Spring and Seep Stations <br />• During 2006, one spring was monitored semi-annually for flow and field pazameters <br />(SPJC-1). Flow data and hydrographs are included in Appendix V. Spring SPJC-1 had no <br />observed flow throughout the yeaz. <br />Conclusions <br />Coal mining operations began at Lorencito during the fourth quarter of 2001 and coal <br />extraction terminated in July 2002. The mine is currently completing final reclamation <br />activities and Phase I release has been granted for the azea of active mining. Monitoring <br />to date does not indicate any impacts to local or regional water resources from mining; <br />however, changes in water quality over the past two yeazs may be caused by increased <br />coalbed methane development in lower Lorencito Canyon and side canyon tributaries. <br />SECTION 4 -REFERENCES CITED <br />Leet, Don L., Judson, Sheldon, Kaufman, Marvin E. 1982.
