This legislative proposal, designated as the "Hudson River Protection Act," aims to modify the William M. (Mac) Thornberry National Defense Authorization Act for Fiscal Year 2021. Its primary objective is to introduce new restrictions on vessel activities within a designated section of the Hudson River. Specifically, the bill directs the Commandant to prohibit any vessel from anchoring in the specified reach of the Hudson River. This prohibition includes an important exception, allowing anchoring only in those anchorage grounds that were established prior to January 1, 2021 , thereby limiting new or expanded anchoring activities.
