62. Confined feeding operations which satisfy the following conditions:

(a) Livestock animal feedlots designed to feed less than 1000 animals.
(b) Ranged turkey feeding operations, caged egg laying operations and caged pullet operations designed to feed less than 20,000 birds when a dry manure handling and storage system is used.
(c) All housed broiler, pullet, turkey, breeder hen and egg laying operations when wood shavings or similar material is used as litter.
(d) All caged egg laying and caged pullet operations designed to feed more than 20,000 hens when a dry manure storage and handling system is used and when located at least 1/4 mile from any recreational area or residence or other structure not occupied or used solely by the owner of the egg laying or caged pullet operation. Before construction of the caged laying and caged pullet operations begins, written site approval shall be received from the Executive Director of the Texas Air Control Board and the facility shall be registered with appropriate Regional Office using Form PI-7.

65. Liquid injection facilities used for underground injection of aqueous liquid wastes from petroleum production operations or for enhanced oil recovery operations, provided that the following conditions are met:

(a) For any facility processing salt water which emits a sour gas, the facility shall be located at least 1/4 mile from any recreational area or residence or other structure not occupied or used solely by the owner of the facility or the owner of the property upon which the facility is located.
(b) Any open storage of injection liquids shall be operated in such a manner to minimize detectable odors off-property.
(c) All plant roads and truck loading and unloading areas must be watered or paved and cleaned as necessary.
(d) The grounds are kept free from collection of standing pools of oil.
(e) All spills of oil shall be cleaned up immediately.

66. Any oil or gas production facility, carbon dioxide separation facility, or oil or gas pipeline facility consisting of one or more tanks, separators, dehydration units, free water knockouts, gunbarrels, heater treaters, natural gas liquids recovery units, or gas sweetening or other gas conditioning facilities, including sulfur recovery units at facilities conditioning produced gas containing less than two long tons of sulfur per day, provided that the following conditions are met:

(a) Compressors and flares shall meet the requirements of Standard Exemptions 6 and 80, respectively.

(b) Total emissions, including process fugitives, combustion unit stacks, separator, or other process vents, tank vents, and loading emissions from all such facilities constructed at a site under this exemption shall not exceed 25 tons per year (tpy) each of sulfur dioxide, all other sulfur compounds combined, all volatile organic compounds combined; and 250 tpy each of nitrogen oxides and carbon monoxide.

(c) For any facility processing sour gas, the facility shall be located at least 1/4 mile from any recreational area or residence or other structure not occupied or used solely by the owner of the facility or the owner of the property upon which the facility is located.

(d) Total emissions of sulfur compounds, excluding sulfur oxides, from all vents shall not exceed 4.0 pounds per hour (lb/hr) and the height of each vent emitting sulfur compounds shall meet the following requirements:

Total as Hydrogen Sulfide, lb/hr Minimum vent height, feet
0.27 20
0.60 30
1.94 50
3.00 60
4.00 68

Note: Other values may be interpolated.

(e) Before operation begins, facilities processing sour gas shall be registered with the appropriate Regional Office using Form PI-7 along with supporting documentation that all requirements of this exemption will be met. For facilities constructed under Standard Exemption 67, the registration is required before operation under Standard Exemption 66 can begin. If the facilities cannot meet Standard Exemption 66, a permit is required prior to continuing operation of the facilities.

67. Temporary separators, tanks, meters, and fluid handling equipment used for a period not to exceed thirty (30) operating days, beginning the first day of production through the operation of temporary facilities for the purpose of testing the content of a subsurface stratum believed to contain oil or gas; provided that all the following conditions are satisfied:

(a) Any sour gas produced during this test period shall be burned in a flare which meets the requirements of conditions (a), (b), (c), (e) and (f) of Standard Exemption 80.
(b) Total emissions of any air contaminant shall not exceed 25 tons during the test period.
(c) Operation of the facilities authorized by this exemption after the testing has been completed shall not be allowed unless such facilities are otherwise authorized according to the requirements of 116.1.

68. Reserved

69. Replacement or addition of cotton gin stands when no other equipment change or additions are involved.

70. Repairs or maintenance not involving structural changes where no new or permanent facilities are installed.

71. Any permanently or temporarily located concrete plant that accomplishes wet batching, dry batching or central mixing and operates according to the following conditions:

(a) All stockpiles are sprinkled with water and/or chemicals as necessary to achieve maximum control of dust emissions.
(b) A mechanism is installed on each bulk storage silo for warning operators that the silo is full, so it will not be overloaded at any time.
(c) All permanent in-plant roads (batch truck and material delivery truck roads) are paved and cleaned as necessary to achieve the maximum control of dust emissions. Other areas on the property subject to vehicle traffic shall be watered as necessary to achieve maximum control dust emissions.
(d) The cement weigh hopper is vented to its own fabric filter or the central collection system specified in condition (6).
(e) All bulk storage silos shall be equipped with fabric filter(s) having a maximum filtering velocity of 4.0 ft/min with mechanical shaking or 7.0 ft/min with automatic air cleaning or are vented to the central collection system specified in condition (f).
(f) The dust emissions at the batch drop point (drum feed for central mix plants) are controlled by a shroud or other pickup device delivering a minimum of 4,000 acfm of air to a fabric filter with automatic air cleaning and a 7.0 ft/min maximum filtering velocity or automatic sequenced mechanical cleaning and a 5.25 ft/min maximum filtering velocity.
(g) All open-bodied vehicles transporting material from a dry batch plant to the paving mixer(s) shall be loaded with a final layer of wet sand and/or the truck shall be covered with a tarp to control the emissions of dust to the minimum level possible under existing conditions.
(h) Unless the plant is to be located temporarily in the right-of-way of a public works project, public notice and opportunity for public hearing, as specified in 116.7(b)(2) and (3), has been published and documentation thereof has been provided to the Texas Air Control Board (TACB).
