Enforcement & Settlement Agreements

​Share this page​

​​​​​​​​​​​​​​​The City of Phoenix ensures that regulated industrial users comply with Federal, State and City laws. To assist with investigating and responding to instances of industrial user noncompliance, the City ​of Phoenix has developed an Enforcement Response Plan (ERP) that outlines available enforcement actions. Enforcement responses can range from an informal verbal warning, to a formal Notice of Violation (NOV), or the assessment of penalties, or in rare situations the termination of City services.​

Depending on the severity, frequency, and other conditions related to one or more violations, a regulated entity could be placed in a state of Significant Noncompliance (SNC).

​A list of companies in SNC is published in the newspaper annually.

Pretreatment Settlement Agreements

A Pretreatment Settlem​ent Agreement (PSA) is an ​​out-of-court settlement which legally describes the details of a negotiated agreement. A PSA stems from a Show Cause Meeting during which the City and an industrial user negotiate civil penalties and resolve disputes pertaining to violations of a Wastewater Discharge Permit and/or Federal, State, and Local wastewater discharge regulations.
