Sec.  280.50  Reporting of suspected releases.





    Owners and operators of UST systems must report to the implementing 

agency within 24 hours, or another reasonable time period specified by 

the implementing agency, and follow the procedures in Sec.  280.52 for 

any of the following conditions:

    (a) The discovery by owners and 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 and 

utility lines, and nearby surface water).

    (b) Unusual operating conditions observed by owners and 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; and,

    (c) Monitoring results from a release detection method required 

under Sec.  280.41 and Sec.  280.42 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 inventory control, a second month of data does 

not confirm the initial result.
