N.J. Admin. Code § 7:1E-2.2

Current through Register Vol. 56, No. 24, December 18, 2024

Section 7:1E-2.2 - Storage

(a) Aboveground storage tanks shall meet the following standards:

1. Aboveground storage tank installations shall be provided with secondary containment or a diversion system, designed and built pursuant to N.J.A.C. 7:1E-2.6.

2. The base underlying the storage tank shall be made of or surfaced with a material impermeable to passage or chemical attack by the stored substance under the conditions of storage prevailing within the tank. Existing storage tanks shall be exempt from this requirement until such time as they may require substantial reconstruction or replacement, or the bottom is being replaced, unless the Department orders a storage tank removed from service because of the likelihood of a discharge. Before such a tank is returned to service, it must meet this requirement.

3. Pipes leading to and from aboveground storage tanks which enter the tank below the liquid level shall be equipped with valves that can be remotely activated or are readily accessible in the event of a leak or discharge, and which are sufficiently close to the tank that they can prevent the contents of the tank from escaping outside the secondary containment area in the event of a pipe failure outside the containment area. Such pipes shall not penetrate or pass through any walls, dikes or berms used as secondary containment, unless the impermeability or integrity of the secondary containment is not impaired.

4. Aboveground storage tanks shall undergo integrity testing in accordance with N.J.A.C. 7:1E-2.16.

(b) Underground storage tanks shall meet the requirements of N.J.A.C. 7:14B.

(c) If a storage tank is served by internal heating coils, such coils, the pipes leading to and from them, and the appurtenances to which they connect, must be designed so that any leakage passing from the tank into the heating coil system will be captured and contained in a secondary containment or wastewater treatment system.

(d) Every aboveground storage tank, except as provided in (e) below, shall have a high liquid level audible or visual alarm set to activate at a predetermined level and designed to alert personnel directly responsible for the filling operation of high liquid level conditions, and one of the following:

1. A high liquid level pump cutoff device, with a level detector separate from the high liquid level detector, designed to stop flow at a predetermined level;

2. Direct communication between tank gauger and pumping station, such as direct line of sight, or telephone or radio communication; or

3. Fast response systems for determining liquid levels, which result in rapid shutdown of pumping.

(e) Owners or operators of aboveground storage tanks of 2,000 gallons or less may meet the requirement of (d) above by having such tanks attended at all times during the filling procedure.

(f) Storage tank overfill lines, or vent lines on storage tanks without overfill lines, where they exist, shall be protected by secondary containment, or directed into other tanks, or other appropriate holding areas.

(g) Mobile or portable storage tanks shall be positioned or located so as to be protected by secondary containment or diversion structures designed and built pursuant to N.J.A.C. 7:1E-2.6. Such storage tanks are subject to the requirements of N.J.A.C. 7:1E-2.9.

(h) Tote, drum, bag, and other small container storage areas shall be equipped with secondary containment or diversion systems designed and built pursuant to N.J.A.C. 7:1E-2.6.
