              Containing Petroleum or Hazardous Substances
 
Sec. 280.62  Initial abatement measures and site check.

    (a) Unless directed to do otherwise by the implementing agency, 
owners and operators must perform the following abatement measures:
    (1) Remove as much of the regulated substance from the UST system as 
is necessary to prevent further release to the environment;
    (2) Visually inspect any aboveground releases or exposed belowground 
releases and prevent further migration of the released substance into 
surrounding soils and ground water;
    (3) 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);
    (4) 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 and operator must comply with 
applicable State and local requirements;
    (5) Measure for the presence of a release where contamination is 
most likely to be present at the UST site, unless the presence and 
source of the release have been confirmed in accordance with the site 
check required by Sec. 280.52(b) or the closure site assessment of 
Sec. 280.72(a). In selecting sample types, sample locations, and 
measurement methods, the owner and operator must consider the nature of 
the stored substance, the type of backfill, depth to ground water and 
other factors as appropriate for identifying the presence and source of 
the release; and
    (6) Investigate to determine the possible presence of free product, 
and begin free product removal as soon as practicable and in accordance 
with Sec. 280.64.
    (b) Within 20 days after release confirmation, or within another 
reasonable period of time determined by the implementing agency, owners 
and operators must submit a report to the implementing agency 
summarizing the initial abatement steps taken under paragraph (a) of 
this section and any resulting information or data.
