Clean Water Act - Exception or Variances

The video tutorial explains how exceptions or variances from the Clean Water Act's requirements can be requested. The EPA grants two primary variances: economic justification and process justification. Economic justification involves adjusting standards based on a firm's financial ability to implement the best available technology for reducing pollution. Process justification, or fundamentally different factor variance, considers unique operational or cost factors not accounted for in the original guidelines. Both variances aim to ensure pollution reduction while considering economic and operational constraints.

How does the EPA adjust standards based on a firm's economic ability to implement technology?

Discuss the difference between economic justification and process justification in the context of the Clean Water Act.
