Lake Michigan Ozone Study

Project Description
The Lake Michigan Ozone Study (LMOS) is a multi-year cooperative
interstate and federal effort that is seeking a regional
solution to the ozone nonattainment problem in the Lake
Michigan area, which includes portions of Illinois, Indiana,
Michigan, and Wisconsin. A key objective of LMOS is to provide
the Lake Michigan States with a technically credible
photochemical modeling system that can be used in developing a
regional emissions control strategy. Initial efforts involved
the conduct of a field program during the summer of 1991,
analyses of the data collected in the field study, the
development of gridded, day-specific emissions estimates for
four ozone episodes, application of a prognostic model to
provide meteorological inputs, adaptation of the Urban Airshed
Model (UAM-V) to the study area, evaluation of model
performance, and the conduct of model sensitivity studies. The
EPA has approved usage of the LMOS modeling system for
developing revisions to the SIPs for the fo! ur Lake Michigan
States.

The Lake Michigan Ozone Control Program (LMOP) is also a
cooperative interstate and federal effort that represents the
regulatory continuation of LMOS. The initial goal of LMOP was to
develop an effective regional control strategy that will provide
for attainment of the ozone National Ambient Air Quality
Standard (NAAQS) by the statuatory dates, and to submit
individual State Implementation Plans that reflect this regional
strategy. The long-term goal is to provide a mechanism for the
Lake Michigan States to work together to ensure successful
implementation of the regional strategy, and if appropriate,
revision of the regional strategy, to achieve attainment (and
maintenance) of the NAAQS.
