DEEP's Waste Engineering & Enforcement Divsions ("WEED") has responded to a number of issues that have arisen as a result of the COVID-19 pandemic.  For information on hazardous waste issues, see below and visit the DEEP's Materials Management COVID-19 web page.  For COVID-19 information on other DEEP programs, visit the Main DEEP COVID-19 web page.

HAZARDOUS WASTE GENERATORS:  Generators have contacted WEED asking what to do if it is impossible to comply with certain hazardous waste generator requirements due to the partial or complete shutdown of their facility during the COVID-19 pandemic.  WEED responded with an email providing guidance for hazardous waste generators that may not be able to comply with requirements such as generator accumulation time limits and weekly container storage area inspections.  Further guidance will likely be forthcoming on this topic.

HAZARDOUS WASTE TRANSFER FACILITIES:  A ten-day transfer facility in Connecticut inquired what to do if it is impossible for them to comply with their 10-day storage time limit due to delays in shipment caused the COVID-19 pandemic.  WEED sent an email providing guidance to this facility regarding this issue.

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.
