During the first National Corrective Action Conference since 2008, EPA announced its vision, mission, and goals for the RCRA Corrective Action program over the next ten years. The outcome of the 2020 goals, which have driven the Corrective Action program for the last 16 years, was also presented. Were EPA, states, and territories successful in meeting the 2020 goals for Corrective Action? What are the Corrective Action goals for 2030?

What Do the New Generator Improvement Rules Mean for TSDFs?

The Hazardous Waste Generator Improvements Rules became effective at the federal level on May 30, 2017. Ohio’s adoption of these rules are consistent with the federal rules and became effective on October 5, 2020. The rules represent the most significant changes to the generator rules since the program was implemented nearly four decades ago. Refer to our April 2018 article for an overview of the rules as they pertain to generators. But what do these rules mean for a RCRA-permitted TSDF that is also a generator?

New Ohio EPA Explosive Gas Monitoring Rule Promulgated

On October 21, 2020, the Division of Materials and Waste Management of the Ohio Environmental Protection Agency (Ohio EPA) announced that the proposed explosive gas rule for municipal solid waste landfills was filed with the Joint Committee on Agency Rule Review (JCARR). The rule, 3745-27-12 of the Ohio Administrative Code (OAC), which was first enacted in 1988, sets out the requirements for monitoring explosive gas migration at solid waste landfills. The proposed rule submitted to JCARR is substantially different from the 1988 rule. Because more than 50% of the rule was amended, the current rule is being rescinded and the new rule is being promulgated. Read more for summary of changes.

Updated ITRC Incremental Sampling Methodology (ISM) Guidance Released

The Interstate Technology Regulatory Council (ITRC) has released the new Incremental Sampling Methodology (ISM-2) Update Document. As defined by ITRC, ISM is a structured composite sampling and processing protocol that reduces data variability and provides a reasonably unbiased estimate of the mean contaminant concentration in a volume of soil targeted for sampling. The web-based ISM-2 was developed to build on the original 2012 version (ISM-1) and to reflect advancements in technology and share case studies that provide insight into the potential applications, benefits, and challenges of the approach.
