2. Classification System
Class SA waters allow impoundments and very restricted discharges, so the risk of degradation while quite small, does increase since there is some small human intervention in the maintenance of the ecosystem.
Class SB have fewer restrictions on activities but still maintain high water quality criteria.
Class SC have the least restrictions on use and the lowest (but not low) water quality criteria. Class SC waters are still good quality, but the margin for error before significant degradation might occur in these waters in the event of an additional stress being introduced (such as a spill or a drought) is the least.
3. The Hierarchy of Risk in Determining Water Classification
The Water classification system should be viewed as a hierarchy of risk, more than one of use or quality,
The risk is defined as the possibility of a breakdown of the ecosystem, and loss of use due to either natural or human-caused events.
Ecosystems that are more natural in their structure and function can be expected to be more resilient to a new stress and to show more rapid recovery. Classes AA, GPA and SA involve little risk since activities such as waste discharge and impoundment are prohibited. The expectation to achieve natural conditions is high and degradation is unlikely.
