Delegated Authorities

ADEQ may authorize political subdivisions, such as county or city agencies, to exercise certain environmental regulatory functions, powers or duties by a provision of law. These delegated local authorities may have standards of compliance that are stricter than those of ADEQ but not less.

Emergency Response

Emergency Response Hotline: (602) 771-2330 or (800) 234-5677 - Toll Free

The ADEQ Emergency Response Unit is on call 24 hours a day, seven days a week, to ensure that all environmental emergencies are promptly addressed. The Unit works to minimize injuries, deaths, property damage and threats to human health and the environment from chemical spills, fires, explosions and other pollutant releases by stabilizing emergency incidents through its role as the environmental support agency of the State of Arizona Emergency Response and Recovery Plan .

For non-emergency environmental concerns or situations that you believe threaten the environment, such as a trash dump, discarded waste tires, or colored water in a stream, please File a Complaint.

Violation versus an Emergency?

An environmental violation occurs when an activity or an existing condition does not comply with an environmental law or regulation. Environmental violations can include (but are not limited to):

  • Smoke or other emissions from local industrial facilities;
  • Tampering with emission control or air conditioning systems in automobiles;
  • Improper treatment, storage, or disposal of hazardous wastes;
  • Exceedances of pollutant limits at publicly-owned wastewater treatment plants;
  • Unpermitted dredging or filling of waters and wetlands;
  • Any unpermitted industrial activity; or
  • Late-night dumping or any criminal activity including falsifying reports or other documents.

An environmental emergency is a sudden threat to the public health or the well-being of the environment, arising from the release or potential release of oil, radioactive materials, or hazardous chemicals into the air, land, or water.

Examples of environmental emergencies include:

  • Oil and chemical spills;
  • Radiological and biological discharges;
  • Accidents causing releases of pollutants.

A Global Positioning System (GPS) is a space-based radio-navigation system. GPS provides users with accurate information about their position and velocity, as well as the time, anywhere in the world and in all weather conditions.

GPS, formally known as the Navstar Global Positioning System, was initiated in 1973 to reduce the proliferation of navigation aids. GPS is operated and maintained by the United States Department of Defense. By creating a system that overcame the limitations of many existing navigation systems, GPS became attractive to a broad spectrum of users. GPS has been successful in classical navigation applications, and because its capabilities are accessible using small, inexpensive equipment, GPS has also been used in many new applications.

GPS determines location by computing the difference between the time that a signal is sent by a satellite and the time it is received by a GPS receiver. GPS satellites carry atomic clocks that provide extremely accurate time. The time information is placed in the codes relayed by a satellite so that a receiver can continuously determine the time the signal was broadcast. The signal contains data that a receiver uses to compute the locations of the satellites and to make other adjustments needed for accurate positioning. A receiver uses the time difference between the time of signal reception and the broadcast time to compute the distance, or range, from the receiver to the satellite. A receiver must account for propagation delays, or decreases in the signal's speed caused by the ionosphere and the troposphere. With information about the ranges to three satellites and the location of satellites when signals are sent, a receiver can compute its own three-dimensional position.
