Hazardous Waste Generator Improvements Rule

U.S. EPA’s final Hazardous Waste Generator Improvements Rule was published in the Federal Register (FR) on November 28, 2016. This final rule became effective at the federal level on May 30, 2017.

For those states and territories that are not authorized for the RCRA program (Alaska, Iowa, and the Indian Nations, and the territories Puerto Rico, American Samoa, N. Mariana and US Virgin Islands), the rule went into effect May 30, 2017.

IDEM has been authorized by the U.S. EPA to implement the majority of the federal RCRA Subtitle C hazardous waste management program in Indiana. Indiana's hazardous waste management rules are codified at 329 IAC 3.1 [PDF].

Indiana as an authorized state is required to adopt those provisions in the new rule that are more stringent than the current RCRA generator regulations in order to retain their authorized status. These provisions of the rule will not become effective in states authorized for the RCRA program until states have adopted the rule and become authorized for the new provisions. Indiana has not yet adopted the new hazardous waste improvement rule. The federal rule changes that were published in the FR November 28, 2016, are not currently recognized in Indiana.

The rules that were in place in Indiana prior to the November federal adoption of the hazardous waste generator improvement rule are still in effect and will remain in effect unless specifically changed by, or replaced by the adoption of the new federal hazardous waste generator improvement rule by Indiana. Indiana’s first public notice regarding the adoption of the new rule is expected to be published in the first quarter of 2018.

The U.S. EPA Frequent Questions page about the Hazardous Waste Generator Improvements Final Rule provides additional information.

Opportunity for Small Entities to provide input on the definition of the “Waters of the U.S.”

The U.S. EPA, in coordination with the U.S. Department of Army (the agencies), will hold 11 sessions to give stakeholders an opportunity to provide recommendations on a revised definition of “waters of the United States.” The agencies will hold nine two-hour long teleconferences that will be tailored for specific sectors, plus one that will be open to the general public. The agencies propose holding a webinar for small entities on Tuesday, September 19, 2017, from 1:00 PM to 3:00 PM Eastern Time (ET), and an in-person meeting on Monday, October 23, 2017, from 9:00 AM to 11:00 AM ET at the U.S. EPA’s Headquarters. The meetings will be part of a longer series of pre-proposal stakeholder outreach the agencies will conduct in the Fall of 2017.
