COMPTUEX/JTFEX EA/OEA Final Chapter 4the proposed action would not affect annual rates of recruitment or survival for false killer whales, andwould not have a significant impact on this species and stock.Harbor Porpoise (Phocoena phocoena)Harbor porpoises are rarely within the northern range areas and therefore were not included in the marinemammal acoustic effects analysis.Killer Whale Offshore and Resident Stock (Orcinus orca)The abundance estimate of killer whales is 1,340 (CV = 0.31), using the offshore water habitat. Themodeling efforts and harassment analysis for mid-frequency active sonar estimate that no Level Aharassment of killer whales would occur. The analysis estimates that up to 12 incidents of non-injuriousbehavioral harassment and 1 incident of non-injurious physiological harassment (Level B harassment)may be experienced by killer whales on annual basis (Table 4.3-19). No killer whales would be exposedto impulsive noises or pressures from underwater detonations that would cause TTS or physical injury.Table 4.3-19.
