Concrete Batch Plants

A concrete batch plant mixes various ingredients to form concrete, including admixtures, sand, aggregate (rocks, gravel, etc.), fly ash, silica fume, slag, and cement. Concrete batch plants may experience accidental discharges of pollutants into on-site drains or monitoring wells that could enter waterways, surface water, and groundwater and eventually be released into drinking water sources. Cement batch plants may also have aboveground storage tanks (ASTs) or underground storage tanks (USTs) located at their facilities, which have the potential to lead to numerous environmental contamination issues. A major source of concern at these sites is the release of fugitive dust from the sand, cement, and other materials. Exposure can harm human health, domestic animals, and wildlife.

Environmental Exposures May Include:

Stormwater
Fugitive Dust
Heavy Equipment
Storage Tanks
Waste Management
Illicit Abandonment
Wastewater

Stormwater

Stormwater exposed to cement plant operations and chemical storage areas can become contaminated with sediments, oil, grease, and other materials and may be corrosive. Improper stormwater controls can allow run-off to enter water systems and cause natural resource damage. Surface run-off of soil particles (silt and sedimentation) can impair the proper functioning of stormwater drainage systems and cause ecological damage. Releases of contaminants from cement batch plants, such as heavy metals and limestone from storage silos, mixers, transfer equipment (conveyors), bins, and during loading to mixer trucks, can contaminate air, soil, groundwater, surface water and cause damage to third-party property located adjacent to the facility.

Fugitive Dust

Exposures may include unintended emissions of fugitive dust from the use of heavy equipment and the mixing of cement. Unintended emissions could occur due to malfunctions or breakdowns in process or air pollution control equipment or during the loading and loading, along with the transfer and handling, of materials such as fly ash, crushed rock, sand, or stone aggregate. Large releases of dust from cement batch plants can irritate the eyes, nose, and throat, and it can cause fatigue, nausea, vomiting, chest pain, and sleep difficulties in nearby third parties.

Heavy Equipment

Vehicles and heavy equipment used at cement batch plants can leak automotive fluids on the property. Pollutants such as heavy metals, solvents, fuels, oil, and grease can leach into the soil and contaminate groundwater or be collected by rainfall, creating contaminated stormwater that can enter storm drains and adjacent sites resulting in environmental liability.

Storage Tanks

Cement batch plants may use storage tanks for materials such as diesel fuel, oil, and gasoline. Leaks or spills from tanks, valves, tubes, and pipelines can leach into soil and groundwater or collect in stormwater run-off. Spills and leaks can occur during loading and unloading operations, overfilling a tank, or improper inspection or maintenance. Improper operation of the tanks can lead to fires and exposures, which can release hazardous emissions.

Waste Management

Collected wastes may contain hazardous materials and require special disposal procedures at an approved, off-site facility. Wastes may include used antifreeze and lead-acid batteries from equipment, wastewater and sludge, spent solvents, waste oils, diesel fuel, and release agents from cleaning operations. Improper collection, containment, and disposal could lead to environmental liability.

Illicit Abandonment

Illicit abandonment of unpermitted waste could occur at the cement batch plant. Illicit abandonment is the illegal dumping of pollutants on a property. It can become the property owner’s burden for cleanup and third-party bodily injury or property damage if law enforcement cannot locate the originator of the waste.

Wastewater

Wastewater could be generated from several sources, including reclaiming activity to remove returning cement from trucks and truck and equipment washing. On-site basins or tanks may be used to store wastewater for stabilization or before disposal. Failure to properly collect wastewater, malfunctions in slurry or wastewater collection equipment, contaminant or sediment-polluted water run-off, or releases from on-site storage sites could result in environmental liability.

Environmental Liability Insurance Can Provide Coverage For

On-site cleanup of new and pre-existing pollution conditions

Off-site cleanup of new and pre-existing pollution conditions

Third-party claims for bodily injury, property damage, and cleanup costs arising from on-site or off-site pollution conditions

Defense of third-party claims

Both sudden and gradual pollution conditions

Products pollution liability

First and third-party transportation pollution liability

Civil fines, penalties, and assessment (where insurable by law)

Emergency response costs for pollution incidents

Above and underground storage tank operation

Non-owned disposal sites (NODS)

Silt and sedimentation

Illicit abandonment

Loading and unloading

Natural resource damage

Claims Scenarios & Examples

Operators of a large cement plant agreed to pay a $1,505,309 fine for violations of the Clean Air Act by exceeding annual emissions for total suspended particulates and fine particulate matter, non-compliance with opacity testing, monitoring, reporting and recordkeeping requirements, and exceeding opacity limits.
A concrete batch plant was sued by a residential community that alleged dust emissions from the plant, located a quarter mile away, had migrated and contaminated their properties and caused multiple residents, including children, to develop respiratory issues. The case was settled before going to court, with the batch plant agreeing to provide monetary compensation of 6.5M for property damage, health-related expenses, and cleanup.
Two concrete mixing companies will pay $300,000 to clean-water advocacy groups in two large counties as part of a court settlement following allegations that polluted stormwater originating from their facilities made its way to local bodies of water. A joint complaint filed by two environmental groups alleged that a large concrete ready-mix company and its subsidiary violated the Clean Water Act by discharging stormwater with high pH levels and metals from its facilities. $30,000 of the settlement will be donated to a wetland and wildlife care center that rehabilitates and releases orphaned wildlife back into nature.
Following a stormwater inspection, the state environmental protection agency issued fines and ordered a concrete batch plant to test soil and groundwater. The state determined that outside chemical storage areas and industrial activities were not adequately contained, and stormwater was allowed to come in contact with these areas, potentially contaminating soil and groundwater. Following the results of the sampling, the state ordered the owner to clean up the top 5 feet of soil where the stormwater had accumulated on-site. Remediation costs totaled $115,000.
The Environmental Protection Agency (EPA) and the U.S. Department of Justice (DOJ) announced that a large cement company agreed to pay a $1.7 million penalty and invest approximately $33 million in pollution control technology to resolve alleged violations of the Clean Air Act at six of its manufacturing plants. The company also agreed to pay $745,000 to mitigate the effects of past excess emissions from its facilities.
Two concrete companies settled a lawsuit for violations of the Clean Water Act and the state’s General Industrial Stormwater Permit. The companies operated a ready-mix concrete batch facility. The lawsuit alleged that the facility discharged polluted stormwater into a ravine, which flows into a river. To mitigate past violations, the company agreed to send $30,000 to a local environmental foundation to fund environmental projects to improve water quality in local watersheds.

Final Consideration

Your business can be faced with the cost to defend itself against allegations or legal action from pollution related events, regardless if you are at fault or not. Having the proper insurance coverage in place will help fund the expenses incurred to investigate or defend against a claim or suit and provide you with environmental claims handling expertise.
