'k REQUEST FOR ADDITIONAL INFORMATION BIG ROCK POINT NUCLEAR STATION DOCKET N0. 50-155 Based on examination of the results of the meteorological studiesU 1.
performed at the Big Rock Point site, it appears that measurements from the 256-foot meteorological tower may be representative of atmospheric transport and diffusion conditions only at the lake shore-line, especially during onshore wind conditions. Although these data may represent the conditions into which gaseous effluents are eleased from the stack, they may not be representative of atmos-pheric transport and diffusion characteristics further inland (e.g. at or beyond the site boundary).
Provide sne following information:
Indicate whether calculated relative concentration (X/Q) a.
and relative deposition (D/Q) values at various inland receptor locations based on measurements from the 256-foot tower could be substantially underestimated.
b.
Discuss possible modifications to the available data to more adequately describe transport and diffusion conditions at and beyond the inland site boundaries.
2.
Explain why the two-year period (February 1961 - February 1963) constitutes the best available meteorological data, especially considering that these data are over thirteen years old.
Discuss -
any meteorological data collected at the site since May 1963 and indicate if these data have exhibited any characteristics that could result in significant variations of calculated X/Q and D/Q values based on the 1961 - 1963 data.
3.
The 256-foot onsite meteorological tower has not been installed since May 1963.
Provide the following information:
a.
The rationale for discontinuing measurements from the tower and the date that tower operation was discontinued.
b.
Describe the onsite meteorological measurements program in operation since May 1963, and compare this program to the recomendations and intent of Regulatory Guide 1.23.

2-A c.
Discuss proposals for upgrading the onsite meteorological measurements program to collect representative meteorological data for assessing gaseous effluent releases. Compare these proposals with the recomendations and intent of Regulatory Guide 1.23.
