Control methods to be used for fugitive dust emissions from concrete batching plants: (List the methods to be used to control fugitive dust emissions from each of the specific activities shown below. Use the control method codes listed below, (A) through (S), to identify them. If there is to be no control of fugitive dust emissions from a particular emissions unit, please use the appropriate control method code for the selection entitled "Uncontrolled.") Fugitive Dust Emissions Units Control Method Codes Silo ID Silo Vents Weigh hopper loading of cement, sand and aggregate Weigh Hopper ID Mixer ID Loading of transit-mix truck (batching) Loading of flat-bed truck (dry-batching) Loading of wet-batch Transit truck The various control methods and their respective code letters are given in the following sections. Please complete the requested information for any control method(s) cited above.
