| Abstract |
In order to support the implementation of the 2008 Lead National Ambient Air Quality Standards (NAAQS), this document contains an analysis of air control measures for the purpose of determining what controls may constitute reasonably available control measures (RACM), including reasonably available control technologies (RACT), for controlling lead emissions pursuant to Section 172(c)(1) of the Clean Air Act (CAA). This document was prepared pursuant to EPA Contract EP-D-07-001, Work Assignment No. 4-10, by EC/R Incorporated. This document identifies control measures used to control lead emissions from sources in the Secondary Lead Smelting, Lead Acid Battery Manufacturing, Iron and Steel Mills, and Iron and Steel Foundries source categories. For each identified control measure, this document contains a RACM criteria assessment to determine how likely each control measure is to constitute RACM. In addition, for the Primary Lead Smelting, Secondary Aluminum Production, Secondary Copper Smelting, Mining, and Petroleum Refineries source categories, data relevant to a RACM determination was collected from EPA's CoST database and is presented here for a RACM criteria assessment. A prior EPA document identifies potential RACM for controlling lead emissions. This document, 'Implementation of the 2008 Lead National Ambient Air Quality Standards (NAAQS): Guide to Developing Reasonably Available Control Measures (RACM) for Controlling Lead Emissions,' is intended to replace such prior document, and any other EPA-issued document, with respect to identifying RACM for controlling lead emissions. |
