### 2. SOURCE DESCRIPTIO N AND PROCESS OPERAT ING DATA
This section provides descriptions of the process and emissions control equipment, as well as process operating conditions during the compliance testing.



### 2.1 PROCESS DESCRIPT ION The ALCOA Massena Operations East Plant primary aluminum reduction operation is located on the St. Lawrence Plant just east of Massena, NY. This opera tion is comprised of three horizontal stud soderberg (HSS) potlines. The potline operation manufactures metallic aluminum by the electrolytic reduction of alumina (Al2O3) in HSS reduction cells (or pots). Direct electrical current passing through a molten cryolite bath (the electrolyte) between a large carbon anode and the cathode electrolytically reduces the alumina added to the bath to aluminum and oxygen. The oxygen produced oxidizes and consumes the carbon anode. Molten aluminum is deposited and

accumu lates over time on the cathode beneath the layer bath. Periodically the molten aluminum is siphoned from beneath the bath and cast into foundry pig.
Massena Operations East Plant is comprised of 504 HSS pots with 168 pots in each of the three potlines. E ach potline has two rooms with 84 pots each. Emissions from the potlines are captured by the hooding around each pot which are controlled through the primary emissions control system. The potline primary emissions control system is comprised of three dry scrubber devices and two wet scrubbers. The emissions not captured by the hooding are emitted through the roof vents in each room. 

### 2.2 PROCESS OPERATING CO NDITIONS DURING TESTING Testing of each potline was conducted during a single operating condition th at represented typical process operating conditions. During each test run facility personnel monitored and recorded the following process data:

» aluminum production (lb)

» potroom flow rates (dscf/min) A summary of the aluminum product ion and potroom flow rate information are included in Appendix A

.

### 3. 3 GAS ANALYSIS AND DRY MOLECULAR WEIGHT The molecular weight of the stack gas was measured using a Fyrite ® 

### apparatus in accor dance with USEPA RM 3 . These data
, along with the moisture content and velocity data, were used to relate pollutant concentrations to mass emission rates (lb/hr). 

### 3. 4 MOISTURE CONTENT Moisture content during each test run was quanti fied utilizing procedures identified in US EPA RM 4 in conjunction with each isokinetic test run. A sample of gas was continuously collected using a dry gas meter stack sampling system and condensed in a series of impingers. The moisture content of the gas was measured as a change in the volume of the water collected in each impinger and the increased weight of the dessicant during each test run.

### 4. RESULTS, DISCUSS IONS AND CONCLUSIONS
The results of the test program are presented in Table s 1 through 10 . The following section briefly discusses the results. Field data sheets and emission calculations are presented in Appendix C. Laboratory data is presented in Appendix D.



### 4.1 PCCD/DF EMISSION TEST RESULTS (TABLES 1 AND 6)

Table s 1 and 6 contain the results of the PCDD/DF testing on the FTC scrubbers and the Line 3 Potline, respectively. A review of Table 1 indicates that the total PCDD/DF emissions normalized to aluminum production rate averaged < 1.34E

- 09 lb/ton of aluminum (lb/ton Al) for both scrubbers combined (TEQ Equivalent). Note that this aver age result was obtained by averaging the first two test runs that were conducted on the South FTC scrubber and adding it to the third test run which was conducted on the North FTC scrubber.
