In
each case of drilling or redrilling, the distance from any well hole
to any occupied structure shall be a minimum of six hundred feet (600’),
unless permittee obtains written consent from the owners of said occupied
structure and furnishes said written consent to the code enforcement
administrator prior to issuance of said permit, but in no event shall
a well be drilled closer than four hundred feet (400’) to a
structure. No well shall be drilled within one thousand feet (1,000’)
of the property line of any school in the Katy Independent School

is hereby declared a nuisance for any person to conduct any drilling
operation or to construct any storage tank or tanks within one thousand
feet (1,000’) of the property line of any school of the Katy
Independent School District or any hospital, convalescent home or
nursing home located either within or outside the city limits.
(Ordinance 2599, sec. III, adopted 11/11/13)

operating limits. On all lines of one thousand (1,000) psi or more,
a second safety shut-in device shall be installed on the line.
(p)
Pressure relief valves.
Two (2) pressure relief valves

annoying substances or effects are emitted therefrom which can be
eliminated or diminished by the use of modern and approved types of
equipment and silencers.
(b)
At
any drill site, the operation of oilfield, drilling, or production
equipment shall not generate an A-weighted noise level which, when
combined with the ambient noise level, will produce a combined noise

in the area more than one thousand feet (1,000’) from any occupied
structure. Each tank shall be equipped with flame arresters and shall
be so constructed and maintained as to be vapor-tight. Each tank or

he may deem necessary to ensure the public safety and to ensure compliance
with the terms of this article.
(1999 Code, sec. 4.229)
If a well is placed in production, it shall be inspected periodically
by the code enforcement administrator in accordance with the requirements
of this article. A notification of status change from producing well
to abandoned well shall become necessary for any well which has not
produced, or which has not been used for subsurface injection into
the earth of oil or gas for a period of nine (9) months, unless permission
to hold said well for a longer period of time is obtained from the
state railroad commission. The operator shall upon request of the
code enforcement administrator furnish verification of production
for the purposes of this section.

ninety (90) days after the completion of drilling operations or abandonment
of further drilling, the derrick shall be removed from the drill site.
Well abandonment shall be in accordance with the requirements of all
applicable laws and ordinances. Upon such well abandonment, the permittee
shall restore the property as nearly as possible to its original condition
and shall remove all concrete foundations, oil-soaked soil, and debris.
All holes or depressions shall be filled to the natural surface.
(2)
The
code enforcement administrator shall determine that the drill site
and all facilities pertinent thereto have been restored to their original
