Liability may not be imposed upon an agricultural producer for costs of active cleanup, or for any damage associated with or resulting from the detection in ground water, of a pesticide if the applicator has complied with label instructions and other precautions for application of the pesticide and the applicator has a valid appropriate applicator's certification. Compliance with these requirements may be raised as an affirmative defense by an agricultural producer.
