Dear All, 

HELEN MORROW , M . D. 

HEALTH OFFICER Public Health Prevent. Promote . Protect. 

In accordance with the provisions of the Memorandum of Agreement (MOA) between our respective agencies, this 

document serves as a notification of changes described in the MOA between the Shelby County Health Department 

(SCHO), Mississippi Department of Environmental Quality (MDEQ), and the Arkansas Department of Environmental 

Quality (ADEQ) signed May and June of 2008. Of primary interest is the installation of the Near Road Air Monitoring 

Station located at Southwest Tennessee Community College (47-157-0100). Nitrogen Dioxide (trace level) and 

Carbon Monoxide (trace level) are measured at this site. 

NCORE 

Shelby County was chosen by EPA as one of 75 NCORE site locations, nationally. This multi-pollutant air monitoring 

station is located at 6388 Haley Road (47-157-0075) in the Shelby Farms area. 

Shelby County was in the Second Phase of the Core Based Statistical Area Near Road N02 Monitoring. The station 

includes equipment for multi-pollutant monitoring for N02 and CO. A site location on the campus of Southwest 

Tennessee Community College was selected and approved on November 14, 2013 by the EPA. A fully executed 

easement by the State of Tennessee was approved on February 10, 2014. This site is located at 5767 Macon Cove 

(47-157-0100). The site became operational on July 1, 2014. 

The SCHD currently monitors for CO at three site locations: NCORE (47-157-0075) (trace level), Near Road (47-

157-0100) (trace level) and the Alabama Station (47-157-0024). 
The SCHD is currently operating a trace level S02 analyzer at the Shelby Farms NCORE site. 

The PM 2.5 continuous monitor (TEOM) is temporarily discontinued at the Alabama (47-157-0024) site. The EPA 

was notified on September 19, 2011 of the status on the monitor and has given the SCHD approval to temporarily 

discontinue this sampling until funds are located to replace the monitor. This monitor began to malfunction on July 

25, 2011 . This information has been notated in AQS. 

The SCHD continues to operate a PM 2.5 continuous monitor (TEOM) at the NCORE station. 

THE SCHD currently monitors for PM 10 at the Gas Service Center (47-157-0016) (collocated monitors) and the 

Alabama Station (47-157-0024). 

OZONE 

The ozone monitoring requirement for NCORE increases the number of ozone analyzers in Shelby County to three at 

the following sites: 47-157-0021 , 47-157-0075 and 47-157-1004. 

The current lead (Pb) NAAQS requires identifying sources of lead emissions of one half ton per year or greater. The 

emissions inventory indicates that there are no sources with emissions of one half ton or greater. Therefore, the 

SCHD does not anticipate having to do any lead source sampling. However, lead monitoring is a component of the 

NCORE site. Lead sampling began on January 4, 2012. 

If you have any questions, please call me at (901) 222-9578. 

Sincerely, 

Robert Rogers, P.E. I Technical Manager

Memphis, Tennessee-Mississippi-Arkansas Metropolitan Statistical Area of monitoring 

network changes. The MOA between SCHD, MDEQ, and ADEQ is to collectively meet 

United States Environmental Protection Agency (EPA) minimum monitoring 

requirements for particles of an aerodynamic diameter of 10 micrometers and less (PM 

10), particles of an aerodynamic diameter of 2.5 micrometers and less (PM 2.5), and 

ozone; as well as other criteria pollutants air quality monitoring deemed necessary to 

meet the needs of the MSA as determined reasonable by all parties. This MOA will 

formalize and reaffirm the collective agreement in order to provide adequate criteria 

pollutant monitoring for the Memphis, TN-MS-AR MSA as required by 40 CFR 58 

Appendix D, Section 2, (e).

activities for the MSA. Each affected agency shall inform the other affected agencies 

via telephone or email of any monitoring changes occurring within its jurisdiction of the 

MSA at its earliest convenience, after learning of the need for the change or making the 

changes. Such unforeseen changes may include evictions from monitoring sites, 

destruction of monitoring sites due to natural disasters, or any occurrences that result in 

an extended (greater than one quarter) or permanent change in the monitoring network.
