Enviros sue Zinke in bid to halt 100+ O&G lease planned near Dinosaur NMon

DENVER (CN) — Four environmental groups sued Interior Secretary Ryan Zinke on Thursday to protect the two-state Dinosaur National Monument from increased air pollution from oil and gas drilling.

Established in 1915, the Dinosaur National Monument encompasses 200,000 acres from Rio Blanco County in northwest Colorado to northeast Utah counties Duchesne and Uintah. An estimated 300,000 people a year visit the park’s 1,500 fossils exposed on the cliff face inside the Quarry Exhibit Hall, spending around $18 million in local economies.
