Sec.  226.22  Prohibition of pollution.

    (a) All operators, contractors, drillers, service companies, pipe 
pulling and salvaging contractors, or other persons, shall at all times 
conduct their operations and drill, equip, operate, produce, plug and 
abandon all wells drilled for oil or gas, service wells or exploratory 
wells (including seismic, core and stratigraphic holes) in a manner that 
will prevent pollution and the migration of oil, gas, salt water or 
other substance from one stratum into another, including any fresh water 
bearing formation.
    (b) Pits for drilling mud or deleterious substance used in the 
drilling, completion, recompletion, or workover of any well shall be 
constructed and maintained to prevent pollution of surface and 
subsurface fresh water. These pits shall be enclosed with a fence of at 
least four strands of barbed wire, or an approved substitute, stretched 
taut to adequately braced corner posts, unless the surface owner, user, 
or the Superintendent gives consent to the contrary. Immediately after 
completion of operations, pits shall be emptied and leveled unless 
otherwise requested by surface owner or user.
    (c) Drilling pits shall be adequate to contain mud and other 
material extracted from wells and shall have adequate storage to 
maintain a supply of mud for use in emergencies.
    (d) No earthen pit, except those used in the drilling, completion, 
recompletion or workover of a well, shall be constructed, enlarged, 
reconstructed or used without approval of the Superintendent. Unlined 
earthen pits shall not be used for the continued storage of salt water 
or other deleterious substances.
    (e) Deleterious fluids other than fresh water drilling fluids used 
in drilling or workover operations, which are displaced or produced in 
well completion or stimulation procedures, including but not limited to 
fracturing, acidizing, swabbing, and drill stem tests, shall be 
collected into a pit lined with plastic of at least 30 mil or a metal 
tank and maintained separately from above-mentioned drilling fluids to 
allow for separate disposal.
