To achieve this goal, the program oversees environmental site assessments, approves corrective action plans, and oversees the actions conducted pursuant to those plans.

underground injection by petroleum companies operating on the Navajo Nation. Brine solutions used to recover oil and gas are buried deep within the ground, as allowed by a permitted Class II injection well. These wells are drilled through geologic layers and through drinking water sources. The cement casing used in developing a Class II injection well is required to protect underground sources of drinking water (USDWs). These Class II underground injection wells are primarily located in the northern part of the Navajo Nation, in the Shiprock Agency and the Eastern Agency. https://navajoepa.org/public-water-systems-supervision-program daily 0.75 2026-02-13 https://images.squarespace-cdn.com/content/v1/61f18d0ee0605f4e06b817ca/e1382ac6-7d1f-4696-ad08-86b44b185bfb/Low+Mountain+BIE+BIA+School+2010.jpg https://images.squarespace-cdn.com/content/v1/61f18d0ee0605f4e06b817ca/1745002648303-WQU6RADGOFF5CJDN4LDZ/unsplash-image-vkgzPtlIgbU.jpg https://images.squarespace-cdn.com/content/v1/61f18d0ee0605f4e06b817ca/1745002579838-WE8KZGT20UHRFQ4PQRRZ/unsplash-image-3leBubkp5hk.jpg https://images.squarespace-cdn.com/content/v1/61f18d0ee0605f4e06b817ca/1745002745188-0OWNQQA10IJRY33F0FWO/unsplash-image-PDRFeeDniCk.jpg https://images.squarespace-cdn.com/content/v1/61f18d0ee0605f4e06b817ca/1745010960791-BHU5GEK0JDZPJMTW8X91/unsplash-image-o2I4HsudmlY.jpg https://navajoepa.org/about-the-department-2 daily 0.75 2023-03-31 https://images.squarespace-cdn.com/content/v1/61f18d0ee0605f4e06b817ca/1666882805591-I1UJKS3HRAC8XALIJ5LS/unsplash-image-LoGnr-w1D8E.jpg https://navajoepa.org/water-qualitynnpdes-program daily 0.75 2025-03-26 https://navajoepa.org/septic-tank-reporting-form daily 0.75 2023-01-13 https://navajoepa.org/water-statutes-regulations-and-forms daily 0.75 2025-04-18 https://navajoepa.org/crossconnection-control-program daily 0.75 2025-12-05 https://images.squarespace-cdn.com/content/v1/61f18d0ee0605f4e06b817ca/78676247-1860-485b-91e1-65350070cbf1/Low+Mountain+BIE+BIA+School+2010.jpg Cross-Connection Control Program -
