Illinois Commerce Commission On Its Own Motion -vs- Northern Illinois Gas Company d/b/a Nicor Gas Company: Reconciliation of revenues collected under gas adjustment charges with actual costs prudently incurred.
This document describes Illinois Maintenance Plan for the Illinois portion of the Chicago ozone nonattainment area. A Maintenance Plan is required before the area can be redesignated from nonattainment to attainment of the 8-hour ozone National Ambient Air Quality Standard (NAAQS) promulgated in 1997. This document also provides technical information required to support a redesignation request. This revision incorporates motor vehicle emissions estimates developed using the U.S. EPAs MOVES model.
This document is the description of the methods used to compile the 2002 base year inventory for particulate matter. It includes CO, NH3, NOx, PM10, PM2.5, SO2 and VOM emissions for point, area, on-road mobile, off-road mobile and biogenic emissions for the entire State of Illinois.
This document describes Illinois Maintenance Plan for the Illinois portion of the St. Louis ozone nonattainment area (NAA), hereafter referred to as the Metro-East NAA. A Maintenance Plan is required before an area can be redesignated from nonattainment to attainment of a National Ambient Air Quality Standard (NAAQS). This document provides technical information required to support a request to redesignate the Metro-East NAA to attainment of the 1997 8-hour ozone NAAQS. This revision incorporates motor vehicle emissions estimates developed using the U.S. EPAs MOVES model.
This technical support document addresses the economic reasonableness and technological feasibility of further regulation to reduce VOM emissions from consumer and commercial products, AIM coatings, and aerosol coating products by limiting the solvent content in these products, or the amount of ozone formed when these products are used.
In order to reduce lead emissions in the Chicago and Granite City nonattainment areas, and to attain and maintain the NAAQS in these areas, Illinois EPA is proposing to limit lead emissions from nonferrous metal production facilities in lead NAAs. The purpose of this document is to provide technical support for the proposed regulation, and includes a description of the affected sources and their emissions, emission limits and work practices required by the proposed regulation, and an analysis of the technical feasibility of achieving those limits and implementing those practices at the affected sources.Illinois EPA is proposing to limit lead emissions from affected emission units charging lead bearing materials through the use of pollution control devices. Illinois EPA is also proposing various measures to limit fugitive lead emissions from these sources to the greatest degree practicable.
