Department Secretary Ryan Zinke will recommend to make no changes, shrink, or eliminate the monument status entirely for the Carrizo along with 20 other monuments by Thursday.
The Carrizo Plain in Eastern San Luis Obispo County was one of 27 national monuments in the Western US which Zinke was ordered to review by an executive order from President Trump in April.
Late last week, over 130 businesses throughout San Luis Obispo, Santa Barbara, Kern and Ventura Counties collectively sent a letter to Zinke, urging him to keep all protections to the land in place.
"Our companies are diverse, ranging from farms and ranches to retail shops, hotels and restaurants, wineries and breweries, technology companies, service industries, and outdoor recreation and tourism destinations," the letter said. "Protected open spaces like the Carrizo Plain National Monument provide a boon to our local economies."
So far, Zinke has announced no changes to six national monuments, including the Sand to Snow National Monument near Los Angeles.
