Question

Describe the difference between technology based effluent standards and water quality based effluent standards under the Clean Water Act. Also, indicate which of these two different standards is likely to be controlling on a small stream designated as a cold water fishery and why.

Answer 1

Explanation:

Technology-based:

1.As the name implies technology, no technology will be clarified about it. It only depends on the variables, which describes them.

2. That is based on a single facility's findings.

3. It takes into account the contaminants type and volume, and their equations to monitor them.

4. This is reserved for city or urban wastewater treatment plants only.

5. It takes into account the pH, need for oxygen and the suspended solids.

Water quality based on:

1.This is enforced if there is a need to apply stricter limits to pollutants that are not pleased with the limits of technology.

2. All basing on water quality was risk-based.

3. They placed some less importance on the technologies which is used in the technology based limit.

Water quality dependent restrictions are used as cool water fishery for streams.

The act on clean water will also include bodies of water belonging to wildlife, agriculture and others. The law also included that the physical chemical and biological variables of all the state water bodies must be controlled by these water quality based limits.
