14 Attachment E: Public Comments 15

15 of 10 1/6/ :46 AM Public Comment No. 13-NFPA [ Section No ] Nonapplication of Standard. This standard shall not apply to the following items: (1) * Piping systems covered by NFPA 2 (2) * Piping systems covered by NFPA 51 (3) * Piping systems covered by NFPA 51A (4) Fuel-dispensing facilities covered by NFPA 52 (5) * Piping systems covered by NFPA 54 (6) * Piping systems covered by NFPA 55 (7) * Piping systems covered by NFPA 58 (8) * LP-Gas (including refrigerated storage) at utility gas plants (see NFPA 59) (9) * LNG facilities covered by NFPA 59A (10)* Vehicle fuel dispensers (11) Commissioning and maintenance of equipment (12) Vent lines from pressure relief valves or devices unless such vent lines are also used for purging of flammable gas piping systems (13)* Systems regulated by U.S. Department of Transportation (DOT) 49 CFR Statement of Problem and Substantiation for Public Comment Justification: Gas gathering line systems are best addressed by DOT, (Department of Transportation) 40 cfr 191/192 regulations, AGA Purging Principles and Practices and the proprietary processes that many companies/contractors have in place. The NFPA 56 processes including leak checking, and purging with an inert gas may not be practical with buried pipe that can be many miles long without purge points and frequent isolation valves, plus condensed hydrocarbons that cannot be removed to a point of meeting the level of hydrocarbons NFPA requires in the vent effluent. Following either DOT, or AGA gives the end users appropriate Hot Work procedures to safely work under those conditions. The DOT standards contain comprehensive planning provisions somewhat similar to those required in NFPA 56. The problem is that the DOT standard only includes gas transportation piping systems once the well head gas has been processed such as would be the case leaving a mid-stream gas processing plant. This makes no sense to exclude these pipelines while including gas gathering pipelines, since both pipelines systems can be technically equivalent in terms of flow, design pressure, and installation whether the lines are entering or leaving such a plant. It is recommended that all lines technically equivalent to those under the jurisdiction of DOT 40 cfr 191/192 be treated the same way and thus remain outside the scope of NFPA 56. In these cases PHMSA 40 cfr 191 & 192 techniques have proven to be technically and safely adequate over many years. It is proposed however that addendum materials be added to address safe work practices within NFPA 56 that can be applied to these systems as non-mandatory information that may assist those performing this work. AGA Purging Principles and Practices have a specific process to calculate rates of flow to safely remove hydrocarbons and then remove the air while minimizing mixing, keeping pressures below auto-ignition point and have been used successfully for many years. And it is recommended NFPA recognize the AGA method of purging as equally safe for servicing pipelines. Neither DOT nor AGA recommends the use of natural gas to clean the pipelines of construction debris. This 16

16 of 10 1/6/ :46 AM provision of NFPA 56 is still applicable and should be followed.

18 of 10 1/6/ :46 AM Public Comment No. 15-NFPA [ Section No. 5.1 [Excluding any Sub-Sections] ] 5.1 Persons whose primary du. es fall within the scope of this standard shall be provided with training that is consistent with the scope of their job activities and assigned tasks for the cleaning or purging work to be performed. Evidence of knowledge transfer shall be included as part of the training program. complete training that includes the following components: (1) Safe work pracāces (2) The health and safety hazards associated with the Āammable gases uālized (3) Emergency response procedures (4) Supervised, on? the? job training (5) An assessment of the person s ability to perform the job duāes assigned Statement of Problem and Substantiation for Public Comment The wording that was approved in FR 12 seemed confusing to me and is made vague by the statement "evidence of knowledge transfer." This suggested substitute language is taken from NFPA 58 and was reviewed and found acceptable to the US. Chemical Safety Board prior to being published in the 2014 edition of that code.

19 of 10 1/6/ :46 AM Public Comment No. 16-NFPA [ Section No ] Training records, including dates of training, name of instructor(s), content or curriculum covered, and evidence of knowledge transfer documentaāon of the person s ability to perform the job duāes assigned, shall be maintained for a period not less than 5 years from the date of compleāon of the acāvity. Statement of Problem and Substantiation for Public Comment The problem is that "evidence of knowledge transfer" is very vague. How much knowledge must be transferred? What is considered acceptable "evidence"? The proposed change is more clearly worded and is based on the provisions of NFPA 58, which have been found to be acceptable by the U.S. Chemical Safety Board prior to the publishing of the 2014 edition of NFPA 58.

20 of 10 1/6/ :46 AM Public Comment No. 14-NFPA [ Section No. A.1.1.2(1) ] A.1.1.2(1) The application of NFPA 2 is included here for the convenience of the user: Proposed Addendum language: Section exemption (10): US DOT 40 cfr 191/192 contains guidance on carefully planning flammable gas piping activities including purging gathering line systems into and out of service. Much of this guidance addresses techniques for relatively long underground runs where there may not be isolation valves or purge points close by. AGA Purging Principles and Practices incorporates the same flammability indexes as NFPA 56 but allows the purging (not cleaning) with air in a controlled, Engineering designed procedure that still requires proper venting and monitoring. When purging gas piping into or out of service procedures are to include positive isolation of piping systems, training for employees, and careful planning for any releases including consideration of ignition sources. For guidance regarding purging procedures and planning for purging piping systems where flammable gas may exist, see NFPA 56: Standard for Fire and Explosion Protection During Cleaning and Purging of Flammable Gas Piping Systems. Pipelines should not be cleaned of construction debris by introducing natural gas at high rates and discharging in an unsafe location without control or monitoring. This part of NFPA 56 is still applicable Application. [2:1.3] This code shall apply to the production, storage, transfer, and use of hydrogen in all occupancies and on all premises. [2:1.3.1] The use of hydrogen shall include stationary, portable, and vehicular infrastructure applications. [2:1.3.2] The fundamental requirements of Chapters 1 through 8 [of NFPA 2] shall apply in addition to the use-specific requirements provided in Chapters 9 through 20, as applicable. [2:1.3.3] Exemptions. [2:1.3.4 ]This code shall not apply to the following: (1) Onboard vehicle or mobile equipment components or systems, including the onboard GH2 or LH2 fuel supply (2) Mixtures of GH2 and other gases with a hydrogen concentration of less than 95 percent by volume when in accordance with NFPA 55 (3) The storage, handling, use, or processing of metal hydride materials outside of metal hydride storage systems defined in Chapter 3 [of NFPA 2] [2:1.3.4] Statement of Problem and Substantiation for Public Comment Clarifies the use of AGA and DOT procedures for purging pipelines into and out of service.

25 Attachment F: De Minimus Quantities 26

26 Shapiro, Janna From: Sent: To: Cc: Subject: Bethany, Mike Tuesday, January 5, :21 AM Chris Buehler; Franklin R. Switzer Jr.; Denise Beach; John Puskar Shapiro, Janna RE: NFPA 56 Trask Group assignments Franklin, Sorry for the delayed response. The De Minimis task group has not done anything on this topic. Regarding the goal of this task group I have a few comments/questions that I would welcome feedback on from this group and overall committee. 1) The idea of De Minimis quantities for NFPA 56 (as I understand it) was inspired by Table from NFPA 54 that provides pipe size and length criteria below which the piping does not need be purged before work can be performed. During discussions on this topic at the last committee meeting, I got the impression that Table did not have much scientific explanation behind it. So using 54 as a basis for anything related to NFPA 56 would be speculative. 2) NFPA 54 has a defined scope regarding the gases it applies to so the flammability range, specific gravity and other parameters are known. NFPA 56, per the scope, applies to flammable gas piping. To be honest, I m not sure I completely grasp all of the possible gases this standard could cover. Obviously it covers natural gas inside electric plants and facilities that operate over 125 psig, and Hydrogen would be excluded, but what about flammable gases such as benzene that have a toxicity component as well as flammability. I know we have discussed flammable liquids and their vapors, but that would also have to be considered. I could be wrong, but if we go this route we would have to A) list all of the flammable gases that NFPA 56 covers and B) provide some de minimis criteria (size and length) for each of these gases based on their properties. 3) We could go a different route, where we provide the end user of the code with some kind of calculation that allows them to solve for the de minimis quantity based on the gas chemical makeup. I have tried to think up various scenarios regarding the volume of gas necessary to engulf an average sized worker, and other things like that, that would allow the user to back solve the de minimis quantity, but I m not sure that is the right idea. So those are my thoughts on the de minimis quantities rules for NFPA 56. I am not trying to get out of putting in the work, I just want to make sure we are heading down a path that the rest of the committee agrees with. Thank you. Sincerely, Mike Bethany, P.E.

27 Shapiro, Janna From: Sent: To: Cc: Subject: Tuesday, January 5, :30 AM Shapiro, Janna Re: NFPA 56 Trask Group assignments Mike I appreciate your always fantastic erudite analyses. I am of the opinion that one of the most important things the task force could do is to focus on just natural gas for now. I believe that would cover the vast majority of users of the document for now. 28

Cirone, Therese Convery, Pat Donsbach, Jr., Louis A. Kovach, Dennis M. Levengood, Kreg J. Naper, Robert C. Negative with Comment Danner, Lawrence M. Having now had the opportunity to review the Task Force report referenced by John Puskar, I concur there is a gap in the published guidance for gathering line piping systems between oil field well heads and the first downstream processing plant. While such piping may be considered as technically equivalent to those piping systems downstream of the processing plant and that 49 CFR 191 and 192 CAN be applied, that application is not obligatory. NFPA 56 is an appropriate forum for filling this gap and I agree with the modification proposed in Public Inputs 12 and 14 to clearly specify when NFPA 56 can be applied to such gathering lines so as to fill the gap in the published guidance. Puskar, John R. I strongly disagree with this item. It is contrary to what the appointed task force on this subject recommended. It is not clear that many of the committee members read the task force report. This change is also contrary to the stated purpose of this standard. There is no document in the oil and gas industry that today protects workers from well head related gas piping issues. This change prohibits the application of this standard to something that the oil and gas industry and the world desperately needs given that nearly almost 2 people die from fires and explosions in this industry every month. Rice, Alan I vote affirmative to addition of #14 but negative to the deletion of NFPA Titles which were struck and not included. Swiecicki, Bruce J. I do not agree with deleting the titles of the standards. It's OK that the specific editions are referenced in Section 2.2, but the reader should not have to search for the titles of each of those standards. 37
