Air Quality Analysis for I-271 Widening Project Available for Comment

Garfield Heights
(Tuesday, March 18, 2014) - The Ohio Deaprtment of Transportation (ODOT) has proposed the widening of I-271from the existing I-271/I-480 interchange, just north of the Summit County Line to the I-271/I480/SR 422 interchange in Cuyahoga County - a total distance of 5.6 miles. This section of I-271 was originally built in the early 1960s with sections resurfaced in 1983 and 2007-2008. The Northeast Ohio Areawide Coordinating Agency (NOACA) completed a Major Investment Study (MIS) along this corridor in March 2002. ODOT then initiated the IR-271 Southbound Freeway Improvement Study in March 2009 to study two safety locations.

The purpose of the CUY-271-0.00 improvement project is to relieve congestion along I-271 to provide safe and efficient travel. These improvements will be done in a phased approach, with this specific project beginning just south of the I-271/I-480 Southern System Interchange, running north to the I-480 Westbound Northern System Interchange. This section is approximately six miles in length and includes an overlap of I-271 and I-480 travel streams in both the northbound and southbound directions.

The particulate matter (PM) 2.5 Hotspot Analysis for CUY/SUM-271-0.00/14.87 PID 80418 is being made available for public review and comment.  It is available here:

Comments are due by April 18, 2014 and can be made to Thomas Sorge, District 12 Environmental Specialist at 216-584-2086, tom.sorge@dot.state.oh.us, or 5500 Transportation Blvd. Garfield Heights, Ohio 44125.

What does the project involve?  The widening of I-271from the existing I-271/I-480 interchange, just north of the Summit County Line to the I-271/I480/SR 422 interchange in Cuyahoga County - a total distance of 5.6 miles.  

What is a PM2.5 Hotspot Analysis?  A PM2.5 Hotspot Analysis is an estimation of likely future localized PM2.5 pollutant concentrations and a comparison of those concentrations to the National Ambient Air Quality Standards.

Why it was done?  A PM2.5 Hotspot Analysis was prepared because the project was deemed a project of air quality concern by the resource agencies because of the new lanes, high traffic volumes, and truck percentages.
 

Why it is being made available for public review and comment?  The PM2.5 Hotspot Analysis is being made available for public review and comment because USEPA’s Transportation Conformity Guidance for Quantitative Hot-spot Analyses in PM2.5 and PM10 Nonattainment and Maintenance Areas requires agencies to provide an opportunity for public review and comment (40 CFR 93.105(e).
