Plain English Breakdown

The candidate explanation included claims about the bill affecting all pollution control facilities, which is unsupported by the official summary and text. The bill focuses solely on clarifying that facilities constructed for capturing nonpoint source carbon dioxide do not qualify for property tax exemptions.

Clarifying Property Tax Exemption for Pollution Control

This law changes how property used to control pollution is taxed, making it clear that facilities built only to capture nonpoint source carbon dioxide do not get tax breaks.

What This Bill Does

  • Amends the Wyoming Environmental Quality Act to clarify that facilities constructed solely for capturing nonpoint source carbon dioxide are not exempt from ad valorem property taxation.
  • Requires the Department of Revenue to create rules for implementing this change.

Who It Names or Affects

  • Property owners who have facilities designed, installed and utilized primarily for eliminating, controlling or preventing air, water or land pollution.
  • The Wyoming Department of Revenue and county assessors responsible for determining property tax exemptions.

Terms To Know

ad valorem taxation
A type of tax based on the value of a property or item.
nonpoint source carbon dioxide
Carbon dioxide that comes from many different sources, not just one specific place.

Limits and Unknowns

  • The law only affects facilities built specifically to capture nonpoint source carbon dioxide.
  • It does not change how other pollution control facilities are taxed.
