This site was <br />used to discharge water from remedial activities at the UST facilities area. NE -001 -G was <br />sampled at its outfall prior to discharging into ditch D -16, which flows into Pond NE007, a site <br />monitored under NPDES CO- 0000906. This site was eliminated during 1999 with reclamation <br />of the remediation systems and termination of Permit COG - 310069 was approved by CDPHE. <br />NE -004: A grab sample station of the discharge from the primary spillway of sediment <br />Pond 004. This site predominantly handles stormwater runoff from the New Elk underground <br />development waste pile. <br />NE -005: A grab sample station of the discharge from the primary spillway of sediment <br />Pond 005 which treats stormwater and industrial runoff from the area east of the trucking offices. <br />This pond was reclaimed in 2004 and the site is no longer monitored. <br />NE -006: The thickener recycling Pond 006 (prep plant process water) is a non - <br />discharging facility. <br />NE -007: A grab sample station of the discharge from the primary spillway of sediment <br />Pond 007. This site treats stormwater runoff from the East Portal of the New Elk facilities area <br />as well as handling flow from NE -033. <br />
