    On Appeal from the Board of Veterans' Appeals
    (Argued June 20, 2018                                                          Decided September 19, 2018)

    Before DAVIS, Chief Judge, and PIETSCH and ALLEN, Judges.
    ALLEN, Judge: In Gray v. McDonald, 1 this Court held that VA's interpretation of 38
    C.F.R. § 3.307(a)(6)(iii) designating Da Nang Harbor as an offshore waterway, while designating
    other bays and harbors as inland waterways, was arbitrary and capricious.2 The Court remanded
    the matter for VA to reevaluate its waterway definitions in light of the purpose of the regulation—
    to provide compensation based on the probability of herbicide exposure.3 In February 2016, VA
    modified its definition of "inland waterways" in its Adjudications Procedures Manual (M21-1),4
    opting not to adopt a formal regulation in title 38 of the Code of Federal Regulations and, thereby,
    obviating the requirement for notice-and-comment under the Administrative Procedure Act
    (APA).5 The new M21-1 provision excluded all Vietnamese bays and harbors from the definition

    of "inland waterways."6 In June 2017, the Federal Circuit decided DAV v. Secretary of Veterans
    Affairs, in which it held that the M21-1 is an internal manual used to guide VA adjudicators and
    does not establish substantive rules.7 The Federal Circuit specifically noted that the Board is not
    bound by the M21-1.8
    Before us today is U.S. Navy veteran Patrick M. Overton who served on active duty from
    March 1967 to February 1968, including service aboard the U.S.S. Providence while it operated
    and anchored in Da Nang Harbor from October to December 1967. He appeals a November 1,
    2016, Board of Veterans' Appeals decision that denied service connection for type II diabetes
    mellitus with retinopathy and ischemic heart disease, both including as due to herbicide exposure.9
    The Board concluded that the appellant had not demonstrated actual exposure to herbicides and
    also that he was not entitled to the presumption of exposure.10 The Board relied on the modified
    M21-1 provision to deny the appellant's claims concerning presumptive herbicide exposure.11 Yet,
    the Board did not discuss why it relied on the M21-1. The appeal is timely, and the Court has
    jurisdiction to review the Board's November 2016 decision.12 This matter was referred to a panel
    of the Court primarily to address the Board's reliance on VA's new M21-1 provision. The Court
    will also address the basis for its reasoning in Gray.
    As we explain below, the Court holds that when relying on any M21-1 provision, the Board
    must independently review the matter the M21-1 addresses. If after such review, the Board chooses
    to rely on the M21-1 as a factor in its analysis or as the rule of decision, it must provide adequate
    reasons or bases for doing so. The Board may not simply rely on the nonbinding M21-1 position
    without analysis. Because the Board did not engage in the appropriate analysis here, the Court will
    set aside the November 1, 2016, Board decision and remand the matter for readjudication
    consistent with this decision. Given this disposition, the Court declines to opine on the content of

    the decision concerning direct exposure because the Board's analysis may be affected by the
    actions it takes on remand concerning presumptive exposure.
    I. FACTS AND PROCEDURAL HISTORY
    This matter stems from the appellant's timely Substantive Appeal of a May 2013 VA
    regional office denial of his claims for benefits for type II diabetes, diabetic retinopathy secondary
    to diabetes, and ischemic heart disease.13
    In January 2016, the appellant's private physician, Chris Martin, M.D., opined that the
    appellant's diabetes may have been caused by exposure to herbicides.14 The appellant submitted a
    statement to VA explaining that he had experienced headaches while he was aboard the U.S.S.
    Providence, he reported odd smells, and observed that his headaches lessened in intensity when
    the ship departed Da Nang Harbor.15 In March 2016, another private physician, Michael Sokol,
    M.D., opined that it is at least as likely as not that the appellant was exposed to Agent Orange,
    which accounts for his development of type 2 diabetes.16 He noted that the appellant did not have
    any genetic predisposition to diabetes, which makes it more likely that his exposure to Agent
    Orange "is the likely precipitant" to that condition.17 Dr. Martin's and Dr. Sokol's opinions are the
    only etiological medical evidence of record.
    In November 2016, the Board issued the decision on appeal denying the appellant's claims.
    The Board reviewed the appellant's lay statements that he had been exposed to herbicides while
    aboard the U.S.S. Providence to provide support for combat troops. The Board generally explained
    that because "inland waterways" are not defined in VA regulations, it would look to the M21-1 for
    interpretive guidance, which stated that "the following locations are considered to be offshore
    waters of the Republic of Vietnam: Da Nang Harbor, Nha Trang Harbor, Qui Nhon Bay Harbor,
    Cam Rahn Bay Harbor, Vung Tau Bay Harbor, and Ganh Rai Bay."18 Moreover, the Board 
    cited 13 Rawle at 1428
    (initial claim for benefits), 1642 (May 2013 VA rating decision), 1380-81 (Notice of
    Disagreement), and 1334 (Aug. 2014 Substantive

    our decision in Gray v. McDonald and stated that, as a result of the Court's decision in that matter,
    VA had updated its policy to treat all bays and harbors in the same way concerning the inland—
    versus—offshore classification and the M21-1 now provided that "all harbors and bays are
    considered offshore, while all rivers and deltas are considered inland."19
    After providing this general explanation, the Board addressed the appellant's claim
    specifically both on a direct and presumptive exposure basis. As to direct exposure, the Board
    discounted the appellant's lay statements finding that he had not demonstrated that he was
    competent to identify herbicides to which he might have been exposed, and the Board provided
    little probative value to the private medical evidence of record. 20 Thus, the Board denied
    entitlement on a direct basis for lack of nexus evidence. The Board made short work of entitlement
    to service connection on a presumptive basis because the M21-1 categorically excluded harbors,
    such as Da Nang, from presumptive exposure to Agent Orange.21 The Board adopted that position
    without discussing why it had decided to follow the M21-1's guidance.22 This appeal followed.
    II. PARTIES' ARGUMENTS
    The appellant argues that his service aboard the U.S.S. Providence supports his claims for
    service connection for diabetes and ischemic heart disease. First, he asserts that he is entitled to
    the presumption of service connection based on herbicide exposure. He argues that the Board erred
    when it, without analyzing the probability of herbicide exposure, found he was excluded from the
    presumption by relying on a an M21-1 provision that service aboard a ship anchored in Da Nang
    Harbor did not constitute inland waterway service. He alleges that the Board essentially rendered
    the same analysis that the Court rejected in Gray, and thus, remand is warranted.
    Further in connection with the presumption, the appellant seeks clarification of the Court's
    decision in Gray to ensure that VA applies the proper standard of review in matters like his. He
    asserts that the Board is required to determine, based on the particular evidence in his case, whether
    it is at least as likely as not that there were levels of herbicides present in Da Nang Harbor 
    sufficient 19 Rawle at 10

    .
    22
    
    Id. 4 to
    justify the herbicide exposure presumption, not whether it is probable that he was exposed to
    herbicides.
    Finally, the appellant claims that, regardless of the presumption, he established the
    likelihood of direct herbicide exposure. He argues that the Board's contrary finding is either clearly
    erroneous or not supported by an adequate statement of reasons or bases.
    The Secretary responds that the Board properly applied VA's policy according to the law
    and this Court's Gray decision. He asserts that the Gray Court focused on the inconsistency of
    deeming certain harbors as "inland waterways" and designating others "offshore waterways,"
    "only finding issue with the inconsistent manner in which it was previously done."23 He also asserts
    that since VA revised its policy, it is no longer inconsistent because it establishes a firm, bright-
    line rule—exclusion of service in all bays and harbors from presumptive herbicide exposure. And
    as to direct exposure, the Secretary argues that the Board's decision was not erroneous and was
    supported by adequate reasons or bases.
    At oral argument, the appellant insisted that remand in light of the Court's decision in Gray
    is warranted for the Board to find independently whether he is entitled to the presumption based
    on the probability of exposure. He explained that VA's guidance set forth in the M21-1 is erroneous
    because geographical line drawing fails to take into account the probability of herbicide exposure.
    In other words, he argues that to determine whether Da Nang Harbor is an inland waterway, the
    Board must assess the evidence based on the probability that a veteran's presence in the harbor
    would likely lead to herbicide exposure, and not simply rely on VA's general conclusion set forth
    in the M21-1.
    Though the Secretary did not argue in his brief that VA's current policy on distinguishing
    between inland and offshore waterways is based on a reasonable interpretation of its own
    regulation—38 C.F.R. § 3.307—and warrants Auer deference, he raised that argument for the first
    time at oral argument.24 He further explained that because the M21-1 contains evidence of this
    interpretation, which he argues was formally set forth in the Federal Circuit's Gray v. Secretary of
    Veterans Affairs decision, the Board's reliance on the M21-1 for guidance was proper.

    III. ANALYSIS
    The appellant bases his argument for service connection on two theories. First, he argues
    that he should be entitled to the presumption that he was exposed to herbicides and, therefore, his
    conditions are service connected. 25 Second, he asserts that even if he is not entitled to the
    presumption of exposure, he has sufficiently established actual exposure to Agent Orange. We
    address each theory below.
    A. Presumptive Service Connection
    Veterans who "served in the Republic of Vietnam" between January 9, 1962, and May 7,
    1975, are presumed to have been exposed to certain herbicides, including Agent Orange.26 And a
    second presumption provides that certain conditions, including type II diabetes and ischemic heart
    disease, are the result of such exposure.27 "Service in the Republic of Vietnam includes service in
    the waters offshore and service in other locations if the conditions of service involved duty or
    visitation in the Republic of Vietnam."28 In Haas v. Peake, the Federal Circuit examined the
    validity of limiting the herbicide presumption to service members who set foot on land in Vietnam
    or who served in the inland waterways of that nation.29 The court concluded that it was reasonable
    for VA to make such distinctions based on the probability of exposure to herbicides.30
    In Gray v. McDonald, this Court considered VA's regulation designating certain
    Vietnamese bays and harbors as "inland waterways" (brown water) or "offshore seas" (blue water)
    in light of Haas.31 The Court explained that VA's definition of "inland waterway" was arbitrary
    and capricious because it designated some harbors and bays as brown water and some as blue
    water without basing the designations on the probability of herbicide exposure, including exposure
    to Agent Orange.32 Therefore, the Court determined that VA's interpretation was not entitled to
    deference and remanded the matter for VA to reevaluate its definition.33

    Less than a year after our decision in Gray, VA modified its policy in the M21-1, adopting
    an interpretation that excluded all Vietnamese bays and harbors from the herbicide presumption.
    VA redefined inland waterways as
    water rivers, streams, and canals, and similar waterways. Because these waterways
    are distinct from ocean waters and related coastal features, service in these
    waterways is service in the [Republic of Vietnam]. VA considers inland waterways
    to end at their mouth or junction to other offshore water features, as described
    below. For rivers and other waterways ending on the coastline, the end of the inland
    waterway will be determined by drawing straight lines across the opening in the
    landmass leading to the open ocean or other offshore feature, such as a bay or inlet.
    For the Mekong and other rivers with prominent deltas, the end of the inland
    waterways will be determined by drawing a line across each opening in the
    landmass leading to the open ocean.34
    Shortly thereafter, Mr. Gray, along with the Blue Water Navy Vietnam Veterans
    Association, directly petitioned the Federal Circuit to invalidate this change to the M21-1. 35
    Ultimately, the Federal Circuit concluded that it lacked jurisdiction to review the M21-1, and
    dismissed the direct regulatory challenge.36 The Federal Circuit concluded it lacked jurisdiction to
    consider the challenge because the Board is not bound by the M21-1. 37 This meant that the
    provision being challenged was not "substantive" under the APA.38
    Putting all this together, we know first that VA is permitted to draw reasonable lines
    demarcating inland versus offshore waterways when considering whether a veteran is entitled to
    the presumption of herbicide exposure.39 Second, when drawing such a line, VA must do so in a
    reasoned, nonarbitrary manner focused on the likelihood of herbicide exposure.40 And finally, the
    Board is not bound by M21-1 provisions.41 With this guidance, the Court will evaluate the Board's
    decision on appeal.

    In the decision on appeal, the Board recounted much of the history we have set forth
    concerning the presumption of herbicide exposure.42 The Board described the holding in Haas,
    this Court's decision in Gray, and the subsequent revision of the M21-1.43 But the Board provided
    nothing more than this historical recitation to support its conclusion that Da Nang Harbor is not
    brown water warranting presumptive herbicide exposure. Instead, the Board tersely stated that the
    "new guidance," referring to its earlier discussion of the M21-1 provision, deems all harbors or
    bays offshore, and all rivers and deltas inland.44 This is error.
    The Federal Circuit made it clear that the Board is not bound by the M21-1.45 This holding
    is meaningful. To support its decision the Board can't simply cite an M21-1 provision without
    further analysis. First, doing so would effectively negate the Federal Circuit's decisions in Gray
    and DAV. Doing so would convert the M21-1 into substantive rules as a practical matter without
    providing a means to challenge such rules under the APA. Second, because the M21-1 is not
    binding on the Board, the Board's citation to a manual provision as the only support for a
    conclusion–here that Da Nang Harbor is blue water–is inconsistent with the Board's
    congressionally mandated obligation to provide an adequate statement of reasons or bases for its
    decisions.46
    There is no question that the M21-1 provision defining "inland" and "offshore" waterways
    is relevant to the issues at hand. Indeed, the Board referred to that provision as VA's "new
    guidance."47 The Board can't ignore such a relevant provision. But it is equally insufficient for the
    Board to simply rely on an M21-1 provision, like the one at issue here, without first independently
    reviewing the matter. The Board is required to provide a reasoned explanation for why it finds the
    M21-1 an accurate guideline for its decision. In other words, the Board is required to discuss any
    relevant provisions contained in the M21-1 as part of its duty to provide adequate reasons or bases,
    but because it is not bound by those provisions, it must make its own determination before it
    chooses to rely on an M21-1 provision as a factor to support its decision. Therefore, the

    concludes that though the Board was correct in acknowledging the relevance of the M21-1
    provision delineating inland and offshore waterways, the Board failed to explain in any way why
    it relied on that position. This failure renders its statement of reasons or bases insufficient for
    judicial review and necessitates remand.48
    Further, the Board appears to suggest that an all-or-nothing rule, stating that all bays and
    harbors are or are not inland waters, automatically alleviates the problem this Court identified in
    Gray.49 This is not correct. The Court in Gray made clear that there must be some rationale for
    deciding what makes a bay or harbor an inland or offshore waterway.50 Because there was no
    rhyme or reason for why VA was designating some waterways but not others as inland waters, the
    designation was inconsistent with the purpose of the regulation establishing the presumption—to
    compensate veterans based on the probability or likelihood of exposure to herbicides.51 This was
    the rationale for the Court's decision in Gray. The Board erred to understand otherwise. The issue
    was not merely a lack of uniformity. Thus, on remand, the Board must explain why its
    determination of entitlement to presumptive service connection is based on likely herbicide
    exposure and achieves the purpose behind the regulation.52
    Before moving on, the Court must address one final matter concerning presumptive
    herbicide exposure. For the first time at oral argument, the Secretary suggested that the Court
    should defer to his interpretation in the M21-1 under Auer v. Robins.53 This argument appears
    nowhere in the Secretary's brief – indeed, Auer is not even cited.54 For three reasons, the Court
    declines to consider deference under Auer.

    The appellant rather confusingly argues that the Board misconstrued the Court's holding in Gray when it
    analyzed the evidence of record based on whether it is probable that he was exposed, rather than rendering a
    determination whether it is "at least as likely as not" that he was exposed to herbicides. See Appellant's Br. at 26-27.
    He seems to argue that Gray adopted an evidentiary standard. It did not. Gray was concerned with whether a regulation
    was lawful. It in no way changed any evidentiary standard or burden of proof.

    First, the Court has made clear that it "generally will not entertain arguments raised by
    counsel at oral argument for the first time."55 Such conduct is not helpful to the Court and is
    fundamentally unfair to opposing counsel. This alone is a reason not to consider the argument.56
    Second, there is nothing special about deference under Auer that suggests that an argument
    concerning that doctrine can't be waived by failing to raise it in the brief. Both this Court and the
    Federal Circuit have specifically found Auer arguments to be subject to waiver.57
    Third, even if the Auer argument had not been waived, it would be misplaced here. We are
    not reviewing the position set forth in the M21-1. After all, the M21-1 provision is not a substantive
    rule of law.58 Rather, we are reviewing the final Board decision on the appellant's claims.59 As we
    explained, the Board's decision is deficient because the Board did not explain why it relied on the
    M21-1 and its conclusions concerning the brown water/blue water distinctions for Vietnamese
    harbors and bays. Thus, we are not called on to express any view about what the M21-1 says, and
    we don't. In essence, there is nothing to defer to here because in terms of the Board's rationale for
    adopting the M21-1's position, the Board's decision is deficient as a matter of law.
    In sum, because the Board did not adequately explain the bases for its decision on
    presumptive herbicide exposure, remand is required.60 We now turn briefly to the other issues this
    appeal raises.

    to Agent Orange does not preclude direct service connection for other conditions based on Agent
    Orange exposure."61 Here, the Board also denied the appellant entitlement to service connection

    for type II diabetes and ischemic heart disease on a direct basis due to herbicide exposure. The
    Board concluded that the weight of the probative evidence of record was against finding that the
    appellant was exposed to herbicides while stationed aboard the U.S.S. Providence when it was in
    Da Nang Harbor.62 The appellant argues that the Board's finding is clearly erroneous,63 or, in the
    alternative, is not supported by an adequate statement of reasons or bases.64
    The Court declines to address the appellant's arguments at this time. As explained above,
    we are remanding this matter as it relates to presumptive service connection so that the Board may
    adequately explain why Da Nang Harbor should or should not be considered brown water for
    purposes of the presumption of herbicide exposure. Consistent with our decision in Gray, that
    assessment must be made based on the likelihood of exposure to herbicides. The analysis (and
    potential development associated with that effort) in which the Board may engage with respect to
    the presumptive exposure question may affect the Board's assessment of direct exposure.
    Given all of this, we are not confident that the direct exposure claim is sufficiently
    independent of the presumptive exposure claim to resolve the matter at this point. For example,
    we don't know how the Board will develop the record to support its conclusion on Da Nang
    Harbor's status concerning presumptive herbicide exposure. That development could easily
    implicate the direct exposure analysis. Thus, and given the potential interconnectedness of these
    matters, we conclude that remand of the direct exposure theory is advisable.65
    C. Other Matters
    The appellant also challenges the Board's determination that VA's duty to assist has been
    satisfied and claims that his due process rights have been violated. Because the Court has
    determined that remand is necessary, it need not consider these arguments.66 In pursuing his case
    on remand, the appellant is free to submit additional evidence and argument, including the specific
