    SUMMARY: The Fish and Wildlife Service (Service) determines endangered 
    status pursuant to the provisions of the Endangered Species Act of 
    1973, as amended (Act), for the tidewater goby (Eucyclogobius 
    newberryi). The tidewater goby is a fish that occurs in tidal streams 
    associated with coastal wetlands in California. Since 1900, the 
    tidewater goby has disappeared from nearly 50 percent of the coastal 
    lagoons within its historic range, including 74 percent of the lagoons 
    south of Morro Bay in central California. Only three populations 
    currently exist south of Ventura County. This rule implements the 
    protection and recovery provisions provided by the Act for the 
    tidewater goby.
    
    EFFECTIVE DATE: March 7, 1994.
    
    ADDRESSES: The complete file for this rule is available for inspection, 
    by appointment, during normal business hours at the Ventura Field 
    Office, U.S. Fish and Wildlife Service, 2140 Eastman Avenue, suite 100, 
    Ventura, California 93003.

    SUPPLEMENTARY INFORMATION:
    
    Background
    
        The tidewater goby (Eucyclogobius newberryi) is a small fish, 
    rarely exceeding 50 millimeters (2 inches) standard length, and is 
    characterized by large pectoral fins and a ventral sucker-like disk 
    formed by the complete fusion of the pelvic fins. The tidewater goby 
    was first described as a new species (Gobius newberryi) by Girard 
    (1856), from specimens collected in the San Francisco Bay area. Based 
    on Girard's specimens, Gill (1862) reassigned Gobius newberryi to the 
    newly described genus Eucyclogobius (Eschmeyer 1990).
        A member of the family Gobiidae, the tidewater goby is the only 
    species in the genus Eucyclogobius and is almost unique among fishes 
    along the Pacific coast of the United States in its restriction to 
    waters with low salinities in California's coastal wetlands. All life 
    stages of tidewater gobies are found at the upper end of lagoons in 
    salinities less than 10 parts per thousand (ppt); however, gobies from 
    two populations have been collected and reared in slightly higher 
    salinities (Ramona Swenson, University of California, Berkeley, in 
    litt. 1993). Although its closest relatives are marine species, the 
    tidewater goby does not have a marine life history phase. This lack of 
    a marine phase severely restricts the frequency of genetic exchange 
    between coastal lagoon populations and significantly lowers the 
    potential for natural recolonization of a locality once extirpated. 
    Studies by Crabtree (1985) noted that some populations of gobies have 
    differentiated genetically, indicating a long period of isolation. 
    Tidewater gobies have a short lifespan and seem to be an annual species 
    (Irwin and Stoltz 1984, Swift 1990), further restricting their 
    potential to recolonize habitats from which they have been extirpated.
        The tidewater goby occurs in loose aggregations of a few to several 
    hundred individuals on the substrate in shallow water less than 1 meter 
    (3 feet) deep (Swift et al. 1989), although gobies have been observed 
    at depths of 1.5 to 2.3 meters (4.9 to 7.6 feet) (Dan Holland, 
    University of Southwestern Louisiana, in litt. 1993). Peak nesting 
    activities commence in late April through early May, when male gobies 
    dig a vertical nesting burrow 10 to 20 centimeters (4 to 8 inches) deep 
    in clean, coarse sand. Suitable water temperatures for nesting are 18 
    to 22 deg.C (75.6 to 79.6 deg.F) with salinities of 5 to 10 ppt. Male 
    gobies remain in the burrows to guard eggs, which are hung from the 
    ceiling and walls of the burrow until hatching. Larval gobies are found 
    midwater around vegetation until they become benthic (Swift et al. 
    1989). Although the potential for year round spawning exists, it is 
    probably unlikely because of seasonal low temperatures and disruptions 
    of lagoons during winter storms. Ecological studies performed at two 
    sites documented spawning occurring as early as the first week in 
    January (Swenson in litt. 1993). Although usually associated with 
    lagoons, the tidewater goby has been documented in ponded freshwater 
    habitats as far as 8 kilometers (5 miles) upstream from San Antonio 
    lagoon in Santa Barbara County (Irwin and Stoltz 1984).
        The tidewater goby is discontinuously distributed throughout 
    California, ranging from Tillas Slough (mouth of the Smith River) in 
    Del Norte County south to Agua Hedionda Lagoon in San Diego County. 
    Areas of precipitous coastlines that preclude the formation of lagoons 
    at stream mouths have created three natural gaps in the distribution of 
    the goby. Gobies are apparently absent from three sections of the coast 
    between: (1) Humboldt Bay and Ten Mile River, (2) Point Arena and 
    Salmon Creek, and (3) Monterey Bay and Arroyo del Oso.
        Roughly 10 percent of the coastal lagoons presently containing 
    populations of tidewater goby are under Federal ownership. Over 40 
    percent of the remaining populations are either entirely or partly 
    owned and managed by the State of California. The remainder are 
    privately owned.
    
    Previous Federal Action
    
        The tidewater goby was first classified by the Service as a 
    category 2 species in 1982 (47 FR 58454). It was reclassified as a 
    category 1 candidate in 1991 (56 FR 58804) based on status and threat 
    information in Swift et al. (1989). Category 2 applies to taxa for 
    which information now in the possession of the Service indicates that 
    proposing to list as endangered or threatened is possibly appropriate, 
    but for which conclusive data on biological vulnerability and threats 
    are not currently available to support a listing proposal. Category 1 
    applies to taxa for which the Service has on file substantial 
    information on biological vulnerability and threats to support 
    proposals to list them as endangered or threatened species.
        On October 24, 1990, the Service received a petition from Dr. Camm 
    Swift, Associate Curator of Fishes at the Los Angeles Museum of Natural 
    History, to list the tidewater goby as endangered (Swift 1990). The 
    petition, status surveys, and accompanying data describe the goby as 
    threatened because of past and continuing losses of coastal and 
    riparian habitats within its historic range. The Service's finding that 
    this petition presented substantial information that the requested 
    action may be warranted was published on March 22, 1991 (56 FR 12146). 
    Following this finding, the Service initiated a status review on the 
    tidewater goby.
        Section 4(b)(3)(B) of the Endangered Species Act (Act), as amended 
    in 1982, requires the Secretary to make a finding within 12 months of 
    the date a petition is received as to whether or not the requested 
    action is warranted. On December 11, 1992, the Service published a 
    proposal to list the tidewater goby as an endangered species (57 FR 
    58770). The proposed rule constituted the 12-month finding that the 
    petitioned action was warranted.
    
    Summary of Comments and Recommendations
    
        In the December 11, 1992 proposed rule, all interested parties were 
    requested to submit factual reports or information that might 
    contribute to the development of a final determination. Appropriate 
    Federal and State agencies, county governments, scientific 
    organizations, and other interested parties were contacted and 
    requested to comment. Newspaper notices were published in The Los 
    Angeles Times on January 1, 1993, The San Francisco Sunday Examiner and 
    Chronicle on January 3, 1993, and The San Diego Union-Tribune on 
    February 4, 1993. The public comment period ended on February 9, 1993. 
    A total of 548 comments were received. The Service received one letter 
    from a Federal agency, three letters from State offices, and five from 
    city or county agencies. Five hundred and ten of the comments were post 
    cards from individuals urging support for the listing of the species. 
    The Service received 29 letters from individuals and private 
    organizations. Of those, only one expressed an opinion in opposition to 
    listing the tidewater goby as endangered.
        The National Park Service (Santa Monica Mountains National 
    Recreation Area) stated support for the listing of the tidewater goby 
    as endangered and suggested locations within the recreation area 
    boundaries that may be candidates for reintroduction of the species. 
    The National Park Service also sought assistance from the Service in 
    determining potential habitat locations on lands not under public 
    ownership that may be acquired under its land acquisition program.
        Three California State agencies offered comments. The Topanga-Las 
    Virgenes Resource Conservation District, a subdivision of State 
    government, expressed full support for the listing of the goby. The 
    California Coastal Commission stated, ``The acute vulnerability of the 
    tidewater goby to man-induced changes of estuarine habitat makes the 
    development of comprehensive management strategies and plans, including 
    development of recovery plans, for this species imperative.'' The 
    California Department of Fish and Game submitted information pertaining 
    to a project to reestablish a population of tidewater gobies on Waddell 
    Creek Lagoon. The population was reintroduced in the fall of 1991 and 
    subsequently sampled in November 1992. Gobies were reported from three 
    sites in the lagoon. The Department will continue to obtain information 
    on that population as it is surveyed.
        Five letters of information were received from city or county 
    agencies. Two of these, one from the County of Santa Barbara Resource 
    Management Department and one from the City of Santa Cruz, detailed 
    population occurrences that were already known to the Service. Two 
    letters from the cities of San Buenaventura and Santa Barbara cited 
    possible impacts to goby habitat due to proposed or ongoing projects. 
    These letters listed threats that are discussed under Factor A in the 
    ``Summary of Factors Affecting the Species'' section. The Santa Barbara 
    County Flood Control and Water Conservation District stated support for 
    listing, but expressed concerns regarding the designation of critical 
    habitat.
        The Environmental Defense Center identified three issues concerning 
    the proposed rule.
        Issue 1: The critical habitat finding failed to meet the standards 
    of section 4 of the Endangered Species Act and under Northern Spotted 
    Owl v. Lujan, 758 F. Supp. 621 (W.D. Wash. 1991).
        Service Response: The Service concurs that critical habitat should 
    be designated for the tidewater goby. Information needed to complete 
    required economic impact analyses consists of identifying Federal 
    actions that might be precluded or modified by the destruction/adverse 
    modification standard but not by the jeopardy standard. Moreover, it 
    will be necessary to describe how these actions may be modified by 
    application of the destruction/adverse modification standard. This 
    information will provide a basis for analyses on the economic effects 
    of designating critical habitat.
        Issue 2: Without critical habitat, the Service lacks jurisdiction 
    to prevent or modify certain actions affecting the tidewater goby.
        Service Response: Although in some cases critical habitat may 
    provide protection otherwise unavailable through the jeopardy standard, 
    jurisdiction is available through the jeopardy standard and section 9, 
    both of which may be aggressively applied to protect listed species.
        Issue 3: The Service should at minimum propose the Santa Ynez 
    estuary as critical habitat now.
        Service Response: The Service intends to propose as critical 
    habitat all tidewater goby habitat that may be essential to the 
    species' conservation, as opposed to the piecemeal approach advocated 
    in the recommendation to propose one estuary. In the interim, the Santa 
    Ynez estuary is owned by the U.S. Air Force, which is subject to the 
    section 7(a)(1) affirmative conservation mandate and the prohibitions 
    against jeopardy contained in section 7(a)(2).
    
    Summary of Factors Affecting the Species
    
        After a thorough review and consideration of all information 
    available, the Service has determined that the tidewater goby should be 
    classified as an endangered species. Procedures found at section 4 of 
    the Endangered Species Act (16 U.S.C. 1531 et seq.) and regulations (50 
    CFR part 424) promulgated to implement the listing provisions of the 
    Act were followed. A species may be determined to be an endangered or 
    threatened species due to one or more of the five factors described in 
    section 4(a)(1). These factors and their application to the tidewater 
    goby (Eucyclogobius newberryi) are as follows:
        A. The present or threatened destruction, modification, or 
    curtailment of its habitat or range. Coastal development projects that 
    result in the loss of coastal saltmarsh habitat are currently the major 
    factor adversely affecting the tidewater goby. Coastal marsh habitats 
    have been drained and reclaimed for residential and industrial 
    developments. Waterways have been dredged for navigation and harbors 
    resulting in permanent and direct losses of wetland habitats, as well 
    as indirect losses due to associated changes in salinity. Coastal road 
    construction projects have severed the connection between marshes and 
    the ocean, resulting in unnatural temperature and salinity profiles 
    that the tidewater goby cannot tolerate.
        Furthermore, upstream water diversions adversely affect the 
    tidewater goby by altering downstream flows, thereby diminishing the 
    extent of marsh habitats that occurred historically at the mouths of 
    most rivers and creeks in California. Alterations of flows upstream of 
    coastal lagoons have already changed the distribution of downstream 
    salinity regimes. Since the tidewater goby has relatively narrow 
    salinity tolerances, changes in salinity distributions due to upstream 
    water diversions may adversely affect both the size and distribution of 
    goby populations (D. Holland, Univ. of Southwestern Louisiana, pers. 
    comm., 1991).
        Historically, the tidewater goby occurred in at least 87 of 
    California's coastal lagoons (Swift et al. 1989). Since 1900, it has 
    disappeared from approximately 50 percent of formerly occupied lagoons. 
    A rangewide status survey conducted in 1984 found that 22 historic 
    populations of tidewater goby had been extirpated (Swift et al. 1989). 
    Only 5 years later, a status survey documented the disappearance of an 
    additional 21 populations. In the San Francisco Bay area, 9 of 10 
    previously identified populations have disappeared (Swift et al. 1989, 
    1990). Losses in the southern part of the State have been the greatest, 
    including 74 percent of the coastal lagoons south of Morro Bay. Three 
    populations currently remain south of Ventura County. Since 1989, three 
    additional tidewater goby populations have been lost in San Luis Obispo 
    and Santa Cruz Counties (Swift et al. 1989, 1990). Five small 
    populations have been rediscovered since 1984, but the overall losses 
    indicate a decline of 35 percent rangewide in 6 years (Holland 1991a, 
    1991b, 1991c; Swift et al. 1991).
        Of the 43 remaining populations of tidewater gobies identified by 
    Swift et al. (1990), most are small and threatened by a variety of 
    human and natural factors. According to Swift et al. (1990), only eight 
    extant localities contain populations that are considered large enough 
    and free enough from habitat degradation to be safe for the immediate 
    future. These areas are all located north of San Francisco Bay. The 
    remaining lagoons are so small or modified that tidewater goby 
    populations are restricted in distribution and vulnerable to 
    elimination (Swift et al. 1989, 1990). The number of extirpated 
    localities of gobies has left remaining populations so widely separated 
    throughout most of the species' range that recolonization is unlikely.
        Several specific proposed and ongoing coastal development 
    activities threaten habitats supporting tidewater gobies, including 
    road widening and bridge replacement projects along Highway 101, water 
    diversion projects in San Luis Obispo County, expansion of several 
    State Park Recreation areas in Santa Barbara and San Luis Obispo 
    Counties, and hotel and golf course developments in San Luis Obispo and 
    Marin Counties.
        In addition to these specific threats, the tidewater goby is 
    vulnerable throughout its remaining range because of the loss of 
    coastal marsh, as noted above, and because of other effects of water 
    diversions as well. In addition to restricting the goby's overall range 
    by altering downstream salinities, water diversions and alterations of 
    water flows may negatively impact the species' breeding and foraging 
    activities. Gobies in southern and central California breed primarily 
    in sand/mud substrates and apparently avoid areas that contain large 
    amounts of decaying vegetation (Holland 1991b). Reductions in water 
    flows may allow aggressive plant species to colonize the otherwise bare 
    sand/mud substrates of coastal lagoon margins, thus degrading the 
    habitat quality for the goby. Decreases in stream flows also reduce the 
    deep stream pools utilized by gobies venturing upstream from lagoons. 
    In San Luis Obispo County alone, the effects of drought, either 
    directly or exacerbated by upstream water diversions, have been 
    responsible for the extirpation of at least three populations of gobies 
    between 1986 to 1990 (K. Worcester, California Department of Fish and 
    Game, pers. comm., 1991).
        The tidewater goby is also adversely affected by groundwater 
    overdrafting and discharge of agricultural and sewage effluents. For 
    example, in Santa Barbara County, increased groundwater pumpage and 
    siltation from topsoil runoff in the San Antonio Creek drainage has 
    significantly affected areas immediately upstream of occupied goby 
    habitat (i.e., Barka Slough) (C. Swift, Los Angeles County Museum of 
    Natural History, pers. comm., 1991). Enrichment by agricultural and 
    sewage effluents may cause algal blooms and deoxygenation that restrict 
    habitable areas of lagoons utilized by tidewater gobies, especially in 
    summer (Swift et al. 1989). The potential for these factors to degrade 
    remaining goby habitats has also been noted at all three extant 
    localities south of Ventura County (D. Holland, pers. comm., 1991) and 
    at several sites along the central California coast (T. Taylor, 
    California State Parks and Recreation, pers. comm., 1991; K. Worcester, 
    pers. comm., 1991).
        The tidewater goby is further threatened by channelization of the 
    rivers it inhabits. Because most of the goby's localities have been 
    moderately to extremely channelized, winter floods scour the species 
    out of the restricted channelized areas where no protection is afforded 
    from such high flows. This type of event was responsible for the 
    disappearance of gobies from Waddell Creek lagoon in the winter 1972-73 
    (C. Swift, pers. comm., 1991).
        Finally, cattle grazing and feral pig activity present a threat to 
    the existence of the tidewater goby. These activities have resulted in 
    increased sedimentation of coastal lagoons and riparian habitats, 
    removal of vegetative cover, increased ambient water temperatures, and 
    elimination of plunge pools and collapsed undercut banks utilized by 
    tidewater gobies. In San Luis Obispo County, increased sedimentation 
    into Morro Bay has significantly accelerated the conversion of wetland 
    habitats to upland habitats (Josselyn et al. 1989). Presently, cattle 
    continue to graze freely both upstream and in many of the coastal 
    lagoons supporting tidewater gobies (K. Worcester, pers. comm., 1991).
        B. Overutilization for commercial, recreational, scientific, or 
    educational purposes. Not known to be applicable.
        C. Disease or predation. Over the past 20 years, at least 60 
    species of exotic fishes have been introduced to the western United 
    States, 59 percent of which are predatory (Hayes and Jennings 1986, 
    Jennings 1988). The introduction of exotic predators to southern 
    California waters has been facilitated by the interbasin transport of 
    water (e.g., California Aqueduct). Introduced predators, particularly 
    centrarchid fishes, may have contributed to the elimination of the 
    tidewater goby from several localities in California (Swift et al. 
    1989). The present day absence of the tidewater goby from the San 
    Francisco delta area may well be explained by the presence of 
    introduced predators such as striped bass (Morone saxatilis) and native 
    predators including the Sacramento perch (Archoplites interruptus) 
    (Swift et al. 1989, 1990). Two of the most recent disappearances of 
    gobies from San Luis Obispo County (Old Creek) and San Diego County 
    (San Onofre Creek) are likely due to the presence of exotic largemouth 
    bass (Micropterous salmoides) and green sunfish (Lepomis cyanellus), 
    respectively. Natural predation on gobies by rainbow trout 
    (Oncorhynchus mykiss) has been documented (Swift et al. 1989). Other 
    non-native predators, specifically crayfish (Cambarus spp.) and 
    mosquitofish (Gambusia spp.), may also threaten goby populations 
    through direct predation on adults, larvae, or eggs.
        D. The inadequacy of existing regulatory mechanisms. Section 10 of 
    the Rivers and Harbors Act and section 404 of the Clean Water Act 
    regulate the placement of dredge and fill materials into waters of the 
    United States. Under section 404, nationwide permits, which undergo 
    minimal public and agency review, can be issued for projects involving 
    less than 10 acres of waters of the United States and adjacent 
    wetlands, unless a listed species may be adversely affected. Individual 
    permits, which are subject to more extensive review, are required for 
    projects that affect greater than 10 acres.
        The U.S. Army Corps of Engineers (Corps) is the agency responsible 
    for administering the section 10 and section 404 programs. The Service, 
    as part of the section 404 review process, provides comments on both 
    predischarge notices for nationwide permits and public notices for 
    individual permits. The Service's comments are only advisory, although 
    procedures exist for elevation when disagreements between the agencies 
    arise. In practice, the Corps' actions under section 10 and section 404 
    are insufficient to protect the tidewater goby.
        Most projects within the range of the tidewater goby considered in 
    this proposal may require approval from the Corps as currently 
    described in section 404 of the Clean Water Act. Projects proposed in 
    coastal lagoons may also require a permit under section 10 of the 
    Rivers and Harbors Act. Federal listing of this species requires 
    Federal agencies to insure their actions are not likely to jeopardize 
    the tidewater goby's continued existence or destroy or adversely modify 
    any habitat that is designated as critical.
        The National Environmental Policy Act and California Environmental 
    Quality Act require an intensive environmental review of projects that 
    may adversely affect Federal candidate species. However, project 
    proponents are not required to avoid impacts to these species, and 
    proposed mitigation measures are frequently not adequately implemented. 
    As with section 404 permits, the Service's comments through these 
    environmental review processes are only advisory.
        The California Coastal Act regulates the approval of developments 
    within the coastal zone. Although a significant slowing in wetland 
    losses has occurred, the continued loss and degradation of coastal 
    wetlands since the California Coastal Act was enacted in 1974 attests 
    to the limitations of this legislation.
        E. Other natural or manmade factors affecting its continued 
    existence. By far, the most significant natural factor adversely 
    affecting the tidewater goby is drought and resultant deterioration of 
    coastal and riparian habitats. California has recently experienced 5 
    consecutive years of lower than average rainfall. These drought 
    conditions, when combined with human induced water reductions (i.e., 
    diversions of water from streams, excessive groundwater withdrawals), 
    have degraded coastal and riparian ecosystems and have created 
    extremely stressful conditions for most aquatic species. Formerly large 
    populations of tidewater gobies have declined in numbers because of the 
    reduced availability of suitable lagoon habitats (i.e., San Simeon 
    Creek, Pico Creek), others disappeared when the lagoons dried (i.e., 
    Santa Rosa Creek). In San Luis Obispo County alone, 6 of 20 populations 
    of tidewater gobies were extirpated between 1984 and 1989 because of 
    drought, water diversions, and pollution (K. Worcester, pers. comm., 
    1991).
        Habitat degradation and losses of the tidewater goby from weather 
    related phenomena commonly occur due to the restriction of the species 
    to coastal lagoon systems and its dependence on freshwater inflows. 
    Events such as river flooding and heavy rainfall have been reported to 
    destroy goby burrows and wash gobies out to sea. Storm surges that 
    enter a lagoon may also adversely affect entire goby populations by 
    rapidly changing its salinity.
        The tidewater goby was undoubtedly subjected to such natural flood 
    events even before major human alteration of drainage basins. As 
    mentioned under Factor A, channelization and urbanization have 
    increased the frequency and perhaps the intensity of such flood events. 
    In addition, populations of gobies are becoming more isolated from one 
    another as intervening populations are extirpated, thus further 
    decreasing the likelihood of successfully colonizing and reestablishing 
    a population lost to a ``natural'' flood.
        Competition with introduced species is a potential threat to the 
    tidewater goby. Although problems have not been documented so far, the 
    spread of two introduced oriental gobies (yellowfin goby (Acanthogobius 
    flavimanus) and chameleon goby (Tridentiger trigonocephalus)) may have 
    a detrimental effect on the tidewater goby. According to Swift et al. 
    (1990), the chameleon goby was recently found in Pyramid Lake, probably 
    imported with central California water. If this goby becomes 
    established in the Santa Clara River as other imported species have 
    (e.g., prickly sculpin (Cottus asper)), the tidewater goby population 
    at the mouth of the Santa Clara River may be at risk.
        The Service has carefully assessed the best scientific and 
    commercial information available regarding the past, present, and 
    future threats faced by this species in determining to make this rule 
    final. The tidewater goby has been extirpated from nearly 50 percent of 
    the lagoons within its historic range, including 74 percent of the 
    lagoons south of Morro Bay. Forty-three populations remain; however, 
    only six are large in number and reasonably free from immediate 
    threats. Based on this evaluation, the preferred action is to list the 
    tidewater goby as endangered. The tidewater goby has experienced a 
    substantial decline throughout its historic range and faces threats 
    indicating that this downward trend is likely to continue. This species 
    lives within specific habitat zones that have been, and will continue 
    to be, targeted for development and degradation by human activities. 
    The goby is extremely vulnerable to adverse habitat modification and 
    water quality changes. The tidewater goby is in imminent danger of 
    extinction throughout its range and requires the full protection of 
    listing as endangered under the Act to survive. For reasons discussed 
    below, the Service is not proposing to designate critical habitat for 
    this fish species at this time.
    
    Critical Habitat
    
        Section 4(a)(3) of the Act, as amended, requires that, to the 
    maximum extent prudent and determinable, the Secretary designate 
    critical habitat concurrently with determining a species to be 
    endangered or threatened. Furthermore, the Service is to designate 
    critical habitat on the basis of the best scientific and commercial 
    data available after taking into consideration the economic and other 
    relevant impacts of specifying an area as critical habitat (16 U.S.C. 
    1533(b)(2)). In the case of the tidewater goby, critical habitat is not 
    presently determinable. A final designation of critical habitat 
    requires detailed information on the possible economic effects of such 
    a designation. The Service does not currently have sufficient 
    information needed to perform the economic analysis. A delay in the 
    determination to list the species to gather additional information and 
    perform analyses would not serve the needs of the species. Information 
    is needed on actions that may be proposed within tidewater goby habitat 
    and the degree to which a designation of critical habitat may affect 
    these actions over and above effects associated with listing the goby 
    as endangered (i.e., the jeopardy standard alone). It will also be 
    necessary to determine how and to what extent application of the 
    destruction/adverse modification standard will change various Federal 
    actions. These data will be used in the economic analyses to determine 
    the economic effects of critical habitat designation.
    
    Available Conservation Measures
    
        Conservation measures provided to species listed as endangered or 
    threatened under the Endangered Species Act include recognition, 
    recovery actions, requirements for Federal protection, and prohibitions 
    against certain activities. Recognition through listing encourages and 
    results in conservation actions by Federal, State, and private 
    agencies, groups, and individuals. The Endangered Species Act provides 
    for possible land acquisition and cooperation with the States and 
    requires that recovery actions be carried out for all listed species. 
    The protection required of Federal agencies and the prohibitions 
    against taking and harm are discussed, in part, below.
        Section 7(a) of the Act, as amended, requires Federal agencies to 
    evaluate their actions with respect to any species that is proposed or 
    listed as endangered or threatened and with respect to its critical 
    habitat, if any is being designated. Regulations implementing this 
    interagency cooperation provision of the Act are codified at 50 CFR 
    part 402. Section 7(a)(2) requires Federal agencies to ensure that 
    activities they authorize, fund, or carry out are not likely to 
    jeopardize the continued existence of such a species or to destroy or 
    adversely modify its critical habitat. If a Federal action may affect a 
    listed species or its critical habitat, the responsible Federal agency 
    must enter into formal consultation with the Service.
        A number of Federal agencies or departments control lands that 
    support the tidewater goby. These include the Department of Defense 
    (U.S. Army Corps of Engineers, U.S. Navy, U.S. Air Force, and U.S. 
    Marine Corps), Department of Agriculture (U.S. Forest Service), and 
    Department of the Interior (National Park Service and U.S. Fish and 
    Wildlife Service). Federal actions that may be affected by this 
    determination would be the funding or authorization of projects within 
    the species' habitat, including the construction of roads, bridges, and 
    dredging projects subject to section 404 of the Clean Water Act (33 
    U.S.C. 1344 et seq.) and section 10 of the Rivers and Harbors Act of 
    1899 (33 U.S.C. 401 et seq.), and special use permits. Other Federal 
    actions that are subject to environmental review under the National 
    Environmental Policy Act would also require consultation with the 
    Service. Projects on federally owned land would also be subject to the 
    provisions of section 7 of the Endangered Species Act.
        The Act and implementing regulations found at 50 CFR 17.21 set 
    forth a series of general prohibitions and exceptions that apply to all 
    endangered wildlife. These prohibitions, in part, would make it illegal 
    for any person subject to the jurisdiction of the United States to take 
    (includes harass, harm, pursue, hunt, shoot, wound, kill, trap, 
    capture, or collect; or attempt any of these), import or export, 
    transport in interstate or foreign commerce in the course of commercial 
    activity, or sell or offer for sale in interstate or foreign commerce 
    any listed species. It also is illegal to possess, sell, deliver, 
    carry, transport, or ship any such wildlife that has been taken 
    illegally. Certain exceptions apply to agents of the Service and State 
    conservation agencies.
        The Act and 50 CFR 17.22 and 17.23 also provide for the issuance of 
    permits to carry out otherwise prohibited activities involving 
    endangered wildlife species under certain circumstances. Such permits 
    are available for scientific purposes, to enhance the propagation or 
    survival of the species, for incidental take in connection with 
    otherwise lawful activities, and for economic hardship under certain 
    circumstances. Requests for copies of the regulations on listed plants 
    and wildlife and inquiries regarding them may be addressed to the U.S. 
    Fish and Wildlife Service, Ecological Services, Permit Branch, 911 N.E. 
    11th Avenue, Portland, Oregon 97232-4181, telephone 503/231-6241, FAX 
    503/231-6243.
    
    National Environmental Policy Act
    
        The Fish and Wildlife Service has determined that an Environmental 
    Assessment or Environmental Impact Statement, as defined under the 
    authority of the National Environmental Policy Act of 1969, need not be 
    prepared in connection with regulations adopted pursuant to section 
    4(a) of the Endangered Species Act of 1973, as amended. A notice 
    outlining the Service's reasons for this determination was published in 
    the Federal Register on October 25, 1983 (48 FR 49244).
