Abandoned An underground or aboveground petroleum storage tank that the current tank owner/operator or current property owner did not install, has never operated or leased to another for operation, and had no reason to know was present on the site at the time of site acquisition.
Alternative Motor fuel that combines petroleum-based fuel products with renewable fuels.
Alternative Fuel Motor fuel that combines petroleum-based fuel products with renewable fuels
ASTs All aboveground storage tanks at a facility, all the connected piping and ancillary equipment, all loading facilities, and all containment systems, if applicable
Atmospheric Tanks A storage tank that has been designed to operate at pressures from atmospheric through a gauge pressure of 1.0 psi measured at the top of the tank.
Cathodically Protected Cathodic protection (CP) is a method of controlling the corrosion of a metal structure by making it the cathode of an electrochemical cell. The simplest method connects a metal structure that is to be protected to a more easily corroded "sacrificial metal," which will serve as the anode of the electrochemical cell. Once connected in an electrically continuous path, the sacrificial metal corrodes rather than the metal structure being protected.
Compatible "Compatible" means the ability of two or more substances to maintain their respective physical and chemical properties upon contact with one another for the design life of the tank system under conditions likely to be encountered.
Composite tanks Steel USTs with a factory applied non-metallic cladding/lamination bonded directly to the tank STI ACT-100
Documentation Waste manifests, bills of lading, invoices, etc.
Due Diligence An environmental site assessment may help you discover contamination before you own the site. Reviewing the existing tank system's compliance records will help you understand the site's history.
eRAP electronic reimbursement application
Inerting Removing the volatile component of a tank interior or otherwise making the tank safe for removal.
Jacketed Tanks Steel USTs with an interstitial separation between the tank and non-metallic outer layer STI Permatank
Management Representation Letter The letter that confirms the Auditee provided the Fund Auditor with access and full disclosure of all significant facts; the Fund Auditor will send a copy of the letter to the Auditee’s organization when the audit is scheduled.
Orphaned Underground Storage Tank An owned or operated by an unidentified owner as defined in this article; or (b) No longer in use and was not closed in accordance with the procedures required by this article and the property has changed ownership prior to December 22, 1988, and such property is no longer used to dispense fuels.
Person A “person” is an individual, trust, firm, joint-stock company, federal agency, corporation, state, municipality, commission, political subdivision of a state, or any interstate body. "Person" also includes a consortium, a joint venture, a commercial entity
Pre-engineered cathodic protection systems Suitably-coated steel USTs with factory-attached sacrificial anodes) STI-P3
Property Owners A person having a legal or equitable interest in real or personal property that is subject to this article
Qualifying A facility with an aggregate aboveground storage capacity of 1,320 gallons or greater.
Reason to Know includes by personal knowledge or observation, representations by the seller or any other person, environmental assessments, reports, or any other means that there had ever been a release of petroleum product on this site.
Regulated Substances Regulated substance (UST Systems): (1) Any substance defined in section 101 (14) of the federal "Comprehensive Environmental Response, Compensation, and Liability Act of 1980", as amended, but not including any substance regulated as a hazardous waste under subtitle (C) of Title II of the federal "Resource Conservation and Recovery Act of 1976", as amended. (2) Petroleum, including crude oil or any fraction thereof that is liquid at standard conditions of temperature and pressure (60 degrees Fahrenheit and 14.7 pounds per square inch absolute). (3) Alternative fuel (4) Renewable fuel Regulated substance (AST Systems): (1) All gasoline, aviation gasoline, diesel, aviation turbine fuel, jet fuel, fuel oil, biodiesel, biodiesel blends, kerosene, all alcohol blended fuels, gas or gaseous compounds, and other volatile, flammable, or combustible liquids, produced, compounded, and offered for sale or used for the purpose of generating heat, light, or power in internal combustion engines or fuel cells, for cleaning or for any other similar usage. (2) Alternative fuel (3) Renewable fuel.
Remediation Reducing the environmental footprint of a petroleum release to soil, groundwater, surface water and air in order to be protective of human health and the environment.
Renewable Fuel Motor vehicle fuel that is produced from plant or animal products or wastes, as opposed to fossil fuel sources.
Renewable fuels A motor vehicle fuel that is produced from plant or animal products or wastes, as opposed to fossil fuel sources.
Repair to restore to proper operating condition a tank, pipe, spill prevention equipment, overfill prevention equipment, corrosion protection equipment, release detection equipment or other system component that has caused a release of product from an AST or UST system or has failed to function properly
Replaced "Replace" means to remove and put back in any amount of piping connected to a UST system.
Replacement This term applies to underground storage tanks and piping. For underground storage tanks – Replace means to remove an existing underground storage tank and install a new underground storage tank. For underground piping – Replace means to remove and put back in any amount of piping connected to a tank system. The secondary containment requirements for replaced piping are triggered when a minimum of 50% or 50 feet (whichever is less) of the total length of piping connected to a single tank is replaced. The total length of piping connected to a single tank includes the length piping from that tank to the farthest connected dispenser, including piping runs between dispensers connected to that tank.
Sensitive Environment   A type of designation for an agricultural area that needs special protection because of its landscape, wildlife or historical value.
Suspected Indirect evidence of a release such as a failed line or tank tightness test, unusual operating conditions, water in the tanks if the tanks do not test liquid-tight, inventory loss identified by leak detection equipment, inconclusive or failed SIR results or fuel in secondary containment (in contact with penetration points) or in damaged spill buckets. Suspected releases must be addressed by a system test or site check.
Temporary Closure A period of time that a storage tank is empty but is not permanently closed or has not changed service to store a non-regulated substance. This term does not apply when a tank system is emptied for repair.
Total Length The total length of piping connected to a single underground tank includes the length piping from that tank to the farthest connected dispenser, including piping runs between dispensers connected to that tank.
Underground Storage Tank(UST) Any one or combination of tanks, including underground pipes connected thereto, except those exempted in statute and these regulations, that is used to contain an accumulation of regulated substances and the volume of which, including the volume of underground pipes connected thereto, is ten percent or more beneath the surface of the ground and is not permanently closed
Upgrade the addition or retrofit of some systems (such as cathodic protection, lining, modification of the system piping, or spill and overfill controls, etc.) to improve the ability of an UST or AST system to prevent the release of product
Working Days Monday through Friday, excluding state and federal holidays.
