(9) "Public groundwater supply source" means a primary source of water supply for a public water system which is directly drawn from a well, underground stream, underground reservoir, underground mine, or other primary sources of water supplies which are found underneath the surface of the state.

(10) "Public surface water supply source" means a primary source of water supply for a public water system which is directly drawn from rivers, streams, lakes, ponds, impoundments, or other primary sources of water supplies which are found on the surface of the state.

(11) "Public surface water influenced groundwater supply source" means a source of water supply for a public water system which is directly drawn from an underground well, underground river or stream, underground reservoir, or underground mine, and the quantity and quality of the water in that underground supply source is heavily influenced, directly or indirectly, by the quantity and quality of surface water in the immediate area.

(12) "Public water system" means:

(A) Any water supply or system which regularly supplies or offers to supply water for human consumption through pipes or other constructed conveyances, if serving at least an average of 25 individuals per day for at least 60 days per year, or which has at least 15 service connections, and shall include:

F. R. §§ 355, 372, 302, and 68 in a concentration of one percent or greater, regardless of the AST"s location, except ASTs containing petroleum are not level 1 regulated tanks based solely upon containing constituents recorded on the CERCLA lists; or

(C) An AST with a capacity of 50,000 gallons or more, regardless of its contents or location.

(14) "Regulated level 2 aboveground storage tank" or "level 2 regulated tank" means an AST that is located within a zone of peripheral concern that is not a level 1 regulated tank.

(15) "Regulated aboveground storage tank" or "regulated tank" means an AST that meets the definition of a level 1 or level 2 regulated tank.

(16) "Release" means any spilling, leaking, emitting, discharging, escaping, or leaching of fluids from an aboveground storage tank into the waters of the state or escaping from secondary containment.

(17) "Secondary containment" means a safeguard applied to one or more aboveground storage tanks that prevents the discharge into the waters of the state of the entire capacity of the largest single tank and sufficient freeboard to contain precipitation. In order to qualify as secondary containment, the barrier and containment field must be sufficiently impervious to contain fluids in the event of a release, and may include double-walled tanks, dikes, containment curbs, pits, or drainage trench enclosures that safely confine the release from a tank in a facility catchment basin or holding pond. Earthen dikes and similar containment structures must be designed and constructed to contain, for a minimum of 72 hours, fluid that escapes from a tank.

(18) "Secretary" means the Secretary of the Department of Environmental Protection, or his or her designee.

(19) "Source water protection area" for a public groundwater supply source is the area within an aquifer that supplies water to a public water supply well within a five-year time of travel and is determined by the mathematical calculation of the locations from which a drop of water placed at the edge of the protection area would theoretically take five years to reach the well.

(20) "Zone of critical concern" for a public surface water supply source and for a public surface water influenced groundwater supply source is a corridor along streams within a watershed that warrants detailed scrutiny due to its proximity to the surface water intake and the intake"s susceptibility to potential contaminants within that corridor. The zone of critical concern is determined using a mathematical model that accounts for stream flows, gradient and area topography. The length of the zone of critical concern is based on a five-hour time of travel of water in the streams to the intake. The width of the zone of critical concern is 1,000 feet measured horizontally from each bank of the principal stream and 500 feet measured horizontally from each bank of the tributaries draining into the principal stream.

(21) "Zone of peripheral concern" for a public surface water supply source and for a public surface water influenced groundwater supply source is a corridor along streams within a watershed that warrants scrutiny due to its proximity to the surface water intake and the intake"s susceptibility to potential contaminants within that corridor. The zone of peripheral concern is determined using a mathematical model that accounts for stream flows, gradient, and area topography. The length of the zone of peripheral concern is based on an additional five-hour time of travel of water in the streams beyond the perimeter of the zone of critical concern, which creates a protection zone of 10 hours above the water intake. The width of the zone of peripheral concern is 1,000 feet measured horizontally from each bank of the principal stream and 500 feet measured horizontally from each bank of the tributaries draining into the principal stream.
