Introduction of members: Carol Campbell, EPA, Pete Davenport, Hydro-Geologist, Gary
Nelson, Dave Suhr’s replacement, Jim Heron-Bruce Stover’s replacement.Commodore
Update (Bruce Stover)-Site showing on Sept 19, had seven firms looking at it. They
will recon. flume and will put in sewer pipe. Bids will open on 10/17. Hope to have it
done by Dec. 31. There will be a phase 2 to re-line the pipe. Money is coming from the
Office of Surface Mines. The money is raised from tax on coal sold in the state. Bruce
said they would come up with the flume to put in there. Glen will contact Steve Baer, And
Division of Water Resources.
Donation to Mining Museum- USGS was doing filtering in August and using the
museum. Glen suggested the WCRC make a donation to show appreciation for the use of it.
Motion to donate $100 made by Larry Bussey Second made by Phil Bethke, Motion Carried.
May High Flow Data, Quick Overview- Flow is up in East Willow, Zinc levels were
almost half of prior study. Dilution doesn’t seem to make since. West Willow levels
are still high. First glance says that with higher water the concentrations were not
worse. The conclusion would be that if during high flow there is a dilution, your water is
coming from other sources. Flow sources are different during low flow than high flow. Low
flow study was done after a high water year and high flow study was done after a drought.
However, results were consistent enough to call it a high flow. Don’t need to do
another synoptic characterization to determine ? Studies would indicate that during
episodic events there is a lot of flow off of the tailings. When data is collected we can
talk about how to proceed with the report. We should include data on the observations of
the two labs.
Airport Corner Update- On Sept 17 Army Corps of Engineers brought in the XRF
machine. A map was available that showed that. The area is identified as being
contaminated. The XRF Machine only indicates lead, so samples taken will be used to return
other concentration levels. Once the report comes back, they will need to talk with CDPHE
and property owners in order to come up with the best way to provide a fix that would
insure safety of residents. At this point they will determine the intended use and then
work on a way to implement the fix. The lab has 30 samples for verification and 3 samples
that need to have TCLP. The cost will be $1900. Additional samples will be between
$200-$300. Motion to spend up to $2500was made by JB Alexander and Seconded by Phil
Bethke. Motion carried. If results come back prior to next meeting, they can move ahead
without coming to committee.
Underground Recon- Fresh water was found in the Solomon could easily cut the
amount of flow that needs to be treated. Could we go from 20 gallons a minute to 5? It
would be easier to treat what is coming out, which would make the passive filter a
possibility. Not much moving in the Commodore, some water coming out of rib at maybe 3-4
gallons per minute. All of the water that is running is going into a hole in the ground.
Going from Commodore to lower levels is maybe 5-10 gallons a minute. Since September the
water has dropped about 15 ft. but we still have 500 gallons a minute coming out of the
Nelson.
Phase one is the recon of underground sampling. Mine Safety people will be looking at
the mine and Jim Heron will go through to be sure it is ready and safe for their workers.
From this we can develop the approach, equipment and testing supplies needed.
Phase 2 would be to execute this written plan.
This will finish up the plan to do water characterization.
Memorandum of agreement between CDMG- Phase One requires $8600. This needs to be
approved by committee. Motion made by Chuck Barnes and seconded Phil Bethke. Discussion.
Motion Carried. There has to be written permission from landowners before the work can
begin. Zeke will contact Poxons. 319 money can be used to purchase to purchase enough
equipment to outfit 3 people and 1 oxygen meter. Motion to approve $3,000 made by JB
Alexander and seconded by Phil Bethke.
Section 319 Grant Report- September 19, 2000 Zeke and Glen traveled to Denver to
make a presentation to the grant committee. Kathleen said they were recommended for
funding.
