25 Pa. Code § 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.
