AZPDES Permit No. AZ0021211

ADEQ proposes to issue an AZPDES renewal permit to discharge pollutants to Waters of the United States to the following applicant, subject to certain effluent limitations and special conditions:


Arizona Game and Fish Department
5000 W. Carefree Highway
Phoenix, AZ 85086

Facility Information

Arizona Game and Fish Department applied for a renewal AZPDES permit for the proposed discharge of up to 2.74 million gallons per day (mgd) of used and treated process water from concentrated aquatic animal production (CAAP) operations from the Tonto Creek Fish Hatchery to Tonto Creek in the Salt River Basin in Township 12 N, Range 12 E, Section 33, in Gila County, Arizona. The Tonto Creek Fish Hatchery is a flow-through raceway CAAP facility that receives spring water from Tonto Springs, the perennial source of Tonto Creek, to produce trout. Used process water undergoes removal of solid debris by a passive separation system followed by polishing to decrease nutrient loading in artificial wetlands prior to discharged to Tonto Creek.
