H.R. 4290 would direct the Department of the Interior to install a historical marker in White Sands National Park in New Mexico to commemorate the effects of radiation on people in New Mexico resulting from the nuclear test conducted on July 16, 1945, at the Trinity Site at the White Sands Proving Ground in Socorro County, New Mexico.

Using information about the costs of similar requirements, CBO estimates that implementing H.R. 4290 would cost less than $500,000 over the 2026-2031 period. Any related spending would be subject to the availability of appropriated funds.

The CBO staff contact for this estimate is David Rafferty. The estimate was reviewed by H. Samuel Papenfuss, Deputy Director of Budget Analysis.
