                   Subpart 67.01_General Requirements

 

Sec. 67.01-15  Classification of structures.



    (a) When will structures be assigned to a Class? The District 

Commander will assign structures to Class A, B, or C as part of 

processing an application for a permit to establish and operate lights 

and sound signals.

    (b) In general, where will the different classes of structures be 

located? Specific criteria in paragraph (c) of this section may create 

exceptions, but, in general, structures the farthest from shore are 

likely to be assigned to Class A and required to have obstruction lights 

and sound signals that can be detected from the farthest distance. 

Structures closest to shore are likely to be assigned to Class C and, 

while subject to requirements to ensure that they are also detectable 

from a safe distance away, will be required to have the least powerful 

obstruction lights or sound signals. The location and standards for 

Class B structures will generally be in between Class A and C 

structures.

    (c) What criteria will be used to classify structures? When 

assigning a structure to a class, the District Commander will take into 

consideration whether a line of demarcation has been prescribed, and 

matters concerning, but not necessarily limited to, the dimensions of 

the structure and the depth of water in which it is located, the 

proximity of the structure to vessel routes, the nature and amount of 

vessel traffic, and the effect of background lighting.

    (1) If a line of demarcation has been prescribed, the District 

Commander will assign those structures seaward of the line of 

demarcation to Class A. He or she will assign all structures shoreward 

of the line of demarcation to either Class B or Class C, unless the 

District Commander determines under Sec. 67.05-25 that the structure 

should be assigned to Class A because of the structure's proximity to a 

navigable channel, fairway or line of demarcation.

    (2) If a line of demarcation has not been prescribed, the District 

Commander will assign a structure to Class A, B, or C as he or she deems 

appropriate.
