DEQ Guidance

Guidance may include memoranda, manuals, policy statements, interpretations of law or rules, and other material that are of general applicability, whether prepared by the agency alone or jointly with other persons. In some cases, guidance consists of recommended best management practices. Guidance does not have the force and effect of law or rule. Rather, it is designed to serve as primary reference tools to assist those impacted by agency actions to comply with laws and rules. Access major guidance documents below.
