Universal Citation: MS Code of Rules 11-5-2.6-280.62
Current through September 24, 2024
(a) Unless directed to do otherwise by the MDEQ, 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 § 280.52(b) or the closure site
assessment of § 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 § 280.64.
(b) Within 10 days after release confirmation, or within another reasonable period of time determined by the MDEQ, owners and operators must submit a report to the MDEQ summarizing the initial abatement steps taken under paragraph (a) of this rule and any resulting information or data.
