almost $2 million in fines were sought.
An underground storage tank at a chemical manufacturing facility leaked solvent into the surrounding soil and groundwater. The solvent in groundwater migrated to the neighboring property. Cleanup and monitoring of the resulting contamination on and off-site totaled more than $1 million.
A chemical manufacturer generated hazardous wastes over many years and sent them to an approved landfill, which was mismanaged. The landfill had a major release and was listed as a Superfund site. As a result, the chemical manufacturer became a potentially responsible party in the cleanup of the landfill due to the waste they sent there over time.
Two explosions occurred at a petrochemical plant in a unit that held butadiene. The explosions caused a fire that injured some nearby residents and resulted in the evacuation of businesses and residents within a four-mile radius of the plant. The company was liable for the cleanup. Additionally, the state attorney general filed a lawsuit against the company for the natural resource damages and impacts on human health caused by the fire and state costs to investigate and prosecute the claim.
An earthquake occurred in the area of a chemical manufacturing plant and caused damage to an aboveground storage tank at the facility. The tank spilled 8,200 gallons of hydrochloric acid. Emergency response and cleanup costs totaled more than $300,000.
