This Foundry Emissions Protocol document is intended to provide guidance and instructions to iron and steel foundry owners and operators for the purpose of improving emission inventories, and emission reporting in general, by source owners and operators. This document presents a hierarchy of emission measurement or estimation methods for various foundry emission sources and provides a listing of pollutants that may be emitted by each source type. This document may also be used by other entities, such as federal, state, and local agencies, for consistency in estimating emissions from iron and steel foundries.
This Foundry Emissions Protocol document provides methods for estimating criteria pollutant and hazardous air pollutant (HAP) emissions from foundry operations. Methodologies for estimating emissions of greenhouse gases (GHG) are not included in this Foundry Emissions Protocol document. Methodologies for estimating emissions of GHG are provided in the Mandatory Greenhouse Gas Emissions Reporting Rule (Final Rule, 74 Federal Register [FR] 56260) for selected foundry processes
