COMMONWEALTH OF VIRGINIA AREA 

DESIGNATION RECOMMENDATIONS UNDER THE 

2008 OZONE STANDARD

TECHNICAL SUPPORT DOCUMENT
2

BACKGROUND

On March 12, 2008, the U.S. Environmental Protection Agency tightened the National Ambient 

Air Quality Standard (NAAQS) for ground level ozone from 0.08 parts per million to 0.075 parts 

per million (ppm). This action was taken by EPA in light of new and compelling scientific 

evidence that a lower standard was needed to protect human health and welfare. 

One of the first actions required when a new air quality standard is established is to designate 

areas in regard to compliance with the standard. Those areas not complying with the standard 

are designated as “nonattainment” areas, while areas in compliance are designated “attainment”. 

Areas where insufficient data is available to make a determination are designated as 

“unclassifiable”. 

On December 4, 2008, the Principal Deputy Assistant Administrator, Robert J. Meyers, issued 

guidance to EPA and the states on the process and factors to consider when designating areas 

under the new ozone standard. In general, this guidance recommended the use of census 

bureau areas such as Core Based Statistical Areas (CBSA) or Combined Statistical Areas (CSA) 

as the starting point for nonattainment area designations when a violating ozone air quality 

monitor is present. However, EPA also allows states the flexibility to make area specific 

designations based on nine ozone related factors that are listed below:

• Ozone air quality data.

• Emissions data (location of sources and contribution to ozone).

• Population density and degree of urbanization.

• Traffic and commuting patterns.

• Growth rates and patterns.

• Meteorology (weather/transport patterns).

• Geography/topography.

• Jurisdictional boundaries.

• Level of control of emission sources.

The approach taken by Virginia to making individual jurisdiction determinations was furthermore 

based on the following hierarchy of criteria:

• Does the jurisdiction have a violating ozone monitor?

• Is the jurisdiction part of a current ozone nonattainment or maintenance area?

• Would exclusion of the jurisdiction create an illogical result, such as an attainment area 

within a larger nonattainment area?

• Does the jurisdiction significantly contribute to ozone formation in a nearby recommended 

nonattainment area?

In the case of areas that required a determination of significant contribution, if the area did not 

meet any of the other criteria, a clear and compelling case was required based on available data 

for the nine EPA factors to make a nonattainment recommendation.

The remainder of this document describes the analysis performed by the Virginia Department of 

Environmental Quality (DEQ) to support the designation recommendations that are being 

submitted to the EPA as part of the ozone standard implementation process. This analysis 

considers the major factors listed above as they pertain to each area in Virginia containing one or 

more monitors that are violating the new standard.

Once submitted, EPA will consider these recommendations and either accept or modify these 

recommendations. EPA will notify the Commonwealth of any modifications made to the state 

recommendations no later than November 12, 2009 and will provide a 30-day public comment 

period. The Commonwealth will then have an opportunity to submit additional information prior 

to EPA’s final issuance of designations by March 12, 2010.

Greater Washington DC/MD/VA Metropolitan Statistical Area

The Commonwealth of Virginia recommends that the areas of standard violation in Northern 

Virginia continue to be divided into two separate nonattainment areas. The precedent for these 

areas was previously set during the designation process for the 1997 ozone standard. In 

addition, the Commonwealth is recommending the addition of part of Caroline County that 

contains a monitor that also violates the ozone standard. The jurisdictions that make up these 

nonattainment areas are as follows:

Again, the Northern Virginia area will be part of the greater Washington, D.C. Nonattainment Area 

made up of the District of Columbia and jurisdictions from both Maryland and Virginia. 

As shown by the figures below, the Commonwealth believes that these nonattainment 

recommendations for the Virginia portion of the greater Washington, D.C. Metropolitan Statistical 

Area are reasonable and appropriate in that the recommended jurisdictions account for 92% of 

the ozone precursor pollutants, population, expected growth, and vehicle miles of travel for the 

area.

For the individual jurisdictions recommended for attainment status, the rationale used was that all 

these jurisdictions do not significantly contribute to the overall levels of the major ozone related 

criteria of emissions, population, growth, and vehicle traffic. Also in the specific case of Fauquier 

County, there is a ozone monitor located in this County that has a current design value of 0.071

parts per million and is in compliance with the new standard.

With regard to the Fredericksburg nonattainment area, a separate analysis was performed for the 

current ozone maintenance area and Caroline County. As can be seen by the figures below, the 

proposed nonattainment area again accounts for the majority of ozone related criteria.

Contribution of Recommended Areas to Selected Ozone Criteria 

In addition to the analysis provided above, and at the specific request of Caroline County, the 

Commonwealth recommends that only a part of Caroline County be designated nonattainment 

based on the following profile. In summary, this is a very rural area with no official designated 

urbanized areas within its boundaries. The vast majority of emissions in the County are the result 

of traffic passing through the area on both Interstate 95 and Route 301, which is a commercial 

traffic route to and from the Maryland eastern shore. Furthermore, the location of the monitor in 

Nonattainment

the northern tip of the County was specifically selected for its rural nature as an upwind 

assessment monitor for the Washington, D.C. area. In addition, about a third of the County is 

within the Fort A.P. Hill Military Reservation and is not available for private development. 

Additional details are provided below:

Caroline County

Analysis of Ozone Related Criteria

Emissions (2005) 2,241 tons/year VOC and 2,849 tons/year NOX (16.4% of ozone 

precursor emissions in the Fredericksburg area)

Emissions Density 0.026 tpy per square mile

Population (2005) 24,300 - 46 per square mile (8.3% of the total population in the 

Fredericksburg area)

Population Growth Population expected to grow to 36,058 by 2020 which represents only 

8.3% of the total population growth expected in the Fredericksburg 

area

Air Quality Noncompliance - Design Value (2006 to 2008): 0.081 ppm

Commuting Patterns The County workforce commutes almost equally to the 

Fredericksburg and Richmond areas.

Annual VMT (2005) 678 million Vehicle Miles of Travel (13% of total VMT in the area). 

Mostly through traffic on Interstate 95 and Routes 301 and 17.

Major Sources There is only one major source in the County, a natural gas fired 

electric generating station. However, this is a new facility that is 

highly controlled and subject to the CAIR utility control program. 

Total County point source emission of both VOC and NOX are less 

than 100 tons/year.

Meteorology Prevailing ground level winds are from the Southwest in the summer.

Geography County is located to the East and Southwest of the proposed 

nonattainment area.

Boundaries County is part of the Richmond MSA but part of the Fredericksburg 

Regional Planning Commission.

Level of Controls Currently subject to attainment permit and control requirements. 

Emissions should be significantly reduced by regional and national 

controls.

Richmond Metropolitan Statistical Area

The Commonwealth’s recommendation for the Richmond MSA is that the nonattainment area be 

the same as the previous 8-hour nonattainment area and current maintenance area. This

recommendation is based on the fact that the recommended nonattainment area accounts for the 

majority (~80%) of ozone precursor pollutants, population, expected growth, and vehicle miles of 

travel for the area. The counties and cities involved are provided below:

In general, the Richmond MSA covers a very large area of Virginia and includes a number of 

jurisdictions that are rural in nature and have no designated urbanized areas within their 

boundaries (similar to Caroline County as described in the Fredericksburg section). As such, the 

use of the EPA presumptive MSA boundary for the nonattainment area is not appropriate in this 

case. To illustrate this point, a series of relative density maps have been developed and are on 

the next page. As can be seen from these maps, the concentration of most of the ozone related 

factors and activities of ozone precursor emissions, population, growth, and vehicle travel are 

concentrated within the recommended nonattainment area boundary

In evaluating the remaining Richmond MSA jurisdictions, nothing distinguishes any of these 

jurisdictions as being significant contributors to the ozone formation in the area. Therefore, the 

Commonwealth recommends that all the remaining jurisdictions be designated as attainment 

areas.

Hampton Roads Metropolitan Statistical Area

The Commonwealth’s recommendation for the Hampton Roads MSA is that the nonattainment 

area be the same as the previous 8-hour nonattainment area and current maintenance area. 

This recommendation is based on the fact that the recommended nonattainment area accounts 

for 98% of ozone precursor pollutants, population, expected growth, and vehicle miles of travel for 

the area.

The remaining two counties in the MSA are very rural and remote jurisdictions that, through the 

analysis of ozone contribution factors, do not significantly contribute to the recommended 

nonattainment area. It should also be noted that Currituck County in North Carolina is also part of 

this MSA. The Commonwealth is making no recommendation for this jurisdiction as part of this 

process. However, we understand that the State of North Carolina will recommend that this 

County not be included in the Hampton Roads nonattainment area and the Commonwealth 

supports this recommendation.
