C. Directives and Guidelines
Inherent in the development of any study plan is the
knowledge that there are certain directives and
guidelines that dictate the scope and direction of
study. The GCES Phase II Environmental Study Plan is
no exception. The directives and guidelines used in
this plan are as follows:
1. The Executive Review Committee agreed, in
concept, with the concerns raised in the
INTERIM Technical Integration Team memor-
andum (Appendix 1, page 4).
2. The Executive Review Committee has
directed that the environmental technical
studies be designed and carried out in
such a way as to yield a 1175% Comfort
Level" of decision. The level of risk
associated with decision-making is a
function of the length of time of study,
the conditions during the study relative
to the entire period of concern, the
level of understanding prior to study
initiation, and the intensity and quality
of effort during the period of study.
Risk assessment is the responsibility of
scientists who carry out the technical
studies, but risk management is the role
of policy makers.
3. The Executive Review Committee directed
that time, dollars, access, and required
flows be estimated and the parties
responsible for each category of study be
identified.
4. The attainment of the 75% level of risk
requires that the uncertainty (error) in
conclusions drawn from results of initial
studies must be defined as closely and
quantitatively as possible. An assess-
ment of the cumulative and interactive
uncertainty will also be required.
5. In order to achieve a 75% level of risk
on certain management decisions, the
decisions for which a lower level of risk
(an a higher level of certainty) is
needed must be presented to the study
planning team.
