[1] This appeal is from a partial summary judgment, which dismissed part of the application of Kenneth M. Good Irrevocable Trust (Good) for a conditional water right. Summary judgment was granted because Good had not satisfied the requirements of section 37-92-302(2), 15 C.R.S. (1986 Supp.), to secure a hearing on the merits of his application for a conditional water right. Good failed to construct a well before its well permit expired, as required by section 37-92-302(2) to obtain a decree for a conditional water right. We affirm.
[3] Two well permits were issued by the state engineer on September 13, 1979. As required by section 37-92-302(2), Mulvihill supplemented his application with the well permits, which had an expiration date of September 13, 1980.2 Well one was *Page 49 completed before its permit expired; well two was never completed. No extension of the permit for well two was requested under section37-90-137(3)(a)(I), 15 C.R.S. (1986 Supp.), before the permit expired.
[4] Good acquired Mulvihill's interest in the wells and filed a motion in limine seeking to limit the issues at trial to whether there was an intent to appropriate water from both wells and an overt act establishing that intent. The Lewises moved for summary judgment asserting that Good had not fulfilled the requirements of section 37-92-302(2) since the well permits had expired before the hearing on Good's application.
[5] By order dated September 19, 1986, the water court granted Good's motion in limine with respect to well one and limited the proof required at the adjudication of that part of Good's application. The court, however, granted Lewises' motion for summary judgment concerning well two because the well had not been completed before its well permit expired. The water judge concluded that, under section 37-92-302(2), a valid well permit was a prerequisite to a hearing on the merits of the application for a conditional water right. The judge stated:
[6] "A reading [of] the statutes governing underground water and C.R.S.37-92-302 lead this Court to the conclusion that the legislative intent was to insure that appropriators of underground water complied with the provisions of C.R.S. 37-90-137 with regard to wells. That is, that appropriators made application for well permits and either had a well constructed pursuant to a permit or had an adverse ruling on the permit or no action on it within six months. In the latter two circumstances, the water Court was given the supervisory or appellate authority to require a permit to issue on the appropriate facts. In any case the actual well was intended to be constructed pursuant to a permit in existence at the time of construction. Here Cactus Valley Well Number One was so constructed. Cactus Valley Well Number Two was not and the permit to commence work has expired."
[7] The Lewises subsequently withdrew their opposition to the application and Good filed motions for reconsideration of the court's ruling with respect to well two. Good also sought a summary judgment that would grant its application for a conditional water right. By order dated March 12, 1987, the water court denied the motion for reconsideration and reaffirmed the earlier order. On April 2, 1987, the court entered a final order under C.R.C.P. 54(b) and Good appealed the court's dismissal of its application for a conditional right for well two. The conditional water right which related to the construction of well one is not at issue in this case.
[9] "shall [not] be heard on its merits by the referee or water judge until the application shall be supplemented by a permit or evidence of its denial by the state engineer pursuant to section 37-90-137 or evidence of the state engineer's failure to grant or deny such a permit within *Page 50 six months after application to the state engineer therefor."
[10] (Emphasis added.) Section 37-90-137(1), 15 C.R.S. (1986 Supp.), of the Management Act prohibits the drilling of new wells outside of a designated ground water basin unless the state engineer issues a permit to construct the well.4 See § 37-90-138(3), 15 C.R.S. (1973) (no well, requiring authority from the state engineer, shall be drilled without a well permit). The sole issue in determining if the Lewises' motion for summary judgment was properly granted is whether an unexpired well permit under section 37-90-137 was a prerequisite to a hearing on the merits of Good's application for a conditional water right on well two.
[11] Good claims that under the plain wording of section 37-92-302(2) an application for a conditional water right need only be supplemented by a well permit, whether valid or invalid, for the application to be heard on its merits. The water court's construction, according to Good, causes tributary ground water and surface water to have different appropriation requirements. Good asserts that such an interpretation frustrates the General Assembly's intent in the Administration Act to "integrate the appropriation, use, and administration of underground water tributary to a stream with the use of surface water," section 37-92-102(1)(a), 15 C.R.S. (1986 Supp.), by establishing a single system of water right appropriation and administration applicable to both tributary ground water and surface water. Specifically, Good contends that the water court's construction of section 37-92-302(2), which applies the time constraints for well permits under section 37-90-137(3)(a)(I), 15 C.R.S. (1986 Supp.), to applications for conditional water rights, is inconsistent with the four-year requirement under section 37-92-301(4) of establishing reasonable diligence,5 and defeats the purpose of the relation back doctrine.6 In our view, section 37-92-302(2) is ambiguous regarding the expiration date of the well permit that supplements an application for a conditional water right and is a prerequisite to a hearing on the application. After reviewing the text of the Administration Act and the Management Act and considering the intent of the General Assembly, we conclude that, when a permit is granted to drill *Page 51 a well for tributary ground water, an unexpired permit is a prerequisite to a hearing on the merits of an application for a conditional water right.
[12] Our primary task in construing a statute is to ascertain and effectuate the intent of the General Assembly. People v. District Court,713 P.2d 918 (Colo. 1986); Engelbrecht v. Hartford Accident Indem.Co., 680 P.2d 231 (Colo. 1984); § 2-4-203, 1B C.R.S. (1980). In determining the intent of the General Assembly, the entire act must be read and considered in context. Travelers Indem. Co. v. Barnes,191 Colo. 278, 552 P.2d 300 (1976); Humana, Inc. v. Board of Adjustment,189 Colo. 79, 537 P.2d 741 (1975). Separate acts of the General Assembly must be read together and construed to avoid inconsistencies. People v.James, 178 Colo. 401, 497 P.2d 1256 (1972); § 2-4-206, 1B C.R.S. (1980).
[13] Section 37-92-102(1)(a), the General Assembly's declaration of intent behind the Administration Act, provides that "it is the policy of this state to integrate the appropriation, use, and administration of underground water tributary to a stream with the use of surface water insuch a way as to maximize the beneficial use of all of the waters of thisstate." Although the Administration Act was intended to "integrate" the appropriation, use, and administration of underground water tributary to a stream with the use of surface water, it was not necessarily intended to administer surface water and tributary ground water in an identical manner. 1 G. Vranesh, Colorado Water Law 232 (1987) ("It is now well established that a modified form of prior appropriation governs the establishment and administration of ground water rights in Colorado."). Under the clear import of section 37-92-102(1)(a), ambiguities between the treatment of surface water and tributary ground water under the act must be construed to maximize the utilization of both tributary ground water and surface water. See Fellhauer v. People, 167 Colo. 320,447 P.2d 986 (1968) (rejecting argument that both surface water and tributary ground water must be administered in same fashion); G. Vranesh, supra, at 265 (discussing administration of surface water and ground water under Administration Act). Because the mechanics of appropriating ground water and surface water are not the same, different legal requirements may be required to realize the maximum utilization of both tributary ground water and surface water.7 See generally G. Vranesh, supra, at §§ 1.1, 3.5 (discussing physical properties of ground water and surface water).
[14] The General Assembly, in our view, intended an unexpired well permit to be a prerequisite under section 37-92-302(2) to a hearing on the merits of an application for a conditional water right. In State v. SouthwesternColorado Water Conservation District, 671 P.2d 1294 (Colo. 1983), we held that a claimant is not required to file a well permit prior to filing an application for a determination of a water right but may file the application to protect his priority date while an application for a well permit is pending before the state engineer. Under section 37-92-302(2), "[t]he water court is merely prohibited from entering a final decision on that application before the state engineer's decision is rendered or that official fails to grant or deny a permit within six months after application is made." Southwestern Colo. Water Conservation Dist.,671 P.2d at 1320.8 The application of *Page 52 the well permit requirements in section 37-90-137(3)(a)(I) to section37-92-302(2) of the Administration Act maximizes the use of tributary ground water by preventing speculation and hoarding of ground water, by encouraging the rapid completion of wells, and by preventing overappropriation of ground water resources.
[15] Section 37-90-137(3)(a)(I) establishes strict time constraints for the completion of wells utilizing tributary ground water. Under this section, a permit to construct a well outside a designated ground water basin, unless otherwise provided, expires one year after it is issued.9 The permit does not expire if the state engineer receives evidence that the water from the well was applied to a beneficial use. Id. It may be extended for one period of no longer than a year if, prior to its expiration, the applicant establishes good cause why the well was not completed and provides an estimate of the time necessary to complete the well. Id. If a well is not completed before the permit expires under section 37-90-137(3)(a)(I), another permit must be issued and a new priority date must be established. § 37-90-137(3)(c); see Town of De *Page 53 Beque v. Enewold, 199 Colo. 110, 606 P.2d 48 (1980) (unexcused failure to file an application for a quadrennial finding of reasonable diligence under section 37-92-301(4) mandates cancellation of the applicant's conditional rights). One purpose of the well permit requirement is to allow a well to be constructed under the supervision of the state engineer. § 37-90-138(1); Colorado Legislative Council, Report to theColorado General Assembly of 1969, at 6 (1968).
[16] The time limits in section 37-90-137(3)(a)(I), like those in section37-90-108(1)(a) and (2)(a), reflect the General Assembly's determination that wells, whether inside or outside a designated ground water basin, must be constructed and water placed to a beneficial use within one year, with a single extension of no more than one year upon a showing of good cause. Accordingly, the General Assembly has limited reasonable diligence for tributary and nontributary ground water to one year after a well permit is issued, and upon a showing of good cause why the well was not completed with an estimate of the time necessary to finish the well, an additional extension of time may be obtained for not in excess of one year. § 37-90-137(3)(a)(I); see supra note 9. These limitations afford ground water appropriators a reasonable opportunity to complete their appropriations while ensuring that the water is put to a beneficial use at the earliest possible time. The permit requirement, by avoiding delay in development, prevents the hoarding of ground water. See Rocky MountainPower Co. v. Colorado River Water Conservation Dist., 646 P.2d 383 (Colo. 1982) (conditional water decrees will not be granted to those who cannot show more than a speculative or conjectural future beneficial use).
[17] Requiring a valid well permit as a prerequisite under section37-92-302(2) to the hearing on the merits of an application for a conditional right also prevents overappropriation of ground water and injury to other appropriators.10 The state engineer is responsible for the administration and distribution of the waters of this state on the basis of priorities established by adjudicated decrees, the Colorado Constitution, statutory and case law, and written orders of the state engineer. §§ 37-92-301(1), -301(3), -501(1), 15 C.R.S. (1973 1986 Supp.); G. Vranesh, supra, at 509. Section 37-90-137(2) describes the duties of the state engineer in considering an application for a well to be drilled outside the boundaries of a designated ground water basin:
[18] "Upon receipt of an application for . . . a new, increased, or additional supply of ground water from an area outside the boundaries of a designated ground water basin . . . the state engineer shall make a determination as to whether or not the exercise of the requested permit will materially injure the vested water rights of others. If the state engineer finds that there is unappropriated water available for withdrawal by the proposed well and that the vested water rights of others will not be materially injured, and can be substantiated by hydrological and geological facts, he shall issue a permit to construct a well, but not otherwise; except that no permit shall be issued unless the location of the proposed well will be at a distance of more than six hundred feet from an existing well. . . ."
[19] The use which the water judge is to make of the state engineer's findings in *Page 54 evaluating a conditional water right application is set forth in section37-92-305(6), 15 C.R.S. (1986 Supp.). In the case of an application for a conditional water right that requires construction of a well, the referee or the water judge shall consider the findings of the state engineer under section 37-90-137. § 37-92-305(6). The state engineer's findings on material injury are supported by a presumption of validity.Danielson v. Jones, 698 P.2d 240 (Colo. 1985). The well permit requirement of section 37-92-302(2) "recognizes the special expertise of the state engineer with respect to wells and their effect on other water users by requiring that an applicant for a change of water right involving a new well apply for a well permit before seeking judicial approval of the change." Broyles v. Fort Lyon Canal Co., 638 P.2d 244, 250 (Colo. 1981).11
[20] Since Good's permit for well two expired before the application for a conditional water right was heard on its merits, the water court could not, under section 37-92-302(2), adjudicate the application. The petitioner's remaining arguments are without merit. Accordingly, the judgment of the water court is affirmed.
