# SUPPLEMENTARY INFORMATION:

## Background 

                    The tidewater goby is a small, grayish brown fish approximately 2 inches long and which lives for about one year. It occurs in coastal brackish-water habitats such as lagoons, tidal bays, and estuaries of rivers and streams along the California coastline. This fish is threatened by habitat loss and degradation, predation by non-native species, and extreme weather and streamflow conditions. On August 3, 1999, the Fish and Wildlife Service published a rule proposing critical habitat for the tidewater goby                     *Eucyclogobius newberryi*                     in the                     **Federal Register**                     (64 FR 42250), a species Federally listed as endangered throughout its range. We proposed designation of approximately 11.8 miles of rivers, streams, and estuaries as critical habitat for the tidewater goby pursuant to the Endangered Species Act of 1973, as amended (Act). Proposed critical habitat is in Orange and San Diego counties, California, as described in the proposed rule.                 

                    Section 4(b)(2) of the Act requires that the Secretary shall designate or revise critical habitat based upon the best scientific data available and after taking into consideration the economic impact of specifying any particular area as critical habitat. Based upon the previously published proposal to designate critical habitat for the tidewater goby and comments received during previous comment periods, we have conducted a draft economic analysis of the proposed critical habitat designation. The draft economic analysis is available at the above Internet and mailing address. In order to accept the best and most current scientific data regarding the critical habitat proposal and the draft economic analysis of the proposal, we reopen the comment period at this time. We will accept written comments during this reopened comment period. Previously submitted oral or written comments on this critical habitat proposal need not be resubmitted. The current comment period on this proposal closes on July 28, 2000. Written comments may be submitted to the Service office in the                     **ADDRESSES**                     section.

      ( print page 39851)    Authority:                             The authority for this action is the Endangered Species Act of 1973 (16 U.S.C. 1531*et seq.*).
