How to Pay Your Fees

The dam owner of record is responsible for paying all fees.

Fees must be paid by check or money order payable to the Department of Ecology and mailed to:

Department of Ecology
Cashiering Unit
P.O. Box 47611
Olympia, Washington 98504-7611

See our payment page at: http://www.ecy.wa.gov/services/fs/payment.html

Fee balances are due within 45 days after Ecology mails your invoice.  Ecology considers your fees as delinquent if we do not receive them by the due date.  If a check is returned for insufficient funds, we consider the invoice unpaid.

  • Periodic inspection fees are billed annually.
  • Construction fees are a single amount billed for a specific project. Construction permit fee payment procedures allow dam owners to make an initial payment of $1,977 for construction of a new dam or modification of an existing dam or project. Ecology will then bill the unpaid balance.

Ecology may issue an enforcement order to dam owners with delinquent accounts, or refer the account for collection.

Paid fees are NOT refundable.
