Dear David:
Subject: Technical Revision 48 (TR-48).
1989 Annual Report, Appendix W, Sections 1-9
rap r Mine's Annual Report for 1989 is composed of nine distinct sections.
ec ion 1.0 reports 1989 reclamation activity as specified in Section 2.04.13
o the Colorado Mined Land Reclamation Board Regulations for Coal Mining. All
ppropriate maps are enclosed.
Se lion 2.0 is the Annual Hydrology Report and is composed of ten 'subsections.
sections 2.8 and 2.9 are proposed reductions in monitoring programs.
2.1 Climatological Data
2.2 Pit Dewatering
2.3 Mining Advancement and Ash Disposal
2.4 Monitoring Points
2.5 Hydrological Data
2.6 Hydrological Trends
2.7 Spoil Spring Sampling
2.8 Monitoring Well Abandonment
2.9 Hydrological Monitoring and Analysis Reductions
2.10 Lux Application for Water Rights
Section 3.0 is a report on Trapper's Drainageway Reconstruction efforts 1987-
89. It consi of a narrative segment describing our reconstruction methods
and results s well as a map showing the locations of our drainageway recon-
struction efforts minewide. In 1989, approximately 7,600 ft of drainage
re onst ction was performed. The map also shows diversion ditches to be left
as par of the reclaimed land surface. Peak flow data from the 10-year, 24-
h ur arshall flume located in Coyote drainage are included. Normally, as-
b t profiles for newly reconstructed drainage segments are provided to the
D ision, however, due to adverse weather conditions following completion,
t is was not completed during 1989. Drainage profiles will be completed as
weather permits and should be submitted to the Division by late spring 1990.
Based on the success of our drainage reconstruction program, Trapper proposed
to no longer provide the Division with as-built drainage profiles in future
Annual Reports.
