(a) Regulations in this subpart apply only to the U.S. Navy for the taking of marine mammals that occur in the area outlined in paragraph (b) of this section and that occur incidental to the activities described in paragraph (c) of this section.
(b) These regulations apply only to the taking of marine mammals by the Navy that occurs within the Keyport Range Complex Action Area, which includes the extended Keyport Range Site, the extended Dabob Bay Range Complex (DBRC) Site, and the extended Quinault Underwater Tracking Range (QUTR) Site, as presented in the Navy's LOA application. The NAVSEA NUWC Keyport Range Complex is divided into open ocean/offshore areas and in-shore areas:
(1) Open Ocean Area--air, surface, and subsurface areas of the NAVSEA NUWC Keyport Range Complex Extension that lie outside of 12 nautical miles (nm) from land.
(2) Offshore Area--air, surface, and subsurface ocean areas within 12 nm of the Pacific Coast.
(3) In-shore--air, surface, and subsurface areas within the Puget Sound, Port Orchard Reach, Hood Canal, and Dabob Bay.
(c) These regulations apply only to the taking of marine mammals by the Navy if it occurs incidental to the following activities, or similar activities, and sources, or similar sources (estimate amounts of use below):
(1) Range Activities Using Active Acoustic Devices:
(i) General range tracking: Narrow frequency output between 10 to 100 kHz with source levels (SL) between 195-203 dB re 1 microPa @ 1 m--up to 504.5 hours per year.
(ii) UUV Payloads: Operating frequency of 10 to 100 kHz with SLs less than 195 dB re 1 microPa @ 1 m at all range sites--up to 166 hours per year.
(iii) Torpedo Sonars: Operating frequency from 10 to 100 kHz with SL under 233 dB re 1 microPa @ 1 m--up to 21 hours per year.
(iv) Range Targets and Special Test Systems: 5 to 100 kHz frequency range with a SL less than 195 dB re 1 microPa @ 1 m at the Keyport Range Site and SL less than 238 dB re microPa @ 1 m at the DBRC and QUTR sites--up to 9 hours per year.
(v) Special Sonars (non-Navy, shore/pire static testing, diver activities) and Fleet Aircraft (active sonobuoys and dipping sonars): Frequencies vary from 100 to 2,500 kHz with SL less than 235 dB re 1 microPa @ 1 m--up to 321 hours per year.
(vi) Side Scan Sonar: Multiple frequencies typically at 100 to 700 kHz with SLs less than 235 dB re 1 microPa @ 1 m--up to 166 hours per year.
(vii) Other Acoustic Sources:
(A) Acoustic Modems: Emit pulses at frequencies from 10 to 300 kHz with SLs less than 210 dB re 1 microPa @ 1 m--up to 166 hours per year.
(B) Sub-bottom Profilers: Operate at 2 to 7 kHz at SLs less than 210 dB re 1 microPa @ 1 m, and 35 to 45 kHz at SLs less than 220 dB re 1 microPa @ 1 m--up to 192 hours per year.
(C) Target simulator (surface vessels, submarines, torpedoes, and UUV engine noise): Acoustic energy from engines usually from 50 Hz to 10 kHz at SLs less than 170 dB re 1 microPa @ 1 m--up to 24.5 hours per year.
(2) Increased Tempo and Activities due to Range Extension: Estimates of annual range activities and operations are listed in the following table, but may vary provided that the variation does not result in exceeding the amount of take indicated in Sec. 218.171(c): ----------------------------------------------------------------------------------------------------------------

(d) Amended regulations are effective February 1, 2012, through April 11, 2016.
(e) The taking of marine mammals may be authorized in an LOA for the activities and sources listed in Sec. 218.170(c) should the amounts (e.g., hours, number of exercises) vary from those estimated in Sec. 218.170(c), provided that the variation does not result in exceeding the amount of take indicated in Sec. 218.171(c).
