Volume 3 - Area Sources and 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air emissions data with targeted quality objectives using cost effective approaches, but in some cases have become outdated.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 3 – Area Sources and Area Source Method Abstracts” provides a complete reference for both the general case of nonpoint source emissions (Chapter 1) as well as for 16 specific cases (Chapters 2-9, and 11-18) for a variety of source types often included as nonpoint source emissions in inventories.  In addition, Volume 3a provides additional information on ammonia emissions from various source types, and Volume 3b provide abstracts on seven additional categories.  The chapters include nonpoint source guidance on planning, emissions estimation, data collection, inventory documentation and reporting, and quality assurance/quality control.
