¶ 1. The siting of landfills is,

understandably, often fraught with controversy. In response, the State of Wisconsin has seen fit to preempt local neighborly battles for the common good by establishing a statewide landfill regulatory scheme. This case concerns the scope of that statewide scheme for solid waste facilities exempt from regulation under Wis. Stat. § 289.43(8) (2015-16)1—clean fill facilities— vis-á-vis a municipality's zoning powers and certain other local construction permitting requirements.

*283¶ 2. Scenic Pit LLC sought to open a clean fill facility in the Village of Richfield. The Village maintains that a clean fill facility may not be opened and operated at the site Scenic wishes to use because it is not zoned for such activities, and because Scenic must, as a prerequisite, comply with local construction storm water and erosion permitting requirements as well. Scenic, relying on DeRosso Landfill Co. v. City of Oak Creek, 200 Wis. 2d 642, 547 N.W.2d 770 (1996), maintains that the Wisconsin Department of Natural Resources (DNR) has—pursuant to state statute and the administrative rules promulgated thereunder—exempted clean fill facilities from the local approvals identified by the Village, namely, zoning and certain construction storm water and erosion permitting requirements. We agree with Scenic and reverse the circuit court's order granting summary judgment to the Village.

BACKGROUND

¶ 3. Thomas and Danah Zoulek founded Scenic Pit LLC for the purpose of operating a solid waste facility. In October 2014, the Zouleks (through a separate LLC) accepted an offer contingent on financing to purchase an abandoned gravel pit in the Village of Richfield. In the days following, Thomas Zoulek contacted the Village and expressed his desire to use the gravel pit for a "clean fill" facility—a landfill that accepts only certain kinds of low hazard waste under Wis. Stat. § 289.43(8). The Village told Zoulek that current zoning prevented the property from being so used.2 Scenic disagreed and argued that current zoning allowed quarry restoration, which included using *284the property for clean fill. That dispute became moot, however, when the Village passed an ordinance rezoning the property to Rs-1—a designation the parties agree conclusively prohibits use as a landfill, clean or otherwise.

¶ 4. Scenic sought to move forward with the project anyway. It sent a letter to the Village on March 3, 2015 requesting specification of any local approvals it needed to operate the property as a landfill. The Village responded with a list of requirements—among them, amending the Village's comprehensive plan, rezoning the property, applying for a conditional use permit, and obtaining construction storm water and erosion permits along with approval from the Village engineer for "an erosion and sediment control plan." Undeterred, the Zouleks purchased the site of their proposed landfill on May 21, 2015. That same day, the Village board met and passed a resolution "directing the Village Attorney to take any and all measures" to ensure that Scenic complied with zoning and other local approvals. Scenic subsequently sought construction permits from the Village to begin the landfill project, but it did not attempt to acquire the storm water and erosion permits or a change in zoning. The Village denied the construction permits. In order to comply with Wis. Stat. ch. 283 and Wis. Admin. Code ch. NR 216 (Jan. 2017),3 Scenic did apply for and obtain a Wisconsin Pollution Discharge Elimination System *285(WPDES) general permit from DNR for "Construction Site Storm Water Runoff' and erosion control.4

¶ 5. In light of the opposition, Scenic filed this action seeking a declaratory judgment that it need not comply with any local approvals—specifically, the Village's zoning and construction storm water and erosion control ordinances—and a permanent injunction "restraining the Village from interfering with plaintiffs proposed plan."5 Scenic moved for partial summary judgment on whether it was "required to obtain any local approvals, as defined in [Wis. Stat.] § 289.33(3)(d)." The Village also moved for summary judgment and sought dismissal of the complaint. The circuit court denied Scenic's motion and ordered summary judgment be granted in favor of the Village. The court reasoned that per Willow Creek,6 discussed later in this opinion, Scenic must comply with all local ordinances unless "state and local interests are diametrically opposed." Because the Village's zoning and storm water and erosion ordinances were not diametrically opposed to the state interests, the court concluded that Scenic remained subject to these requirements. Scenic appeals from this order.

*286DISCUSSION

¶ 6. We review the circuit court's grant or denial of summary judgment de novo. Romero v. West Bend Mut. Ins. Co., 2016 WI App 59, ¶ 17, 371 Wis. 2d 478, 885 N.W.2d 591. Summary judgment is appropriate when there are no disputed material facts and the moving party is entitled to judgment as a matter of law. Id.

¶ 7. The issue before us is whether Scenic is exempt from compliance with "local approvals" as defined in Wis. Stat. § 289.33(3)(d), and whether the Village's zoning and construction storm water and erosion ordinances are such local approvals. Whether the court properly denied Scenic's motion for summary judgment depends on construing various statutes and regulations to determine whether they preempt the Village's zoning ordinance and storm water and erosion regulations. These are questions of law we review de novo. DeRosso, 200 Wis. 2d at 652. We hold, consistent with DeRosso, that Scenic need not comply with the Village's zoning and construction storm water and erosion requirements because the legislature has expressly withdrawn the Village's power to act.

¶ 8. The legislature has designated the regulation of solid waste facilities like the one proposed by Scenic a matter of statewide concern, and therefore appropriate for a statewide regulatory scheme.7 Wis. *287Stat. § 289.33(3)(c), (5)(a); DeRosso, 200 Wis. 2d at 650. However, this designation does not necessarily foreclose local action. A municipality may regulate matters of statewide concern so long as "such ordinances do not conflict with. . . the state legislation." DeRosso, 200 Wis. 2d at 651. Ordinances that conflict are preempted by state law. Id. An ordinance is preempted when any of the following four tests are satisfied: (1) the legislature has expressly withdrawn the power of the municipality to act, (2) the ordinance logically conflicts with state legislation, (3) the ordinance defeats the purpose of state legislation, or (4) the ordinance violates the spirit of state legislation. Anchor Sav. & Loan Ass’n v. Equal Opportunities Comm'n, 120 Wis. 2d 391, 397, 355 N.W.2d 234 (1984); see also DeRosso, 200 Wis. 2d at 651-52. Thus, the preemption question is generally one that must be answered with regard to the unique statutory scheme at issue.

¶ 9. The solid waste regulatory scheme prescribes a robust and comprehensive process involving state and local authorities for the siting and construction of solid waste facilities. Before establishing a solid waste facility, an applicant must file an initial site *288report with DNR and request an itemized list of local approvals from the affected municipality. See Wis. Stat. §§ 289.21 & 289.22(1m). After the request for local approvals, the affected municipalities may—by adopting a siting resolution—choose to participate in a process of negotiation and arbitration overseen by the waste facility siting board. See Wis. Stat. § 289.33(6). If a siting resolution is passed, then negotiation begins between the applicant and a "local committee" made up of various affected municipalities. Sec. 289.33(7), (9). If this process fails to yield an agreement, then the parties may arbitrate the matter before the waste facility siting board. Sec. 289.33(10). In addition to the above procedure, the applicant must file a feasibility report and a plan of operation with DNR. Wis. Stat. §§ 289.23 & 289.30. After an applicant jumps through all of the preceding hoops, DNR then issues an operating license. Wis. Stat. § 289.31(1), (3).8 Our supreme court observed that this may be an expensive process that can take years. See DeRosso, 200 Wis. 2d at 659 n.14.

¶ 10. However, the legislature has given DNR discretion to exempt certain low-hazard waste facilities—i.e., clean fill facilities like the one proposed by Scenic—from this more exacting regulation. See Wis. Stat. § 289.43(8); see also DeRosso, 200 Wis. 2d at 653 (explaining that the predecessor statute to § 289.43 "authorizes the DNR to exempt low-hazard waste facilities" from certain statutory and regulatory *289requirements).9 Pursuant to this statutory authority, DNR promulgated Wis. Admin. Code § NR 500.08 exempting operators of clean fill facilities from compliance with "the requirements of [Wis. Admin. Code] chs. NR 500 to 538." Among the exempted provisions is the requirement in Wis. Admin. Code § NR 512.06(1) to "apply for all applicable local approvals specified by a municipality." See DeRosso, 200 Wis. 2d at 653 & n.10. The scope of "local approval" as defined in Wis. Stat. § 289.33(3)(d) is addressed below.

¶ 11. Whether Wis. Stat. § 289.43(8) coupled with DNR regulations expressly withdraws the power of municipalities to require compliance with "local approvals" (as defined) for clean fill facilities was squarely addressed by the supreme court in DeRosso. The answer is yes.

¶ 12. In DeRosso, the plaintiffs sought to open a clean fill facility in the City of Oak Creek. DeRosso, 200 Wis. 2d at 647-48. DNR approved the plaintiffs' proposal. Id. However, citing environmental concerns, Oak Creek passed a resolution forbidding the operation of a clean fill facility. Id. As here, the plaintiffs sought a declaratory judgment and an injunction "restraining the City from interfering with the proposed plan." Id. at 649.

*290¶ 13. Applying the Anchor tests, the Wisconsin Supreme Court held that Wis. Stat. § 289.43 preempted municipal authority to enforce "local approval" requirements for clean fill facilities. DeRosso, 200 Wis. 2d at 662. The court noted that this was an exempt clean fill facility under § 289.43(8). DeRosso, 200 Wis. 2d at 657. Its statutory analysis was as follows:

With limited exceptions which are not applicable here, Wis. Admin. Code § NR 500.08 exempts clean fill facilities from compliance with Wis. Admin. Code §§ NR 500 to [538]. Consequently, an applicant seeking DNR approval for a clean fill facility is exempt from Wis. Admin. Code § NR 512.06(1), which states that "[a]n applicant subject to [Wis. Stat. § 289.33] shall apply for all applicable local approvals specified by a municipality under [Wis. Stat. § 289.22(lm)]."

Wisconsin Stat. § [289.22(lm)] requires, in pertinent part, that "[p]rior to constructing a solid waste disposal facility or a hazardous waste facility, the applicant shall apply for each local approval required to construct the waste handling portion of the facility."

DeRosso, 200 Wis. 2d at 653 n.10.10 The exemption in § NR 500.08 did not, the court explained, simply restore the City's preexisting authority "to regulate within the same sphere." Id. at 658.

By providing that certain facilities may be exempted from local approval, the legislature has clearly and *291expressly withdrawn municipal power to act as to exempt facilities such as the plaintiffs' site ....

The regulations, enacted pursuant to an express legislative grant of authority in Wis. Stat. § [289.43(8)], exempt clean fill facility operators from the requirement that they apply for local approvals. If such operators need not even apply for local approvals, we fail to see how, as the City suggests, they could nevertheless be subject to them ....

[[Image here]]

In making the determination that clean fill facilities do not pose significant hazards to health and are therefore entitled to an exemption under Wis. Stat. § [289.43(8)], the DNR has not ceded jurisdiction or authority but has proactively exercised its authority to promulgate rules and regulations rendering that exemption effective.

DeRosso, 200 Wis. 2d at 657-59. Thus, the court concluded that § 289.43(8) and § NR 500.08 preempted the City's ordinance under the first Anchor test by expressly withdrawing municipal power to require compliance with local approvals required to construct the clean fill facility.11 DeRosso, 200 Wis. 2d at 657-69.

¶ 14. At oral argument, the Village more or less conceded (as it must) that if DeRosso remains good law, its argument is left with the hair-thin lifeline that zoning is not a local approval under the statute. Hence, the Village directs us to Willow Creek Ranch, LLC v. Town of Shelby, 2000 WI 56, 235 Wis. 2d 409, 611 N.W.2d 693, which the Village contends, "walked back the language in DeRosso by limiting the scope of 'local *292approvals' that are automatically preempted" to only local approvals relating to the operation, not location, of clean fill sites.

¶ 15. In Willow Creek, the plaintiffs sought to open a game bird farm where local zoning prohibited it. Willow Creek, 235 Wis. 2d 409, ¶¶ 4, 6. The plaintiffs maintained that DNR licensing scheme for such farms preempted the local zoning ordinance. Id., ¶ 16. The supreme court disagreed and held that the local zoning ordinance did not conflict with the state regulations. Id., ¶¶ 22-23. The court noted DeRosso and other cases but distinguished them because they "involve local ordinances that attempt to regulate the identical activity as the state and that are 'diametrically opposed' to the state's policy." Willow Creek, 235 Wis. 2d 409, ¶ 22 (quoting Wisconsin's Envtl. Decade, Inc. v. DNR, 85 Wis. 2d 518, 535, 271 N.W.2d 69 (1978)).12

¶ 16. The Village apparently reads this decision as functionally modifying Anchor and establishing a new test in its place to the effect that local regulation is allowed unless it is "diametrically opposed" to state policy.13 See Willow Creek, 235 Wis. 2d 409, ¶ 22. Thus, the Village maintains that its zoning ordinance is not "diametrically opposed" to DNR's licensing scheme and not preempted.

*293f 17. The Village misreads Willow Creek, which rests on analysis of an entirely separate statutory scheme. The court's "diametrically opposed" language —only cited once—reflected the court's conclusion that these prior cases, including DeRosso, involved a direct conflict that did not exist in that case, nothing more. The Willow Creek court did not expressly or impliedly overrule the Anchor preemption tests. Nor did it explicitly address the first Anchor test we rely upon here. It did not expressly or impliedly withdraw any language from DeRosso. It did not address Wis. Stat. § 289.43(8) or Wis. Admin. Code § NR 500.08 or otherwise alter the statutory analysis conducted in DeRosso. See Willow Creek, 235 Wis. 2d 409, ¶¶ 15-23. In short, Willow Creek is entirely consistent with DeRosso; it did not alter its analysis in any way.14

f 18. Furthermore, the Village's cabined reading of DeRosso is not reasonable or consistent with the statute. If the Village is right, and clean fill facilities must comply with local zoning, then a municipality could permanently block the construction of a clean fill facility by rezoning to prohibit landfills, or by having no areas zoned for clean fill, or by providing only one or two limited or impractical locations for such facilities. This would be directly contrary to the purpose of Wis. Stat. § 289.43 as interpreted by DeRosso, 200 Wis. 2d at 663 (explaining that by enacting § 289.43(8), the legislature has provided "that so long as the DNR *294determines that certain low-hazard waste facilities do not significantly jeopardize the environment or public health, their establishment should not be impeded by local rule or ordinance").

¶ 19. In sum, Willow Creek is inapposite. This case is not about local zoning versus statewide licensing authority. Rather, the question here is whether this particular statutory scheme preempts local approvals required to construct a clean fill facility by expressly withdrawing the municipalities' power to act. This statutory interpretation question has been settled by DeRosso, which remains authoritative and unmodified. Local approvals required to construct such a facility, as defined by Wis. Stat. § 289.33(3)(d), are preempted and no longer required for exempt clean fill facilities. Because we conclude that the legislature has expressly withdrawn the Village's power to act, we need not address the remaining three Anchor tests. The outstanding question is whether the Village's zoning ordinance and construction storm water and erosion regulations are "local approvals."

¶ 20. Wisconsin Stat. § 289.33(3)(d) defines "local approval" as follows:

any requirement for a permit, license, authorization, approval, variance or exception or any restriction, condition of approval or other restriction, regulation, requirement or prohibition imposed by a charter ordinance, general ordinance, zoning ordinance, resolution or regulation by a town, city, village, county or special purpose district....

Id. The definition then includes a lengthy, nonexhaus-tive list of enumerated statutory local approvals, among them, Wis. Stat. § 61.34 (police powers of the *295village board),15 Wis. Stat. §§ 62.23(7) and 61.35 (conferring zoning power to villages),16 and Wis. Stat. §61.354 (construction site erosion control and storm water management zoning).17 Sec. 289.33(3)(d).

¶ 21. The zoning ordinance here would seem to squarely fall within the more general stricture, "any requirement... or any restriction . . . imposed by a .. . zoning ordinance." See Wis. Stat. § 289.33(3)(d). And if there were any doubt, Wis. Stat. §§ 61.35 and 62.23, which confer zoning power to villages, are explicitly enumerated as local approvals as well. Because zoning requirements are expressly listed as local approvals in the statute, a clean fill facility like the one Scenic seeks to establish is exempt from any zoning requirements. End of story.

*296¶ 22. The Village's zoning argument never grapples with the language of Wis. Stat. § 289.33(3)(d) or Wis. Stat. §§ 61.35 and 62.23, nor does it squarely respond to these statutory arguments made by Scenic. Rather, it offers a doomsday scenario in response. According to the Village, Scenic's interpretation would allow a clean fill facility to be sited "literally anywhere" in Wisconsin subject to a few limited restrictions imposed by DNR. But as the DeRosso court noted, DNR has not allowed clean fill facilities to go completely unregulated. "Instead, the DNR has established an alternative regulatory scheme . . . designed to insure that the plaintiffs' facility does not compromise the integrity of the environment or the health of the City's residents." DeRosso, 200 Wis. 2d at 662. The court explained that clean fill facilities "must still conform with the requirements of Wis. Admin. Code § NR 504.04(3) and (4)." DeRosso, 200 Wis. 2d at 661.

¶[ 23. Among these requirements, a clean fill facility may not be operated within a floodplain. Wis. Admin. Code § NR 504.04(3)(c). These regulations also impose "performance standards" prohibiting the operation of a clean fill facility where it would have a "significant adverse impact on wetlands," cause a "take" of an endangered or threatened species, have a detrimental effect on surface water or groundwater quality, cause "migration and concentration of explosive gases" above certain limits, or emit "any hazardous air contaminant exceeding the limitations for those substances." Section NR 504.04(4)(a)-(f). Additionally, Wis. Admin. Code § NR 500.08(2) requires that all clean fill facilities "shall be operated and maintained in a nuisance-free and aesthetic manner."

¶ 24. These regulations make clear that the free-for-all scenario the Village paints is a tad overstated. *297DeRosso pointed out that DNR retains significant control over the siting of clean fill facilities through its regulations. Thus, we do not think interpreting Wis. Stat. § 289.43(8) as preempting local zoning leads to absurd results or is otherwise an irrational reading of the statute. Leaving the regulation of clean fill facilities to DNR may or may not be good policy, but it is what the legislature and DNR have done through statute and administrative rule (as interpreted by the supreme court). And that is what must dictate the outcome.

¶ 25. Finally, the parties dispute whether the storm water and erosion permitting requirements contained in the Village of Richfield Municipal Code §§ 167-8 and 167-23 are preempted.18 Sections 167-8 and 167-23 both concern preconstruction permits.19 Because the necessary permits were not obtained, the Village insists that the project cannot proceed. Wisconsin Stat. ch. 283 and Wis. Admin. Code § NR 216.07—the Village's asserted basis for sections 167-8 and 167-23 —are not specifically enumerated in the definition of *298"local approval." However, the definition indicates it is not limited to enumerated statutes. See Wis. Stat. § 289.33(3)(d) ("including without limitation because of enumeration"). Thus, we must look to the first part of the definition. Its exceptionally broad and inclusive language, in our view, fairly includes the Village's preconstruction storm water and erosion permitting requirements. A local approval includes "any requirement for a permit," "any restriction . . . regulation, requirement or prohibition imposed by a . . . general ordinance," and any "resolution or regulation by a . . . village." Id. Among the enumerated local approvals are general ordinances enacted by the village board pursuant to the village's police powers granted in Wis. Stat. § 61.34 and regulations regarding "Construction site erosion control and storm water management" under Wis. Stat. § 61.354, the same subject matter as the Village's regulations.

¶ 26. The Village responds that it is required by DNR to obtain its own municipal WPDES permit—a point source permit—for its municipal storm sewers. See Wis. Admin. Code § NR 216.02 (requiring "owners or operators of municipal separate storm sewer systems" to obtain a WPDES permit); Wis. Admin. Code § NR 216.01 (clarifying that municipal storm sewers are point sources under Wis. Stat. § 283.33). The Village declares that the requirements of this municipal WPDES permit (outlined in Wis. Admin. Code § NR 216.07) obligate the Village to maintain a "program to detect and remove illicit discharges . . . into the municipal separate storm sewer system" and a program to regulate storm water runoff from construction sites. The Village asserts that it complied with these obligations by enacting sections 167-8 and 167-23. The Village argues that interpreting Wis. Admin. Code § NR *299500.08 as exempting Scenic from compliance with the Village's own permitting process undermines its obligations under § NR 216.07.

¶ 27. Although the regulations governing the Village's WPDES permit are complex, the Village's argument is underdeveloped at best, and we need not address it at length. See State v. Pettit, 171 Wis. 2d 627, 646-47, 492 N.W.2d 633 (Ct. App. 1992) (explaining that we will not serve as advocate by developing a party's arguments for them). The Village does briefly explain the requirements of its municipal WPDES permit, but—as with its zoning argument—it fails to address the real issue: whether sections 167-8 and 167-23 are local approvals as defined in Wis. Stat. § 289.33(3)(d). Furthermore, the Village does not explain why Scenic's WPDES general permit—which provides coverage for Scenic's "construction site"— does not already satisfy the relevant DNR imposed requirements.20 Wisconsin Stat. § 283.35(1) provides that DNR may issue a general permit "[i]nstead of issuing a separate permit to an individual point source." The Village has not shown this to be a regulatory vacuum. Scenic must comply with the storm water and erosion requirements in its WPDES general permit as well as any other applicable DNR regulations going forward. Wisconsin Admin. Code § NR *300500.08 merely exempts Scenic from the Village's local preconstruction storm water and erosion permitting requirements expressed in sections 167-8 and 167-23. In short, the Village fails to muster any meaningful argument regarding the definition of local approvals or otherwise identify why its preconstruction storm water and erosion permitting requirements are not preempted.

f 28. We see no reason DNR cannot—through Wis. Admin. Code § NR 500.08—create an exception to its own regulations contained in Wis. Admin. Code § NR 216.07, and the Village makes no argument that DNR cannot do so.21 Indeed, DeRosso explained that § NR 500.08 was intended to do just that: create a blanket exemption from certain DNR regulations, including the requirement to comply with the local approvals (as defined) required to construct the facility. See DeRosso, 200 Wis. 2d at 663. Such a blanket exemption was intended to preempt all "exclusionary local regulations and ordinances." Id.

¶ 29. Given the sweeping definition of "local approvals," we conclude that the Village's zoning ordinance and construction storm water and erosion regulations are included. The zoning ordinance is expressly enumerated as a local approval, and the definition of "local approvals" is broad enough to include the Village's identified permitting requirements even though they are not expressly enumerated. The Village makes no real argument otherwise. Instead, the Village wishes us to focus on the policy consequences of the preemption analysis rather than the analysis itself. *301Our question is whether the zoning ordinance and construction storm water permitting requirements are "local approvals" as defined by statute; we conclude they are.

CONCLUSION

¶ 30. Wisconsin Stat. § 289.43 and Wis. Admin. Code § NR 500.08 have expressly withdrawn the Village's power to require clean fill facilities to comply with local approvals as defined in Wis. Stat. § 289.33(3)(d), among them, zoning and storm water and erosion permitting requirements. Accordingly, we reverse the circuit court's order granting summary judgment to the Village, and remand with directions that the circuit court grant Scenic's motion for partial summary judgment.22

By the Court.—Order reversed and cause remanded with directions.
