FAQs
What does PDEQ do?
Pima County Department of Environmental Quality
(PDEQ) is a regulatory agency whose job is to enforce state
and federal laws regarding Pima County's water, waste and air quality. In addition, PDEQ operates and maintains Pima County's solid waste landfills and transfer stations. PDEQ
increases public awareness of environmental issues through
its public education and outreach programs.
What is the difference between PDEQ and the EPA?
Pima County Department of Environmental Quality
(PDEQ) administers state laws and regulations. The U.S. Environmental
Protection Agency (EPA) administers federal laws and regulations,
but delegates much of its enforcement authority in Arizona
to PDEQ and Arizona Department or Environmental Quality (ADEQ).
How does PDEQ work with business and
industry?

Air Quality
What is the largest contributor to air pollution?
Approximately 60% of Pima County's air pollution is
caused by motor vehicle usage.
How can I improve the air quality in
my community?
There are many ways to improve air quality. Instead
of driving alone, try carpooling, walking, riding your bike
and taking the bus. See 26
Ways to Healthy Air for more tips.
How do I manage asbestos in my house
or apartment building?
Even if asbestos is in your home, this is usually
NOT a serious problem. The mere presence of asbestos in a home
or a building is not hazardous. The danger is that asbestos
materials may become damaged over time. Damaged asbestos may
release asbestos fibers and become a health hazard.
THE BEST THING TO DO WITH
ASBESTOS MATERIAL IN GOOD CONDITION IS TO LEAVE IT ALONE! Disturbing
it may create a health hazard where none existed before.
Read the asbestos awareness
information before you have any
asbestos material inspected, removed, or repaired.
What can I do if my older car fails the
state emissions test?
Since the majority of our air pollution in Pima
County comes from motor vehicle use, maintenance of your vehicles
emission system is critical to improve and maintain our air
quality. If your vehicle is 12 years or older and it fails
the state emissions test, you may qualify for financial assistance
for vehicle emission repairs through the PDEQ
Voluntary Vehicle Repair and Retrofit Program.

What does Pima County DEQ do to reduce illegal dumping?
Staff investigate all complaints regarding illegal dumping (wildcat dumping). Staff performs routine surveillance of private and public lands throughout Pima County that are frequent dump sites. Staff will obtain evidence, issue citations to responsible parties, and ensure proper disposal of the solid wastes. Once a month, staff supervises Adult Probation Workers during the cleaning of public land of "wildcat" solid waste. Staff also coordinates neighborhood clean-ups with community leaders and neighborhood groups.
How can I report illegal dumping?
• Report illegal dumps by calling 622-5800 (available 24 hours a day)
• Report illegal dumps from this site by going to the COMPLAINTS page and submitting a complaint
• NEVER approach an illegal dumper
• If you see illegal dumping activity, REPORT IT immediately - call 622-5800. (Try to get a license number, vehicle description, or other identifying information.)
What are hazardous wastes?
A waste is any solid, liquid, or contained gaseous
material that is discarded by being disposed of, burned or
incinerated, or recycled. (There are some exceptions for recycled
materials.) It can be the by-product of a manufacturing process
or simply a commercial product that you use in your business--
such as a cleaning fluid or battery acid-- that is being disposed.
Even materials that are recyclable or can be reused in some
way-- such as burning used oil for fuel-- may be considered
waste.
How do I know if waste is hazardous or
just garbage?
Read the label. In many cases, a hazardous material
will be indicated by a Caution, Warning, or Danger heading.
(For example, a pesticide might say Warning: Poison.)
How do I know if my small business is
generating hazardous waste?
A waste is hazardous if it demonstrates one or
more of the following characteristics:
• Ignitable. Ignitable wastes can create fires under certain
conditions. Examples are paints and certain degreasers and
solvents.
• Corrosive. Corrosive wastes are those that corrode metals
or have a very low pH. Examples are rust removers, acid or
alkaline cleaning fluids, and battery acid.
• Reactive. Reactive wastes are unstable under normal conditions.
They can create explosions and/or toxic fumes, gases, and vapors
when mixed with water or under other conditions, such as heat
or pressure. Examples are certain cyanides or sulfide-bearing
wastes.
• Toxic. Toxic wastes are harmful or fatal when ingested
or absorbed; or they leach toxic chemicals into the soil
or ground water when disposed of on land. Examples are wastes
that contain high concentrations of heavy metals, such as
cadmium, lead, or mercury. Additionally, a mixture of hazardous
waste with solid waste (e.g., motor oil, trash, debris) may
become a hazardous waste.
