Draft Environmental Assessment for Proposed Rule 1407.1 – Control of Toxic Air Contaminant Emissions From Chromium Alloy Melting Operations
Document Type
EA - Environmental Assessment
Received
Project Applicant
South Coast AQMD

Document Description
PR 1407.1 proposes to reduce hexavalent chromium, arsenic, cadmium, and nickel emissions from melting operations of metals containing greater than 0.5 percent chromium, including, but not limited to, alloy steel, chromium non-ferrous alloys, stainless steel, and superalloys. Chromium alloy melting operations include smelting, die-casting, and other miscellaneous processes where metals are processed in molten form. PR 1407.1 establishes collection efficiency requirements and hexavalent chromium mass emission limits to control point source emissions; housekeeping requirements and building enclosure provisions to limit fugitive emissions; and source testing, material testing, parameter monitoring, and recordkeeping requirements. By focusing on controlling hexavalent chromium emissions from chromium alloy melting operations, concurrent emission reductions of arsenic, cadmium, and nickel are also expected. The Draft EA did not identify any environmental topic areas that would be significantly adversely affected by PR 1407.1. Two facilities affected by PR 1407.1 were identified on lists compiled by the California Department of Toxic Substances Control per Government Code Section 65962.5.
