They argued the program helps localities offset losses from non-taxable federal lands. Enzi and Udall said without that funding, counties would experience economic hardship. 

“Property taxes fund county governments allowing them to provide essential services such as law enforcement, public safety, infrastructure maintenance, education, and health services for local communities. A fully funded PILT program helps to offset the loss of these important revenues and fulfill the federal governments’ obligation to local communities with large amounts of federal land,” the senators wrote in a letter Monday to committee Chairwoman Barbara MikulskiBarbara MikulskiClinton: White House slow-walking Russia sanctions Top Lobbyists 2017: Hired Guns Gore wishes Mikulski a happy birthday at 'Inconvenient Sequel' premiere MORE (D-Md.) and ranking member Richard ShelbyRichard Craig ShelbySenators push mandatory sexual harassment training for members, staff Justice Dept drops case against woman who laughed at Sessions Former Hill staff calls for mandatory harassment training MORE (R-Ala.).

Mikulski and Shelby are working on an omnibus spending bill that Congress needs to pass by mid-January to avert another government shutdown.

“We urge you to consider the economic hardship and uncertainty that counties across the nation will face if the PILT program is not given consistent funding,” the letter stated. “We understand the Appropriations Committee has some tough funding decisions in the coming weeks and we appreciate your consideration of this important issue.”

Annual PILT payments are computed by the Department of the Interior based on the number of acres of federal entitlement land within each county or jurisdiction and the population. The lands include the National Forest and National Park Systems, the areas managed by the Bureau of Land Management, those affected by the U.S. Army Corps of Engineers and Bureau of Reclamation water resource development projects.
