Surface water quantity and quality will be monitored upstream and downstream of <br /> the disturbance in McClane Canyon and on East Salt Creek upstream and <br /> downstream of the confluence of McClane Canyon and East Salt Creek in a manner <br /> approved by the Division. The monitoring plan was submitted under 2.05.6(3)(b)(iv), <br /> and includes the following, pursuant to 4.05.13(2). <br /> SW-1 and SW-8 (East Salt Creek upstream and downstream): Quarterly flow and <br /> quality. <br /> SW-2 (McClane Creek below mine bench): Flow and quality, once during spring <br /> snowmelt, and once during storm event runoff. <br /> SW-5 (McClane Creek above mine bench): Water quality samples twice a year, <br /> once during spring snowmelt, and once during storm event runoff. <br /> The water quality monitoring parameter list is outlined on Table 4.2-15 of the PAP. <br /> A reduced parameter list(Short Suite for Temporary Cessation) is included in the <br /> table. A notation on the table specifies that the short suite is to be implemented only <br /> after mining has ceased for a period of at least 6 months. <br /> Monitoring results and evaluation are submitted in an annual hydrologic report <br /> (AHR). The AHR will assess observed impacts to the surface water system, and will <br /> be structured around the normal "water year" (October 1 through September 30). <br /> The annual report will also include baseline water quality data in addition to the <br /> quarterly monitoring data to allow for comparison of baseline and"during mining" <br /> conditions. The annual report for the previous water year will be submitted no later <br /> than March 31 of each year. <br /> E. Probable Hydrologic Consequences <br /> A determination of the probable hydrologic consequences (PHC) of the mining and <br /> reclamation activities at the McClane Canyon Mine site has been made by the <br /> applicant and is found in Section 2.4.2.1 and Appendix N of the permit application. <br /> Annual PHC updates are included in the annual hydrology report submitted each <br /> year by the operator. <br /> The Probable Hydrologic Consequences section of this document is divided into two <br /> main subsections: Ground Water Effects and Surface Water Effects. <br /> Ground Water Effects <br /> The occurrence of ground water within and adjacent to the permit area is controlled <br /> primarily by the combination of local topography, stratigraphy and geologic <br /> structure. Drilling has indicated that the Cameo coal seam becomes increasingly <br /> saturated downdip (northeast) from its outcrop along the side slopes of the East Salt <br /> Creek Drainage basin. This is depicted on Figure 4.2-3, of Volume II of the permit <br /> xviii <br />
