1. What is accepted at the Hazardous Products Center (HPC)?

Please view a list of accepted waste on the following web page:

HPC Accepted Waste

2. Why is the Flagstaff Hazardous Products Center (HPC) at the Cinder Lake Landfill?

The HPC is able to divert Hazardous Waste and Electronic Waste from entering the Cinder Lake Landfill. Because of this, the Landfills life expectancy is expanded and we keep any hazardous materials out of the environment. The location is also the most cost effective use of tax payers money.

3. Is there another place in town that will accept my hazardous waste?

Yes, however accepted hazardous waste items in town are limited. 

Compact Fluorescent Lamps (CFL's) can be dropped off at either Home Depot Location, The Lite Company (on Fourth Street) or the HomeCo Ace Home Center on Butler. 

Electronics may be accepted at Staples (928) 214-8424 and Best Buy (928) 522-6141. Please call in advance for more information. 

Old Fire extinguishers can be taken to Personnel Zee Safety. Call (928) 526-3130 for more information/directions. 

BBQ Propane cylinders are accepted at Graves Propane. Call (928) 714-1111 for more information.

4. How do I properly package and transport waste to the HPC?

Use original containers and labels whenever possible to decrease the risks of spills and exposure. If the container is compromised in any way, use a secondary container to contain the spill. In addition, bring a copy of any SDS’s that pertain to your particular waste. This will cut down the amount of time needed to investigate your hazardous materials.

Be aware of leaking chemicals, as they can react while in transport and pose a serious risk to you, your occupants, and the general public. Keep your vehicle well ventilated and drive with care.

5. When is the HPC open to residents?

The HPC is open Mondays through Saturdays from 8:00 a.m. to 3:00 p.m. We are also open on most major holidays with the exception of Thanksgiving, Christmas, and New Year's Day.

6. I have a business; can I bring my hazardous waste to the HPC?

Yes, but you must qualify as a Very Small Quantity Generator (VSQG) and it is by appointment only. 

You can contact the HPC at (928) 213-2159 or send an email to hpc@flagstaffaz.gov. HPC staff will be able to help determine if you qualify for our Small Business Waste Program and can help you find the best way to dispose of your hazardous waste.

7. I have old gasoline and/or diesel fuel which I need to dispose of and I want my container back...?

The HPC is closed
