Setting water quality standards (also known as “ambient water quality criteria, or AWQC”) is one of three elements of a typical State water pollution control program under the Clean Water Act.
- Designating uses of water bodies
- Establishing water quality standards to meet designated uses
- Waste discharge permit / NPDES permits
States will also have policies or rules that are used to assure that water bodies that do not meet their water quality standards (“impaired waters”) are brought back into compliance, and policies or rules to assure that water bodies currently meeting standards are not allowed to be significantly degraded (“antidegradation or nondegradation policy”).
Caltha LLP provides expert consulting services to public and private sector clients nationwide to address water quality standards, wastewater permitting and assessing potential impacts of chemicals in the aquatic environment. Caltha is often asked to participate as a “specialty consultant” on larger project teams, bringing our expertise in water quality standards and setting of NPDES permit limits.
