Springs and Seeps The spring and seep monitoring program samples flow and water chemistry on springs • within aone- mile radius of the underground workings once annually during the late summer of the yeaz, to ensure that geohydrologic changes associated with the mine do not diminish the water quantity or quality of springs. Four springs aze monitored annually during August (Appendix C). Ponds and Direct Discharges All sediment ponds and direct dischazge points are permitted under NPDES Permits CO- 0000906. Sampling stations for these permits are described below. MDNE-1: NE-001 was a grab sample station from the New Elk Mine water discharge pipe located on the Purgatoire River for NPDES Dischazge Permit CO-0000906. The station was established to monitor the quality and quantity of mine water dischazge from the New Elk Mine. During the third quarter of 1989, the mine was sealed and the dischazge of mine inflow water was discontinued. NE-001-G: NE-001-G is a site under NPDES Permit No. COG-310069. This site is used to discharge water from remedial activities at the UST facilities azea. NE-00 1-G is sampled at its outfall prior to dischazging into ditch D-16, which flows into Pond NE- 007, aaite monitored under NPDES CO-0000906. This site was eliminated during 1999 with reclamation of the remediation system and termination of Permit COG-31 0069 as approved by CDPHE. • NE-004: A grab sample station of the discharge from the primary spillway of sediment pond 004. This site predominantly handles stormwater runoff from the New Elk underground development waste pile. NE-0O5: A grab sample station of the dischazge from the primary spillway of sediment pond 005 which treats stormwater and industrial runoff from the azea east of the trucking offices. This pond was reclaimed in 2003 and is no longer monitored. NE-006: The thickener recycling pond 006 (Prep Plant process water) is a non- dischazge facility. NE-007: A grab sample station of the discharge from the primary spillway of sediment pond 007. This site treats stormwater runoff from the East Portal of the New Elk facilities area as well as handling runoff from NE-OOIG andNE-033. NE-008: A grab sample location at the primary spillway outfall of sediment pond 008 located at the base of the Refuse Disposal Area of the New Elk Mine. NE-009: A grab sample station of the New Elk Mine water dischazge pipe located in Apache Canyon. The station was established to monitor the quality of mine water dischazge from the New Elk Mine; the mine has been inactive and sealed since 1989 with • no dischazge occurring at this site.
