After remaining out of service for five (5) years, the Director may call for the well to be properly abandoned. 6. DESTRUCTION OF WELLS 6.1. When a well no longer functions as originally designed, or cannot appropriately function in place of another design, or has fallen into such a state of disuse or disrepair that it may become a . source of impairment to the ground water quality, constitutes a safety hazard, or found to be abandoned, it must be destroyed under a well destruction permit. 6.2. All oil residue from oil lubed pumps shall be removed and disposed of properly. 6.3. SEALING REQUERE1vIENT: 6.3.1. When a well is to be destroyed, the interior of the casing shall first be cleared to eliminate any obstructions which might interfere with effective sealing procedures. 6.3.2. The open well may then be filled with approved filler material from the bottom up to 100 feet below the ground surface, however a deeper seal may be required by the Director according to site specific requirements. The approved sealing material (see Section 4.7.3.) shall be installed from the filler material to the top of the casing. 6.3.3. If there is no annular seal, or the integrity of the seal or the well is unknown, or the well is gravel packed, the casing shall be perforated upward beginning just above the filler material to the surface. Grout shall be applied above the approved filler material in such a manner that the grout will be forced out of the perforated holes, forming a barrier to the vertical movement of water. 6.3.4. Where the maximum depth of a well being destroyed is less than 100 feet, and there is no standing water, the well shall be sealed from the bottom to its total depth with grout, bentonite, or a minimum of five (5) sack mix of concrete not greater than 1/4" aggregate, or as specified by the Director. 6.3.5. Approved bentonite may be allowed to freefall up to 200 feet in a well destruction if the space will allow no bridging, and if done in accordance with manufacturer's specification. 6.3.6. For the protection of the seal, and to facilitate the future use of the land site, a hole at least one foot larger in diameter than the originally drilled hole shall be excavated 12
