Background

In a November 24, 2009 letter (Serial No.09-466), Dominion requested authorization to use Mine Safety Appliance Company (MSA) Firehawk Air Mask (FireHawk) Self Contained Breathing Apparatus (SCBA) charged with 35% oxygen / 65% nitrogen (35 /

65) when making sub-atmospheric containment entries at North Anna and Surry Power Stations. Additionally, Dominion requested exemptions per 10 CFR Part 20.2301 associated with 10 CFR Part 20.1703(a), 20.1703(g) and Appendix A, Footnote "a" to 10 CFR Part 20. These exemptions are necessary to support the above authorization request in that the use of supplemental oxygen in the selected SCBA has not been tested / certified by National Institute of Occupational Safety and Health (NIOSH). In a January E-mail the NRC requested additional information to complete the review of the exemption requests. The following information is provided to address the NRC request for additional information.

Request for Additional Information NRC Question 1 , page 6 of 11, the first paragraph of item "Intertek Heat and Flame Assessment" states that:

Dominion obtained a new Fire Hawk Self-Contained Breathing Apparatus (SCBA) from Mine Safety Appliance Company (MSA) and charged it with 35/65 at SPS. This SCBA was then sent to Intertek to have a Heat and Flame Resistance test performed per NFPA 1981. The tested SCBA used a fully pressurized 4500 psig cylinder so as to bound all Dominion applications (i.e.,

low and high pressure) and was equipped with a HYCAR rubber Ultra Elite facepiece. (Note: Silicone facepieces fail Chemical, Biological, Radiological, Nuclear (CBRN) testing and were therefore not considered by Dominion for use due to site fire and security commonality considerations.)

Please provide a commitment to ensure that only the HYCAR rubber facepieces with Fire Hawk SCBAs charged with 35/65 air will be used at Surry and North Anna power stations.

Dominion Response Dominion commits to use only MSA HYCAR rubber Ultra Elite facepieces in conjunction with 35/65 oxygen enriched applications of the MSA FireHawk M7 Air Mask SCBA.

Serial Number 10-062 Docket Nos. 50-280/281/338/339 Page 2 of 3 NRC Question 2 , page 5, section 5.0 "Recommendations" states that "if the following recommendations are implemented, there are no fire hazards associated with the use of this equipment." Specifically:

a. The presence of hydrocarbon contaminants in components such as the flex hoses could lead to burn out due to rapid pressurization ignition. Therefore, it is recommended to ensure that the SCBAs are not contaminated with hydrocarbons.

b. It is recommended that if any of the Cylinder Valves become difficult to seal, the valves are removed and replaced. These valves must not be used to throttle the system as this can lead to seat damage and increase the risk of ignition.

c. It is recommended to ensure that this component is not contaminated with hydrocarbon contaminants to reduce the risk of ignition by rapid pressurization.

d. It is recommended that if this regulator becomes difficult to fully close, it is removed and replaced. (Is"Stage Regulator)

Please submit a copy of MSA Firehawk Vendor manual or guidance document and Dominion's commitment to ensure compliance with use, maintenance, care, cleanliness, and repair protocols as per the document, and all applicable NIOSH requirements (i.e.,

fittings, materials, use, etc.) excluding the requirement for using Grade D quality breathing air.

Dominion Response With the exception of oxygen enrichment level (i.e., 35% oxygen,! 65% nitrogen instead of Grade D or better compressed air), Dominion currently maintains its containment use only (CUO) MSA 401/Ultralite/Custom 4500 SCBA according to all applicable regulatory and manufacturer's guidance. Dominion commits to maintaining MSA Firehawk M7 Air Mask SCBA in accordance with these same high standards. With the exception of charging CUO SCBA at NAPS and SPS with 35/65, the other MSA operations and maintenance directives as specified by MSA in their C.A.R.E. technical maintenance manual and FireHawk M7 Air Mask product literature (see Attachments 2 and 3) will be followed. Dominion seeks no other exceptions from the current NIOSH certification held by the FireHawk M7 SCBA and therefore commits to operation and maintenance of this equipment in accordance with the other aspects of its certification. As for the specific recommendations listed above, Dominion commits to the recommendations made by NASA in their Oxygen Compatibility Assessment Report submitted to the NRC on November 24, 2009 (Serial No.09-466).

Serial Number 10-062 Docket Nos. 50-280/281/338/339 Page 3 of 3 NRC Question 3 As per Intertek Tests, please provide the heating and flame resistance test performed temperature, in degrees Fahrenheit.

Dominion Response Dominion contracted Intertek, Inc. to conduct a Flame and Heat Test on a 35/65-charged MSA FireHawk M7 Air Mask SCBA per NFPA 1981, Standard on Open-Circuit Self Contained Breathing Apparatus (SCBA) for Emergency Services, 2007 Edition.

Subsection 8.11 of this standard directs the Flame and Heat Test. Specific to your question, Step 8.11.5.3.1 directs flame peak temperature readings to be within the range of 1500 to 2102 degrees F. Step 8.11.5.3.2 directs the average mean of all peak temperature readings to be no higher than 1742 degrees F. Per a telephone conversation between Dominion and Intertek held on February 8, 2010, Intertek confirmed that the Intertek operating procedure directs Flame and Heat testing be done according to these NFPA directives.

Contact your MSA sales representative or call the MSA Customer Service Center at 1-877-MSA-3473. They will supply the information you need to meet these require-ments.
The required replacement/overhaul schedule for self-con-tained breathing apparatus from MSA is based on appara-tus usage on an individual basis. The frequency required for SCBA overhaul depends upon how often the appara-tus is used. MSA breathing apparatus must be overhauled based on the actual level of usage of the SCBA, rather than on time alone.

Changes and modifications not expressly approved by the manufacturer could void the user's authority to operate the equipment.
Use in conjunction with personal protective ensembles that provide appropriate levels of protection against der-I mal hazards.
Some CBRN agents may not present immediate effects from exposure, but can result in delayed impairment, ill-ness, or death..
Direct contact with CBRN agents requires proper handling of the SCBA after each use and between multiple entries during the same use. Decontamination and disposal procedures must be followed. If contaminated with liquid chemical warfare agents, dispose of the SCBA after decontamination.
The respirator should not be used beyond 6 hours6.944444e-5 days 0.00167 hours 9.920635e-6 weeks 2.283e-6 months after initial exposure to chemical Warfare agents to avoid possi-bility of agent permeation.
FAILURE TO FOLLOW THE ABOVE ITEMS IN ADDITION TO ALL ESTABLISHED CBRN PROTECTIVE MEASURES CAN RESULT IN SERIOUS PERSONAL INJURY OR DEATH.
The warranties made by MSA with respect to the product are voided if the product is not installed, used and serviced in accordance with the instructions in this manual. Please protect yourself and your employees by following the instructions.

1. An adequate respiratory protection program must include knowledge of hazards, hazard assessment, selection of proper respiratory protective equipment, instruction and training in the use of equipment, inspection and maintenance of equipment, and med-ical surveillance. [See OSHA regulations, Title 29 CFR, Part 1910.134 (c).]
2. This SCBA may be used only after proper instruction and training in its use as specified in NFPA-1500 and OSHA regulations Title 29 CFR, Part 1910.134.
3. Quantitative fit testing should be conducted to deter-mine proper facepiece size prior to using the respira-tor. A Fit Test Kit (MSA P/N 10044576) is available for conducting quantitative fit tests with the Ultra Elite Firehawk Facepieces. The facepiece donning instruc-tions must be carefully followed when using the respi-rator and when conducting fit tests.
5. The CBRN Firehawk Second Stage Regulator must be flow tested every year and overhauled on a periodic basis. An overhaul kit (MSA P/N 10048942) is avail-able.
