required by Section 3.1.10 (6) of the rule.
CORRECTIVE ACTION:
• Implement approved weed control plan and provide proof to the Division that this
has been done. If a weed control plan is not already in place, the operator shall
develop a weed control and management plan in accordance with Section 3.1.10 (6)
of the Rule. This plan should be developed in consultation with the county extension
agency, or weed control district office and should include specific control measures
to be applied, a schedule for when control measures will be applied and a post-

Division as a Technical Revision to the approved plan with the appropriate
Technical Revision fee of $216.00 by the corrective action date.
