This report compares monitored SO2 levels at four sites near the Duke Gibson power plant with predicted levels derived from AERMOD. Comparisons were made using both on-site and National Weather Service meteorological data. Data were analyzed comparing monitored and modeled values both in time and not in time. Results indicate a significant over-prediction by AERMOD regardless of how the values are compared.
This document details the current air quality monitoring network and changes planned for 2016
The Indiana Department of Environmental Management (IDEM) has released The States’ View of the Air (2015) report. This report highlights the air quality in counties and cities in the United States. Like a report card, IDEM has graded areas on the state of their air quality under the federal standards for ozone and fine particles.
IDEM is looking for private residential well owners in all 92 counties in Indiana to take part in the statewide Ground Water Monitoring Network. Eligible residential wells will be tested free of charge, and copies of analytical results will be provided at the end of the study. Information about participating, including eligibility requirements, is available on the IDEM Statewide Ground Water Monitoring Network Survey page.

While Indiana urges U.S. EPA to withdraw the proposed rule for multiple reasons as set forth below, the State of Indiana respectfully requests that U.S. EPA take into consideration the technical corrections and comments outlined in the attachments to this letter if it proceeds in finalizing the rule.
