2.05.3(3)(b) <br />There were four culverts located south of and below the loadout facility which conveyed <br />surface runoff and in some cases irrigation water under the railroad tracks. The outlet ends <br />of the culverts were designated as small azea exemption sampling points (SAE-1 through <br />SAE-4). See the Sedimentation Control and Small Area Exemption Map (Map 14) for the <br />location of the culverts. Exhibit 9 provides a discussion of the SAE sampling requirements. <br />The following table presents the size of each culvert and its condition. Culverts are identified <br />by their respective SAE number. Railroad construction in 2002 eliminated culvert SAE-2. <br />Culvert Diameter Condition <br />SAE - 1 16" Good <br />SAE - Z 18" Eliminated <br />SAE - 3 24" Good <br />SAE - 4 30" Good <br />The three remaining culverts are located under the main line railroad tracks, The mainline <br />track has been in place for many years. The date the main line track and culverts were <br />constructed is not known. However, it is virtually certain the mainline track and culverts are <br />exempt from design prior requirements as set forth in Rules 2.07.6 and 4.05.3(1)(c). <br />During the fall of 1994, the operator installed a 1,500 gallon polyethylene tank for the <br />storage of a dilute antifreeze solution. The dilute antifreeze will be comprised of a mixture <br />of 55 gallons of ethylene glycol with 250 gallons of water. The dilute antifreeze will be <br />applied to stoker coal for freeze protection as the coal is loaded into rail cars. To control <br />spills, an approximate 10' X 10" concrete addition was added to the stoker oil building to <br />house the dilute antifreeze tank. <br />2.05 - 2b <br />Rev.
