I wanted to let you know that I retired as of 06.30.19 but will continue to be involved with the Charlotte, NC site as a
part-time employee to allow for a smooth transmission. Going forward your main contact will be Matt Dostal. He can
be reached at 314.835.2816.

QUALIFIERS
Project: TREX-CHARLOTTE GW
Pace Project No.: 92438460
DEFINITIONS
DF - Dilution Factor, if reported, represents the factor applied to the reported data due to dilution of the sample aliquot.
ND - Not Detected at or above adjusted reporting limit.
TNTC - Too Numerous To Count
J - Estimated concentration above the adjusted method detection limit and below the adjusted reporting limit.
MDL -Adjusted Method Detection Limit.
Pace Analytical Services, LLC
9800 Kincey Ave. Suite 100
Huntersville, NC 28078
[phone]
PQL - Practical Quantitation Limit.
RL - Reporting Limit - The lowest concentration value that meets project requirements for quantitative data with known precision and
bias for a specific analyte in a specific matrix.
8 - Surrogate
1,2-Diphenylhydrazine decomposes to and cannot be separated from Azobenzene using Method 8270. The result for each analyte is
a combined concentration.
Consistent with EPA guidelines, unrounded data are displayed and have been used to calculate % recovery and RPD values.
LCS(D) - Laboratory Control Sample (Duplicate) .
MS(D) - Matrix Spike (Duplicate)
DUP - Sample Duplicate
RPD - Relative Percent Difference
NC - Not Calculable.
SG - Silica Gel - Clean -Up
U - Indicates the compound was analyzed for, but not detected.
Acid preservation may not be appropriate for 2 Chloroethylvinyl ether.
A separate vial preserved to a pH of 4-5 is recommended in SW846 Chapter 4 for the analysis of Acrolein and Acrylonitrile by EPA
Method 8260.
N-Nitrosodiphenylamine decomposes and cannot be separated from Diphenylamine using Method 8270. The result reported for
each analyte is a combined concentration.
Pace Analytical is TNI accredited. Contact your Pace PM for the current list of accredited analytes.
TNI -The NELAC Institute.

ANALYTE QUALIFIERS
E Analyte concentration exceeded the calibration range. The reported result is estimated.
IK The recalculated concentration of the calibration standards) did not meet method acceptance criteria; this result should
be considered an estimated value.
M1 Matrix spike recovery exceeded QC limits. Batch accepted based on laboratory control sample (LCS) recovery.
R1 RPD value was outside control limits.
v1 The continuing calibration verification was above the method acceptance limit. Any detection for the analyte in the
associated samples may have a high bias.
v2 The continuing calibration verification was below the method acceptance limit. The analyte was not detected in the
associated samples and the sensitivity of the instrument was verified with a reporting limit check standard.
v3 The continuing calibration verification was below the method acceptance limit. Any detection for the analyte in the
associated samples may have low bias.

Routine Monitoring Report Review (RMRR) Checklist
Permit No.: WI0300345
Report Name: 6 Month Post Inj. GW and SW Mon Rept
Date Stamped in Received: 10/22/2019
Reviewer: MR
Date Reviewed: 3-10-20
1. BIMS: Permit Issued date: 7/21/17 . Expiration date:
6/30/22 . If Expired, check with Permittee if they want to renew. If
not will need to close out permit and send completion permit letter, and make permit
"Inactive" in BIMS.
2. For Non -Discharge (Now referred to as Injection Closed -loon GW Remediation)
permit; if they don't want to -renew, they will have to request rescission.
3. BIMS: Log report in Events Tab. Select-> `Compliance Schedule Met' and enter name
and date of report, and date we received. Also, note that a RMRR was completed and
inserted into report. Date Completed: 3/10/2020
4. BIMS: For 51/In-Situ reports- Has Injection Event Report (IER) been received and info
entered into BIMS Y (Yes, No, or N/A). If No, check file to see if
we have received and then enter into BIMS. If never received, then request from
Consultant and CC Permittee via email. After receipt of IERs from these parties enter
into BIMS.
For Non-Discharge/Closed-Loop reports- Is billing is up to date? (Yes, No,
or N/A). If past due, notify Permittee/Consultant via email, and include contact info for,

Attn: Peggie Simpson
1617 Mail Service Center

5. BIMS: Check Wells Tab and see if GW-is/GW-30s (if applicable) have been entered:
Y (Yes, No, or N/A). If No, and well status is still `proposed', then
check file to see if we have received GW-ls and then enter into BIMS. If not received,
then request from consultant and CC Permittee. After receipt from these parties, enter as -
built well construction into BIMS (change status of well from proposed to `Active'); and
well abandonment data, if applicable.
Continued On Other Side
Page 1 of 2 Rev. 3-8-2020

6. For 5I/hi-situ groundwater remediation reports- Do a quick review of report to see if
there are any obvious impacts`from injection activities by reading Summary and
Conclusions/Recommendation Section, and monitoring data tables. Compare pre -
injection levels of sulfate, iron, phosphate, etc. to post injection levels and note this
below. If there are no impacts evident, indicate `No impacts from injection evident'.
Note: The groundwater quality at the site must be monitored until concentrations
meet pre -injection levels or 2L standards before the permit can eventually be
Completed in BIMS, and a Completion Letter Sent to Permittee.
For Non -Discharge reports- Also check influent and effluent concentrations, most
permits require a minimum 95% reduction in concentrations.
NOTES/COMMENTS:
Wells continue to have elevated sulfate. P will continue to monitor. Also, PMW-IA has
increase in VOCs, iron, and sulfate; and decrease in pH.
7. When this Monitoring Report Review is complete, securely insert inside cover of
monitoring report and file. Done? Y (Y or N).
