30 TAC 106 - Subchapter O Oil and Gas
106.351 Salt Water Disposal (Petroleum) (Previously SE65)106.352 Oil and Gas Production Facilities (Previously SE66)
106.353 Temporary Oil and Gas Facilities (Previously SE67)
106.354 Iron Sponge Gas Treating Unit (Previously SE79)
106.355 Metering, Purging and Maintenance of Pipelines (Previously SE100)
106.351 Salt Water Disposal (Petroleum) (Previously SE 65) Salt water disposal facilities used to handle aqueous liquid wastes from petroleum production operations and water injection facilities are exempt, provided that the following conditions of this section are met. (1) Any facility processing salt water which emits a sour gas 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 or operator of the facility or the owner of the property upon which the facility is located. (2) Any open storage of salt water shall be operated in such a manner as to prevent the occurrence of a nuisance condition off-property. (3) All plant roads and truck loading and unloading areas must be operated and/or maintained as necessary to prevent dust emissions from the property which would cause or contribute to a nuisance condition. Appropriate operating activities may include reduction of speed of vehicles, use of alternate routes, and covering of dust-producing loads being hauled. Appropriate maintenance activities may include watering, treatment with dust suppressant chemicals, oiling, paving, and cleaning dust-producing surfaces. 106.352 Oil and Gas Production Facilities (Previously SE 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 and other gas conditioning facilities, including sulfur recovery units at facilities conditioning produced gas containing less than two long tons per day of sulfur compounds as sulfur are exempt, provided that the following conditions of this section are met. This section applies only to those facilities named which handle gases and liquids associated with the production, conditioning, processing, and pipeline transfer of fluids found in geologic formations beneath the earth's surface. (1) Compressors and flares shall meet the requirements of 106.512 and 106.492 of this title (relating to Stationary Engines and Turbines (Previously SE 6) and Flares (Previously SE 80)). (2) 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 section shall not exceed 25 tons per year (tpy) each of sulfur dioxide (SO2), all other sulfur compounds combined, or all volatile organic compounds (VOC) combined; and 250 tpy each of nitrogen oxide and carbon monoxide. Emissions of VOC and sulfur compounds other than SO2 must include gas lost by equilibrium flash as well as gas lost by conventional evaporation. (3) Any facility handling sour gas 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 or operator of the facility or the owner of the property upon which the facility is located. (4) 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, except in no case shall the height be less than 20 feet:
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 |
