On July 14, 2021 LADCO issued an RFP to conduct gridded air quality modeling and analysis to support ozone National Ambient Air Quality Standards (NAAQS) attainment demonstration modeling for Southeast Michigan (SEMI). The project objectives are as follows:

  • To provide a 1.3-km resolution ozone model simulation of the SEMI region for the base year 2016 that is acceptable to the US EPA based on model performance statistics.
  • To improve emission inventories by the addition of undercounted formaldehyde (HCHO) and volatile chemical product (VCP) sources.
  • To examine the role of added HCHO and VCP emissions in improving ozone model performance and response to control strategies.
  • To assess the impacts of selected emissions control strategies on simulated ozone in 2023 and on the corresponding relative response factors (RRFs).

The goal of this study is to identify ozone reduction strategies that will demonstrate and lead to attainment of the 2015 ozone NAAQS for the SEMI nonattainment area.

LADCO is seeking contractor support on a series of six technical tasks to design and execute episodic and ozone season simulations of 2016 and projections to 2023 using a gridded chemistry-transport model. The contractor will interpret the results of emissions control scenarios to quantify how surface ozone concentrations in SEMI respond to reductions in ozone precursor emissions. 

Proposals are due to LADCO on August 13, 2021 and we expect to award the project September 1.

See the LADCO RFPs page for details on this project.
