For any non -criteria reportable pollutant: <br />If the emissions increase by 50% or five (5) tons per year, whichever is less, <br />above the level reported on the last APEN submitted to the Division. <br />Whenever there is a change in the owner or operator of any facility, process, or <br />activity; or <br />C. Whenever new control equipment is installed, or whenever a different type of <br />control equipment replaces an existing type of control equipment; or <br />Whenever a permit limitation must be modified; or <br />Below is a list of the source's most recent APEN submittals for each Point covered <br />by this permit: <br />AIRS Pt ID <br />Description <br />Last APEN Rec <br />Next APEN Due <br />oil <br />Conveyors and Transfer Points <br />11/24/2009 <br />10/25/2014 <br />012 <br />Coal Processing Plant — Crushers/Screens <br />11/24/2009 <br />10/25/2014 <br />013 <br />Coal Silos and Train Loadout System <br />11/24/2009 <br />10/25/2014 <br />014 <br />Coal Stockpiles <br />11/24/2009 <br />10/25/2014 <br />015 <br />Refuse Stockpiles <br />11/10/2009 <br />10/11/2014 <br />016 <br />Truck Hauling of Coal <br />11/24/2009 <br />10/25/2014 <br />019 <br />Mine Ventilation Shafts <br />11/24/2009 <br />10/25/2014 <br />020 <br />Coal Prep Plant (wash plant) <br />11/10/2009 <br />10/11/2014 <br />There have been no process modifications or changes which would require a more <br />recent submittal for the listed Points above. However, it was determined during <br />the inspection that there are several unreported Points and sources of emissions <br />above APEN-required thresholds (see `Unreported Emissions Discussion' on page <br />5 of this report). These include: <br />-One (1) pneumatically loaded rock dust silo equipped with a pulse jet baghouse to <br />control particulate matter emissions. Uncontrolled actual emissions from this <br />Point are above APEN-reporting thresholds. This unit was previously unreported <br />to the Division and had not been issued an AIRS Point Number or been <br />incorporated into the source's Permit. <br />-One (1) diesel -fired reciprocating internal combustion engine, rated at 50 hp, <br />supplying power to the emergency backup generator for the main office building <br />server. The unit was manufactured in 2009 and installed at MCC in 2010, and is <br />thus subject to NSPS Subpart Illi. As per Regulation 3, Part B, Section II.D., all <br />sources subject to a Division -adopted NSPS (including NSPS Subpart IIII) are <br />required to obtain a permit. The engine was previously unreported to the Division <br />and had not been issued an AIRS Point Number or Permit. <br />-As explained in the VOC Emissions Discussion' on page 7 of this report, using <br />the information available at the time of the inspection, it appears that MCC likely <br />has VOC emissions above APEN-reporting thresholds from multiple points at the <br />mine. VOC emissions associated with ventilation air and methane drainage wells <br />have not been previously reported to the Division. <br />Therefore, as the source had not submitted an APEN requesting modification to <br />their facility -wide permit to include these emissions sources (i.e. rock dust silo, <br />2012 Air Pollution Inspection <br />0510015-INSP-2012.docx Page 18 of 30 <br />
