N.Y. Comp. Codes R. & Regs. tit. 6, § 613-3.2 – General operating requirements.

(1) Every facility must ensure that releases due to spilling or overfilling do not occur. One of the transfer procedures described in NFPA 385 (2012 edition) or API RP 1007 (March 2001 edition) must be used in order to comply with the requirement of this paragraph, unless those procedures are technically infeasible. In circumstances of technical infeasibility, the facility must develop and employ practices to ensure that releases due to spilling or overfilling do not occur.
(2) The facility must report, investigate, and clean up any spills and overfills in accordance with section 613-3.4(d) of this Subpart.
(3) Every category 2 or 3 UST system must have a label at the fill port specifying tank registration identification number, tank design and working capacities, and type of petroleum that is able to be stored in the UST system.
(4) Every UST system fill port must be color coded in accordance with API RP 1637. If a UST system contains petroleum that does not have a corresponding API color code, the facility must otherwise mark the fill port (for example, with stenciled letters) to identify the petroleum currently in the UST system. For any fill port connected to multiple UST systems storing different types of petroleum, the facility may place the marking near the fill port (for example, with a label or placard) to identify the types of petroleum in the UST systems.
(5) Where there are monitoring wells located at a facility, every monitoring well must be clearly identified as a monitoring well to prevent accidental delivery of petroleum to the monitoring well and must be sealed or capped so as to prevent liquid from entering the well from the surface.
(6) The facility must keep all gauges, valves, and other equipment for spill prevention in good working order.
(7) Immediately prior to a delivery, the carrier must determine that the UST has available working capacity to receive the volume of petroleum to be delivered. Every aspect of the delivery must be monitored and immediate action must be taken to stop the flow of petroleum when the working capacity of the UST has been reached or should an equipment failure or emergency occur.
(b) Operation and maintenance of corrosion protection.
Every facility having a metal UST system with corrosion protection must comply with the following requirements to ensure that releases due to corrosion are prevented until the UST system is permanently closed pursuant to section 613-3.5(b) of this Subpart:
(1) All corrosion protection systems must be operated and maintained to continuously provide corrosion protection to the metal components of that portion of the UST and piping that routinely contains petroleum and is in contact with the ground.
(2) All UST systems equipped with cathodic protection systems must be inspected for proper operation by a qualified cathodic protection tester in accordance with the following requirements:
1. (i) frequency. All cathodic protection systems must be tested at yearly intervals; and
2. (ii) inspection criteria. All cathodic protection systems must provide adequate electrical current to prevent corrosion.
(3) For UST systems using cathodic protection, records of the operation of the cathodic protection must be maintained to demonstrate compliance with the requirements of this section. The records generated to meet the provisions of paragraph (2) of this subdivision must be kept for three years.
(c) Compatibility.
Every facility must use a UST system made of or lined with materials that are compatible with the petroleum stored in the UST system.
(d) Lining repairs for steel USTs.
(1) Manufacturer’s guarantee. A steel UST may be lined under the direction of the lining manufacturer or a certified representative. The manufacturer or representative must guarantee to the owner in writing that the lining will not fail, crack, separate, or deteriorate and the tank will not leak the product specified in storage for a period of 10 years. A copy of the guarantee must be kept by the owner for the life of the tank.
(2) Structural requirements.
1. (i) A steel UST may be lined only if it meets the following structural conditions:
  1. (a) the tank has a design shell thickness of seven gauge or more;
  2. (b) the tank has a minimum metal thickness of 1/8 inch at holes after reaming;
  3. (c) the tank has no open seam or split;
  4. (d) the tank has fewer than ten holes with none larger than 1/2 inch in diameter; and
  5. (e) the tank meets all standards for structural soundness of the lining manufacturer.
2. (ii) A steel UST which fails to meet all of the requirements of subparagraph (i) of this paragraph must be permanently closed in accordance with section 613-3.5(b) of this Subpart.
3. (iii) To determine adherence to the requirements of subparagraph (i) of this paragraph, the entire interior surface of the steel UST must be tapped with a ballpeen hammer for soundness or inspected using other equivalent or superior nondestructive methods. Weak areas, holes and seams must be ballpeen hammered (before and after sandblasting) to obtain structurally sound edges. Holes and seams must be reamed until the edges of the opening are a minimum of 1/8 inch thick.
(3) Preparation of tank interior.
1. (i) Cleaning of UST prior to lining. Prior to lining, a UST must be cleaned. Wash water must not be discharged to the lands or waters of the State unless the discharge is in conformance with the standards of Parts 701, 702, 703, and 750 of this Title, as applicable.
2. (ii) Sludge removal. Sludge accumulation on the bottom of the UST must be removed, transported, and disposed of in a manner consistent with all State and Federal requirements for solid waste disposal.
3. (iii) Sandblasting of internal surfaces. The entire internal surface of the UST must be sandblasted completely free of scale, rust, and foreign matter. Following sandblasting, the entire surface must be brushed and vacuumed such that the surface when viewed without magnification is free of all moisture and foreign matter.
4. (iv) Plugging of perforations. All perforations must be tightly plugged with boiler plugs or screws made of noncorrodible plastic. Boiler plugs or screws must be covered with a laminate of resin and fiberglass cloth which overlaps all sides of the plug with a minimum of 6 inches and which has a minimum area of 144 square inches.
(4) Installation of striker plates. Prior to applying the coating material, a 10-gauge steel plate which covers a minimum of 144 square inches must be installed and centered under the fill tube and gauging tube. The plate must be bonded to the interior surface of the UST.
(5) Lining specifications.
1. (i) Any noncorrodible epoxy-based resins or equivalent coating may be used for lining a steel UST if the lining is of sufficient thickness, density, and strength to form a hard impermeable shell which will not leak, crack, wear, soften, or separate from the interior surface of the UST.
2. (ii) The lining’s coefficient of thermal expansion must be compatible with steel so that stress due to temperature changes will not be detrimental to the soundness of the coating.
3. (iii) The lining must be compatible with petroleum products and petroleum additives.
(6) Application of lining.
1. (i) The lining must be applied and cured in strict accordance with manufacturer’s specifications.
2. (ii) The lining must be applied as soon as possible but not later than eight hours after sandblasting and cleaning of the internal surface. Visible rust, moisture, or foreign material must not be present.
(7) Inspection of lining. The lining must be checked for air pockets and blisters, and electrically tested for pinholes. The lining thickness must be checked with an Elcometer Thickness Gauge or equivalent and the hardness checked with a Barcol Hardness Tester or equivalent to assure compliance with manufacturer’s specifications. Any defects must be repaired.
(8) Tank closings.
1. (i) If the UST has a manway, the manway cover gasket must be replaced with a new one before resealing.
2. (ii) If the UST does not have a manway and an opening has been cut, the UST must have a manway properly welded in place prior to beginning work or the UST must be sealed as follows:
  1. (a) a 1/4-inch thick steel cover plate, rolled to the contour of the tank exterior must be made to overlap the hole at least two inches on each side (for example, the cover plate should measure at least 26″×26″ if the opening was cut 22″×22″);
  2. (b) the cover must be used as a template to locate 3/4-inch diameter holes on five-inch centers, one inch from the edge of the cover;
  3. (c) the cover plate must be sandblasted and both sides and the entire inside surface of the plate must be covered with coating material to act as a gasket;
  4. (d) before the coating on the cover cures, the cover must be fastened to the UST using 1/2-inch minimum diameter bolts. The bolt shafts are to be placed through the holes from the inside of the tank and held in place by spring clips, then fastened with lock washers and nuts which have been dipped in a seam sealer;
  5. (e) after being bolted to the UST, the cover plate and surrounding tank surface must be properly sandblasted, coated with coating material, and allowed to cure before backfilling the hole.
(9) Tank tightness testing. Following closure of the UST and before backfilling, the relined UST must be given a tightness test in accordance with section 613-3.3(c)(1) of this Subpart.
(e) Tank systems in locations subject to flooding.
For category 1 and 2 UST systems located in an area where the UST may become buoyant because of a rise in the water table, flooding, or accumulation of water, the facility must maintain safeguards in accordance with sections 2-5.6 of NFPA 30 (1984 edition). If such safeguards include ballasting of a UST with water during flood warning periods, tank system valves and other openings must be closed and secured in a locked position in advance of the flood. Ballast water removed from the UST after the flood must not be discharged to the waters of the State unless the discharge is in conformance with the standards of Parts 701, 702, 703, and 750 of this Title, as applicable.
