Evaluating Ozone Precursor Emissions Reductions in the Great Lakes Region 

The objective of this project was to identify and evaluate candidate emissions controls for reducing NOx and VOC emissions in the LADCO region. Under contract to LADCO, Ramboll, Inc. identified NOx and VOC emissions control measures that are feasibly applicable to sources in the LADCO region. Ramboll evaluated the measures on the basis of emissions mass reduction and cost effectiveness. They investigated all inventory sectors, with particular attention paid to under-controlled sources of NOx and VOC. 

The project resulted in a priority list of potential emissions reduction options, in terms of costs/ton and total NOx or VOC emissions mass, for all anthropogenic sources of NOx and VOC in the 2016v1 U.S. emission inventory.

The results in these reports are based on estimates of the emissions and available controls, and not all controls in place may have been accounted for in this review.

NOx Emissions Controls for Stationary Sources in the Great Lakes Region 

Under contract to LADCO, Ramboll, Inc. identified and evaluated nitrogen oxides (NOx) emissions control options for industrial point sources (i.e., non-electrical generation unit (non-EGU) sources). The potential control measures may be considered by state and local agencies to reduce emission of ozone precursors. Emission reductions in addition to those resulting from on-the-books (OTB) regulations may be necessary to meet state implementation plan (SIP) requirements and to demonstrate attainment of ozone National Ambient Air Quality Standards (NAAQS). 

The results in these reports are based on estimates of the emissions and available controls, and not all controls in place may have been accounted for in this review.
