1.0 INTRODUCTION Stationary source sampling of the Anode Baking Furnace (A-446 Scrubber) located at the Century Aluminum Sebree, LLC (Century Aluminum) facility in Robards, Kentucky was performed by GEL Engineering, LLC (GEL) personnel on November 20-21, 2014.

This test program consisted of determining the emissions of fluoride (Fl) and polycyclic organic matter (POM) from the source. These tests were conducted to demonstrate compliance with Title 40 of the Code of Federal Regulations Part 63, Subpart LL (40 CFR 63, Subpart LL) and Kentucky Department for Environmental Protection (DEP) Division for Air Quality (DAQ) permit number V-12-015 (Revision 2).

2.0 TEST RESULTS Testing on the Anode Baking Furnace consisted of sampling at each of the three A-446 Scrubber stacks for one 240-minute run. There are a total of three stacks, one stack per scrubber reactor, which comprise the emission points of the Anode Baking Furnace dry scrubber/baghouse system. Testing was conducted using the following United States Environmental Protection Agency (EPA) methodologies.

The summary of test results, test method formulas and nomenclature, field data sheets, analytical data, plant process data, and equipment calibration records are enclosed in Appendices I through VI, respectively.

3.0 LOCATION OF SAMPLING Stationary source sampling was conducted on the Anode Baking Furnace A-446 Scrubber. As detailed previously, the A-446 Scrubber has three exhaust stacks. As per the approved Site-Specific Test Plan (SSTP), each stack associated with the bake oven was sampled for

240-minutes.

4.0 DETAILED PROCESS DESCRIPTION The Anode Baking Furnace is the oven process from the production of carbon anodes which are used on-site in the potlines. The carbon anodes are a mixture of carbon coke and tar pitch, which is formed into green anodes in the Green Mill. Thegreen anodes are placed in a ring furnace for a bake cycle, which consists of preheating, baking, and cooling. The furnace operates continuously with a production rate of approximately 400 anodes per day. After cooling, the baked anodes are supplied to the potlines for the use in the production process. The emissions from the baking furnace are ducted to a dry aluminum scrubber, also known as A-446 Scrubber, which cleans the gases emitted by the baking process. The scrubber employs a baghouse to control the particulate emissions.

5.0 IDENTIFICATION OF METHOD(S) USED Test parameters and sampling methods for the test program are summarized in Table 1. Sampling methods and analytical procedures recommended by the EPA were used during this test program. Laboratory and calibration procedures described in EPA Quality Assurance Handbook for Air Pollution Control Systems, Vol. III, (EPA/600/R-94/038c), and the QA/QC procedures specified in EPA Reference Methods 1, 2, 3, 4, 13B, and 315 were followed during execution of the test program. The sampling and analytical methodologies

are described below.Results of the November 2014 Emissions Testing of the

### 5.1 Stack Sampling Locations EPA Method 1 was used to determine the number and location of the sampling points for flow determination of the A-446 Scrubber. The approved SSTP detailed that each stack would be sampled for 240 minutes. The test points for the both sources are presented in Appendix II. Each stack is a 50.5-inch diameter stack and the sampling platform is located approximately 125 feet above the base of the stack. As specified by Method 1, a horizontal cross section of each stack was divided 24 equal areas with 12 traverse points located on one perpendicular diameter.

5.2 Velocity and Volumetric Flow Rates EPA Method 2 was used to determine the stack gas velocity and volumetric flow rates for the Main Stack. Velocity and volumetric flow rates were calculated based on the average of the measurements for each test run. The temperature of the stack was measured by a calibrated Type K Thermocouple positioned in the stack in

accordance with EPA Method 2.

5.3 Dry Molecular Weight In accordance with the guidelines in EPA Method 2, the dry molecular weight was assumed

to be that of ambient air or 29.0.

5.4 Moisture Content EPA Method 4 was used to determine the moisture content of the stack gas. Following the protocol given in Method 4, the volume of the condensed water vapor collected in the impingers and the silica gel were weighed before and after sample collection. The difference in the two weights of the silica gel, the difference in the two weights of condensed water vapor captured in the impingers, and the volume of air sampled with the impingers train were used to calculate the moisture content of the stack gas.

5.5 Emissions Determinations Sampling methods and analytical procedures recommended by the EPA were used during this test program. The sampling and analytical methodologies are described

below.

5.5.1 Fluoride Emissions Determinations One 240-minute test run was performed at each stack. The sampling train was equipped with a glass nozzle, a glass probe liner, a paper fiber filter, two impingers charged with deionized water, an empty knock-out impinger, and an impinger charged with silica gel. The Fl emissions were collected isokinetically through a heated sampling probe onto the heated filters. After completion of each sampling run, the sample train components including the nozzle, probe, and filter housing were rinsed and scrubbed until clean after each test run as per EPA Method 13B. The probe rinse/filter sample fractions, impinger
solutions collected from each run, and a field blank were then submitted to the ElementResults of the November 2014 Emissions Testing of the

### One laboratory and analyzed to determine particulate/gaseous Fl emissions.

5.5.2 Polycyclic Organic Matter One 4-hour test runs using EPA Method 315 to determine the POM emission rates were conducted on each stack. The sampling train was equipped with a Pyrex nozzle and probe liner, a high purity quartz filter, one Greenburg-Smith impinger and one standard impinger both charged with deionized water, one empty standard impinger, and one impinger charged with silica gel. POM emissions were collected isokinetically through the nozzle and probe onto the heated filter. The sample train components, including the nozzle, probe, and filter housing, were rinsed and scrubbed until clean after each test run as per EPA Method 315. The samples were marked, labeled, and shipped to Resolution Analytics for analysis.

### 13.1 Nozzles Each nozzle is purchased from a stack testing equipment supplier and inspected and calibrated before putting it into field use. Thereafter, it is inspected prior to use and if damaged, the nozzle is not used. A set of three measurements is made prior to use and must be within 0.002 inches. Nozzles are checked prior and after each source test.

13.2 Pitot Tubes All pitot tubes used by GEL are purchased along with the probe assembly from a stack testing equipment supplier. Prior to being used, the pitot tubes are calibrated as per Method 2. Pitot tubes are inspected before each source test and receive a complete calibration once per year.

13.3 Dry Gas Meter Complete dry gas meter calibrations are performed annually. After a source test, a single point calibration is conducted at the average orifice meter (DH) and maximum vacuum readings encountered during the test. If the dry gas meter calibration factor differs from the annual calibration by more than +/- 0.05, it is repaired and given another annual

calibration.

13.4 Thermocouples Each new thermocouple purchased by GEL is checked and calibrated prior to use. After each source test, all temperature-sensing devices used receive a one-point calibration check as per Method 2.

13.5 Balance

GEL technicians utilize an Ohaus Model E12140 Serial No. G2391121320091P balance. The serial number for the calibration weight set is 39325. A copy of the calibration log will be provided upon request.

13.6 Barometer GEL utilizes the National Weather Service to determine the current barometric pressure. This is obtained either by telephone or using the Internet.
