The county Board of Supervisors, functioning as the county Air Pollution Control District board, has scheduled a special meeting for Tuesday to decide how to challenge a permit issued for transmission lines connecting power plants in Mexicali to the California power grid.
The proposed transmission lines will cross into the southern part of Imperial County and will import electricity from Boston-based Intergen Aztec Energy's La Rosita plant and San Diego-based Sempra Energy Resources' Termoelectrica de Mexicali plant.
The Air Pollution Control District estimates Sempra's and Intergen's turbines will produce 3,367 tons of nitrogen oxide per year.
According to the U.S. Environmental Protection Agency, nitrogen oxide is a major contributor to ground-level ozone and nitrate particles, leading to serious respiratory problems.
The presidential permit for the transmission lines was issued two weeks ago.
In other business at its regular meeting Tuesday, the Board of Supervisors is scheduled to approve an increase of $360,700 to the Workforce Investment Board's welfare-to-work budget.
