​Portland Area Carbon Monoxide Maintenance Plan

Substitute Transportation Control Measure - Transit
 
Description

The second Portland Area Carbon Monoxide Maintenance Plan, dated Dec. 10, 2004, details measures that ensure the region will continue to meet the national air quality standard for carbon monoxide through 2017. The plan was recently updated.
The plan designates three measures as Transportation Control Measures, which makes them subject to federal transportation conformity rule requirements. Several governmental entities, including DEQ and Metro, determined that the first of these measures should be modified to accommodate the increased cost of diesel fuel during the 2008 recession. The original Transportation Control Measure read as follows:
“Transit Service Increase: Regional transit service revenue hours (weighted by capacity) shall be increased 1.0% per year. The increase shall be assessed on the basis of a 5 year rolling average of actual hours for assessments conducted between 2006 and 2017. Assessments made for the period through 2008 shall include the 2004 opening of Interstate MAX.” [Page 22 of the plan]
In December 2013, the Oregon Environmental Quality Commission rescinded the original transportation control measure and replaced it with the following revised version:
“Transit Service Increase: Regional transit service revenue hours (weighted by capacity) shall be increased 1.0% per year. The increase shall be assessed on the basis of cumulative average of actual hours for assessment conducted for the entire second ten-year Portland Area Carbon Monoxide Maintenance Plan (2007 – 2017). Transit service increase will be assessed on the basis of fiscal year (July 1– June 30) beginning with FY 2008.”
Early in 2014 the Metro Council and U.S. Environmental Protection Agency concurred with the substitute Transportation Control Measure for transit, making it officially effective.
