Effective Redesignation Date: 6/18/97 (62 FR 27204, 5/19/97)

Maintenance Plan - Key Features

• 1990 base year; 1992 attainment year; projections to 2006
• existing measures include FMVCP, summertime RVP of 7.8 psi, major source NSR requiring LAER and offsets, Stage I vapor recovery for Portland and Vancouver, and RACT applied to major industrial sources of VOC
• state and local measures including Stage I and II gasoline vapor recovery requirements, improvements in public transit, transportation demand management measures, and traffic flow improvements
• control measures adopted by the states including the following: (1) hybrid low enhanced vehicles inspection including on-board diagnostics (OBD); (2) expanded vehicle inspection boundary; (3) RVP, fleet turnover, and National Low Emission Vehicles (NLEV); (4) employee commute options; (5) voluntary parking ratio program; (6) transportation control measures; (7) new EPA non-road engine rules; (8) VOC area source rules; (9) industrial permit limit (PSEL) donation program; (10) major NSR/PSD program; (11) source-specific RACT requirements and a gasoline pipeline; (12) public education and incentive program
• annually analyze the ozone air quality monitoring data to verify continued attainment of the ozone standard in accordance with 40 CFR part 50
• continue operating permanent ozone monitoring stations in compliance with 40 CFR part 58
• perform periodic monitoring saturation studies and continue work on a future study which could result in recommendations to add permanent additional monitors; updates will be prepared for 1996, 1999, 2001, 2003, and 2006, and will be submitted to EPA for review
• states will develop the next ten-year maintenance plan (2007-2016) and submit it to EPA by December 31, 2004; revised SIP will provide for maintenance for an additional ten years

Contingency Plan Trigger

• recorded and validated actual violation of ozone NAAQS

Contingency Measures

• NSR requirements for proposed major sources and major modifications in the AQMA (and the area of significant air quality impact) will change. Specifically, requirement to install BACT in the AQMA will be replaced with a requirement for LAER controls and the growth allowance will be eliminated and replaced with offsets.
• in Portland area, rules will be adopted to implement requirements for reformulated gasoline, congestion pricing, or equivalent emission reductio measures
• upon additional violation, area rules in Vancouver will be adopted to implement a remote sensing I/M program or equivalent measure

Schedule

• Changes in NSR requirements will take effect upon validation of a NAAQS violation.
• no additional schedule information given
