Q&A: PCBs and DEHP in Lighting Ballast

Q&A:  PCBs and DEHP in Lighting Ballast

Q&A: PCBs and DEHP in Lighting Ballast

On February 12, 2015 a person who I assume to be a demolition contractor – not a customer of mine – asked a question through the Contact Me page of my website.

light fixture ballastI am working on a demolition project removing a coal fed power plant. The demolition crew is in the process of removing universal waste and as they remove the light ballasts we are checking for PCB/No PCB’s to determine how to dispose of them. Now reading further into the disposal process I came across DEHP. I did a little research on this DEHP and on your website it says that DEHP is a hazardous waste if it’s pure, but once used in a ballast it will no longer meet the description of a U-listed hazardous waste. My interpretation of that is it is no longer a hazardous waste and can be disposed of as construction debris as long as is not exhibiting leakage. Please respond. Thank You.

Thank you for contacting me with your question.  I apologize for taking so long in getting back to you.

I assume you read my blog article on the disposal of lighting ballast.  I’m glad you were able to use it as guidance.  In sum:

  • The generator of a waste is required to make the hazardous waste determination based on generator knowledge (e.g. “No PCB” written on a ballast and/or its date of manufacture) or analytical (e.g. collecting a sample and submitting it to a lab for analysis).
  • Unless disposed of unused, DEHP is not a listed hazardous waste.
  • A ballast may be a hazardous waste if it exhibits a characteristic (i.e. Ignitability, Corrosivity, Reactivity, Toxcity).  While I don’t think a ballast will exhibit any of these hazardous waste characteristics, it is possible and it is the generator’s responsibility to make this determination.
  • If the ballast does not contain PCBs, is used and therefore not a U-Listed hazardous waste, and does not exhibit a characteristic, then it is not a hazardous waste and can be disposed of in non-hazardous (Subtitle D) landfill.  Whether it is leaking or not should not be an issue.
  • Free liquids cannot go to landfill.
  • The landfill may not wish to accept this waste – or any other – at its own discretion.
  • I am not familiar with construction debris landfills to speak to that issue.
  • Recycling as scrap metal (if approved by the recycler) is preferable to landfill disposal (in my opinion).

I hope this helps.

Thank You for your reply.

Got a question?  Whether your a customer of mine or not I’m glad to help in any way I can.
