9 Va. Admin. Code § 25-580-330 - Assessing the site at closure or change-in-service
A.
Before permanent closure or a change-in-service is completed, owners and
operators must measure for the presence of a release where contamination is
most likely to be present at the UST site. In selecting sample type or types
(soil or water) and sample location or locations, and measurement methods,
owners and operators must consider the method of closure, the nature of the
stored substance, the type of backfill, the depth to groundwater and other
factors appropriate for identifying the presence of a release. Samples shall be
tested according to established EPA analytical methods or methods approved by
the department. Where the suspected release is a petroleum product, the samples
shall be analyzed for total petroleum hydrocarbons (TPH). The requirements of
this section are satisfied if one of the external release detection methods
allowed in subdivisions 5 and 6 of
9VAC25-580-160
is operating in accordance with the requirements in
9VAC25-580-160
at the time of closure, and indicates no release has occurred.
B. In all cases where a sample or samples are
analyzed, the owner and operator shall submit, along with the amended UST
notification form as required in subdivision 1 of
9VAC25-580-320,
a copy of the laboratory results (including a statement as to the test method
used), a description of the area sampled, and a site map depicting tanks,
piping, and sample location or locations.
C. If contaminated soils, contaminated
groundwater or free product as a liquid or vapor is discovered under subsection
A of this section, or by any other manner, owners and operators must begin
corrective action in accordance with Part VI (9VAC25-580-230 et seq.)
of this chapter.
