PURPOSE: This rule reflects the requirements of the federal regulations in 40 CFR part 124, with modifications and additional requirements established by the Revised Statutes of Missouri. This rule establishes the requirements for public notice and public participation in the issuance, denial, modification, and revocation of hazardous waste management facility permits, appeal hearings, variance petitions, and closure and post-closure activities. This rule also specifies procedures for the issuance, modification, and revocation of resource recovery facility certifications and the issuance and revocation of transporter licenses.

1. (1) The regulations set forth in 40 CFR part 124, July 1, 2024, as published by the Office of the Federal Register, National Archives and Records Administration, Superintendent of Documents, Pittsburgh, PA 15250-7954, are incorporated by reference. Except as provided otherwise in this rule, the substitution of terms set forth in 10 CSR 25-3.260(1)(A) apply in this rule, in addition to any other modifications established in paragraph (1)(A)2. of this rule. Where conflicting rules exist in 10 CSR 25, the more stringent rules control. (Comment: This section has been organized so that Missouri requirements analogous to a particular lettered subpart in 40 CFR part 124 are set forth in the corresponding lettered subsection of section (1) of this rule. For example, the general program requirements in 40 CFR part 124 subpart A, with Missouri modifications, are found in subsection (1)(A) of this rule.)

   1. (A) This subsection sets forth requirements that correspond to those requirements in 40 CFR part 124 subpart A.

      1. 1. Purpose and scope. This subsection contains procedures

for the review, issuance, class 3 or department-initiated modification, total modification, or revocation of all permits issued pursuant to sections 260.350 through 260.433, RSMo. This subsection also contains procedures for the denial of a permit, either in its entirety or as to the active life of a hazardous waste management facility or unit, under 40 CFR 270.29, as incorporated in 10 CSR 25-7.270. Interim status is not a permit and is covered by specific provisions in 10 CSR 25-7.265 and 10 CSR 25-7.270. Class 1 or class 2 permit modifications, as defined in 40 CFR 270.42 as incorporated in 10 CSR 25-7.270, are not subject to the requirements of this subsection.

1. 2. Definitions. In addition to the definitions given in 40

1. A. “Draft permit” means a document prepared under

paragraph (1)(A)6. of this rule indicating the department’s tentative decision to issue, deny, modify in part or in total, revoke, or reissue a “permit.” A notice of intent to revoke, as discussed in subparagraph (1)(A)5.D. of this rule, and a notice of intent to deny, as discussed in subparagraph (1)(A)6.B. of this rule, are types of draft permits. A denial of a request for modification, total modification, or revocation of a permit, as discussed in subparagraph (1)(A)5.B. of this rule, is not a type of “draft permit”;

under section 260.400, RSMo;

1. C. “Permit application” means the U.S. Environmental

Protection Agency standard national forms for applying for a permit, including any additions, revisions, or modifications to the forms; or forms approved by the U.S. Environmental Protection Agency for use in Missouri, including any approved modifications or revisions. It also includes the information specified by the department under 40 CFR 270.14–270.29, as incorporated into 10 CSR 25-7.270;

1. D. “Public hearing” means any hearing on a tentative

decision at which any member of the public is invited to give oral or written comments;

1. E. “Revocation” means the termination of a permit;
2. F. “Schedule of compliance” means a schedule of

remedial measures in a permit, including an enforceable sequence of interim requirements (for example, actions, operations, or milestone events) leading to compliance with sections 260.350 through 260.433, RSMo;

1. G. “Total modification” means the revocation and

reissuance of a permit;

   1. A. Any person who requires a permit shall complete,

sign, and submit to the department a permit application for each permit required under 40 CFR 270.1, as incorporated in 10 CSR 25-7.270. Permit applications are not required for permits by rule per 40 CFR 270.60, as incorporated in 10 CSR 25-7.270. The department shall not begin the processing of a permit until the applicant has fully complied with the permit application requirements for that permit, as provided under 40 CFR 270.10 and 270.13, as incorporated in 10 CSR 25-7.270. Permit applications shall comply with the signature and certification requirements of 40 CFR 270.11, as incorporated in 10 CSR 25-7.270(2)(B)1., and 10 CSR 25-7.270.

1. B. Reserved.
2. C. The department shall review for completeness

every permit application. Each permit application submitted by a new facility should be reviewed for completeness by the department within thirty (30) days of its receipt. Each permit application submitted by an existing facility should be reviewed for completeness by the department within sixty (60) days of its receipt. Upon completing the review, the department will notify the applicant in writing whether the permit application is complete. If the permit application is incomplete, the department will list the information necessary to make the permit application complete. When the permit application is for an existing facility, the department will specify, in the notice of deficiency, a date for submitting the necessary information. The department will notify the applicant that the permit application is complete upon receiving the required information. After the permit application is complete, the department may request additional information from an applicant, but only as necessary to clarify, modify, or supplement previously submitted material. Requests for such additional information will not render a permit application incomplete.

1. D. If an applicant fails or refuses to correct deficiencies

in the permit application, the permit may be denied and enforcement actions may be taken under the applicable statutory provisions of sections 260.350 through 260.433, RSMo.

one (1) type of environmental permit from the state, the applicant may request, or the department may offer, a unified permitting schedule that covers the timing and order to obtain such permits, as provided in section 640.017, RSMo, and 10 CSR 1-3.010.

1. 4. Reserved.
2. 5. Modification, total modification, or revocation of

permits.

1. A. Permits may be modified in part or in total, or revoked,

either at the request of the permittee or of any interested person or upon the department’s initiative. However, permits may only be modified or revoked for the reasons specified in 40 CFR 270.41 or 40 CFR 270.43, as incorporated in 10 CSR 25-7.270. All requests shall be in writing and shall contain facts and reasons supporting the request.

1. B. If the department decides the request is not justified,

a brief written response giving a reason for the decision shall be sent to the person requesting the permit modification and to the permittee. Denial of a request for modification, in part or in total, or revocation of a permit is not subject to public notice, comment, or hearing, and is not appealable under section (2) of this rule.

1. C. Tentative decision to modify.

   1. (I) If the department tentatively decides to modify

a permit in part or in total, a draft permit incorporating the proposed changes will be prepared according to paragraph (1)(A)6. of this rule. The department may request additional information and, in the case of a partial permit modification, may require the submission of an updated permit application. In the case of a total permit modification, the department will require the submission of a new permit application.

1. (II) When a permit is partially modified under this

paragraph, only the conditions being modified are reopened. All other conditions of the original permit remain in effect for the duration of the existing permit. When a permit is totally modified under this paragraph, the entire permit is reopened just as if the permit had expired and was being reissued. During any total modification, the permittee complies with all conditions of the existing permit until a new, final permit is issued.

1. (III) “Class 1 and class 2 permit modifications” as

defined in 40 CFR 270.42, as incorporated in 10 CSR 25-7.270, are not subject to the requirements of this paragraph.

1. D. If the department tentatively decides to revoke a

permit, the department will issue a notice of intent to revoke. A notice of intent to revoke is a type of draft permit and follows the same procedures as any draft permit decision prepared under paragraph (1)(A)6. of this rule.

1. B. If the department tentatively decides to deny the

permit application, a notice of intent to deny shall be issued. A notice of intent to deny is a type of draft permit and follows the same procedures as any draft permit decision prepared under this paragraph. If the department’s final decision under paragraph (1)(A)15. of this rule is that the tentative decision to deny the permit application was incorrect, the department shall withdraw the notice of intent to deny and prepare a draft permit under this paragraph.

1. C. Reserved.
2. D. If the department tentatively decides to prepare a

draft permit, the department will prepare a draft permit that contains the following information:

The applicant shall have ten (10) days to review the draft permit for nonsubstantive drafting errors. The department shall make the applicant’s changes to the draft permit within ten (10) days of receiving the applicant’s review and then submit the draft permit for public comment. The applicant may waive the opportunity to review the draft permit prior to public notice.

1. C. Concurrent with the notice under subparagraph

(1)(B)2.B. of this rule, the department will place the permit application and any supporting documents in a location accessible to the public in the vicinity of the facility or at the department’s office as identified in the notice.

1. 3. Information repository.

   1. A. Applicability. The requirements of this paragraph

apply to all applicants seeking hazardous waste management facility permits.

1. B. The department shall assess the need, on a case-by-

case basis, for a local information repository. When assessing the need for a local information repository, the department will consider a variety of factors, including the level of public interest, the type of facility, and the presence of an existing repository. If the department determines, at any time after submittal of a permit application, that there is a need for a local repository, then the department will notify the facility that it must establish and maintain a local information repository.

1. C. The information repository shall contain all documents,

reports, data, and information deemed necessary by the department to fulfill the purposes for which the repository is established. The department will have the discretion to limit the contents of the repository.

1. D. The information repository shall be located and

maintained at a location chosen by the facility. If the department finds the location unsuitable for the purposes and persons for which it was established, due to problems with the location, hours of availability, access, or other relevant considerations, the department will specify a more appropriate location.

1. E. The department will specify requirements the

applicant must meet for informing the public about the local information repository. At a minimum, the department will require the applicant to provide a written notice about the information repository to all individuals on the facility mailing list.

1. (2) Appeal of Final Decision.

   1. (A) For purposes of this section, a final permit decision means the issuance, denial, partial or total modification, or revocation of a permit. The requirements of this section apply to final permit decisions, closure plan approvals, post-closure plan approvals, and any condition of a final permit decision or approval.
   2. (B) The applicant or any aggrieved person may appeal to have the matter heard by the Administrative Hearing Commission. To initiate the appeal, the aggrieved party must follow the procedure established in sections 260.395.11 and 621.250, RSMo. Written petitions must be filed within thirty (30) days after the date the final permit decision or approval was mailed or the date it was delivered, whichever was earlier. If the written petition is sent by registered or certified mail, the petition will be deemed filed on the date it was mailed. If the written petition is sent by any other method, the petition will be deemed filed on the date it is received by the Administrative Hearing Commission. The written petition describes the grounds for the appeal and the appeal is limited to issues raised during the public comment period and not resolved in the final permit decision or approval to the applicant’s or aggrieved person’s satisfaction. Issues included in the written petition outside those raised during the public comment period are not considered; however, the Administrative Hearing Commission may consider an appeal of a condition in the final permit decision or approval that was not part of the draft permit or proposal and therefore could not have been commented on during the public comment period.
   3. (C) Any appeal under this section is a contested case and is conducted under section 260.400, RSMo.

   4. (D) Any party described in subsection (2)(G) of this rule may petition the Administrative Hearing Commission for an interlocutory order staying the effectiveness of a final permit decision, a closure plan approval, a post-closure plan approval, or any condition of a final permit decision or approval which is subject to an appeal, until the Missouri Hazardous Waste Management Commission enters its final order upon the appeal. At any time during the proceeding, the applicant may apply to the Administrative Hearing Commission for relief from a stay order previously issued.

      1. 1. In determining whether to grant a stay or relief from

a stay, the Administrative Hearing Commission will consider the likelihood that the petition will eventually succeed on the merits, the potential for harm to the applicant, business, industry, public health, or the environment if the requested stay or relief is or is not granted, and the potential magnitude of the harm.

1. 2. Any decision concerning a petition for a stay or re-

lief from a stay is not considered a contested case or a final order and is made by a majority of the sitting quorum of the Administrative Hearing Commission.

1. 3. The stay of any final permit decision pending appeal

to the Administrative Hearing Commission has the effect of continuing the effect and enforceability of any existing permit until the Missouri Hazardous Waste Management Commission issues a final order upon the appeal, unless the stay is lifted sooner by the Administrative Hearing Commission. During the appeal proceeding, the stay of any condition of a final permit decision pending appeal does not relieve the applicant of complying with all conditions of the final permit decision not stayed.

1. 4. No petition for a stay order or relief from a stay order

shall be presented to the Administrative Hearing Commission on less than ten (10) days’ notice to all other parties to the proceeding.

1. (E) A timely written petition of appeal stays the effectiveness of a final permit revocation decision. If a timely written petition of appeal is not filed, the final permit revocation becomes effective thirty (30) days after the department signs the decision.
2. (F) Any public notice of appeals, including the time, date, and place of the appeal hearing, will be given by the Administrative Hearing Commission in accordance with section 260.400, RSMo.

3. (G) The participants in an appeal hearing shall be—

   1. 1. The department;
   2. 2. The applicant;
   3. 3. Any aggrieved person filing a timely written petition of

appeal; and

1. 4. Any person who files a timely application for interven-

tion and is granted leave to intervene of right or permissive intervention. Any person desiring to intervene in an appeal shall file with the Administrative Hearing Commission, an application to intervene according to the procedures of Rule 52.12, Supreme Court Rules of Civil Procedure.

1. A. The application to intervene shall state the interests

of the intervener, the grounds upon which intervention is sought, and a statement of the position which the intervener desires to take in the proceeding. The intervener shall serve a copy of the application to intervene on each of the parties to the proceeding as determined under part (1)(A)10.C.(II) of this rule.

1. B. The Administrative Hearing Commission or duly ap-

pointed hearing officer will grant or deny the application to intervene pursuant to Rule 52.12, Supreme Court Rules of Civil Procedure. The Administrative Hearing Commission or hearing officer may condition any grant of intervention as the circumstances may warrant.

1. (H) A tape recording or written transcript of the appeal hearing shall be made available to the public.

1. (3) Transporter License.

   1. (A) Issuance or Denial of a Transporter License.

      1. 1. Upon receipt of a complete application for a transporter

license, the department will determine whether the application conforms to the requirements of sections 260.385 and 260.395, RSMo, and 10 CSR 25-6.263. The department will notify the applicant of its decision to issue, with or without conditions, or deny the license. If the license is denied, the department will specify the reasons for the denial. No license will be issued until the fees specified in section 260.395.1, RSMo, have been paid.

1. 2. The procedure for appealing a license issuance, denial,

or any condition of a license is the same as the procedure for appealing a final permit decision under section (2) of this rule.

1. (B) Revocation of a Transporter License.

   1. 1. Transporter licenses may be revoked for the reasons

specified in sections 260.395.3, 260.410.3, and 260.410.4, RSMo, or for failure to comply with sections 260.395.1(2) and 260.395.1(3), RSMo.

1. 2. The department may initiate proceedings to revoke a

transporter license. If the department proposes to revoke a transporter license, it will send a notice of intent to revoke by certified mail to the licensee, specifying the provisions of sections 260.350–260.433, RSMo, 10 CSR 25-6.263, the conditions of the license or the provisions of an order issued to the licensee that the licensee has violated, the manner in which the licensee misrepresented or failed to fully disclose relevant facts, or the manner in which the activities of the licensee endanger human health or the environment or are creating a public nuisance.

1. 3. The procedure for appealing a license revocation is the

same as the procedure for appealing a permit revocation under section (2) of this rule. A timely written petition for appeal stays the effectiveness of a license revocation. If a timely written petition for appeal is not filed, the revocation is effective thirty (30) days after the department signs the revocation decision.

1. (4) Variances.

   1. (A) Applicability. According to section 260.405.1, RSMo, unless prohibited by any federal hazardous waste management act, the Hazardous Waste Management Commission may grant individual variances from the requirements of sections 260.350 to 260.433, RSMo, whenever it is found, upon presentation of adequate proof, that compliance will result in an arbitrary and unreasonable taking of property or in the practical closing and elimination of any lawful business, occupation, or activity, in either case without sufficient corresponding benefit or advantage to the people. The commission will not consider any petition for variance that would permit the occurrence or continuance of a condition that unreasonably poses a present or potential threat to the health of humans or other living organisms. The department may require any petitioner for a variance to submit mailing lists and mailing labels to accomplish the public notice requirements of this section.
   2. (B) Evaluation. Upon receipt of any petition for a variance, the department will evaluate the petition to determine whether the request is substantive or non-substantive based upon the effect of the proposed variance on facility operations, types of waste, type and volume of hazardous waste management units, location of facility, public interest, and compliance history. Variances from generator or transporter requirements will be deemed non-substantive provided all conditions of section (3) of this rule are met.

   3. (C) Substantive Variance. If a variance petition is deemed substantive, the department will—

      1. 1. Upon receipt—

         1. A. Mail a notice to all record owners of real property

located within one (1) mile of the outer boundaries of the facility, the highest elected official of the county, and the highest elected official of the city, town, or village having jurisdiction over the area where the facility is located; and

1. B. Issue a news release to the media and publish a legal

notice in a newspaper of general circulation serving the area where the facility is located;

1. 2. Within sixty (60) days of receipt—

   1. A. Prepare a recommendation as to whether the variance

should be granted, granted with conditions, or denied;

1. B. Submit the recommendation to the Missouri

Hazardous Waste Management Commission;

1. C. Notify the petitioner of the recommendation;
2. D. Publish a legal notice regarding the recommendation

in a newspaper of general circulation serving the area where the facility is located; and

1. E. Mail a notice regarding the recommendation to all

record owners of real property adjoining to the facility, the highest elected official of the county, and the highest elected official of the city, town, or village having jurisdiction over the area where the facility is located; and

1. 3. Request a formal hearing before the Missouri Hazardous

Waste Management Commission or a duly appointed hearing officer on the variance petition and the department’s recommendation, as provided in section 260.400, RSMo.

1. (D) Non-Substantive Variance. If a variance petition is deemed non-substantive, the department will comply with paragraph (4)(C)2. of this rule. The Missouri Hazardous Waste Management Commission will hold a formal hearing as provided in section 260.400, RSMo, if requested by the petitioner. A request for a formal hearing may also be made by any aggrieved person if the department’s recommendation is to grant the variance with or without conditions. Any request by the petitioner or aggrieved person for a formal hearing shall be made in writing within thirty (30) days of the date the legal notice regarding the recommendation is published.
2. (E) Final Decision. If no formal hearing is requested, the Missouri Hazardous Waste Management Commission shall make a decision on the variance at a public meeting held no earlier than thirty (30) days from the date the legal notice regarding the recommendation was published.

3. (F) Hearing Procedures. Any hearings under this section are a contested case pursuant to section 260.400 and Chapter 536, RSMo. The participants are the department, the petitioner, any aggrieved person who requests a formal hearing, and any person who files a timely application for intervention and is granted leave to intervene. Any person desiring to intervene shall file an application to intervene with the Missouri Hazardous Waste Management Commission secretary within thirty (30) days from the date the legal notice regarding the recommendation is published.

   1. 1. The application to intervene shall state the interests of

the intervener, the grounds upon which intervention is sought, and a statement of the position that the intervener desires to take in the proceeding. The intervener shall serve a copy of the application to intervene on each of the parties listed in subsection (4)(F) of this rule.

1. 2. The Missouri Hazardous Waste Management Commis-

sion or duly appointed hearing officer will grant or deny the application to intervene pursuant to Rule 52.12, Supreme Court Rules of Civil Procedure. The Missouri Hazardous Waste Management Commission or hearing officer may condition any grant of intervention as the circumstances may warrant.

1. (G) If the applicant fails to comply with the terms and conditions of the variance as specified by the Missouri Hazardous Waste Management Commission, the variance may be revoked or modified by the commission after a formal hearing held after no less than thirty (30) days’ written notice. The department will notify all persons who will be subjected to greater restrictions if the variance is revoked or modified and each person who requested notice from the department.
