Final Chrome Electroplating NESHAP Residual Risk Amendments Issued

On August 15, 2012, U.S. EPA issued final amendments to the NESHAP for Chromium Emissions from Hard and Decorative Chromium Electroplating and Anodizing Tanks, 40 CFR 63 Subpart N.   Every eight years, EPA is required to conduct a Risk and Technology Review (RTR) of each NESHAP to determine the residual risk and available control measures.  On October 21, 2010, EPA proposed an amendment to the Chromium Electroplating NESHAP (40 CFR 63, Subpart N) to reflect the RTR, and a supplemental RTR amendment was issued on February 8, 2012, which incorporated updated analyses and results.  EPA issued the final RTR amendments on August 15, 2012, but the rule has not yet been published in the Federal Register (expected soon).

Rule changes include:

  • A reduction in the chromium emissions limit for certain categories of affected sources.
  • An existing source compliance date for meeting the new emissions limits of no later than 2 years after the effective date of the final rule.
  • Additional housekeeping requirements to minimize fugitive emissions, which must be implemented no later than 6 months after the effective date of the final rule.
  • Minor revisions or additions to testing, monitoring, recordkeeping, and reporting requirements, including the introduction of the Electronic Reporting Tool (ERT).
