S. 521 would direct the Secretary of the Interior to study the suitability and feasibility of designating the President Street Station in Baltimore, Maryland, as a unit of the National Park System (NPS). Based on information from NPS, CBO estimates that carrying out the proposed study would cost about $200,000; such spending would be subject to the availability of appropriated funds. Enacting S. 521 would not affect direct spending or revenues; therefore, pay-as-you-go procedures do not apply.
S. 521 contains no intergovernmental or private-sector mandates as defined in the Unfunded Mandates Reform Act and would affect the budgets of state, local, or tribal governments.
