observation of the operator/applicant. Under ideal conditions, the operation of the hail cannon
will commence ten (10) minutes before the expected arrival of the hail'producing cloud over
the target area and will continue operation until the hail-producing cloud(s) has fully passed
over the target area, The decision to commence operation of the hail cannon will be made by
the operator/applicant and will be based upon the operator/applicant's visual observations and
best judgment as to cloud size, speed, and likelihood of producing hail. The time interval of
each operation is largely detennined by wind velocity and magnitude of each hail stonn, In
deciding whether to commence operations, it is expected that the operator/applicant will likely
have fifteen (15) to sixty (60) minutes to observe suspect clouds and monitor their fonnation,
movement and speed toward the target area, As stated above, operation of the hail cannon
will tenninate upon departure of the hail producing cloud from the target area, The applicant
expects that the hail cannon is likely to be operated on approximately thirty (30) different
occasions during each growing season, with each operation having a duration of
approximaJ~ly.sixty (60) minutes, depending upon.the.size-and-intensityofeach hail stonn,

4, How the proposed proiect is designed to provide and offer oromise of providimz economic
benefit to the target area (applicable to commercial oroiects only):

Utilizing the method set forth in this application, the applicant seeks to control/reduce hail
precipitation so as to alleviate the loss to growing crops and improvements (Greenhouses)
within the target area, thereby furnishing an economic benefit both to the applicant (whose
crops and improvements are protected) and the people of the State of Colorado, preserving
the jobs of those who deal in the harvesting and marketing of-these crops, The State of
Colorado is further benefited by protecting its reputation as a producer of fine tomato crops
so that the buyers throughout the United States may rely upon applicant and other Colorado
producers for their supplies of these products, The ability of Colorado producers to
consistently furnish these products free of hail damage will serve to substantially increase
Colorado's position as a viable econo!!!ic producer of these crops,

5, Indicate how the proposed proiect is reasonably expected to benefit both persons living in the
target area and the people of Colorado,

Please see applicant's response to Interrogatory Number 4 immediately above,

6, Indicate how the proposed oroiect is scientifically and technically feasible,

The technology described and the methods set forth in this application have been in use in
other locations for a considerable period oftime and have been shown to control the hazard
of hail inside a circle of a radius of 500 meters surrounding the hail cannon, Identical hail
cannons have been installed and operated in Center, Colorado by Southern Colorado Fanns,
Inc,; in Ault, Colorado by Moson Bros, Co,; in Fort Lupton, Colorado by Villano Bros,
Farms, Inc,; and in Brighton, Colorado by David Petrocco Farms, Inc, [please see State of
Colorado Weather Modification Pennit No, 96-5, issued July 18, 1996, and preliminary
