INSPECTION DATE June 13. 1997 INSPECTOR'S INITIALS TAS
OBSERVATIONS
1. A site inspection of the T.H.E. Aggregate Source, Canon City Quarry was conducted in
order to evaluate the status and performance of existing stormwater controls and the status
of the new haul road construction. On April 23, 1997 the Colorado Mine Land Reclamation
Hoard approved the operator's amendment request to expand the size of the operation to 100
permitted acres, including an alternate haul road which diverts truck traffic away from
Tunnel Drive.
2. The operator indicated that the Quarry facility has received a significz~nt volume of rain
recently, 7 inches of rain during the past 10 days. The stormwater controls along the
existing haul road are nearly completed are were functioning very well. The stormwater
diversion channel routing drainage from Pond 1 to Ponds 5-7 was not constructed. Ponds 5-7
were also not constructed.
3. Construction of Pond 1 at the west edge of the processing area is nearly complete. The
operator has completed grading of the pond, application of bentonite, and application of fine
gravel. A riprapped inlet has been installed. The riprap outlet is yet ~.o be installed.
4. North of Pond 1 was evidence of a hydraulic line spill onto the processing yard surface.
Approximately 80 square feet was contaminated with hydraulic fluid. There did not seem to
be any imminent danger of a detrimental impact to surface water; however, Mr. Tezak agreed
to remove all evidence of contaminated materials and dispose of properly. The Division
considers this matter to be a problem that will require corrective actions. Please see page
3.
5. The collection channels along the haul road from the processing area down to Pond 2 need
to be "cleaned out" and also riprapped in conformance with the drainage p:Lans specified in
the recently approved permit amendment application.
6. The outlet spillway of Pond 2 has been installed. There was a small volume of runoff
water remaining in Pond 2.
7. The catchment basin immediately downgradient of Pond 2 also contained .a small volume of
runoff water. The operator has installed an adequately sized culvert to route drainage
across the haul road and into a collection channel that empties into Pond 3.
e. The collection channel that routes drainage from the haul road, across a bench area, and
into Pond 3 is badly eroded and needs to be stabilized with fill material and additional
riprap.
9. Pond 3 contained a significant volume of sediment laden runoff. Constuction of Pond 3
is completed and the pond appears to be functioning well.
10. The catchment basin opposite Pond 3 was dry. The outslopes of this basin should be
seeded with the mix specified in the site reclamation plan.
11. The collection channels along the haul road from Pond 3 to Pond 4 have :riprapped. Also,
several culverts have been installed along this stretch of the haul road t:o manage runoff.
The collection channel and culvert immediately upgradient of Pond 4 is signficantly silted
in. Approximately 50& of the capacity of these structures remains. Theref~~re, the operator
will need to clean them out prior to the next storm event. The operator a:cpressed a desire
to create a slight increase the grade of the channel in this area to facilitate drainage.
The Division encourages the operator to perform this desired change as soo~i as practicable.
12. Construction of Pond 4 has been completed. Only a small volume of water was seen in Pond
4 and the water appeared to be very clear. Therefore, the drainage system in place along the
existing haul road, although not 100$' completed, appears to be funtioning very well.
13. The operator has begun construction of the alternate haul road. Construction of the road
is nearly 50& complete. The operator estimates that construction of the road will be
completed by mid-July. There is a significant volume of fill material being generated during
the haul road construction. This material appears to be very suitable for revegetation
