5 1. Opening of Meeting The meeting was called to order by Dave Snell, Chairmen at approximately 8:30 AM on April 28, Self-introductions 3. Chair s Report: Dave Snell thanked those that came to the meeting. One Item before getting started: This was one of our first NFPA sponsored meetings that there were less than the minimum number of rooms (committee member staying at the hotel) booked to obtain a meeting room discount. So that we do not have to start charging a meeting fee, we are asking that attending members stay, if possible, at the same hotel the meeting is being held. Dave Snell outlined the objective of the meeting. Since the agenda was changed about a week before the meeting, Dave reviewed the complete agenda. Dave explained that we would work though subcommittees (task groups) to cover the comments. Each chair will present their recommendations to the main committee for review and discussion. We will follow standard NFPA committee procedures in addressing each comment as Jason has outlined. During new business, we will be discussing the possibility of forming correlating committees for each document. We have had many new items added to NFPA 850. We want to make sure that we have also addressed the same items in NFPA 851 and NFPA 853. We need to reduce the likelihood of the gaps between all the documents. One way of doing this is to have correlating committees for each document. After we have completed public comments, we will open the floor to address committee comments and new business. There is a need to clarify the definition of conveyors in Chapter 7 (not new material). There was one item for NFPA 853 that was submitted late, but is not new material. It is considered additional information to help clarify the comment. One item of interest, there are still issues being discussed related to dust in plants, including what OSHA is doing. NFPA 654 has visited one of Tom O Connor s plants. The PRB group will be meeting in Chicago to discuss Best Practices. NFPA is having a presentation in Baltimore for Dust Suppression. Dave thanked everyone for continuing to work on the three documents and coming to the meeting. These documents have had and will continue to have an impact on the industry.

6 4. Minutes of last Meeting: Hugh Castles had several minor editor changes for the Minutes of the ROP Meeting from August The changes were noted and a revision will be sent to Jason. The minutes were then approved as noted. The committed voted to accept last meeting s minutes (Don Birchler voted to accepted, Scott Pruett seconded the motion.) The minutes and any comments will be posted on the NFPA s committee website. 5. Staff Liaison s Report - Jason Gamache Jason reviewed the committee procedures for handling comments. The committee may submit their comments during the meeting. However, no new material may be added. Participation is granted by chair Voting 2/3 majority, letter ballot is official Reviewed the various ways the committee can accept or reject a proposal No new material can be added to the document during the meeting. If committee has new material, it must submit a proposal for the next cycle. Ballots will be sent out in a few weeks and must be return by mail or fax. Note: all members both principal and their alternate need to respond. 6. Presentations 3 M Company Paul Rivers A presentation was made by the Paul Rivers of the 3M Company regarding NOVEC 1230 fluid as a clean extinishing agent. Mr. Rivers s presentation covered the various full-scale tests that were conducted in Spain using NOVEC 1230 for protection in a transform vaults. There were a series of three different test scenarios, a totally enclosed room, a partial vented room (20% open) and a full open (roof removed) room. Fire Trace Automatic Fire Suppression Systems (wind turbine applications) A presentation of the Fire Trace Fire Suppression System for wind turbine enclosures and associated electrical cabinets was presented to the committee. The system uses a local flooding application of NOVEC 1230 over the area being protected. They have also used FM200 in some installations. The system can be design for both direct and an indirect application. 7. ECG Meeting - ROC Discussion NFPA Review of public comments Following proper procedures, each committee chair made a proposal to the main committee as to how to handle the comment being discussed. Each comment was reviewed and issues were discussed by the full committee. A vote was made by the committee to as to the action recommended by the chair.

7 There were 15 public comments related to NFPA 850 Chapter 2 Steve Behrens, Chair one comment - Chapter 4 ( new chapter 16) - Hugh Castles, Chair one comment Chapter 7 - Scott Pruett, Chair - four comments Chapter 10 Ricky Johnson, Chair eight comments Annex D John Koester, Chair one Comment (this was a committee comment submitted as a public comment so that the information was presented a head of time. The comment consisted of updated loss information) NFPA Review of public comments Chapter 7 Amjad Mian, Chair One comment NFPA Subcommittee comments There was one committee comment that was submitted regarding thermoset insulation and the need for protection of the hydro-generator windings. The committee had a long discussion as to the information being presented and the loss history that was referenced in the comment. Clarification of the committee s intent regarding proposal (A.7.3.1) was made. Annex D - John Koester one Comment. (This was a committee comment submitted as a public comment so that the information was presented a head of time. Updated loss information was added to NFPA 851). NFPA Subcommittee comment Robert Wiechert presented editorial information to the committee that helps clarify several NFPA 853 proposals. ( No new Material) NFPA Subcommittee comment 1. It was expressed by Todd Stinchfield FM Global, that the reference the committee used to evaluate the use of Compressed Air Foam systems for the protection of transformers was incorrect. FM did not provide an approval for the use of the product to protect transformers. After further research, the sub-committee found that two different documents were attached together, one the FM approval, the other an independent Canadian test lab results. The Canadian tests were related to using the product for transformer protection, but not part of FM s approval. The committee felt it was best to remove the comment about using Compressed Air Foam for the protection of transformers at this time.

8 2. The second comment was related the committee specifying the same design density for all applications of Compress Air Foam. Currently, NFPA 11 committee has issued a TI Amendment that addresses the installation of Compressed Air Foam systems. After much discussion on the subject, the NFPA 850 committee concluded it would be best to reference the use and installation of Compressed Air Foam systems back to NFPA Doug Brandes presented a committee comment regarding the protection of critical Conveyors in the plant. After much discussion regarding how we would define a critical conveyor and the issue that the section in question is primarily for coal conveyor, Doug withdrew his proposed comment. Because the discussion was going into areas of new material, it was stated that the sub committee for chapter 7 would need to look at how we may need to define critical conveyors and if a change is needed, they will need to be made a proposal to be submitted for next cycle. 4. There was an editorial comment for proposal section that changed generators to generator/torque convector for clarification. 8. New Business Committee Structure After Dave discussed the concept of creating correlating committees for the various documents with Jason, it was expressed the process would not be easy. The Standards Council is not necessarily in favor of forming correlating committees. That said, we would continue our present structure. The assigned task groups will continue to handle the various chapters. Dave asked Rick Johnson to continue to oversee the new technology task group. As always, we will continue to bring in expertise as need into each task group. During the next cycle, we will need to look at bringing NFPA 851 into NFPA 850 to eliminate the duplication of information and to assure that the technical information is consistent. Dave will need to write a memo to the Standards Council that specifies our reasoning and justification for combining the two documents. Bernard Bischoff express the concern while the NFPA 850/851documents has been around however, once you get away from the Power Generation Industry most individual are not aware our documents exist or the importance of them. Perhaps a task group can be create that would better market the documents. Jason indicated that the NFPA puts more marketing efforts into their top selling documents. It was expressed that the committee needs to look at other means to promote our documents. It was agreed for the next meeting, a task group would work on how we will address this issue. Assigned to the task group were Robert Wiechert, Bernard Bischoff, Daryl Bessa, Don Birchler, Don Drewry, and Dave Snell. Jason reviewed the set-up of NFPA s E-committee Web page. Any task group or committee can use the web site to post information. 9. Future Meetings

9 We are finishing the Fall 2009 cycle with the issuing of the new documents. This means we would be entering a Fall 2014 cycle for the next release of the documents. NFPA only supports the ROP and the ROC meetings at this time. Any pre-rop meeting would be up to the committee to coordinate. Dave expressed that we would likely try to coordinate our meeting after one of the EEI meetings. This way most of the individuals that attend the EEI meeting can also attend our committee meeting. We will look at the possibility of following the Fall 2010 EEI meeting with a 1 ½-day NFPA 850 meeting. We would also want to make sure we stay at the same hotel as the EEI group does. 10. Losses Dave To complete 11. ROC Ballot The committee was reminded that we still would need to vote on the ballots. Our committee actions are not formal votes. To be accepted, we will need 2/3 majority. Meeting Adjournment. Respectfully Submitted, Don Drewry

The act of replacing air in a fuel gas pipeline with gas by direct replacement so rapidly that a minimum of mixing between the two gases occurs Gas Blowing. The act of cleaning a fuel gas pipeline using high pressure/velocity fuel gas. Note: This Proposal originates from Tentative Interim Amendment (TIA 1004) issued by the Standards Council on October 20, The 2010 edition of NFPA 850, Recommended Practice for Fire Protection for Electric Generating Plants and High Voltage Direct Current Converter Stations, contains a conflict with NFPA 54, National Fuel Gas Code, in that it is referenced in the Recommended Practice while NFPA 54 states that it excludes utilities. The proposed TIA intends to correct this conflict as well as offer guidance that would lessen the recognized hazards associated with the cleaning, inerting and purging of fuel gas piping systems associated with electric generating plants. The reference and applications to NFPA 54 has been clarified in the proposed TIA as it applies to low pressure fuel gas piping systems at power generating plants. New references are included for applicable documents that provide guidance for high pressure fuel gas piping systems. In addition, guidance is provided for the safe cleaning, inerting and purging of fuel gas piping systems in both new construction phase as well as repair and maintenance phase. Emergency Nature: In February 2010, there was a large natural gas explosion at the 620 MW gas and oil fired Kleen Energy Plant located in Middletown, Connecticut. The plant was 95% complete and was planned to go on line in June The explosion resulted in six fatalities. The facility was conducting a gas blow of the fuel gas piping using natural gas when the explosion occurred. The physical damage was in the millions and caused a delay in the project for two years. The proposed TIA intends to address potential hazards related to this incident. The proposed TIA meets Sections 5.3(b) and 5.3(d) of NFPA s Regulations Governing Committee Projects for justification of its emergency nature, which read as follows: 5.3(b) The document contains a conflict within the document or with another NFPA document. 5.3(d) The proposed TIA intends to offer to the public a benefit that would lessen a recognized (known) hazard or ameliorate a continuing dangerous condition or situation.

Gas purging, whether indoor or outdoor, should be attended, monitored with a combustible gas indicator, and stopped when fuel gas purity indicates completion (e.g. 95% fuel gas) Gas purging at pressures below 125 psig (861.8 kpa) should be performed in accordance with the applicable sections of NFPA Gas purging at pressures exceeding 125 psig (861.8 kpa) should be performed in accordance with or * Maintenance and Repair. The hazards associated with flammable gases and asphyxiants should be considered when performing maintenance and repairs Fuel gas piping should be inerted in accordance with prior to maintenance and repair When fuel gas piping is being inerted with asphyxiants, the area should be ventilated or considered a confined space as regulated by US Department of Labor OSHA 29 CFR , Permit Required Confined Space Standard. Note: This Proposal originates from Tentative Interim Amendment (TIA 1004) issued by the Standards Council on October 20, The 2010 edition of NFPA 850, Recommended Practice for Fire Protection for Electric Generating Plants and High Voltage Direct Current Converter Stations, contains a conflict with NFPA 54, National Fuel Gas Code, in that it is referenced in the Recommended Practice while NFPA 54 states that it excludes utilities. The proposed TIA intends to correct this conflict as well as offer guidance that would lessen the recognized hazards associated with the cleaning, inerting and purging of fuel gas piping systems associated with electric generating plants. The reference and applications to NFPA 54 has been clarified in the proposed TIA as it applies to low pressure fuel gas piping systems at power generating plants. New references are included for applicable documents that provide guidance for high pressure fuel gas piping systems. In addition, guidance is provided for the safe cleaning, inerting and purging of fuel gas piping systems in both new construction phase as well as repair and maintenance phase. Emergency Nature: In February 2010, there was a large natural gas explosion at the 620 MW gas and oil fired Kleen Energy Plant located in Middletown, Connecticut. The plant was 95% complete and was planned to go on line in June The explosion resulted in six fatalities. The facility was conducting a gas blow of the fuel gas piping using natural gas when the explosion occurred. The physical damage was in the millions and caused a delay in the project for two years. The proposed TIA intends to address potential hazards related to this incident. The proposed TIA meets Sections 5.3(b) and 5.3(d) of NFPA s Regulations Governing Committee Projects for justification of its emergency nature, which read as follows: 5.3(b) The document contains a conflict within the document or with another NFPA document. 5.3(d) The proposed TIA intends to offer to the public a benefit that would lessen a recognized (known) hazard or ameliorate a continuing dangerous condition or situation.

26 Page 16 of 23 Public Input No. 13-NFPA [ Section No ] * ANSI/ASME B31.1, Power Piping, should be followed in the design of HTF piping systems. Piping and fittings should be properly designed to resist an exposure fire until protection can be achieved by water spray. To reduce possible sources of leaks, use of rotating-ball-joint-type connections instead of flexible hose connections Careful consideration should be given to the design, application, construction, and installation of connections (e.g., rotating ball joint, flexible hose, etc.) employed in areas such as the HTF loop connection connections of adjacent solar collector assemblies should be considered so as to prevent possible sources of HTF leaks. Gaskets and seals should be compatible with HTF. Flanges and piping connections on HTF systems should have guards. Note: This Proposal originates from Tentative Interim Amendment (TIA 982) issued by the Standards Council on August 5, The statement in the NFPA 850 documentation, To reduce possible sources of leaks, consider use of rotating-balljoint-type connections instead of flexible hose connections in areas such as the HTF loop connection of adjacent solar collector assemblies, limits the utilization of new technologies. Emergency Nature: The proposed TIA intends to correct a circumstance in which the revised document has resulted in an adverse impact on a product or method that was inadvertently overlooked in the total revision process, or was without adequate technical (safety) justification for the action. Restricting usage of new technologies in parabolic trough is an emergency issue as the current version limits and discourages the utilization of new proven technologies. NTF connections are highly engineered devises. Fire accidents have occurred when careful consideration was not given to the design, application, construction and installation of the connections regardless of the connection type used.

27 Page 17 of 23 Public Input No. 16-NFPA [ New Section after A ] A NFPA 54, National Fuel Gas Code, provides guidance for the design, installation, and testing of applications operating at pressures less than 125 psig (861.8 kpa), such as hot water heaters, space heaters, cooking applications, auxiliary boilers and emergency generators, and should be considered a good reference for these type applications in power generating facilities. NFPA 54 specifically excludes piping in electric utility power plants that supplies gas utilized directly as the fuel in the generation of electricity. These systems typically operate at pressures greater than 125 psig (861.8 kpa) which is beyond the scope of NFPA 54. A.7.2.4(1) Pigging is discussed at length in CGA G-5.6 Section 6, which describes mechanical scraping or pigging. A.7.2.4(2) Aerated water jet flushing is a process where highly aerated water is forced as a slug down a pipe at speeds of 40 to 80 feet per second (12.2 to 24.4 meters per second) to dislodge debris, weld slag, corrosion deposits, and other foreign objects from the pipe. A.7.2.4(3) High-pressure water jet flushing is a process where high-pressure jets are used to scour debris, weld slag, corrosion deposits, and other foreign objects from the pipe. A.7.2.4(4) Nonflammable gaseous media methods for clearing debris from the fuel gas piping include the use of air, an inert gas (such as nitrogen), or steam. These methods employ the same principle as a gas blow, with the nonflammable medium substituted for the natural gas. The key to making any of these methods work is to achieve sufficient flow velocity within the piping system to blow any debris that can damage the equipment in operation out of the piping. Guidance regarding recommended flow rates should be provided by the equipment manufacturer. A It is often recommended that oxidants like air be diluted by a nonreactive ( inert ) gas, such as nitrogen, carbon dioxide, or argon, to levels such that when a flammable gas is introduced a flammable mixture is not generated. The reverse is also true; dilute the fuel before adding air. Flammability ranges for various fuels are noted as part of Table of NFPA 497. While this addresses fire hazards, the nonreactive gas is an asphyxiant and proper cautions are to be followed. This best practice is discussed in CGA G-5.6 Section A Maintenance and repair of fuel gas piping should be performed in accordance with Subsection of CGA G-5.6.

30 Page 20 of 23 Public Input No. 19-NFPA [ Section No. C ] C Tests were conducted by FM Global in [7] The test configuration included a turbine pedestal measuring 15 ft wide 20 ft long 18 ft high (4.6 m 6 m 5.5 m), with a 7.5 ft (2.3 m) grated walkway extending along one edge and an adjacent lube oil tank with a dike surrounding the tank. Twentythree full-scale tests were conducted in the FM Global large burn laboratory. Initially, they were intended as demonstration tests to show clients potential fire risks. However, early in the planning process, the scope of the effort was expanded to include a research component. Spray fire, three-dimensional fire, and pool fire testing was conducted using various fire protection systems. Mineral oil was used with a flash point of 261 F (127 C) and a 19,080 Btu/lb (44,345 kj/kg) heat of combustion. Ten spray fire tests were conducted. Lube oil was pumped through a nozzle under pressure at a rate of 20 gpm (75.7 L/min). The spray fire under free burn conditions generated a heat-release rate of 40 MW. The nozzle was located above the lube oil tank and directed toward the ceiling. Protection used included ceiling sprinkler protection only and local protection near the spray: 8 10 ( m) spacing with fusible link heads and 5 5 ft ( m) spacing with open head sprinklers. The open head sprinkler arrangement used sprinklers with four different K factors (2.6, 5.6, 8.0, 11.2 gpm/psi 1 2 ) located 6 ft (1.8 m) above the spray. Ceiling temperatures during spray fires reached 1500 F (816 C) without sprinkler protection and slightly less with ceiling sprinklers. Closed head sprinklers on 8 8 ft ( m) spacing did not operate during the spray fire portion of the test. Open head sprinklers on 5 5 ft ( m) spacing with a K factor of 8.0 and a discharge pressure of 50 psi (3.5 bar) or greater did not extinguish but seemed to be most effective in controlling temperatures from the spray fires. This protection arrangement reduced gas temperatures at the ceiling from a maximum of 1500 F (816 C) to below 400 F (204 C). Two three-dimensional fires were conducted. A flowing fire simulating a leak at a fitting on the turbine operating floor was ignited and allowed to flow off the platform into a pan on the ground floor. The flow rates varied from 6.0 to 10.5 gpm (22.7 to 39.7 L/min). Automatic sprinkler protection was provided below the operating floor and below the grated walkway around the turbine. Automatic sprinkler protection did not control the three-dimensional component but appeared to limit the size of the pool fire on the ground floor. Eleven pool fire tests were conducted and compared with the results of another pool fire test with sprinklers at a higher elevation. Tests were conducted with below the turbine pedestal with lube oil contained in a 81 ft 2 (7.5 m 2 ) pan. Sprinkler protection was about 15 ft (4.6 m) above the oil surface. Densities of 0.20 and 0.30 gpm/ft 2 (12 and 18 mm/min) were used. Closed head and open head sprinkler protection was used. Pool fires were most reliably extinguished by sprinklers with a density of 0.30 gpm/ft 2 (12 L/min m 2 ). Another pool fire test series was conducted at 30 ft (9.1 m). [8] It was found at an elevation of 30 ft (9.1 m) above the oil surface that a density of 0.40 gpm/ft 2 (16 mm/min) was needed to extinguish a pool fire. It was concluded that sprinkler density needed depends on height above the pool fire.
