Hazardous Waste

On this web page you can find detailed information and guidance concerning the requirements for the management of hazardous waste.  The term “Hazardous Waste” as used here means discarded chemicals and other wastes generated from commercial, industrial, and institutional activities.

DEEP recently passed a new regulation adopting the EPA's 2013 Solvent-Contaminated Wipes Rule.  This rule provides an exemption from hazardous waste requirements for certain solvent-contaminated wipes that meet specified management requirements.  In particular, qualifying wipes may be:  (1) laundered at certain laundry facilities; or (2) disposed of at certain in-state combustion facilities or at out-of-state combustion or landfill facilities meeting the requirements of the receiving state.  A copy of the final DEEP regulation is available on the  Connecticut eRegulations website.  More information about this new rule is available in a DEEP PowerPoint Presentation.  Note:  pursuant to the adoption of this new regulation, the DEEP's fact sheet entitled "Industrial Rag Handling" is no longer valid, and will be replaced.
