Sec.  280.62  Initial abatement measures and site check.

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.
