Form R – Toxic Chemical Release Inventory (TRI)
A comprehensive annual report that documents the use, manufacturing, and disposal of certain toxic chemicals. The EPA requires that all manufacturers annually assess if they have exceeded the reporting thresholds for the previous calendar year; and file a report for those chemicals. The EPA has increased the enforcement for this.

Storm Water Annual Inspection Report

There are exceptions if the facility's storm water discharges to a combined sewer system (such as large areas of Chicago).
