Underground Storage Tank: A tank and any underground piping connected to the tank that has 10% or more of its volume (including pipe volume) beneath the surface of the ground. USTs are designed to hold gasoline, other petroleum products, and hazardous materials.
Universal Waste Handler: Generally speaking, anyone who produces, stores, collects, or accumulates universal waste such as mercury-containing lamps, but does not treat, recycle, or dispose of them.
Universal Waste Transporter: One who engages in the process of transporting waste lamps for 10 days or less. A transporter may not store, accumulate, dispose, dilute or treat universal waste lamps. No EPA ID is required. Proper marking and labeling of waste lamps is required.
Universal Wastes: Several widely generated hazardous wastes identified by EPA that are subject to streamlined requirements for collection, storage and processing if they are recycled under the Universal Waste Rule. Batteries, certain pesticides, thermostats and mercury-containing lamps have been designated as universal wastes under the federal rule. The goal of the rule is to encourage recycling of these universal wastes rather than disposal.
