CPF No. 5-2007-5015 FINAL ORDER On August 28 - 31, 2006, pursuant to 49 U. S. C. ( 60117, a representative of the Pipeline and Hazardous Materials Safety Administration, Office of Pipeline Safety (OPS), conducted an on- site pipeline safety mspection of CHS Inc. 's (CHS or Respondent) Integrity Management Program (IMP) in Laurel, Montana CHS operates approximately 1, 086 miles of hazardous liquid pipelines in Montana and North Dakota, much of which runs through environmentally sensitive areas, As a result of the mspection, the Director, Western Region, OPS (Director), issued to Respondent, by letter dated April 4, 2007, a Notice of Probable Violation and Proposed Compliance Order (Notice). In accordance with 49 C. F. R, $ 190. 207, the Notice proposed finding that Respondent had violated various provisions of 49 C. F. R. $195. 452 and ordering Respondent to take certain measures to correct the alleged violations Respondent responded to the Notice by letter dated May 1, 2007 (Response). Respondent did not contest the allegations of violations and indicated that it intended to complete the work identified in the proposed Compliance Order by November 1, 2007. Respondent further requested that in the event a Final Order should be issued prior to that date, an extension be granted for Respondent to complete the work. As of the date hereof, Respondent has not provided documentation showing completion of the work identified in the Compliance Order. In its Response, CHS did not request a hearing and therefore has waived its right to one. FINDINGS OF VIOLATION In its Response, Respondent did not contest the allegations in the Notice that it violated 49 C. F. R. Part 195, as follows' Item 1: Item 1 of the Notice alleged that Respondent violated various provisions of 49 C. F. R. $ 195. 452(i), which states, in relevant part: g 195. 452 Pipeline integrity management in high consequence areas. (a) " (i) 8'hat preventive and mitigative measures must an operator take to protect the high consequence area? (1) General requirements An operator must take measures to prevent and mitigate the consequences of a pipeline failure that could affect a high consequence area. These measures include conducting a risk analysis of the pipeline segment to identify additional actions to enhance public safety or environmental protection. Such actions may include, but are not limited to, implementing damage prevention best practices, better monitoring of cathodic protection where corrosion is a concern, establishing shorter inspection intervals, installing EFRDs on the pipeline segment, modifying the systems that monitor pressure and detect leaks, providing additional traming to personnel on response procedures, conducting drills with local emergency responders and adopting other management controls. . . . (3) Leak detection An operator must have a means to detect leaks on its pipeline system. An operator must evaluate the capability of its leak detection means and modify, as necessary, to protect the high consequence area. An operator's evaluation must, at least, consider the following factors length and size of the pipeline, type of product carried, the pipeline's proximity to the high consequence area, the swiftness of leak detection, location of nearest response personnel, leak history, and risk assessment results. (4) Emergency Flow Restrtcting Devices (EFRD) If an operator determines that an EFRD is needed on a pipeline segment to protect a high consequence area in the event of a hazardous liquid pipeline release, an operator must install the EFRD. In making this determmation, an operator must, at least, consider the following factors — the swiftness of leak detection and pipeline shutdown capabilities, the type of commodity carried, the rate of potential leakage, the volume that can be released, topography or pipeline profile, the potential for ignition, proximity to power sources, location of nearest response personnel, specific terrain between the pipeline segment and the high consequence area, and benefits expected by reducing the spill size. Item 1(A): Item 1(A) of the Notice alleged that, as of the date of the inspection, Respondent had violated ) 195 452(i)(1) by failing to take measures to prevent and mitigate the consequences of a pipeline failure that could affect a high consequence area. Specifically, the Notice alleged that Respondent failed to conduct a risk analysis of its pipeline segments to identify additional actions to enhance public safety or environmental protection. CHS did not contest this allegation. Accordingly, based upon a review of the record, I find that Respondent violated 49 C. F. R. $ 194 452(i)(1)) by failing to have completed a risk analysis of its pipeline segments. Item 1(B): Item 1(B) of the Notice alleged that Respondent had violated 49 C. F.

Accordingly, based upon a review of the record, I find that Respondent violated 49 C. F R )195. 452(i)(3) by failing to have completed, as of the date of the inspection, an evaluation of the leak detection capabilities of its pipeline system. Item 1(C): Item 1(C) of the Notice alleged that Respondent had violated 49 C. F. R. ) 195. 452 (i)(4), as stated above, by failing to complete, as of the date of the inspection, an evaluation to determine if there were a need for additional EFRDs on any segment of its pipeline system in order to protect a high consequence area in the event of a release. In its Response, CHS did not contest the allegation but indicated that it intended to comply with the actions required under the proposed Compliance Order by November 1, 2007. Accordingly, based upon a review of the record, I find that Respondent violated 49 C. F. R. $195 452(i)(4) by failing to have completed, as of the date of the inspection, an evaluation to determine if there were a need for additional EFRDs on any segment of its pipeline system. Item 2(A): Item 2(A) of the Notice alleged that Respondent violated 49 C. F. R $ 195. 452(j)(2), which states: g 195. 452 Pipeline integrity management in high consequence areas. (a) " (j) What rs a continual process of evaluation and assessment to maintain a pipeline's integrity? (1) General After completing the baseline integrity assessment, an operator must continue to assess the line pipe at specified intervals and periodically evaluate the integrity of each pipeline segment that could affect a high consequence area. (2) Evaluation An operator must conduct a periodic evaluation as frequently as needed to assure pipeline integrity. An operator must base the frequency of evaluation on risk factors specific to its pipeline, including the factors specified in paragraph (e) of this section. The evaluation must consider the results of the baseline and periodic integrity assessments. . . . The Notice alleged that Respondent had violated ( 195 452(j)(2) by failing to conduct, as of the date of the inspection, an annual evaluation of its pipeline system, as required by Article 7 1 of CHS' integrity management program. In its Response, Respondent did not contest the allegation but indicated that it intended to comply with the actions required under the proposed Compliance Order by November 1, 2007. Accordingly, based upon a review of the record, I find that Respondent violated 49 C. F. R. $195. 452(j)(2) by failmg to have conducted, as of the date of the inspection, a periodic evaluation of the integrity of its pipeline system, as required by Article 7. 1 of Respondent's IMP. Item 3(A): Item 3(A) of the Notice alleged that Respondent violated 49 C. F R. ) 195. 452(k), which states: f 195. 452 Pipeline integrity management in high consequence areas. (a) "~ (f) What are the elements of an integrity management program~ An integrity management program begins with the initial framework. An operator must continually change the program to reflect operating experience, conclusions drawn from results of the integrity assessments, and other maintenance and surveillance data, and evaluation of consequences of a failure on the high consequence area An operator must include, at minimum, each of the following elements in its written integrity management program: (1) " (7) Methods to measure the program's effectiveness (see paragraph (k) of this section). . . (k) 8'hat methods to measure program effecttveness must be used~ An operator's program must include methods to measure whether the program is effective in assessing and evaluating the integrity of each pipeline segment and in protectmg the high consequence areas. See Appendix C of this part for guidance on methods that can be used to evaluate a program's effectiveness. The Notice alleged that Respondent had violated 49 C. F. R. $ 195 452(k) by failing to conduct ongoing evaluations of the effectiveness of its IMP in assessing and evaluating the integrity of each pipeline segment and in protecting high consequence areas. Specifically, it alleged that CHS had failed to conduct an annual evaluation of its IMP, as required under Article 9. 1 of such plan. In its Response, Respondent did not contest the allegation but indicated that it intended to comply with the actions required under the proposed Compliance Order by November 1, 2007. Accordingly, based upon a review of the record, I find that Respondent violated 49 C. F. R. $195. 452(k) by failing to have conducted, as of the date of the inspection, periodic evaluations of the effectiveness of its IMP in assessing and evaluating the integrity of each pipelme segment and in protecting high consequence areas. These findings of violation will be considered prior offenses in any subsequent enforcement action taken agamst Respondent.
