1 99 W Sixth St Page 2 diameter than the originally drilled borehole shall be excavated around the outside of the well casing to a depth of 3 feet below the ground surface, and the well casing shall then be cut off 6 inches above the bottom of this excavation, and removed. The grout used to seal the well shall then be topped off and allowed to spill over into the excavation and fill it for a thickness of one foot to form a 'mushroom cap' over the top of the cut casing. • If 'nested' wells were installed at the site and need to be destroyed by overdrilling, an auger larger than the original auger must be used and centered on the deepest casing (which is off-center in the original borehole). The auger needs to be sized sufficiently to reach out and remove all well casings, screens, filter packs, and grout sealant installed during construction. • All groundwater displaced to the surface during grout installation shall be pumped out of the excavation and containerized for proper disposal. • Any wells located offsite require updated access agreements and/or encroachment permits to be submitted with the EHD Well Destruction Permit Application._ Deadline for submittal of the work plan is February 28, 2013. After the EHD has approved the work plan you may submit an EHD Well Destruction Permit Application along with the appropriate fees. Current fees are: $375.00 per permit, (one permit per parcel) plus $125.00 per each well on the parcel that is to be destroyed. A nested well is considered to be one well.
