Attachments: DRAFT PAL_114 letter-survey and testing for RTR_04-05-11.doc

Charles/Mike,

Please distribute the attached draft version of an information collection request for the primary aluminum (PAL) industry to
the appropriate PAL personnel. A couple of notes on this document:

• The court

- ordered deadline for this RTR project results in a very tight schedule. This schedule may be further stressed if the Congress cannot agree on a budget and the government temporarily shuts down. With these
issues in mind, please review this document at your earliest convenienc e. I would like to set up a conference call to discuss this ICR with representatives of the PAL industry ASAP. Is there any way we could discuss this document Friday (04/08/11)? If not, can you suggest an alternate date (subject, of course, to the possibil ity of temporary government shutdown after this Friday)?

• The deadline for submittal of the requested information is very tight
- but the testing that we discussed earlier has been removed and only limited grab samples are now requested (as opposed to stack testing).

• I made an attempt at defining "normal facility production hours" and "normal operating year" in question 8 on page 7 of the document. In addition to any other comments you provide, please provide feedback on how to make

those definitions more ac curate/representative.

• The EPA attorney assigned to this project has submitted some comments to me which I have attempted to incorporate in the attached version of this document
- however, that attorney has expressed a desire to have a
meeting concerning t his project. That meeting could result in changes to the attached document.

Re: Requirement to provide information and conduct metal hazardous air pollutant analyses
according to Section 114 of the Clean Air Act

Dear Company contact :

We

, at t he U.S. Environmental Protection Agency (EPA) , are collecting information on

emissions of hazardous air pollutants (HAP) and other related information from p rimary

a luminum r eduction facilities , pursuant to our authority under Section 114 of the Clean Air Act

( CAA ) (42 U.S.C. 7414)

. The information gathered will be used by the EPA to perform a review

of the National Emission Standards for Hazardous Air Pollutants (NESHAP) f or Primary

Aluminum Reduction Plants in 40 CFR p art 63, s ubpart LL

, developed under s ect ion 112(d) of

the CAA ( 62 FR 52407 , October 7, 1997 )

. T he review of the NESHAP for primary aluminum
reduction plants is being conducted under sections 112(d) and 112(f) of the CAA

.

There are two components to this information request . The first component is a survey
requesting general facility information , information on production operations and emissions
controls, and reports of previously performed emissions testing for each of your primary
aluminum reduction facilities (Enclosure 1). The second compone nt is a requirement for testing
at your primary aluminum reduction facility and the procedures for reporting the associated test

data (Enclosure 2).

The authority for EPA's information gathering is included in section 114 of the CAA (42

U.S.C. 7414). All information submitted to the EPA as part of this request will be made
available to the public unless a satisfactory showing is made that public access to such
information would divulge methods or processes entitled to protection as confidential business

in formation or trade secrets. If you believe that disclosure of specific pieces of information you
submit would reveal confidential business information or a trade secret, you should clearly
identify such pieces of information. Please do not label an entire response “confidential” if only
certain portions consist of confidential business information or trade secrets. Refer to Enclosure
3 for the information that the EPA may require, at a later time, to support your confidentiality
claims. Any information det ermined to constitute a trade secret will be protected under 18 U.S.C.
1905, 5 U.S.C.A 552(b)(4), and EPA‟s implementing regulations at 40 C.F.R. Part 2, Subpart B.
If no claim of confidentially accompanies the information when it is received by the EPA, i t may be made available to the public by the EPA without further notice (40 CFR part 2.203,
September 1, 1976). Because section 114(c) of the Act exempts emission data from claims of
confidentiality, the emission data you provide may be made available to the public. For this
reason, questions on emissions data are listed in a separate section of the enclosed request for

information. A clarification of what the EPA considers to be emissions data is contained in

Enclosure 4. You should not mark the emission s data as confidential business information.Page 2 of 3 7

We have contracted EC/R, (Contract No. EP

- D

- 07019) and RTI International (RTI)

(Contract No. EP

- D

- 06118) to help us gather information about your industry. As noted in
Enclosure 5, we have designated EC/R (prim e contractor) and RTI (subcontractor) to be our
authorized representatives. Therefore, EC/R and RTI have the same rights EPA has as discussed

above and in Enclosure 3. This means that EC/R and RTI will have access to all information
provided to us in you r response to this request . As a designated representative of the Agency,
EC/R and RTI must, by law, also abide by the requirements of 42 U.S.C. 7414(c) in regard to the
confidentiality of what you claim to be trade secrets.

Enclosure 6 summarizes EPA‟s p olicies and procedures for handling confidential
information and describes EPA contractor commitments and procedures for use of confidential
materials. It is EPA‟s policy that compliance by an authorized representative with the
requirements detailed in En closure 6 provides sufficient information for the rights of submitters

of confidential information.

If you have questions regarding the need for this information request or need clarification
on the information requested, please contact David Putney with E PA‟s Office of Air Quality

P lanning and Standards

.

After you have completed the survey responses, you should remove any components you

wish to claim as confidential business information (CBI) from your survey and return the
completed non

- confidential surve y response and the test results and other requested information

by May 31 , 2011 at the appropriate address provided below

(including speciated hexavalent chromium)

1 .1 Sampling

- Bag House and Electrostatic Precipitator Particulate Matter

Sample and analyze the particulate matter collected in the hopper of each of the bag

houses or electrostatic precipitators used to control particulate matter from primary
aluminum potlines. In cases where solids from different compartments of a single bag

house or electrostatic precipitator are collected in multiple hoppers or multiple collection
sacks, a single composite sample will be adequate. Sampling should be conducted once per day for five consecutive operating days with a clean uncontaminated scoop or similar
apparatus, and all samples collected should be stored in a clean air

- tight conta iner.

Each sample should be approximately 50 grams, dry weight. Guidance on sample
collection can be found in of Chapter 4 of the document Superfund Program
Representative Sampling Guidance, Volume 1: Soil (EPA 540/R

- 95/141), which is
available through the following link:

http://www.epa.gov/tio/download/char/sf_rep_samp_guid_soil.pdf

. 2 Sampling

– Wet Scrubber Sludge , Injected Slurry (if applicable), and Discharge Water

Sample and analyze the scrubber sludge , injected slurry (if applicable) and any aqueous
blowdown stream discharged from the wet scrubber. Collect a representative grab sample
of approximately 50 grams dry weight of scrubber sludge. If a separate stream of
scrubber blowdown is discharged from the scrubber, collect a representative grab samplePage 27 of 3 7

of approximately 1000 milliliters of this stream. Sampling should be conducted once per day for five consecutive operating days.

1.3 Chemical Analysis

Analyze each sample of bag house or electrostatic precipitator particulate matter

, scrubber sludge , inje cted slurry (if any), and scrubber blowdown (if any) for individual

HAP metals as listed in Table 1 .1. Also analyze each sample for hexavalent chromium

. Methods for chemical analysis are given in Table 1 .2.

Method Detection Levels For Test Data Submitted in Response
to Information Collection Request (ICR) Progra ms

Identify the status of measured values relative to detection levels on the spreadsheet using the
following descriptions:

 BDL (below detection level)

– all analytical values used to calculate and report a fabric
filter particulate matter

, electrostatic precipitator particulate matter

, sludge, or scrubber

blowdown metal analysis are less than the laboratory ‟s reported detection level(s);

 DLL (detection level li mited)

– at least one

, but not all

, values used to calculate and

report a fabric filter particul ate matter

, electrostatic precipitator particulate matter

, sludge,

or scrubber blowdown metal analysis are less than the laboratory‟s reported detection

level(s); or

 ADL (above detection level)

– all analytical values used to calculate and report a fabric
filter particulate matter

, electrostatic precipitator particulate matter

, sludge, or scrubber

blowdown metal analysis are greater than the laboratory‟s reported detection level(s).

For each reported emissions value, insert the appropriate flag (i.e. BDL, DLL , or ADL) in

the Note line of Excel emission t est spreadsheet template.

When reporting and calculating individual test run data:

 For analytical data reported from the lab as “nondetect” or “below detection level;”

 Include a brief description of the proc edures used to determine the analytical

detection levels in the Note line of Excel ® emission t est spreadsheet template.

 Describe these procedures completely in a separate attachment including the
measurements made, the standards used, and the statistical procedures applied.

 Report the calculated emissions concentration or rate result as a bracketed “less

than” detection lev el value (e.g., [<0.0105]) in the Excel ® emission t est spreadsheet template

 Report as numerical values (i.e., no brackets or < symbol) any analytical data
measured above the detection level including any data between the analytical

detection level and a la boratory

- specific reporting or quantification level (i.e., flag

as ADL).
