You should submit the Notice of Intent (NOI) at least 30 days prior to the herbicide spraying. We will review the NOI and attachments for completeness and accuracy. After we receive a complete and accurate NOI, we will either deny coverage or send the permittee a notice of coverage (NOC) under the general permit. If we were unable to transmit an NOC to you within 30 days of receipt of the NOI, discharges are authorized under this permit if the NOI has been assigned a valid NPDES general permit tracking number and you have been informed of this tracking number as an authorization to proceed. Coverage under the general permit is not transferable to new facility owners.

A permittee who has submitted an NOI and received a notice of coverage (NOC) under the general permit has the duty to comply with all provisions of the general permit and applicable rules and regulations.
Coverage under this NPDES general permit does not relieve you of the responsibility for damages to surface or ground water. The permittee must notify the division as soon as possible of planned changes in operations and of any change in mailing address. You are responsible for complying with the conditions of the permit, including keeping records and reporting. If the facility experiences any emergency that could impact the waters of the state, they must notify the division as detailed in the general permit.
