(1) Organic Material Storage Tanks. No person who owns, leases, operates or controls a storage tank with a capacity equal to or greater than 40,000 gallons, into which organic material having a vapor pressure of 1.5 pounds per square inch absolute or greater under actual storage conditions, is placed, stored, or held shall store, hold or otherwise transfer the organic material in the storage tank unless:
(a) each tank is equipped with a
submerged fill pipe; and,
(b) each
tank not equipped with an external floating roof (see 310 CMR
7.24(1)(c)) is equipped with one of the following control devices
1. a pressure tank system which maintains
pressure at all times so as to prevent organic material loss to the atmosphere
or,
2. a vapor recovery system
which collects all of the organic vapors emitted from the tank, and a vapor
control system which reduces emissions of vapors to the atmosphere by at least
95% over every three hour period; or
3. if the tank does not store organic
material with a true vapor pressure greater than 11.0 psia under actual storage
conditions, then a fixed roof and a floating roof consisting of a pontoon
double deck, or internal floating roof which rests on the surface of the liquid
contents and is equipped with a closure seal, or seals, to close the space
between the roof edge and tank wall, and tank gauging and sampling devices
which are gas tight except when in use; or,
4. any other equipment equal to or greater in
efficiency than listed in 310 CMR 7.24(1)(b)2. and approved by the Department
and EPA; and
(c) on or
after November 1, 1984, each external floating roof tank is equipped with an
external floating roof of a pontoon, double deck, or external floating cover
design, which rests on the surface of the liquid contents; and is fitted with a
primary seal and a continuous secondary seal which seals the space between the
edge of the floating roof and the tank wall; and stores organic material which
has a vapor pressure less than 11.0 pounds per square inch absolute under
actual storage conditions; and all tank gauging or sampling devices are gas
tight except when in use; and,
(d)
each of the seal(s) required by 310 CMR 7.24(1)(b)3. and 310 CMR 7.24(1)(c)
meet the following requirements, where applicable
1. there are no visible holes, tears, or
other openings in the seal(s) or seal fabric; and,
2. the seal(s) is intact and uniformly in
place around the circumference of the floating roof between the floating roof
and the tank wall; and,
3. for
vapor mounted primary seals on any external floating roof tank, the accumulated
area of gaps between the secondary seal and the tank wall which exceed 0.32 cm
(1/8 in.) in width do not exceed 21.2 square cm per meter of tank diameter (1.0
square in per ft of tank diameter), as determined by 310 CMR 7.24(1)(k)
and
4. measurement of the gap in
the secondary seal is made annually, and such measurement complies with 310 CMR
7.24(1)(d)3.; and,
5. a visual
inspection of the secondary closure seal is conducted semi-annually;
and,
6. an inspection of internal
floating roofs is conducted through the roof hatches monthly; and,
7. an inspection of cover and seal for
internal floating roofs is conducted whenever the tank is emptied for
nonoperational reasons or once every ten years whichever is sooner;
and,
(e) all openings in
a floating roof, except for automatic bleeder vents, rim space vents, and leg
sleeves, are:1. equipped with covers, seals,
or lids which are kept closed except when the openings are in actual use;
and,
2. equipped with projections
into tank which remain below-the-liquid surface at all times; and
(f) automatic bleeder vents are
kept closed except when the roof is being floated off of, or being landed on,
the roof leg supports; and,
(g) rim
vents are set to open when the roof is being floated off the leg supports, or
at the manufacture recommended setting; and,
(h) emergency roof drains are provided with
slotted membrane fabric covers or equivalent covers which cover at least 90% of
the area of the opening; and,
(i)
Recordkeeping and Reporting, for any tank with a
capacity of 40,000 gallons or more which contains an organic liquid with a true
vapor pressure greater than 1.5 psia, records are prepared, maintained and kept
onsite for a minimum of two years: of the average monthly storage temperature;
of the true vapor pressure, monthly throughput and type of organic material
stored; of any inspections or tests conducted under 310 CMR 7.24(1)(d)4.
through 7.; of any transfers made; and of any maintenance of the vapor
processing system; and,
(j) for any
tank with a capacity in excess of 40,000 gallons which is equipped with an
external floating roof and which contains any organic material with a vapor
pressure greater than 1.0 psia but less than 1.5 psia under actual storage
conditions, records are maintained and kept for a minimum of two years; of the
average monthly storage temperature and the type of liquid stored and its vapor
pressure; and
(k) the total area of
gaps under 310 CMR 7.24(1)(d)3. is determined by physically measuring the
length and width of all gaps around the entire circumference of the secondary
seal in each place where a 1/8 in. uniform diameter probe passes freely
(without forcing or binding against the seal) between the seal and the tank
wall, and summing the area of the individual gaps; any person who proposes to
conduct this test shall notify the Department at least 30 days before the test
so the Department may, at its option, observe the test.
(1) 310 CMR 7.24(1)(a) through 310 CMR
7.24(1)(k) do not apply to petroleum liquid storage tanks which are used to
store waxy, heavy pour crude oil, or which have a capacity less than 416,000
gallons and are used to store produced crude oil and condensate prior to lease
custody transfer.
(2) Bulk Terminals and Bulk Plants.
(a) U Bulk Terminals No person who owns,
leases, operates or controls a bulk terminal shall cause, suffer, allow or
permit the transfer into a tank truck, trailer or other contrivance of any

rack at the bulk terminal is equipped with a vapor collection and disposal

with the operating instructions of the manufacturer; and,
2. any vapor discharged during transfer of
the organic material is collected and disposed of by the vapor collection and
disposal system; and,
