1 Session 3: When Do You Do Conformity

Session 3: When Do You Do Conformity

FHWA Transportation Conformity and CMAQ Workshop Summer 2004

2 New Nonattainment Areas

New Nonattainment Areas

CAA and conformity rule provide a one-year grace period for newly designated nonattainment areas After one year: conforming plan and TIP must be in place subject to conformity frequency requirements

3 When will conformity apply for the new air quality standards

When will conformity apply for the new air quality standards

Conformity applies one year after the effective date of EPA’s nonattainment designation for a given standard June 15, 2005: Conformity applies for most 8-hour ozone areas (e.g., except EACs) 1-hour ozone standard will be revoked Jan/Feb 2006: Conformity applies for PM2.5

4 When is the first conformity determination required

When is the first conformity determination required

First conformity determination for the new standards must be completed: for metropolitan and donut areas, by the end of the one-year grace period or plan/TIP conformity will lapse for isolated rural areas, by the first FHWA/FTA project phase approval (no lapse will occur in these areas, however, since these areas do not have plans/TIPs) conformity determinations can be completed voluntarily during the grace period effective date of conformity determinations can be during the grace period

5 Does DOT have to make a determination by the end of the grace period

Does DOT have to make a determination by the end of the grace period

Yes, both the MPO and DOT must make plan and TIP conformity determinations by the end of the grace period In order to avoid a lapse

6 What requirements apply for other standards during grace period

What requirements apply for other standards during grace period

Until the standard is revoked 1-hour areas must continue to comply with the rule’s 1-hour requirements and existing 1-hour SIP budgets 1-hour conformity determinations required: for plan or TIP updates or amendments to satisfy triggers (e.g., 18 months after a 1-hour budget is found adequate) to satisfy other frequency requirements Conformity for other pollutants continues as applicable

7 Do all determinations during grace period have to address new standard

Do all determinations during grace period have to address new standard

No, conformity to a new air quality standard cannot be required during its grace period An area could decide to not address a new standard during the grace period, even if it was addressed in a previous determination during the grace period However, by the end of the grace period a DOT plan/TIP conformity determination must be made for new standard to avoid lapse

8 When does 3-year conformity clock start for new standards

When does 3-year conformity clock start for new standards

Refresher: A new conformity determination and regional emissions analysis required at least every 3 years PM2.5: 3-year clock starts on date of of first plan/TIP determination and regional emissions analysis, even if DOT’s determination done during PM2.5 grace period “First” determination = what is in place at end of grace period

9 When does 3-year conformity clock start for new standards

When does 3-year conformity clock start for new standards

8-hour ozone: 3-year clock starts on date of either: DOT’s first conformity determination, based on a new regional emissions analysis for 8-hour ozone, even if DOT’s determination done during grace period, or DOT’s last 1-hour conformity determination, based on a new analysis, in the case where an 8-hour area relies on a previous 1-hour analysis for all or a portion of the first 8-hour determination

10 Can an 8-hour area rely on a previous 1-hour analysis

Can an 8-hour area rely on a previous 1-hour analysis

Yes, if the requirements of 93.122(g) are met: Analysis must apply to the plan and TIP; Be applicable to the 8-hour boundary; and Meet all of the requirements of 93.118 or 93.119 e.g., The previous analysis for the budget test must include a regional analysis for the 8-hour attainment year.

11 Examples: 3-year clock in 8-hour ozone areas

Examples: 3-year clock in 8-hour ozone areas

Example 1: DOT makes a plan/TIP conformity determination based on a new regional emissions analysis: DOT determination made on June 1, 2005 3-year clock starts on June 1, 2005

12 Examples: 3-year clock in 8-hour ozone areas

Examples: 3-year clock in 8-hour ozone areas

Example 2: DOT makes a plan/TIP conformity determination based on the previous regional emissions analysis: Previous DOT determination made on September 1, 2004 DOT determination made on June 1, 2005 3-year clock starts on September 1, 2004
