Current through Reg. 49, No. 28; July 12, 2024
(a) For the
					 Beaumont/Port Arthur, Dallas/Fort Worth, El Paso, and Houston/Galveston 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 paragraphs (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.
