by interagency consultation. This point in time should occur at the point at which the 

MPO (or TOOT, when applicable) or other designated agency begins to model the impact 

of the transportation plan or TIP on travel and/or emissions. New data that becomes 

available after an analysis begins is required to be used in the conformity determination 

only if a significant delay in the analysis has occurred, as determined through interagency 

consultation. 

13. Consultation shall be undertaken, and conducted in accordance with this rule, to evaluate 

events which will trigger new conformity determinations in addition to those triggering 

events established in 40 CFR §93. 1 04, including any changes in planning assumptions, 

that may trigger a new conformity determination. The consultation process pursuant to 

this rule shall be initiated by FHWA, EPA, TAPCO, TOOT, or the MPO where one exists. 

(e) Implementation Plans: 

.1. Any proposed revisions to the SIP, which may have a direct or indirect effect upon the 

motor vehicle emissions budget for an area subject to conformity, shall be made available 

to the MPOs specified in this rule, as well as TOOT, FHWA, FTA, and EPA in written or 

electronic form for their review and comment at least thirty (30) days before presentation 

to the Tennessee Air Pollution Control Board. Shorter review periods may be allowed 

occasionally in emergency situations with participant concurrence. 

2. TAPCO shall also provide the public a period from the date of announcement to comment 

on any proposed Sl P revisions which may have a direct or indirect effect upon the motor 

vehicle emissions budget for an area subject to conformity, as defined in subparagraph 

(h) of this paragraph. 

SS-7037 (January, 2009) 9 
3. Any proposed revisions to the SIP shall include documentation on methods of analysis, 

models employed and purpose of the revision. 

(f) Other processes: 

1. TAPCD shall be responsible for the process whereby MPOs, local air agencies, TOOT, 

FHWA, FTA and EPA shall study and develop supplementary consultation procedures to 

identify, evaluate and address, as needed, the following issues. In the absence of 

supplementary consultation procedures, TAPCD will include the following items for 

discussion during interagency consultation meetings in advance of a conformity 

determination: 

(i) Hot spot analysis methods, models and assumptions, 

(ii) Determination of regionally significant projects and projects considered to have a 

significant change in design concept and scope, 

(iii) Evaluating when exempt projects should be treated as non-exempt, 

(iv) Timely implementation of TCMs and processing of TCM substitutions, 

(v) Identifying conformity determination triggers other than those established in 40 

CFR §93. 1 04, and 

(vi) Methods, models and assumptions for regional emissions analysis. 

2. These supplementary procedures (in part 1 of this subparagraph) may be specific for 

each metropolitan area or each· nonattainment or maintenance area subject to the 

conformity rule. 

3. TAPCD shall conduct meetings to discuss any supplementary consultation procedures<. 

needed. 

4. Final document distribution for conformity determinations associated with Plans, TIPs and 

STIPs (occasionally, alternate schedules may be used with concurrence by participants): 

(i) 

(ii) 

(iii) 

(iv) 

SS-7037 (January, 2009) 

The final air quality conformity determination, necessary supporting 

documentation and the Plan and TIP will be submitted to the FHWA Division 

Office, the FTA Regional Office, the EPA Regional Office, TOOT, TAPCD and 

any applicable local air agencies. EPA will respond in writing, to the FTA 

Regional Office and FHWA Division Office, as soon as possible but not later than 

thirty (30) days from the date received; 

Comments will be resolved by FHWA and FTA, in concert with EPA, with the 

MPO or TDOT, in their respective areas, as necessary; 

FHWA and FTA will jointly prepare correspondence to make the conformity 

finding. Joint conformity findings will be addressed to the MPO (or TOOT where 

no MPO exists), with a copy to TOOT, EPA, TAPCD and any applicable local air 

agencies. The findings of FTA and FHWA together constitute the DOT conformity 

findings; 

In the event that the MPO or TOOT in their respective areas, wishes to amend 

the TIP to add projects that are exempt from the conformity analysis requirement, 

FHWA or FTA or both, if necessary, will concur in the amendment and re-affirm 

the original DOT conformity finding by letter. This re-affirmation letter will 

reference the date(s) of the original FHWA and FTA findings. In cases where tl~~ 

amendment involves projects that are not exempt, a new conformity analysis anu 

determination will be required, and will, in turn, require a new DOT conformity 

finding. 

10 
Within fifteen (15) days subsequent to approval and adoption of final documents, 

including transportation plans, TIPs, conformity determinations, applicable 

implementation plans and implementation plan revisions, the lead agency shall provide 

copies (electronic copies acceptable) of such documents and supporting information to all 

affected agencies. 

5. Generalized qualitative or interim hot-spot determination process: 

Interagency consultation shall be undertaken to evaluate and choose a model(s), 

associated methods and planning assumptions to be used in hot-spot analyses. 

Generalized qualitative or interim hot-spot determination process (occasionally, alternate 

schedules may be used with concurrence by participants): 

(i) The project sponsor (or TOOT or the MPO), will seek consensus if the project is 

believed to be exempt from hot-spot analysis. This can be accomplished through 

electronic transmittal, providing for a minimum of fourteen (14) days for review. If 

requested, an additional fourteen (14) days will be provided for review, as well as 

any additional information needed to make the determination; 

(ii) If the project is not exempt, the project sponsor (or TOOT or the MPO) will collect 

and organize and distribute specific data needed to determine whether 

nonexempt projects are or are not of air quality concern. This can be 

accomplished through electronic transmittal, providing for a minimum of fourteen 

(14) days for review. If requested, an additional fourteen (14) days will be 

provided for review, as well as any additional information needed to make the 

determination; 

(iii) If it is determined the project is a project of air quality concern, the project 

sponsor (or TOOT or the MPO) will then engage and begin a consultation 

process to evaluate and choose a model (or models) and associated methods 

and assumptions to be used in hot-spot analysis. The project sponsor (or TOOT 

or the MPO) will make a PM2.5 hot-spot determination (i.e., project-level 

conformity determination) and request that other stakeholder agencies comment 

on the conclusions through formal interagency consultation as provided in this 

rule. 

6. Regionally significant projects: 

For purposes of regional emissions analysis, the MPO (TOOT where no MPO exists) 

shall actively consult with the affected agencies to determine which minor arterials and 

other transportation projects should be considered "regionally significant" projects (in 

addition to those functionally classified as principal arterial or higher or fixed guideway 

systems or extensions that offer an alternative to regional highway travel) and which 

projects should be considered to have a significant change in design concept and scope 

· from the transportation plan or TIP. Prior to initiating any final action on these issues, the 

MPO (or TOOT, if applicable) shall consider the views of each agency that comments 

and respond in writing. 

7. Transportation Control Measures (TCMs): 

(i) 

SS-7037 (January, 2009) 

For each Plan or TIP update, the agencies specified in this rule to participate in 

consultation, shall review whether past obstacles to implementation of 

Transportation Control Measures (TCMs) which are behind the schedule 

established in the applicable implementation plan are being overcome, and 

whether State and local agencies with influence over approval or funding for 

TCMs are giving maximum priority to approval or funding for TCMs. If 

necessary, consideration will be given as to whether delays in TCM 

11 
implementation necessitate revisions to the applicable implementation plan to 

remove TCMs or substitute TCMs or other emission reduction measures. 

(ii) Where TCMs are to be included in an applicable implementation plan, a list · 

TCMs shall be developed by TOEC (and local air agencies, if applicable) in 

cooperation with the MPO, TOOT, or both. 

8. Exempt projects which may be non-exempt: 

The MPO (or TOOT where applicable) shall commence consultation regarding potentially 

exempt projects to (occasionally, alternate schedules may be used with concurrence by 

participants): 

(i) Identify exempt project as defined by 40 CFR §93.126 Table 2, and 40 CFR 

§93.127 Table 3; 

(ii) Identify exempt projects and categories of exempt projects which should be 

treated as non-exempt because they may have adverse air quality impacts and 

determine appropriate air quality analysis methodologies for analyzing such 

projects; 

(iii) Identify transportation Plan and TIP/STIP revisions which add or delete exempt 

projects, as defined in 40 CFR §93.126 Table 2 and 40 CFR §93.127 Table 3. 

The MPO (or TOOT where applicable), will seek consensus from the consultation 

participants if the project is believed to be exempt. This can be accomplished through 

electronic transmittal, providing for a minimum of fourteen (14) days for review. If 

requested, an additional fourteen (14) days will be provided for review, as well as any 

additional information needed to make the determination. 

9. Multi-jurisdictional consultation: 

Agencies specified in this rule will consult on emissions analysis for transportation 

activities which cross the borders of MPOs or nonattainment areas or air basins. Where 

the nonattainment area crosses the boundaries of multiple MPOs, the MPOs shall share 

cooperatively the responsibilities of conducting conformity determinations on 

transportation activities. The MPOs will enter into a memorandum of agreement which 

will define the effective boundaries and the respective responsibilities for each MPO for 

regional emissions analysis. Adjacent MPOs of nonattainment or maintenance areas 

shall share information concerning air quality modeling assumptions and emissions rates 

that affect both areas. This provision also applies. to MPOs and TOOT where the 

nonattainment area extends beyond the MPO's boundary. TAPCO and/or local air 

agencies (where applicable) will initiate consultation with other states when 

nonattainment areas extend beyond Tennessee's borders. 

10. Project disclosure: 

(i) 

SS-7037 (January, 2009) 

The sponsor of any potentially regionally significant project, and any agency that 

is responsible for taking action(s) on any such project, shall disclose such project 

to TOOT or the MPO (whichever is. appropriate) in a timely manner. Such 

disclosure shall be made not later than the first occasion on which any of the 

following actions is sought: any policy board action necessary for the project to 

· proceed, the issuance of administrative permits for the facility or for construction 

of the facility, the execution of a contract to design or construct the facility, the 

execution of any indebtedness for the facility, any final action of a board, 

commission or administrator authorizing or directing employees to proceed with 

design, permitting or construction of the project, or the execution of any contra-. -. 

to design or construct or any approval needed for any facility that is dependem 

on the completion of the regionally significant project. To help assure timely 

disclosure, the sponsor of any potential regionally significant project shall 

. 12 
) 

disclose to TOOT or the MPO (whichever is appropriate) on a schedule 

prescribed by TOOT or the MPO (whichever is appropriate), but no less than 

annually, each project for which alternatives have been identified through the 

NEPAprocess, and any preferred alternative that may be a regionally significant 

project. The consultation process shall include assuming the location, design 

concept and scope of the project, where the sponsor has not yet deCided these 

' features, in sufficient detail to allow the MPO (or TOOT) to perform a regional 

emissions analysis. This consultation process pursuant to this rule shall be 

initiated by TOOT, or the MPO, where one exists; 

(ii) In the case of any such regionally significant project that has not been disclosed 

to the MPO and other interested agencies participating in the consultation 

process in a timely manner, such regionally significant project shall not be · 

considered to be included in the regional emissions analysis supporting the 

current conformity determination and not to be consistent with the motor vehicle 

emissions budget in the applicable implementation plan or interim budget. 

11. Transportation model development: 

12. 

An interagency consultation process in accordance with the interagency consultation 

procedures outlined in this rule shall be undertaken for the design, schedule, and funding 

of research and data collection efforts related to regional transportation model 

development (such as household/ travel transportation surveys), to be initiated by MPOs 

(or TOOT, if applicable). 

Responding to significant comments: 

If the written response to a significant comment does not adequately. address the 

commenting agency's concerns, further consultation is to be conducted. If a regularly 

scheduled meeting is to be held within a reasonable time frame of the receipt of the 

significant comment, it should be made a part of that meeting's agenda and information 

on the issue will be forwarded to all involved agencies. If necessary, discussion and 

resolution of the significant comment will be considered a reason to convene a special 

meeting with the commenting agency as the requester and the agenda consisting of the 

significant comment. 

(g) Resolving conflicts: 

Any conflict among State agencies or between State agencies and the MPO shall be escalated to 

the Governor if the conflict cannot be resolved by the heads of the involved agencies. All 

agencies involved shall make every effort to resolve any differences, including personal meetings 

between the heads of such agencies or their policy-level representatives, to the extent possible. 

The appeal process described herein shall apply only to MPO (or TOOT) approved conformity 

determinations on the transportation plan, TIP, or projects (including project-level determinations), 

including any documents directly related to determinations of conformity and conflicts between 

state agencies or between one or more state agency(ies) and the MPO. 

1. In the event that the MPO or TOOT determines that every effort has been made to 

addressTAPCD concerns and no further progress is possible, the MPO or TOOT shall 

notify the Director of TAPCD in writing to this effect. The. memorandum shall delineate 

each unresolved issue to be appealed, and shall include, at a minimum: 

(i) 

(ii) 

(iii) 

SS-7037 (January, 2009) · 

State the legal basis of the issue/conflict and steps taken to resolve the conflict. 

Relevant reference material needed to facilitate review and mediation of the 

conflict, including all relevant portions of state and federal law and regulations, 

conformity requirements, and any other relevant documents. 

A description of all reasonable alternatives and supporting data and justification 

for each alternative. Quantify and document the need for the recommended 

13 
alternative consistent with the Clean Air Act of 1990 et seq. and the applicable 

state and federal laws and regulations. 

(iv) Explain the consequences of not reaching a resolution. 

2. If conflicts concerning conformity determinations cannot be resolved by the interagency 

consultation procedures, then the State air agency shall notify the agency or agencies 

involved in the conflict of its intent to escalate the conflict resolution to the office of the 

Governor. 

3. The fourteen (14) calendar day window shall commence: 

(i) On the date that the Technical Secretary of TAPCD and head of the agency or 

agencies involved in the conflict officially agree that the conflict cannot be 

resolved, or 

(ii) One or more agencies other than TAPCD request the start of the fourteen (14) 

day clock on a specified date, after notifying all other agencies involved of their 

intent, and TAPCD agrees. · 

4. If TAPCD does not contact the office of the Governor within the fourteen (14) calendar 

day window, then the issue in conflict is considered to be resolved in favor of the agency 

in conflict with TAPCD. 

5. The Governor may delegate his or her role, but not to the head or staff ofTAPCD, TDOT, 

a state transportation commission or board, or an MPO. 

6. TAPCD shall notify involved parties of the final decision by the office of the Governor. 

7. In the case of interstate nonattainment areas, if the conflict involves agencies outside · 

Tennessee, and the conflict cannot be resolved by the affected agency heads, tl. 

conflicts may be resolved in a manner mutually agreed to by the parties involved. 

(h) Public participation: 

1. Each agency subject to conformity shall provide the general public a window of 

opportunity no less than thirty (30) days to review and comment on new conformity 

determinations before formal action (approval or endorsement by an executive committee 

of the MPO, or where no MPO exists, TDOT management, for submission to FTA/FHWA 

for their finding) is taken on all transportation plans, TIPs and STIPs, consistent with 

these requirements and those of 23 CFR §450.316(a). A comment period of no less than 

fourteen (14) days will be made available to the public on amendments to conformity 

determinations and associated documents. TAPCD and local air agencies shall offer the 

public the same opportunity to comment before final action on SIPs which may have a 

direct or indirect effect upon the motor vehicle emissions budget for an area subject to 

conformity. The notification process shall include, at a minimum, public notices and 

submittals to public depositories. In addition, all public ·comments that specifically 

address known plans for a regionally significant project, which is not receiving FHWA or 

FTA funding or approval, have not been properly reflected in the emissions analysis 

supporting a proposed conformity determination for a transportation plan or TIP, must be 

responded to, in writing, within thirty (30) days of the end of the comment period. 

2. The public participation procedure defined in part 1 of this subparagraph shall not be 

construed as superseding public involvement procedures already in effect for agencies 

subject to the conformity consultation process, such as the MPOs' citizen involvement 

process, the Uniform Administrative Procedures Act (TCA 4-5-101 et seq.), thP . 

Tennessee Sunshine Law (TCA 8-44-101 et seq.), or any other established proce.-· -. 

which already meets or exceeds these standards. In addition, this subparagraph does 

not apply to project-level conformity determinations subject to NEPA where a NEPA 

public participation process exists. 

SS-7037 (January, 2009) 14 
: 

3. The public or ariy interested party may also inspect any of the documents related to the 

conformity process upon request; any charges imposed on the public for inspection or 

copying documents related to the conformity process shall be consistent with (or no 

greater than) the fee schedule contained in 49 CFR §7.43.
