CONDITIONS REQUIRING PERMITS, AUTHORIZATIONS OR FILINGS:
This certification is issued to ensure that federally permitted or licensed activities do not cause
a violation of state water quality standards when an activity may result in a discharge to
waters of the state. ADEQ may also review federal actions for consistency with state-adopted
plans and rules. Each review is specific to the proposed project and the project’s site. A State
Water Quality Certification is necessary before a permit may be issued by a federal agency.
For more information see the Clean Water Act, Section 404.
Contact ADEQ during the preliminary planning for your activity or project to determine if
water quality certification is needed. If certification is needed, you can access online
(http://www.azdeq.gov/environ/water/permits/dredge.html ) or request to be sent an
application form requesting specific project and contact information. Facilities requiring
permit approvals by ADEQ may be subject to a consistency review with the applicable local
and/or regional Water Quality Management Plan.
EXEMPTIONS:
Contact the U.S. Army Corps of Engineers for information about permits under Clean Water
Act Section 404.
