1. (a) Owners/operators of all underground storage tank systems must notify PSTD at least fourteen (14) days prior to the removal or permanent closure of underground storage tanks and/or lines by submitting the PSTD scheduling form and receiving confirmation of the scheduled removal from PSTD. If events require a change in the date of removal, PSTD shall be given forty-eight (48) hours notice prior to the new date.
2. (b) An authorized agent of PSTD may be present to observe the removal and to inspect the closed tank system and the surrounding environment prior to backfilling.
3. (c) Tanks and lines must be removed upon closure unless a Commission order grants a variance that allows the tanks and/or lines to be closed in place. Tank systems that are removed from the ground must be transported from the site and whether sold to a scrap dealer or disposed of at an acceptable facility, sufficient holes should be made in the tanks to render the tank(s) unfit for further use. A certificate of destruction must be submitted to PSTD with the UST Closure Report. When scheduling a removal, a site map of where samples are to be taken should be attached to the scheduling form. After closure activities are completed, the excavation must be backfilled no later than seven (7) days upon completion of tank removal. Backfill material shall be earth, gravel, rock, sand or combinations thereof, backfill shall predominate in the finer sizes and present no isolated voids, silt pockets or areas of large stones. Refer to OAC 165:29-3-65 when backfilling. Exceptions to backfilling within seven (7) days may be made when a new tank system is scheduled to be installed in the same tank pit.
4. (d) The Licensed UST Remover must be on the job site during all removal activities, beginning with break-out of concrete. This includes Licensed UST Remover presence during cutting and removing concrete over any part of the tank system.
5. (e) Photos must be taken of tank(s), line(s) and soil at removal. In the event there is a hole in tank(s) or line(s), further photographic evidence is required. If tank(s), line(s) or excavated soil show evidence of a release, photos of the apparent release must be taken that indicate the release source.
