Alameda Gateway (“Gateway”) appeals the district court’s grant of summary judgment in favor of the Army Corps of Engineers (“Corps”) and its denial of Gateway’s cross-motion for summary judgment. The Corps removed portions of Gateway’s piers pursuant to its authority under section 10 of the Rivers and Harbors Appropriation Act of 1899 (“RHA”). See 33 U.S.C. § 403. Gateway’s piers were located in the Oakland Harbor (“Harbor”) and were removed in order to create a turning basin that would improve accessibility for larger vessels and consequently increase the volume of cargo entering Oakland. See Water Resources and Development Act of 1986 § 202, Pub.L. No. 99-662, 100 Stat. 4082, 4092 (“WRDA”).
The Corps sued Gateway in federal district court to recover the costs associated with the removal, claiming that the RHA furnished it with a removal and reimbursement remedy. The district court agreed and granted summary judgment in favor of the Corps. We have jurisdiction under 28 U.S.C. § 1291, and we affirm.
I.
Gateway owns a 29-acre marine industrial site on the Alameda side of the Oakland Harbor. When Gateway acquired the property in 1983, it acquired two piers, an eastern and western pier, each extending approximately 600 feet into the Harbor. The western pier stands on both the submerged parts of Gateway’s property and on submerged land leased to Gateway by the City of Alameda. The eastern pier stands entirely on submerged portions of Gateway’s property and is badly deteriorated.
Most of Gateway’s property that lies within the proposed turning basin was originally conveyed into private ownership by Governor Pablo Vicente de Sola of California, acting under the authority of the Spanish Government in 1820. The property was conveyed to the Peralta family as part of the Rancho San Antonio. The United States agreed to honor private land grants, including the grant made to the Peralta family, in the Treaty of Guadalupe Hidalgo.
The property then changed hands several times until it was purchased by United Engineering Company (“United”) prior to World War II. Between 1941 and 1943, United dredged the property to create a basin. Shortly after the dredging work was completed, United constructed the two piers without a permit. These piers are the subject of this appeal. The United States then took title to the piers and leased them to United.
*1164 In 1970, the United States sold its interest in the property, including the two piers, to Todd Shipyard Corporation (“Todd”). Gateway purchased the property from Todd thirteen years later. Shortly after purchasing the property, Gateway applied to the Corps for a permit to develop a marina. The application was denied because the Corps had already started to make preparations with the Port of Oakland (“Port”) to create the turning basin. Gateway sued the Corps in federal district court to compel the issuance of a development permit, but no decision was ever reached in that case. 1
In 1986, Congress, among other things, authorized the construction of the proposed turning basin by passing the WRDA. See WRDA § 202, Pub.L. No. 99-662, 100 Stat. 4082, 4092. Prior to the project, the Harbor was unable to accommodate larger vessels except during high tide and when the ships were not fully loaded. The purpose of the project, therefore, was to make the Port competitive by deepening and widening the shipping channels in addition to providing a turning basin for larger ships.
The Corps determined that it would need to remove portions of Gateway’s piers in order to create a safe turning basin. As a result, the Corps moved the harbor line shoreward and notified Gateway that the piers were an obstruction to navigation and that Gateway needed to submit a plan to remove the piers at its own cost. See 38 U.S.C. §§ 403, 406. Gateway refused to submit a removal plan, and the Corps decided to remove the piers on its own in order to keep the project on schedule.
The United States initiated this action by filing a motion in federal district court for an injunction preventing Gateway from interfering with the removal of the piers. The district court granted that motion and the pier ends were subsequently removed by the Corps. Following the removal, the Corps filed a motion for summary judgment, arguing that Gateway was responsible for the $1,677,186.08 in demolition and removal costs paid by the Corps. Gateway opposed the motion and filed a cross-motion for summary judgment. The district court granted summary judgment in favor of the United States and awarded removal costs. Gateway’s cross-motion was denied and this appeal followed. 2
II.
Ordinarily, the denial of summary judgment is not a final order and is thus unappealable.
See Abend v. MCA, Inc.,
This Court reviews both a denial and grant of summary judgment de novo.
See DeBoer v. Pennington,
*1165 III.
The power of the United States to regulate navigable waters is grounded in the Commerce Clause of the Constitution.
See
U.S. Const, art. I, § 8, cl. 3;
Boone v. United States,
Pursuant to its regulatory authority over navigable waters, Congress enacted the River and Harbors Appropriation Act of 1899. See 33 U.S.C. § 401 et seq. The first clause of section 10 of the RHA prohibits the creation of any obstructions in navigable waters. See 33 U.S.C. § 403. It states: “The creation of any obstruction not affirmatively authorized by Congress, to the navigable capacity of any of the waters of the United States is prohibited.” Id. As the Corps readily admits, its sole remedy lies in this first clause of section 10. The focus of this appeal, therefore, is the breadth of the remedy provided by section 10.
A.
The first issue is whether Gateway’s piers constituted an “obstruction” under section 10 of. the RHA. In
Sierra Club v. Andrus,
The evidence in the record supports rather than rebuts the presumption that Gateway’s piers were an obstruction to the navigable capacity of the Harbor. The Corps expressly determined that portions of Gateway’s piers prevented the creation of a turning basin that could safely accommodate larger vessels entering the Harbor, providing support for the Corps’ election to remove the piers under section 10. Gateway fails to rebut the presumption or present any evidence to the contrary. The district court, therefore, correctly concluded that the piers constituted an obstruction under section 10 of the RHA. 3
B.
Gateway’s primary argument is that a removal and reimbursement remedy is available to the Corps only when one of three conditions is met: (1) The piers were within the navigational servitude; (2) the piers were built pursuant to a permit issued by the Corps; or (3) Gateway was culpable. We disagree.
The starting point for our analysis is section 12 of the RHA. See 33 U.S.C. § 406. That provision states: “[T]he removal of any structures or parts of structures erected in violation [of section 403] may be enforced by the injunction of any district court exercising jurisdiction in any district in which such structures may exist.” Id. While the statutory text of section 12 allows the Corps to seek an injunction to compel the removal of structures violating section 10, it conspicuously omits any reference to a removal and reimbursement remedy in favor of the United States. Thus, if such a remedy exists, it must be implied.
Supreme Court precedent suggests that the Corps may perform the removal work *1166 itself and then collect the costs of such work from private parties even though the RHA does not expressly authorize such a remedy. The Supreme Court has discussed the applicability of a removal and reimbursement remedy under the RHA, though the remedy has not been applied to a violation of section 10. We do not find that distinction significant, however, because the Supreme Court has repeatedly stated that the statutory remedies in the RHA are not exclusive.
In
United States v. Republic Steel Corp.,
The Supreme Court reinforced its willingness to imply additional remedies into the RHA in
Wyandotte Transportation Co. v. United States,
Wyandotte Transportation Company
is particularly significant because section 15 does not even authorize an injunctive remedy in favor of the United States.
See id.
at 199,
The reasons for implying a self-help remedy for violations of section 10 are even more pronounced. In contrast to section 15, section 12 expressly provides for an injunctive remedy allowing the United States to compel an owner to remove an obstruction. When injunctive relief is already available, the case for implying a self-help remedy is even stronger.
See United States v. Perma Paving Co.,
Although the authority is scant with regard to the availability of a removal and reimbursement remedy, the two cases that have considered the issue have reached the conclusion that such a remedy is available for violations of section 10.
See id.; United States v. Illinois Terminal R.R. Co.,
Furthermore, Gateway’s assertion that the Corps cannot remove a lawfully erected structure is equally unavailing. As the district court pointed out, the RHA allows the United States to remove structures that were once erected lawfully but subsequently found to be obstructions.
See, e.g., Greenleaf-Johnson Lumber Co. v. Garrison,
IV.
Gateway next argues that the Corps failed to follow its own regulations when it removed Gateway’s piers. See United States Army Corps of Engineers, Engineering Regulation 1165-2-131 § 11(d), at 31 (“Engineering Regulation”). Specifically, Gateway points to section 11(d)(6) of the Engineering Regulation which requires that two prerequisites be met prior to the exercise of “federal authorities”: (1) the local sponsor fails to reach an agreement with the owners of the property despite every reasonable effort; and (2) the local sponsor lacks the power to force the owners to give up their property. See id. Gateway alleges that the second condition was not met because the City of Alameda had the power to condemn Gateway’s property and therefore the Corps’ exercise of its RHA authority was premature. We need not reach that issue, however, because the Engineering Regulation is not binding on the Corps.
A.
Although the parties failed to raise the issue in either the briefs or the district court, our case law is clear that “we will not, review allegations of noncompliance with an agency statement that is not binding on the agency.”
Western Radio Servs. Co. v. Espy,
Furthermore, the Supreme Court has recognized that a court of appeals does not abuse its discretion when it raises the validity of a law even when the parties failed to raise the issue in the briefs or before the district court.
See United States Nat’l Bank of Oregon v. Independent Ins. Agents of Am.,
B.
For a regulation to have the force and effect of law, it must: “(1) Prescribe’ substantive , rules-not interpretive rules, general statements of policy or rules of agency organization, procedure or practice-and; (2) conform to certain procedural requirements.”
United States v. Fifty-Three Eclectus Parrots,
For a rule to be labeled as substantive rather than interpretive, “the rule must be legislative in nature, affecting individual rights and obligations.”
James v. United States Parole Comm’n,
Accordingly, Gateway cannot rely on the Engineering Regulation because it was not intended to have the force of law, but was instead a policy statement to guide the practice of district engineers.
See James,
V.
Gateway’s final contention on appeal is that it was denied due process because it was ordered to destroy its own property. Gateway presents this argument in a lone,footnote and fails to cite any authority in support. Indeed, it is difficult to determine the type of due process violation that Gateway is alleging. Accordingly, Gateway has waived this issue on ap

peal.
See Big Bear Lodging Ass’n v. Snow Summit, Inc.,
AFFIRMED.
Notes
. Following the denial of the development permit, Gateway applied for a maintenance permit to work on the badly deteriorated eastern pier. The Corps agreed to grant the permit but only if Gateway consented to removal of the eastern pier once the Corps was prepared to begin the dredging work for the turning basin. Gateway elected not to perform the maintenance work until the dispute with the Corps was resolved.
. Following the removal of the piers, Gateway filed a Fifth Amendment takings claim against the United States in the Court of Federal Claims ("CFC”).
See Alameda Gateway, Ltd. v. United States,
. Gateway concedes that the piers lie within the "navigable capacity of any of the waters of the United States.” 33 U.S.C. § 403. Thus, it is unnecessary for this Court to address that issue.
