Public Comments & Responses

Public Comments

No public comments were received by the District Department of the Environment and the

Virginia Department of Environmental Quality on the base year 2011 emissions inventory 

document. Maryland Department of the Environment received a comment letter from US

EPA dated June 12, 2014. EPA sent a revised version of this comment letter dated June 27, 

2014. As required by 40 C.F.R. § 51.102(e), a complete record of these comments is located 

at the Air Division of the Maryland Department of the Environment. The department contact

to access this information is:

Director, Air and Radiation Management Administration, Maryland Department of the 

Environment

As required by § 2.1(h) of Appendix V of 40 C.F.R. Part 51, below is a summary of the 

comments received and responses thereto. Included is a brief statement of the subject, the 

identification of the commenter, the summary of the comment and the response (analysis and 

action taken). 

1. Subject: Use of IM240 program in Base Year 2011 onroad source emissions 

inventory development

Commenter: United States Environmental Protection Agency (EPA), Region III

Original Text (Comment letter dated June 12, 2014): With regards to the Onroad portion of 

the emissions inventory, specifically the vehicle inspection and maintenance coverage inputs 

for MOVES, Maryland cannot use the IM240 emissions test standards as part of the State's 

emissions inspection and maintenance (I/M) program. In August 2009, Maryland removed 

the IM240 test from the State's I/M program. This has been confirmed each year when the 

state submits to EPA a data analysis report for its I/M program as required by 40 CFR 

51.366. As such, Maryland cannot rely on the additional emission benefits received from an 

emissions inspection test that is not currently implemented within the State.

Revised Text (Comment letter dated June 27, 2014): EPA withdrew its comments regarding 

using emissions benfits from the I/M240 program in the base year 2011 onroad mobile 

emission inventory. The text in the revised comment letter is as follows – “In August 2009, 

Maryland removed the IM240 test from the State's I/M program. This has been confirmed

each year when the state submits to EPA a data analysis report for its I/M program as 

required by 40 CFR 51.366.”

Response: Maryland has worked with EPA to fix the technical comments identified in 

EPA's review of the SIP with relation to the IM240 program. MDE obtained a copy of the 

I/M input file that generated the EPA comment from Joseph Schulingkamp at EPA and 

compared it with the I/M input file that was part of the draft SIP submittal. MDE's 

comparison determined that the two files were inconsistent and the comment wasn't 

accurate. MDE discussed this inconsistency with Mr. Schulingkamp on June 20, 2014 

during which he verbally agreed that the I/M input file from MDE was correct and that he 

considered the issue resolved. MDE sent an email confirming resolution of this MOVES 
I/M input issue to Mr. Schulingkamp on July 1, 2014. Subsequently, EPA sent a revised 

comment letter dated June 27, 2014 conforming this.

2. Subject:

Commenter: United States Environmental Protection Agency (EPA), Region III

Text (Comment letters dated June 12, 2014 & June 27, 2014): As required by 40 CFR 

51.104, whenever a program is substantially revised at the state level, the state should then 

revise its State Implementation Plan (SIP) to reflect those changes. In general, when SIP 

approved emission reduction programs are revised at the state level, the state must perform 

an anti-backsliding analysis as required by Clean Air Act (CAA) section 110(1) and submit 

that demonstration as part of the SIP revision to remove or amend the relevant SIP measure. 

This analysis should demonstrate that the revised emission control program will not 

negatively impact the state's ability of attaining or maintaining the relevant NAAQS. Also, 

EPA's I/M requirements rule adds an additional requirement specific to I/M programs, that 

the revised program meet the applicable I/M program performance standard test set out in 40

CFR 51, Subpart S (using the current emissions factor mobile source model, MOVES).

Upon submittal of an I/M SIP revision by Maryland, along with the accompanying 

performance standard analysis and noninterfence demonstration, EPA would review the 

revision to ensure that the revised I/M program will continue to meet Federal requirements 

of both 40 CFR 51, Subpart S and the CAA.

Response: With respect to the comment regarding 40 CFR 51.104 and the revision of the 

IM SIP/ anti-backsliding analysis, MDE commits to working with EPA to resolve this 

comment/ submit any necessary SIP revisions or analysis before June 1, 2015.

Technical Corrections

1. Commenter: Virginia Department of Environmental Quality

Date received: April 23, 2014

Recipient: MWCOG

Comment: The VDEQ would like to request that the following revision be incorporated:

The Virginia Department of Environmental Quality would like submit revised 2011 commuter 

rail emission inventory estimates for northern Virginia for incorporation into the final 2011 

emission inventory to be submitted to the EPA as part of the Base Year 2011 emissions 

inventory (Washington DC-MD-VA 2008 Ozone NAAQS Nonattainment Area submittal). The 

commuter rail emission estimates for northern Virginia jurisdictions that were included in the

revision of the 2011 inventory that were sent out for public review were based on an ERTAC 

commuter rail study that was grown to CY 2011. Since that time, VDEQ has obtained actual 

CY 2011 commuter rail activity data and fuel consumption data from the VRE, along with 

equipment specific engine emission factors and has developed CY 2011 commuter rail emission 

estimates for northern Virginia which we feel more accurately represent the emissions 

associated with this source category.

2. Commenter: Virginia Department of Environmental Quality

Date received: June 30, 2014

Recipient: MWCOG

The Virginia Department of Environmental Quality requested to submit a minor revision to the 

2011 point source NOx emission inventory estimate for the Prince William county. This 

revision decreased the average ozone season day NOx emission for the county and the northern 

Virginia from 13.38 tons per day to 12.96 tons per day. 

Response: MWAQC and the states agree. The changes will be reflected in the final 

document.
