I want to introduce the Navajo people, their traditional
beliefs on the environment, report on the UST and
LUST programs on the Navajo Nation, and end with
Issues and Concerns
San Juan River Bluff, Utah
We were given the name “Navajo” by the Spaniards,
but we call ourselves “Diné.” Diné means “The
People”
Window Rock
Navajo traditions and cultural values
Window Rock, Navajo Nation
Our lands – Nihi keyah
(under our feet)
According to our history,the Holy people, we were placed
in the midst of the four sacred Mountains. We were
given ceremonies to keep healthy, maintain balance
with the living world and prosper. The sacred
Mountains are alive and our guardians.
Tsisnajini – Blanco Peak
Tsoodzil- Mount Taylor
Dook’o’osliid –San Francisco Peak
Dibe Ntsaa – Mount Hesperus
San Francisco Peaks
Flagstaff, AZ.
Water – To’
All healing ceremonies use water.
Waste or disrespect of water is
discouraged.
Water is one of the most important
element for growth and nourishment of
all living things.
Springs & other sources of water are
sacred.
Monument Valley, Utah
Air - Nilchi
Air, like water, is another sacred element.
Air sustains all living things, too.
Sunshine is required for growth of the plants, the animals, and people.
Four Corners Powerplant,
Fruitland, NM
Fire – Ko’
Fire, like water and
air, is another
sacred element.
Forest fires rejuvenates the forest
The sun, a blazing ball of fire, provides sunshine, which is required for
growth of the plants, the animals, and people.
Goosenecks, Utah
These elements that we hold sacred, the
earth, air, water, and fire from which we
think all substances are derived from,
appears to be a ludicrous theory to
others. Before we are too critical of our
grandfathers, their beliefs are not silly.
If you take earth, air, and water to mean
solids, gases, and liquids, then any object
can be said to composed of a
combination of those materials.
Navajo Traditions & Culture
Everyone should take care of Mother Earth
and her water resources.
Tuba City, AZ
Navajo Traditions & Culture
Know K’e. K’e is how to live in balance with nature
and all of Mother Earth’s inhabitants and surroundings.
Mexican Hat, Utah
We survived the Walk of Torture
when we were removed from our
homelands!

United States in 1868

Our Native Tongue in WW II

Creation of the Navajo UST
and LUST Program
Cleanup Standards should incorporate
the value of ‘sacredness’ for land, water and air.
NAPI Farmington, NM
Navajo Nation UST ACT 1998
The Navajo Nation Council
declared that groundwater
can become contaminated
from releases of petroleum
from underground storage
tanks.
NN UST ACT was passed by
the Navajo Nation Council
on October 29, 1998.
The NN UST ACT Section
703 established a Leaking
UST Fund for use for
corrective actions, removal
of abandoned tanks, and
cleanup of sites.
Navajo Nation President Joe Shirley signed $1.3 Million Dollar
contracts on January 23, 2004 to address removal of abandoned
USTs and clean up of contaminated shallow groundwater.
Navajo UST/LUST Program
Federal Funds from USEPA
-$125,000 UST Grant
-$200,000 LUST Grant
Under this grant we were trained by USEPA to do UST
compliance Inspections and now lead inspections at
approximately 142 sites throughout the Navajo Nation.
Under the LUST grant we monitor approximately 61 sites for
groundwater sampling activities, drilling groundwater
monitoring wells, and cleanup methods and activities

Guidelines for use of the Navajo Nation LUST TRUST Fund
Assessment Strategy for abandoned sites
1. Human Health- inform family of abandoned UST and advise them not
park on top of tanks or remove the tanks themselves
2. Depth to Groundwater- determine wells within 3 mile radius and
determine depths and use of water wells
Canoncito TP, Canoncito, NM
3. Age of Tanks- sites with USTs
before 1980 will be assess for
lead. Soil samples will be obtain
beneath tanks and analyzed for
BTEX and Lead
Tanks become pitted and
corroded over time
Holes are 1/2 to 1 inch
in size
Tanks closed in place Fort
Defiance, AZ
4.
Other Potential Exposuregeophysical survey,
electromagnetic survey for
USTs, determine if gasoline
is still in tanks, PID is used
to determine explosive
limits (<10% oxygen and
<10% LEL)
5. Assistance to Achieve Compliance- Where Financial
resources have been exhausted the program will assist
with removal and disposal of PCS, removal of UST,
and assist in drilling and completing MWs

cream cone ingredient, fire extinguishers), dipotassium Phosphate (coffee
Creamer- act as surfactant or soap to wash petroleum out), and Dextrose Solution
(powder sugar) to feed the microorganisms.

UST
LUST
Under the grants we do UST compliance Inspections at approximately 142 sites
throughout the Navajo Nation.
Under the LUST grant we monitor approximately 61 sites for groundwater sampling
activities, drilling groundwater monitoring wells, and cleanup methods and activities
(i.e. Tuba City Leaking UST site, St. Michaels Chevron site).

Issues
Shallow Groundwater Contamination
Steel Underground storage tanks
Lack of Aggressive Clean up and Enforcement
Natural Attenuation is not an aggressive clean up method
No corrective action for 15-20 years
Lack of Personnel to conduct UST inspections, follow up,
corrective action Multi-task for few personnel
Recommendations
Upgrade tanks to fiberglass, double wall tanks
Do annual tank tightness test and lines
Watch tank gasoline deliveries
Be Aware of USEPA Funding Awards!
Any Questions? Thanks.
