미국 환경보호청(EPA)과 나바호 환경보호청(Navajo Nation EPA, NNEPA)은 나바호 인디언 보호구 공공재 공단(Navajo Tribal Utility Authority, NTUA)과 연방 수질오염방지법, 나바호 수질오염방지법에 준수해 Window Rock지역의 폐수처리 시설 관련 협약을 체결했다고 발표했다.

EPA의 이번 계약으로 NTUA가 요구한 2만5천 달러의 벌금이 지불되었고, NNEPA가 제시한 획기적인 합의 방안이 지지되었다. 기업이 나바호 수질오염방지법에 근거해 위반에 대한 벌금을 지불한 것은 이번이 처음이다.

The Environmental Protection Agency (EPA) and the Navajo Nation EPA (NNEPA) have announced a pair of settlements with the Navajo Tribal Utility Authority (NTUA) to bring its wastewater treatment facility in the city of Window Rock into compliance with both the federal Clean Water Act and the Navajo Nation Clean Water Act.

EPA's agreement backs up a recent ground-breaking NNEPA settlement that required the NTUA to pay a $25,000 penalty. This is the first time that a tribally-owned entity has paid a penalty for violations of the Navajo Nation Clean Water Act. The NTUA has committed to bring the Window Rock facility into full compliance by December 31, 2015, or face additional penalties. NTUA has also agreed to build new infrastructure for the treatment plant at the site.

An EPA inspection revealed that since at least 2011, NTUA had been discharging pollutants above its permit limits to Black Creek, a tributary of the Puerco River that feeds into the Little Colorado River. Other violations of the NTUA's National Pollutant Discharge Elimination System permit included its failure to submit complete and timely reports while inadequately operating and maintaining its existing treatment system. The plant collects and treats sanitary sewage from a population of about 13,300 in Apache County, Ariz., within the boundaries of the Navajo Nation.

The settlements require the NTUA to conduct sampling, submit quarterly reports, train and certify the plant's operators, and hold regular compliance meetings with senior officials of EPA and NNEPA. The NTUA will also submit a plan for EPA and NNEPA's approval for the construction of an entirely new treatment plant including a detailed schedule for commissioning and bringing the new facility online. Approximately $10 million in funding for the new facility was provided through the U.S. Department of Agriculture's Rural Utilities Service Water and Waste Disposal Loans and Grants Program.
