§176.350. Initial Release Abatement Measures

Unless directed in writing to do otherwise by OSFM, owners or operators shall perform the following release abatement measures:

 

a)         Remove as much of the regulated substance from the UST as is necessary to prevent further release to the environment;

 

b)         Visually inspect any aboveground release or exposed belowground release and prevent further migration of the released substance into surrounding soils and groundwater;

 

c)         Continue to monitor and mitigate any additional fire and safety hazards posed by vapors or free product that have migrated from the UST excavation zone and entered into subsurface structures (such as sewers or basements); and

 

d)         Remedy hazards posed by contaminated soils that are excavated or exposed as a result of release confirmation, site investigation, abatement or corrective action activities. If these remedies include treatment or disposal of soils, the owner or operator shall comply with applicable State and local requirements.
