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 is currently nothing available for comment.

Ohio EPA considers comments received during interested party review and makes changes to the rules as appropriate. These rules are then proposed and filed with the Ohio General Assembly's Joint Committee on Agency Rule Review (JCARR) and other agencies as required by Ohio Revised Code section 119.03. Another opportunity for public comment is offered. More information about proposed rules is on the Register of Ohio website.
The following proposed rules have been filed with JCARR:
The Division of Drinking and Ground Waters (DDAGW) has proposed revisions to several rules in OAC Chapter 3745-81 (primary drinking standard and lead and copper rule) and OAC rules 3745-89-08 (Laboratory Certification rule) and 3745-96-02 (Consumer Confidence Reports rule) to Joint Committee on Agency Rule Review (JCARR). The revisions incorporate provisions of Ohio House Bill 512 (effective in Ohio Revised Code § 6109.121). These rules address lead notification and monitoring for community water systems and nontransient noncommunity water systems.
Ohio EPA will be holding a public hearing on the revised rules on March 6, 2018, at 10.30 am at Ohio EPA Central office, Columbus, Ohio. Please see the public hearing notice, response to comments, proposed rule language and the Business Impact Analysis (Linked below) for information on the changes and how to submit comments/attend the hearing.
