This Indicator is reported in the following LT Info areas:
Status
Annual estimated nitrogen oxide emissions (tons/day) for the California portion of the Lake Tahoe Region. While the TRPA 1982 Threshold Study Report estimated 1981 NOx daily emissions to be 9.4 tons, CARB estimated 1980 levels to be 5.6 tons/day (red line). Because consistent CARB data exists, CARB estimates are used as the threshold standard. Source: CARB (2015) emission inventory for the California portion of the Lake Tahoe Air Basin and TRPA. NOx concentrations as measured at the newly established TRPA Stateline monitoring location. While no official TRPA standards exist for NOx concentrations, this data is used to evaluate NOx concentrations against CA and Federal standards. Source: TRPA

Program Oxides of Nitrogen Emissions Monitoring

Approach

CARB compiles data to create the criteria pollutant emission inventory, which includes information on the emissions of reactive organic gases (ROG), oxides of nitrogen (NOx), oxides of sulfur (SOx), carbon monoxide (CO), and particulate matter (PM10). Data are gathered continuously and stored in the California Emission Inventory Development and Reporting System (CEIDARS). A summary of the criteria pollutant inventory is published annually.

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.
