It is the policy of the act and the board to encourage informal, practical, result-oriented resolution of alleged violations and actions needed to prevent damage to public resources. It is also the policy of the act and the board to provide, consistent with the principles of due process, effective procedures for enforcement. It is the policy of the board to use a progressive approach to enforcement, and civil penalties should be one of the least used enforcement mechanisms; such an approach usually begins with consultation and voluntary efforts to achieve compliance while generally reserving civil penalties to more serious infractions. This part of these regulations provides the following enforcement procedures: Informal conferences; notices to comply; stop work orders; corrective actions by the department; civil penalties; injunctions and other civil judicial relief; and criminal penalties. Civil penalties shall be appropriate to the violation or its potential to damage public resources.
