Minimum Surface Casing Requirements
Minimum surface casing requirements for protecting fresh and usable water and to meet alternate #1 on Intent to Drill cards, Form C-1
S=Section, T=Township, R=Range
Wells deeper than 1500 feet and using Alternate I completion shall set a mimimum of 250 feet surface casing in T.11, 12 and 13S-R.17E; 300 feet in all other areas; plus when within 1 mile of nearest Kansas River Valley wall set to elevation 810 m.s.l. in T.11S-R.13E, 790 feet m.s.l. in T.11S-R.14E, 770 feet m.s.l. in T.11S-R.15E, 760 feet m.s.l. in T.11S-R.16E, 750 feet m.s.l. in T.11S-R.17E. All other wells shall use Alternate II completion, Appendix B, Area 3, Eastern Surface Casing order. In all cases, set surface casing through all unconsolidated material plus 20 or more feet into the underlying formation.
For areas in which casing settings are given as sea level datums, topographic maps are available showing surface elevations. These maps may be obtained from the U.S. Geological Survey at Denver, Colorado; Rolla, Missouri and Washington, D.C.; and the State Geological Survey, Lawrence, Kansas.
