Final Summary Report submitted to U.S. EPA Region 5 Air and Radiation Division by ViGYAN Inc., April 1993, estimating and evaluating cancer risks attributed to air pollution in southwest Chicago. The report assesses cancer risk from air pollutants in the southwest Chicago area, prepared under EPA contract for regional air quality and public health assessment.

This 1990 FAA document explains why the Day Night Average Sound Level (DNL) was chosen as the standard metric for measuring airport noise. DNL averages noise exposure over a full 24-hour period, applying a penalty for nighttime flights, and has been adopted by multiple federal agencies—including the EPA, DOT, HUD, and DOD—as the most reliable way to assess how aircraft noise affects surrounding communities. The FAA formally incorporated DNL into federal regulation through FAR Part 150, Airport Noise Compatibility Planning, in 1981.

EPA document EPA 440/5-84-031 establishing ambient water quality criteria for copper, published by the U.S. Environmental Protection Agency Office of Water Regulations and Standards, Washington D.C., pursuant to Section 304(a)(1) of the Clean Water Act of 1977 (P.L. 95-217).

This 1973 U.S. Environmental Protection Agency document establishes scientific criteria for understanding how noise affects public health and welfare, including hearing damage, annoyance, communication interference, and property value loss. Prepared by EPA's Office of Noise Abatement and Control under the Noise Control Act of 1972, it describes cause-and-effect relationships between noise exposure and human health impacts. The criteria laid out in this document were intended to serve as a foundation for developing future noise standards and regulations, though the document itself does not constitute a standard or regulation.
