(a) No
person shall use any single or multiple compartment volatile organic compound
water separator which receives effluent water containing two hundred gallons
(seven hundred sixty liters) or more of any volatile organic compound a day
from any equipment that is processing, refining, treating, storing, or handling
volatile organic compounds having a Reid vapor pressure of 0.5 pounds per
square inch or greater unless such compartment is equipped with a properly
installed vapor loss control device described as follows and which is in good
working order, and in operation:
(1) A
container having all openings sealed which totally encloses the liquid content.
All gauging and sampling devices shall be gas-tight except when gauging or
sampling is taking place;
(2) A
container equipped with a floating roof, consisting of a pontoon type roof,
double deck-type roof, or internal floating cover roof, which will rest on the
surface of the liquid contents and be equipped with a closure seal or seals to
close the space between the roof edge and container wall. All gauging and
sampling devices shall be gas-tight except when gauging or sampling is taking
place;
(3) A container equipped
with a vapor recovery system consisting of a vapor gathering system capable of
collecting the volatile organic compound vapors and gases discharged, and a
vapor disposal system capable of processing such volatile organic compound
vapors and gases to prevent their emission to the atmosphere. All container
gauging and sampling devices shall be gas-tight except when gauging and
sampling is taking place; or
(4) A
container having other equipment of equal efficiency for purposes of air
pollution control may be approved by the director after demonstrating
equivalence to the director by one of the following methods:
(A) an actual emissions test in a full size
or scale sealed tank facility which accurately collects and measures all
hydrocarbon emissions associated with a given closure device, and which
accurately simulates other emission variables, such as temperature, barometric
pressure and wind. The test facility shall be subject to prior approval by the
director, or
(B) a pressure leak
test, engineering evaluation or other means where the director determines that
the same is an accurate method of determining equivalence.
(b) Compliance with Reid vapor
pressure requirements shall be determined by evaluating Reid vapor pressure
pursuant to ASTM Method D323-99 or other EPA approved methods.
