Gents

It appears we can use some help with this, in particular

- vetting the plant list to eliminate closed facilities and

- for operating facilities (listed, and others we may discover in the database), completing as much of the

“data needed” we have or can readily obtain.

We can discuss Friday (when Yi and I will be in) or Tuesday.

Thanks,

- Marc

Next steps?

Discuss after looking at the files?2 I originally plugged in the NAICS codes (while she was on the phone) and there are 50ish facilities listed. Some appear to

be closed (data is outdated) but I was unable to download the data (system seems to not be working). My plan was to

ask someone (Mark Wert or Bob Boisselle) to pul l an access report of the NAICS etc.

I did explain that we only implement the MACTs for those facilities subject to OP.

Karen,

Thank you for speaking with me today. As I explained in our 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 NESHA P 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 chr omium

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 th e 5 to 10 facilities in those States

that are likely to have the highest risk.

The facilities we are concerned with have the following classification codes:

NAICS: 332813

SCC: 3

‐ 09

‐ 010

‐ 018, 3

‐ 09

‐ 010

‐ 028, 3

‐ 09

‐ 010

‐ 038

Attached are two files, one containing th e facilities we have listed for MA, the other is a file that lists the specific types o f

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 operatio n (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 (pla nt 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,

and no later than the end of February 2 011.

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
