OPINION
{1} NMSA 1978, § 72-12-7(A) (1985) allows the owner of a “water right” to change the use of the water. Plaintiff Mabel Hanson had two permits to appropriate water but never put the water to beneficial use. When she filed applications to change the use from irrigation to subdivision use, the State Engineer denied her requests, reasoning that her failure to put the water to beneficial use meant that there was no “water right” to be changed. Plaintiff argues that a permit to appropriate water constitutes a “water right” that can be changed even if there has been no beneficial use. We agree with the State Engineer, and affirm.
BACKGROUND
{2} The State Engineer exercises administrative control over a particular groundwater basin by declaring it and defining its boundaries. NMSA 1978, § 72-12-1 (2003). Because the Estancia Basin is a declared basin, Plaintiff, who wished to appropriate water from this basin, had to apply for a permit to appropriate water. NMSA 1978, § 72-12-20 (1983); NMSA 1978, § 72-12-3 (2001). In determining whether to issue a permit, the State Engineer considers the applicant’s application and grants it if there are unappropriated waters or if the proposed appropriation would not impair existing water rights from the source, is not contrary to the conservation of water within the state, and is not detrimental to the public welfare of the state. § 72-12-3(A), (E).
{3} Plaintiff acquired two permits to appropriate water for irrigation purposes. Permit number E-4859 & S was issued by the State Engineer on March 20, 1989, and Permit number E-5340 was issued on January 23, 1992. Plaintiff drilled two wells, but it is undisputed she never put the water to beneficial use. Plaintiff later filed two applications, under Section 72-12-7(A), requesting a change to subdivision use. The State Engineer denied both applications because no water had been put to beneficial use.
{4} A State Engineer Hearing Officer agreed with these decisions, and the State Engineer adopted the Hearing Officer’s Report and Recommendation. Plaintiff appealed to the district court pursuant to NMSA 1978, § 72-7-1 (1971), which provides for a de novo appeal, and both parties moved for summary judgment. The court granted the State Engineer’s motion, and Plaintiff appeals.
DISCUSSION
Summary judgment is proper where there are no genuine issues of material fact and the movant is entitled to judgment as a matter of law. Self v. United Parcel Serv., Inc.,
A. Statutory Construction
{6} Section 72-12-7(A) states: “The owner of a water right may change the location of his well or change the use of the water, but only upon application to the state engineer.” This appeal requires us to decide the meaning of the term “water right,” as used in this section. Does it include a permit to appropriate water, even when no water has been put to beneficial use, as Plaintiff contends? Or does it require the perfection of a water right through beneficial use, as the State Engineer contends? While we agree that Plaintiff took the initial step to obtain a water right, and had a right to appropriate water, we are not persuaded that her permits alone establish that she is the owner of a “water right,” as that term is used in Section 72-12-7(A).
{7} Because this presents an issue of statutory construction, and whether summary judgment is proper, our review is de novo. See Rutherford v. Chaves County,
{8} We begin our analysis by recognizing that establishing a water right is a process that takes a period of time. See State ex rel. Reynolds v. Mendenhall,
{9} A water permit is an inchoate right, and “is the necessary first step” in obtaining a water right. See Green River Dev. Co. v. FMC Corp.,
{10} For more than a century, our law has been that a water right is perfected by the application of the water to beneficial use. See Holguin v. Elephant Butte Irrigation Dist.,
{11} We presume the legislature was aware of this significant body of water law when it enacted Section 72-12-7(A). See State ex rel. Citizens for Quality Educ. v. Gallagher,
{12} The legislature was aware of the distinction between holders of permits and owners of water rights, as shown by NMSA 1978, § 72-12-8 (2002), which provides that “the owner of a water right” or “the holder of a permit from the state engineer to appropriate any such waters” forfeits their right if the water is not applied to beneficial use. § 72-12-8(A); see also § 72-12-8(H) (distinguishing between the “holder of a valid water right” and a “permit to appropriate waters”). It is thus clear that if the legislature intended to treat permit holders the same as owners of water rights, it knew how to draft a statute which would successfully do so. The fact that the legislature did not do so, plus the absence of any reference to permit holders in Section 72-12-7(A), is compelling evidence that the legislature did not intend to allow permit holders who had not yet applied any water to beneficial use to be considered owners of a water right. See Citizens for Quality Educ.,
{13} Our conclusion is supported by Green River Dev. Co., in which the Wyoming Supreme Court interpreted a statute that allowed “an owner of a water right” to change its use or place of use. There, the Court considered whether a permit to appropriate water was a “water right” when the permit waters had never been put to beneficial use. The court held that a permit “is the necessary first step” in obtaining a water right, but that without an application to beneficial use, it was not a water right itself and therefore its use could not be changed. Id. at 348-51.
{14} Plaintiff relies heavily on Mendenhall,
{15} The Supreme Court reversed, holding that appellants should not be denied the benefit of their diligent efforts based solely on the State Engineer’s declaration of the lands as within a basin. Id. at 472-73,
{16} It is possible to read Mendenhall to suggest that, in a specific and limited circumstance, an appropriator may have an enforceable water right at some time before the water has been put to beneficial use. However, we disagree that it governs the outcome here. Mendenhall deals with the effect of the State Engineer’s declaration of a basin during the period in which the appropriator was diligently engaged in the preparations to apply the water to beneficial use. Mendenhall does not address whether a permit is a “water right,” and does not address the precise issue here. Distinguishable on its facts and underlying rationale, Mendenhall does not stand for the proposition that a permit is the same as a water right.
{17} Plaintiff also relies on Clodfelter v. Reynolds,
B. Due Process
1. Estoppel
{18} Plaintiff argues that the State Engineer is estopped from denying her applications to change use because an earlier, similar request of hers had been granted, and because some requests by other people to change use had been granted even though they had not applied the water to beneficial use.
{19} Courts are reluctant to apply equitable estoppel against a governmental entity. Gallegos v. Pueblo of Tesuque,
A party seeking to establish estoppel against the government must establish that
(1) the government knew the facts; (2) the government intended its conduct to be acted upon or so acted that plaintiffs had the right to believe it was so intended; (3) plaintiffs must have been ignorant of the true facts; and (4) plaintiffs reasonably relied on the government’s conduct to their injury.
Gallegos,
{20} One of Plaintiffs arguments about why summary judgment should not have been granted in the State Engineer’s favor is that there was a disputed factual issue concerning whether the State Engineer had a longstanding policy in the Estancia Basin of allowing a change of use only if the water had been put to beneficial use. The record discloses conflicting evidence on this point. The record also demonstrates that, whatever the State Engineer’s policy may have been, it was not consistently applied. Some requests to change use were denied because there had been no beneficial use, while others were granted even though there was apparently no beneficial use. From this, Plaintiff argues that the State Engineer is estopped to deny her request.
{21} This does not meet the requirements of estoppel against the State. Less than perfect consistency may be caused by mistakes by employees or supervisors, by changes in policy, or by changes in the agency’s interpretation of its governing statutes. This case appears to present a mixture of all these reasons. Under Plaintiffs view, once the State Engineer granted some requests to change use without prior application to beneficial use, then he could never reevaluate or change his position. Estoppel against the government would then be the rule, not the exception. Here, we have held that the State Engineer’s interpretation of Section 72-12-7(A) is correct. The fact that an agency overlooked a particular requirement in one case does not estop it from enforcing the requirements in another case. See Erickson,
{22} Plaintiff also supports her estoppel argument claiming that “later preferential treatment [was] given to a similar application by the sitting Governor’s son.” Plaintiff also suggests that the application was “identical.” However, the footnote in the record, on which she relies, does not establish that the application was identical or similar. Nothing in the footnote establishes that the “Governor’s son” was allowed a transfer without establishing prior beneficial use. Consequently, we cannot say the application was “similar',” except for the fact that it involved an application to change use. The footnote only establishes that the transfer application was ruled on within three months, much more quickly than Plaintiffs requests. Any discrepancy in the time it took to process applications does not establish a due process violation, nor does it require us to hold that the State Engineer must grant her applications.
{23} Plaintiff does not assert that the State Engineer made any affirmative misrepresentation, or establish that she relied to her detriment on any such misrepresentation. Rather, her argument is simply that the State Engineer did not have a consistent policy. Plaintiff has not established a shocking degree of aggravated and overreaching conduct or meet the requirements for estoppel against the state. Absent any showing on these elements, it was proper for the district court not to apply estoppel.
2. Stay of Discovery
{24} Plaintiff claims that she was denied due process because the district court granted the State Engineer’s motion to stay discovery. We review an order limiting discovery for an abuse of discretion. See Doe v. Roman Catholic Diocese of Boise, Inc.,
{25} It appears from the record that Plaintiff had specific information supporting her position, and was able to present her argument about differing treatment to the trial court. More discovery might have turned up more instances where prior beneficial use was not required. However, as we have discussed, Plaintiff fails to persuade us that less than consistent treatment of applications to change use establishes estoppel. As we have also discussed, estoppel rarely applies against the State, and public policy strongly discourages the application of estoppel against the State Engineer where the waters of the State are involved. Gallegos,
3. Delay
{26} Plaintiff suggests that a lengthy delay by the State Engineer and the court system in dealing with her applications denied her due process. Plaintiff complains that it took five years for the State Engineer to deny her applications, and another three years for the district court to decide her appeal. We share Plaintiffs concern that an administrative agency would take five years to deny a relatively simple application. However, Plaintiff has cited no authority for the proposition that delay alone would constitute a due process violation entitling her to have her applications granted. See In re Adoption of Doe,
{27} We are also concerned about the three year delay in the district court, but the record reflects no pleading filed by Plaintiff that would have called the district court’s attention to the problem. Additionally, we reject this claim because we are unaware of any authority, and Plaintiff has cited us to none, holding that inordinate delay by the district court would entitle her to the relief she sought on the merits. Id.
4.Prior Notice
{28} Plaintiff makes a brief, unclear argument contending that denying her applications without prior notice violated due process. We decline to address this argument. See Santistevan v. Centinel Bank of Taos,
{29} For these reasons, the order of the district court is affirmed.
{30} IT IS SO ORDERED.
