Non-Point sources have no accountability. IEPA needs to improve the water quality data sets. Sampling Quality Assurance Project Plans are important. Stakeholders need to help IEPA accomplish this. Limited reliable data could lead to failure in developing TMDLs.
Data quality is important.
IEPA needs to create a data summary of each critical waterbody. On the issue of the listing of category of pollutant vs. individual contaminant of concern, parties will need more specific data to begin evaluation work. Existing stream codes on maps are difficult to use to verify your own stream segments. Point source dischargers need advance notification about listing. The existing Facility Planning Area process could help with characterizing runoff in listed watersheds.
