a meetingr:as held en
'2y 19, 1970 to discues the en-s ite me tec-rology data and anal:..' is for "":I Unit.:c. 1.
Attending cere K. Wocd ea rd (of Picia rd-Lcie, rep resentin; 'le t-f.d), Dr. Is aac Vande rhe.cr (of ESSA), and Ross, ':ichan, and Spickler of DP.L.
Woodard stated that the percentage calms was about C.,
based en a'c c u t 11,000 measurements in 2 jears.
- o b reakde.:n en day-night calm dis tribution was immediately availab le.
The data have been reduced to :/Q t,and dose) vs nrobability of occurrence with sector (22 1/2') as a :arameter.
In this analysis an e:.: tended exclusicn dis tance ins used (greater than 2000') fertaose directicns, generally 'tes tward, that it appeared faasibla.
':o mentien of this type of boundarv extension is at present in the FS! '.
In a rough approx.imation to a 1-hour probability model, L:here the calms *. tare classi led as rasquill G, in/sec, it appears that 5 x 10_,
3 sec/m is the five-percentile figure.
.ie us ed 5 x 10's e c /i n' a t the CP review for 2-hour dose calculations.
We suggested f.t data be gathered to enable Pasquill category classification. Another metecrology tower is being constructed andit ins truments 'eill be ins talled.
We asked for revisions to Tables 2-10 through 2-16 cf the FSAP. se that calms wculd be accounted for.
- 'e also asked for a clarificatier of the exclusion area boundary.
