116 | 117 | 118 | 119 | 120 | 121 116. Automobile restoration facilities, provided the following conditions are met: (a) All automobile body/chassis abrasive blast cleaning and coating operations shall be performed in a closed building or enclosure; or the facility shall be located a minimum of 300 feet from any recreational area or residence not occupied or used solely by the owner of the facility or the owner of the property upon which the facility is located, except that structures occupied by security or watch personnel may be located contiguously. (b) Total abrasive usage shall be less than 100 pounds per hour, 500 pounds per day, and five tons per year. (c) Total cleaning or paint usage, including solvents used for any cleaning and/or thinning purposes, shall be less than five gallons per day and 100 gallons per year. (d) The owner or operator of the facility shall maintain daily and annual records of the usage of all abrasives and coating materials used at the facility, and these records shall be made available at the request of personnel from the Texas Natural Resource Conservation Commission or any local air pollution control program having jurisdiction. These records shall be organized such that the compliance status of this standard exemption can be readily determined. 117. Any specialty wet batch, concrete, mortar, grout mixing, or pre-cast concrete products plant that operates according to the following conditions: (a) Plant capacity shall not exceed 30 cubic yards per hour with mixer size not to exceed 2.5 cubic yards. (b) All stockpiles are sprinkled with water and/or chemicals as necessary to achieve maximum control of dust emissions. (c) Dust emissions at the batch mixer feed shall be controlled by a water spray device which eliminates visible emissions, or a pickup device delivering air to a fabric filter with automatic air cleaning and a 7.0 feet per minute (ft/min) maximum filtering velocity, or automatic sequenced mechanical cleaning and a 5.25 ft/min maximum filtering velocity, or the entire mixing operation is conducted inside the enclosed process building such that no visible emissions from the building occur during mixing activities, or the batch mixer feed is enclosed such that no visible emissions occur. (d) Fabric filter(s) with a maximum filtering velocity of 4.0 ft/min with an acceptable method of cleaning shall be installed on each storage silo or the silo is vented to the control collection system. (e) A visible and/or audible warning mechanism shall be installed on each silo for warning operators that the silo is full, so that it will not be overloaded at any time. (f) All permanent in-plant roads (batch truck and material delivery truck roads) are oiled or paved and cleaned as necessary to achieve maximum control of dust emissions. Other areas on the property subject to vehicle traffic shall be oiled or sprinkled with water as necessary to achieve maximum control of dust emissions. (g) The transfer of cement from the storage silo(s) shall be handled through closed conveying systems with no visible fugitive emissions. (h) The cement weigh hopper shall be vented to a control device which eliminates visible emissions, or shall be vented inside the batch mixer. (i) Good housekeeping measures shall be maintained at all times. (j) Before construction of the facility begins, written site approval is received from the Executive Director of the Texas natural Resource Conservation Commission (TNRCC) and the facility shall be registered with the TNRCC Office of Air Quality in Austin using Form PI-7, including a current Table 20. (k) 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 30 TAC Section 116.10(a)(3) and (4) and (b), has been published and documentation thereof has been provided to the TNRCC. 118. Facilities, or physical or operational changes to a facility, provided that all of the following conditions are satisfied: (a) This exemption shall not be used to authorize construction or any change to a facility specifically authorized in another standard exemption, but not meeting the requirements of that exemption. However, once the requirements of a specific exemption are met, Exemption 118(c) and (d) may be used to qualify the use of other chemicals at the facility. (b) Emission points associated with the facilities or changes shall be located at least 100 feet from any off-plant receptor*. (c) New or increased emissions, including fugitives, of chemicals shall not be emitted in a quantity greater than five tons per year nor in a quantity greater than E as determined using the equation E = L/K and the following table.D, Feet | K |
