  1. Isolated Rural Areas US EPA Conformity Training Summer 2004 Eddie Dancausse FHWA NC Division 919-856-4330x112 edward.dancausse@fhwa.dot.gov

  2. Outline of this Session • Types of Areas • Metropolitan vs. Isolated Rural Areas • Test Requirements • Regional Emissions Analyses • Flexibility

  3. Refresher: Types of Areas • Isolated rural areas: those nonattainment or maintenance areas which don’t have an MPO and whose projects aren’t part of any MPO’s regional emissions analysis (population less than 50,000) • Metropolitan areas: areas that have an MPO and have a plan/TIP (population of at least 50,000) • “Donut” areas: outside the metropolitan planning boundary but inside the nonattainment/maintenance area boundary

  4. GracePeriod in Isolated Rural Areas • Isolated rural areas have 1-year grace period for new standards • Projects can be approved during grace period without conformity determination • After grace period, new project or project phase approvals require a conformity determination

  5. What actions require conformity? • Isolated Rural Areas: • Conformity only done for FHWA/FTA projects in the nonattainment or maintenance area • Conformity not done on statewide plans and statewide TIPs (STIPs) • Conformity does not change DOT’s requirements for statewide plans and STIPs

  6. Metropolitan Areas: transportation plans and TIPs FHWA/FTA projects Isolated Rural Areas: no plan or TIP FHWA/FTA projects Continued What actions require conformity?

  7. Metropolitan Areas: MPO and US DOT make the plan or TIP conformity determination Project conformity determination prepared by sponsor (e.g., MPO, state DOT) for US DOT conformity determination Isolated Rural Areas: Project conformity determination often prepared by state DOT for US DOT conformity determination Who Does Conformity?

  8. Metropolitan Areas: Subject to frequency requirements for plan/TIP conformity determinations Isolated Rural Areas: Not subject to frequency requirements for plan/TIP conformity determinations (i.e., isolated rural areas do not lapse) Conformity done when an FHWA/FTA project needs approval When and How Often is Conformity Done?

  9. Test Requirements for Isolated Rural Areas (93.109(l)) • 93.110 -- latest planning assumptions • 93.111 -- latest emissions model • 93.112 -- consultation • 93.113(d) -- timely implementation of TCMs • 93.116 -- hot spots • 93.117 -- PM10 and PM2.5 control measures • 93.118 / 93.119 -- budget test or interim emissions test(s)

  10. Refresher: Regional Emissions Analysis • Regional emissions analysis for an isolated rural area must: • include all “regionally significant projects,” including regionally significant non-federal projects (see definition in 93.101) • estimate VMT from entire transportation system including all FHWA/FTA projects (non-regionally significant FHWA/FTA projects must be estimated through reasonable professional practice, 93.122(a)(1)) • cover the transportation planning horizon (generally 20 years)

  11. Metropolitan Areas: FHWA/FTA projects in the plan/TIP and regionally significant non-federal projects plan covers at least 20 years Isolated Rural Areas: projects funded or approved by FHWA/FTA in statewide plan or STIP are grouped together and analyzed with all other regionally significant projects expected in the area over timeframe of the statewide transportation plan (or at least 20 years) Regional Emissions Analysis

  12. Regional Conformity Tests for Years of SIP • Metropolitan and isolated rural areas both demonstrate conformity with the budget test and applicable SIP budgets

  13. Metropolitan Areas: must continue to demonstrate conformity to latest SIP budget(s) Isolated Rural Areas: have flexibility to choose: budget test interim emissions test(s), or demonstrate through modeling used in the SIP that project conforms Regional Test Options after the SIP (93.109(I)(2)(ii))
