10. At least 30 days prior to commencing seeding operations each year (after the first
year), the permittee shall invite representatives from all of the entities listed above
to receive the annual report to a meeting, open to the public, to explain the
operational plan and answer questions.

II. Generator operations shall be carefully controlled to minimize artificial increases
in snowfall within the limits of the Town ofOphir, the City of Ouray, and the Town
of Silverton. The operator and project sponsors, in cooperation with the Colorado
Climate Center, Colorado Avalanche Center, and the National Weather Service
shall develop a continuing precipitation monitoring program to systematically
monitor precipitation changes from normal, either through snowpack or stream flow
measurements, and establish a control area that lies within the same weather
patterns as the target area, but is unaffected by the cloud seeding operation.

Following the first year of operation, but no later than the 30 days prior to the
beginning oUhe second year of cloud seeding operations, the permittee shall
propose for consideration by the Director a methodology and a maximum level of
change at specific long term precipitation recording stations as may be available in
or near the Town of Ophir, the City of Ouray, the Town of Telluride, the Town of
Silverton, and other communities in the region beyond which the cloud seeding
operation shall be suspended.

12. The permittee shall cooperate and help coordinate collection of snowfall samples
and provide supporting meteorological data and information should a federal or
state agency or some university's atmospheric science department become
interested in a long term research project to further analyze and evaluate the impacts
in and outside of the target area, including but not limited to:

A. Snowfall sampling using a vertical snow profile system and content analysis
for traces of silver iodide using graphite furnace atomic absorption
techniques,

B. Detailed precipitation evaluation and statistical analysis, and

C. Determination of the exact area covered and the incremental change in
snowpack due to the seeding operation.

13. The State reserves the right to examine and audit the daily logs, books, and records
of the permittee concerning the project which is the subject of this permit for a
period of two years after the termination date of this permit.
