Abatement of Hazardous Air Pollutant Emissions from Army Chromium Electroplatingand Anodizing Operations

摘要

The U.S. Environmental Protection Agency regulates chromium air emissionsgenerated from chromium electroplating and anodizing operations. Currently eight Army installations have either hard chromium electroplating and/or anodizing operations, which must meet applicable regulations. The overall objective this project is to develop control technologies to control hazardous air emissions from Army chromium electroplating and anodizing operations. This initial part of the study: (1) investigated the current status of Army compliance, (2) summarized available technologies and practices to control chromium emissions, and (3) made recommendations regarding technologies to help Army installations achieve compliance. Five basic options are available to chromium electroplaters and anodizing facilities to meet compliance limits: (1) Install new air pollution control equipment; (2) Renew or adjust existing control devices; (3) Use emission reduction practices at tank; (4) Replace the current production process; and (5) Discontinue operation.
