RE: CRYSTAL RIVER UNIT 3 NUCLEAR GENCRATING PLANT On Ha'y 5,1975. the Commission published Appendix I to 10 CFR Part 50 which set fortn numerical guides for' design objectives and limiting conditions for operation to meet the criterion "as low as practicable" regarding releases of radioactive materials in effluents from light-water-cooled nuclear reactors.Section V.B of Appendix I requires the holders of permits or licenses authorizing the operation of light-water-cooled reactors, for wnich application was filed prior to January 2.1971, to file with the Commission by June 4,1976:
1.
Such information as is necessary to evaluate the means employed for keeping levels of radioactivity in effluents to unrestricted areas as low as practicable, including all such information as is required by paragraphs 50.34a(b) and (c) not already contained in his application; and Plans and p'oposed Technical Specifications developed for the 2.
r purpose of keeping releases of radioactive materials in unrestricted areas during normal reactor operations, including expected operational occurrences, as low as practicable.
,In a letter to you from D. Huller dated June 17, 1975, we indicated that tne staff was in the process of developing guidance for licensees required to file information with the Commission under the provisions of Section V.3 of Appendix -1.
This guidance is set forth in Enclosure 1. makes reference to proposed Regulatory Guides 1.AA thru 1.FF.
Tnese guides have been published in draft form and are available in the Commission's public document room. Copies of these guides are being forwarded to you under separate cover. We are preparing additional guidance regarding tne formulation of Technical Specifications to implement Appendix I which will be forwarded to you in the near future. It is recommended that proposals to modify Technical Specifications relatec to Appendix I be deferred pending the completion of this guidance in order to obtain a consistent format for radiological effluent release Tecnnical Specifications.

m' Florida Power Corporation Enclosure 2 provides a list of information we will need to evaluate your facility.
The staff is in the process of determining wnetner plants for wnica application was filed prior to January 2, 1971, can be treated in a mander similar to the treatment given to later plants in the Commission's September 4,1975. Amendment to Appendix I.
On this basis, the information called for by Enclosures 1 and 2 would be sufficient to determine compliance.with the criteria set forth in Section II, paragrapna A, B and C of Appendix I and the design objectives set forth in the Conoluding Statement of Position of the Regulatory Staff in Docket Mi-50-2. which is reproduced as an Annex to Appendix I as amended September 4, 1975. If further information is required to satisfy a plant specific assessment under Section II.D of Appendix I, we will so inform you at a later time.
Within 30 days of the receipt of this letter, you should inform us of the measures you intend to adopt or propose to meet the requirements of paragraph 50.34a. We suggest that a meeting between your staff and the Nhc staff be arranged snortly tnereafter to discuss the submittal of data and methods of evaluation.
Sincerely, Driginal Signed bg W. R. Butler R. C. DeYoung, Assistant Director for Lignt Water Reactors Division of Project Management s

ENCTM2 Additional Infomation Needed from Holders of Pemits or Licenses to Construct or Operate Light-Water-Cooled Reactors for Which Application was Filed Prior to January 2, 1971 1.
Provide the infomation requested in Appendix D of Draft Regulatory Guide 1.BB or 1.CC, as appropriate.
2.
P ovide, in tabular rom, the distances from the centerline of the first nuclear unit to the following for each of the 22-1/2 degree radial sectors centered on the 16 cardinal compass directions.
a) nearest milk cow (to a distance of 5 miles) b) nearest meat animal (to a distance of 5 miles) c) nearest milk goat (to a distance of 5 miles) d) nearest residence (to a distance of 5 miles) e)- nearest vegetable garden greater than 500 ft2 (to a distance of 5 miles) f) nearest site boundary For radioactivity releases from stacks which qualify as elevated releases as defined in Draft Regulatory Guide 1.DD, identify the locations of all milk cows, milk goats, meat animals, residences, and vegetable gardens, in a similar manner, out to a distance of 3 miles for each radial sector.
q 1
3 Based on considerations in Draft Regulatory Guide 1.DD, provide estimates of relative concentration (X/Q) and deposition (D/Q) at locations speci-fled in response to item 2 above for each relear pc at roecified in response to item 1 above.

Provide a detailed description of the meteorological data, models and parameters used to determine the X/Q and D/Q values. Include information conceming the validity and accuracy of the nodels and assumptions for your site aM the representativeness of the meteorological data used.

If an onsite program comensurate with the recomendations and intent of Regulatory Guide 1.23 exists:
a) Provide representative annual and monthly, if available,, joint frequency distributions of wind speed and direction by atnespheric stability class covering at least the most recent one year period of record, preferably two or nore yea"s of record. Wind speed and direction should be measured at levels applicable to release point elevations and stability should be detemined from th'e vertical i
temperature gradient between measurement levels that represent corr-l ditions into which the effluent is released.
b) Describe the representativeness of the available data with respect to expected long-tem conditions at the site.

c) Provide a description of the meteorological measurements used for collection of the data presented. This description should include e
the location of the sensors with respect to the power plant (s) and other prominent topographic features (including buildings) and accuracy of the instrumentation.
d) Provide a comitment to establish a program to meet the reccmendations and intent of Regulatory Guide 1.23, or provide sufficient justifi-cation to allow the present program to remain uncranged.
7 Describe airflow trajectory regimes of importance in transporting effluents to the locations for which dose calculations are made.
