Program Air Quality
Approach
TRPA and its partners monitor five air quality constituents (ozone, carbon monoxide, particulate matter 2.5, particualte matter 10, oxides of nitrogen) at six air quality stations located around the Lake Tahoe Basin. All air quality monitoring is conducted according to strict EPA-standards or EPA-approved equivelant methods. The six air quality stations are operated and funded by a variety of federal, state, local, and educational partners.
