CH. 76 UNDERGROUND STORAGE OF REGULATED SUBSTANCES
(c) The Agency shall cause the owner of any previously-approved AST, which is discovered to have been improperly abandoned in-place, to remove the improperly abandoned AST and any soil and/or groundwater contamination found to be caused by a release from the AST; and shall be mitigated by the owner as soon as reasonably possible, but not to exceed one eighty (180) calendar days, or as may be deemed reasonable by the Administrator. This shall not apply to any ASTs that previously received written approval to be abandoned in-place, and were properly abandoned in- place.
(d) Any AST discovered to have been abandoned in-place without written approval from the Agency shall be removed as soon as reasonably possible, but not to exceed one hundred eighty (180) calendar days, or for a longer time as may be deemed reasonable by the Administrator, and any soil and/or groundwater contamination found to be caused by a release from the AST shall be mitigated as soon as reasonably possible. If ownership of the AST is unknown, uncertain, and disputed, the current owner of the land where the AST has been found shall be responsible for removal of the AST and required mitigation. Nothing herein, however, shall prohibit the owner of such land from pursing any remedies available in equity or at law against the party which previously owned and abandoned in-place the AST in question if such party is subsequently identified.
