Enclosure 2 to COMDTINST 16478.12
The general characteristics of the "typical" AtoN in each priority summarized
in Table III below. Of course, this is intended as a general guide for
comparison purposes only.Individual aids in each category may have different
characteristics, but their sum ranking scores should be comparable.
5.0 Rankings by Coast Guard District
The results of the priority ranking model are summarized in Table IV (Summary
of Priority Rankings by Coast Guard District) and Table V (Summary of Priority
Rankings by State). The distribution and ranking of AtoNs are displayed
graphically in Appendix I (Priority Ranking Maps). Over 70% of the 12,075
sites ranked fell into the two lowest priority categories. The majority of
lower priority sites are located in offshore and coastal areas or on major
rivers, away from dense population areas. The 13% of AtoN in the two highest
priority categories are generally located near inland population concentrations
on navigable freshwater lakes and rivers, reflecting the concern that these
could be potential drinking water supplies, or have sediment characteristics
that make them a high priority for consideration.
