OPINION
Thе Center for Biological Diversity and the Turtle Island Restoration Network (collectively, the “Center”) appeal the district court’s grant of summary judgment in favor of the National Marine Fisheries Service (“Fisheries Service”). This case presents the question of whether the issuance of fishing permits by the Fisheries Service pursuant to the High Seas Fishing Compliance Act (“Compliance Act”), 16 U.S.C. § 5501-5509, invokes the consultation requirements of the Endangered Species Act (“ESA”). The Center brought this action pursuant to the citizen suit provision of the ESA alleging that the Fisheries Service was violating the consultation and take provisions of the ESA through the issuance of fishing permits to longline fishing vessels in California. The Center asserts that longline fishing results in harm to several endangered and protected species including several varieties of sea turtles and sea birds that become entangled in the longlines. The district court found that the issuance of permits under the Compliance Act does not invoke the cоnsultation requirements of the ESA because the Fisheries Service did not have Sufficient discretion to condition permits *971 for the benefit of a protected species. However, we conclude that the plain language of the Compliance Act does contain ample discretion to allow the conditioning of permits for the benefit of protected species, and we reverse the judgment of the district court.
I
Procedural and Factual Background
This case concerns United States-flagged vessels that engage in longline fishing practices on the high seas of the Pacific Ocean and land their catch in California. Longline fishing involves the use of a line that stretches several miles from a vessel and is anchored to appropriate depths. Attached to the longline are many additional lines to which weights and baited hooks are fastened. A single longline may deploy several thousand hooks at one time. Longline fishing vessels mainly target swordfish but also fish for other migratory speciеs, such as varieties of tuna and shark.
Until recently, most U.S. vessels that engaged in longline fishing were based in Hawaii. In November 1999, a district court in Hawaii issued a preliminary injunction restricting longline fishing under the Hawaii Fishery Management Plan throughout much of the North Pacific. Center for Marine Conservation v. National Marine Fisheries Service, (Civ. No. 99-00152(DAE)(D.Hawaii)). 1 Pursuant to the requirements of the ESA, the Fisheries Service issued a biological opinion concluding that the operation of the Hawaii Fishery Management Plan would jeopardize the continued existence of the several protected species of sea turtles. Subsequent revisions to the Hawaii Fisheries Management Plan eliminated the Hawaii-based longline swordfish fishing industry. Consequently, numerous boats from Hawaii relocated to California ports. 2
On July 6, 2000, the Center sent a letter to the Secretary of Commerce, giving a 60-day notice of intent to sue for violations by the Fisheries Service of Sections 7 and 9 of the Endangered Species Act. 3 The Centеr first contended that the Fisheries Service is violating Section 7 of the ESA by failing to initiate and complete consultations concerning the effects on threatened and endangered species of longline fishing by U.S. vessels, under permits issued by the Fisheries Service. The protected species designated included the leatherback, 4 loggerhead, 5 olive ridley, 6 and green, 7 sea *972 turtles, as well as the short-tailed albatross. 8 Second, the Center contended that the Fisheries Service failed to comply with Section 9 of the ESA by granting permits to private parties that result in thе “take” of threatened or endangered species. It contended that a governmental body under whose authority an actor exacts a taking of an endangered or threatened species can also be held responsible for the taking under Section 9.
On September 1, 2000, the Fisheries Service’s Regional Administrator sent a letter in response, stating that under the Fisheries Service’s interpretation of the Compliance Act, the agency lacked discretion in issuing the fishing pеrmits to impose conditions that further the conservation of protected species; therefore, the consultation provisions of the ESA were not implicated. Further, the agency was developing a fishery management plan for high seas migratory species and that an ESA consultation would be conducted during that administrative process to consider the impact of California’s longline fleet on threatened and endangered species. The Fisheries Service stаted that it would investigate any take of protected species by fisherman engaged in the high seas fishery. The Center then filed suit against the Fisheries Service asserting the three claims outlined in its notice letter.
The district court resolved the case on cross-motions for summary judgment. The court rejected the Center’s claims that the Fisheries Service was in violation of ESA Section 7 by not consulting prior to the issuance of the permits. It held that the agency lacked discretion in issuing the permits tо impose conditions furthering the conservation of protected species and that nothing in the Compliance Act “provides the Secretary with the authority to place such conditions on permits.”

Standard of Review
A district court’s grant of summary judgment is reviewed de novo.
Sierra Club v. Babbitt,
III
Statutory Framework
A. High Seas Fishing Compliance Act
Prior to 1993, the United States had entered into numerous bilateral and multilateral agreements providing for the use and protection of various high seas fishery and marine resources. Many of these agreements provided for the protection of endangered and protected species. The restrictions that were imposed by these agreements were аpplicable only to vessels flagged by countries that were signatories to the agreements. In order to avoid the restrictions, many vessels reflagged in countries that were not party to these agreements.
In 1993, the United Nation’s Food and Agriculture Organization addressed the problem of reflagging by negotiating the Agreement to Promote Compliance with International Conservation and Management Measures by Fishing Vessels on the High Seas (the “Agreement”). The Agreement required each рarty to “take such measures as may be necessary to ensure that fishing vessels entitled to fly its flag do not engage in any activity that undermines the effectiveness of international conservation and management measures.”
In 1995, the United States enacted the High Seas Fishing Compliance Act (“Compliance Act”), for the purpose of implementing the “Agreement to Promote Compliance with International Conservation and Management Measures by Fishing Vessels on the High Seas” and “to establish a system of permitting, reporting, and regulation for vessels of the United States fishing on the high seas.” 16 U.S.C. § 5501. The Compliance Act requires United States vessels to obtain permits to engage in fishing operations on the high seas, authorizes the Secretary of Commerce to promulgate regulations to implement the Act, proscribes unlawful activities, and establishes enforcement mechanisms. 16 U.S.C. §§ 5504-5506. Further, it imposes conditions and restrictions on the permits that are issued to fishing vessels. 16 U.S.C. § 5503.
B. The Endangered Species Act
The Endangered Sрecies Act (“ESA”) was enacted in 1973 to prevent the extinction of various fish, wildlife, and plant species. The ESA is the “most comprehensive legislation for the preservation of endangered species ever enacted by any nation.”
Tennessee Valley Auth. v. Hill,
Section 7(a)(2) of the ESA imposes a procedural duty on federal agencies to consult with either the Fisheries Service or the FWS before engaging in a discretionary action, which may affect listed species. 16 U.S.C. § 1536(a)(2); 50 C.F.R. §§ 402.14, 402.01(b). When the acting agency is either the Fisheries Service or the FWS, the obligation to consult is not relieved, instead, the agency must consult within its own agency to fulfill its statutory mandate. See id. The purpose of the consultation procedure is to allow either the Fisheries Service or the FWS to determine whether the federal action is likely to jeopardize the survival of a protected species or result in the destruction of its critical habitat, and if so, to identify reasonable and prudent alternatives that will avoid the action’s unfavorable impacts. See 16 U.S.C. § 1536(b)(3)(A). 9
IV
Analysis
As a threshold question, we must address whether the issuance of fishing permits by the Fisheries Service under the Compliance Act constitutes “agency аction” implicating the ESA.
See Natural Resources Defense Council v. Houston,
The Fisheries Service and the FWS jointly promulgated the ESA implementing regulations, which state in relevant part, that “Section 7 and the requirements of this part apply to all action in which there is
discretionary Federal involvement or control.”
50 C.F.R. § 402.03 (emphasis added). This court has held that the discretionary control retained by the federal agency must have the ability to inure to the benefit of a protected species.
Environmental Prot. Info. Ctr. v. Simpson Timber Co.,
*975
The district court found that there was not sufficient discretionary control retained by the Fisheries Service while issuing the permits to inure to the benefit of protected species. The district court recognized that “some” discretion was retained by the Fisheries Service but “[n]othing in the Compliance Act provides the Secretary [of Commerce] with the authority to place conditions on permits that inure to the benefit of protected species.”
Center for Biological Diversity,
“[I]t is our duty to give effect, if possible, to every clause and word of a statute rather than to emasculate an entire section.”
Bennett v. Spear,
When interpreting a statute, “[i]f the intent of Congress is clear, that is the end of the matter; for the court, as well as the agency must give[ ] effect to the unambiguously expressed intent of Congress.”
Chevron, U.S.A. Inc. v. Natural Resources Defense Council,
The plain language of the Compliance Act provides Fisheries Service with amрle discretion to protect listed species. The intent of the Compliance Act was to implement the “Agreement to Promote Compliance with International Conservation and Management Measures by Fishing Vessels on the High Seas” and “to establish a system of permitting, reporting, and regulation for vessels of the United States fish *976 ing on the high seas.” 16 U.S.C. § 5501. The “Conditions” subsection provides that “[t]he Secretary shall establish such conditions and restrictions on each permit issued under this section as аre necessary and appropriate to carry out the obligations of the United States under the Agreement, including but not limited to ” the markings of the boat and reporting requirements. 16 U.S.C. § 5503(d) (emphasis added). 11
We hold that the Compliance Act is not ambiguous, and Congress’s intent is clear from the plain language of the statute, therefore, we would not defer to the Fisheries Service’s interpretation, even if the opinion letter were a document entitled to
Chevron-style
deference.
Chevron,
As the implementing legislation for the Agreement, the Compliance Act expressly defines the term “international conservation and management measures” to mean “measures to conserve or manage one or more species of living marine resources.” 16 U.S.C. § 5502(5). Among many others, one such measure is the Inter-American Convention for the Protection and Conservation of Sea Turtles which was designed to promote “the protection, conservation, and recovery of sea turtle populations and of the habitats on which they depend.” The Sea Turtlе Convention seeks to reduce to the greatest extent practicable the inei-dental capture, retention, harm and mortality of sea turtles.
The district court and the Fisheries Service reliance on this court’s holdings in
Sierra Club
and
Simpson Timber
is in error. In
Sierra Club,
a private timber company, pursuant to a right-of-way agreement with the Bureau of Land Management (“BLM”), sought to build a road on public land, which potentially impacted the northern spotted owl.
In
Simpson Timber,
this court addressed whether the FWS retained sufficient discretionary control over an incidental take permit issued to Simpson Timber to require FWS to reinitiate consultation when two additional species found on
*977
Simpson Timber’s land were listed as threatened after the permit was issued.
Simpson Timber and Sierra Club faсtually differ from the present case because they involve situations where the agency activity had been completed and there was no ongoing agency activity, therefore, the consultation requirements of the ESA were not invoked. Conversely, the Fisheries Service’s continued issuance of fishing permits under the Compliance Act constitutes ongoing agency action, thus, under the plain language of the Compliance Act, discretion is retained by the federal agency.
More closely analogous is our decision in
Pacific Rivers Council v. Thomas,
in which we held that the Forest Service was obligated to consult with the Fisheries Service regarding the listing of the chi-nook salmon.
The Compliance Act entrusts the Fisheries Service with substantial discretion to condition permits to inure to the benefit of listed species. Whether the Fisheries Service must condition permits to benefit listed species is not the question before this court, rather, the question before us is whether the statutory language of the Compliance Act confers sufficient discretion to the Fisheries Service so that the agency could condition permits to benefit listed species. We hold that the statute confers such discretion and because it does so, the ESA requires that the Fisheries Service conduct consultation to assess the potential impact to protected species.
V
Conclusion
In light of our holding that the issuance of permits under the Compliance Act is discretionary agency action, we reverse the district court and conclude that the Fisheries Service is required to conduct consultation to meet its obligations under Section 7 of the ESA. Further, we remand the claims brought under Section 9 of the ESA for further proceedings in light of our decision that the issuance of the permits constitutes discrеtionary agency action.
REVERSED AND REMANDED.
Notes
. Hawaiian longline fishing is managed under the federal Fishery Management Plan for Pelagic Fisheries in the Western Pacific Region. Vessels that are under the Hawaii Fishery Management Plan fish both within the U.S. 200-mile exclusive economic zone, as well as in the high seas. As long as the vessels are unloading their catch in Hawaii, these vessels are subject to the rules and regulations of Hawaii’s Fishery Management Plan.
. The record shows that since December 1999, at least 40 longline boats originating in Hawaii have unloaded their catch in California ports. The quantity of swordfish landed at San Pedro, California increased from 1.5 million pounds in 1999 to 2.6 million pounds in 2000.
. The 60-day notice of intent to sue was sent to comply with the citizen suit provision of 16 U.S.C. § 1540(g)(2).
. The leatherback sea turtle (Dermochelys co-riácea ) is listed as endangered by the ESA throughout its global range. 50 C.F.R. § 17.11. The leatherback is the largest sea turtle weighing between 700 and 2000 pounds as an adult, and ranging from four to eight feet in length. Unlike many other sea turtles, the leatherback has a soft rubbery shell. The sрecies feeds primarily on jellyfish and is capable of diving to depths greater than 3,000 feet.
. The loggerhead sea turtle (Caretta caretta) is listed as a threatened species under the ESA. 50 C.F.R. § 17.11. The loggerhead is characterized by a reddish brown, bony cara *972 pace, with a comparatively large head, up to 25 centimeters wide. Adult loggerheads range in weight between 150 and 400 pounds and are typically 2.5 to 3.5 feet long. The loggerhead feeds primarily on mollusks and crustaceans. All loggerhead turtles in the Pacifiс breed in the western Pacific.
. The olive ridley sea turtle (Lepidochelys oli-vácea) is listed as threatened by the ESA throughout its global range, however the Mexican nesting population is listed as endangered. 50 C.F.R. § 17.11. The olive ridley is one of the smallest sea turtles and nests in the Indian Ocean along the coast of India and in the eastern Pacific along the coasts of Mexico and Central America. It generally feeds on mollusks and crustaceans. The primary threats to the species are mortality from fishing and overharvest of nesting females and their eggs.
. The green sea turtle (Chelonia mydas) is listed as threatened by the ESA, except for the population breeding on the Pacific coast of Mexico, which is listed as endangered. 50 C.F.R. § 17.11. The green sea turtle is generally regarded as comprising two types, the eastern Pacific “black turtle” and the green turtle throughout the central and western Pacific. The species nests in Mexico, Central America, the Galapagos, Hawaii and in the South Pacific.
.The short-tailed albatross (Phoebastria alba-trus ) is listed as an endangered species by the ESA. 50 C.F.R. § 17.11. The shоrt-tailed albatross is the largest of the seabirds of the North Pacific with a wingspan exceeding nine feet. The species currently breeds on only a handful of islands in Japan. Once numbering in the millions, the species now numbers approximately 1300 of the short-tailed albatross. The species was brought near extinction by feather hunters at the turn of the twentieth century.
. If a contemplated agency action may affect a protected species, then the "acting agency” must сonsult with either the Fisheries Service or the FWS, either formally or informally. 50 C.F.R. § 402.14(a); 16 U.S.C. § 1536(a)(4). The agency first prepares a biological assessment, in which it evaluates the potential effects of an action on the protected species and its critical habitat. 50 C.F.R. § 402.12(a). If the agency determines that its action is "likely to adversely affect” a protected species, it must engage in formal consultation. See id. If the agency determines that its action is "not likely to adversely affeсt” a protected species, it may attempt informal consultation. See 50 C.F.R. § 402.13(a). In this case, where the Fisheries Service is itself the acting agency, the consultation would be with the same internal units of the Fisheries Service as would be involved with an outside acting agency.
. Even if we were to find that the statute was ambiguous, we conclude that the Fisheries Service’s interpretation of the Compliance Act is not entitled to
Chevron
deference. The Fisheries Service's interpretation was issued in rеsponse to the Center’s 60-day notice letter. "Interpretations such as those in opinion letters — like interpretations contained in policy statements, agency manuals, and enforcement guidelines, all of which lack the force of law — do not warrant Chevron-style deference.”
Christensen v. Harris County,
. The permitting section of the Compliance Act, 16 U.S.C. § 5503(d) states in full:
The Secretary shall establish such conditions and restrictions on each permit issued under this section as are necessary and appropriate to carry out the obligations of the United States under the Agreement, including but not limited to the following: (1) The vessel shall be marked in accordance with the FAO Standard Specifications for the Marking and Identification of Fishing Vessels, or with regulations issued under section 305 of the Magnuson-Stevens Fishery Conservation and Management Act (16 U.S.C. § 1855); and
(2) The permit holder shall report such information as the Secretary by regulation requires, including area of fishing operations and catch statistics. The Secretary shall promulgate regulations concerning conditions under which information submitted under this paragraph may be released.
