Cr Electroplating Data Needed TO STATE.doc

Hi Cindy - This was routed to me for a reply. Looks like you've got a fair amount of work to do

. Were

you planning to send someone to go through our files ?

Barring that, you should search online

at http://dnr.wi.gov/cias/am/amexternal/AM_PermitTrackingSearch.aspx to gain the information for the

permit and emission information for the companies on the list. Several of these appear to be out of

business. Others, like Scot Industries, has an extensive collection of permits that contain the

information you are looking for. If you find a source that you need more information about, you may be

able to contact me, or the inspector, to put a compliance document on line through the same search

site. How would you like to proceed?

Brian,

As I explained in my voicemail, 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 are two files, one containing the facilities we have listed for Wisconsin, the other is a file

that 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)

· Any updates to Cr. Electroplating facilities listed in the attachment (plant closings, etc.)

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.

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.
