Eear Mr. Reid:
Three Mile Island Nuclear Statien Unit No.1 Docket Number 50-289 Enclosed please find forty (LO) copies of cur respense to Enclosure 2 of your letter of February 18, 1976 concerning Appendix I to 10 CFR Part 50.
'4e have sent under separate cover six (6) ecpies,f a docunent entitled, "Mewrological Infer =atien and Diffusion Estimates to Conform with Appendix I Requirements". This data was uced to per#om the Appendix ! Analyses for both Three Mile Island Units 1 and 2.
It is our opinion that these submittals answer all cutstanding questions with respect to Appendix I for Three Mile Island Unit 1.
Sincerely,
'i R. C.

Errata Sheet to respcnses to questiens raised in Enclosure 2 of the ITEC's 2-18-76 letter to TMI-l concerning Appendix I The following changes shculd be made to the above referenced document. These errors were inadvertently over looked in the initial printing.
Question 2a - typo change " nearest mile cov...." to
" nearest milk cov...."
Respenses to questions 3, h, 5 and 7 indicate that
=eteorological information is attached. This information was sent under separate cover, GQL 0998.
Ikbh
g RESPL-;25 G OUESTIONS RAISED IN ENCLLedRE 2 OF THE NRC'S 2-18-76 LETTER TO BlI-1 CONCERNING APPENDIX I QUESTION 1 Provide the infor=ation requested in Appendix D of Draft Regulatory Guide 1.BB or 1.CC, as appropriate.
RESPONSE
The analysis submitted on 6/4/76 contains the necessary information required by Draft Regulatory Guide 1.BB.
QUESTION 2 Provide, in tabular form, the distances from the centerline of the first nuclear unit to the following for each of the 22-1/2 degree radial sectors centered en the 16 cardinal compass directions, Nearest mile cow (to a distance of 5 miles) a.
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)2 (to a distance Nearest vegetable garden greater than 500 ft e.
5 miles) f.
Nearest site boundary.
For radioactivity releases from stacks which qualify as elevated releases as defined in Draft Regulatory Guide 1.DD, ide: tify 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.
RESPONSE
See attached Table 2-1.
QUESTION 3 Based on censiderations in Draft Regulatory Guide 1.DD, provide estimates of relative concentration (X/Q) and deposition (D/Q) at locations specified in response to item 2 above for each release point specified in respense to item 1 above.
RESPONSE
)
See Tables 1.3-11A to 1.3-14B of attached Meteorological Information for Three Mile Island Units 1 S 2.
QUESTION 4 Provide a detailed description of the meteorological data, models and parameters used to determine the X/Q and D/Q values.
Include information concerning the validity and accuracy of the models and assu=ptions for yout site and the representativeness of the meteorological data used.
RESPONSE
See Sections 1.1, 1.1.1, 1.1.2, 1.1.3, 1.1.4, 1.2.1, 1.2.2, 1.2.3, 1.3, 1.32 6 1.3.3 and Tables 1.1-1, 1.1-4, 1. 3-2, 1.3-3, 1,3-4 and 1. 3-5 o f attached Meteoro-logical Information for Three Mile Island Units 16 2.
QUESTION S If an onsite program commensurate with the reco=mendations 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 atmospheric stability class covering at least the most recent one year period of record, preferably two or more years of record. Wind speed and direction should be measured at levels applicable to release point elevations and stability should be determined from the vertical te=perature gradient between measurement levels that represent conditions into which the effluent is released.
b.
Describe the representativeness of the available data with respect to expected long-term conditions at the site.
RESPONSE
a.
See Tables 1.1-2 and 1.1-3 of attached Meteorological Information for Three Mile Isinnd Units 1 5 2.
b.
See Section 1.1-4 of attached Meteorological Information for Three Mile Island Units 1 6 2.
QUESTION 6 If recent onsite meteorological data are not available, or if the meteorological measurements program does not meet the recommendations and intent of Regulatory Guide 1. 23 :
a.
Provide the best available meteorological data in the format descri. bed in item 5.a above, b,
Describe the representativeness of the available data with respect to onsite and near site atmospheric transport and diffusion conditio.'s, and with respect to expected long term conditions at and near the site.
1469 415
. QUESTION 6 (Cont'd.)
c.
Provide a description of the meteorological measurements used for collection of the data presented, This description should include 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 commitment to establish a program to meet the recem=endations and intent of Regulatory Guide 1.23, or provide sufficient justification to allow the present program to remain unchanged.
RESPONSE
Since acceptable onsite meteorological data is available for Three Mile Island Unit 1,tthe Applicant will not respond to this question.
QUESTION 7 Describe airflow traj ectory regimes of importance in transporting effluents to the locations for which dose calculations are made.
RESPONSE
See Sections 1.1.5,1. 2. 2 and 1. 2.3 of attached Meteorological Information for Three Mile Island Units 1 5 2.
QUESTION 8 Provide a map showing the detailed topographical features (as modified by the plant) on a large scale, within a 10-mile radius of the plant and a plot of the maximum topographic elevation versus distance from the center of the plant in each of the sixteen 22-1/2 degree cardinct compass point sectors (centered on true north), radiating frem the center of the plant, to a distance of 10 miles.
RESPONSE
See attached Table 8-1 and Figures S-1 through 3-16.
1A69
'16 QUESTICN 9 Provide the dates and times of radioactivity releases from intermittant sources by source location based on actual plant operation and, if available, appropriate hourly meteorological data (i.e., wind direction and speed, and atmospheric stability) during each period of release.
RESPONSE
Since it is our understanding that the first full year of effluent release data is not considered representative, we are enclosing copies of the effluent release data contained in the Semi-Annual Reports for 1975 at Three Mile Island Unit 1.
