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 minimum of 275 feet surface casing plus shall set to the base of the Kansas City Group in T.7, 8, 9, 10, 11 and 12S-R.22E; T.9, 10, 11 and 12S-R.21E; T.11 and 12S-R.20E; and T.8, 9 and 10S-R.23E plus when within 1 mile of nearest Kansas River Valley wall set to elevation of 710 feet mean sea level in T.12S-R.20E, 700 feet m.s.l. in T.12S-R.21E, and 690 feet m.s.l. in T.12S-R.22E. All other wells shall use Alternate II rules, 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.
