Since the reclaimed area value was greater than the standard, Alternative Test B is passed for 2018 and <br /> 2019 data. <br /> Regarding Alternative Test C, the similarity index between the lifeform species density values for the <br /> prescribed lifeforms for the BRB-5 and the Mean Species density (area-weighted)in the five reference <br /> areas is 73% (Table J-3), exceeding 90% of the standard (0.9 x 70% = 63%). <br /> 2018 similarity index is 86%, which exceeds 63% <br /> 2019 similarity index is 87%, which exceeds 63% <br /> Hence Alternative Test C is passed for 2018 and 2019 data. <br /> Regarding Alternative Test D,the total number of native species encountered in an adequate number of <br /> samples of the BRB-5 (based on allowable all-hit herbaceous cover and species density) compared to the <br /> area weighted native species standard (based on the extended reference area) (Table J-4) <br /> 2018 The total number of native species encountered in the first sixteen 100m2 samples was 56. <br /> 2018 The total number of native species encountered in the first fourteen 100m2 samples was 56. <br /> 2018 Area weighted native species density standard was 26.7 species per 100 m2. <br /> 2019 The total number of native species encountered in the first fourteen 100m2 samples was 62. <br /> 2019 The total number of native species encountered in the first seven 100m2 samples was 44. <br /> 2019 Area weighted native species density standard was 25.2 species per 100m2. <br /> Hence Alternative Test D is passed for 2018 and 2019 data. <br /> In summary, Mandatory Test A was passed as were Alternative Tests B, C and D. Thus, the species <br /> diversity test as a whole is passed for the 2018 and 2019 BRB-5 and revegetation success for species <br /> diversity for Phase III is demonstrated. <br /> PHASE III HYDROLOGY <br /> A. Basic Standards Interim Narrative Standard for Ground Water(CWQCC Regulation <br /> 41.5(c)(6). <br /> The Groundwater Point of Compliance (GWPOC) for the Seneca II West Mine was established in 2009 <br /> under Technical Revision 63 (TR-63). The GWPOC well at the Seneca II West Mine is monitoring well <br /> DCAL-02 which is screened within the Dry Creek Alluvium downgradient (north) of the mines permit <br /> boundary(see Map 1). A GWPOC for the Sage Creek Alluvium was deemed unnecessary due to the small <br /> portion of the ridgeline mined within the Sage Creek watershed. The bedrock within the permit area dips <br /> to the west and the spoil water generated at the ridge top drains to the west along the dipping bedrock, <br /> away from the Sage Creek tributaries. GWPOC bedrock wells were also deemed unnecessary due to the <br /> limited potential for the mine to negatively impact the quality of bedrock groundwater. The Wadge and <br /> Wolf Creek Coal exhibit low hydraulic conductivity (3.5E-8 to 3.5E-5 cm/sec) and attenuation and <br /> 15 <br />
