This permit authorizes process wastewater discharges from Concentrated Aquatic Animal Production Facilities using flow-through systems, impoundments or recirculating systems.
This permit also authorizes the land application of waste solids produced as part of normal operation, cleaning process or maintenance of facilities such as animal aquaculture and fish hatcheries and preserves.
Flow-through facilities are those diverting water from a river, stream, or spring to supply a continual flow through a series of tanks or raceway. Impoundments include, but are not limited to, ponds, pools, pits, closed cells, tanks, or other structures constructed from earth, concrete, plastic or metal that are used for production aquaculture or as settling ponds or basins used for the collection of solids. Recirculating systems filter and reuse water from the production of aquatic animals.
This permit applies only to the production of fish, crawfish and amphibians. It does not apply to the production of alligators, turtles or other aquatic species unless the department determines a facility’s processes and pollutants discharged are fundamentally similar to the covered species.
