Nationwide Use of High Frequency and Ultra High Frequency Active SONAR Technology; Final Programmatic Environmental Assessment and Finding of No Significant Impact
The Coast Guard (USCG) announces the availability of the Final Programmatic Environmental Assessment (PEA) for the Nationwide Use of High Frequency (HF) and Ultra High Frequency (UHF) Sound Navigation and Ranging (SONAR) Technology and Finding of No Significant Impact (FONSI). The USCG is proposing the nationwide use of active SONAR technologies that operate at frequencies of 50 kiloHertz (kHz) and greater from fixed and mobile platforms. Active SONAR technology would be used in support of USCG missions to locate, image, and classify submerged/underwater targets of interest (TOI). The PEA is a program- level document that will provide the USCG with management-level analysis of the potential impacts of each alternative on the human and natural environments.
