Effective July 1, 2022, the Oklahoma Department of Environmental Quality will begin assessing customers a merchant fee in the amount of 2.25% of the amount due if paying via credit or debit card.

Additionally, a portal fee of $2.00 will be charged for each transaction paid by a credit or debit card.

For questions regarding the above-referenced transaction fees or to inquire about payment options, please email or call (405)702-1130.

DEQ also accepts checks, money orders, and cash.
However, the State Environmental Laboratory does not have a cashier. Any person paying with cash will have to take an estimated charges report to the second floor cashier. This will require passage through security. The receipt of payment must then be returned to the laboratory sample receipt area as proof of cash payment.
