## Summary

ChromeTech owns and operates a plating facility where it conducts, among other things, hard-chromium electroplating of mostly ferrous materials.  The facility has four hexavalent chromium-electroplating tanks that are subject to Subpart N.  Each tank is equipped with a multi-stage composite mesh-pad (CMP) system for controlling emissions, and each system is equipped with a gauge that measures the overall pressure drop across the system, in addition to gauges that measure the pressure drop across each individual stage.  On September 2, 2014, EPA issued to ChromeTech a Finding of Violation alleging that it failed to 1) adequately control chromium emissions discharged to the atmosphere from three of its chromium-electroplating tanks; 2) continuously maintain the pressure drop across the CMP systems equipped on these three tanks within the compliant range established during the respective performance test for each tank (by having the sum of the pressure drops across each individual stage of the CMP system exceeding the established range); and 3) continuously operate and maintain these tanks and equipped CMP systems in a manner consistent with good air pollution control practices.  EPA discovered these violations on an inspection it conducted of the facility on November 4, 2013, and through ChromeTech?s response to a February 26, 2014, information request.

To come into compliance, ChromeTech will provide EPA with documentation that it purchased and installed automated pressure
