Sec.  280.65  Investigations for soil and ground-water cleanup.



    (a) In order to determine the full extent and location of soils 

contaminated by the release and the presence and concentrations of 

dissolved product contamination in the ground water, owners and 

operators must conduct investigations of the release, the release site, 

and the surrounding area possibly affected by the release if any of the 

following conditions exist:

    (1) There is evidence that ground-water wells have been affected by 

the release (e.g., as found during release confirmation or previous 

corrective action measures);

    (2) Free product is found to need recovery in compliance with Sec.  

280.64;

    (3) There is evidence that contaminated soils may be in contact with 

ground water (e.g., as found during conduct of the initial response 

measures or investigations required under Sec. Sec.  280.60 through 

280.64); and

    (4) The implementing agency requests an investigation, based on the 

potential effects of contaminated soil or ground water on nearby surface 

water and ground-water resources.

    (b) Owners and operators must submit the information collected under 

paragraph (a) of this section as soon as practicable or in accordance 

with a schedule established by the implementing agency.
