Permit Actions
(40 CFR § 144.51(f), 40 CFR § 124.5, 40 CFR § 144.38, 40 CFR § 144.39, 40 CFR § 144.40, 40 CFR § 144.41)
This permit may be modified, revoked and reissued, or terminated either at the request of any interested person (including the Permittee) or upon the Director of DWQ’s initiative. However,
permits may only be modified, revoked and reissued, or terminated for the reasons specified in sections a) and b) below. All requests shall be in writing and shall contain facts and
reasons supporting the request. The filing of a request for a permit modification, revocation and re-issuance, or termination on the part of the Permittee, does not stayany permit condition.
This permit may be transferred according to the procedures given in section d).
Modification or Revocation and Reissuance of Permit
When the Director receives any information (e.g., inspects the facility, receives information submitted by the Permittee as required in the permit, receives a request for modification
or revocation and reissuance, or conducts a review of the permit file), the Director may determine whether or not one or more of the causes listed in paragraphs (1) and (2) of this section
for modification or revocation and reissuance or both exist.If cause exists, the Director may modify or revoke and reissue the permit accordingly, subject to the limitations of paragraph
(3) of this section and may request an updated application if necessary.When a permit is modified, only the conditions subject to modification are reopened.If a permit is revoked and
reissued, the entire permit is reopened and subject to revision and the permit is reissued for a new term.If cause does not exist under this section a) or under section c) for minor
modifications, the Director shall not modify or revoke and reissue the permit.If a permit modification satisfies the criteria for minor modifications in section c) the permit may be
modified without a draft permit or public review.Otherwise, a draft permit must be prepared and other procedures in 40 CFR § 124, incorporated by reference into the Utah UIC Program
rules (hereafter referred to as “40 CFR § 124”), must be followed.
Causes for modification.For Class V wells the following may be causes for revocation and reissuance, or, if the Permittee requests or agrees, modification.
Alterations.There are material and substantial alterations or additions to the permitted facility or activity that occurred after permit issuance which justify the application of permit
conditions that are different or absent in the existing permit.
Information.The Director has received information.Permits other than for Class II and Class III wells may be modified during their terms for this cause only if the information was not
available at the time of permit issuance (other than revised regulations, guidance, or test methods) and would have justified the application of different permit conditions at the time
of issuance.For UIC area permits, this cause shall include any information indicating that cumulative effects on the environment are unacceptable.
New regulations.The standards or regulations on which the permit was based have been changed by promulgation of new or amended standards or regulations or by judicial decision after
the permit was issued.Permits for Class V wells may be modified during their permit terms for this cause only as follows:
(i) For promulgation of amended standards or regulations, when:
(A) The permit condition requested to be modified was based on a regulation in 40 CFR § 146; and
(B) Environmental Protection Agency (EPA) has revised, withdrawn, or modified that portion of the regulation on which the permit condition was based; and
(C) A Permittee requests modification in accordance with 40 CFR § 124.5 within ninety (90) days after Federal Register notice of the action on which the request is based.
(ii) For judicial decisions, a court of competent jurisdiction has remanded and stayed EPA promulgated regulations if the remand and stay concern that portion of the regulations on which
the permit condition was based, and a request is filed by the Permittee in accordance with 40 CFR § 124.5 within ninety (90) days of judicial remand.
Compliance schedules.The Director determines good cause exists for modification of a compliance schedule, such as an act of God, strike, flood, or materials shortage or other events
over which the Permittee has little or no control and for which there is no reasonably available remedy. See also 40 CFR § 144.41(c).
Causes for modification or revocation and reissuance.The following are causes to modify or, alternatively, revoke and reissue a permit:
Cause exists for termination under 40 CFR § 144.40, and the Director determines that modification or revocation and re-issuance is appropriate.
The Director has received notification (as required in the permit, see 40 CFR § 144.41(d)) of a proposed transfer of the permit.A permit also may be modified to reflect a transfer after
the effective date of an automatic transfer (40 CFR § 144.38(b)) but will not be revoked and reissued after the effective date of the transfer except upon the request of the new Permittee.
A determination that the waste being injected is a hazardous waste as defined in 40 CFR § 261.3 either because the definition has been revised, or because a previous determination has
been changed.
Facility siting.Suitability of the facility location will not be considered at the time of permit modification or revocation and reissuance unless new information or standards indicate
that a threat to human health or the environment exists which was unknown at the time of permit issuance.
Termination of Permit
The Director may terminate a permit during its term, or deny a permit renewal application for the following causes:
Noncompliance by the Permittee with any condition of the permit;
The Permittee's failure in the application or during the permit issuance process to disclose fully all relevant facts, or the Permittee's misrepresentation of any relevant facts at any
time; or
A determination that the permitted activity endangers human health or the environment and can only be regulated to acceptable levels by permit modification or termination.
The Director shall follow the applicable procedures in 40 CFR § 124 in terminating any permit under this section.
Minor Modification of Permit
Upon the consent of the Permittee, the Director may modify a permit to make the corrections or allowances for changes in the permitted activity listed in this section, without following
the procedures of 40 CFR § 124.Any permit modification not processed as a minor modification under this section must be made for cause and with 40 CFR § 124 draft permit and public notice

as required in section a).Minor modifications may only:
Correct typographical errors;
Require more frequent monitoring or reporting by the Permittee;
Change an interim compliance date in a schedule of compliance, provided the new date is not more than 120 days after the date specified in the existing permit and does not interfere
with attainment of the final compliance date requirement; or
Allow for a change in ownership or operational control of a facility where the Director determines that no other change in the permit is necessary, provided that a written agreement
containing a specific date for transfer of permit responsibility, coverage, and liability between the current and new Permittees has been submitted to the Director.
Change quantities or types of fluids injected which are within the capacity of the facility as permitted and, in the judgment of the Director, would not interfere with the operation
of the facility or its ability to meet conditions described in the permit and would not change its classification.
Change construction requirements approved by the Director pursuant to 40 CFR § 144.52(a)(1) (establishing UIC permit conditions), provided that any such alteration shall comply with
the requirements of 40 CFR § 144 and 40 CFR § 146.
Amend a plugging and abandonment plan which has been updated under 40 CFR § 144.52(a)(6).
Transfer of Permit
Transfers by Modification.Except as provided in paragraph (2) of this section, a permit may be transferred by the Permittee to a new Owner or Operator only if the permit has been modified
or revoked and reissued under Part II.E.6.a.2.ii, or a minor modification made under Part II.E.6.c.4, to identify the new Permittee and incorporate such other requirements as may be
necessary under the SDWA.
Automatic Transfers.As an alternative to transfers under paragraph (1) of this section, any UIC permit for a well not injecting hazardous waste or injecting carbon dioxide for geologic
sequestration may be automatically transferred to a new Permittee if:
The current Permittee notifies the Director at least 30 days in advance of the proposed transfer date referred to in paragraph (2)(ii) of this section;
The notice includes a written agreement between the existing and new Permittees containing a specific date for transfer of permit responsibility, coverage, and liability between them,
and the notice demonstrates that the financial responsibility requirements of 40 CFR § 144.52(a)(7) will be met by the new Permittee; and
Financial Responsibility. The Permittee, including the transferor of a permit, is required to demonstrate and maintain financial responsibility and resources to close, plug, and abandon
the underground injection operation in a manner prescribed by the Director until the transferor of a permit has received notice from the Director that the Owner or Operator receiving
transfer of the permit, the new Permittee, has demonstrated financial responsibility for the well.
The Director does not notify the existing Permittee and the proposed new Permittee of intent to modify or revoke and re-issue the permit.A modification under this paragraph may also
be a minor modification under section c) – Minor Modification of Permit.If this notice is not received, the transfer is effective on the date specified in the agreement mentioned in
