The tribe says the construction threatens to destroy historicalareas and ancient burial sites. They also say the pipeline could pollute their mainwater source, the Missouri River. In April, the Standing Rock Sioux began a protestagainst the project. They camped at the construction site. Since then, thousands ofpeople, including people from other American Indian tribes, have traveled to the siteto join the protest.

ETP says that the pipeline will have built-in safety measures to protectagainst oil leaks. Workers will also monitor it remotely, and will be able to closevalves (阀) within three minutes if leaks are detected.

American Indians have been staging a nonviolent protest for months. Theprotest took a turn last week when police were called to keep the peace betweenprotesters and armed security guards hired by the company.
