Abstract : The U.S. Environmental Protection Agency regulates chromium air emissions generated from chromium electroplating and anodizing operations. The compliance deadline for hard chromium electroplating and anodizing is 25 January 1997. 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 (5) Discontinue operation. This study continues with pilot testing of a new technology, the Venturi/Vortex Closed Loop Scrubber, which may offer the potential for superior fume collection (while recycling emissions) at a significantly lower cost than current end-of-pipe control technologies.
