Ohio EPA is in the process of updating its vapor intrusion guidance. Except for the 2016 withdrawal of several chapters of the guidance (mostly dealing with the use of the J&E model), this is the first major revision since the document was released in 2010. Ohio EPA requested comments on the significantly revised draft final version (June 2019) of the guidance, with the comment period ending June 15. For a summary of the most significant changes to the guidance, read more….
Recently, the Ohio EPA released Interested Party versions of some solid waste rules as part of the required five-year rule review process. Most notably, this includes changes to Rule 3745-27-13, or what is commonly known as “Rule 13’. Rule 13 concerns the filling, grading, excavating, building, drilling or mining on property where a solid or hazardous waste landfill has been operated.
The Ohio EPA has also proposed changes to several of the other municipal solid waste rules. Most of those changes are minor, but there are changes to Rule 3745-27-08, “Sanitary Landfill Facility Construction”, as well as a few key changes to a few other rules. For more information on the proposed changes, please read on.
