(a) Notwithstanding any other law relating to the determination of the values upon which property taxes are based, values for each tax year from the 1984–85 tax year to the 2025–26 tax year, inclusive, for intercounty pipeline rights-of-way on publicly or privately owned property, including those rights-of-way that are the subject of a change in ownership, new construction, or any other reappraisable event during the period from March 1, 1975, to June 30, 2026, inclusive, shall be rebuttably presumed to be at full cash value for that year, if all of the following conditions are met:

1. (1)

   1. (A) The full cash value is determined to equal a 1975–76 base year value, annually adjusted for inflation in accordance with subdivision (b) of Section 2 of Article XIII A of the California Constitution, and the 1975–76 base year value was determined in accordance with the following schedule:

      1. (i) Twenty thousand dollars ($20,000) per mile for a high-density property.
      2. (ii) Twelve thousand dollars ($12,000) per mile for a transitional-density property.
      3. (iii) Nine thousand dollars ($9,000) per mile for a low-density property.

   2. (B) For purposes of this section, the density classifications described in subparagraph (A) are defined as follows:

      1. (i) “High density” means Category 1 (densely urban) as established by the State Board of Equalization.
      2. (ii) “Transitional density” means Category 2 (urban) as established by the State Board of Equalization.
      3. (iii) “Low density” means Category 3 (valley-agricultural), Category 4 (grazing), and Category 5 (mountain and desert) as established by the State Board of Equalization.
2. (2) The full cash value is determined utilizing the same property density classifications that were assigned to the property by the State Board of Equalization for the 1984–85 tax year or, if density classifications were not so assigned to the property for the 1984–85 tax year, the density classifications that were first assigned to the property by the board for a subsequent tax year.

3. (3)

   1. (A) If a taxpayer owns multiple pipelines in the same right-of-way, an additional 50 percent of the value attributed to the right-of-way for the presence of the first pipeline, as determined under paragraphs (1) and (2), shall be added for the presence of each additional pipeline up to a maximum of two additional pipelines. For any particular taxpayer, the total valuation for a multiple pipeline right-of-way shall not exceed 200 percent of the value determined for the right-of-way of the first pipeline in the right-of-way in accordance with paragraphs (1) and (2).
   2. (B) If the State Board of Equalization has determined that an intercounty pipeline, located within a multiple pipeline right-of-way previously valued in accordance with subparagraph (A), has been abandoned as a result of physical removal or blockage, the assessed value of the right-of-way attributable to the last pipeline enrolled in accordance with subparagraph (A) shall be reduced by not less than 75 percent of that increase in assessed value that resulted from the application of subparagraph (A).
4. (4) If all pipelines of a taxpayer located within the same pipeline right-of-way, previously valued in accordance with this section, are determined by the State Board of Equalization to have been abandoned as the result of physical removal or blockage, the assessed value of that right-of-way to that taxpayer shall be determined to be no more than 25 percent of the assessed value otherwise determined for the right-of-way for a single pipeline of that taxpayer pursuant to paragraphs (1) and (2).

(d) Notwithstanding any change in ownership, new construction, or decline in value occurring after March 1, 1975, if the assessor does not assign values for rights-of-way for any tax year from the 1984–85 tax year to the 2025–26 tax year, inclusive, at the 1975–76 base year values specified in subdivision (a), any assessed value that is determined on the basis of valuation standards that differ, in whole or in part, from those valuation standards set forth in subdivision (a) shall not benefit from any presumption of correctness, and the taxpayer may challenge the right to assess that property or the values for that property for that tax year. As used herein, a challenge to the right to assess shall include any assessment appeal, claim for refund, or lawsuit asserting any right, remedy, or cause of action relating to or arising from, but not limited to, the following or similar contentions:

1. (1) That the value of the right-of-way is included in the value of the underlying fee or railroad right-of-way.
2. (2) That assessment of the value of the right-of-way to the owner of the pipeline would result in double assessment.
3. (3) That the value of the right-of-way may not be assessed to the owner of the pipeline separately from the assessment of the value of the underlying fee.

(e) Notwithstanding any other provision of law, during a four-year period commencing on January 1, 1996, the assessor may issue an escape assessment in accordance with the specific valuation standards set forth in subdivision (a) for the following taxpayers and tax years:

1. (1) Any intercounty pipeline right-of-way taxpayer who was a plaintiff in Southern Pacific Pipe Lines, Inc. v. State Board of Equalization (1993) 14 Cal.App.4th 42, for the tax years 1984–85 to 1996–97, inclusive.
2. (2) Any intercounty pipeline right-of-way taxpayer who was not a plaintiff in Southern Pacific Pipe Lines, Inc. v. State Board of Equalization (1993) 14 Cal.App.4th 42, for the tax years 1989–90 to 1996–97, inclusive.
