What are approval certificates?
Approval certificates are issued as the formal approval document for a project. The certificates specify the approval, listing any restrictions and stipulating any conditions of the approval.

The Water and Wastewater Treatment Program issues several different types of approval certificates as follows:
- Approval To Construct with Stipulations - Issued after the engineering design review is complete and prior to the start of construction of or modifications to the facility or system.
- Interim Approval To Construct with Stipulations - Issued after the engineering design review is complete and prior to the start of construction or modifications being made to the facility or system. This is a special case of an Approval To Construct that is usually issued so that equipment may be pre-purchased or construction may be completed in phases for time constrained projects.
- Approval to Commence Operations with Stipulations - Issued after construction is complete to allow start-up of a facility or system to commence. This approval is usually issued for a facility or system which utilizes a complex treatment process or system that is required to be validated prior to the facility or system being placed into full operation.
- Approval of Construction with Stipulations - Final approval after construction is complete, start-up and validation testing is complete, an Engineer's Certificate of Completion has been submitted, as-built design drawings have been submitted, an Operations and Maintenance manual has been submitted and approved, and all Approval to Construct and/or Interim Approval to Construct stipulations have been satisfied.
- Approval of Blending Plan with Stipulations - Issued for blending plans which do not involve construction.
- Approval to Proceed with Stipulations - Issued to allow implementation of a proposed plan to proceed. For some plans an authorization letter may be issued in lieu of an Approval to Proceed certificate.
- Approval to Transfer Ownership - Issued as a letter authorizing transfer of ownership of the facility or system.
- Approval to Decommission with Stipulations - Issued after the engineering design review is complete and prior to the start of demolition of the facility or system.
- Approval of Decommissioning with Stipulations - Final approval after demolition is complete, demolition test reports, water quality analyses and remediation reports have been submitted, an Engineer's Certificate of Completion has been submitted and all Approval To Decommission stipulations have been satisfied. This approval may be issued as a letter acknowledging the closure of the facility or system.

The particular approval certificate that is issued will depend on the type of project being approved and whether or not a phased approval is being implemented. For more information, please call 602-372-2861.
