When the “modern” Clean Water Act was passed by Congress in 1972, it had to override a Presidential veto. One of the most controversial elements of the Act was a prohibition of all discharges to the Waters of United States, unless the discharge was specifically allowed by a National Pollutant Elimination System (NPDES) permit. Unlike many environmental Acts passed since, there is no “deminimis” discharge to surface waters allowed under the Clean Water Act.
Most States have been delegated to authority to issue NPDES permits (some States use a different acronym). The NPDES permit specific requirements that must be met. During the permit application process, the permitting agency can require the discharger perform studies or additional monitoring to assist the agency in developing appropriate permit conditions.
Caltha LLP provides expert consulting services to public and private sector clients nationwide to address water quality standards, NPDES 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 NPDES permit limits.
