11010. Interpretation.
(a) Consistent with rule 1304 of the Commission Rules of Practice and Procedure, 4 CCR 723-1, an operator may file a petition seeking a declaratory order that resolves a controversy or uncertainty regarding any statute, Commission rule, regulation, and/or Commission decision. The requestor shall include with each request, at least the following:
(I) the statutory provision(s), Commission rule(s), regulation(s). and/or decision(s) at issue;
(II) the specific instance or illustration of the application of the statutory provision(s), Commission rule(s), regulation(s), and/or decision(s) that causes the controversy or uncertainty; and (III) the complete petitioner’s contact information.
(IV) The petition may also include a request for expedited treatment if an interpretation is needed quickly and good cause exists.
(b) Upon receipt of the petition for a declaratory order, the Commission will consider whether to accept the filing consistent with rule 1304 of the Commission’s Rules of Practice and Procedure, 4 CCR 723-1.
(c) If the petition requires interpretation of a federal regulation incorporated by reference into these rules and the Commission accepts the petition, PHMSA must review the Commission’s interpretation of the federal regulation. The Commission’s decision interpreting the federal regulation, and the reasons therefore, shall issue as an interim decision that shall be provided to the Office of Pipeline Safety for final review. Any response by the Office of Pipeline Safety shall be incorporated into the Commission’s final decision.
(d) Nothing in these rules prohibits an operator from contacting the PSP Chief or PSP Lead Engineer for informal assistance. Consistent with paragraph 1007(d) of the Commission’s Rules of Practice and Procedure, 4 CCR 723-1, opinions expressed by the PSP Chief or PSP Lead Engineer do not represent the official views of the Commission, but are designed to aid the public and to facilitate the accomplishment of the Commission’s functions. Nothing communicated by the PSP Chief or PSP Lead Engineer constitutes legal advice. 11011. Waiver – Non-emergency.
(a) An owner or operator may request a waiver or a variance from any of these rules in accordance with § 40-2-115, C.R.S., 49 U.S.C. § 60118(d), and paragraph 1003(b) of the Commission’s Rules of Practice and Procedure 4 CCR 723-1. Requests for waiver from the standards in 49 C.F.R. Part 192 that are incorporated by reference into these rules that are made pursuant to 49 C.F.R. Part 192.1013 are subject to the requirements of both paragraphs (b) and (c) below.
(b) The petition shall include:
(I) information required by rule 1003 paragraph (c);
(II) the specific instance or illustration of the rule’s application requiring modification/waiver;
(III) proposed alternatives to compliance with the regulation (e.g., additional inspections and tests, shortened reassessment intervals, etc.);
(IV) an explanation of the necessity with supporting evidence and documentation, including:
(V) a certification that the modification/waiver is consistent with pipeline safety; and (VI) the complete operator contact information.
(c) An owner or operator may file a petition for waiver under 49 C.F.R. Part
192.1013 to deviate from the standards in 49 C.F.R. Part 192 that are
incorporated into these rules to alter the frequency of periodic inspections and tests on the basis of an engineering analysis and risk assessment.
(I) A request for waiver for an alternative frequency of inspections and tests required under Part 192 will be granted if the request is found to be not inconsistent with pipeline safety. For intrastate facilities, an operator must file its proposal as a petition for waiver through the Commission’s E-Filings System at least 120 days before the requested effective date.
(II) An owner or operator may implement an approved reduction in the frequency of a periodic inspection or test only where the operator has developed and implemented an integrity management program that provides an equal or improved overall level of safety despite the request for reduced frequency of periodic inspections.
(III) In addition to the information in subparagraph (b) above, each petition filed under this subsection must include the following information:
(IV) After receiving notice of the petition, the PSP Chief will confer with the Office of Pipeline Safety on the waiver requested by the owner or operator. The PSP Chief will file a notice in the petition proceeding indicating whether the request should be accepted by the Commission and if so, whether additional conditions or limitations that are relevant and in the public interest should be adopted. The Commission shall consider the petition for waiver and the notice filing of the PSP Chief in rendering a decision.
(d) PHMSA Review: If the Commission grants a petition filed by an owner/operator for a waiver of a federal rule that is incorporated into the Commission rules, PHMSA must review the Commission’s decision, except for petitions for waiver covered by paragraph (c) above. The Commission’s decision granting a waiver request that requires PHMSA review, and the reasons therefore, shall issue as an interim decision that shall be provided to the Office of Pipeline Safety for final review pursuant to 49 U.S.C. § 60118(d). Any response by the Office of Pipeline Safety shall be incorporated into the Commission’s final decision. 11012. Waiver – Emergency.
(a) An operator may file a petition to request an emergency waiver or variance in situations that require expedited review that is otherwise inconsistent with § 40-2- 115, C.R.S., 49 U.S.C. § 60118(d), and the Commission’s Rules of Practice and Procedure.
(b) An emergency waiver request will be granted if it is in the public interest, is consistent with pipeline safety, and is necessary to address an actual or impending emergency involving pipeline transportation, including emergencies caused by natural or manmade disasters.
(c) An emergency waiver is an order by which the Commission may temporarily modify compliance with state pipeline regulations for affected pipeline owners or operators and the Commission may waive compliance with a safety regulation if, after receiving notice on an incorporated federal rule, PHMSA concurs in the action.
(d) The Commission will determine on a case-by-case basis what duration of waiver or variance is necessary to address the emergency. However, as required by statute, no emergency waiver may be issued for a period exceeding 60 days. Each emergency waiver will automatically expire on the date stated in the Commission’s decision.
(e) An operator may request an emergency Special Permit modifying or waiving of any of these rules by submitting a written request as follows.
(I) If the request concerns a Colorado-specific rule then no subsequent review by PHMSA is required. The requestor shall file a petition for the emergency waiver with the Commission using one of the following methods:
(II) If the request concerns a federal rule incorporated by reference into these rules, a review by PHMSA is required. The requestor shall submit a petition for the emergency waiver directly to the Commission using one of the methods described above and to PHMSA using any of the following methods:
(f) The requestor shall include with each emergency waiver petition:
(I) the information required by rule 1003 paragraph (c);
(II) an explanation of the actual or impending emergency;
(III) the specific instance or illustration of the rule’s application requiring modification/waiver;
(IV) proposed alternatives to compliance with the regulation (e.g., additional inspections and tests, shortened reassessment intervals, etc.);
(V) to the extent possible, as much of the information as is required in paragraph 11011(c); and (VI) measures to be taken after the emergency situation or permit expires, whichever comes first, that will confirm/assure long-term operational reliability of the facility impacted by the Special Permit.

(e) After an inspection, the PSP Chief will pursue one of the following:
(I) an inspection close-out indicating that no further action will be taken on final inspection findings;
(II) a RFI indicating that the inspection is ongoing without final inspection findings, to be answered within the timeframe requested in the RFI, typically 30 calendar days from the operator’s receipt of the RFI unless otherwise indicated and agreed to by the PSP Chief and the operator; or (III) a compliance action taken on final inspection findings as described in rules 11502 and 11503.
(f) If a representative of the PSP investigates an incident involving a pipeline facility, the PSP Chief of the Commission may request that the operator make available to the representative all records and information that directly or indirectly pertain to the incident, including integrity management plans and test results, and that the operator afford all reasonable assistance in the investigation.
(g) To the extent necessary to carry out the responsibilities of the Program Certification Obligations, the PSP may require testing of portions of pipeline facilities that have been involved in, or affected by, an incident. However, before exercising this authority and accepting responsibility, the PSP shall make every effort to negotiate a mutually acceptable plan with the owner of those facilities and, where appropriate, other local and state fire and safety authorities, PHMSA, the NTSB, and any known third parties for performing the testing. 11014. Advisory Bulletins.
PSP advisories or PHMSA advisory bulletins are periodically drafted and communicated to affected operators as a result of circumstances identified by the PSP, PHMSA, NTSB, or industry with the potential to become pipeline system safety risks. Operators should review these bulletins for relevancy to their individual pipeline system operations. 11015. – 11099. [Reserved].

The operator shall file its response opposing the allegations in the NOA in the proceeding and provide all relevant information it finds addresses the issues raised. If an operator opposes any alleged violation in the NOA, the matter shall be set for hearing.
(d) If the operator fails to respond as provided in this rule within 30 days of the NOA, the NOA shall be deemed opposed by the operator and shall be set for hearing as prescribed by subparagraph (c)(III) above.
11507. Compliance Action – Hazardous Facilities Order (HFO).
(a) If an inspection, audit, investigation, or test reveals that the continued operation of a pipeline or LNG facility may pose a severe and imminent risk to public safety, as determined by current regulation, industry standard, or other relevant objective technical standard, the PSP Chief may consider the pipeline or LNG facility to be a hazardous facility and file a formal complaint with the Commission against the operator of the facility. The complaint shall allege facts sufficient to establish the existence of a hazardous facility and to support an HFO issued upon conclusion of a Commission proceeding, or, if justified, a summary HFO pursuant to paragraph (i) of this rule.
(b) A formal complaint by PSP staff shall be issued, and a hearing shall be conducted in accordance with the Commission’s Rules of Practice and Procedure and Article 6 of Title 40, C.R.S.
(c) Except as provided in paragraph (i) of this rule, if the Commission finds, after hearing, that a pipeline facility or a LNG facility is hazardous to life or property, the Commission shall issue an order directing the operator to take corrective action. Corrective action may include, without limitation, suspension or restriction of the use of the pipeline facility or LNG facility, physical inspection, testing, repair, or replacement.
(d) In making a determination that a pipeline facility or a LNG facility is hazardous to life or property, the following shall be considered, as appropriate:
(I) the characteristics of the pipe used in the pipeline facility or the LNG facility involved, including (without limitation) its age; manufacturer; physical properties, including its resistance to corrosion and deterioration; and the method of its manufacture, construction or assembly;
(II) the nature of the gas transported by the pipeline facility or the LNG facility, including its corrosive and deteriorative qualities; the sequence in which the gas is transported; and the pressure required for transportation of the gas;
(III) the characteristics of the areas in which the pipeline facility or the LNG facility is located, in particular the climatic and geotechnical or geologic conditions associated with the areas, the population, the population density, and the community growth patterns of the areas;
(IV) any recommendation of the NTSB issued in connection with any investigation conducted by that Board; and (V) such other factors as may be relevant.
(e) A Commission decision finding that a pipeline facility or a LNG facility is a hazardous facility shall contain a description of the corrective action required of the operator and the date by which the operator shall complete the ordered corrective action.
(f) The Commission shall dismiss the complaint if it determines that the pipeline facility or the LNG facility is not hazardous to life or property.
(g) Upon a showing that the ordered corrective action has been completed and has eliminated the condition(s) that made a pipeline facility or a LNG facility a severe and imminent risk to public safety, the Commission shall issue an order of satisfaction. Prior to issuing an order of satisfaction, the Commission may hold a hearing to determine whether the operator has completed the corrective action and whether the corrective action has eliminated the conditions(s) that made the pipeline facility or the LNG facility hazardous to life or property. The order of satisfaction shall be issued in the complaint docket in which the hazardous facilities order was entered.
(h) The Commission may bring a formal complaint alleging the existence of a hazardous facility supporting the issuance of an HFO and an NPV in the same proceeding, but is not required to do so.
(i) If the Commission determines that the delay inherent in holding a hearing may result in, and significantly increases the likelihood of, serious harm to life or property, the Commission may issue an expedited or summary HFO before holding a hearing. The provisions of paragraph (b) of this rule shall apply to a hearing held pursuant to this paragraph. The purpose of a hearing held pursuant to this paragraph is to determine whether the summary HFO should remain in effect, should be amended, or should be rescinded. The summary HFO shall include the following:
(I) the findings that support the determination that a summary HFO is appropriate;
(II) the corrective or remedial actions required of the operator; and (III) a statement informing the operator of its right to a hearing, upon request, as soon as practicable after issuance of the order.
11508. Consent Stipulations.
(a) If a matter has been set for hearing at any time before the issuance of a decision by the Commission, the PSP Chief and the operator may agree to dispose of the matter by a consent stipulation. The consent stipulation shall be submitted to the Commission for approval or rejection.
(b) A consent stipulation executed under this rule shall include the following:
(I) an admission by the operator of facts;
(II) an express waiver by the operator of further procedural steps, including (without limitation) its right to a hearing; its right to seek judicial review, or otherwise to challenge or to contest the validity of the consent stipulation; and its right to seek judicial review of the Commission order accepting the consent stipulation;
(III) an acknowledgment by the operator that the NPV may be used to construe the terms of the consent stipulation; and (IV) a statement of the actions that the operator will take and the date by which such actions shall be completed.
(c) As appropriate, a consent stipulation executed under this rule may include a civil penalty.
11509. Subpoenas.
The Commission and Administrative Law Judge, or the Director may issue a subpoena in accordance with rule 1406 of the Commission’s Rules of Practice and Procedure. 11510. Injunctive Relief.
The Commission may request that the Attorney General bring an action in an appropriate district court for injunctive or other relief as provided in Article 7 of Title 40, C.R.S. whenever the Commission is of the opinion that an operator has engaged in, is engaging in, is about to engage in, or willfully permits any act or practice that constitutes, a violation of 49 U.S.C. §§ 60101 et seq., these rules, or an order of the Commission.
