Page 32 of 20 PART C: START

- UPS AND SHUTDOWNS

Please provide the information in Table 6 and questions below for each Subpart LL p otline

during start

- up (the commencement of operation for any purpose) and shutdown (the cessation of

opera tion for any purpose) operatio ns. For the purposes of Part C of Enclosure 1 start

- up and

shutdown refers to the commencement and cessation of operations of a potline, not of an

individual pot (e.g. after anode changes).

1 6

. Please provide a rationale, if a pplicable, for why application of the Subpart LL standards to

a potline during start

- up or shutdown is not practica b l e economically or technologically

Not practicable economically: ___ EPA Reference Method 14 is designed to measure TF

roof emissions over a representative section of operating reduction cells (about 10 out of

174 or 160 in the potline). These cells are believed to be representative of all of the entire

potline during normal operations. During startup, cells located under the Method 14

manifo ld do not represent the entire potline because the cells are in various stages of

startup or non

- steady

- state operation. It would not be technically practicable to establish a

startup standard, or to show compliance with a standard using Method 14. Start ups are rare

and conditions of the startup vary depending on whether the potline was shut down by an

emergency (e.g loss of power) or intentionally shut down with time to prepare and plan.

Work practice standards are the only practicable way to regulate e missions during potline

startups.

__________________________________________________________________ Not practicable technologically: ___ Collecting Method 14 samples representative of the

whole potline during startup is not practicable economically because it would require the

installation of multiple sampling manifolds in each potline to be able to collective

representative samples. The cost of installing these sampling manifold systems would be

excessive because they would only be used on extremely rare o ccasions. We have only had

to restart potlines one time since 1986 and that was only because of an ice storm knocking

out power to the plant.

(including speciated hexavalent chromium)

1 .1 Sampling

- Bag House and Electrostatic Precipitator (ESP) Particulate Matter

Sample and analyze representative particulate matter (e.g. in the hoppers) collected by

each of the bag houses or ESP used to control particulate matter emissions from primary

aluminum potlines

. In cases where solids from different compartments of a single bag

house or ESP are collected in multiple hoppers or mul tiple collection sacks, a single

composite sample will be adequate. Also, if multiple potlines of the same type (e.g. HSS,

SWPB, CWPB1, etc.) are supplied with alumina from the same alumina storage vessel,

sampling of representative particulate matter fro m the bag house or ESP associated with

one of those potlines will be adequate

. Sampling should be conducted once per day for

five consecutive operating days with a clean uncontaminated scoop or similar apparatus

. A ll samples collected should be the approxi mately the same weight and stored in a clean

air

- tight container.

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 t he following link:

. 2 Sampling

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

Sample and analyze a representative grab sample of the scrubber sludge , injected slurry (if applicable)

, and any aqueous blowdown stream discharged from the wet scrubber. If a

separate stream of scrubber blowdown is discharged from the scrubber, collect a

representative grab sample of this stream. Also, if multiple potlines of the same typ e (e.g.

HSS, SWPB, CWPB1, etc.) are supplied with alumina from the same alumina storage

vessel, sampling of representative scrubber sludge, injected slurry (if applicable), and any

aqueous blowdown stream from the wet scrubber associated with one of those potlines

will be adequate

. Sampling should be conducted once per day for five consecutiveEnclosure 2

Page 1 of 1 Guidance For Calculating And Reporting Measurements Less Than

Method Detection Levels For Test Data Submitted in Response

to Information Collection Request (ICR) Programs

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 prec ipitator 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 particulate 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

filt er 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 the Microsoft® 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 procedures used to determine the analytical

detection levels in the Note line of the Microsoft® Excel emission t est

spreadsheet template.

− Describe these procedures completely in a separate attachment including the

measurements made, the standards us ed, and the statistical procedures applied.

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

than” detection level value (e.g., [<0.0105]) in the Microsoft® Excel emission t est

spreadsheet template

− Report as numerical value s (i.e., no brackets or < symbol) any analytical data

measured above the detection level including any data between the analytical

detection level and a laboratory

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

as ADL).
