The Stormwater permits program protects surface waters from stormwater runoff in urban areas.
The National Pollutant Discharge Elimination System (NPDES) stormwater permits program comes from the 1972 Federal Clean Water Act and its major amendment the 1987 Water Quality Act. The United States Congress directed the Environmental Protection Agency (EPA) to introduce these regulations to protect surface waters from stormwater runoff in urban areas. Urban stormwater runoff is considered to be one of the leading sources of poor water quality due to its tendency to contain heavy concentrations of pollutants from vehicles, buildings, pavement, industry and other urban sources.
Stormwater Jurisdictions and Regulations
There are two stormwater jurisdictions and regulations that communities and owners need to follow. Construction site owners/operators must satisfy both State and City regulations.
- State Regulations: Information about the Arizona Pollutant Discharge Elimination System (AZPDES) stormwater municipal, construction and industrial programs.
- City Program: Information about the City of Yuma's stormwater program and regulations.
- Colorado River Designation as Impaired Water: In its 2006/2008 303 (d) Impaired Waters list, Arizona Department of Environmental Quality (ADEQ) designated the Colorado River segment in the City as impaired for low dissolved oxygen and selenium. The impairment has been categorized as "Impaired surface waters where a Total Maximum Daily Load (TMDL) analysis is required." The TMDL will be initiated by ADEQ.
To meet the requirements of Part V.A.4 of General Permit Number AZG2002-002, the Stormwater Management Program (SWMP) has been modified, by specifying an "Additional Control Measure" (ACM) to address this designation. The intent of this ACM is to reduce the discharge of 303(d)-listed pollutants from the City's stormwater drainage system to the Colorado River.
One of the prominent features of this designation is the strict requirement of all construction sites that disturb on or more acres and located within 1/4 mile of the River. This requirement calls for Stormwater Pollution Prevention Plan (SWPPP) to be reviewed and approved by ADEQ before start of construction and 7 days interval inspection of the SWPPP Best Management Practices.
