Proposing new rules and amendments to existing rules is a regular activity conducted by Ohio EPA in response to laws passed by the General Assembly and federal rule requirements. The Agency is also required by state law to review its rules at least once every five years to ensure their continued need and relevance. During the Ohio rule-making process, rules are in one of four phases: early stakeholder outreach; draft; proposed; and effective. Electronic versions of rules in each of these various phases may be viewed by clicking on the appropriate tabs on this page.
In addition to adopting rules and laws, DDAGW adopts both policies and guidance documents. The purpose of a policy is to clarify and explain specific aspects of regulations (OAC) and law (ORC) so Ohio EPA and external parties have a common understanding of how environmental regulations are carried out in Ohio. Policies promote consistency and provide savings of both technical and administrative staff resources when dealing with the application of rules. Guidance documents provide information, suggestions and recommendations on possible or acceptable methods that may be used to meet or to achieve compliance with rules.
As of Jan. 1, 2012, Ohio EPA will conduct early stakeholder outreach in response to requirements of Executive Order 2011-01K. This outreach ensures stakeholders are brought into the rule process as early as possible.
There are currently no documents available for review or comment.
