Docket No. 50-285 (2)
Letter from FEMA (R. Leonard) to OPPD (W. C. Jones) dated June 24, 1985
Dear Mr. Martin:
Fort Calhoun Scenario The Omaha Public Power District received Reference (2) which requested addition-al infomation by July 3,1985, with regard to the subject scenario for the 1985 exercise. The District has evaluated the request and find that we are unable to provide the additional infomation due to the quantity of infomation requested and the short period before the 1985 exercise. Development of the kind of infor-mation requested is a time-consuming task requiring outside agency procedures and detector efficiencies not readily available to the District at this time.
The content of the scenario was discussed during two meetings between OPPD, FEMA and the State of Iowa, and during meetings between OPPD and the States of Iowa and Nebraska. Based upon the results of those meetings, we believe that the scenario, a copy of which FEMA received on June 12, 1985, is in accordance with the requirements and contains the information necessary to conduct a satisfac-tory demonstration of the Neraska and Iowa State Emergency Plans.
The off-site data presented in the District's 1985 scenario is sufficient to i
define the plume by the District's r.urrent methodology. The District's method for definition of the plume is to collect air samples, measure and record dose rate results at the established monitoring locations in those sectors projected to be affected by the plume, as well as in those sectors adjacent to the affect-ed sectors. The states of Iowa and Nebraska use this same method which is imple-mented in the event of an accidental release of radioactive material to the envi-ronment.
In addition, the format and content of the off-site data were reviewed and approved by representatives of both the State of Nebraska and the State of Iowa.
The fomat and content (mr/hr and uCi/cc) of the off-site data presented are believed to be more useful for decision making than raw field measurement data.

Mr. R. D. Martin July 5,1985 Page Two Field data is evaluated by experienced supervisors prior to revision of PAR's and is not the responsibility of the field monitoring teams.
Data on ground deposition, prestsnably of nuclides classified as particulates, were not presented because the 1985 exercise scenario does not contain release of particulates. Therefore, data on ground deposition is not appropriate for this event.
The request that radiofodine data be presented as field measurement data (cpm) rather than field result data (uCi/cc) cannot be fulfilled due to technically qualified manpower being applied to other tasks which must be completed prior to and in support of the 1985 exercise.
With regard to the presentation of field data via isopleth maps, this iten also cannot be accomplished due to the allocation of manpower to other tasks, as stated above.
In addition, the District does not have the facilities required to generate the quantity of isopleth maps which would be needed to provide a revised plume position every fifteen (15) minutes for the duration of the exer-cise.
The final item is with regard to meteorological forecast infonnation availabil-ity to State and local operations centers. This information will be passed to the State and local centers in a timely manner through consultation between the respective organizations at an established level of management.
The District believes that the infonnation requested may enhance the realism of an emergency exercise if it is handled and presented properly. However, gener-ation of the requested infonnation is a very time-consuming task; time which is not available prior to the 1985 exercise.
In conclusion, the District believes the 1985 scenario contains the necessary elements to demonstrate the emergency response capabilities of the exercise participants.
Si ncerely,
b R. L. Andrews Division Manager Nuclear Production RLA/CWN/rh
