SOURCE COMPLIANCE HISTORY <br />2012 — Division inspection determined source to be in violation for failing to submit APENs and obtain permits <br />for the rock dust silo (had been present for many years) and NSPS Subpart IIII engines (no longer a requirement if <br />emissions are below reporting thresholds). The source was also determined to be in violation for failing to operate <br />in a manner consistent with good air pollution control practices for minimizing emissions, as visible emissions <br />were observed from an improperly installed baghouse access door during rock dust silo loading. These issues <br />were corrected following the inspection. All violations were included in Case #2013-126 and were settled with the <br />2015 Inspection AIT <br />0510015-INSP-2015 Page 6 of 37 <br />Sylvester Gulch: Joy model 120-65-880, 1500 hp (exhaust) <br />Shaft #1 — fan #1: TLT Babcock model GAF 30-15-1, 2500 hp (intake) <br />Shaft #2 — fan #1: TLT Babcock model GAF 30-15-1, 2500 hp (intake) <br />Shaft #2 — fan #2: TLT Babcock model GAF 30-15-1, 2500 hp (intake) <br />Shaft #3 — fan #1: Joy model MF -65, 1500 hp (intake — not currently operated) <br />Ventilation fans are uncontrolled. Shaft #2 fans are restricted to one (1) fan operating <br />at any time. <br />Coal Prep Plant Process Equipment: <br />One (1) Conn -Weld, 8X16 Negative Slope, vibrating screen with SN: 1010014, <br />rated at 800 tph. <br />One (1) Crusher- MMD Group of Companies Series 500 (scalping station) with SN: <br />S1541058 <br />Screen #1: Bivitech, KRL/DD `B" 2400X90x, SN: 2418 & 2419 <br />020 <br />09GUI382 <br />Screen #2: (2) Conn -Weld 8X16 Horizontal, SN: H 10 10008 & H 10 10009 <br />Screen #3: Conn -Weld, 12X20 Horizontal DD, SN: H 10 100 10 <br />Screen #4: Conn -Weld, 8X16 Horizontal, SN: H1010011 <br />Screen #5: Conn -Weld, 4X10 Negative Slope, SN: D 10 100 12 <br />Screen #6: Conn -Weld, 4X10 Negative Slope, SN: D 10 100 13 <br />Crusher: McClanahan Black Diamond Crusher, SN: 20102003 <br />All processes are enclosed.

This emergency generator provides backup power to the Shaft #2 fan <br />such that miners will receive adequate ventilation air during an electrical failure at <br />the mine. MCC submitted a cancellation notice on 10/26/2015 for the small generator <br />associated with this point that is used to power the fan during startup to prevent <br />stalling. <br />022 <br />13GUI462 <br />One (1) pneumatically loaded rock dust silo equipped with a pulse jet baghouse to <br />control particulate matter emissions. <br />One (1) diesel fueled reciprocating internal combustion engine, rated at 50 hp, <br />supplying power to the emergency backup generator for the main office building <br />023 <br />13GUI463 <br />server. The unit was manufactured in 2009 and installed at MCC in 2010, and is thus <br />subject to NSPS Subpart IIII.
