United Rentals : to Acquire Neff Corporation

Environmental

United Rentals applies an environmental charge to rented equipment that contains an internal combustion engine, hydraulic oils or similar components. The charge is 1.30% of the rental charge for equipment with a maximum charge of $75. The charge is designed to recover the company's direct and indirect expenses for the handling, managing and disposing of waste products, hazardous materials and related administrative costs.

Some of our indirect expenses include, but are not limited to, the handling and managing of wastewater disposal, oil and fuel spills, fuel storage and management, fees paid to regulatory agencies and fees paid to vendors. Some of our direct environmental expenses include proper disposal of products from the care, maintenance and operation of equipment including used oil filters, spent oil absorbent, parts cleaners, scrap tires and waste antifreeze. This is not a government-mandated charge.
