Corrections

On page 51118, table 7 is corrected to read as follows:

Table 7—SSLs for Project Activities

Sound source SSL
SEL SPL RMS
3 tugs at 50 percent power 185 dB at 1 m.
4 tugs at 50 percent power 186.2 dB at 1 m.
Conductor pipe pile (20 in, impact) 184 dB at 10 m 193 dB at 10 m.

On page 51120, table 10 is corrected to read as follows:

Table 10—Level A Harassment and Level B Harassment Isopleths From Tugging and Impact Pile Driving

Sound source Level A Harassment Isopleths (m) Level B Harassment Isopleths (m)
LF MF HF PW OW
Conductor pipe pile, 70 percent installation 3,064 109 3,650 1,640 119 1,585
Conductor pipe pile, 30 percent installation 1,742 62 2,075 932 68
Tugging/Positioning, 3 Tugs 95 78 679 69 0 3,850
Tugging/Positioning, 4 Tugs 108 89 773 79 1 4,483
These zones are results from Hilcorp's modeling.
For otariids, Hilcorp's model estimated a Level A harassment zone of 0 during tugging/positioning with three tugs. Therefore, for four tugs, NMFS applied the Level A harassment zone calculating with the User Spreadsheet.
