Procedures for hydroacoustic monitoring shall be consistent with the California Department of Transportation 2020 Technical Guidance for the Assessment of Hydroacoustic Effects of Pile Driving on Fish.

Restricting impact pile driving activities to specific times of the day and for a specific duration to be determined through coordination with CDFW, NMFS, and USFWS and subject to CDFW approval.

Permittee shall not exceed the limits on pile driving identified in Tables 4 - 6 below and as approved by CDFW in the pile driving plan (Condition of Approval 11.34).

Additionally, pile driving shall not occur before 7:00 a.m. or after 7:00 p.m.

Equipment to minimize underwater noise generated by impact pile driving shall include using vibratory rather than impact pile driving equipment where feasible; noise attenuation with pile caps (e.g., wood or micarta), bubble curtains, air-filled fabric barriers, or isolation piles; or installation of piling-specific cofferdams.

Initiating impact pile driving with a “soft-start” where feasible, such that pile strikes are initiated at reduced impact and increase to full impact over several strikes to provide fish an opportunity to move out of the area.

Permittee may conduct in-water impact pile driving (i.e., outside of a cofferdam or sheet pile walls) at the north Delta intakes from May 16 – May 31 and November 1 – November 15 if bubble curtains or other measures for noise attenuation demonstrate that an equivalent level of protection can be achieved as during the June 1 – October 31 work window and real-time monitoring of Covered Species demonstrates absence in the work area, and as approved in writing by CDFW.

In-channel acoustic monitoring is required to verify that generated sound thresholds do not exceed the disturbance threshold of 150 dB at 10 meters from source.

Disturbance threshold for fish of all sizes is 150 dB root mean square relative to 1 micropascal.

Injury threshold for fish of all sizes includes a peak sound pressure level (SPL) of 206 dB relative to 1 micropascal; • Injury threshold for fish less than 2 grams is 183 dB relative to 1 micropascal cumulative sound exposure level (SELcumulative); and • Injury threshold for fish greater than or equal to 2 grams is 187 dB relative to 1 micropascal SELcumulative.
