For #1: everything matched my records except Cadmium, I hav e 0.0000226 mg/L.

For #2:

All the Flows have been corrected

- 1.792 x 10-1 MGD for March 2008

- 3.2582 x 10-2 MGD for June 2008 - 4.5616 x 10-2 MGD for Sept 2008 Also we have gone back five years and corrected all flow data. We were not converting the data, this has been corrected.

Dear Ms. Williams,

Thank you for your time on the phone today. Easter n Research Group, Inc. (ERG) under EPA Contract No. 68-C-02-095 is e-mailing you on EPA's behalf to request information on 2008 discharge monitoring reports for the Advantage Meta ls Recycling facility (MO0115801). Here is some background on what the in formation is used for.

EPA reviews publicly-available DMR data to fulfill its review obligation under Section 304(b) of the C lean Water Act. The CWA requires EPA to annually review and, if appropriate , revise its water pollution control technology-bas ed regulations, called "effluent limitations guidelines" or "effluent guidelines," t hat limit the discharge of pollutants to waters of the U.S. from various categories of industrial facilities. EPA is currently conducting its 2010 annual review of existing effluent guidel ines and potential industrial guidelines which may need to be included (see http: //www.epa.gov/guide/304m/ for further information). EPA will discuss this

review and the results in its 2010 Effluent Guideli nes Program Plan scheduled for publication in the F ederal Register in December 2010. As part of the 2010 annual review, EPA is eva luating the data in discharge monitoring reports fr om 2008 and needs further information to complete the review.

We would like to obtain additional information on t he following data from Advantage's DMRs.

1. What were the units and concentrations for: - Copper in Sept 2008 (our data show 0.729 mg/L) - Mercury in Sept 2008 (our data show 0.00291 mg/L) - Iron in March, June, and Sept 2008 (our data show 49.9 mg/L, 0.218 mg/L, and 33.6 mg/L, respectively ) - Cadmium in Sept 2008 (our data show 0.0040000226 mg/L) - Silver in Sept 2008 (our data show 0.0056 mg/L)

2. What are the units for flow? Our DMR data show:

- 1.792 MGD for March 2008

- 3.2582 MGD for June 2008 - 4.5616 MGD for Sept 2008

We appreciate your help in confirming if the above data are accurate, or if there are units errors in the DMR data, as we expect.

If you have any questions regarding this request, p lease call me at (703) 633-1673. If you would like to speak directly with EPA regarding this request, you can contact William F. Swietlik of EPA's Office of Water/Engineering Analy sis Division by phone at (202) 566-1129 or by email: swietlik.william@epa.gov<mail to:swietlik.william@epa.gov>.

Thanks,

Ellie Codding
