Atmospheric Deposition comprises only about 15% of the FSP loading, but the bulk of the total nitrogen loading to the Lake. The strategy for reducing FSP and phosphorus from atmospheric deposition calls for actions and controls that reduce dust from roadways,  parking lots, and construction sites, such as street  sweeping with advanced equipment, or paving or eliminating dirt roads. The strategy for reducing nitrogen generated in-basin as emissions relies on the Tahoe Regional Planning Agency’s (TRPA) 2012 air quality and transportation management plan, which aims to reduce vehicle miles travelled in the Tahoe Basin. Several Environmental Improvement Project (EIP) PMs are closley aligned with the goal of achieving load reductions in the Atmospheric Deposition Source Category.
