OPINION AND ORDER
MARK S. DAVIS, District Judge.
This matter is before the Court on Defendants’ consolidated post-trial motion for judgment of acquittal on Counts 5, 6, 8 and 9. ECF No. 113. The primary focus of Defendants’ motion is the assertion that the above referenced counts are multiplicitous. For the reasons set forth below, Defendants’ motion is DENIED.
I. Factual and Procedural Background
During calendar year 2012, defendant Diana Shipping Services, S.A. (“Diana Shipping”), operated the Motor Vessel Thetis (“M/V Thetis”), a 40,000 gross ton foreign-flagged vessel engaged in international commercial maritime operations. During relevant portions of 2012, defendant Ioannis Prokakis and defendant Antonios Boumpoutelos served, respectively, as the Chief Engineer and the Second Engineer on board the M/V Thetis (the three defendants are collectively referred to herein as “Defendants”). The charges in the superseding indictment stem from Defendants’ alleged involvement in failing to accurately document their overboard discharges of machinery space bilge water from the M/V Thetis. Pursuant to international law, such discharges, which occurred in waters outside the United States, should have been filtered through a pollution control device known as an “Oily Water Separator.” See Benedict S. Gullo, The Illegal Discharge of Oil on the High Seas: The U.S. Coast Guard’s Ongoing Battle Against Vessel Polluters and a New Approach Toward Establishing Environmental Compliance, 209 Mil. L.Rev. 122, 137-42 (2011) (discussing the International Convention for the Prevention of Pollution from Ships (MARPOL) and the implementation of such international agreement in the United States). Defendants’ offenses were reported to the United States Coast [723]*723Guard through a “whistleblower” engine room crewmember that was on board the M/V Thetis in 2012. As a result of such tip, the M/V Thetis was boarded by the United States Coast Guard in Norfolk, Virginia, on September 22, 2012. In the months preceding the September 22 boarding, the M/V Thetis entered the port of Newport News, Virginia, on May 2, 2012, and again on July 8, 2012. However, no Coast Guard boarding or investigation took place during such earlier port calls.
On July 24, 2013, this Court began a two-week criminal bench trial in this matter. At the conclusion of the government’s case, Defendants filed a written Rule 29 motion challenging the government’s evidence with respect to Counts 5, 6, 8 and 9 of the superseding indictment, claiming that such evidence failed to demonstrate that the actus reus and mens rea for the alleged offenses occurred within the jurisdiction of the United States.1 ECF No. 94. Count 5 (May 2, 2012 port call) and Count 6 (July 8, 2012 port call) allege that Defendants “did knowingly conceal, cover up, and falsify and make a false entry in a record and document, that is, a false, fictitious and misleading Oil Record Book for the M/V Thetis,” in violation of 18 U.S.C. § 1519. ECF No. 30, at 15-16. Count 8 (May 2, 2012 port call) and Count 9 (July 8, 2012 port call) allege that Defendants “did knowingly conceal and cover up a tangible object, that is, bypass piping used on the M/V Thetis that was used to discharge ... machinery space bilge water directly into the sea by circumventing required pollution prevention devices,” in violation of 18 U.S.C. § 1519. ECF No. 30, at 17-19. Additionally, at trial, Defendants made an oral Rule 29 motion for judgment of acquittal as to all counts of the superseding indictment based on a general sufficiency of the evidence argument. At the conclusion of the trial, the Court orally denied both Rule 29 motions and found all three Defendants guilty of all charged counts.
Subsequent to trial, Defendants jointly filed the instant Rule 29 motion, again challenging Counts 5, 6, 8 and 9 of the superseding indictment. As discussed below, while the focus of Defendant’s prior Rule 29 motion was jurisdictional, the focus of the instant motion is the assertion that the disputed counts are multiplicitous. Defendants’ joint motion has been fully briefed and is now ripe for review.
II. Standard of Review and Jurisdictional Note
Federal Rule of Criminal Procedure 29 allows a district court to enter a judgment of acquittal for “any offense on which the evidence is insufficient to sustain a conviction.” Fed.R.Crim.P. 29(a). The court must deny such a motion and sustain a guilty verdict in a criminal case tried by a jury “ ‘if there is substantial evidence, taking the view most favorable to the Government, to support it.’ ” United States v. Cameron, 573 F.3d 179, 183 (4th Cir.2009) (quoting United States v. Burgos, 94 F.3d 849, 862 (4th Cir.1996) (en banc)). “ ‘[Substantial evidence is evidence that a reasonable finder of fact could accept as adequate and sufficient to support a conclusion of a defendant’s guilt beyond a reasonable doubt.’ ” Id. (quoting Burgos, 94 F.3d at 862).
[724]*724Although it is undisputed that this Court lacks jurisdiction over improper discharges of oil made by a foreign flagged vessel in international waters, it is likewise undisputed that the Court has jurisdiction over associated record keeping violations that occur within U.S. waters. Pursuant to the international MARPOL treaty of which the United States is a signatory, Congress enacted the Act to Prevent Pollution from Ships (“APPS”). See Angelex Ltd. v. United States, 723 F.3d 500, 502 (4th Cir.2013) (citing 33 U.S.C. §§ 1901-15). Pursuant to APPS, while in U.S. territorial waters, a vessel must “maintain” an Oil Record Book (“ORB”). Id. (citing 33 C.F.R. § 151.25). The regulatory requirement that an ORB be “maintained” has been interpreted to require that a ship entering U.S. waters possess and “maintain” an accurate ORB. See id. (“ ‘[W]e read the requirement that an oil record book be “maintained” as imposing a duty upon a foreign-flagged vessel to ensure that its oil record book is accurate (or at least not knowingly inaccurate) upon entering the ports [or] navigable waters of the United States.’ ” (quoting United States v. Jho, 534 F.3d 398, 403 (5th Cir.2008))).
Here, Defendants were charged with a § 1908 APPS violation for each 2012 port call in this jurisdiction during which they failed to maintain an accurate ORB. Additionally, for each such port call, Defendants were charged with one § 1519 violation for having falsified/covered up the ORB and a second § 1519 violation for having concealed the physical bypass pipe that was used to bypass the onboard pollution control equipment and discharge overboard the M/V Thetis’ machinery space bilge water.
III. Discussion
A. Renewed Argument
Defendants’ written Rule 29 motion that was submitted during trial argued that the government’s evidence with respect to Counts 5, 6, 8 and 9, was insufficient to demonstrate that the actus reus and mens rea for the alleged offenses occurred within the jurisdiction of the United States.2 Defendants also made an oral motion generally challenging the sufficiency of the evidence as to all counts. To the extent that Defendants’ instant motion again raises a jurisdictional challenge, or again challenges generally the sufficiency of the evidence, such motion is denied for the same reasons the Court stated on the record on August 8, 2013. See United States v. Taohim, 529 Fed.Appx. 969, 974 (11th Cir.2013) (rejecting the defendant’s argument that he “could not have intended to impede, obstruct, or influence the Coast Guard’s investigation [in violation of § 1519] when he allegedly ordered the omission ... from the garbage record book because at that time, the vessel was outside the territory of the United States and no investigation was pending,” because the jury rationally could have concluded that the defendant “anticipated that the garbage record book would be reviewed in a future [Coast Guard] proceeding and that he ordered it falsified for that reason”); see also United States v. Royal Caribbean Cruises, Ltd., 11 F.Supp.2d 1358, 1364 (S.D.Fla.1998) (noting that the “extraterritoriality doctrine” provides an alternative basis for jurisdiction over false statements made in international waters if the defendant intends the extraterritorial acts to have an effect within the United States (citing United States v. Padilla-[725]*725Martinez, 762 F.2d 942, 950 (11th Cir.1985), United States v. Stuart-Caballero, 686 F.2d 890, 891 (11th Cir.1982), and United States v. Williams, 617 F.2d 1068, 1076 (5th Cir.1980) (en banc))); Güilo, supra, at 144-45 (noting that the False Statements Act and other general criminal laws, to include § 1519, “allow for enforcement of environmental laws beyond the [territorial seas] jurisdictional limitation contained in the APPS”).3
[726]*726B. Newly Asserted Multiplicity Argument
To the extent that Defendants advance a new post-trial “multiplicity” theory seeking dismissal of Counts 5, 6, 8 and 9, such newly advanced theory is denied as untimely because challenges to an indictment are deemed waived if not advanced prior to trial. Alternatively, even if this Court reached the merits of Defendants’ waived claim, such claim would be denied.
1. Multiplicity Must be Raised Pre-trial
Rule 12(b)(3) of the Federal Rules of Criminal Procedure states that a motion “alleging a defect in the indictment” must be filed prior to the commencement of trial. Fed.R.Crim.P. 12(b)(3)(B). Such pre-trial filing requirement applies to the assertion that an indictment is multiplicitous. See United States v. Lawing, 703 F.3d 229, 236 n. 7 (4th Cir.2012) (“[A] defendant must raise a challenge to a defect in the indictment, ie., multiplicity, before trial.” (citing Fed. R.Crim.P. 12(b)(3)(B))) (emphasis added). “[P]ursuant to Rule 12(e), a party that fails to lodge such an objection prior to trial waives his multiplicity defense.” Id. Once waiver has occurred, relief from such waiver “is appropriate only if the moving party demonstrates cause for the failure to [timely] object and actual prejudice resulting from the defect.” United States v. Colton, 231 F.3d 890, 909 (4th Cir.2000).
Here, Defendants failed to raise their multiplicity defense prior to trial, or even during trial, and have not demonstrated good cause why such failure should not constitute a waiver. See United States v. Cabrera-Beltran, 660 F.3d 742, 753 (4th Cir.2011) (“Because the defendant fails to provide a showing of good cause, his [post-trial] claim that the indictment [suffered from multiplicity or duplicity] is waived.”).4 Accordingly, Defendants’ untimely post-trial multiplicity claim is DENIED as waived.
2. Multiplicity Claim Fails on the Merits
Alternatively, even if Defendants had not waived their multiplicity argument, the [727]*727Court would deny the pending motion on the merits. Defendants’ multiplicity argument, distilled to its essence, contends that the proper “unit of prosecution” under § 1519 would permit only one charge per falsified document and/or one charge per actual government investigation. Under such theory, Defendants contend that their conduct can only support a single § 1519 conviction associated with the ORB because their conduct only involved falsification of a single document,5 and there was only a single government investigation— the Port State Control inspection on September 22, 2012. As discussed below, such theory fails on the merits,
a. Unit of Prosecution Established by Statutory Language
The unit of prosecution for a criminal offense determines what separates a single violation of the statute from multiple violations. United States v. Shrader, 675 F.3d 300, 313 (4th Cir.2012). As explained by the United States Supreme Court, “[i]t is Congress, and not the prosecution, which establishes and defines offenses,” and Congressional authority includes the right to define “a statutory offense by its prescription of the allowable unit of prosecution.” Sanabria v. United States, 437 U.S. 54, 69-70, 98 S.Ct. 2170, 57 L.Ed.2d 43 (1978) (internal quotation marks and citations omitted). “Whether a particular course of conduct involves one or more distinct ‘offenses’ under the statute depends on this congressional choice,” and “[f]ew, if any, limitations are imposed by the Double Jeopardy Clause on the legislative power to define offenses.” Id. In order to determine the proper unit of prosecution for a disputed statute, a district court is required to begin with the statutory text. United States v. Elliott, 849 F.2d 886, 889 (4th Cir.1988); see Shrader, 675 F.3d at 313 (noting that, in Shrader, the Fourth Circuit needed to “look no further than the plain words of the statute to reach th[e] conclusion” that the statute at issue makes “the victim, rather than the course of conduct” the proper unit of prosecution). If the text alone is insufficient, a district court must consider the legislative history and “the overall statutory scheme.” Elliott, 849 F.2d at 889. “If, after such examination, the court determines that the statute is ambiguous, it must ‘resolve doubts in favor of lenity for the accused.’ ” United States v. Salad, 908 F.Supp.2d 728, 729 (E.D.Va.2012) (quoting Elliott, 849 F.2d at 889).
Beginning with the plain language of the statute, § 1519 provides:
Whoever knowingly alters, destroys, mutilates, conceals, covers up, falsifies, or makes a false entry in any record, document, or tangible object with the intent to impede, obstruct, or influence the investigation or proper administration of any matter within the jurisdiction of any department or agency of the United States or any case filed under title 11, or in relation to or contemplation of any such matter or case, shall be fined under this title, imprisoned not more than 20 years, or both.
18 U.S.C. § 1519. Such broad statutory language sets forth numerous clauses criminalizing various conduct, including altering, concealing, covering up, falsifying, or making a false entry in, a record, document or tangible object. Regardless of the specific clause invoked, the statute requires that the conduct occur “with the intent to impede, obstruct, or influence” an investigation of, a contemplated investigation of, or the proper administration of, a [728]*728matter within the jurisdiction of a United States department or agency. Id.
Because § 1519 includes numerous clauses setting forth various ways in which such criminal statute can be violated, in order to determine the applicable unit of prosecution, the threshold step is to determine which clause is at issue. Most relevant to Defendants’ argument in this case, the statute includes a clause criminalizing falsifying a document (“falsifies” clause), as well as a clause criminalizing making a false entry in a document or record (“false entry” clause). Additionally, the statute contains a clause criminalizing the concealment of a record, document, or tangible object (“conceals” clause) and a clause criminalizing the covering up of a record, document, or tangible object (“covers up” clause). Defendants’ motion contends that § 1519 can only be enforced once per falsified document and once per concealed object. However, as discussed below, the Court finds that the proper unit of prosecution under the false entry clause of the statute is that each separate and distinct false entry, as contrasted with each physically separate document, is the proper unit of prosecution. Similarly, the Court concludes that temporally separate and distinct acts of “concealment” or “covering up” are sufficient to warrant separate § 1519 charges under such clauses.
In United States v. Schmeltz, 667 F.3d 685 (6th Cir.2011), the United States Court of Appeals for the Sixth Circuit addressed a duplicity challenge to a § 1519 charge, and in so doing, expressly distinguished between the different clauses of § 1519.6 The Schmeltz opinion squarely addressed “whether § 1519 criminalizes the creation of a false document ... or individual false statements” within a doeument. Id. at 688. In resolving the issue, the Sixth Circuit carefully examined the various clauses of § 1519, and squarely addressed the differences in statutory language between the “falsifies” clause and the “false entry” clause. Id. As to the “falsifies” clause, which was the clause at issue in Schmeltz, the court concluded that it was “intended to punish the falsification of a document, rather than specific statements or omissions within a document.” Id. Accordingly, multiple false statements (or omissions) within the same narrative report that documents the events of a single day support a single § 1519 charge. Id. Notably, the defendant in Schmeltz “was not charged with making ‘a false entry,’ but rather the indictment alleged he ‘falsified a document.’ ” Id. The government was therefore not required to include in the indictment a separate count for each individual allegedly false statement (or omission) in the same report. Id. Although the Sixth Circuit was not called upon to expressly define the unit of prosecution for the statute’s “false entry” clause, the court agreed with the government that “the ‘false entry’ charge is usually reserved for entries made on preexisting forms rather than narrative reports.” Id.
Here, if Defendants’ multiplicity claim had not been waived and this Court was called upon to determine the unit of prosecution for the false entry clause of § 1519, the Court would find that the language of the statute itself is sufficient to determine the unit of prosecution. The “false entry” clause, at a minimum, criminalizes each separate knowingly false entry made in a record on a separate and distinct occasion, regardless of whether [729]*729each entry was made in the same historical record book or in a separate single-page document.7 See United States v. Jameson, 972 F.2d 343, 1992 WL 180146, at *9-10 (4th Cir.1992) (unpublished table opinion) (rejecting a multiplicity challenge to an indictment and holding that two slightly different false statements made within the same document supported two separate counts of making a false statement in violation of 18 U.S.C. § 1001); see also Colton, 231 F.3d at 908-09 (indicating that even when the unit of prosecution is the “execution of a scheme to defraud a financial institution, [and] not each act in furtherance of such scheme,” acts that are “chronologically and substantively independent from the other acts charged as the scheme” constitute separate executions, and thus, “courts have found each in a series of separate diversions of funds, separate loans, and separate extensions of a loan agreement, to be a separate execution of a bank fraud scheme properly chargeable in a separate count of the indictment”) (final emphasis added) (internal quotation marks and citations omitted); United States v. Marquardt, 786 F.2d 771, 774 n. 2, 779 (7th Cir.1986) (rejecting a multiplicity challenge in a case involving separate false entries in bank records, made on separate days, in violation of a statute criminalizing “ ‘mak[ing] any false entry in any book, report or statement of or to any such institution’ ” (quoting 18 U.S.C. § 1006)). Additionally, the statute’s plain language unambiguously criminalizes acts performed “in relation to or contemplation of’ a government investigation, and thus, there is no statutory support for Defendants’ contention that § 1519 can be violated only once per actual investigation.
b. Legislative History and Scheme
Furthermore, even if the Court found that the language of the statute itself was unclear, and the Court shifted its focus to the legislative history and overall statutory scheme, Salad, 908 F.Supp.2d at 729, the Court would reach the same conclusion. Notably, the intentionally broad reach of § 1519, which is part of the Sarbanes-Oxley Act of 2002, has been well-documented since its passage.8 Such leg[730]*730islative history and statutory scheme, therefore, at a minimum support the interpretation that the false entry clause separately criminalizes discrete written false entries, made days, weeks, or months apart, in a historical record book used to document activities over the course of several months. Cf. United States v. Sanford, Ltd., 859 F.Supp.2d 102, 123 (D.D.C.2012) (noting that one of the defendants “may be correct that the ORB is bound together in one book, but the precise physical compilation of the documents is immaterial” as the defendants separately, and falsely, documented conduct occurring on separate voyages occurring one year apart). Pursuant to Defendants’ proposed “one document” theory, whether one or more instances of criminal obstructive conduct occurred would be based on whether or not a staple connected multiple sheets of paper, because while separately maintained falsified documents would each support a separate count of conviction, a multi-page document/book that was bound together could only support a single count of conviction. Such a result would ignore the most natural reading of the statute and strain credulity because the number of permissible criminal counts could turn entirely on a business practice regarding the manner in which records are maintained. See United States v. Mason, 611 F.2d 49, 52-53 (4th Cir.1979) (finding that the statute criminalizing making any false statement in conjunction with the acquisition of a firearm creates a transactional unit of prosecution regardless of how many firearms are purchased at the same time; the Fourth Circuit explicitly rejected a statutory interpretation that would support a single count if the seller allowed a buyer to fill out a single ATF form to purchase multiple guns, but would support multiple counts if the seller required a buyer to contemporaneously fill out a separate ATF form for each gun).9 Furthermore, the legislative history of § 1519 and the consideration of the statutory scheme as a whole both indicate that a violation of the statute is in no way tied to an actual government investigation, undercutting Defendants’ contention that a § 1519 violation can only occur once per actual investigation. See S.Rep. No. 107-146 (2002), 2002 WL 863249, at *14-15 (“This statute is specifically meant not to include any technical requirement, which some courts have read into other obstruction of justice statutes, to tie the obstructive conduct to a pend[731]*731ing or imminent proceeding or matter. It is also sufficient that the act is done ‘in contemplation’ of or in relation to a matter or investigation.”) (emphasis added). Defendants’ arguments are therefore rejected after considering the legislative history and statutory scheme.10
c. Alternative Rule of Lenity Analysis
Finally, even if the Court determined that the unit of prosecution for the “false entry” clause was ambiguous after considering the statute itself, the legislative history, and the statutory scheme, application of the rule of lenity could at best support the interpretation that § 1519 separately criminalizes each factually distinct series of false entries or each factually distinct contemplated investigation. Putting such hypothetically narrower readings of the statute into context in this case, one could conceivably argue that there are three more “lenient” interpretations of the statute, but each would still lead to the denial of Defendants’ motion:
(1)a series of false entries in the ORB made over the course of multiple days that were associated with a single improper discharge of machinery space bilge water would constitute a single § 1519 violation because although there were multiple false entries, each was made relatively close in time to conceal a single use of a bypass pipe to improperly discharge bilge water into the ocean (a per discharge transactional approach );11
(2) a series of false entries in the ORB designed to cover up a series of improper discharges of machinery space bilge water made during the same multi-day, or multi-week, sea voyage would constitute a single § 1519 violation because such related entries, all made close in time, were collectively designed to reflect proper handling and disposal of oil products over the course of a single continuous sea voyage (a per voyage continuing conduct approach); or
(3) a series of false entries in the ORB designed to cover up a series of improper discharges of machinery space bilge water made during a series of consecutive multi-day, or multi-week, sea voyages that ultimately terminate in a United States port would support a single § 1519 violation tied to the defendants’ contemplation of a single (potential) Coast Guard boarding and investigation [732]*732when the vessel came into the United States port (a per contemplated federal investigation approach).
Regardless of which hypothetical lenient interpretation was adopted, the disputed counts in the instant indictment would not be multiplicitous because the trial evidence demonstrated that: (1) the improper discharges of machinery space bilge water were made on multiple separate and distinct sea voyages; (2) the ORB was newly falsified to conceal such temporally discrete discharges each time the M/V Thetis entered the ports of Newport News, Virginia, or Norfolk, Virginia; and (3) Defendants contemplated a separate potential Coast Guard boarding/investigation in May of 2012, July of 2012, and September of 2012. See Sanford, 859 F.Supp.2d at 123 (agreeing with the government that “all counts of the Superseding Indictment are proper, and not multiplicitous” because the indictment charged one group of violations for a voyage ending in 2010, and another group of violations for a voyage ending in 2011, and, among other things, such counts thus charge “separate instances of falsification of the ORB” which was “not exactly the same book for each port call-in between the two there were additional false entries and omissions”). Accordingly, even if the Court assumed, arguendo, that the statute was ambiguous, Defendants’ motion would be denied.
d. Bypass Pipe Indictment Counts
Similar to the above analysis, if this Court reached the merits of Defendants’ “unit of prosecution” argument as to the counts of the superseding indictment charging concealment of the physical bilge bypass pipe, the Court would deny such motion on the merits.12 As the trial testimony demonstrated, the bilge bypass pipe was used on multiple discrete voyages to improperly discharge machinery space bilge water directly into the sea. This included the voyages preceding the May 2, 2012 port call, the July 8, 2012 port call, and the September 22, 2012 port call. Each of the three times the M/V Thetis came into the ports of Newport News, Virginia, or Norfolk, Virginia, the bypass pipe was freshly hidden on the roof of the engine control room of the M/V Thetis where it would not likely have been found if the Coast Guard had boarded the vessel. Accordingly, the trial evidence supported three separate charges for concealment because there were, at a minimum, three distinct “concealments” with the intent to obstruct a potential investigation by the Coast Guard.
The broad language of the statute, the legislative history, and the statutory scheme as a whole, all indicate that three factually and temporally distinct concealments, each occurring two months apart, and each involving the physical concealment of a physical object with the intent to thwart a different potential Coast Guard investigation, support three distinct counts for violating the statute. See Jameson, 972 F.2d 343, 1992 WL 180146, at *9-10 (indicating that because the false statements at issue related to the defendant’s assets and liabilities as of the date the statements were made, counts charging the defendant with making false statements in 1987, and separate counts charging the defendant with again making the same false statements in 1988, were not multiplicitous because the government could not obtain a conviction on the latter counts without proving “the additional fact [733]*733that these debts were still owed and property was [still] owned” in 1988). Such conclusion holds even if the Court assumes ambiguity and applies the rule of lenity because the charged concealments were factually distinct, having occurred months apart and involving both separate acts and separate intent to impede separate potential investigations.13 For all of the above reasons, Defendants’ motion is alternatively denied on the merits.
IV. Conclusion
For the reasons set forth above, Defendants’ post-trial motion for judgment of acquittal on Counts 5, 6, 8 and 9 (ECF No. 113) is DENIED. To the extent such motion renews prior Rule 29 arguments made at trial, it is DENIED for the same reasons explained on the record on August 8, 2013. To the extent such motion advances the newly asserted claim that the superseding indictment is multiplicitous, such claim is DENIED as untimely as the Federal Rules of Criminal Procedure deem such claim to be waived if not raised prior to trial. Furthermore, Defendants’ multiplicity argument is ALTERNATIVELY DENIED to the extent that it is proper for this Court to reach its merits.
