7.9 Reciprocating Engines - Excessive Use
Category 1598
7.9.1 Introduction
Category 1598 accounts for criteria pollutant emissions (particulate, organic, NOx, SOx, and CO) from the excess use of internal combustion reciprocating engines that use liquid fuels that are used to power emergency electric generators. Category 1598 was added to the emissions inventory to account for additional emissions due to the increased use of emergency generators during the electric power shortage crisis in California (2001-2002). Unlike category 304, which accounts for emissions from normal usage of standby generators, Category 1598 accounts for emissions due to excessive use of these generators only, and currently only for years 2001-02.
Emissions in this category are predicted to increase due to the increased use of standby engines during power shutdowns caused by wildfires. However, data on affected areas is not readily available. Due to this lack of detailed electric generator operational data, it is difficult to estimate emissions for this category. It has been decided that Category 1598 emissions inventory update will be deferred until the next iteration of inventory updates when more information becomes available.
7.9.2 Methodology
Emissions due to increased emergency generator usage were estimated to be negligible during the electric power shortage crisis in California (2001-2002).
