all reasonably available arguments supporting their position by the close of the public comment 

period under 40 CFR 124.10. Any supporting materials which are submitted shall be included in 

full and may not be incorporated by reference, unless they are already part of the administrative 

record in the same proceeding, or consist of State or federal statutes and regulations, EPA 

documents of general applicability, or other generally available reference materials. Commenters

decision on the proposed permit within 30 days after the final hearing. The Director shall issue or 

deny the final permit no later than 15 days from receipt of any findings of fact and decision of the 

Council. The Director shall notify the applicant and each person who has submitted written 

comments or requested notice of the final permit decision. This notice shall include reference to 

the procedures for appealing a decision on a State HWMF permit or for contesting a decision to 

terminate a State HWMF permit. For the purposes of 40 CFR 124.15, a final permit decision 

means a final decision to issue, deny, modify, revoke and reissue, or terminate a permit.

Section 266. STANDARDS FOR THE MANAGEMENT OF SPECIFIC HAZARDOUS 

WASTES AND SPECIFIC TYPES OF HAZARDOUS WASTE MANAGEMENT FACILITIES.

(a) IBR AND EXCEPTIONS. 40 CFR Part 266 and all Subparts are herein 

incorporated by reference as provided in 40 CFR.

(i) For purposes of 40 CFR 266.210 "You" shall be a generator, treater, or 

other handler of low-level mixed waste or eligible NARM (Naturally Occurring and/or Accelerator-
1-20

produced Radioactive Material), otherwise “you” refers to any generator, treater, or handler of 

hazardous waste under these rules.

(b) MILITARY MUNITIONS.

266.202(d) (i) For purposes of RCRA Section 1004(27), a used or fired military 

munition is a waste material, and, therefore, is potentially subject to RCRA corrective action 

authorities under W.S. 35-11-503(d), 40 CFR 264.101(c), or RCRA Sections 3004(u) and (v), and 

3008(h), or imminent and substantial endangerment authorities under W.S. 35-11-115; W.S. 35-

11-503(d); Articles 7 and 9 of the Act or RCRA Section 7003, if the munition lands off-range and 

is not promptly rendered safe and/or retrieved. Any imminent and substantial threats associated 

with any remaining material must be addressed. If remedial action is infeasible, the operator of 

the range must notify the Director in writing and maintain a record of the event for as long as any

threat remains. The record must include the type of munition and its location (to the extent the 

location is known).

266.203(b) (ii) Reinstatement of exemption. If any waste military munition loses its 

exemption under 40 CFR 266.203(a)(1), an application may be filed with the Director for 

reinstatement of the exemption from hazardous waste transportation regulation with respect to 

such munition as soon as the munition is returned to compliance with the conditions of 40 CFR 

266.203(a)(1). If the Director finds that reinstatement of the exemption is appropriate based on 

factors such as the transporter's provision of a satisfactory explanation of the circumstances of 

the violation, or a demonstration that the violations are not likely to recur, the Director may 

reinstate the exemption under 40 CFR 266.203(a)(1). If the Director does not take action on the 

reinstatement application within 60 days after receipt of the application and if the military 

continues to seek reinstatement of the exemption, it is the responsibility of the military to contact 

the Director to establish a mutually-agreeable time line for the Director to address the application.

In reinstating the exemption under 40 CFR 266.203(a)(1), the Director may specify additional 

conditions as are necessary to ensure and document proper transportation to protect human 

health and the environment.

266.203(c) (iii) Amendments to DOD shipping controls. The Department of Defense 

shipping controls applicable to the transport of military munitions referenced in 40 CFR 

266.203(a)(1)(ii), and in effect on November 8, 1995, are the Signature and Tally Record (DD 

Form 1907) and the Motor Vehicle Inspection(Transporting Hazardous Materials) (DD Form 626). 

For shipment by commercial transport the U.S. Government Bill of Lading (GBL) (GSA Standard 

Form 1103) is also required. For shipment by military transport, the following additional controls 

are applicable: DD Single Line Item Release/Receipt Document (DD Form 1348-1A) and the 

Shipping Paper and Emergency Response Information for Hazardous Materials Transported by 

Government Vehicles (DD Form 836). Any amendments to the above Department of Defense 

shipping controls shall not become effective for purposes of 40 CFR 266.203(a)(1) until the 

amended Department of Defense shipping control has been adopted by rule by the DEQ. 

Adoption of an amended Department of Defense shipping control will be contingent on the 

Director’s affirmative finding that the amended shipping control(s) is/are protective of human 

health and the environment. Copies of Department of Defense shipping controls can be obtained 

upon request from the DEQ, 122 West 25th Street, Cheyenne, Wyoming 82009.

266.205(a)(1) (iv) The owner or operator may store only waste military munitions generated 

by the individual facility.

266.205(a)(1) (v) Section 266(b)(iv) of this Chapter does not apply if storage of waste 

military munitions from another facility is the result of an inability to transport the waste military 

munitions for treatment or disposal due to inclement weather or other circumstance as approved 

in writing by the Director.
1-21

266.205(c) (vi) Reinstatement of conditional exemption. If any waste military munition 

loses its conditional exemption under 40 CFR 266.205(a)(1), an application may be filed with the 

Director for reinstatement of the conditional exemption from hazardous waste storage regulation 

with respect to such munition as soon as the munition is returned to compliance with the 

conditions of 40 CFR 266.205(a)(1). If the Director finds that reinstatement of the conditional 

exemption is appropriate based on factors such as the owner's or operator's provision of a 

satisfactory explanation of the circumstances of the violation, or a demonstration that the 

violations are not likely to recur, the Director may reinstate the conditional exemption under 40 

CFR 266.205(a)(1). If the Director does not take action on the reinstatement application within 60 

days after receipt of the application and if the military continues to seek reinstatement of the 

exemption, it is the responsibility of the military to contact the Director to establish a mutuallyagreeable time line for the Director to address the application. In reinstating the conditional 

exemption under 40 CFR 266.205(a)(1), the Director may specify additional conditions as are 

necessary to ensure and document proper storage to protect human health and the environment.

266.205(d)(1) (vii) Waste military munitions that are chemical agents or chemical munitions 

and that exhibit a hazardous waste characteristic or are listed as hazardous waste under 40 CFR 

Part 261, are listed or identified as a hazardous waste and shall be subject to the applicable 

regulatory requirements of the Act.

266.205(e) (viii) Amendments to DDESB storage standards. The DDESB storage 

standards applicable to waste military munitions, referenced in 40 CFR 266.205(a)(1)(iii), are 

DOD 6055.9-STD ("DOD Ammunition and Explosive Safety Standards"), in effect on November 

8, 1995, except as provided in the following sentence. Any amendments to the DDESB storage 

standards shall not become effective for purposes of 40 CFR 266.205(a)(1) until the amended 

Department of Defense DDESB storage standards have been adopted by rule by the DEQ. 

Adoption of amended Department of Defense DDESB storage standards will be contingent on the 

Director’s affirmative finding that the DDESB storage standards are protective of human health 

and the environment.

officers or corporate directors, based on the record before the Director, constitutes evidence that 

the applicant will comply with provisions of the Act and these rules and is fit to obtain a permit.

(i) The Director may determine that the applicant is not fit to obtain a permit 

if the applicant, or any partners, executive officers or corporate directors have:

(A) Misrepresented or concealed any material fact in the permit 

application;

(B) Obtained a permit from the Director by misrepresentation or 

concealment of a material fact;

(C) Been convicted of a felony or pleaded guilty to a felony for 

violations of environmental quality or criminal racketeering laws or regulations within the five (5)

application in compliance with the Act and these rules;

(D) Been adjudicated in contempt of any order of any court enforcing 

laws of any state or the federal government within five (5) years preceding the application for a 

permit.

(ii) In determining whether the applicant is fit under Sections 270(m) and 

270(n) of this Chapter, the Director shall consider: 

(A) The relevance of the offense to the business for which a permit 

is issued;

(B) The nature and seriousness of the offense;

(C) The circumstances under which the offense occurred;

(D) The date of the offense;
1-31

(E) The ownership and management structure in place at the time of 

the offense; 

(F) Evidence of rehabilitation including the applicant's record of 

implementing corrective action, the applicant's cooperation with governmental entities, 

implementation of formal policies and procedures to prevent recurrence, and the discharge of 

individuals or severance of affiliation with parties responsible for the offense.

(o) INTERIM STATUS CORRECTIVE ACTION ORDERS.

RCRA §3008(h)(1) (i) Whenever on the basis of any information the Director determines that 

there is or has been a release of hazardous waste into the environment from a facility authorized 

under 40 CFR 270.70, the Director may issue an order requiring corrective action or such other 

response measure as the Director deems necessary to protect human health or the environment 

or the State may commence a civil action under the Act.

RCRA §3008(h)(2) (ii) Any order issued under Section 270(p) of this Chapter may include a 

suspension or revocation of authorization to operate under 40 CFR 270.70, shall state with 

reasonable specificity the nature of the required corrective action or other response measure, and 

shall specify a time for compliance. If any person named in an order fails to comply with the 

order, the State may initiate a civil action under the Act.

(p) IMMINENT HAZARD.

RCRA §7003(a) (i) Notwithstanding any other provision of the Act, upon receipt of evidence 

that the past or present handling, storage, treatment, transportation or disposal of any waste 

material or hazardous waste may present an imminent and substantial endangerment to public 

health or the environment, the Attorney General may bring suit on behalf of the people of the 

State of Wyoming against any person (including any past or present generator, past or present 

transporter, or past or present owner or operator of a treatment, storage or disposal facility) who 

has contributed or who is contributing to such handling, storage, treatment, transportation or 

disposal to restrain such person from such handling, storage, treatment, transportation, or 

disposal, to order such person to take such other action as may be necessary, or both. A 

transporter shall not be deemed to have contributed or to be contributing to such handling, 

storage, treatment, or disposal taking place after such waste material or hazardous waste has left 

the possession or control of such transporter if the transportation of such waste was under a sole 

contractual arrangement arising from a published tariff and acceptance for carriage by common 

carrier by rail and such transporter has exercised due care in the past or present handling, 

storage, treatment, transportation and disposal of such waste. The Director may also take other 

action under Section 270(p) of this Chapter including, but not limited to, issuing such orders as 

may be necessary to protect public health and the environment.

(q) MONITORING, ANALYSIS AND TESTING.

RCRA §3013(a) (i) Authority of the Director. If the Director determines, upon receipt of any 

information, that:

which hazardous waste is, or has been, stored, treated, or disposed of, or

RCRA §3013(a)(2) (B) The release of any such waste from such facility or site may 

present a substantial hazard to human health or the environment, the Director may issue an order 

requiring the owner or operator of such facility or site to conduct such monitoring, testing, 

analysis, and reporting with respect to such facility or site, as the Director deems reasonable to 

ascertain the nature and extent of such hazard.
1-32

RCRA §3013(b) (ii) Previous Owners and Operators. In the case of any facility or site not in 

operation at the time a determination is made under Section 270(q)(i) of this Chapter with respect 

to facility or site, if the Director finds that the owner of such facilities could not reasonably be 

expected to have actual knowledge of the presence of hazardous waste at such facility or site 

and of its potential for release, the Director may issue an order requiring the most recent previous 

owner or operator of such facility or site who could reasonably be expected to have such actual 

knowledge to carry out the actions referred to in Section 270(q)(i) of this Chapter.

RCRA §3013(c) (iii) Proposal. An order under Section 270(q)(i) or Section 270(q)(ii) of this 

Chapter shall require the person to whom such order is issued to submit to the Director within 30 

days from the issuance of such order a proposal for carrying out the required monitoring, testing, 

analysis, and reporting. The Director may, after providing such person with an opportunity to 

confer with the Director respecting such proposal, require such person to carry out such 

monitoring, testing, analysis, and reporting in accordance with such proposal, and such 

modifications in such proposal as the Director deems reasonable to ascertain the nature and 

extent of the hazard.

RCRA §3013(d) (iv) Monitoring, testing, or analysis carried out by the Director.

RCRA §3013(d)(1) (A) If the Director determines that no owner or operator referred to in 

Section 270(q)(i) or Section 270(q)(ii) of this Chapter is able to conduct monitoring, testing, 

analysis, or reporting satisfactory to the Director, if the Director deems any such action carried out 

by an owner or operator to be unsatisfactory, or if the Director cannot initially determine that there 

is an owner or operator referred to in Section 270(q)(i) or Section 270(q)(ii) of this Chapter who is 

able to conduct such monitoring, testing, analysis, or reporting, the Director may:

RCRA §3013(d)(1)(A) (I) Conduct monitoring, testing, or analysis (or any 

combination thereof) which the Director deems reasonable to ascertain the nature and extent of 

the hazard associated with the site concerned, or 

RCRA §3013(d)(1)(B) (II) Authorize a local authority or other person to carry out 

any such action.

RCRA §3013(d)(3) (B) For purposes of carrying out Section 270(q)(iv) of this Chapter, 

the Director or any authority or other person authorized under Section 270(q)(i)(A) of this 

Chapter, may exercise the authorities set forth in W.S. 35-11-109(a) and W.S. 35-11-110(a).

RCRA §3013(e) (v) Enforcement. The Director may commence a civil action against any 

person who fails or refuses to comply with any order issued under Section 270(q)(iv) of this
