Mare Island Drydocks Reuse Project [California Endangered Species Act (CESA) Incidental Take Permit No. 2081-2010-009-07 Major Amendment 7 (ITP)]

The Mare Island Dry Docks Incidental Take Permit (ITP) previously issued involves the establishment and operation of a ship repair/dismantling facility. Activities associated with this project include the rehabilitation and dredging of existing Drydocks 2 and 3 and Berths 11-14. CDFW issued the existing ITP to address and authorize, as fully mitigated, related impacts to Delta smelt (Hypomesus transpacificus), longfin smelt (Spirinchus thaleichthys), winter-run Chinook salmon (Oncorhynchus tshawytscha), and spring-run Chinook salmon, species designated as endangered or threatened under CESA. Major Amendment No. 7, as approved, modifies the previously issued ITP, to extend the expiration date to April 30, 2021, and extend the documentation of the final mitigation report date to June 15, 2021. This amendment also includes the use of Dry Dock 1 for normal docking and repair operations, modifies the dredging depths in front of Dry Docks 1-4 and Berths 11-16, modifies the dredging work window, reduces the total number of evolutions allowed under this ITP from 416 to 230, and adds condition of approval 6.9, which requires salinity testing for all dredge events that occur between December 1 and July 31. In approving Major Amendment No. 7, CDFW determined, among other things, that no substantial increase in the nature or scope of the previous authorization provided by the CESA ITP, and that no new significant or substantially more severe environmental impacts than previously considered and disclosed would occur.
