Section 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 ground water, 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 board. 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 subsections 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 subsection 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 ground water, 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.
