The City of Chandler operates a stormwater program that describes prohibited discharges and public reporting procedures [1].

How to document a suspected discharge

  • Note the date, time, and weather conditions when you observed the discharge.
  • If safe, collect vehicle information or business names related to the source for the report.
Do not attempt to stop a hazardous spill if it risks personal injury; call emergency services.
