PCE Migration and Groundwater Contamination
Improper storage and handling of PCE and other dry-cleaning solvents can lead to releases that reach the subsurface soil and groundwater or stormwater systems. Contamination from the dry-cleaning site can migrate to adjacent residential or commercial properties, drinking water sources, and natural resources. Significant cleanup costs, third-party bodily injury and property damage claims, and natural resource damage claims can result.
Leaks and Spills
Leaks can occur from solvent storage containers, dry cleaning machines and equipment, underground or aboveground storage tanks, associated hoses, valves, and piping. Spills can occur from loading machines with PCE or other dry-cleaning chemicals, during loading/unloading of solvent from a delivery truck into a storage tank or from a delivery drum into the equipment, and from overfilling storage tanks or equipment.
Secondary Containment Deficiencies
Insufficient or no secondary containment of storage tanks, equipment, wastewater treatment units, solvent storage, and hazardous waste storage containers can lead to the release of chemicals. Secondary containment must be constructed of leakproof materials impermeable to solvent and cleaning fluids and capable of containing 110% of the largest possible spill.
Loading, Unloading and Transit
Leaks or spills during the loading, unloading, or transporting solvents, chemicals, or wastes sent for disposal can result in environmental liability. Hazardous waste must be labeled, contained, and transported by a licensed and permitted waste hauler. The dry cleaner could become liable for cleanup and third-party claims resulting from a spill during loading, unloading, or transporting dry cleaning chemicals or wastes if the transporter is not properly insured.
Hazardous Waste Management
Hazardous wastes produced by dry cleaning facilities include spent solvent, separator water, cooked powder residues, still bottom residues, spent cartridges, cartridge filters, button/lint trap wastes, and wash water from in-house cleaning of filters. Hazardous wastes are subject to federal and state regulations, and improper storage, labeling, or disposal could result in environmental cleanup and tort liability against the waste generator.
Wastewater
Wastewater generated by dry cleaners may include separator water, vacuum water, boiler blowdown, and wash water. Wastewater leaks or spills can occur from dry cleaning equipment, disposal storage containers, and on-site wastewater treatment units. Dry cleaners may be subject to state and local regulations regarding the discharging and disposal of wastewater. Discharging wastewater containing dry cleaning chemicals into sinks, floor drains, septic systems, and sewer systems can contaminate soil and groundwater. PCE and other chlorinated solvents are denser than water, can settle in sewer lines, and leak through joints and cracks. Due to chlorinated solvents being volatile, they can easily turn from a liquid to a vapor and penetrate the sewer wall. Wastewater containing cleaning solvents or synthetic detergents that enter surface waters can also cause natural resource damage.
Solvents
PCE and other chlorinated solvents are heavier than water and can sink deep into the groundwater and soil, and contamination can persist for a long time. Chlorinated solvents do not easily degrade, are highly volatile, and can travel considerable distances. Even relatively small amounts of these chemicals can cause significant contamination effects. Chlorinated solvents can also cause health risks, such as skin, eye, and respiratory irritation, headaches, dizziness, damage to kidneys and liver, and cancer. Petroleum-based solvents and other dry-cleaning chemicals are less toxic but can still negatively impact the environment.
Air Emissions
Air emissions may occur related to releases of solvent vapors into the atmosphere during the transfer of clothes from the washer to the dryer and the venting of the dryer exhaust airstream. Fugitive emissions may also occur from leaks around machine door gaskets, evaporation from spent filters, solvent spills, open containers, and losses during solvent transfer. Chlorinated solvent and petroleum-based solvent contamination beneath a building can also be a source of vapor intrusion into the building. Air emissions and vapor intrusion can impact indoor air conditions within the dry-cleaning space and adjacent properties or building tenant spaces, resulting in health hazards and third-party bodily injury claims.
