Wyoming Administrative Code › Agency 020 - Environmental Quality, Dept. of › Sub-Agency 0011 - Water Quality › Chapter 13 - CLASS I HW & NON-HW WELLS UNDERGROUND INJECTION CONTROL PROGRAM › Section 13-10 - Special permit conditions for hazardous waste wells

Current through July 13, 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.
