2016 ANNUAL HYDROLOGY REPORTS
McClane Canyon Mine Permit No. C-1980-004
Munger Canyon Mine Permit No. C-1981-020
This report on the mine inflows, discharges and probable hydrologic
consequences is submitted in compliance with the stipulations of the Mining and
Reclamation permits for the mines noted above. The stipulations require a report
for each permit. Since the mines are in close proximity, the effects are combined.
The McClane Canyon mine remains in temporary cessation and the Munger
Canyon Mine has been reclaimed.
This report shall first discuss the effect of McClane Canyon Mine (MCM) on the
hydrologic regime, next discuss the effect of Munger Canyon Mine, and then give
an overview of the surface water system and groundwater monitoring. This report
shall conclude with a discussion of the cumulative effect of both mines on the
hydrology of East Salt Creek.
Monitoring requirements are detailed in the MCM permit in Section 4.2.3 (page
4-17 & 4-20) and on Table 4.2-15. Monitoring requirements for the Munger
Canyon Mine are detailed in Section 2.6 (page 2-29 & 30).
Monitoring for McClane Canyon and Munger Canyon Mines per the approved
permit documents for temporary cessation, (or permanent cessation in the case
of Munger as it has been reclaimed) shall include; quarterly water quality
samples from SW -1 and SW -8 for field parameters (pH, conductivity,
temperature, flow) and a full suite sample will be obtained quarterly, water quality
samples twice per year for SW-2;once during snow melt and once during a storm
event if water is available at time of water sampling, and quarterly water quality
samples for SW -3. The quantity of flow will be measured at the time when
samples are collected. GW -1, 3 and 9 will be monitored quarterly for field
parameters (pH, conductivity, temperature and static water level). And new
discharge point 004A (new sampling location in compliance with discharge
permit issued in 2015) will be monitored twice per month for pH, TSS, Iron and
Flow. Monitoring will occur when enough water is available for a sample, and
safe conditions exist for gaining access to monitoring location.
McClane Canyon Mine
Mine History and Production:
The McClane Canyon Mine began production in 1977. The mine ceased
production later that year when a fault was encountered. The mine remained idle
until 1980. From 1977 through 1982 the mine produced a total of 184,365 tons of
coal. In 1983 the mine was idled and remained under Division approved
temporary cessation until November 1988. In December of 1988, 3,995 tons of
coal was mined. In 1989; 125,200 tons of coal was produced. Production during
1990 totaled 208,945 tons. Production for 1991 totaled 194,000 tons of coal.
