Dear Sir/Madam, The U.S. Environmental Protection Agency (EPA), is performing the residual risk and technology review of the National Emission Standards for Hazardous Air Pollutants: Hard and Decorative Chromium Electroplating and Chromium Anodizing Tanks (Chromium Electroplating NESHAP). Amendments to the NESHAP were proposed on October 21, 2010 (75 FR 65068), and EPA is under a court-ordered deadline to finalize the amendments by June 30, 2011. Several comments received on the October 2010 proposal stated that EPA lacked adequate data to fully assess the risk associated with emissions from chromium electroplating sources; other commenters stated that EPA did not account for the facilitieswith the highest risk. In response to those comments, EPA is now trying to collect data on potentially high risk facilities. The attached file lists the specific types of data needed, we would like to collect as many of the listed items as possible for each facility. The most critical data needs are:

For each chromium electroplating or anodizing tank:

· Type of chromium electroplating process (hard, decorative, trivalent, anodizing)

· Surface dimensions (length and width)

· Rectifier capacity (amperes)

· Limits on rectifier operation (ampere-hours per year)

· Maximum permitted process operating hours (hours per year)

· Typical process operating hours (hours per year)

· Emission control method

· Emission test data (complete test report, if available)

We would like to obtain the requested information as soon as possible, please fill-in the attached form and return it to me no later than the end of February 2011. If you should have any questions, please feel free to contact me at 717-772-3364. Sincerely, Tony A. Pitts
