Air Emissions Inventories

Volume 3b - Area Source Method Abstracts

This document provides technical documentation of nonpoint (area) source emissions estimation as a part of the ten volumes of the Emissions Inventory Improvement Program (EIIP) materials. These volumes provide standard procedures for calculating air emissions data with targeted quality objectives using cost effective approaches, but in some cases have become outdated.

“Volume 3b – Area Source Method Abstracts” provides a reference for seven additional categories that are not covered in Volumes 3 or 3a. These abstracts are less extensive than the chapters included in the main Volume, but provide a concise reference for asphalt roofing kettles, bakeries, remediation of leaking underground storage tanks, vehicle fires, and residential and commercial/institutional combustion of coal, fuel oil, kerosene, natural gas, and liquefied petroleum gas.
