Ok - I have organized it by NYS regions which will have no meaning for your work but helps me to keep

track of which office I am receiving the information from. I tried to leave text in 'red' for the areas where

I expect more information.

You will be receiving 5 Excel files (Region 1, 3, 4, 6, 9). Second email to follow with the remainder.

Randi;

Wonderful! Why not send what you have now. It will give a chance to look it over.

Thanks,

Lucy

Hi Lucy,

I have compiled information on 9 of 11 chromium electroplating facilities in New York State. I am still

waiting to obtain information on two facilities. I am also waiting to hear back on two specific questions

on facilities for which I have complete information.

Do you want me to send what I have now or wait a day or two for the complete set? We are having a

bit of snow today and that may be the reason I have not received all information from our regional

offices.

Thanks,

Randi

Randi;

Thank you for your help.

The annual revenue is not high priority. As far as the facility data goes, name and location are what

we are really need.

On the list that we sent, the next four categories: process type, tank design and operation, emission

control technology, and emission test data would be very helpful.

We will gladly take all of the facility data that you can provide, but just getting the 5-10 highest risk

facilities (largest or near sensitive receptors) will be fine.Please let me know if you have any other questions.

Thanks again,

Lucy Adams

Subject: Fwd: Chromium Electroplating information request

Hi Lucy -

I am working with Steve DeSantis on fulfilling your request for more information from facilities.

Regarding the annual revenue - are you asking about revenue for the entire company or just the portion

that relates to chromium electroplating? For some of our facilities, their work involves more than just

chromium electroplating.

Thank you.

Randi

Dear Mr. Desantis;

We spoke on the telephone last month about U.S. EPA’s efforts to collect data on chromium

electroplating facilities.

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; 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.

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.
