Section 170.560  Reporting of Suspected Releases

Owners or operators of UST systems shall report to Illinois Emergency Management Agency within 24 hours and follow the procedures in Section 170.580 for any of the following conditions:

a)         The discovery by owners, operators or others of released regulated substances at the UST site or in the surrounding area (such as the presence of free product or vapors in soils, basements, sewer or utility lines or nearby surface water);

b)         Unusual operating conditions observed by owners or operators (such as the erratic behavior of product dispensing equipment, the sudden loss of product from the UST system or an unexplained presence of water in the tank), unless system equipment is found to be defective but not leaking and is immediately repaired or replaced; or

c)         Monitoring results from a release detection method required under Section 170.510 or 170.520 that indicate a release may have occurred, unless:

1)         The monitoring device is found to be defective and is immediately repaired, recalibrated or replaced, and additional monitoring does not confirm the initial result; or

2)         In the case of monthly inventory control, a second month of data does not confirm the initial result; however, the 24-hour reporting requirement remains in effect.
