§ 78a.64. Secondary containment around oil and condensate tanks.
(a) If an owner or operator uses a tank or tanks with a combined capacity of at least 1,320 gallons to contain oil or condensate produced from a well, the owner or operator shall construct and maintain a dike or other method of secondary containment which satisfies the requirements under 40 CFR Part 112 (relating to oil pollution prevention) around the tank or tanks which will prevent the tank contents from entering waters of the Commonwealth.
(b) The secondary containment provided by the dikes or other method of secondary containment must have containment capacity sufficient to hold the volume of the largest single tank, plus a reasonable allowance for precipitation based on local weather conditions and facility operation.
(c) Prior to drainage of accumulated precipitation from secondary containment, the secondary containment shall be inspected and accumulations of oil picked up and returned to the tank or disposed of in accordance with approved methods.
(d) After complying with subsection (c), drainage of secondary containment is acceptable if:
(1) The accumulation in the secondary containment consists of only precipitation directly to the secondary containment and drainage will not cause a harmful discharge or result in a sheen.
(2) The secondary containment drain valve is opened and resealed, or other drainage procedure, as applicable, is conducted under responsible supervision.
(e) An owner or operator who installed a tank or tanks with a combined capacity of at least 1,320 gallons prior to October 8, 2016, to store condensate produced from a well shall meet the requirements of this section when a tank is replaced, refurbished or repaired or by October 9, 2018, whichever is sooner.
