## VA NETWORK CHANGES 2013

### VIRGINIA DEPARTMENT OF ENVIRONMENTAL QUALITY AIR QUALITY MONITORING NElWORK CHANGES INSTRUMENTATION CHANGES SINCE LAST REVIEW JULY 1, 2012 to JUNE 30,2013 51-510-0009, L-126-C Alexandria Health Department, City ofAlexandria, AQCR7 On August 21,2012, the Office 

### ofAir Quality Monitoring shutdown the existing monitor site located atthe Alexandria Health Department Building on North St. Asaph Street In Alexandria City. The site was shut down due tothe eminent closure ofthe building In which the monitoring equipmentw.. located. The location has been In the Virginia ambient air monitoring network since 1980. Day to day operation ofthis site was perfonned bythe City ofAlexandria Department of Public Health employees. The continuous monitors, N02, S02, CO and Ozone, were relocated to 3200 Colvin Street In the City ofAlexandria. The entry below describes this location. The PM10 monitorwas not relocated to the new location duetothe amount and the proximity of local Industrial and commercial activity. 51-510-0021, L-126-1 , Alexandria Transportation Warehouse, 3200 Colvin Street, City ofAlexandria, AQCR7As described above, the Old St. Asaph Street site (51-510-0009) has been relocated to 3200 Colvin Street. This site now monitorsfor N02, S02 and CO. The ozone (03) monitor has been designated a special purpose monitorduetothe numberof potential Interferences In close proximity to the site. The picture below illustrates the potential interferences.

X. Monitoring site probe location A. Railroad Switching Yard - 2150 yards from monitor probe line Intakes B. Alexandria City Bus (DASH) Maintenance and Storage Facility - 110 yards C.

- 1-Due to the proximityto the asphalt operation and the bus maintenance facility along with othersiting difficulties the PM10 monitorthatwas operating atthe Old Saint Asaph St. site has been deactivated. In its place DEQ has reasslgn1 ed theTucker Elementary School PM10 site (AQS 51-510-0020) from a Special Purpose Monitor (SPM) to a SLAMS monitor. The original SPM designation was made because the monitorwas required through a local requirement directed at a local business. Historical review ofthe data from the Tucker Elementary School monitor indicates thatthe results are representative and consistentwith the results from the StAsaph streetsite. Data from the newsite began August 24, 2012. 51-047-0002, 42-B, Farmington Elementary School, Culpeper, Culpeper Co, AQCR7 This site housed a PM10 samplerthatwas located in a rural area. This monitorwas shutdown effective December 31,2012. The last sampling date was December 29,2012. The table below indicates the highest and second highest maximum 24 hour concentrations overthe last 3 calendar years. Data below is from DEQ's Annual Air Monitoring Report and is based on certified data gathered currently available in AQS.

51-187-0004, 30-E, Warren Co. Memorial Hospital, Front Royal, Warren Co., AQCR2 This site housed a PM10 samplerthatwas located In a rural area. This monitorwas shutdown effective December 31,2012. The lastsampling datewas December 29,2012. The table below Indicates the highest and second highest maximum 24 hourconcentrations overthe last 3 calendar years. Data below Isfrom DEQ's Annual Air Monitoring Report and is based on certified data gathered currently available in AQS.

51-760-0024, 158-W, Science Museum ofVirginia (SMV), Broad Street, Richmond City, AQCRS The monitoring site located atthe Science Museum site in Central Richmond City was shutdown effective December 31, 2012. The reason forthis shutdown was dueto the complete renovation ofthe entire area behind the Science Museum to make room for a new public gathering facility associated with the Science Museum and forthe NewWashington Redsklns training facility. This site housed a continuous Carbon Monoxide (CO) monitor, Sulfur Dioxide (S02) monitorand a Nitrogen Dioxide (N02) monitor. Data collection forthese analyzers ended at midnight, December 31,2012. 51-770-0015, 109-M, Round Hill Montessori Elementary School, Roanoke City, AQCR2 This sitewas shut down on March 8, 2013 due to school construction. Review ofthe proposed plans Indicated thatthere will be no room for replacing the site on the Round Hill property based on siting criteria In Subpart 58 Appendix E. The powerto the shelterwas disconnected on March 8, 2013. The PM2.5 samplers (2025 and TEOM) and supportequipment was removed on March 13, 2013 and brought backto the shop atAQM for refitting and repair. The CO monitorwas**pl~ced** atthe Vinton Shelter In Roanoke County (AQS 51·161-1004). The PM2.5 and the TEOM monitors will be relocated to theVInton shelter as well. Prior to placing the monitors atthe Vinton shelterthe sitewill have to have sometrees cut and the fence line 

### will have to be expanded to accommodatethe PM2.5FRM monitor. Statistical analysisfrom the Office of Risk Assessment has indicated thatthe Salem PM2.5 monitor data (AQS 51-775-0011) -2-

### represents a statistically similar data setsothe Salem High School FRM (AQS**51-775~011)** 

### will be used as Indicative ofthe PM2.6 results In the Roanoke area untilthe VInton site is properly outfitted. 51-113-0003, 36-A, Big Meadows SNP, Madison Co. AQCR7 The TEOM continuous particulate monitor began falling the Data Quality Objectives on December 26, 2012. A flow check was performed and the monitorfailed the QA 

### checks. Evaluation ofthe monitor Indicated that It had an Internal hardware failure. Parts have been ordered and the monitorwaa shutdown and will be restarted upon Installation ofthe new parts. A review ofthe data resulted In Invalidating the TEOM data backto July 2012. 61-760-XXXX Richmond Near Road Site, Bryan Park Interchange (N 37° 35'26.9", W 77° 28' 8.9") All local approvals have been received forthe Richmond Area Phase I near road monitoring site. The site footprint has been staked out In the park and the electrical contractor has provided the electrical specifications and a Purchase Order has been Issued. The shelter has been purchased and Is currently atthe AQM office awaiting the completion ofthe electrical Installation. Projected Date to begin data collection Is June 12,2013. The approved site Is shown on the map below.

61-069-XXXX Hampton Roads Near Road Site, l-64/l-2641nterchange (N 38° 51'11", 78°11'42") The Norfolk Planning Department has waived planning committee approval forthe Near Road Monitoring Site application and has forwarded the requesttothe city manager's office. The shelterforthis site Ia being stored ata local DOT residency until the leasing agreement approval issigned. Projected date to have the shelteron site Ia June 30, 2013. Proposed site is shown on the map below. -3.

### Virginia Continuous Air Monitoring Sites Data Acquisition System All Monitoring sites that contain continuous analyzers have been incorporated ontothe Virginia DEQ Air Data Acquisition System. The communications between all sites have been upgraded from dial up modems to internet communications based router/modems. All sites have been upgraded to In-line pressure transducers on the gas cylinder supplies forthe zero/span/ precision checks. The Hanover Site (AQS 51-085-0003) will be upgraded to automated quality hardware and will be enabled with remote QAQC procedures byJuly 1, 2013. ANTICIPATED INSTRUMENTATION CHANGES JULY 1, 2013 through JUNE 30, 2014 51-087-0014, 72-M MathScience Innovation Center, Henrico County; AQCRS - PAMS Auto GC The MSIC monitoring site is currently designated the NCore monitoring site forthe Commonwealth ofVirginia. In anticipation ofthe PAMS re-engineering effortAQM will relocate the PAMS Automated Gas Chromatograph from the currently designated PAMS monitoring site at ourCorbin site in Caroline County (AQS 51-033-0001) tothe NCore site atthe MathScience center. The MathSclence Center has an existing NOy monitor, NOx monitor, meteorological equipment and an ozone monitorsothatthe additional required monitoring forthe PAMS program currently Is In place. The Auto GC will be in place in time forthe beginning ofthe PAMS season i.e. June 1, 2012. 51-033-0001, 48-A, USGS Geomagnetic Center, Corbin, Caroline County; AQCR7- NOx and NOy The Auto GC that historically been located in the Corbin monitoring site, as described above, will be started up atthe MathSclence Innovation Center.

Near Road Monitoring Sites 61-760-XXXX Richmond Near Road Site, Bryan Park Interchange (N 37° 35'26.9", W 77° 28' 8.9")- Carbon Monoxide The carbon monoxide monitorformerly housed atthe Science Museum ofVIrginia Site will be relocated to the near road monitoring site at Bryan Park in Richmond City. This will occurafter the N02 monitor atthe site has been established. This addition will likely occur late Summer 2013. 51.059-XXXX Hampton Roads Near Road Site, l-64/1-2641nterchange (N 36° 51'11", 76°11'42") Carbon Monoxide The Hampton Roads site isscheduled to be In place and operational by August30, 2013. This assumes thatthe appropriate approvals forthe site have been procured by June 1, 2013. Once the site is in place and demonstrated consistent operation, the CO monitorfrom the NOAA facility (AQS 61-170.0024) will likely be relocated to the Near Road Site. This Is expected 

### to occur priorto November 1, 2013.**Vir~lnia** 

### Continuous Air Monitoring Sites Data Acquisition System AQM will implement phase 2 and part ofphase 3 ofthe Data Acquisition System Implementation schedule. This Involves a hardware upgrade at both the Science Museum of VIrginia site (61-760.0024) In Richmond City and atthe Hanover County Site (AQS 51.085.0003). This hardware upgradewill facilitate the Initiation ofan automated Quality Assurance program thatwill allow regional operators and AQM technicians to perform zero/span/precision and calibration procedures from remote locations. Once these 2 sites have been tested and validated, hardware upgrades will be Implemented at all ofthe ozone-only sites asfollows:

Near Road Monitoring Sites ANTICIPATED SITE CHANGES JULY 1, 2013 through JUNE 30, 2014
51-059-XXXX, Near Road Site, Fairfax County, AQCR7 In addition tothe Richmond Area and Hampton Roads area Near Road Monitoring sites, the Northern Virginia area is also scheduled to have a Near Road site installed priorto January 1, 2014 i.e. a phase I monitoring site. The location ofthis monitoring site will be in the area known · as the Springfield
.interchange because It is the area of maximum Annual Average Dally Traffic (AADT) in the Washington Metropolitan Core Based Statistical Area (CBSA). Below Ia a satellite view ofthe proposed area ofthe monitoring site.

Two sites have been selected and evaluated forthis area so far: site A (N 38o 46' 54", W 77° 10' 50.23") - was determined to be too close to the adjoining overpass which is deemed an obstruction based onthe Technical Assistance Document. Site B (N 38o 47' 01", W 77° 10' 48.17")- was abandoned when negotiations broke down with the private landowner ofthe property. Additional sites have been selected but notyet analyzed. Once the Northern Virginia Near Road site has been Installed and has demonstrated consistent operation, the CO monitor located atthe -6-

### Aurora Hills VIsitor Center in Arlington Co. (AQS 51-013-0020) will be moved to this site perthe requirements ofthe August 2011 revised requirements forthe Carbon Monoxide air monitoring network. In addition, perthe requirements ofthe Dec 2012 PM2.5 revised NAAQS standards the site will be evaluated for Installation ofa PM2.5 monitor. The regulatory deadline ofthe PM2.5 Installation Is January 1, 2015. 51-139-0004, 29-D, Page Co. Airport, Luray, Page County; AQCR2 Airport officials Indicatethat DEQ will have to move this monitoring site dueto FAA regulations. Process of identifying a new site has just begun. AQM has metwith the Page County School Board about possible sites on School property. SPECIAL STUDIES ACTIVITIES SINCE LAST REVIEW JULY 1, 2012 to JUNE 30, 2013 VA DEQ Office ofAir Quality Monitoring received a grantfrom EPA 

### to studythe Methyl Bromide fumigation operations in Suffolk City (Hampton Roads, AQCR6). The Virginia Department of Health has provided extensive infonnatlon on recommended data gathering and evaluation and will be assisting with the Risk Assessment report thatwill be generated from the data gathered during this study. VA DEQ selected two facilities based on preliminary studies done In winter and summer of2010. At thetime both operations were fumigating atclose totheir maximum rate. When theIR camera studies were begun In fall of2012 the facilities were operating at a significantly reduced capacity due to market conditions in their primary targeted market, China. The IR camera results were inconclusive because the dilution ratio ofairto Methyl Bromide was elevated such thatthe concentration of Methyl Bromide was belowthe detection capability ofthe camera. The actual sampling runs begin in spring of2013. The first setofsamples gathered at each site will be to determinethe baseline or background level of Methyl Bromide. Several sets of samples will be taken at both facilities between April and June. The bulk ofthese sampling runs will 

### be performed when the facilities are notaerating (venting)the Methyl Bromide. These sampling runs will include grab (instantaneous) samplesto determine maximum concentration sites, hourly samples to compare versus the shortterm ambient concentration standard and 8 hoursamples to gather data to assess environmental exposure. The data from these samples will be senttotheVirginia Department of Health sothatthey can begin their health assessment ANTICIPATED SPECIAL STUDIES ACTIVITIES JULY 1, 2013 to JUNE 30,2014 Once the Initial background studies are complete (early June 2013) sampling will begin on ambient levels during the aeration phases ofthe fumigation process. Data will be collected on hourly and 8 hourtime scales. These sampling runs will be supported by the placement ofa Photo-ionization Detector networkto get a better spatial evaluation ofthe dispersion ofthe Methyl Bromide during the aeration process. The eight hoursamples will 

### be collected to determine overall exposure during the aerations and will be placed in areas where exposuretothe general public Is most likely. The aeration studies are projected to be completed in late fall of2013. The data generated from this study will be used to develop two documents: 1) A data quality report to demonstrate thatthe study has metthe DQO's ofthe project and 2) A risk assessment report generated bythe DEQ Office of Risk Programs. These documents will be used 

### by the Virginia Department of Health to develop the Risk Assessment report.
