Kan. Admin. Regs. § 28-29-1607 - Land-spreading; operating and management requirements
Each operator that conducts land-spreading shall meet all of the following requirements:
(a)
Storage of drilling waste. The operator shall store the drilling waste at the
site of generation in pits permitted by the KCC or in tanks until the drilling
waste is transported to the disposal site. The operator may store drilling
waste in sealed tanks at the disposal site for no more than 24 hours before the
drilling waste is land-spread.
(b)
Time frame for land-spreading. The operator shall comply with the following:
(1) Complete the land-spreading within the
approval period specified in K.A.R. 28-29-1601 ; and
(2) notify the appropriate KCC district
office at least 48 hours before land-spreading.
(c) Composition of drilling waste. The
operator shall land-spread only if the composition of the drilling waste meets
the following requirements:
(1) The chloride
concentration of the drilling waste is less than 10,000 parts per million
(ppm). The operator may blend drilling waste that has a chloride concentration
greater than 10,000 ppm with drilling waste that has a chloride concentration
of less than 10,000 ppm to create a combined drilling waste that has a chloride
content of less than 10,000 ppm.
(2) The NORM level in the drilling waste, as
identified through any subsequent sampling and analysis, remains consistent
with the information submitted with the application. If the observed NORM level
in the drilling waste is more than 370 Bq/kg (10 pCi/g), the operator shall
immediately cease land-spreading and shall notify the KCC within two business
days. The operator shall evaluate the condition of the land-spreading site to
determine any potential site impact and perform all corrective measures
required by the KCC or the department to protect human health or safety or the
environment. The operator shall not conduct any additional land-spreading at
the site unless authorized by the KCC.
(d) Weather restrictions. The operator shall
not conduct land-spreading if at least one of the following conditions exists
at the disposal site:
(1) Precipitation is
occurring or, according to national weather service predictions, has a greater
than 50 percent probability of occurring within 24 hours after the
land-spreading is completed.
(2)
The soil cannot readily absorb the moisture content of the drilling waste due
to soil moisture content or frozen soil, or for any other reason.
(e) Land-spreading requirements.
The operator shall land-spread according to all of the following requirements:
(1) The operator shall land-spread at a rate
no greater than the land-spreading rate calculated using the land-spreading
worksheet.
(2) The operator shall,
as much as possible, land-spread so that the drilling waste has a uniform
thickness over the disposal site.
(3) The operator shall limit the average
thickness of the drilling waste to the calculated depth, unless the calculated
depth is more than two inches. If the calculated depth is more than two inches,
the operator shall limit the average thickness of the drilling waste to no more
than two inches.
(4) The operator
shall land-spread in a manner that prevents the drilling waste from either
ponding on the disposal site or running off the disposal site or into buffer
zones.
(5) The operator shall
land-spread according to the methods described in the approved application. If
any deviation from the approved methods occurs and the deviation could result
in a chloride loading rate greater than the rate approved by the KCC, the
operator shall report the deviation to the KCC by the end of the next business
day.
(f) Incorporation.
The operator shall incorporate the drilling waste into the soil if the
precipitation in the county in which the disposal site is located averages more
than 25 inches per year. The following counties and any county located east of
these counties shall be designated as meeting this condition: Jewell, Mitchell,
Lincoln, Ellsworth, Rice, Reno, Kingman, and Harper.
The operator shall incorporate the drilling waste into the soil using standard agricultural methods, including discing, plowing, knifing, and shallow injection. This procedure shall be performed as soon as possible and not later than 48 hours after land-spreading is completed. The operator shall incorporate the drilling waste into the soil according to the methods described in the approved application.
(g) Land restoration. The operator shall take
steps to restore the land-spreading area as described in the approved
application.
