Dry Well Registration
LEGAL AUTHORITY:
A.R.S. § 49-245-02

CONDITIONS REQUIRING PERMITS, AUTHORIZATIONS OR FILINGS:
The purpose of registration is to minimize groundwater impacts and ensure that only storm
water enters a dry well.
New dry wells must be registered with ADEQ within 30 days of starting operation. Closure
of dry wells must follow ADEQ’s Dry Well Decommissioning Guidelines. Aquifer Protection
Permit (APP) requirements apply to dry wells that drain areas where hazardous substances are
used, stored, loaded or treated or where motor fuels are dispensed. Any dry well that is used
for industrial wastewater disposal either solely or in conjunction with storm water is an
injection well, and an APP is required for operation or closure.
EXEMPTIONS:
Exemption from obtaining an APP for closure can be secured if “clean closure” can be
demonstrated. In addition, certain discharges to dry wells in combination with storm water are
exempt from the APP requirements under A.R.S. § 49-250(23).
FEES:
A $100 fee is charged per dry well registration. APP fees are required if a Type 2 general APP
or an individual APP is required.
AVERAGE PROCESSING TIME:
Registration must be complete within 30 days of the completion of the well. Review time for
the registration varies with the complexity of the submittal.
