Spring, Seep and Mine Dlscharge Survey <br />• Panorama Resource Services, Inc. conducted a reconnaissance level <br />survey of springs, seeps and mine discharges within one mile of <br />the permit area. Work preliminary to the field investigation <br />included a review of aerial photos provided by the operator. <br />The photos, at a scale of 1:24,000, did not provide sufficient <br />detail to aid the survey other than to disclose the locations of <br />ponds. <br />The locations of known springs, seeps and mine discharges were <br />determined from USGS topgraphic maps, the operator, and Mr. Leo <br />Montoya a local resident. The locations of these sources are <br />shown on Exhlblt AA. Flows, field quality data, and other <br />information requested by MLRD, cross-referenced to the exhibit, <br />are presented in Table 4. Laboratory analyses were performed on <br />the Engleville HSne Dlscharge (EMD), # 3 of Exhibit AA and Table <br />4. <br />Drainages within one mile of the permit were searched to <br />determine If groundwater sources were feeding the streams. No <br />additional springs, etc. were located. This does not preclude <br />the possibility that Isolated springs or seeps emerge on side <br />slopes of Insufficient volume to feed area streams. If such <br />exist, their contribution to surface flow is minimal. <br />Montova Seems. Location # 1 <br />. This seep, Ezhiblt AA, emerges from slighlty above the geologic <br />contact of the Vermejo Formation and Trinidad Sandstone. The <br />lithology at the point of emergence is a shaley zone within the <br />Vermejo Formation. When examined in April, 1988 the 'flow' <br />consisted of drips. Given the marshy vegetation adjoining the <br />site, !t may meet the definition of a 'spring' during the Spring <br />of the year. In May, the site was examined during moderate to <br />heavy rainfall, however, the flow did not appear to have changed. <br />Oxandaburu Sorina/Mine Dlscharae. Location # 2 <br />Th(s site. Exhlblt AA, shown as two springs on the USGS <br />topographic map, is actually two points of mine water discharge <br />from the Lower Starkville Seam. The Upper and Lower Starkville <br />Seams coalesced eastward to form the Engleville Seam. Given the <br />westerly dip, the Upper Starkville Seam at the point of discharge <br />!s down dip of the Engleville Seam at the Rimrock minesite. <br />The proximity and occurrence of the two sites, and their distance <br />from the Rimrock permit area, is such that they are considered as <br />a single source. During the site visit in April the flow from a <br />pipe was 5.5 gal/minute with a conductivity of 4500 umhos/cm and <br />a ph of 6.9. <br />L J <br />-6- <br />
