A newly opened “temporary” facility to house unaccompanied migrant children could cost up to $300 million and stay open through January 2020, the Trump administration says.

The Carrizo Springs facility in Texas officially opened June 30, and currently houses about 225 children. It is eventually expected to hold up to 1,300, which would make it one of the largest facilities for unaccompanied minors in the country, according to the Department of Health and Human Services (HHS).

The Carrizo facility is run by the non-profit firm BCFS, which HHS will pay $50 million for its first 60 days of operation, according to recent federal filings. Supplemental funding of up to $250 million will be paid if the facility is open through Jan. 31, 2020.
