| (a) For the Beaumont-Port Arthur, Bexar County, Dallas-Fort
Worth, El Paso, and Houston-Galveston-Brazoria areas, no person shall
use any single or multiple compartment volatile organic compound (VOC)
water separator which separates materials containing VOC obtained
from any equipment which is processing, refining, treating, storing,
or handling VOC, unless each compartment is controlled in one of the
following ways:
(1) the compartment totally encloses the liquid contents
and has all openings (such as roof seals and access doors) sealed
such that the separator can hold a vacuum or pressure without emissions
to the atmosphere, except through a pressure relief valve. All gauging
and sampling devices shall be vapor-tight except during gauging or
sampling. The pressure relief valve must be designed to open only
as necessary to allow proper operation, and must be set at the maximum
possible pressure necessary for proper operation, but such that the
valve will not vent continuously;
(2) the compartment is equipped with a floating roof
or internal floating cover which will rest on the surface of the contents
and be equipped with a closure seal or seals to close the space between
the roof edge and tank wall. All gauging and sampling devices shall
be vapor-tight except during gauging or sampling;
(3) the compartment is equipped with a vapor recovery
system which satisfies the provisions of §115.131(a) of this
title (relating to Emission Specifications);
(4) any water separator that becomes subject to the
provisions of paragraph (1), (2), or (3) of this subsection by exceeding
provisions of §115.137(a) of this title (relating to Exemptions)
will remain subject to the provisions of this subsection, even if
throughput or emissions later fall below the exemption limits unless
and until emissions are reduced to no more than the controlled emissions
level existing before implementation of the project by which throughput
or emission rate was reduced to less than the applicable exemption
limits in §115.137(a) of this title; and
(A) the project by which throughput or emission rate
was reduced is authorized by any permit or permit amendment or standard
permit or permit by rule required by Chapter 116 or Chapter 106 of
this title (relating to Control of Air Pollution by Permits for New
Construction or Modification; and Permits by Rule). If a permit by
rule is available for the project, compliance with this subsection
must be maintained for 30 days after the filing of documentation of
compliance with that permit by rule; or
(B) if authorization by permit, permit amendment, standard
permit, or permit by rule is not required for the project, the owner/operator
has given the executive director 30 days' notice of the project in
writing.
(b) For Gregg, Nueces, and Victoria Counties, no person
shall use any single or multiple compartment VOC water separator which
separates materials containing VOC obtained from any equipment which
is processing, refining, treating, storing, or handling VOC, unless
each compartment is controlled in one of the following ways:
(1) the compartment totally encloses the liquid contents
and has all openings (such as roof seals and access doors) sealed
such that the separator can hold a vacuum or pressure without emissions
to the atmosphere, except through a pressure relief valve. All gauging
and sampling devices shall be vapor-tight except during gauging or
sampling. The pressure relief valve must be designed to open only
as necessary to allow proper operation, and must be set at the maximum
possible pressure necessary for proper operation, but such that the
valve will not vent continuously;
(2) the compartment is equipped with a floating roof
or internal floating cover which will rest on the surface of the contents
and be equipped with a closure seal or seals to close the space between
the roof or cover edge and tank wall. All gauging and sampling devices
shall be vapor-tight, except during gauging or sampling;
(3) the compartment is equipped with a vapor recovery
system which satisfies the provisions of §115.131(b) of this
title.
(c) For Aransas, Bexar, Calhoun, Matagorda, San Patricio,
and Travis Counties, no person shall use any single or multiple compartment
VOC water separator which separates materials containing VOC obtained
from any equipment which is processing, refining, treating, storing,
or handling VOC, unless each compartment is controlled in one of the
following ways. The control requirements of this subsection no longer
apply for sources located in Bexar County beginning January 1, 2025.
(1) The compartment totally encloses the liquid contents
and has all openings (such as roof seals and access doors) sealed
such that the separator can hold a vacuum or pressure without emissions
to the atmosphere, except through a pressure relief valve. All gauging
and sampling devices shall be vapor-tight except during gauging or
sampling. The pressure relief valve must be designed to open only
as necessary to allow proper operation, and must be set at the maximum
possible pressure necessary for proper operation, but such that the
valve will not vent continuously.
(2) The compartment is equipped with a floating roof
or internal floating cover which will rest on the surface of the contents
and be equipped with a closure seal or seals to close the space between
the roof or cover edge and tank wall. All gauging and sampling devices
shall be vapor-tight except during gauging or sampling.
(3) The compartment is equipped with a vapor recovery
system which satisfies the provisions of §115.131(c) of this
title.
