JOHNSON, Justice.

Western Gas Resources, Inc. Western, appeals from a district court judgment affirming a tax assessment by the North Dakota Tax Commissioner Commissioner under Chapter 57-51.1, N.D.C.C., the Oil Extraction Tax OET. We affirm.

Section 57-51.1-02, N.D.C.C., imposes an " `oil extraction tax', upon the activity in this state of extracting oil from the earth." For purposes of the OET, Section 57-51.1-01(3) defines "oil" as "petroleum, crude oil, mineral oil, casinghead gasoline, and all liquid hydrocarbons that are recovered from gas on the lease incidental to the production of the gas." The principal issue in this appeal is whether "field condensate" is "oil" as defined by Section 57-51.1-01(3), N.D.C.C. Our analysis of this issue requires a description of "field condensate" and how Western recovers "field condensate" from natural gas.

Western is a gas processing company which owns and operates a natural gas gathering system and a natural gas processing facility in Billings County. Western purchases natural gas from various oil and gas producers and moves the gas through its gathering system to its processing facility at the Teddy Roosevelt Gas Plant TR Plant. At the well sites, the producers pump a mixture of oil, gas, and water from wells and separate the mixture into oil, gas, and water phases with a separator or heater treater. The producers dispose of the water, retain the oil, and pipe the gas stream in a vapor form to a "custody transfer meter" where custody and ownership is transferred to Western for movement through its gathering system to its processing facility at the TR Plant.

As the gas stream moves through Western's gathering system, changes in pressure and temperature cause liquid hydrocarbons to condense in the pipeline. The liquid hydrocarbons are called "drips" or "field condensate" and are collected and stored in underground tanks called "drip locations." In addition to the "drip locations," Western also recovers field condensate at field compressor stations, where the gas is compressed in three separate stages to facilitate its movement to the TR Plant. Western sells all the "field condensate" at a crude oil price and puts it in a crude oil pipeline.

After compressing the gas at the compressor stations, Western pipes the gas to an inlet receiver or scrubber at the TR Plant. After the gas passes through the inlet receiver, Western processes the gas and additional liquids are recovered. The liquids recovered at the TR Plant are referred to as "plant condensate." Field condensate is recovered in Western's gathering system before the inlet receiver at the TR Plant and plant condensate is recovered after the inlet receiver.

On October 18, 1985, the Commissioner assessed an OET against Western for field and plant condensate recovered from January 1981 through December 1983. The Commissioner subsequently abated the assessment for plant condensate and also agreed to Western's valuation of the field condensate for determining the amount of OET. Western objected to the assessment for field condensate, contending that field condensate was produced after the custody transfer meter and was therefore not recovered "on the lease" as required by the definition of "oil" in Section 57-51.1-01(3), N.D.C.C.

An administrative hearing officer determined that field condensate was "oil" under Section 57-51.1-01(3), N.D.C.C. The hearing officer construed "all liquid hydrocarbons that are recovered from gas on the lease" to mean liquid hydrocarbons recovered in Western's gathering system before the inlet receiver at the TR Plant. The hearing officer recommended that Western be assessed an OET of $129,483.71. The Commissioner substantially adopted the hearing officer's findings of fact, conclusions of law, and recommendation. However, under Section 57-51-10, N.D.C.C., the Commissioner found good cause for waiving one hundred percent of the penalty and twenty percent of the interest on the OET. The Commissioner thus ordered Western to pay an OET of $129,483.71 plus eighty percent of the interest.¹ The district court affirmed the Commissioner's decision, and Western appealed.

Section 28-32-19, N.D.C.C., governs our review of decisions by an administrative agency. We affirm an agency decision unless its findings of fact are not supported by a preponderance of evidence, its conclusions of law are not supported by its findings of fact, its decision is not supported by its conclusions of law, or its decision is not in accordance with the law. Section 28-32-19, N.D.C.C.; Schiff v. North Dakota Workers Compensation Bureau, 480 N.W.2d 732 (N.D.1992).

Western argues that field condensate is not "oil" as defined by Section 57-51.1-01(3), N.D.C.C., because it is not recovered "on the lease." Western asserts that "on the lease" means facilities ending with the custody transfer meter. Western contends that its processing plant begins at the custody transfer meter and therefore field condensate is produced at its processing plant and not "on the lease." The Commissioner responds that "on the lease" means facilities ending with the inlet receiver at the TR Plant. The Commissioner thus argues field condensate is a liquid hydrocarbon that is recovered from gas "on the lease" because it is recovered before the inlet receiver at the TR Plant.

The interpretation of a statute is a question of law and is fully reviewable by this court. Rocky Mountain Oil & Gas Ass'n. v. Conrad, 405 N.W.2d 279 (N.D.1987). In construing statutes, our primary objective is to ascertain the intent of the Legislature. Id. The Legislature's intent must be sought initially from the language of the statute. Peterson v. Heitkamp, 442 N.W.2d 219 (N.D.1989). If the language of a statute is clear and unambiguous, we cannot ignore that language under the pretext of pursuing its spirit because the legislative intent is presumed clear from the face of the statute. County of Stutsman v. State Historical Society, 371 N.W.2d 321 (N.D.1985); Section 1-02-05, N.D.C.C. However, if the language of a statute is ambiguous, the court may resort to extrinsic aids to interpret the statute. County of Stutsman, supra. A statute is ambiguous if it is susceptible to differing but rational meanings. Rott v. Connecticut General Life Ins. Co., 478 N.W.2d 570 (N.D.1991).

In this case, the definition of oil, particularly the extent and meaning of the "on the lease" modifier, is susceptible to different meanings. Both parties have presented rational interpretations of that language. We therefore conclude that the definition of "oil" in Section 57-51.1-01(3), N.D.C.C., is ambiguous.

Section 1-02-39, N.D.C.C., describes extrinsic aids which may be used to ascertain legislative intent when a statute is ambiguous. These include:

"1. The object sought to be attained.

"2. The circumstances under which the statute was enacted.

"3. The legislative history.

"4. The common law or former statutory provisions, including laws upon the same or similar subjects.

"5. The consequences of a particular construction.

"6. The administrative construction of the statute.

"7. The preamble."

The Commissioner construed "on the lease" to include all facilities prior to the inlet receiver to the TR Plant. The Commissioner thus concluded that field condensate was oil under the OET. The administrative construction of a statute by the agency administering the law is entitled to deference if that interpretation does not contradict clear and unambiguous statutory language. Rocky Mountain Oil & Gas Ass'n., supra; Stutsman County, supra; see Section 1-02-39(6), N.D.C.C. Administrative deference is an important consideration when an agency interprets and implements a law that is complex and technical. True v. Heitkamp, 470 N.W.2d 582 (N.D.1991). Here, the Commissioner's interpretation is especially persuasive and entitled to deference because of the complex and technical nature of the OET and because that interpretation comports with the language of the statute and the legislative history. See Section 1-02-39(3), N.D.C.C.

The OET was originally approved by the voters as an initiated measure on November 4, 1980. 1981 N.D.Sess. Laws ch. 649. As originally approved, the OET defined "oil" as "petroleum, crude oil, mineral oil, casinghead gasoline, and all liquid hydrocarbons that are recovered from gas by means of a separator, or by other nonmechanical methods, incidental to the production of the gas." Id. at § 4. The 1981 Legislature changed "by means of a separator, or by other nonmechanical methods" to "on the lease." 1981 N.D.Sess.Laws ch. 612, § 2.

The legislative history for that change indicates that representatives from the oil and gas industry initially requested the same definition of oil for both the OET and the Gross Production Tax GPT, Ch. 57-51, N.D.C.C.² March 9, 1981 Minutes of Senate Finance and Taxation Committee regarding HB 1651. However, representatives from the Tax Department requested a broader definition of oil under the OET to ensure that liquid hydrocarbons like light crude were taxable. Id.; March 11, 1981 Minutes of Senate Finance and Taxation Committee regarding HB 1651; see also March 20, 1981 Conference Committee regarding HB 1651. In explaining why members of the oil and gas industry wanted the same definition of oil for both the OET and the GPT, counsel for the Tax Department said that members of the industry...
