Credit Card Terms of Payment

Information regarding payment methods accepted and limitation of liability



Conditions of Payment for all Payment Types

These Terms of Payment set forth apply between you and the South Coast Air Quality Management District (“South Coast AQMD”) with respect to your payment from South Coast AQMD’s website.  These Terms of Payment shall apply and may not be altered, supplemented, or amended by the use of any other document.

Payments made to this Internet Site are limited to customers who are at least 18 years of age and who are residents of either the United States of America or foreign countries supporting a minimum of 128 bit encryption. South Coast AQMD will NOT accept payments through this website from parties who are underage.  By submitting your payment through this website, you certify that you meet all of the requirements set forth in these Terms of Payment.

Payments Types

Payments are limited to e-checks, American Express, Discover, Visa & Master Card and are the only methods of payment that will be accepted through this website. All payments received by South Coast AQMD are subject to acceptance at South Coast AQMD’s sole discretion.

Conditions of Payment eCheck

These Terms of Payment set forth the terms of the eCheck payment service ("eCheck Service") offered to you through this Site. You may only use the eCheck Service to request an electronic transfer of U.S. funds drawn off U.S. based financial institutions.

Additionally, only a U.S. personal checking account is eligible to use this eCheck Service. The types of accounts not eligible to use this eCheck Service include, but are not limited to, the following:

• Corporate or Business Checking Account
• Brokerage Accounts
• Cashier's Checks
• Credit Card Accounts
• Equity Line of Credit Accounts
• Money Market Accounts
• Money Orders
• Savings Accounts
• Third Party Checking Accounts
• Travelers Checks
• U.S. Treasury Checks

If you wish to use an account other than a personal checking account, you may make your payment by using any of the other methods described in the "Other Payment Methods" section below.

When you request a payment using this eCheck Service, you are authorizing a one-time electronic fund transfer from your bank account to our bank account. Upon receipt of your authorization, we will process it using the Automated Clearing House (ACH) system to debit your U.S. bank account. Once you click the "Process Payment" button, you will not be able to make changes to your payment or to change or revoke your authorization for this payment as it is processed immediately.

You must provide a valid bank account to be electronically debited by us. Both the bank routing number and the bank account number you provide must be correct. If either or both numbers are wrong, your bank may not honor the eCheck payment and return it to us unpaid. You may be charged a returned fee if your eCheck payment is returned. To help avoid any penalties, costs, and returned fees, delays in processing your permit application(s), or rejected application(s), please double-check all data you have entered to ensure its accuracy, as well as the availability of funds in your designated bank account, and that you are using a U.S. personal checking account, before submitting the payment.
