Addressing Abandoned and Leaking Underground
“Addressing Abandoned and Leaking Underground Storage Tank Sites on the Navajo Nation” Henry Haven, Geologist Leaking UST Program Navajo EPA Cross Canyon TP, Arizona I am Hona’gha’ahnii (One that walks around you-mother’s side) Born for To’dich’i’i’nii (Bitter Water - father’s side) Ta’chii’nii (Red Water - materal grandfather) Ma’ii Deeshgiizhnii (Coyote Pass - Paternal side Nali) Navajo Nation Underground Storage Tank and Leaking Underground Storage Tank Program P.O. Box 339 Window Rock, Arizona Phone No. (928) 871-7993 Stephen Etsitty, Executive Director, Navajo Nation Environmental Protection Agency Arlene Luther, Director Waste Regulatory Compliance Henry Haven, Geologist, Warren Roan, ES 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! Signed the Treaty of Peace with the United States in 1868 Saved the Nation with Our Native Tongue in WW II which we were not to speak in our education Current Situation ¾ ¾ ¾ ¾ Population: 200,000 Youth comprise more than 50% of the population. Median age of overall population was only 24 years old in 2000 40% of Navajo people lack running water and electricity. 43% of Navajo people live below the poverty level in 2000 ¾ ¾ ¾ Lack of economic development. Navajo Unemployment rate 52.19% in 2001 The worst unemployment rate in the US was 7.4% 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 U.S.EPA and NNEPA UST Joint Compliance Inspection at Tuba City, Arizona Bo Boquillus Canoncito Questionable abandoned tanks sites Navajo UST Tank Removal 2004 Navajo Nation Impacted Soil & Groundwater Abandoned Tank sites Ramah Alamo Navajo Nation UST/Leaking UST Sites 9/21/04 Hhaven NEP A 652 700 Num ber of S ites 600 500 400 300 200 142 86 63 42 100 0 Working Working 142 Working Sites Abandoned, Tanks Present Abandoned, Tanks Present 86 abandoned sites tanks present Tanks Questionable Leaking UST Tanks Questionable 42 abandoned sites tanks questionable Approx Total Tanks Leaking UST Approx Total Tanks 63 Leaking UST sites Navajo Nation UST/Leaking UST Sites 9/21/04H haven N EP A 19% 42% 13% 26% Working Abandoned, Tanks Present Tanks Questionable Leaking UST Over 50% of the UST sites pose a risk to surface and groundwater resources.

Former Davis Chevrolet Leaking UST site Tuba City, Arizona Burnham Mine Diesel contamination of Groundwater at 20 feet Heavy Petroleum Contaminated Soil in tank pits Shiprock, NM 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 Site Assessment •Program Field data gathering Location How many tanks Water wells -Tasks by Contractors notification, archaeological and utility clearances, Site Safety plans, PCS removal, sampling, bio-treat, tank destruction, Schedule Tank Removals, and Final Reports •Phase II Drilling and monitoring well completion •Remediation Pine Springs Trading Post, Pine Springs, Arizona Remedial Activities Removing abandoned tanks J.V.
