(b) A local plan may take into account the particular needs and uses of the public bodies of surface water to which it will apply, but the plan may not be approved unless the plan meets the minimum standards set by the state plan. The local plan may allow herbicide use if the person proposing to apply the herbicide notifies the governing entity not later than the 14th day before the proposed date of application.
