The point source inventory is the collection of emissions generated from sources that have a valid permit to operate with the District. Data on the source’s annual usage rates and operation schedule are collected from each facility annually through the emission survey process and used to estimate the facility’s point source emissions. The District’s Technical Services Division collects and maintains this emission information in a database for each point source that submits data. Currently, the District’s point source emissions database contains emission information for more than 9,000 facilities located throughout the San Joaquin Valley, which is reported to CARB annually so it can be included in their CEIDARS database.
Please note, to designate emission data submittal information as confidential, please forward the completed "Request for Confidential Classification of Source Data" (PDF or MS Word) to the District. It will be determined whether the information can be classified as confidential under District Rule 1030.
Criteria Air Pollutant and Toxics Air Contaminants
In 2018, CARB developed a uniform statewide system of annual reporting of criteria air pollutant and toxic air contaminant emissions for certain categories of stationary sources as required under Reporting Regulation AB 617. The bill requires stationary sources to report their annual emissions of criteria air pollutants and toxic air contaminants. In order to implement these reporting requirements, CARB developed the "Regulation for the Reporting of Criteria Air Pollutants and Toxic Air Contaminants" (CTR) to implement statewide annual reporting of this emission data from facilities. The District is implementing this regulation on behalf of the state through the District’s existing annual emission inventory and air toxics processes. The additional emissions inventory data collected from CTR is critical to understanding the sources of emissions that may contribute to adverse health risks or other impacts at the local, regional, and statewide level.
