Hazardous Waste Generator Improvements Rule

U.S. EPA’s final Hazardous Waste Generator Improvements Rule (HWGI) was published in the Federal Register (FR) on November 28, 2016. This final rule became effective at the federal level on May 30, 2017. However, the HWGI rule will not be effective until it is adopted as a state rule in Indiana, which will not happen for many months. The IDEM Featured Topics page provides more information.

Extension of Comment Period for the Definition of “Waters of the United States” – Recodification of Pre-existing Rules

U.S. EPA and the U.S. Army have extended the comment period by 30 days for the proposed first step of the review of the definition of "waters of the United States" to provide additional time for stakeholders to weigh in. On August 16, 2017, the U.S. EPA Acting Assistant Administrator for Water, Michael Shapiro, along with Mr. Douglas Lamont, senior official performing the duties of the Assistant Secretary of the Army for Civil Works, signed the Federal Register notice extending the public comment period, which published on August 22, 2017. The comment period, as now extended, will close on September 27, 2017. The proposed rule was signed by the Administrator and Mr. Douglas Lamont, senior official performing the duties of the Assistant Secretary of the Army for Civil Works, and posted to the U.S. EPA website on June 27, 2017, and published in the Federal Register on July 27, 2017. When finalized, the proposed rule would replace the 2015 Clean Water Rule with the regulations that were in effect immediately preceding the 2015 rule. The public can submit comments, identified by Docket ID EPA-HQ-2017-0203, at the regulations.gov website.

Common Violations for Underground Storage Tank (UST) Facilities:

The most common violations for petroleum Underground Storage Tank (UST) facilities in 2016, involved: failure to provide leak detection for USTs, failure to have and provide proof of financial responsibility, failure to submit notification for USTs to IDEM, and failure to maintain proper release detection methods for piping. In addition, an owner of an under groundunderground storage tank, or an operator needs to maintain accurate and current records and be able to produce these records upon IDEM request. Following are Indiana Administrative Code (IAC) citations for each requirement and the Indiana Department of Environmental Management’s (IDEM’s) recommendations for avoiding these and other common environmental violations.

New Definition of Solid Waste (DSW):

The U.S. EPA published a final rule that went into effect July 13, 2015, which revises several recycling-related provisions associated with the definition of solid waste (DSW), which is used to determine hazardous waste regulation under Subtitle C of the Resource Conservation and Recovery Act (RCRA).

Note: IDEM adopted this new DSW rule language by reference in its entirety. A pending DC Court of Appeals ruling regarding portions of the EPA’s 2015 Definition of Solid Waste may affect the new requirements for Indiana’s regulated community differently than outlined below.

Solvents in the Workplace

The U.S. EPA has released a new guidance document, entitled, Solvents in the Workplace – How to Determine If They Are Hazardous Waste [PDF].

Solvents are used in the workplace for many different purposes and once they are spent or left unused and destined to be disposed, making hazardous waste determinations can sometimes be a challenging task. This e-enterprise user-friendly guidance walks through a series of questions and answers that will help a facility determine if it may have generated a hazardous waste solvent. The guidance provides information to assist a facility in recycling or reusing its solvents which could reduce its waste management costs and the nation’s need for virgin materials. Also, at the end of the document, there are a number of questions the U.S. EPA has answered through the years involving hazardous waste solvents.
