III. SUMMARY OF DISCUSSION

EPA Comments on Test Plan

The discussion began with Eramet's responses to questions raised by EPA regarding the test

protocol provided by Eramet for the testing to be performed the week of March 4, 1013:

Comment: Manganese must be included in list of analytes for Method 29. The test plan that

Eramet submitted today lists Mg (magnesium) on page 2

- 3. We expect that this may be a typo

(i.e., should be Mn). Nevertheless, the list of metals must include manganese (Mn), and

magnesium (Mg) is not required.

Response: Yes, this was an error. Testing for Manganese will be performed.

Comment: The tester should conduct field blanks wit h Method 29 or 26A sampling and CARB

428 and 429. Refer to the CARB 429 analytical particulars listed in our ICR request. In section

4 of the test plan there is no mention made of field blank trains being collected for analysis with

CARB 428 and 429, but we believe that is a requirement of the method, as are field spike

samples. Field spikes for the other tests are also desirable.

Response: Yes, field blanks will be conducted, including spiking the traps for Method 428

- 429

trains.

Comment: For the tapp ing baghouse, Hg testing using method 30B must be included, as shown

in the plan received today. However, regarding the spike level (3800 nanograms), we believe

this would be inappropriate. We suggest a spike level closer to 100 ng for that test, but the tester

should really do what they judge is best, to support the data, in the field. 3,800 nanograms seems

like a fairly high spike value for the method 30B (Hg) testing, but determining the correct spike

value is really up to the tester. We believe that this value should be determined based on the

criteria in the test method and prior measured values at the source.

Response: Although the method does recommend a spike of 50

- 150% of expected source

concentration, testing of the tapping operation has not b een previously performed and thus the

proper level for the spike is unknown. In the absence of further data, they have assumed it is

similar to the main furnace.

Comment: There should also be discussion of employing Chain of Custody documentation to

accom pany all lab samples from the field.

Response: Yes, chain of custody will be documented. A courier will be employed to hand

deliver all samples to the labs.3

Testing Schedule

Next, EPA asked for a brief summary of the expected schedule for the testing. Eramet replied

that the equipment was currently being unloaded, and testing was expected to begin later in the

day, and to generally follow the plan laid out in the test plan.

Day 1, Monday 3/4/13: Load in, Begin PM, Metals, Hg

Day 2, Tuesday 3/5/13: Finish PM, Metals, Hg, Start HCl & PCB/Dioxin/Furan

Day 3, Wednesday 3/6/13 Finish HCl, Finish PCB/Dioxin/Furan if possible

Day 4, Thursday 3/7/13 Complete any remaining tests, Load out.

Presence of OH EPA Representative

EPA asked if Ohio EPA wou ld be present for the testing, and if there was a person they could

contact to discuss it. Eramet stated that Ohio EPA would be present for the compliance testing

portion, on Tuesday the 5th. The representative will perform periodic monitoring of the

pro cesses and controls, post

- test leak checks, recovery, QA/QC, and observe visible emissions.

EPA requested a conference call be arranged to discuss the possibility of the OH EPA

representative staying an extra day to witness the PAH testing. The Eramet re presentatives

provided a contact for EPA to call for discussion: Dean Ponchak, Air Testing Group Leader, OH

EPA (740) 380

- 5297.

Visible Emissions Observation

EPA asked if visible emission testing will be performed. Eramet stated that standard opacity

te sting is a part of the compliance testing being performed on Tuesday. EPA requested that VE

tests be performed during the other testing as well, if possible. Eramet agreed that it would not

be difficult to comply with EPA's request, although they would no t be performing the VE testing

on the same schedule as for the compliance tests, since the events being monitored don't always

last the full hour required for compliance testing.
