(a) The Department shall specify in the NJPDES-DGW permit the relevant point of compliance at which the ground water protection standard of 7:14A-10.6 applies and at which monitoring shall be conducted. The relevant point of compliance is a vertical surface located at the hydraulically downgradient limit of the hazardous waste facility unit (unit) that extends down into the uppermost aquifer underlying the hazardous waste facility unit(s).

(b) The hazardous waste management unit is the limit projected in the horizontal plane of the area on which hazardous waste shall be placed during the active life of a hazardous waste facility unit.

1. The hazardous waste management unit includes horizontal space taken up by any liner, dike, or other barrier designed to contain hazardous waste in a hazardous waste facility unit.

2. If the facility contains more than one hazardous waste facility unit, the hazardous waste management unit is described by an imaginary line circumscribing the several hazardous waste facility units.

(c) Unless otherwise determined by the Department, the relevant point of compliance specified shall be no more than 150 meters from the hazardous waste management unit boundary and shall be located on land owned by the owner of the hazardous waste facility. In determining the relevant point of compliance, the Department shall consider the following factors:

1. The hydrogeologic characteristics of the facility and the surrounding land;

2. The volume and physical and chemical characteristics of the leachate;

3. The quantity, quality and direction of flow of ground water;

4. The proximity and withdrawal rate of the ground water users;

5. The availability of alternative drinking water supplies; and

6. The existing quality of the ground water, including other sources of contamination and their cumulative impacts on the ground water, and whether the ground water is currently used or reasonably expected to be used for drinking water.
