Dear Secre~2Jtr 

FEB Z 1 2013 

By letter and enclosures dated June 22, 2012, the Virginia Department of Environmental 

Quality (VADEQ) submitted to the U.S. Environmental Protection Agency (EPA) an annual 

ambient air monitoring network plan in accordance with the regulatory requirements of 40 CFR 

Part 58- Ambient Air Quality Surveillance. Based on our review, EPA approves VADEQ's 

June 22, 2012 annual ambient air monitoring network plan on the basis that the plan meets the 

requirements of 40 CFR Part 58.10. 

Additionally, 40 CFR Section 58.11(c) requires any changes to the air monitoring network 

or design of the following air monitoring systems be approved by the EPA Administrator: 

a) Photochemical Assessment Monitoring Systems 

b) Particulate Matter Speciation Trends Network 

c) The National Core Monitoring Network 

EPA determined that VADEQ's June 22, 2012 annual ambient air monitoring network plan does not 

require approval from the EPA Administrator because there were no changes to any of the air 

monitoring systems listed above. 

If you have any questions, please do not hesitate to contact me or have your staff contact 

Dr. Jennie P. Saxe, EPA's Virginia Liaison, at (215) 814-5806. For questions regarding this 

approval action, your staff may contact Ms. Diana Esher, Director, Air Protection Division, at 

(215) 814-2706.

AIR QUALITY MONITORING NETWORK CHANGES 

INSTRUMENTATION CHANGES SINCE LAST REVIEW 

JULY 1, 2011 to JUNE 30,2012 

51-510-0009, L-126-C Alexandria Health Department, Alexandra, AQCR7 

On January 1, 2012, the Office of Air Quality Monitoring shutdown the PM2.5 FRM monitor 

located at the monitoring site in Alexandria City. This monitor began operating at this site on 

January 1, 2010. The monitor was placed there originally to address concerns expressed by the 

City of Alexandria regarding the impact of emissions from the Mirant/GenOn electric generating 

facility. The Company has notified the City of Alexandria of its intent to shutdown this facility 

which negates the original purpose for siting the monitor. 

51-013-0020, 47-T, Aurora Hills Visitor Center, Arlington Co., AQCR7 

Both the PM2.5 FRM monitor and the collocated monitor were shutdown at this site from 

November 29, 2010 until July 2, 2011 due to maintenance activities. The activities involved 

reroofing the building due to age and continued problems with leaks. The samplers began 

sampling in the 3rd quarter of 2011. 

51-087-0014, 72-M, MathScience Innovation Center NCore Site, Henrico County, AQCR5 

The MSIC site is the NCore location for Virginia. The NCore site was required to have the 

TSP lead monitor operating by a regulatory deadline of January 1, 2012. The TSP lead monitor 

has been installed and was operating prior to the regulatory deadline. 

Virginia Continuous Air Monitoring Sites Data Acquisition System 

On August 10, 2011, the Virginia Department of Environmental Quality began operating a 

new Data Acquisition System for the continuous air monitoring sites within the Commonwealth. 

This is the first step in a 3 step project to create a fully internet based Data Acquisition System 

that replaces the current dial up system data system. The new system is being maintained on a 

server in Round Rock, Texas by IPS Meteostar. The basic software being used is the IPSM 

licensed product LEADS. The stations that are currently being gathered on this new system are 

listed in Attachment A to this document. 

On April1, 2012 at the beginning of the official ozone data gathering season in Virginia, a 

new Air Monitoring Data web page was launched using the LEADS software and the new data 

polling system supported by the IPSM system. This web page allows the public to have access to 

near real time hourly data generated at the stations included in the polled network (attachment A). 

This page is also being used by regional monitoring operators as a means of checking the 

stations from any location and to schedule their visits accordingly. Once fully implemented, the 

public will have access to data as far back as 2000. 

ANTICIPATED INSTRUMENTATION CHANGES 

JULY 1, 2012 through JUNE 30, 2013 

Near Road Monitoring Sites - Carbon Monoxide 

51-013-0020, Aurora Hills Visitor Center, Arlington Co., CO Monitor, AQCR7 

51-760-0024, Science Museum of Virginia, Richmond City, CO Monitor, AQCR5 

51-170-0024, NOAA Facility, Norfolk City, CO monitor, AQCR6 

Above are the monitors projected to be moved to the roadside sites based on the 

requirements of the new Carbon Monoxide NAAQS standard. This move will occur in conjunction 

with the installation of the NOx monitoring sites. A fixed schedule will be worked out contingent 

upon the results of the NOx installation schedule. 

51-047-0002, Farmington ES, Culpeper Co., PM10 Monitor, AQCR4 

- 1 -
The PM10 Monitor is currently being reviewed as to the necessity of maintaining this 

monitoring site. This monitor may be removed prior to July 1, 2013. 

51-187-0004, Front Royal Memorial Hospital, Warren Co., PM10 Monitor, AQCR2 

The PM1 0 Monitor is currently being reviewed as to the necessity of maintaining this 

monitoring site. This monitor may be removed prior to July 1, 2013. 

Virginia Continuous Air Monitoring Sites Data Acquisition System 

AQM will implement phase 2 and part of phase 3 of the Data Acquisition System 

implementation schedule. This involves a hardware upgrade at both the Science Museum of 

Virginia site (51-760-0024) in Richmond City and at the MathScience Innovation Center (51-087-

0014) in Henrico County. This hardware upgrade will facilitate the initiation of an automated 

Quality Assurance program that will allow regional operators and AQM technicians to perform 

zero/span/precision and calibration procedures from their laptops. Once these 2 sites have been 

tested and validated, hardware upgrades will be implemented region by region until complete. 

Near Road Monitoring Sites 

ANTICIPATED SITE CHANGES 

JULY 1, 2012 through JUNE 30, 2013 

51-059-XXXX, Near Road Site, Fairfax County, AQCR7 

51-71 0-XXXX, Near Road Site, Norfolk/Virginia Beach, AQCR6 

51-760-XXXX, Near Road Site, Richmond City, AQCR5 

The revised NOx NAAQS required the implementation of a near road monitoring network 

to measure peak NOx road side concentrations. Virginia will be installing 3 sites based on 

population levels: one will be in Northern Virginia along the 95/395 Springfield Interchange; one 

will be in Richmond City at the Bryan Park Interchange; and the third will be in Hampton Roads at 

the intersection of 64/264 at the Virginia Beach/Norfolk border. The regulatory requirement for 

installation of these sites is January 1, 2013. 

51-770-0011, Cherry Hill Subdivision, Roanoke City, TSP-Lead and PM10, AQCR2 

The lead monitor at this location is a source oriented monitor targeting lead emissions 

from Roanoke Electric Steel DBA Steel Dynamics. Steel Dynamics has purchased the property 

upon which the monitor is placed so DEQ will relocate this monitor to Fair View Elementary 

School as soon as the MOU can be completed. The new location will not be influenced only by 

Steel Dynamics so a study will be initiated upon the relocation to correlate wind direction with 

monitor results to determine if individual lead emitters can be isolated. The existing PM10 

monitor will also be moved as part of this site relocation. 

51-510-0009, Alexandria Health Department site, Alexandria City, AQCR7 

In a letter from AQM to the Alexandria City Office of Environmental Quality, AQM 

conditionally approved the relocation of the Alexandria monitoring site from its currently location 

at 517 N. St. Asaph street to 3200 Colvin Street. The conditional approval is based on existing 

local factors that could negatively bias the ozone results from this site. There are two auto body 

shops within 2 blocks of the location as well as a recycled asphalt storage pile immediately 

adjacent to the site. Alexandria will relocate and operate this site with the current S02, N02 and 

CO monitors. Alexandria will operate the 03 monitor as a special purpose monitor for two years 

so that AQM can evaluate the date trends to determine if the variability of the data is consistent 

with other similar sites in the Northern Virginia area. 

SPECIAL STUDIES: 

VA DEQ Office of Air Quality Monitoring received a grant from EPA to study the Methyl 

Bromide fumigation operations in Suffolk City (Hampton Roads, AQCR6). DEQ will be conducting 

these studies through fall of 2012. The Virginia Department of Health has provided extensive 

information on recommended data gathering and evaluation and will be assisting with the Risk 

Assessment report that will be generated from the data gathered during this study. Field studies 

begin in Spring, 2012.
