Guidance for Submission of Surface Water Data
For Consideration in Preparing the 2014 Integrated Report on Illinois Water Quality, including the List of Clean Water Act Section 303(d) Impaired Waters
The Illinois Environmental Protection Agency (Illinois EPA) is in the process of considering all applicable surface-water data (biological, chemical and physical) and information to help identify:
This information will be considered in preparing the 2014 Section 305(b) and 303(d) reports on Illinois water quality (due April 1, 2014), as required by the federal Clean Water Act. Section 305(b) of the Clean Water Act requires states to prepare a water quality inventory of its surface waters every two years. Section 303(d) requires states to prepare a list of impaired surface waters for which comprehensive water quality studies (i.e., Total Maximum Daily Load studies) must be prepared to help guide restoration and other management efforts. This list, commonly called the "303(d) List," represents a subset of all impaired waters, as some impaired waters do not require a Total Maximum Daily Load study.
Illinois EPA is interested in surface-water quality data or other information, regardless of whether it suggests that the water body is in "good", "fair", or "poor" condition. This guidance provides information on how and when surface-water data/information can be submitted to Illinois EPA for consideration.
What To Submit
Data packages will be accepted through July 15, 2012. Data packages submitted after this date will be considered in the preparation of similar reports subsequent to the 2014 report.
Quality assurance and quality control considerations are especially important; knowing the quality of the data/information helps minimize the potential for errors in distinguishing "good" waters from impaired waters. To be considered by Illinois EPA, submitted data/information must meet the following requirements:
Data packages sent to the Illinois EPA must include:
