When is a MAG 208 certification required?
MAG 208 certification is designed to address 2 key issues related to wastewater treatment plants. The MAG 208 Water Quality Management Plan identifies the following types of wastewater treatment plants as requiring approval:
- Plants greater than 2.0 million gallons per day and those with a discharge requiring an NPDES permit or AZPDES permit which are not specifically identified in the MAG 208 Plan would be required to go through a formal 208 analysis or amendment.
- A small plant is a reclamation plant with an ultimate capacity of 2.0 million gallons per day (mgd) or less with no discharge requiring an NPDES or AZPDES permit.

Additional information about the review and approval process can be found in the MAG 208 Water Quality Management Plan (PDF).
