Annual Emissions Reports and Inventories

Yorke Engineering staff have managed emission reports throughout California since 1996, and now prepares more than 100 reports per year. Yorke staff are experts in the California Air Resources Board (CARB) and local Air District reporting rules and practices pertaining to emissions inventories and reports. Yorke staff have over 1,000 combined years of experience in quantifying toxic air contaminants (TACs) [diesel particulate matter (DPM), lead (Pb), polycyclic aromatic hydorcarbons, hexavalent chromium (Cr-VI), formaldehyde, benzene, toluene, xylenes, etc.], and criteria pollutants [volatile organic compounds (VOCs), nitrogen oxides (NOx), sulfur oxides (SOx), particulate matter (PM), and carbon monoxide (CO)]. We work closely with industrial and government clients to meet permitting or permit exemption requirements by using accurate and refined emission quantification.
