- 2 arbitrarily and capriciously approved Washington’s and Oregon’s decision s not to identify any waters experiencing ocean acidification as impaired under Section 303(d) of the Clean Water Act, 33 U.S.C. § 1251 et seq. Having considered the submissions of the parties, the submissions of amici curiae, the administrative record, and the relevant law, and having heard oral argument, the court denies CBD’s motion for summary judgment and grants EPA’s motion for sum mary judgment.
II. BACKGROUND
A. Ocean Acidification Ocean acidification is a long

- term decrease in pH of the earth’s oceans. On a worldwide scale, the primary driver of ocean acidification is carbon uptake: seawater absorbs increased carbon dioxide (CO 2 ) emissions, which leads to a series of chemical
reaction s that make the seawater more acidic. WA

- 00731 (“Pelejero 2010”) at 1. 1 The leading cause of increased atmospheric CO 2 is combustion of fossil fuels. Id. It is
estimated that anthropogenic sources of atmospheric carbon dioxide have increased the acidity of average open

- ocean surface waters by about 30%. WA

- 000 731 (“Feely 2010”) at 4. In coastal regions, other local factors can exacerbate the acidification process. WA

000712 (“Blue Ribbon Panel”) at 4. Regional drivers include both natural phenomena, such as upwelling of deep ocean water and freshwater inputs from rivers, and

1 The parties have provided the court with an electronic copy of the administrative and supplemental administrative records for EPA’s decisions to approve Washington’s and Oregon’s Section 303 lists of impaired waters.

- 3 anthropogenic factors such as nutrient deposits from agricultural runoff, carbon deposits
from stormwater runoff and indust rial pollution, and local emissions of nitrogen and
sulfur oxides. Id. at xii; WA

- 000 712 (“ Feeley 2012 ”) at xii, 33, 37. The changing ocean chemistry affects marine organisms and ecosystems in various ways, with some of the clearest impacts being felt b y organisms whose shells and skeletons are composed of calcium carbonate (CaCO 3 2

- ). Pelejaro 2010 at 1; Blue Ribbon Panel at 10. Specifically, the same chemical reactions that increase the acidity of the ocean reduce the concentration of carbonate ions ( CO 3 2

- ) that shellfish rely on to build shells. Pelejaro 2010 at 1; Blue Ribbon Panel at 10. As a result, marine organisms face difficulties forming and maintaining calcium carbonate

- based shells and skeletons. Pelejaro 2010 at 1; Blue Ribbon Panel at 10 . Additionally, the reduction of precipitated carbonate ions decreases the saturation states of important biominerals such as aragonite
and calcite. Blue Ribbon Panel at 10 ; Feely 2010 at 3. Seawater with such decreased
saturation states is chemically c orrosive and can dissolve the shells of small crustaceans and immature shellfish. Feeley 2010 at 4; Blue Ribbon Panel at 10. Because many small calcifiers provide habitat, shelter, or food for other marine plants and animals, ocean
acidification is also a threat to the broader marine environment. Blue Ribbon Panel at xiv, 16

- 20; see also Feeley 2012.
B. The Clean Water Act The Clean Water Act employs two main regulatory approaches to achieve water quality: (1) technological controls on effluents discharged from point sources and (2) Case 2:13-cv-01866-JLR Document 69 Filed 03/02/15 Page 3 of 701

- 4 water quality standards. This case concerns water quality standards. See Pronsolino v.
Nastri , 291 F.3d 1123, 1126 (9th Cir. 2002); see generally 33 U.S.C. § 1251 et seq. Each state is required to set water qualit y standards for all waters within its
boundaries. Pronsolino , 291 F.3d at 1126; 33 U.S.C. § 131(a)

- (c); 40 C.F.R. § 130.3. These standards, which include designated beneficial uses, numeric and narrative criteria,
and anti

- degradation policies, set goals for improving or maintaining water quality. 40 C.F.R. § 130.3. Wherever attainable, the standards should “provide water quality for the protection and propagation of fish, shellfish, and wildlife and for recreation.” Id. Pursuant to Section 303(d) of the Clean Water Act, every two years each state must generate a list of impaired water bodies for which existing pollution controls are insufficient to meet the water quality standards applicable to the water body. 33 U.S.C. § 1313(d); 40 CFR § 130.7(d)( 1). Section 303 requires the states to submit their impaired waters lists to the EPA for approval. 33 U.S.C. § 1313(d); 40 CFR § 130.7(d)(1). If EPA disapproves a list, it must identify within 30 days the waters that should have been listed as impaired. 33 U.S.C. § 1313(d); 40 CFR § 130.7(d)(1). After a water body is listed as impaired, the state must establish a total maximum daily load (“TMDL”) of each pollutant that the water body can receive and still meet water quality standards. 33 U.S.C. § 131 3(d); 40 CFR § 130.7(d)(1) ; see also
Pronsolino , 291 F.3d at 1127

- 28. The state must incorporate TMDLs into the state’s statutorily required water quality management plan. 33 U.S.C. § 1313(e); Pronsolin o , 291 F.3d at 1128. The state, however, retains the responsibility and discretion to Case 2:13-cv-01866-JLR Document 69 Filed 03/02/15 Page 4 of 701

informational tools that al low the states to proceed from the identification of waters requiring additional planning to the required plans.” Pronsolin o , 291 F.3d at 1128

. In 2010, EPA issued a memorandum recognizing the “seriousness of aquatic life impacts associated with” ocean ac idification, and instructing that “States should list waters not meeting water quality s tandards, including marine pH [water quality criteria] , on th eir 2012 303(d) lists.” WA

C. Washington ’s and Oregon’s Section 303(d) Lists Several of Washington’s water quality standards implicate ocean acidification. Most of Washington’s coastal waters are designated as “extraordinary quality” or “excellent quality” for aquatic life uses, which include “clam, oyster, and mussel rearing and spawning; crustaceans and other shellfish (crabs, shrimp, crayfish, scallops, etc.) rearing and spawning.” WAC 173

Similarly, several of Oregon’s water quality standards implicate ocean acidification. Oregon’s coastal waters are designated for the beneficial uses of “ fish an d aquatic life , ” as well as fishing. See OAR 340

- 041

- 0220 et seq. Narrative water quality criteria provide that “[w]aters of the state must be of sufficient quality to support aquatic species without detrimental changes in the resident biological communi ties,” OAR 340

- 041

- 0011, and that the “creation of . . . conditions that are deleterious to fish or other aquatic life . . . may not be allowed,” OAR 340

- 041

- 0007(10). Oregon’s anti

- degradation policy provides that any existing level of water quality nece ssary to support propagation of fish and shellfish must be maintained and protected. Id. at

- 0004(6). Oregon’s 2010 Section 303(d) list, however, did not identify any coastal or estuarine waters as impaired due to pollutants associated with or condition s attributable to
ocean acidification. EPA originally partially disapp roved Oregon’s 303(d) list, finding that Oregon had not reasonably assemble d and evaluate d all readily available data and

In this lawsuit, CBD challenges EPA’s approval of Washington’s and Oregon’s 303(d) lists as arbitrary and capricious because the lists do not identify any coastal waters as impaired b y ocean acidification. ( See generally Compl.) The court previously denied the Western States Petroleum Association and American Petroleum Institute’s (collectively, “API”) motion to intervene, but granted API amicus curiae status. ( See 2/18/14 Order (D kt. # 22).) Later, the court also granted amicus curiae status to the Ecology Department of the State of Washington (“Ecology”), the Pacific Coast Federation of Fishermen’s Association, Southern California Trawlers’
Association and Institute of Fisheries Resources (collectively, “Fish ing Associations”),
and climate Ken Caldeira and Jane Lubchenco (collectively, “ the Scientists”). (Dkt.

material fact. Celotex , 477 U.S. at 323. If the moving party does not bear the ultimate burden of persuasion at trial, it can
show the absence of an issue of material fact in two ways: (1) by produc ing evidence negating an essential element of the non moving party’s case, or (2) by showing that the nonmoving party lacks evidence of an essential element of its claim or defense. Nissan

non moving party to identify specific facts from which a factfinder could reasonably find in the nonmoving party’s favor. Celotex , 477 U.S. at 324; Anderson v. Liberty Lobby,

B. Standing Before reaching t he merits of the action, the court addresses CBD’s standing to bring this challenge . API raises the issue of Article III standing in its amicus curiae brief 5 ( API Br. (Dkt. # 44)), and even if it did not, the court has “ an independent duty to assure that standing exists, irrespective of whether the parties challenge it.” Washington Envtl.
Council v. Bellon , 732 F.3d 1131, 1139 (9th Cir. 2013) (citing Summers v. Earth Island
Inst. , 555 U.S. 488, 499 (2009)). A plaintiff m ust demonstrate standing for each claim that he or she seeks to press and for each form of relief sought. DaimlerChrysler Corp. v. Cuno, 547 U.S. 332, 352 (2006). A plaintiff also bears the burden of proof to establish standing “with the manner and degre e of evidence required at the successive stages of the litigation.” Lujan v. Defenders of Wildlife, 504 U.S. 555, 561 (1992). At the summary judgment stage , a

5 As a preliminary matter, the court addresses API’s motion to file a reply brief on the issue of standing. (API Mot. for Reply (Dkt. # 58).) In granting amicus curiae status, the court cautioned that an amicus curiae “shall not file reply memoranda . . . unless authorized in advance by the court.” (2/18/14 Order at 21 (citing Federal Rule of Appellate Procedure 29(f).) Because the Western District of Washington’s Local Rules do not address the situation of amicus curiae, the court looked to the Federal Rules of Appellate Procedure for guidance. ( See id. ) The Federal Rules of Appellate Procedure permit amicus reply briefs with court permission. See Fed. R. App. P. 29(f). The court is aware that the Ninth Circuit’s Circuit Rule 29

- 1 disallows amicus reply briefs at the federal appellate level. Nonetheless, the court concludes that a reply brief is warranted here. First, API is the only entity to contest the issue of standing in this litigation. As such, its input on the issue will be of use to the court. Second, standing is a critical jurisdictional requirement that should be resolved on a full record and thorough briefing. Finally, CBD will not be prejudiced by the reply brief because CBD has taken full advantage of the two opportunities it was a fforded show standing, first in its opening motion and then in its combined response and reply (CBD Resp. (Dkt. # 57)). For these reasons, the court GRANTS API’s motion to file its proposed reply brief (API Reply (Dkt. # 58

- 11 plaintiff cannot rest on mere allegations, “but must set forth by affidavit or other evidence

s pecific facts, which for purposes of the summary judgment motion will be taken to be
true.” Bellon , 732 F.3d at 1139 (quoting Lujan , 504 U.S. at 561)

. Where, as here, the plaintiff is an organization, it may assert standing on behalf of
its members as l ong as the “members would otherwise have standing to sue in their own right, the interests at stake are germane to the organization’s purpose, and neither the claim asserted nor the relief requested requires the participation of individual members in the lawsuit.” F riends of the Earth, Inc. v. Laidlaw Envtl. Servs., Inc. , 528 U.S. 167, 181 (2000); see also Bellon , 732 F.3d at 1139 . The court finds that CBD meets the last two criteria, which API does not challenge. 6 As such, the crux of the standi ng inquiry is the
f irst criterion : whether CBD’s members would otherwise have standing to sue in their own right. An individual has Article III standing to sue if (1) he or she suffered an injury in fact that is concrete, particularized, and actual or imminent; (2) the inj ury is fairly traceable to the challenged conduct; and (3) the injury is likely to be redressed by a
favorable court decision. Bellon , 732 F.3d at 1139

- 2); Weitzer Decl. (Dkt. # 33

- 3); Moritz Decl. (Dkt. # 3 3

- 5).) These members rely on CBD to represent their interests in protecting marine species from threats like ocean acidification. ( See, e.g. , Antoine Decl. ¶ 5; Weitzer Decl. ¶ 5.) Accordingly, the interests at stake in this litigation are germane to CBD’s purpose. Moreover, the participation of individual members in the lawsuit is not required.

Def. Council v. EPA , 526 F.3d 591, 601 (9th Cir. 2008) (stating that an environmental plaintiff can satisfy the injury requirement by showing that the challenged activi ty impairs his or her “aesthetic and environmental well

— if the area in q uestion remains or becomes environmentally degraded. ” Ecological Rights Found ., 230 F.3d at 1149. Case 2:13-cv-01866-JLR Document 69 Filed 03/02/15 Page 12 of 701

CBD submits declarations from several of its members attesting to specific aesthetic and recreational injuries they are suffering or will suffer due to ocean acidification. Specifically, Jessica Antoine regularly visits the beaches in Netarts Bay, Pacific City, and Oswald West State Park in Oregon to go tidepooling, clamming, and purchase oysters, and is concerned that her ability to harvest cla ms and ot her shellfish and explore tidepools with her family will decrease due to ocean acidification.

David Weitzer visits the Washington and Oregon coastlines, including Willapa Bay in Washington and Gearhart, Seaside, Indian Beach, Canon Beach, Hug Point, Arch Cape, Falcon Cove, and Manzanita in Oregon, on average six times per year in order to dig for butter, steamer, and razor clams ; harvest o ysters, mussels, and barnacles; su rf ; and investigate tidepools to observe hermit crabs, small fish, chitons, starfish, anenomes,
urchins , and other organisms. (Weitzer Decl. ¶¶ 6

- 15.) Over the last 10 years he has
noticed that there are fewer and fewer oysters and cla ms available to har vest, the quality of the oyster shells has declined (they are now more brittle), the number and diversity of species in the tidepools has declined, and the number of shells washed ashore is reduced. ( Id. ) He is concerned that ocean acidification is respo nsible for these changes. ( Id. )
Anna Moritz regularly visits Puget Sound, including Golden Gardens Park,
Richmond Beach, and Whidbey Island, as well as the coasts of Washington and Oregon, including Fort Stevens State Park, Nehalem Bay, Manzanita, and Westport, to go tidepooling and beachcombing with her family. (Moritz Decl. ¶¶ 5

( Id. ) She is concerned that if the region’s coastal wa ters continue to increase in acidification, fewer shelled animals will survive, limiting her and her family’s opportunities for and enjoyment in finding shells, sea stars, sand dollars, and tidepool creatures during their trips to Puget Sound and the Washi ngton coast. ( Id. ) Katherine Easton owns a house on the water on Camano Island, in Puget Sound, which she visits almost every weekend during the summer, fall, and spring to walk through the extensive tideflats by her house and examine crabs, clams, and other creatures.

a. Washington Environmental Council v. Bellon API argues that Washington Environmental Council v. Bellon , 732 F.3d 1131, 1139 (9th Cir. 2013) precludes CBD from establishing that the EPA’s approval of the 303(d) lists caused its members’ injuries and that a favorable ruling would redress those injuries. ( See API Br.) In Bellon , the Ninth Circuit held that plaintiffs alleging aesthetic and recreational injuries linked to climate change in Washington did not have standing to challenge EPA’s approval of Washington’s decision not to regulate the greenhouse gas emissions of the state’s five local oil refineries under the Clean Air Act

. See id. at 1136

- 43. The C ourt reasoned that, because climate change was the cumulative result of greenhouse gas emissions from numerous independent sources intermingling on a global scale, the plaintiffs were unable to show that their localized injuries were either fairly traceable to or redressable by EPA’s failure to require greenhouse gas emission limits on
the local oil refineries. Id. at 1143

- 44; but see Massachusetts v. EPA , 549 U.S. at 524; Covington v. Jefferson Cnty. , 35 8 F.3d 626, 654 (9th Cir. 2004) (Gould, J., concurring) ; Washington Envtl. Council v. Bellon , 741 F.3d 1075, 1080 (9th Cir. 2014) (Gould, J. , dissenting from denial of rehearing en banc).

Spawning & Recovery Alliance v. Gutierrez , 545 F.3d 1220, 1226 (9th Cir. 2008). This lower standard does not apply to CBD because CBD does not assert a procedural right in this action. The Clean Wate r Act’s citizen suit provision, which applies to nondiscretionary duties by EPA, is inapplicable to CBD’s challenge. ( See Compl . ¶ 9); 5 U.S.C. § 706(2)(a); 33 U.S.C. § 1365(a); Natural Res. Def. Council , 542 F.3d at 1245. Furthermore, CBD does not alleg e that EPA failed to adhere to any procedure mandated by statute or regulation. Rather, CBD challenges EPA’s substantive decision to approve two 303(d) lists excluding waters allegedly impaired by ocean acidification. See City of Dover v. EPA , No. CV 12

- 1994(JDB), 2014 WL 1410399, at *8 (D.D.C. Apr. 14, 2014) (finding that challenge to EPA’s approval of New Hampshire’s 303(d) list did not allege violation of a procedural right); see generally Massachusetts , 549 U.S. at 517

The parties here agree that oceanic uptake of atmospheric, anthrop ogenic carbon is the primary driver of ocean acidification on a global scale. ( See CBD Resp. at 16; API Br. at 7); see also Feeley 2012 at 9 . API reasons that, because CBD cannot point to a mechanism under the Clean Water Act that addresses global carbon emissions in an appreciable way, and because the record lacks evidence regarding the effect of local
carbon emissions on local ocean acidifi cation, Bellon precludes CBD from showing causation and redressability. ( See API Br. at 9

- 11.) CBD, however, bases its causation and redressability arguments on a different premise. CBD contends that regional human

- caused drivers exacerbate ocean
acidifi cation along Washington ’s and Oregon’s coasts, and that local pollution controls can reduce the input from these drivers. ( See, e.g. , CBD Mot. at 1 5.) CBD maintains that, if its suit to add acidified

- impaired waters to the states’ 303(d) lists is success ful, these local measures could be employed to implement the applicable TMDLs, thereby alleviating its members’ injuries. ( See CBD Resp. at 14.); see also 33 U.S.C. § 1313(e);
Pronsolin o , 291 F.3d at 1128. Framed as such, causation and redressability ar e t wo sides of the same coin:
CBD’ s members’ injuries are traceable to EPA’s conduct and redressable by a favorable ruling to the extent that coastal waters improperly not identified as acidified

- impaired are influenced by sources that can be mitigated by local actions. Accordingly , the court
addresses the se two standing elements together in the following sections

b. CBD’s evidence CBD relies on several scientific studies in the administrative record, as well as the 2012 report by the Washington State Blue Ribbon Panel on Ocean Acidification, 9 and a declaration by Dr. Burke Hales, Professor of Oregon Ecology and Biogeochemistry at Oregon State University (Hales Decl. (Dkt. # 57

- 1)) to establish causation and redressability. This evidence shows that “a lthough atmospheric CO2 is the major driver of acidification globally, near the coasts

— particularly highly populated or developed

areas

— other drivers that generate additional CO 2 in the water column also contribute significantly to acidification.” Feeley 2012 at 9. In particular, “acidification in Washington State coastal waters is driven by a combination of factors, particularly in the deep waters of Puget Sound and the nearshore regions.” Id. at 13. Similarly, regional
drivers also affect the acidific ation of Oregon’s coastal waters. Id. at 9

- 15.
CBD identifies the following regional drivers that influence Pacific Northwest coastal waters. First, the “near

- surface coastal waters off Washington and Oregon” are unusually susceptible to conditions of respiration and hypoxia (low oxygen levels) , which are caused by algae growth stimulated by excessive nutrients. Feeley 2012 at 12 . These
process es are “acknowledged to be important drivers of ocean acidification, particularly when the land nearby is hig hly populated or agriculturally developed.” Id. In such areas, “human activity increases the amount of nutrients such as nitrate, phosphate, and iron

9 The Washington State Blue Ribbon Panel on Ocean Acidification (“Blue Ribbon Panel”), which included scientists, industry representatives, and state, local, and federal policy makers, was convened under the auspices of the National Oceanic and Atmospheric Administration’s National Shellfish Initiative to develop recommendations to respond to ocean acidification and reduce its harmful causes and effects in Washington.

Panel at 43. For example, human sources of nitrogen in Puget Sound have increased steadily to the point where they form a “considerable contribution” to nitrate levels that
exceed n atural conditions. Feeley 2012 at 29, 33. “In particular, Hood Canal, South Puget Sound, and other shallow, enclosed bays and estuaries are particularly susceptible to periodic, sometimes catastrophic low oxygen levels that can lead to fish kills and oth er biological impacts.” 10 Blue Ribbon Panel at 44.

Within Puget Sound, circulation is sluggish in many of the restricted inlets of Hood Canal and South Sound so that terrestrial inputs may have relatively localized impacts. For instanc e, localized inputs of nitrogenous nutrients, such as are associated with development and urbanization, have been observed to stimulate enhanced primary production in surface waters in certain parts of Puget Sound with restricted circulation and developin g shorelines.” Feeley 2010 at 443 (internal citations omitted).

In addition, CBD’s evidence shows that “ Washington’s marine waters are particularly vulnerable to ocean acidification because of regional factors that exacerbate the acidifying effects of global carbon dioxide emissions.” Blue Ribbon Panel at xii; see also Feeley 2012 at xi (“Washington State is particularly vulnerable because of its location and regional oceanography.”) One of the most important natural regional factors is coastal upwelling.

11 EPA moves to strike Dr. Hales’ declaration for two reasons. First, EPA complains that Mr. Hales’ declaration is not a part of the administrative record. Dr. Hales’ declaration, however, was submitted for the limited purpose of satisfying Article III standing requirements. ( See CBD Resp. at 16

- 19.) The court does not rely on this declaration to judge the merits of CBD’s claims against EPA. EPA cites to no authority requiring that stand ing be established on the administrative record, and, to the extent that is EPA’s position, EPA fails to explain why it challenged Mr. Hales’ standing declaration but not CBD’s members’ declarations. Both the Ninth Circuit and the Supreme Court have relie d on scientists’ declarations when evaluating standing in environmental cases. See, e.g. , Bellon , 732 F.3d at 1143 (“Thus, according to the unchallenged declaration of [intervenor’s] expert . . . .”); Massachusetts , 549 U.S. at 522 (quoting declaration fr om a climate scientist); see also Barnum Timber Co. v. EPA , 835 F. Supp. 2d 773, 778 (N.D. Cal. 2011) (relying on extra

- record expert declarations to find standing). Therefore, the court finds that EPA’s motion to strike on that ground is not well

- taken. Second, EPA complains that the declaration was included with CBD’s combined response and reply brief, rather than with CBD’s original motion for summary judgment. ( See EPA Reply (Dkt. # 59).) A court should not consider new evidence submitted in a reply brief without giving the opposing party an opportunity to respond. Provenz v. Miller , 102 F.3d 1478, 1483 (9th Cir. 1996) . Based on the parties’ stipulated modified briefing schedule, however, the court is unconvinced that it is appropriate to view Dr. Hales’ declaration as submitted in a reply brief. The accompanying brief is a combined response to EPA’s cross motion for summary judgment, reply to EPA’s response to CBD’s motion for summary judgment, and response to the amicus briefs filed in support of EPA, which were filed after CBD’s original motion. ( See Sched. Order.) The challenge to CBD’s standing was not raised until amicus briefs were filed. ( See API Br.) More importantly, EPA had the opportunity to address Dr. Hales’ declaration in its own reply brief, which was due after CBD’s combined response and reply. ( See id. ) EPA chose not to address the evidence substantively, but rather moved to strike it. ( See EPA Reply at 19.) Additionally, API, the only entity that has raised the issue of sta nding, has been granted a full opportunity to respond to the declaration. ( See API Reply (Dkt. # 58

- 1).) API concedes that Dr. Hales’ declaration “generally states what has already been stated in the record.” ( Id. at 7.) For these reasons, the court de nies EPA’s motion to strike Dr. Hales’ declaration. Case 2:13-cv-01866-JLR Document 69 Filed 03/02/15 Page 22 of 701

Ribbon Panel cautioned: We should not put nutrient control efforts on hold while this scientific work is done, however. On the contrary, the Panel recommends that existing nutrient and organic carbon reduction programs be enhanced and strengthened; these pollutants are already lowering dissolved oxygen levels and causing a variety of significant ecosystem impacts in some areas.

c. API’s arguments API argues that CBD’s evidence is insufficient to show causation and redressability for two reasons, neither of which are persuasive. First, API contends that CBD has not shown standing because the relative contributions of global and regional anthropogenic sources to local ocean acidification remain unclear, and therefore it is
uncertain that reductions by local mitigation techniques will be sufficient to ameliorate
harm to shellfish and other marine animals. (API Br. at 17; API Reply at 7 ); see , e.g. , Feeley 2012 at 9 (“These inputs and their relative importance will vary with space and Case 2:13-cv-01866-JLR Document 69 Filed 03/02/15 Page 24 of 701

To the contrary: “That a first step might be tentative does not by itself support the notion that federal courts lack jurisdiction to determine whether that step conforms to law.” Id. This principle rings especially true here, where CBD has put forth evidence that the waters of the Pacific Northwest are naturally poised near a tipping point, such that the even a small increment of acidity can have dramatic biological consequences.

Massachusetts , 549 U.S. at 525. Because CBD’s evidence shows that local driver s of
ocean acidification can have disproportionate and biologically significant effects on local Pacific Northwest waters, standing is established

Second, API contends that CBD has not shown standing because CBD has not identified which specific local mi tigation techniques are applicable to the beaches identified in its members’ declarations. (API Br. at 18; API Reply at 7.) CBD, however, has shown that a range of human causes contribute to ocean acidification in the coastal regions its members visit, w hich causes are significant in each region, and which mitigation or remediation techniques are applicable to each cause.

Ninth Circuit confirmed an env ironmental organization’s standing to challenge the EPA’s

So, too, here. The relief CBD seeks

. . . is fairly traceable to the EPA’ s failure to review [Florida’s] Impaired Waters Rule, since use of the Rule could result in polluted waterbodies being
left off the Impaired Waters List and not being cleaned. ”) For this reason, also, the court
finds that CBD has shown causation and redressability.
3. Summary Because CBD has set forth “specific facts” establishing injury in fact, causation, and redressability, as well as the remaining prerequisites for organizational standing, CBD’s claims are properly before the court. See Bellon , 732 F.3d at 1139.
C. Merits Having found standing, the court turns to the merits of CBD’s claims. CBD raises two arguments: (1) EPA’s explanation for its de cision to approve Washington ’s and Oregon’s Section 303(d) lists runs counter to the evidence before the agency and is implausible in light of that evidence, and (2) Washington and Oregon failed to consider all existing and readily available water quality data when creating their impaired waters
lists . The court reviews both of these challenges under the arbitrary and capricious
standard.
1. Arbitrary and Capricious Standard EPA’s decision to approve the 303(d ) lists is reviewable under the Administr ative
P rocedures Act (“APA”). 5 U.S.C. § 706(2)(A); Dioxin/Organochlorine Ctr. v. Clarke , 57 F.3d 1517, 1521 (9th Cir. 1995); Envtl. Def. Fund, Inc. v. Costle , 657 F.2d 275, 283 (1981).

Ass’n v. State

The court is grateful for the amici’s involvement in the case and willingness to educate the court on the topic of ocean acidification. Nonetheless, the court concludes that it must strike this evidence for the following reasons. First, to the extent the references explain the basic scientific concepts and consequences associated with ocean acidification, they are c umulative of the extensive
admi nistrative record already before the court. See Northcoast Envtl. Ctr. v. Glickman , 136 F.3d 660, 665 (9th Cir. 1998) (upholding district court’s decision to “ strike cumulative and unnecessary documents ou tside the administrative record”); ( see, e.g. , Scientists Br. at 1 n.2 (citing NOAA, PMEL Carbon Program, What is Oc ean Acidification? to explain the basics of ocean acidification ) .) Second, as amici concede, most of the references post

. See WA Approval; OR Approval; ( Fishi ng Resp. at 9; Scientist Br. at 10 n.27 ; Mot. to Strike 1 at 5 n.4 .) Although post

( See, e.g. , Scientist s Br. at 18 (arguing that EPA should have listed Willapa Bay as impaired because a 2013 article “conclusively linked” oyster deaths at a local hatchery to ocean acidification and a 2014 article stated that wild oysters in the bay were unable to reproduce successfully).) 14

Therefore, this evidence is admissible for the purpose of determining whether EPA considered all relevant factors before approving Washington’s 303(d) list. See Inland Empire Pub. Lands Council v. U.S. Forest Serv. , 88 F.3d 754, 760 n.5 (9th Cir. 1996) (“To the extent [the extra

the se data sets show repeated violations of Washington’s numerical pH water quality standard that compel EPA to include numerous waters on Washington’s 303(d) list. (CBD Resp. at 13, n.16, n.17; Fishing Br. at 10

3. Evidence before the agency CBD ’s first argument is that the evidence before EPA at the time of EPA’s decision to approve Washington’s and Oregon’s 303(d) lists showed violations of Washington’s numerical pH standard, as well as violations of Washington’s and Oregon’s narrative standards regarding aquatic l ife. The court addresses each contention
in turn below.

17 The court considers this data, with one exception. The court strikes CBD’s reference to the “NANOOS” data (CBD Resp. at 10 n.17) bec ause CBD cites only data from 2014 and earlier data is not publicly available. See Sw. Ctr. for Biological Diversity , 100 F.3d at 1450

Ecology evaluated the Wootton study and data and co ncluded that the data did not show impairment of Washington waters because (1) the study did not provide conclusive evidence that the pH change was due to human sources rather than natural inputs, (2) the monitoring site is located within the Makah Indian reservation and therefore outside Ecology’s regulatory authority, and (3) the characteristics of the single sampling location are unique and therefore the data could not be extrapolated to adjacent waters.

In addition, Ecology now points out that Washington’s numerical pH standard refers to a change of 0.2 pH units per year , and , as such, the study’s evidenced change of 0.046 units per year does not violate the standard. (Ecology Br. at 12.) When reviewing Washington’s 303(d) list, EPA undertook an independent evaluation of the Wootton study and data and concluded that, “for a variety of reasons, including the unique sampling location in the study, information from [the Wootton]
documents was insuf

ficient to determine the attain ment status of Washington’s marine pH criteria.” WA

Kilduff “ used the Wootton_ 2009 Hydrolab Data Filtered.xls from the Administrative Record # WA

000731 to generate the graphs and summary tables.” (Kilduff Decl. ¶ 4.) It should go without saying that the co urt is not capable of interpreting the raw data on its own. Without Dr. Kilduff’s explanation, the court would not have been able to evaluate the data as a basis for CBD’s challenge separate and distinct from the Wootton article. Because Dr. Kilduff’s de claration is merely explanatory of the original record before EPA, it is admissible. See Bunker Hill Co. , 572 F.2d at 1292.

First, EPA, relying on the analysis of C heryl Brown of EPA’s Pacific Coastal Ecology Branch in the Office of Research and Development, concluded that Wootton does not establish that the observed pH changes were human

- caused. Specifically, Wootton’s model did not take into consideration natural processes, such as river discharge effects. WA

- 00133 8 (“Brown 2012”); WA

reflected local, na t ural conditions rather than large

- scale anthropogenic pH declines

across ocean waters. 20 See Brown 2012 at 8

- 15, 20

not conclusively establish that the observed p H changes were human

20 In addition, EPA relied on Feeley 2010, which concluded that the decline in pH at Tatoosh Island was “probably explained by a c ombination of factors, including enhanced upwelling of waters of the Washington coast resulting from changes in regional ocean circulation.” Feeley 2010 at 18; see also WA

Second, e ven if the Wootton study did prove violations of Washington’s numerical pH standard, EPA was justified in determining that the study’s results did not require listing adjacent waters, such as the Strait of Juan de Fuca. States do not have jurisdiction
over tribal waters su ch as Tatoosh Island. 22 See WA

- 001304

- 05. Dr. Brown concluded
that the results from Tatoosh Island were not indicative of ocean trends in nearby waters because “[t]he oceanography in this region is influenced by numerous physical factors including complex bathymetry, upwelling . . . and the presence of large

- scale eddies and multiple river plumes.” Brown 2012 at 2. EPA agreed with Ecology that these factors “make the Tatoosh Island sampling location highly unique,” and therefore

That guidance is inapposite to numerical standards, such as Washing ton’s pH standard, that define only anthropogenic variances as excursions. The court has struck as improper post

- decision evidence the Scientists’ references to and reliance on EPA’s 2014 Guidance regarding “natural conditions” provisions. See supra Sec tion III.C.2; but see EPA 2014 Guidance (stating that EPA’s position on “natural conditions” provisions has remained unchanged since EPA’s 2006 and 2008 guidance letters, which are located in the administrative record at WA

- 1170 and WA

- 01149, respectively) . If the court had not stricken this line of argument, the Scientists’ reliance on EPA’s 2014 guidance regarding “natural conditions” provisions would be similarly misplaced. ( See Scientists’ Brief at 4

- 5 (citing Information Concerning 2014 Clean Water A ct Sections 303(d) (Sept. 3 , 2013) (“ If the pollutant concentrations do not meet the EPA

- approved water quality standards, and anthropogenic sources of the pollutant are present, the water is considered impaired and should be included on the State’s Sectio n 303(d) list even if natural sources of the pollutant are present.”).) “Natural conditions” provisions permit standards to be adjusted to account for natural conditions that cause violations. See WAC 173

shellfish decline; laboratory studies; hatchery studies; and data regarding aragonite saturation. ( See CBD Mot.) For its part, EPA contends that a finding of impairm ent is unwarranted because (1) the record lacks in situ field studies or other documentation showing adverse effects on indigenous aquatic life populations in either state attributable to stressors caused by ocean acidification, and (2) the other evidence relied on by CBD in place of such studies is Case 2:13-cv-01866-JLR Document 69 Filed 03/02/15 Page 43 of 701

- 71. Th e Barton study found that larval production and growth at Whiskey Creek Hatchery was negatively correlated with the aragonite saturation state of the bay water in which the oysters were spawned and reared
for the first 48 hours of life. See Barton 2012 at 705; Feeley 2012 at 71

. To begin, the court finds that EPA rationally determined that the Barton study, which considered only circumstances specific to Netarts Bay, could not be extrapolated to require listing of distant or dissimilar Washington and Ore gon waters. EPA found that the natural variability of surface ocean carbonate chemistry influences how ocean acidification impacts shellfish from region to region, and that Netarts Bay therefore could not serve as a proxy for other coastal waters. See OR 2

- 88 (citing Freidrich 2012); Barton 2012 at 699

- 700, 703 (describing the two majors forcing driving Netarts Bay’s carbon chemistry fluctuations: upwelling and metabolic variability). EPA identified differences between Netarts Bay and other Pacifi c Northwest waters and concluded: “All of these variables make the extrapolation of data across a large geographical range for the purposes of determining non

- attainment of water quality standards in local water bodies difficult and inappropriate in these circumstances.” OR2

- 000287. As EPA noted, the Barton study cautioned that “two significant shortcomings exist with regard to understanding acidification effects on natural populations of organisms in variable coastal and estuarine habitats: prediction o f how carbonate conditions will vary in coastal and estuarine environments with increasing atmospheric
CO 2 and a better understanding of the fundamental biology underlying the responses of multicellular organisms to acidification.” Barton 2012 at 709; see OR2

F.3d at 1076

. A closer question is whether it was arbitrary and capricious for EPA to approve Oregon’s 303(d) list that did not include Netarts Bay as impaired. To begin, EPA’s contention that Oregon’s narrative standards were not violated because the seawater measured in Netarts Bay did not violate Oregon’s numerical pH standard (EPA Mot. at 21) is misguided . The Supreme Court has made clear t hat waters are impaired if they fail
to meet either narrative standards or numerical criteria. PUD No. 1 of Jefferson Cnty. v. Washington Dep't of Ecology , 511 U.S. 700, 715

- 16 (1994). Nonetheless, the court concludes that, taking into account the defere nce due to EPA’s technical expertise, EPA has articulated a “satisfactory explanation” for its conclusion that the hatchery shellfish die

- offs did not require listing Netarts Bay as impaired. See Humane Soc ’y of U.S. v. Locke , 626 F.3d 1040, 1048 (9th Cir . 2010); League Of Wilderness Defenders Blue Mountains Biodiversity Project , 615 F.3d at 1130.
EPA based its decision on the fact that the Barton study did not present any data or information “demonstrating impaired health of wild, natural populations in O regon waters.” OR

- 000289. CBD maintains that EPA’s focus on “wild” and “natural” populations was improper because the Oregon water quality standards do not explicitly contain such restrictions. (CBD Mot. at 22

The court finds that in the absence of a statutory definition of “resident biological communities” or similar guidance from the State of Oregon, EPA’s interpretation of the standards is not arbitrary and capricious. The mere fact that the Whiskey Creek oysters are grow n in tanks filled with water drawn from Netarts Bay does not make them “residents” of the Bay in the ordinary sense of the word. See Barton 2012 at 700 (explaining Whiskey Creek Hatchery’s process of raising oysters in tanks ). Beyond that, EPA shows a rational connection between the evidence available at the time of the listing decision and its conclusion that the Barton study does not show
deleterious effects on w ild shellfish populations. See Motor Vehicle Mfr. Ass’n , 463 U.S.
at 44. The study observed a correlation between saturation state and oyster growth, but at least according to the record before EPA at the time of the listing decision, it remained
unclear whether saturation state was responsible for the large

v. Summary The amici Scientists contend that EPA improperly focused on the deficiencies of each piece of evidence in isolation and therefore failed to recognize the cumulative import of the evidence. (Scientists Br. at 20.) As discussed above, however, EPA’s
scientific asses sment of the applicability of each category of evidence to the problem at
hand , was not implausible or contrary to the evidence

. Those assessments remain valid whether viewed together or in isolation, because no category of evidence solves the problems id entified with the other categories of evidence . In this context, the whole is not greater than the sum of its parts. Moreover, the Scientists cannot avoid the fact that the record evinces no
documentation of adverse effects on wild aquatic life populati ons in Washington or Oregon attributable to ocean acidification. See WA

For all of these reasons, the court finds that EPA’s approval of Washington ’s and Oregon’s impaired waters lists was neither implausible nor contrary to the evidence.
4. Existing and readily available water quality data CBD ’s second argument, echoed by the Fishing Associations is that Washington and Oregon improperly ignored certain marine pH data, and therefore EPA’s approval of Washington’s and Oregon’s lists without independently evaluating data from these sources was arbitrary and capricious. (CBD Mot. at 29

If a state decides not to rely on certain existing and readily available data or information, the state must provide EPA with docume ntation explaining the rationale for that decision. 40 CFR 130.7(b)(6). 26 If a state fails to assemble and evaluate all existing and readily available data, EPA may not approve the state’s 303(d) list until EPA undertakes its own evaluation of the overloo ked data. 40 CFR 130.7(d)(2); see also OR Disapproval (partially disapproving Oregon’s 2010 303(d) list for failure to evaluate certain water quality data); OR Approval (identifying impaired waters from the overlooked water quality data).

26 Each state must also provide EPA documentation showing (1) a description of the methodology used to develop its 303(d) list, (2) a description of the data and information used to identify listed waters, and (3) any other reasonable information requested by EPA. 40 CFR 130.7(b)(6).

EPA concluded that Washington and Oregon complied with all statutory and regulatory requirements in deciding that their state waters did not exhibit impairments
associated with ocean acidification. See WA Approval; OR Approval. CBD and the Fishing Associations , howeve r, identify four data sources that they conten d the states improperly ignored, namely, Ecology’s own long

- term marine monitoring database, the USGS database, the STORET database, and the NOAA database. ( See generally CBD Mot.; Fishing Mot.) The court add resses each state ’s decision in tu r n below

.

a. Oregon’s list The Oregon administrative record contains a spreadsheet of pH data that Oregon considered when making its listing decision. See OR2

- 000480 . CBD and the Fishing Associations have identified no additional pH monitoring datasets from Oregon waters. ( See generally CBD Mot.; CBD Resp.; Fishing Mot.) And they have provided no explanation as to why monitoring datasets from Washington’s coastal w aters would be relevant to Oregon’s listing decision. As such, the court has no basis on which to judge CBD’s challenge to EPA’s approval of Oregon’s 303(d) list for failure to consider all existing and readily available water quality data. Therefore, CB D’s challenge with respect to Oregon’s 303(d) list fails.

b. Washington’s list The Washington administrative record does not contain any marine pH data that Washington considered when making its listing decision. See generally Administrative
Record. CBD a nd the Fishing Associations claim that Ecology improperly failed to

- term marine water quality data , Marine Water Monitoring, http://www.ecy.wa.gov/apps/eap/marinewq/mwdataset.asp (last visited February 3, 2015). CBD and the Fishing Associations present evidence suggesting that these
measurements show r epeated water quality violations of Washington’s numerical pH standard in Puget Sound, Gray’s Harbor, and Willapa Bay. (Fishing Br . at 10

- 000069 (Ecology response to CBD’s ocean
acidification comments ). Therefore, Ecology declined to rely on the data to make listing

Feeley & Alin) collected measurements of DIC [d issolved organic carbon] and total alkalinity to calculate pH changes in Puget Sound waters. Based on the

- 61 Ecology’s methodology was flawed, perfunctory, or otherwise inadequate. Moreover, Ecology applied its Water Quality Policy neutrally to the long

- term monitoring pH data: Ecology changed water segments to Category 3 regardless of their current status of attainment, non

- attainment, or waters of concern, and applied the change to segments that exhibited either, or both, low and high pH excursions. See, e.g. , WQA (discussing sampling locations at Port Townsend (PTH005), Gray’s Harbor (GYS004), Oakland Bay (OAK004), and Budd Inlet (BUD005)). Finally, EPA’s decision to accept Ecology’s
rationale was informed by its technical expertise and experience in a complex scientific

area and, as such, is entitled to great deference. See Envtl. Def. Ctr., Inc. , 344 F.3d at 869; League Of Wilderness Defenders Blue Mountains Biodiversity Project , 615 F.3d at

Sierra Club v. Leavitt does not suggest otherwise. See 488 F.3d at 912. In Sierra
Club , the Eleventh Circuit found that Florida’s bright line rule that excluded all water quality data older than 7.5 years violated the requirement to evaluate all existing and readily available data, and therefore EPA was requ ired to independently evaluate the reliability of the excluded data before approving Florida’s list.

- 65 (8th Cir. 2009) (deferring to EPA’s approval of the state’s finding that the monitoring data for certain water segments was insufficient because the plaintiffs “offer[ed] no explanation or support as to why additional data are required to conclude that the existing data are insufficient”). The remaining arguments raised by the Fishing Associations are unavailing. First, the Fishing Associations rely on extra

- record evidence to argue that the electrode probes used by Ecology are designed to be accurat e to 0.1 pH units, and therefore Ecology’s conclusion that the probes evidenced “large (+/

- 0.5 pH)” errors is suspicious. ( See Fishing Br. at 13

- 14.) Ordinarily, such extra

- record evidence is inadmissible to judge an agency’s decision. See Lands Counci l , 395 F.3d at 1030 . The Fishing Associations contend that this evidence is admissible as necessary to determine whether EPA
considered all of the relevant factors. See id. The court declines to decide the issue
because even if the evidence were admissi ble, it would have no bearing on the court’s
evaluation of EPA’s decision.

To begin, two of the documents are irrelevant to the Fishing Associations’ arguments. 29 The third document, an online specification sheet for the probes that Ecology uses to measure coastal pH, states that an accuracy of +/

- 0.1 pH unit is “achievable with frequent field calibrations.” 30 Yet the fact that the probes are designed to be accurate to 0.1 pH units does not contradict Ecology’s observation that the probes

we re functioning less than optimally in situ . The design specification , without more, does not cast doubt on Ecology’s analysis or EPA’s finding that Ecology’s analysis was
reasonable. Next, the Fi shing Associations contend that even after Ecology and E PA determined the data was unreliable, Ecology and EPA should have continued “evaluating” the data by making certain assumptions about the data. (Fishing Br. at 14

- 15.) Specifically, the Fishing Associations argue that, even assuming the +/

- 0.5 pH units error range operated only to under

- count pH excursions, and even conceding the +/

- 0.5

29 The document titled “Washington State Marine Water Quality, 1998

- 2000” at page 13 merely lists a series of “monitoring data quality objectives,” one of which is that the “reporting limit” for pH monitoring is 0.1 pH units. A reporting limit, however, refers to the lowest concentration of a chemical that an instrument can observe with any degree of co nfidence, not to the accuracy of the instrument. Moreover, this limit is an agency objective, not an instrument specification. Next, the document titled “Stream Sampling Protocols for the Environmental Monitoring and Trends Section, October 2001” sets fo rth the procedure for collecting pH stream measurements and mentions an “assumed” precision of 0.1 pH units. Precision, however, is not the same as accuracy: accuracy is the proximity of a measurement to the true value, whereas precision refers to the re peatability or reproducibility of a measurement. Moreover, it is unclear that freshwater sampling protocols are applicable to the coastal issues raised in this case. As such, neither of these documents is relevant to EPA’s decision. See Fed. R. Evid. 40 1, 402.

- 64 pH units error range rendered the data inadequate to assess Washington’s prohibition of anthropogenic changes greater than 0.2 pH units, the data can still be relied up on to show numerous violations of the 7.0 pH lower limit of Washington’s numerical pH standard. ( Id. at 14

- 15, Table 4 (tallying measurements below 6.5 pH at various sampling points).) Ecology, however, specifically found that the electrode probes’ inacc uracy was substantial and “non

- quantifiable.” See WA

- 000153. The court declines to require an agency to continue to rely on a dataset that the agency has already determined is inaccurate. Such a requirement would not only be bad law, it would be bad sci ence. Contrary to CBD and the Fishing Associations’ assertions, the court is not condoning a tactic of avoiding the responsibility to assemble and evaluate all existing data by knowingly conducting unreliable monitoring and then choosing to ignore the

re sults. ( See Fishing Br. at 13; CBD Resp. at 12.) The court does not comment on Ecology’s future responsibilities with respect to coastal pH data monitoring now that Ecology is aware of the unreliability of its current monitoring system. The court remain s unconvinced, however, that it is any kind of a solution to force continued reliance on

error
- prone data once an agency has recognized the error. For these reasons, the court finds that EPA did not act arbitrarily or capriciously in declining to conduct an independent evaluation of Ecology’s long

- term marine monitoring pH data.

EPA’s responsibilities with respect to the two lists, however, were not commensurate.

Moreover, not only did no party raise the issue of USGS and STORET pH marine data with EPA, but Ecology’s Water Quality Assessment spreadsheet shows that Ecology did rely on USGS and STORET pH data for many non

- marine waters. See, e.g. , WQA (entries for Palouse River, Columbia River, Ozette River, Soleduck River, Cedar Creek, and Paradise Creek, among others). Ecology’s Water Quality Assessment contains over 65,000 entries explaining the data considered for each pollutant within each Wa shington water segment. See generally id. Requiring EPA to sua sponte recognize and investigate
the absence of USGS and STORET marine pH data (as opposed to the other USGS and STORET data that Ecology indisputably considered) from these tens of thousands of entries would set an impracticably high bar. See Barnum Timber Co

. , 835 F. Supp. 2d at 781 ( emphasizing that the Clean Water Act gives EPA only 30 days to approve or disapprove a state’s impaired waters list) ; 33 U.S.C. § 1313(d)(2) (“ The Administrator shall either approve or disapprove such identification and load not later than thirty days after the date of submission.”).

Similarly, EPA’s 2010 memo randum on ocean acidification stated that NOAA’s National Estuarine Research System “may be useful to States as they assess coastal waters for marine pH impairment.” EPA OA Memo at 7.

Furthermore, CBD concedes that Ecology received and reviewed over 100 studies, articles, and letters regarding ocean acidification al one, not to mention the prodigious volume of the comments, data, and information the agency received regarding the remainder of the impaired waters list.

32 CBD also contends that EPA and Ecology improperly failed to obtain pH data from Dr. Feeley. (CBD Mot. at 34.) CBD, however, provides no evidence that a relevant pH dataset of Washingto n waters collected by Dr. Feeley exists, let alone a dataset that suggests violations of Washington’s pH standard.

c. Summary In sum, the court finds that EPA’s conclusion that Washington and Oregon satisfied the regulatory requirement to assemble and evaluate all readily available water quality data regarding ocean acidification was not arbitrary and capricious. As such, both of CBD’s challenges to Washington ’s and Oregon’s lists are unsuccessful. Because EPA’s approval of Washington ’s and Oregon’s Section 303(d) lists is plausible in light of
the evidence and EPA reasonably concluded that Washington and Oregon assembled an d
evaluated all existing and readily available water quality data, EPA is entitled to summary judgment in its favor. See Celotex Corp. , 477 U.S. at 322.
IV. CONCLUSION For the foregoing reasons, the court DENIES CBD’s motion for summary judgment (Dkt. # 33) and GRANTS EPA’s motion for summary judgment (Dkt. # 34). The court GRANTS IN PART and DENIES IN PART EPA’s motions to strike (Dkt.
