On October 19 LADCO issued an RFP to develop exceptional events demonstrations for wildfire smoke impacts on ground-level ozone concentrations in the Great Lakes region. The objective of this project is to determine if there is sufficient evidence to indicate a clear and causal relationship between wildfire smoke and ozone National Ambient Air Quality Standards (NAAQS) violations at ozone monitors in the LADCO region. Analyses for this project will focus on dates that have regulatory significance for the 2020 ozone design values in the Chicago, West Michigan, Southeast Michigan, and Cincinnati ozone nonattainment areas.

The goal of this project is to produce approvable exceptional events demonstration documentation for the LADCO states to submit to U.S. EPA to seek relief from some of regulatory actions under the 2008 and 2015 ozone NAAQS.

LADCO is seeking contractor support on a series of five technical tasks to demonstrate the impacts of wildfire smoke on ground level ozone in the region.


Proposals are due to LADCO on November 2, 2020.


See the LADCO RFPs page for details on this project.
