1. (1) Applicability.

   1. (A) This rule applies to all Environmental Protection Agency (EPA) designated nonattainment and maintenance areas for transportation-related criteria pollutants.

   2. (B) The purpose of this rule is to fulfill the requirement in 40 CFR 51.390(b) to establish a state implementation plan (SIP) revision that includes the following three (3) sections of the federal transportation conformity rule:

      1. 1. 40 CFR 93.105, which addresses

consultation procedures;

1. 2. 40 CFR 93.122(a)(4)(ii), which states

that conformity SIPs must require that written commitments to control measures be obtained prior to a conformity determination if the control measures are not included in a metropolitan planning organization (MPO) transportation plan and transportation improvement program (TIP) and that such a commitment be fulfilled; and

1. 3. 40 CFR 93.125(c), which states that

conformity SIPs must require that written commitments to mitigation measures be obtained prior to a project-level conformity determination and that project sponsors comply with such commitments.

1. (C) Once this rule is approved by the EPA into the Missouri State Implementation Plan, it has full legal effect. Conformity determinations will be governed by these criteria and procedures as well as any applicable portions of the federal conformity rule that are not addressed by the state rule.
2. (D) The Federal Transportation Conformity Rule (for reference) is located at 40 Code of Federal Regulations (CFR) 93.100 through 93.129.

This rule satisfies the requirement of 40 CFR 93.122(a)(4)(ii).

1. K. Written commitments to mitigation

measures for project-level mitigation and control measures must be provided by the project sponsors to the FHWA (or the FTA for transit-related projects) prior to a positive project-level conformity determination and the project sponsors must comply with such commitments. This rule satisfies the requirement of 40 CFR 93.125(c).

1. L. In order to assure the most recent

planning assumptions are in place at the time the conformity analysis begins, the “time the conformity analysis begins” is to be determined by interagency consultation and documented. This point in time should occur at the point at which the MPO 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 and documented in writing and included in publicly available documentation of conformity analysis.

1. M. Consultation will be undertaken

and conducted in accordance with this rule to evaluate events which will trigger new conformity determinations in addition to those 10 CSR 10-5

triggering events established in 40 CFR 93.104, including any changes in planning assumptions that may trigger a new conformity determination. The consultation process pursuant to this rule will be initiated by the FHWA, the EPA, the state air agencies, state transportation agencies, or the MPO.

1. 4. Implementation plans.

   1. A. 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, will be made available to the MPO specified in this rule, as well as state transportation agencies, the FHWA, the FTA, and the EPA in written or electronic form for their review and comment at least thirty (30) days before presentation to the respective state air commissions.

1. B. The state air agencies will also pro-

vide the public a period from the date of announcement to comment on any proposed SIP 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 A. of this paragraph.

1. C. Any proposed revisions to the SIP

will include documentation on methods of analysis, models employed, and purpose of the revision.

1. 5. Other processes.

   1. A. The state air agencies will be

responsible for the process whereby the MPO, the local air agencies, the state transportation agencies, the FHWA, the FTA, and the EPA will study and develop supplementary consultation procedures to identify, evaluate, and address, as needed, specific issues. In the absence of supplementary consultation procedures, the state air agencies will include the following items for discussion during interagency consultation meetings in advance of a conformity determination:

1. (I) Hot-spot analysis methods,

models, and assumptions;

1. (II) Determination of regionally-

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

1. (III) Evaluating when exempt pro-

jects should be treated as non-exempt;

1. (IV) Timely implementation of

TCMs and processing of TCM substitutions;

1. (V) Identifying conformity deter-

mination triggers other than those established in 40 CFR 93.104; and

1. (VI) Methods, models, and

assumptions for regional emissions analysis.

1. B. These supplementary procedures

in subparagraph A. of this paragraph may be specific for the metropolitan area or each nonattainment or maintenance area subject to the conformity rule.

1. C. The state air agencies will conduct

meetings to discuss any supplementary consultation procedure as needed.

1. D. Final document distribution for

conformity determinations associated with plans, TIPs, and STIPs (occasionally, alternate schedules may be used with concurrence by participants)—

1. (I) 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, the state transportation agencies, state air agencies, and any applicable local air agencies. The EPA will respond in writing to the FTA Regional Office and the FHWA Division Office as soon as possible, but not later than thirty (30) days after EPA receives a formal request from FHWA and FTA with all the relevant documentation including the final conformity determination with supporting documentation and data;

1. (II) Comments will be resolved by

the FHWA and the FTA, in concert with the EPA, the MPO, or the state transportation agencies, in their respective areas, as necessary;

1. (III) The FHWA and the FTA will

jointly prepare correspondence to make the conformity finding. Joint conformity findings will be addressed to the MPO with a copy to the state transportation agencies, the EPA, the state air agencies, and any applicable local air agencies. The findings of the FHWA and the FTA together constitute the U.S. Department of Transportation (DOT) conformity findings;

1. (IV) In the event that the MPO or

the state transportation agencies, in their respective areas, wishes to amend the TIP to add projects that are exempt from the conformity analysis requirement, the FHWA or the FTA, or both if necessary, will concur in the amendment and reaffirm the original DOT conformity finding by letter. This reaffirmation letter will reference the date(s) of the original FHWA and FTA findings. In cases where the amendment involves projects that are not exempt, a new conformity analysis and determination will be required, and will, in turn, require a new DOT conformity finding; and

1. (V) Within fifteen (15) days subse-

quent to approval of final documents including transportation plans, TIPs, conformity determinations, applicable implementation plans, and implementation plan revisions, the lead agency will provide copies (electronic copies acceptable) of such documents and supporting information to all affected agencies.

1. E. Generalized hot-spot determina-

tion process. Interagency consultation will be undertaken to evaluate and choose a model(s), associated methods, and planning assumptions to be used in hot-spot analyses. The generalized hot-spot determination process (occasionally, alternate schedules may be used with concurrence by participants) entails—

1. (I) The project sponsor (or the state

transportation agencies 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;

1. (II) If the project is not exempt, the

project sponsor (or the state transportation agencies 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; and

1. (III) If it is determined the project

is a project of air quality concern, the project sponsor (or the state transportation agencies 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 the state transportation agencies or the MPO) will make a PM2.5 hot-spot determination (i.e., projectlevel conformity determination) and request that other stakeholder agencies comment on the conclusions through formal interagency consultation as provided in this rule.

1. F. Regionally-significant projects. For

purposes of regional emissions analysis, the MPO will 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 the state transportation agencies, if applicable) will consider the views of each agency that comments and respond in writing.

1. G. Transportation control measures

(TCMs).

1. (I) For each plan or TIP update, the

agencies specified in subparagraphs (3)(A)2.A., B., C., and D. to participate in consultation will review whether past obstacles to implementation of 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 implementation necessitate revisions to the applicable implementation plan to remove TCMs or substitute TCMs or other emission reduction measures.

1. (II) Where TCMs are to be includ-

ed in an applicable implementation plan, a list of TCMs will be developed by the MPO or the state transportation agencies, or both.

1. H. Exempt projects which may be

nonexempt. The MPO (or state transportation agencies where applicable) will commence consultation regarding potentially exempt projects to (occasionally, alternate schedules may be used with concurrence by participants)—

1. (I) Identify exempt projects as

defined by 40 CFR 93.126 Table 2 and 40 CFR 93.127 Table 3;

1. (II) Identify exempt projects and

categories of exempt projects which should be treated as nonexempt because they may have adverse air quality impacts and determine appropriate air quality analysis methodologies for analyzing such projects;

1. (III) Identify transportation plan,

TIP, and STIP revisions which add or delete exempt projects, as defined in 40 CFR 93.126 Table 2 and 40 CFR 93.127 Table 3; and

1. (IV) The MPO (or the state trans-

portation agencies 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.

1. I. Project disclosure—

   1. (I) The sponsor of any potentially

regionally-significant project, and any agency that is responsible for taking action(s) on any such project, will disclose such project to the state transportation agencies and the MPO in a timely manner. Such disclosure will be made not later than the first occasion on which any Specific to the St. Louis Metropolitan Area

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; the execution of any contract to design or construct; or any approval needed for any facility that is dependent on the completion of the regionally-significant project. To help assure timely disclosure, the sponsor of any potentially regionally-significant project will disclose to the state transportation agencies and the MPO on a schedule prescribed by the state transportation agencies and the MPO, but no less than annually, each project for which alternatives have been identified through the National Environmental Policy Act (NEPA) process and any preferred alternative that may be a regionally-significant project. The consultation process will 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 the state transportation agencies) to perform a regional emissions analysis. This consultation process pursuant to this rule will be initiated by the state transportation agencies and the MPO; and

1. (II) In the case of any such region-

ally-significant project that has not been disclosed to the MPO and the other interested agencies participating in the consultation process in a timely manner, such regionally-significant project will 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.

1. J. Transportation model development.

An interagency consultation process in accordance with the interagency consultation procedures outlined in this rule will 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 MPO.

1. K. Responding to significant com-

ments. 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 regularlyscheduled 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.

1. 6. Resolving conflicts. Any conflict

among state agencies or between state agencies and the MPO will be escalated to the governor if the conflict cannot be resolved by the heads of the involved agencies. All agencies involved will 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 will apply only to the MPO (or the state transportation agencies) 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 (1) or more state agencies and the MPO. Conflicts regarding SIPs should be appealed to the respective state air commissions.

1. A. In the event that the MPO or the

state transportation agencies determine that every effort has been made to address the state air agencies’ concerns and no further progress is possible, the MPO or the state transportation agencies will notify the directors of the respective state air agencies in writing to this effect. The memorandum will delineate each unresolved issue to be appealed and will include, at a minimum:

1. (I) The legal basis of the issue/con-

flict and steps taken to resolve the conflict;

1. (II) 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;

1. (III) A description of all reasonable

alternatives and supporting data and justification for each alternative. Quantify and document the need for the recommended alternative consistent with the Clean Air Act of 1990 et seq. and the applicable state and federal laws and regulations; and

1. (IV) An explanation of the conse-

quences of not reaching a resolution.

1. B. If conflicts concerning conformity

determinations cannot be resolved by the interagency consultation procedures, then the state air agencies will notify the agency or agencies involved in the conflict of its intent to escalate the conflict resolution to the office of the governor within fourteen (14) calendar 10 CSR 10-5

days.

1. C. The fourteen (14)-calendar-day

window will commence—

1. (I) On the date that the directors of

the state air agencies and the head of the agency or agencies involved in the conflict officially agree that the conflict cannot be resolved; or

1. (II) One (1) or more agencies other

than the state air agencies request the start of the fourteen (14)-day clock on a specified date, after notifying all other agencies involved of their intent, and the state air agencies agree.

1. D. If the state air agencies do not con-

tact 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 the state air agencies.

1. E. The governor may delegate his or

her role but not to the head or staff of the state air agencies, the state transportation agencies, a state transportation commission or board, or an MPO.

1. F. The state air agencies will notify

involved parties of the final decision by the office of the governor.

1. 7. Public participation.

   1. A. Each agency subject to conformity

will 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 for submission to the FHWA and the FTA 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. The state and local air agencies will 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 will 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 and has 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.

1. B. The public participation procedure

defined in subparagraph A. of this paragraph will not be construed as superseding public involvement procedures already in effect for agencies subject to the conformity consultation process, such as the MPO’s citizen involvement process, the Missouri Sunshine Law (Chapter 610, RSMo), or any other established process which already meets or exceeds the requirements of subparagraph (3)(B)7.A. of this rule. In addition, this subparagraph does not apply to project-level conformity determinations subject to NEPA where a NEPA public participation process exists.

1. C. The public or any 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 will be consistent with (or no greater than) the fee schedule contained in 49 CFR 7.43.
