Dccr proposes to drill two geotechnical boarings, ms-mw-02d & ms-mw-02s, located at 12 13th st se. Both boarings will be 6 inches in diameter, 02d will be 36 feet deep wioth a foot screened interval starting at 25 feet deep and 02s will be 23 feet deep with a foot screened interval, starting at 13 feet deep. Both will be dirlled with hollow stem auger. No permanent casing will be installed. See idw mangement and attached schematic for additional information. All drill-generated waste will be drummed, solid and liquid. The well shall be covered and protected from surface water drainage and the vertical migration of contaminants and other materials though the well casing and well annulus.

Dccr proposes to drill one geotechnical boring, ms-mw 01, located in 12 13th st se. The boring will be 6 inches in diameter and 2 feet bgs, with a screened interval from 135 to 195 feet bgs, drilled by mud rotary. Permanent stell casing will installed and be socketed feet into p/a and grouted before drilling into the ptx. Msds for drilling mud additives attached. See idw management plan and attached schematics for additiional information. All drillling-generated waste will be drummed, solids and liquids. The well shall be covered and protected from surface water drainage and the vertical migration of contaminants and other materials though the well casting and well annulus.
