Air Quality and Transportation

Air quality and transportation is one of the four focal areas in the EIP. The Tahoe Regional Planning Agency (TRPA) 2006 Threshold Evaluation found that the Tahoe basin was not attaining standards for carbon monoxide, ozone, and particulates. These pollutants pose threats to human health. Air deposition of nitrogen, phosphorous, and fine sediment contribute to pollution of Lake Tahoe.

Research under this topic includes sampling, modeling, and demonstration projects to control airborne particulate matter and other pollutants that may reduce clarity of Lake Tahoe or otherwise affect ecological values and human health within the basin. Research on air quality has a particular focus on transportation, as vehicle travel along roadways is an important source of air pollutants. The TRPA is planning to develop basin-scale monitoring plans for particulate matter, ozone and its precursors, and vehicle congestion and distances traveled.
