Ms Hancy,

I regret not responding sooner to your request, but have been awaiting guidance from my management.

Anyway, I have been authorized to provide the attached list that reflects company names and permit

numbers for a number of facilities that conduct chrome plating and/or anodizing.

Now this list does not include all the chrome plating operations in Texas, but this will provide you a

starting list.

I have a longer list that I'm reviewing to weed out those that are no longer in business or have ceased

chrome plating operations.

Using the attached list, you will be able to access the permits for the listed companies on the TCEQ WEB

site. The permits will not include all the data you have requested, but will include allowable emission

rates, rectifier capacities, type controls used, and a variety of other information.

Some of the data you identified will be in the permit applications submitted and these files are available

through our central records office, telephone number 512-239-2900.

Now some of the details you need will only be available from the permit holder.

I hope the attached list is helpful and if you have question, please give me a c all.

As I identify additional permit holders, I'll provide you the revised listings.

Respectfully,

Dois Webb

Permit Engineer

Dois,

I wanted to follow up with you on the information requested for Cr. Electroplating facilities. I have

attached a more detailed document regarding the information EPA is seeking. Please feel free to

contact me if you have any questions.

Thanks again for your help,

Subject: Electroplating Information Request - EPA

Dois,

Thank you for speaking with me today. As I explained during our telephone conversation, 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 facilities with the highest risk. In response to those comments, EPA is now trying to collect

data on potentially high risk facilities. 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.Cindy Wang Hancy
