Introduction

The case of Tesoro Refining and Marketing Company v. The Department of Revenue ([190 P.3d 28](https://cite.case.law/wash-courts/190-p3d-28/)) presented before the Supreme Court of Washington on August 14, 2008, addresses the applicability of the Hazardous Substance Tax (HST) to refinery gas utilized within a refinery for heating purposes. Tesoro Refining and Marketing Company (Tesoro) sought a refund for the HST paid on refinery gas, arguing for an exemption based on its internal use. The central issue revolves around whether Tesoro's use of refinery gas constitutes taxable possession under Washington's HST statutes.

Summary of the Judgment

The Supreme Court of Washington affirmed the decision of the Court of Appeals, holding that Tesoro's use of refinery gas as a heat source within its Anacortes refinery constitutes a taxable possession under RCW 82.21.030, the Hazardous Substance Tax. The court determined that Tesoro did not qualify for an exemption under WAC 458-20-252(7)(b), as the refinery gas was not integrated into another product but was instead used independently for heating. Consequently, Tesoro was required to pay the HST on the refinery gas used internally.

Analysis

Precedents Cited

The judgment references several key precedents that influenced the court's decision:

• Simpson Investment Co. v. Department of Revenue - Established de novo review for legal conclusions in tax refund cases.
• BURNS v. CITY OF SEATTLE - Emphasized the primary role of legislative intent in statutory interpretation.
• STATE v. KELLER - Discussed the substitution of "and" for "or" in statutory language to reflect legislative intent.
• MADER v. HEALTH CARE AUTH. - Affirmed that agency regulations must align with statutes and cannot create extra-statutory exemptions.

These precedents collectively guided the court in interpreting the HST statutes and assessing the applicability of tax exemptions.

Legal Reasoning

The court's legal reasoning centered on the interpretation of key terms within the HST statutes, particularly "possession" and "control." Under RCW 82.21.030, possession encompasses both actual and constructive control over a hazardous substance, defined as the power to sell or use the substance. Tesoro argued that since it only used the refinery gas for heating and did not sell it, it should be exempt from the HST under Rule 252-20-252(7)(b).

However, the court rejected this argument by emphasizing the plain language of the statute. The use of "or" in the definition of "control" was interpreted disjunctively, meaning that having either the power to sell or the power to use the substance sufficed for possession. The court found no ambiguity in this language and, therefore, Tesoro's internal use of the refinery gas did not exempt it from the HST. Additionally, the court highlighted that the refinery gas was not integrated into another product, which further negated Tesoro's claim for exemption.

Impact

This judgment solidifies the interpretation of "possession" under Washington's HST, making it clear that internal use of hazardous substances for operational purposes does not exempt entities from taxation. Future cases involving the HST will rely on this precedent to determine taxable possession, ensuring consistency in the application of tax laws related to hazardous substances. Moreover, the decision underscores the court's commitment to adhering to the plain language of statutes over agency interpretations or outdated regulations.

Complex Concepts Simplified

Hazardous Substance Tax (HST)

The HST is a state-imposed tax on the possession of hazardous substances within Washington. It aims to fund environmental cleanup programs by taxing entities that handle or control substances deemed hazardous.

Possession and Control

Possession: Under RCW 82.21.020(3), possession refers to both actual and constructive control over a hazardous substance. Actual possession involves physical holding, while constructive possession involves having the authority to manage or utilize the substance.

Control: Defined as the power to sell or use a hazardous substance or to authorize its sale or use by another party. The presence of either power qualifies as control, thereby establishing possession for tax purposes.

Rule 252-20-252(7)(b)

This regulatory rule provides exemptions to the HST when a hazardous substance is consumed during the manufacturing or processing activity or becomes a component of the product being manufactured. The exemption aims to prevent double taxation of substances that are integral to production processes.

Conclusion

The Supreme Court of Washington's decision in Tesoro Refining and Marketing Company v. The Department of Revenue firmly establishes that the internal use of refinery gas as a heat source within a refinery constitutes taxable possession under the Hazardous Substance Tax. By adhering to the plain language of the statute and rejecting ambiguous interpretations, the court ensures clarity and consistency in the application of environmental tax laws. This judgment not only affects Tesoro but sets a clear precedent for how similar cases will be adjudicated in the future, emphasizing the importance of statutory language in determining tax liabilities.

Additional Notes

The judgment included concurring and dissenting opinions, highlighting different interpretations of the statute's intent. While the majority focused on the clear language of the statute, dissenting opinions emphasized the legislative intent to target polluters specifically. Despite differing viewpoints, the majority's decision reinforces the authority of statutory language over regulatory interpretations, ensuring that tax obligations are clearly defined and enforceable.
