We are subject to numerous federal, state and local environmental, health, safety and land use laws and regulations in the jurisdictions in which we operate, including the management, storage, transportation and disposal of chemicals and wastes; product regulation; air water and soil contamination; land use, fire code and zoning; and the investigation and cleanup of any spills or releases that may result from our management, handling, storage, sale, or transportation of chemicals and other products. The nature of our business exposes us to risks of liability under these laws and regulations. Ongoing compliance with such laws and regulations is an important consideration for us and we invest substantial capital and incur significant operating costs in our compliance efforts. In addition, societal concerns regarding the safety of chemicals in commerce and their potential impact on the environment have resulted in a growing trend towards increasing levels of product safety and environmental protection regulations and restrictions on the locations and operations of chemical facilities. These concerns have led to, and could continue to result in, more stringent regulatory intervention by governmental authorities. In addition, these concerns could influence public perceptions, impact the commercial viability of the products we sell and increase the costs to comply with increasingly complex regulations, which could have a negative impact on our business, financial condition and results of operations.
In addition, we operate a fleet of more than 350 commercial vehicles, primarily in our Water Treatment Group, which are highly regulated, including by the DOT. The DOT governs transportation matters including authorization to engage in motor carrier service, including the necessary permits to conduct our businesses, equipment operation, and safety. We are audited periodically by the DOT to ensure that we are in compliance with various safety, hours-of-service, and other rules and regulations. If we were found to be out of compliance, the DOT could severely restrict or otherwise impact our operations, which could have a material adverse effect on our operations as a whole, including our results of operations and cash flows.
If we violate applicable laws or regulations, in addition to being required to correct such violations, we could be held liable in administrative, civil or criminal proceedings for substantial fines and other sanctions that could disrupt, limit or halt our operations, which could have a material adverse effect on our operations as a whole, including our results of operations and cash flows. Liabilities associated with the investigation and cleanup of releases of hazardous substances, as well as personal injury, property damages or natural resource damages arising out of such releases of hazardous substances, may be imposed in many situations without regard to violations of laws or regulations or other fault, and may also be imposed jointly and severally (so that a responsible party may be held liable for more than its share of the losses involved, or even the entire loss). Such liabilities can be difficult to identify and the extent of any such liabilities can be difficult to predict. We use, and in the past have used, hazardous substances at many of our facilities, and have generated, and continue to generate, hazardous wastes at a number of our facilities. We have in the past been, and may in the future be, subject to claims relating to exposure to hazardous materials and the associated liabilities may be material.
