1. Introduction 

During the week of September 9-12, 2013, Richard Guillot, Mike Crowe, and Michael Roberts with 

EPA Region 4’s Science and Ecosystem Support Division (SESD) conducted a technical systems audit 

(TSA) on the State of Tennessee’s Department of Environment & Conservation, Division of Air 

Pollution Control (TDEC-DAPC) and the Department of Health, Division of Laboratory Services 

(TDOH-DLS). The TDEC-DAPC operates and maintains the ambient air pollution monitoring network 

in Tennessee and the TDOH-DLS analyze filters for the fine particulate matter (PM2.5) pollutant 

program. The TDOH-DLS also analyze filters for the Memphis-Shelby County Health Department, 

Metropolitan Health Department of Nashville Davidson County and the Knox County Health 

Department. This TSA was conducted to meet requirements found in 40 CFR Part 58 Appendix A. The 

TSA focused on data collected during the three year period of 2010 – 2012. Data from EPA’s Air 

Quality System (AQS) was used to evaluate network performance along with an audit questionnaire 

included as appendix A of this report. Tennessee staff interviewed during the TSA included personnel 

from the areas of: 

Monitoring Maintenance / Quality Assurance Laboratory 

Barry Stevens Cathy Stoecker Dr. Bob Read 

Quincy Styke Rex Bracy Craig Edwards 

Robert Brawner Lance Allen Dr. Susan Burchfield 

Billy Pugh Radford Strong Tim Morris 

Evelyn Haskin Anthony Wilson 

 Susan Aldridge 

 Shannon Miller 

2. Summary 

The TSA for the State of Tennessee revealed two major concerns and several other concerns with 

respect to the ambient air monitoring program. The first major concern was the significant portion of 

PM2.5 data flagged with a “1” in the AQS during 2011-2012. The State operated two PM2.5 weigh 

laboratories at the timeof this audit. Both of these labs began experiencing environmental control 

problems (temperature and relative humidity). Efforts were made by the State to repair the failed 

environmental systems. These repair efforts were unsuccessful, with a cycle of repair and failure until 

the decision was made to contract a private laboratory to take over all of the weigh laboratory duties 

until replacement of the environmental systems could be accomplished. The State decided to close one 

of its laboratories (Knoxville) and focus all efforts into the Nashville lab. The “1” flag is an indicator of 

a “critical criteria” for this pollutant measurement method not being met. EPA guidance recommends 

data not meeting a critical criteria be invalidated. EPA Region 4 has consistently followed this guidance 

and will recommends the State invalidate this data unless it can present evidence as why it should be 

retained. The data impacted was collected from mid 2011 through mid 2012 for the State, Memphis, 

Nashville and Knoxville agencies and totals approximately 30% of the data set for each of these 

agencies. EPA Region 4 is recommending the TDEC-DAPC review data back through 2010 for this 

issue. 

The second major concern is the lack of quality assurance information for monitors in AQS classified as 

“Industrial”. For 2010-2012, AQS shows 29 monitors meeting this classification, two of these monitors 

are used in the State monitoring plan to meet EPA minimum monitoring requirements. These two 
Page 5 of 9

SESD Project ID# 13-0544 

monitors should meet all of the requirements of a State and Local Air Monitoring Station (SLAMS). 

The state was unable to provide any documentation regarding quality management plans, quality 

assurance project plans or standard operating procedures for these monitoring sites. EPA recommends 

that the remaining “Industrial” monitors be reclassified as “non-regulatory” to avoid confusion in AQS 

as to the purpose of these monitors. 

Concerns noted in the TSA included: pending staff retirements and the need for additional staff in the 

areas of data handling, maintenance and quality assurance, the age of the site calibration equipment 

throughout the monitoring network, extended oversight of the local agencies – EPA would like to see 

the State take a stronger role in performing TSA’s. 

 

3. Findings and Recommendations 

3.1 Program and Data Management 

1. Finding: A significant portion of the PM2.5 raw data for the 2011 and 2012 monitoring years 

are flagged in the AQS with a “1” flag indicating a critical criteria has not been met. 

Discussion: During 2011-2012 the State of Tennessee’s Department of Health (TDOH) 

operated two PM2.5 weighing laboratories located in Nashville and Knoxville. The TDOH 

weighs filters for the following ambient air monitoring agencies: the State of Tennessee, the 

Metropolitan Health Department of Nashville-Davidson County, the Memphis Shelby 

County Health Department and the Knox County Health Department. In 2011, each of these 

laboratories began experiencing environmental control problems – primarily humidity 

control. A cycle of equipment failure and repair began in the laboratories until August 2012 

at which point a decision was made by the DOH to temporarily contract a private laboratory 

to handle the filter weighing responsibilities. The Department of Health has since replaced 

the environmental control system for the Nashville weigh laboratory. The Nashville 

laboratory began processing filters again in July 2013. Due to resource limitations the weigh 

laboratory in Knoxville was permanently closed and those duties transferred to the Nashville 

laboratory. 

EPA specifies a 30-40% mean relative humidity with a ±5 relative humidity percent control 

range over 24 hours, these specifications can be found in 40 CFR Part 50 Appendix L §8.2.3, 

8.2.4. EPA’s Quality Assurance Handbook for Air Pollution Measurement Systems 

identifies these specifications as a “critical criteria” for the measurement of PM2.5. The 

Handbook further states that “Observations that do not meet each and every criterion on the 

Critical Criteria Table should be invalidated unless there are compelling reasons and 

justification for not doing so.” 

Recommendation(s): All of the fine particulate monitoring data (PM2.5) from 2011 through 

2012 currently flagged in the AQS with a “1” flag indicating an unmet critical criteria should 

be invalidated. Invalidation of the data would mean removal of the concentration data and 

replacement with the appropriate null data code. This will impact the PM2.5 data collected 

by: the State of Tennessee, Memphis-Shelby County, Nashville-Davidson County and 

Knoxville-Knox County air monitoring programs. Chattanooga-Hamilton County did not 
Page 6 of 9

SESD Project ID# 13-0544 

utilize the State of Tennessee’s weighing laboratory for its PM2.5 monitoring program so is 

not required to take any of these actions. The State of Tennessee and the impacted local 

agencies should coordinate their efforts in identifying and flagging the data consistently in 

the AQS. A post audit review of the 2010 data shows the possibility these laboratory issues 

may have extended beyond the 2011-2012 timeframe. EPA Region 4 recommends the 2010 

PM2.5 data be reviewed and invalidated as necessary. 

In addition, EPA recommends the TDEC-DAPC) take a more active quality assurance role in 

the oversight of the PM2.5 weighing laboratory. The DAPC should conduct an annual 

technical systems audit of the PM2.5 laboratory and review the quality assurance data for lab 

operations quarterly. 

2. Finding: The State of Tennessee does not have sufficient quality assurance procedures 

and/or documentation to demonstrate that the monitors classified as “Industrial” in the AQS 

meet EPA regulatory requirements. 

 

Discussion: The State of Tennessee submits criteria pollutant data to the AQS which is 

collected by industries operating in Tennessee under the States permit authority. For 2010-

2012, data were submitted to the AQS for 29 industrial monitors located at 16 separate 

monitoring sites. Each industry is responsible for all quality assurance procedures for their 

respective monitoring network. The State of Tennessee submits this quality assurance data to 

the AQS for the industry but does not conduct a review of this information. The State of 

Tennessee does not review or approve any Quality Assurance Project Plans (QAPP’s) or 

Standard Operating Procedures (SOP’s) the industries may use in the operation of their 

monitoring network. The State of Tennessee does conduct quarterly performance audits on 

these industrial monitors. 

The State of Tennessee has utilized two of these industrial monitors to meet EPA’s minimum 

regulatory requirements for the number of monitors required in its network design plan. 

These monitors are the lead (Pb) monitor (AQS # 47-163-3001) located in Sullivan County 

and a sulfur dioxide (SO2) monitor (AQS# 47-163-0007) located in Sullivan County. These 

two monitors must meet all EPA regulatory requirements found in 40 CFR Parts 50, 53, 58. 

A review of the precision and accuracy data in AQS for the industrial monitors shows 

potential issues with the data. The State did not have any documentation available to 

demonstrate the data quality. 

Recommendation(s): The State of Tennessee must take steps to ensure that the two monitors 

used to fulfill network design requirements meet all of the EPA regulatory requirements 

found in 40 CFR Parts 50, 53, 58. The State of Tennessee can accomplish this by either 

establishing state owned monitors adjacent to the industry monitors and operating them 

according to an EPA approved QAPP and SOP; or by require the industry to submit a QAPP 

and SOP to the State for review and approval. In addition, TSAs must be conducted on those 

industries to ensure compliance with EPA requirements. Ultimately, the State must be able 
Page 7 of 9

SESD Project ID# 13-0544 

to demonstrate that the data collected for any of the monitors used for regulatory decision 

making purposes meets all of the EPA requirements. 

The State of Tennessee should also reclassify the 27 remaining monitors as “NonRegulatory” in the AQS. This will make it clear to all data users that the data collected by 

these monitors do not meet EPA regulatory requirements and should not be used for decision 

making purposes. 

3. Finding: Staffing Levels for Data Management, Maintenance, Quality Assurance 

Discussion: Tennessee operates its ambient air program with a small staff. Currently the 

data management area has three staff members, maintenance has two staff and quality 

assurance has two staff members. As with many of the ambient air monitoring programs in 

Region 4, most of the staff is approaching the point where retirement is an option. Once 

these senior staff begins to retire they will be taking a great deal of knowledge concerning the 

ambient monitoring program with them. In addition, each of the local programs in Tennessee 

have already experienced “turnover” in their respective ambient air monitoring staff. 

Recommendation(s): EPA strongly recommends the State begin succession planning for any 

pending retirements. Ideally, this would entail hiring new staff to work and train with 

experienced staff prior to any retirements. EPA also recommends additional staff for each of 

the areas of data management, maintenance and quality assurance. These staff would 

provide the state with the resources needed to meet the challenge of increased oversight of 

the local agencies and the industrial monitoring networks as well. 

4. Finding: Continue Updating Standard Operational Procedures 

Discussion: Tennessee has begun a process of updating its standard operating procedures. 

As noted above with the personnel changes occurring and the potential loss of knowledge 

through retirements the updating of the SOP’s would provide a basis for new employees to 

recover some of that knowledge. 

Recommendation(s): EPA recommends completing the updating of the SOP’s as soon as 

possible. 

3.2 Field and Maintenance Operations 

 

1. Finding: Need to replace the aged calibration equipment currently in use 

Discussion: The auditors found that the calibration equipment in the state network is aged 

and in need of replacement. Tennessee utilizes Dasibi® brand calibration equipment in the 

network, Dasibi® has been out of business since the early 1990’s. While Tennessee has done 

an excellent job of maintaining this aged equipment and keeping the various models in 
Page 8 of 9

SESD Project ID# 13-0544 

operation spare parts for these monitors are becoming difficult to get. This will eventually 

result in increased data loss unless the calibration equipment is updated. 

Recommendation(s): EPA recommends purchasing new equipment as resources are 

available. 

3.3 Quality Assurance 

1. Finding: More extensive quarterly audits are needed. 

Discussion: The audit team would like to commend Tennessee’s efforts for conducting 

performance audits on all of the monitoring network instrumentation in each monitoring 

agency each quarter versus the required once per year for each instrument. These 

performance audits help bound the data and have saved data in the past when quality 

assurance questions have arisen. As noted above the loss of personnel in the local agencies 

and potential loss in the state raises concerns about the quality of the data being collected by 

these inexperienced agencies. EPA technical systems audits are conducted on the three year 

schedule. 

Recommendation(s): EPA recommends the state expand its audit capabilities of the local 

agencies by incorporating an annual technical systems audit into one of the quarterly 

performance audit visits. 

4 Conclusions 

The significant loss of PM2.5 data in 2010-2012 should have been addressed more in a more timely 

manner. Tennessee should make every effort to ensure this cannot be repeated, better communication 

between the TDOH-DLS and the TDEC-DAPC and the local monitoring agencies is needed as well as 

expanded oversight by the TDEC-DAPC quality assurance staff. 

Tennessee must address the lack of quality assurance oversight with respect to the industrial classified 

monitors operating within the State. These monitoring data represent air quality used for regulatory 

decision making purposes and must comply with all CFR requirements. Tennessee should coordinate 

how they intend to address this issue with EPA Region 4. 

The problems noted in the audit indicate a strong need for more resources and oversight of local 

agencies by state personnel. EPA Region 4 believes that expanded oversight of the local programs will 

help ensure the generation of quality data throughout the state and local programs.

If an instrument goes down, at what length of time would you recalibrate the 

instrument before bringing it back online (24 hours, 48 hours, etc.)? 

According to SOP Section No. A.2.9.2 paragraph 15 ‘data following an analyzer 

malfunction or period of non-operation should be regarded as invalid until the next 

subsequent level one check unless unadjusted zero and span readings at that time can 

support its validity’. Therefore we would recalibrate if the zero and span readings show a

problem. Also, level 1 and precision checks are performed weekly.

values) within the data as recorded with the data in 

the computer files?

X

Does your agency document the data validation 

criteria including limits for values such as flow 

rates, calibration results, or range tests for ambient 

measurements?

X

 1. If yes, please describe what action the data

 validator will take if he/she find data with

 limits exceeded (e.g., flags, modifies, deletes,

 etc.)

Based on the difference from known tolerance 

limits for the response of the monitor, the data is 

subject to invalidation. Each monitor type has 

established ranges of performance for the data to be 

acceptable to use in population of the AQS 

database.

 2. If yes, give examples to illustrate actions taken

 when limits are exceeded.

Monitor is replace or repaired and any data is 

flagged appropriately from the last available valid 

performance checks.

How does the agency track missing data?

Daily logs are kept of each continuous monitor. Lab 

reports and field operator reports document missing 

data for non-continuous monitors.

Please describe how changes made to data that were 

submitted to AQS and AirNow are documented.

A monthly report that the operator reviews and then 

makes comments upon are used in conjunction with 

the daily log. The database is then updated prior to 

submittal.

Who has signature authority for approving 

corrections?

Name: Billy Pugh

Program Function: AQS Data Coordinator

What criteria are used to determine a data point 

should be deleted? Discuss briefly

Items such as invalid temperature ranges or monitor 

flow checks that provide evidence that the monitor 

was not properly functioning. Water in the lines and 

sporadic noisy responses are also things that we 

may use to justify invalidating a data point.

What criteria are used to determine if data need to 

be reprocessed? Discuss briefly

Are corrected data resubmitted to the issuing group 

for cross-checking prior to release? X

During the review of the 

operator’s monthly reports.
