1.0 INTRODUCTION
This report summarizes measurements of Particulate Matter less than l0 microns nominal
aerodynamic diameter (PMro) collected and processed by Alton Coal Development LLC, (ACD)
from the five monitoring stations located at the Coal Hollow Mine Facility in Alton, Utah.
Monitoring for PMro is a condition of the mines operating permit.
PMro monitoring at the site consists of five BGI PQ200 PMro monitors run by solar power. Figure 2
of this report shows the approximate locations of the monitoring locations. The BGI PQ200 monitors
are EPA Reference Method monitors and are operated on the National Particulate l-in-6 Monitoring
Schedule. The data summarized herein covers the data collected during the second quarter of 2023.
2.0 SITE LOCATION
The Coal Hollow Mine is located in Kane County, Utah, approximately three miles southeast of the
town of Alton, Utah. Figure I on the following page gives an overview of the site location.
Specifically, the Coal Hollow Mine is located in Sections 7,18,19,20,29, and 30 of Township 39S,
Range 5W and Section 12 and l3 of Township 39S, Range 6W; with an approximate facility location
of:
Northing: 41401699 meters
Easting: 371534 meters
Universal Transverse Mercator (UTM) Datum NAD27, Zone 12
The three monitoring locations as depicted in Figure 2, are located in positions to collect both
background and maximum PM10 concentrations. The background monitor has a manufactures serial
#962,thercfore this monitor will be referred as monitor 962A. The compliance monitor for the Coal
Hollow Mine (CHM) has a manufactures serial #963, therefore this monitor will be referred as
monitor 9638. The co-located monitor has a manufactures serial #964, therefore this monitor will
be referred as monitor 964C. The background monitor coordinates are Northing: 4140856, Easting
373119, (UTM) Datum NAD27, Zone 12. In preparation for future mining at the South Private
Lease (SPL), the CHM compliance monitor and the co-located monitor have been relocated to the
coordinates: Northing: 4140833, Easting 371231, (UTM) Datum NAD27, Zone 12. The North
Private Lease area of the CHM is located in Sections 12, 13 of Township 39S, Range 6W and
Sections 7, 18 of Township 39S, Range 5W. The compliance monitor for the North Private Lease
has a manufactures serial #2366, therefore this monitor will be referred as monitor 2366D. The co-
located monitor has a manufactures serial #2398, therefore this monitor will be referred as monitor
23988. The NPL compliance monitor and the co-located monitor coordinates are Northing:
4141570, Easting 370928, (UTM) Datum NAD27, Zone 12.

3.0 AIR QUALITY DATA SUMMARIES
A listing of the measured PMro concentrations for the quarter are presented in Appendix B
(individual data sheets are provided on the enclosed disk in the PDF version of Appendix B)
and Field Data Sheets generated during the collection of each sample are presented in Appendix
D. Measurements were collected during a 24-hour periods and represent the average PMro
concentration during the midnight-to-midnight data collection cycle. As required by the
operating permit for the CHM, duplicate measurements were made with Sampler #9638
(designated as a compliance monitor) and Sampler #964C (designated as a co-located sampler)
to the extent possible. The quarterly mean PMro concentration and the comparison of measured
concentrations to standards are based on measurements from the primary Sampler #9638. If a
measurement from Sampler #9638 was missing or invalid, the measurement from the
secondary Sampler #964C would be used. Also, required by the operating permit for the NPL,
duplicate measurements were made with Sampler #2366D (designated as a compliance
monitor) and Sampler #2398E (designated as a co-located sampler) to the extent possible. The
quarterly mean PMro concentration and the comparison of measured concentrations to standards
are based on measurements from the primary Sampler #2366D.1f a measurement from Sampler
#2366D was missing or invalid, the measurement from the secondary Sampler #23988 would
be used.

4.2.1 Precision of PMro Measurements
The precision of the PMro measurements was determined from the duplicate samples collected
from the collocated BGI PQ200 Monitors 963B and 964C atthe Coal Hollow Mine and 2366D
and 2398E at the North Private Lease. As recommended in 40 CFR, Part 58, Appendix A,
Section 5.3.1, PMro precision checks are reported for instances when the concentrations for
duplicate samples both exceed 3 pglm3. Duplicate samples that did not meet this condition were
omitted for the purposes of the precision checks. Appendix C, of this report summarizes
precision calculations between the compliance monitor and the co-located monitor. Monthly
flow rate verification data is also summarized in Appendix C.
Precision calculations at the Coal Hollow Mine were developed based on 4 valid pairs of co-
located monitoring data during the quarter. Single point precision based on 10 CFR, Part 58,
Appendix A Equation 2 results were LI to30.9%o. The aggregate coefficient of variability (CV)
calculated in accordance with 10 CFR, Part 58, Appendix A Equation ll is22.7%. This value
is not withinthe lUYo goal for aggregate CV.
Precision calculations at the Coal Hollow Mine were developed based on 3 valid pairs of co-
located monitoring data during the quarter. Single point precision based on 40 CFR, Part 58,
Appendix A Equation 2 results were -3.4 to 4.7o/o. The aggregate coefficient of variability (CV)
calculated in accordance with 40 CFR, Part 58, Appendix A Equation I I is 9.5%. This value
is within the lUYo goal for aggregate CV.
4.2.2 Audit Results
The accuracy of the PMro sampler flows was verified by a performance audit conducted by Air
Resource Specialist on August 29,2023. A copy of the audit report is presented in Appendix E
and is summarized in Table VI. The audit results indicate that all five samplers were operating
properly.

4.2.3 Zero and Single Point Flow Rate Checks
Zero and single-point flow rate verifications were performed by a site technician at the time of
the audit. The data was then input into a statistical calculator to calculate percent difference and
bias between each of the monitors and the monthly single point flow rate measured by a NIST
traceable calibration orifice. The calculator used is called the "Data Assessment Statistical
Calculator" DASC Tool. DASC was developed for the data user community and can be found
in the Precision and Accuracy Reporting System within the Quality Assurance section of EPA's
Ambient Monitoring Technology Information System. This data is presented in Appendix C of
this report.

1.0 INTRODUCTION
Air Resource Specialists, lnc. (ARS) conducted a performance audit of Alton Coal Development,
LLC ambient air quality monitoring systems on August 29,2023. The monitoring sites are located at the
Coal Hollow Mine near Alton, Utah.

2.0 AUDIT ITiETHODS
Audit procedures, audit challenge ranges, and acceptance criteria are described below. These
ranges and limits conform to EPA's PSD guidelines. Audit results were verbally communicated to the
site operator prior to departure from the site. A follow-up e-mail summarizing audit findings was also
sent to Alton Coal Development, LLC personnel. Audit details are provided in Appendix A.
Guidance from the following EPA documents was used to establish the audit procedures:
. 40 CFR 58, Appendix B. Quality Assurance Requirements for Prevention of Significant
Deterioration (PSD) Air Monitoring
. EPA Quality Assurance Handbook for Air Pollution Measuremenf Sysfems;
- Volume l. A Field Guide to Environmental Quality Assurance
- Volume ll. Ambient Air Quality Monitoring Program
- Volume lV. Meteorological Measurements
. EPA Meteorological Monitoring Guidance for Regulatory Modeling Applications
2.1 PARTIGULATE SAMPLERS (FRirl PMro)
The filter-based FRM PMro particulate samplers are audited in their normal operating mode.
ARS audits the samplers with a BGI deltaCal audit standard which measures flow, temperature, and
barometric pressure. Prior to conducting the flow audit, a system leak check is performed in
accordance with the manufacturer's specifications. The observed volumetric operational flow and
design flow of the sampler are compared to the audit flows measured by the audit standard.
Differences between the operational sampler flow and audit flow that are greater than t10% are
considered out of tolerance. Differences between the designated design flow and the audit flow greater
than t10% are considered out of tolerance. ln addition to the flow audits, observed ambient
temperature, filter temperature, and barometric pressure measurements of the particulate samplers
are also audited by comparison to the audit standard. A temperature difference greater than t2oC and
a barometric pressure difference greater than t1Omm Hg are considered out of tolerance. Audit
methods and acceptable criteria for the particulate samplers are summarized in Table 2-1.
