Subject: 3rd

Quarter audits for 2018

Dear Ms. Walshe-Langford:

This report contains the results of performance audits conducted by personnel from Tennessee’s Air Quality Assurance program. The audits were conducted on August 22

nd, 23

rd, an 24

th, 2018. The audits were conducted on all gaseous and particulate monitors

located throughout the Metropolitan Davidson County area. The sites visited were East Health Center, Lockeland Elementary School and the Near Road Site off of Elm Hill Boulevard. All particulate monitors passed critical criteria and were within audit guidelines. The NO2 monitor at East was experiencing major flow problems and was not audited. The CO monitor at Near Road did not pass the zero and Level 2 audit challenges. The voltage on the Mother Board was noted to be fluctuating widely. The monitor was scheduled to be replaced.

General audit procedures are set forth in 40CFR58 (Code of Federal Regulations). Appendix A, Section 3.1.2.1 of this CFR contains a chart which shows the audit levels for which ozone, SO2, CO, and NO2 monitors may be evaluated. Appendix A also contains the requirements for auditing particulate samplers. The continuous gaseous monitors were audited with an Environics 6103 calibrator certified against an NIST (National Institute of Science and Technology) flow standard and a certified Level 2 ozone standard. The particulate monitors were audited with an NIST traceable flow system.

All continuous monitors were audited Through the Probe and all sample lines and filters.

The following points were observed and addressed during the audits:

1. For the Near Road NO2 monitor the monitor responses to the NO inputs are shown on the audit form as a comparison because the NO response usually mirrors the NO2 response.

2. The NO monitor at East had previously shown flow issues with the capillaries. An on-site test the previous day had shown an error of -34%. A one point check with my calibrator at .390 ppm resulted in a response of .273 ppm, or -30%. No further auditing was attempted. Ongoing repairs of the monitor were in progress.

3. The CO monitor at Near Road has had a history of the zero readily drifting. The change during the audit was from .040 ppm to .090 ppm. This response exceeded the allowable of .031 ppm for a zero value. The monitor also exceeded the allowable response for a Level 2 audit as defined in 40CFR58, Appendix A. A check of the main voltages on the front panel of the monitor revealed the Mother Board exhibiting a very unstable voltage pattern. A recommendation to exchange the monitor for a new one was made and accepted at the time of the audit.

Any questions concerning these audits may be directed to this office at (615) 687-7045 or to: [email protected].

Sincerely,

Radford L. Strong Environmental Specialist TDEC Tech Services QA

Audit notes: Included for comparison purposes.

Remarks: 1. The audit observations for the NO (nitric oxide) are included because the monitor response for NO is often

comparable to the monitor response to NO2 2. Monitor responses for NOx were several ppb lower than the responses for NO. These values were recorded in the

logbook. 3. Logbook complete and up to date.

Recommendations:

1. The concentration for NOx should never be lower than the concentration NO. This relationship should be kept in mind for all calibrations, precision and span checks.
