Dear Mr, be: 

Thank you for your request for our rvvicw of the transportation conformity determination 

for the Rock Hill, South CaroLina 8-hour ozone nmatrabment area and corresponding 

a Transportation Improvement Program (TIP). The Rock Hill-Fart Mill Area Tmport Study 

(RFATS) has responsibility for transportation plhg in the Rock Hill metropolitan area and 

has deveIoped a 2030 Long Range Transportation Plan (LRTP) for that area. The WATS 

tranrpomtion parrners engaged in a cooperative effort to determine transportation conformity for 

this area for the 8-hour ozone standard by June 15,2005 (i.e., a year after the effective date: of 

this area's nonattainmcnt designation for the 8-hour ozone standard). We have completed our 

review and recommend a finding of conformity for the 2030 RFATS LRTP and the 2006-2008 

TIP for the 8-hour ozone standard. 

On August 15,1997, and subsequently on July 1,2004. the Environmental Protection 

Agmq (?%A) published revisiom dated to the "Criteria and Procedures for Determining 

Conformity to State or Federal Implementation Plans of Transportation Plans, Programs, and 

Projects Funded or Approved Under Title 23 .U.S,C. or the Federal Transit Act," or 

Transportation Conformity Rule (40 C.F.R Part 93). These revisions outline the criteria that 

must be met for the 8-hour ozo~ standard. J3PA has reviewed tbe confomrity determination 

related to the 8-hour ozone standard for the 2030 LRTP and bas concluded that all of the cria 

including those outlined in the July 1,2004, conformity rule revision entitled, ''T~pottation 

Conformity RuIe Amendments: Conformity Amendments foT New 8-hour Ozone and PM2.5 

National Ambient Air Quality Standards, Response to March 1999, Court Decision and 

Additional Rule Changes" (69 FR 40004), have been met

Dear Ms. Wood: 

Enclosed for your review and comment the Rock Hill-Fort Mill Area Transportation Study 

(RFATS) Transportation Conformity Determination Report for the 2030 Long Range 

Transportation Plan (LRTP) and the FY 2007-2012 Transportation Improvement Program (TIP). 

The adopted FY 2007-20 12 TIP is a subset of the 2030 LRTP. 

The transportation conformity determination is based on a regional emissions analysis on the 

roadway and transit networks approved by RFATS and the South Carolina Department of 

Transportation (SCDOT) for the 2030 LRTP and emissions factors developed by the South 

Carolina Department of the Health and Environmental Control (SCDHEC). 

The MPO and the SCDOT provided SCDHEC and the public the opportunity for review and 

comment. The MPO included copies of the comments they received in the enclosed conformity 

determination reports. 

We request that you provide our office and the Federal Transit Administration (FTA) Region 4 

with your comments within 30 days of receipt of these documents, so we can give a timely 

response on the USDOT conformity determination. 

Please contact Mr. Dan Hinton at 803-253-3887, if you need additional information for your 

review.

Dear Mr. Lee: 

Thank you for requesting our review of the transportation conformity determination for 

the amended 2030 Long Range Transportation Plan (LRTP) and the amended Fiscal Year (FY) 

2007-2012 Transportation Improvement Program (TIP) for the Rock Hill-Fort Mill Area Transit 

Study Metropolitan Planning Organization (RFATS MPO) for the York County portion of the bistate Charlotte nonattainrnent area. These conformity determinations are for the 8-hour ozone 

standard, and are in accordance with the U.S. Environmental Protection Agency (U.S. EPA) 

guidance entitled, Companion Guidance for the July 1, 2004, Final Transportation Conformity 

Rule: Conformity Implementation in Multijurisdictional Nonattainment and Maintenance Areas 

for Existing and New Air Quality Standards. U.S. EPA's guidance allows the South Carolina 

and North Carolina portions of this bi-state nonattainrnent area to demonstrate conformity 

independently because there are budgets for a portion of this area, and there was an election 

made through interagency consultation to implement conformity requirements for each state 

independently. We have completed our review for the South Carolina portion of this area, and 

recommend a finding of conformity for the 8-hour ozone standard for the RFATS MPO's 

amended 2030 LRTP and the FY 2006-20 12 TIP. 

On August 15,1997, and subsequently on July I, 2004, and May 6,2005, U.S. EPA 

published revisions related to the."Critcria and Procedures for Determining Conformity to State 

or Federal Implementation Plans of Transportation Plans, Programs, and Projects Funded or 

Approved Under Title 23 U.S.C. or the Federal Transit Act," or Transportation Conformity Rule 

(40 Code of Federal Regulations Part 93). These revisions outline the criteria that must be met 

for the 8-hour ozone and PM2.5 standards. U.S. EPA has reviewed the conformity determination 

related to the 8-hour ozone standards for the amended 2030 LRTP and the amended FY 2007- 

20 12 TIP and have concluded that all of the criteria, including those outlined in the July 1,2004, 

conformity rule revision entitled, "Transportation Conformity Rule Amendments: Conformity 

Amendments for New 8-hour Ozone and PM2.5 National Ambient Air Quality Standards, 

Response to March 1999, Court Decision and Additional Rule Changes," (69 FR 40004), and 

those outlined in the May 6,2005, conformity rule revision entitled, "Transportation Conformity

Precursors" (70 FR 24280), have been met. 

We appreciate the opportunity to previously review advanced drafts of the conformity 

determination for the amended 2030 LRTP and amended FY 2007-201 2 TIP for the Rock HillFort Mill Area. The advanced drafts facilitated our review. If you have any questions regarding
