Mr. H. R. Wall E. E. Hall, RA Vice President P. G. Jacques, PI S. R. Gaarder, ICT Gentlemen:
R. Leith, OC This refers to your application of October 5,1962, as revised and supplemented by your letter of April 1,1966, requesting authorization pursuant to Section 20.103(c)(3) of 10 CFR 20 to use respirators in determining the exposure of individuals to concentrations of radio-activa materials in restricted areas.
We have reviewed the information submitted in your application and have concluded that credit may be allowed for the use of respiratory pro-tective equipment subject to the limitations set forth in the attached authorization. The procedures set forth in your application may be followed except to the extent that they may conflict with the conditions of the authorization.
Accordingly, you are hereby authorized, pursuant to Section 20.103(c)(1) and (3) of 10 CFR 20, to make allowance for the use of respiratory pro-tective equipment in conjunction with activities authorized by License No. DPR-6 in determining whether individuals in restricted areas are exposed to concentrations in excess of the limits specified in Appendix B. Table I, Column 1 of 10 CFR 20, subject to the conditions and limita-tions set forth in the attached authorization.
We are considering an amendment to Part 20 to provide generally for the use of respiratory protective equipant.
In the event such amendment to Part 20 is issued, its requirements and limitations will supersede the provisions contained in this authorization.
Sincerely yours, Original Signed by 5/ /66 5/ /66 5/ /66 R.L.Doan R. L. Doan, Director NOIE: See attached Suppl. for Division of Reactor Licensing previous concurrences.

NAY I 91966 Authorization Pursuant to Section 20.103(c)(1) and (3),10 CFR 20 Consumers Power Company (hereinaf ter referred to as "the licensee;') is hereby author-ired, pursuant to Section 20.103(c)(1) and (3) of 10 CFR 20, to make allowance for the use of respiratory protective equipment in accordance with the application dated October 5,1962, as revised by letter dated April 1,1966, in conjunction with activ-ities authorized by License No. DPR-6 in determining whether individuals in restricted areas are exposed to concentrations in excess of the limits specified in Appendix B, Table I, Column 1 of 10 CFR 20, subject to the following limitations:
1.
In circumstances in which adequate limitation of the inhalation of radioactive materials by use of process or other engineering controls is impracticable, the licensee may permit an individual in a restricted area to be exposed to average concentrations of airborne radioactive materials in excess of the limits specified in Appendix B, Table I, Column 1 of 10 CFR 20 provided:
A.
The individual uses respiratory or other appropriate protective equipment such that the total intake, in any period of seven consecutive days by inhalation, ingestion or absorption, would not exceed that intake which would result from breathing the concentrations specified in I.ppendix B, Table I, Column 1 of 10 CFR 20 for a period of 40 hours4.62963e-4 days <br />0.0111 hours <br />6.613757e-5 weeks <br />1.522e-5 months <br />.
B.
The licensee shall advise each respirator user that he may leave the area for relief from respirator use in case of equipment malfunction, physical or psychological discomfort, or any other condition that might cause reduction in the protectioa afforded the wearer.
C.
The licensee maintains a respiret?ry protection program adequate to assure that the objective of Item "A" absvo is met.
Such program sha!! include:
(i) Air sampling and other surveys sufficient to identify the hazard, to evaluate individual exposure, and to permit proper selection of the respiratory protective equipment; (ii)
Procedures to assure proper selection, supervision and adequate train-ing of personnel using such protective equipment; (iii) Procedures to assure the adequata fitting of respirators ar.d the testing of equipment for operability; (iv)
Procedures for maintenance to assure full effectiveness of respiratory protective equipment, including issuance, cleaning and decontamination, inspection, repair, and storage.
(v)
Bio-assays of individuals and other surveys as may be appropriate to evaluate individual exposures and to assess protection actually pro-vided; and (vi) Records sufficient to permit periodic evaluation of the adequacy of the respiratory protective program.
(
2-The licensee has evaluated the. protective equipment (I) and has determined D.
that, when used to protect against radioactive material under the conditions of use to be encountered, such equipment is capable of prdviding a degree of protection ag2jemst equal to the protection factors listed in Table I attached hereto 2
The licensee shall notify, in writing, the Director, Region III, Division of Compliance, U. S. Atomic Energy Consnission, Suite 410 Oakbrook Professional Building, Oak Brook, Illinois 60523, when the respiratory protection program is initiated. Such notification shall be made within thirty (30) days after the date that allowance for the use of respiratory protective equipment is first made.
3.
The licensee shall not assign protection factors in excess of those given in Table I attached hereto in selecting equipment.
(1) In evaluating respiratory protective equipment for use against radioactive materials to assure that thealuipment provides the protection factors listed in the attached Table I, the licensee may accept equipment approved under appropriate test schedules of the U. S. Bureau of Mines to the extent pertinent.
(2) The factors listed apply only to protection against radioactive materials.
Additional precautions may have to be taken to protect against concurrent non-radiation hazards.

For purposes of this authorization the protection factor is a measure of the degree of protection afforded by a respirator, defined as the ratio of the concentration of airborne radioactive material outside the respiratory p o-tective equipment to that inside the equipment (usually inside the face-piece) under conditions of use.
It is applied to the airborne concentration to determine the concentration inhaled by the wearer, according to the following formula:
Airborne Concentration Protection Factor Concentration Inhaled
=
(b) The protection factors apply:
(i) only for individually fitted respirators worn by trained individuals and used and esaintained under supervision in a well-planned respiratory protection program.
(ii) for air purifying respirators only when high efficiency particulate filters and/or sorbents appropriate to the hazard are used.
(iii) for atomsphere supplying respirators only when supplied with adequate respirable air.
3/ Excluding radioactive contaminants that present an absorption or submersion hazard.
4/ Appropriate protection factors must be determined taking account of the permeability of the suit to the contaminant under conditions of use. No protection factor greater than 1000 shall be used except as authorized by the Commission.
. NOTE 1:
Proteccion factors for respirators as may be approved in the future by the U. S. Bureau of Mines according to approval schedules for respirators to protect against airborne radionuclides may be used in lieu of the protection factors listed in this Table. Where additional respiratory hazards other than radioactive ones are present, especially those immediately dangerous to life, the selection and use of respirators shall also be governed by the approvals of the U. S. Bureau of Mines in accordance with their applicable schedules.
NOTE 2: Radioactive contaminants for which the concentration values in Appendix B, Table I of 10 CFR Part 20 are based on internal dose due to inhalation may, in addition, present external exposure hazards at higher concentrations.
