Lucy,

Attached is an Excel® spread sheet of the Cr source in Illinois that I know of.

The details you are looking for would most likely be contained in the permit application and or

permit, which I don’t have access to.

Your best bet would be to submit a FOIA request in for the facilities which you would like more

information on.

Subject: Chromium Electroplating test data request

Dear Mr. Mattison;

Thank you for returning my call this afternoon.

The EPA is under a court-ordered deadline to finalize the amendments by June 30, 2011. Several

of 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; othercommenters stated that EPA did not account for the facilities with the highest risk.

In response to those comments, EPA is now trying to collect data on potentially high risk facilities.

These would be larger facilities or those that are near sensitive receptors. RTI International is

assisting EPA in this effort by contacting several State agencies to request data on the 5 to 10

facilities in those States that are likely to have the highest risk.

Attached is a file that lists the specific types of data needed, and 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)

In order to remodel risk for this source category and re-evaluate the regulatory options for

reducing risk to acceptable levels, while meeting the June 30, 2011 deadline, we would like to

obtain the requested information as soon as possible, and no later than the end of February 2011.

If you have any questions about this request or would like to discuss any issues related to the

Chromium Electroplating NESHAP, you can contact Phil Mulrine with EPA's Office of Air Quality

Planning and Standards. Phil can be reached by phone at: 919-541-5289, or by email at:

mulrine.phil@epa.gov

.

Thanks again for your help, and I look forward to talking to you soon.
