## PublicHealth Prevent. Promote. Protect.

In accordance with the provisions ofthe Memorandum ofAgreement (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 of2008. Of primary interest is the installation ofthe 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 of75 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 ofthe Core Based Statistical Area Near Road N02Monitoring . 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 ofTennessee 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 S02analyzer 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 ofthe status on the monitor and has given the SCHD approval totemporarily 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 ofozone 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 ofone halfton per year or greater. The emissions inventory indicates that there are no sources with emissions ofone halfton or greater. Therefore, the SCHD does not anticipate having to do any lead source sampling. However, lead monitoring is a component ofthe NCORE site. Lead sampling began on January 4 , 2012. Ifyou have any questions, please call me at (901) 222-9578. Sincerely,

Robert Rogers, P.E . I Technical Manager Pollution Control
