# TOPICS DISCUSSED AND ACTION TAKEN

On December 6, 201 3 at 11:02 am I called Kelly Morgan (303

- 692

- 3634) and left a message asking her to return

my call

.

On December 11, 2013 at 10:43 am I called Erin Scott (303

- 692

- 3506) and left a message asking h er to return

my call.

On December 16, 2013 at 3:37 pm I spoke with Leslie Simpson (303

- 692

- 3517). She asked that I send an e

mail with my request.

On December 18, 2013 at 3:31pm I attempted to call the contacts listed in the facility fact sheet. As thes e

numbers were disconnected, I called Frank Dale (303

- 692

- 3526) at the Colorado DPHE and left a message

requesting that he forward me more recent contact information.

On December 19, 2013 at 10:06am I called John Cochran (928

- 913

- 9218), whose contact info rmation had been

forwarded to me by Frank Dale. John works for the parent company of Seneca Mine. He stated that 2011 had

been an especially long and heavy year of snowfall, with the amount of precipitation equaling that of the 200

year event. As a resu lt, their discharges were much higher than normal in the first two quarters of the year . In

addition, the boundary of area feeding some of the outfalls had been re

- drawn to include additional discharge

. He also corrected a reporting error for outfalls 00 5, 006, 010, 011, 016 and 017, stating that the values are listed

to be mg/L but were reported in ug/L (each value should be divided by 1,000).

On January 2, 2014 at 10:22am I called John Cochran again to confirm that the data changes were correct and to

discuss another potential outlier that may need correction. He did not answer, so I left a message.

On January 7, 2014 at 10:27am John Cochran returned my call. He offered to send me copies of the original

DMR reports but wanted more information about our contract with EPA and what information is required. I

agreed to send him an e

- mail with this information.

Please see attached email correspondence for additional information on the facility.

Re: 2011 NPDES Permit Request

Hi Julia,

We have not issued a permit for this facility in 2011. The third amendment issued 5/26/2010 is still in effect

under an administrative exten sion. I have attached both that amended permit and the fact sheet.

Please let me know if there is anything else.

Thanks,

Frank

- mailing you on EPA's behalf to request a copy of the 2011 NPDES Permit for the

Seneca Coal Mine in Hayden, CO (CO0000221). Here is some background on what the information is used for.

EPA reviews publicly

- available DMR data to fulfill its review obligation under Section 304(b) of t he Clean Water Act (CWA).

The CWA requires EPA to annually review and, if appropriate, revise its water pollution control technology

- based

regulations, called "effluent limitations guidelines" or "effluent guidelines," that limit the discharge of pollutant s to waters

of the U.S. from various categories of industrial facilities. EPA is currently conducting its 2013 annual review of existing

effluent guidelines 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 2013 Effluent

Guidelines Program Plan scheduled for publication in the Federal Register in 2014. As part of the 2013 a nnual review, EPA

is evaluating the data in discharge monitoring reports from 2011 and needs further information to complete the review.

Please call me at (703) 633

## Julia:

I talked with Bill Swietlik today, and he confirmed what I was thinking you folks were asking for and why.

Accordingly, I have attached two Excel files that provide the data I believe you will need to complete your assessment of

Seneca’s iron da ta reported for 2011. The file names should be intuitive, as one provides all total recoverable iron lab

results, and the other provides flow rates collected at the time the samples were collected. The total recoverable iron

data are provided in mg/L, an d the flow rates are in gallons per minute.

Please don’t hesitate to contact me if you have any questions going forward.

### As part of the 2013 annual review, EPA is evaluating 2011 DMR data and needs further information to complete the

review. Specifically, we would like to confirm the amount of iron discharged in 2011 from Seneca Mine. Please send a copy

of the 2011 DMRs for outfalls 005, 006, 0 08, 010, 011, 012, 013, 016 and 017.
