If you are below the thresholds described in Step 1, don't submit a notice of intent (NOI) and proceed to Step 3.

Submit the NOI when you know you'll exceed the threshold, such as when you've exceeded in previous years and your planned activities won't change. You must submit an NOI and receive a notice of coverage before you start discharging.

If you discover after you start to discharge pesticides that you will exceed a threshold, you must submit a NOI prior to exceeding the threshold.

  • Keep track of acres treated, linear miles treated, and/or the amount of pesticide applied (tracking is required by the permit).
  • While you remain below the threshold, you can continue to discharge if you follow the requirements of Step 3. However, you must submit an NOI before you exceed the threshold or you will be in violation of the permit.

If you discharge pesticides in waters of the state in response to a declared pest emergency situation, you have immediate coverage under the permit, but must submit an NOI within 30 days of the declared emergency. See Section 6 of the permit for the full definition of “declared pest emergency situation.”


The application fee for this permit is $1,240. The fee will be reassessed each time the permit is reissued (generally every five years). There is an annual fee after coverage is received of $345, and invoices are usually sent in February or March.

Administrative changes

To change the information ownership, address or contact information submitted on the NOI, submit a modified NOI at least 10 days before the planned change. Use the permit change request form to make the changes with no additional fee.

You may be unaware of all the areas that will receive pesticide treatment when you submit the NOI. Submit the best information you have. More precise information should be recorded as pesticides are applied and submitted with the Annual Report (if applicable).

Changes to information submitted on the annual report, such as treatment location or type and amount of product used, do not require a modified NOI.
