Section 13-10 - Special permit conditions for hazardous waste wells
Universal Citation: WY Code of Rules 13-10
Current through September 21, 2024
All Class I hazardous waste wells permitted under this chapter shall be subject to the special permit conditions listed in this section in addition to the conditions applicable to all Class I well permits in Section 9 of this chapter.
(a) All hazardous waste injection permits issued under this chapter shall include the following conditions:
(i) A requirement that
the operator shall maintain a casing/tubing annulus pressure that exceeds the
operating injection pressure, unless the administrator determines that such a
requirement might harm the integrity of the well. The fluid used in the
casing/tubing annulus shall be noncorrosive, and shall contain a corrosion
inhibitor.
(ii) A requirement that
the operator shall follow special procedures when wastes have the potential to
react with the injection formation or to generate gases either during or after
injection. These procedures may take the form of special permit conditions that
limit the temperature or pH of the injected waste and require the operator to
follow procedures necessary to assure that pressure imbalances which might
cause a backflow or blowout do not occur.
(iii) A requirement that the operator shall
install, maintain, and use continuous recording devices to monitor the
injection pressure, flow rate, temperature, of injected fluids and pressure on
the casing/tubing annulus, and shall install and use automatic alarm and
shut-off systems designed to shut down the well when pressures, flow rates, and
other parameters approved by the administrator exceed the range specified in
the permit.
(iv) A requirement that
the operator have a trained operator onsite at all times the well is
operating.
(v) A requirement that
if an automatic alarm or shutdown is triggered, the operator shall immediately
investigate and identify as early as possible, the cause of the alarm or
shutdown. If, upon such investigation, or if required monitoring indicates,
that the well is lacking in mechanical integrity, the operator shall:
(A) Cease all injections of waste fluids
immediately;
(B) Take all necessary
steps to determine the presence or absence of a leak; and
(C) Notify the administrator within
twenty-four (24) hours after the alarm or shutdown, using procedures and
criteria listed in paragraph 20 of Section 9(d)(xx) in this chapter.
(D) The operator shall restore and
demonstrate, to the satisfaction of the administrator, mechanical integrity,
prior to resuming injection activities.
(vi) A requirement that whenever the operator
obtains evidence that there may have been a release of injected wastes into an
unauthorized zone, regardless of whether or not an automatic alarm or shutdown
was triggered, the operator shall:
(A)
Immediately cease all injection activities;
(B) Notify the administrator pursuant to the
procedures outlined in paragraph 20 of Section 9 in this chapter. In addition
to the information required by paragraph 20, the operator shall also include,
as part of the written submission, a proposed remedial action plan, designed to
minimize the adverse impact of the unauthorized release;
(C) Comply with the requirements of any
remedial action plan approved by the administrator; and
(D) Where the unauthorized release is into a
Class I aquifer, as classified under Chapter VIII, Quality Standards for
Wyoming Groundwaters, Water Quality Rules and Regulations, which is currently
serving as a water supply, the operator shall place a notice, describing the
unauthorized release and the actions taken, in a newspaper of general
circulation in the locality of the release.
(E) The administrator may allow the operator
to resume injection prior to completion of cleanup operations if the operator
demonstrates, to the satisfaction of the administrator, that the injection
activity will not endanger any Underground Source of Drinking Waters.
(vii) A requirement that the
operator notify the administrator and obtain his approval prior to conducting
any well workover.
(viii) A
requirement that the operator comply with the following federal regulations
contained in 40 CFR 264 or applicable state hazardous waste regulations:
(A) Identification numbers;
(B) Recordkeeping and reporting for
manifested wastes;
(C) Manifest
discrepancies;
(D) Operating record
requirements;
(E) Annual reporting
requirements and unmanifested waste reports; and
(F) Personnel training
requirements.
(ix) When
abandonment is completed, the operator must submit to the administrator
certification by the operator and certification by an independent registered
professional engineer that the facility has been closed in accordance with the
specifications detailed in the closure plan in Section 16 of this
chapter.
