- Compliance: MSHA, EPA, 30 CFR 75.380, State Water Authority
Main Pump Station Equipment
Inspect main dewatering pump station per 30 CFR 75.380.
- Is total pump station capacity capable of handling maximum anticipated inflow plus 25% safety factor?
- Is at least one fully functional standby pump available in case of primary pump failure?
- Are pumps operating within normal parameters (pressure, flow rate, amps)?
- Do pumps automatically start when water level reaches preset trigger elevation?
- Are discharge lines free of blockages with check valves preventing backflow?
- Is backup power supply (generator or alternative feed) available for pump station?
Sump and Inflow Monitoring
Monitor inflows and sump conditions.
- Is sump water level within normal operating range with adequate pump-down capacity?
- Has daily inflow rate been measured and compared against historical trends for anomalies?
- Has sudden unexpected increase in inflow rate been investigated for potential water source breakthrough?
- Is sump free of excessive sediment accumulation that reduces effective storage volume?
- Is high-water alarm set and functional to warn miners of rising water before critical level reached?
Inundation Prevention and Barrier Pillars
Verify inundation safeguards per 30 CFR 75.388.
- Are barrier pillars of adequate size maintained near water hazards per 30 CFR 75.388 requirements?
- Are advance boreholes drilled per 30 CFR 75.388 before mining within 200 feet of water hazard?
- Are mine maps current showing all water bodies, old workings, and impounded water within 1,000 feet?
- If inundation occurred, can miners reach safe egress within estimated inundation time?
- Are water hazard areas clearly marked on working maps and communicated to shift supervisors?
Discharge Water Quality
Verify compliance with NPDES permit discharge limits.
- Is mine water pH tested before discharge and within NPDES permit range (typically 6.0-9.0)?
- Are total suspended solids (TSS) within NPDES permit limit (typically 35-70 mg/L)?
- Are dissolved metals (iron, manganese) within effluent limits for the receiving watershed?
- Is discharge volume metered and logged for NPDES Discharge Monitoring Report (DMR)?
- Is mine water treatment system (lime neutralization, settling) operating effectively?
