AZ HB2564

Adds pipes and valves four inches or larger used to transport oil, natural gas, artificial gas, water, or coal slurry as tax-exempt property under the retail and use tax classifications, including related compressor units, regulators, machinery, equipment, fittings, and seals.

Renumbers subsequent exemptions in sections 42-5061, 42-5159, and related statutes to accommodate the new pipes and valves exemption, shifting paragraph numbers throughout these sections.

Updates cross-references in section 43-1082 (income tax credits for construction materials) to reflect the renumbered exemptions for direct broadcast satellite television facilities.

Requires two-thirds affirmative vote in both houses of the legislature for passage and immediate effectiveness upon gubernatorial signature or three-fourths vote override.
