Current through Register Vol. 43, No. 39, September 26, 2024
(a) No person shall
place, store, or hold in any stationary tank, reservoir, or other container
capable of holding more than 40,000 gallons of any VOC liquid having a true
vapor pressure of one and five tenths pounds per square inch, absolute (psia)
or greater under actual storage conditions unless the tank, reservoir, or other
container is a pressure tank capable of maintaining working pressures
sufficient to prevent vapor loss to the atmosphere or is designed and equipped
with one of the following vapor loss control devices:
(1) for storage of VOC liquid having a true
vapor pressure of less than 11.1 psia at storage conditions, an internal
floating roof meeting the following requirements:
(A) it shall have a primary seal and
continuous secondary seal extending from the floating roof to the tank wall.
The primary seal shall be a liquid mounted type or when the floating roof
already has a primary seal, a metallic shoe seal will be installed to function
as a primary seal. Replacement primary seals shall be liquid mounted or
metallic shoe type; and
(B)
automatic vent openings shall be closed except when the floating roof is being
floated off or landing on the leg supports; or
(2) for storage of VOC liquid having a true
vapor pressure of equal to or greater than 11.1 psia at storage conditions, a
pressure tank sealed or vented to a vapor processing system; or
(3) a properly installed, operated and
maintained vapor processing system. The vapor processing system shall consist
of a vapor collection system capable of collecting the VOC vapors to prevent
their emission to the atmosphere. The vapor processing system shall achieve an
overall VOC emissions reduction efficiency of at least 90% by weight on a
continuous basis; or
(4) equipment
or means other than in (1) through (3) demonstrated to the satisfaction of the
department to be equal in efficiency for purposes of air pollution control.
(b) The owner or
operator shall maintain each affected storage tank so that the following
conditions prevail:
(1) no visible holes,
tears or other openings in the secondary seal or seal fabric;
(2) no visible gaps between the secondary
seal and tank wall are apparent;
(3) VOC liquid does not accumulate on the
internal floating roof; and
(4)
all tank openings shall be gas tight except when tank gauging or sampling is
taking place.
(c) This
regulation shall not apply to tanks having a storage capacity of 420,000
gallons or less and used to store produced crude oil and condensate prior to
lease custody transfer.
(d) The
owner or operator of an affected facility shall:
(1) within 16 weeks after the facility
becomes subject to the provisions of this regulation submit a control plan to
the department providing for final compliance with this regulation as
expeditiously as practicable but not later than the date prescribed by
subsection (d)(5) of this regulation;
(2) award contracts or purchase orders for
emission control equipment necessary to comply with the provisions of the
regulation within 24 weeks after the facility becomes subject to the provisions
of this regulation;
(3) initiate
construction or installation of the required emission control equipment within
48 weeks after the facility becomes subject to the provisions of this
regulation.
(4) complete the
construction or installation of the required emission control equipment within
100 weeks after the facility becomes subject to the provisions of this
regulation;
(5) demonstrate
compliance with this regulation within two years after the facility becomes
subject to the provisions of this regulation.
(e) The owner or operator of each affected
storage tank shall visually inspect the internal floating roof, the primary
seal and secondary seal each time the storage tank is emptied and degassed. The
owner or operator shall then conduct any repairs necessary to comply with
(b)(1) through (b)(3) before refilling the storage tank.
(f) The owner or operator of each affected
storage tank shall maintain records on a monthly basis for two years from the
date of record at the facility available for department inspection for:
(1) amount and type of VOC liquids
stored/turned over;
(2) inspection
dates with the corresponding findings;
(3) date and description of repairs of each
storage tank and floating roof or vapor processing system; and
(4) the average temperature on a monthly
basis of the stored VOC liquids.
(g) The provisions of this regulation shall
be applicable only to VOC liquid storage tanks operated at facilities subject
to the provisions of either K.A.R. 28-19-64, 28-19-67 or 28-19-68.
