Section 62-296.414 - Concrete Batching PlantsThe following requirements apply to emissions units producing concrete and concrete products by batching or mixing cement and other materials. This rule also applies to facilities processing cement and other materials for the purposes of producing concrete, and to equipment used to mix cement and soil for onsite soil augmentation or stabilization.
(1) Stack Emissions. Emissions from silos, weigh hoppers (batchers), and other enclosed storage and conveying equipment shall be controlled to the extent necessary to limit visible emissions to 5 percent opacity.(2) Unconfined Emissions. The owner or operator shall take reasonable precautions to control unconfined emissions from hoppers, storage and conveying equipment, conveyor drop points, truck loading and unloading, roads, parking areas, stock piles, and yards as required by paragraph 62-296.320(4)(c), F.A.C. For concrete batching plants the following shall constitute reasonable precautions: (a) Management of roads, parking areas, stock piles, and yards, which shall include one or more of the following: 1. Paving and maintenance of roads, parking areas, and yards.2. Application of water or environmentally safe dust-suppressant chemicals when necessary to control emissions.3. Removal of particulate matter from roads and other paved areas under control of the owner or operator to mitigate reentrainment, and from building or work areas to reduce airborne particulate matter.4. Reduction of stock pile height or installation of wind breaks to mitigate wind entrainment of particulate matter from stock piles.(b) Use of spray bar, chute, or partial enclosure to mitigate emissions at the drop point to the truck.(3) Test Methods and Procedures. All emissions tests performed pursuant to the requirements of this subsection shall comply with the following requirements. (a) The reference test method for visible emissions shall be EPA Method 9, as described at 40 C.F.R., Part 60, Appendix A-4, adopted and incorporated by reference at Rule 62-204.800, F.A.C.(b) Test procedures shall conform to the procedures specified in Rule 62-297.310, F.A.C. All test results shall be reported to the Department in accordance with the provisions of Rule 62-297.310, F.A.C.(c) Visible emissions tests of silo dust collector exhaust points shall be conducted while loading the silo at a rate that is representative of the normal silo loading rate. The minimum loading rate shall be 25 tons per hour unless such rate is unachievable in practice. If emissions from the weigh hopper (batcher) operation are also controlled by the silo dust collector, the batching operation shall be in operation during the visible emissions test. The batching rate during the emissions test shall be representative of the normal batching rate and duration. Each test report shall state the actual silo loading rate during emissions testing and, if applicable, whether or not batching occurred during emissions testing.(d) If emissions from the weigh hopper (batcher) operation are controlled by a dust collector which is separate from the silo dust collector, visible emissions tests of the weigh hopper (batcher) dust collector exhaust point shall be conducted while batching at a rate that is representative of the normal batching rate and duration. Each test report shall state the actual batching rate during emissions testing.(4) Frequency of Testing. (a) The owner or operator of any concrete batching plant using an air general permit shall have a visible emissions test conducted for stack emissions referenced in subsection 62-296.414(1), F.A.C., no later than sixty (60) days after commencing initial operation, and annually thereafter.(b) The owner or operator of any concrete batching plant operating under the authority of an air construction permit or air operation permit shall have a visible emissions test conducted for stack emissions referenced in subsection 62-296.414(1), F.A.C., prior to submitting the application for an initial air operation permit, and annually thereafter.Fla.
