We are subject to a variety of federal, state and local laws and regulations relating to environmental, health and safety matters. In particular, in the United States, products containing pesticides generally must be registered with the U.S. Environmental Protection Agency, or EPA, and similar state agencies before they can be sold or applied. The pesticides we use are manufactured by independent third parties and are evaluated by the EPA as part of its ongoing exposure risk assessment and may be subject to similar evaluation by similar state agencies. The EPA, or similar state agencies, may decide that a pesticide we use will be limited or will not be re-registered for use in the United States. We cannot predict the outcome or the severity of the effect of the EPA's, or a similar state agency's, continuing evaluations. The failure to obtain or the cancellation of any such registration, or the partial or complete ban of such pesticides, could have an adverse effect on our business, the severity of which would depend on the products involved, whether other products could be substituted and whether our competitors were similarly affected.
The use of certain pesticides, herbicides and fertilizer products is also regulated by various federal, state and local environmental and public health and safety agencies. These regulations may require that only certified or professional users apply the product or that certain products only be used on certain types of locations. These laws may also require users to post notices on properties at which products have been or will be applied, notification to individuals in the vicinity that products will be applied in the future, or labeling of certain products or may restrict or ban the use of certain products. We can give no assurance that we can prevent violations of these or other regulations from occurring. Even if we are able to comply with all such regulations and obtain all necessary registrations and licenses, we cannot assure you that the pesticides, herbicides, fertilizers or other products we apply, or the manner in which we apply them, will not be alleged to cause injury to the environment, to people or to animals, or that such products will not be restricted or banned in certain circumstances. For example, we could be named in or subject to personal injury claims stemming from alleged environmental torts, similar to those that have been brought against certain manufacturers of herbicides. The costs of compliance, consequences of non-compliance, remediation costs and liabilities, unfavorable public perceptions of such products or products liability lawsuits could have a material adverse effect on our reputation, business, financial position, results of operations and cash flows.
In addition, federal, state and local agencies regulate the use, storage, treatment, disposal, handling and management of hazardous substances and wastes, emissions or discharges from our facilities or vehicles and the investigation and clean-up of contaminated sites, including our sites, customer sites and third-party sites to which we send wastes. We could incur significant costs and liabilities, including investigation and clean-up costs, fines, penalties and civil or criminal sanctions for non-compliance and claims by third parties for property and natural resource damage and personal injury under these laws and regulations. If there is a significant change in the facts or circumstances surrounding the assumptions upon which we operate, or if we are found to violate, or be liable under, applicable environmental and public health and safety laws and regulations, it could have a material adverse effect on future environmental capital expenditures and other environmental expenses and on our reputation, business, financial position, results of operations and cash flows. In addition, potentially significant expenditures could be required to comply with environmental laws and regulations, including requirements that may be adopted or imposed in the future.
