c. On revised page 2.05-50 there is discussion of the "1 ORT water transfer pipeline". This <br />same line is labeled, in extremely minute font, on Map 16 as "1 ORT dewatering waterline". <br />Please assure the names are consistent between map and text. <br />d. On revised page 2.05-50.5 there is discussion of the "1 ORT Dewatering Well #2", while <br />elsewhere in the text and on Map 16 this structure is named "1 ORT Borehole #2. Please use <br />consistent names throughout both text and Map. <br />e. Revised page 2.05-50.5 also describes the "mine water return line" at the l ORT Borehole <br />area. None of the waterlines shown on Map 16 are labeled "mine water return line". Please <br />use consistent names throughout both text and Map. <br />f. Revised page 2.05-50.6 describes the EMD dewatering facility. Elsewhere in the text and <br />on Map 16 this area is described as the l ORT Borehole area. Please stay consistent in <br />naming designations. <br />g. Revised page 2.05-55 refers to the l ORT Dewatering Wells No.1 and 2 while elsewhere <br />these features are called l ORT Borehole 1 and 2. Please stay consistent in naming <br />designations. <br />7. Revised page 2.05-50 indicates that production mine water can discharge at the NW Mains Ventilation <br />Shaft. This vent shaft is not shown on Map 16. If the NW vent shaft is a part of the mine water <br />management process, then it needs to be shown on Map 16. If it is not a part of the mine water <br />management system, then the text should be revised. <br />8. Revised page 2.05-50 discusses that water from the Fish Creek Borehole (FCBH) and Fish Creek Vent <br />Shaft (FCVS) can be pumped eastward to FCM-2 or the Barricade Chamber. The Division <br />understands that water is piped into underground working via either of these two boreholes. This <br />portion of the text also states that Mine water can also continue eastward at this point to l ORT <br />Boreholes. A telephone conversation with Jerry Nettleton on November 7, 2008, indicates that mine <br />water would not be piped eastward from FCM-2 or the Barricade Chamber to l ORT Boreholes. Please <br />correct this description in the text. <br />9. Revised page 2.05-50.4 describes TORT Borehole #1 as having a 350 gpm pump. TCC has indicated <br />that this pump has been replaced with a 600 gpm pump. Please update this text to the current size <br />pump and remain consistent with descriptions on Map 16. <br />10. Map 16 needs to correctly show the discharge location for CPDS permit COG 850048 outfall 001. <br />The on-the-ground location varies slightly from that shown on the map. <br />11. It is not clear from Map 16 which waterlines are located on the surface and which are underground. <br />Inclusion of a Map Legend, or different shading of surface versus underground features could clarify <br />this. Please also make sure that the waterlines lengths described in the text agree with the waterline <br />lengths depicted on Map 16. <br />12. Due to the complexity of the Mine Watering System the Division believes that a concise summary of <br />TCC's Mine water handling system needs to be included in the text. The summary would use <br />consistent names that are in agreement with names shown on Map 16. The summary would also <br />clearly describe the direction of water flow, transfer points and discharge points.
