HHW Collection Facilities


This website is for operators of Household Hazardous Waste Collection facilities who seek regulatory guidance from DTSC. The website memorializes questions and comments received from the household hazardous waste collection facility (HHWCF) workgroup and is a product of ongoing communication between HHWCF operators and DTSC staff in an effort to develop a consistent understanding of DTSC hazardous waste control laws and regulations applicable to HHWCF. Guidance posted on this website will be revised and updated periodically.

If you are not a HHWCF and would like to know how to manage hazardous waste from your home or eligible small business, go to the DTSC Household Hazardous Waste Website to find out how and where to manage your household or eligible small business hazardous waste.


Conference Calls are scheduled monthly, on third Thursdays from 10am to 11am. For more information about the conference calls, please sign up for the Household Hazardous Waste Collection Facilities (HHWCF) E-list by clicking here.


  • In response to request from the HHWCF workgroup about hazardous waste characterization for LED lighting Products, DTSC is sharing the Part 3: LED Environmental Testing of the Life-Cycle Assessment of Energy and Environmental Impacts of LED Lighting Products, prepared by the U.S. Department of Energy.
  • DTSC shares the following RCRA Online Letter #1486 which addresses the topics of small containers and closed containers. To read the letter in its full entirety, please click here. Summaries of the topics are presented below:
  • Small containers (e.g. vials or tubes) of hazardous waste that are too small to label with the words "hazardous waste" are to be placed in a properly labeled larger container which would have the added benefit of secondary containment should the small container break.
  • A container holding hazardous waste must always be closed during storage except when it is necessary to add or remove waste. (40 CFR 265.173(a))
