The guidelines define the following terms in addition to definitions found in 40 CFR 280.

Delivery Prohibition- prohibiting the delivery, deposit, or acceptance of product to an underground storage tank that has been determined to be ineligible by EPA or a state implementing agency for such delivery, deposit, or acceptance. (NOTE: The term “state” does not exclude local government implementing agencies.) (Grant Guidelines To States For Implementing The Delivery Prohibition Provision Of The Energy Policy Act Of 2005).

Existing – for purposes of these guidelines, existing means that an underground tank, piping, motor fuel dispensing system, facility, community water system, or potable drinking water well is in place when a new installation or replacement of an underground tank, piping, or motor fuel dispensing system begins (Grant Guidelines To States For Implementing The Secondary Containment Provision Of The Energy Policy Act Of 2005).

Green Tag - a document, device, tag, or other item identifying an underground storage tank or underground storage tank facility as eligible to receive product. Such item is generally affixed to the fill pipe or otherwise conspicuously displayed at the underground storage tank facility (Grant Guidelines To States For Implementing The Delivery Prohibition Provision Of The Energy Policy Act Of 2005)

Installation Of A New Motor Fuel Dispenser System – The installation of a new motor fuel dispenser and the equipment necessary to connect the dispenser to the underground storage tank system. It does not mean the installation of a motor fuel dispenser installed separately from the equipment needed to connect the dispenser to the underground storage tank system. For purposes of these guidelines, the equipment necessary to connect the motor fuel dispenser to the underground storage tank system may include check valves, shear valves, unburied risers or flexible connectors, or other transitional components that are beneath the dispenser and connect the dispenser to the underground piping (Grant Guidelines To States For Implementing The Secondary Containment Provision Of The Energy Policy Act Of 2005).

Motor Fuel– Petroleum or a petroleum-based substance that is motor gasoline, aviation gasoline, No. 1 or No. 2 diesel fuel, or any grade of gasohol and is typically used in the operation of a motor engine. (NOTE: This definition applies to blended petroleum motor fuels such as biodiesel and ethanol blends that contain more than a de minimis amount of petroleum or petroleum-based substance.) (Grant Guidelines To States For Implementing The Secondary Containment Provision Of The Energy Policy Act Of 2005).

Piping– For purposes of the secondary containment guidelines, piping is the hollow cylinder or the tubular conduit constructed of non-earthen materials that routinely contains and conveys regulated substances from the underground tank(s) to the dispenser(s) or other end-use equipment. Such piping includes any elbows, couplings, unions, valves, or other in-line fixtures that contain and convey regulated substances from the underground tank(s) to the dispenser(s). This definition does not include vent, vapor recovery, or fill lines (Grant Guidelines To States For Implementing The Secondary Containment Provision Of The Energy Policy Act Of 2005).

Potable Drinking Water Well– Any hole (dug, driven, drilled, or bored) that extends into the earth until it meets groundwater which (Grant Guidelines To States For Implementing The Secondary Containment Provision Of The Energy Policy Act Of 2005):

• supplies water for a non-community public water system, or
• otherwise supplies water for household use (consisting of drinking, bathing, and cooking, or other similar uses).

Such wells may provide water to entities such as a single-family residence, group of residences, businesses, schools, parks, campgrounds, and other permanent or seasonal communities.

Product Deliverer- Any person who delivers or deposits product into an

underground storage tank. This term may include major oil companies, jobbers,

petroleum transportation companies, or other product delivery entities.

Replace– This term applies to underground tanks and piping (Grant Guidelines To States For Implementing The Secondary Containment Provision Of The Energy Policy Act Of 2005):

Underground tank– Replace means to remove an existing underground tank and install a new underground tank (NOTE: A new underground tank is a tank that meets the new tank standards in 40 CFR 280.20, whether or not the tank was ever used before.) Piping– Replace means to remove and put back in an amount of piping connected to a single underground tank defined by the state to be a replacement. States may determine the amount of piping connected to a single underground tank that triggers replacement by piping length, percent of piping replaced, percent of piping replacement cost, or some combination of these. At a minimum, states must consider a piping replacement to have occurred when 100 percent of the piping, excluding connectors (such as flexible connectors), connected to a single underground tank is removed and put back in. States are encouraged to consider variations in underground storage tank system layout, such as those having extensive piping runs, when determining piping replacement criteria.

Secondary Containment– A release prevention and release detection system for an underground tank and/or piping. The release prevention part of secondary containment is an underground tank and/or piping having an inner and outer barrier. Between these two barriers is a space for monitoring. The release detection part of secondary containment is a method of monitoring the space between the inner and outer barriers for a leak or release of regulated substances from the underground tank and/or piping (called interstitial monitoring). Interstitial monitoring must meet the release detection requirements in 40 CFR 280.43(g) (Grant Guidelines To States For Implementing The Secondary Containment Provision Of The Energy Policy Act Of 2005).

Under-Dispenser Containment (UDC)– Containment underneath a dispenser that will prevent leaks from the dispenser from reaching soil or groundwater. Such containment must (Grant Guidelines To States For Implementing The Secondary Containment Provision Of The Energy Policy Act Of 2005):

• Be liquid-tight on its sides, bottom, and at any penetrations;
• Be compatible with the substance conveyed by the piping; and
• Allow for visual inspection and access to the components in the containment system and/or be monitored.

Underground Storage Tank (UST)– This term has the same meaning given to it in Section 9001 of Subtitle I, except that such term does not include tank combinations or more than a single underground pipe connected to a tank (Grant Guidelines To States For Implementing The Secondary Containment Provision Of The Energy Policy Act Of 2005).

Underground Tank – This term has the same meaning as underground storage tank except that such term does not include underground piping (Grant Guidelines To States For Implementing The Secondary Containment Provision Of The Energy Policy Act Of 2005).
