Section 780.21(b) Continued. <br />mine plan area, this problem can be dismissed at the outset. An <br />exhaustive analysis of surface water, ground water, cola, overburden and <br />topsoil has demonstrated that na toxic, acid-or alkaline-producing <br />materials exist within the mine plan area or tipple area. Detailed <br />discussions of the analyses conducted are presented under Section 179.16 <br />(surface water), Section 779.15 (ground water), Section 779.14 <br />(overburden and coal), and Section 779.21 (topsoil). <br />Based on analysis of water quality data collected by the applicant, the <br />only potential surface water quality problems are with TSS and, to a very <br />small degree, salt loading. The alkaline nature of the water present in <br />the general area largely prevents dissolution of manganese and iron. <br />Furthermore, no toxicity or excessive alkalinity or acidity has been <br />found to occur as a result of the existing Marr Mine operation. See the <br />detailed description of surface water quality presented under Section <br />719.16. Specific data on surface water chemistry are presented in Table <br />. 14, Kerr Mine Area Surface Water Quality Data, Table 13, USGS Canadian <br />River Water Quality Data, and Table 10, Kerr Tipple Area Mater Quality <br />Data. <br />Methods of Protection and Mitioation. <br />Kerr Coal intends to utilize numerous, widespread and varied methods <br />reflecting the best technology currently available to protect surface <br />water quality and quantity in the Kerr Mine Area and adjacent areas, as <br />well as the Kerr Tipple Area. These measures will include the remedial <br />measures described below. <br />Stream Buffer Zones. <br />Significant protection of surface water quality will be achieved through <br />the identification and marking of stream buffer zones and, with the few <br />exceptions discussed under Section 816.57, by not disturbing any area <br />within the stream buffer zones, and by not diverting any intermittent or <br />perennial streams in the mine plan or tipple areas. Stream buffer zones, <br />"~ as described in Section 816.57, <br />780-92R Revised - August, 1991 <br />
