EXECUTIVE SUMMARY 

Custom Stack Analysis, LLC. conducted emissions sampling using USEPA Methods 1-4 and 26A. Testing was conducted for velocity, temperature, moisture and hydrofluoric acid emissions on the Kiln #3 outlet on September 27th,2007. The testing was conducted for compliance purposes. The Custom Stack Analysis, LLC. test crew consisted of Mr. Joe Crowe, Mr. Jeremy Persillo and Mr Brad Bailey. The testing procedures were coordinated by Mr. Ed Milliken of Bowerston Shale Company. All testing procedures were witnessed by Mr. Steve Alspach of the Ohio EPA Southeast District Office. 

A description of the testing protocol is included on pages 3-4. All testing calculations are located on pages 7-9. Appendix 1 includes field test data. Appendix 2 contains laboratory data from Custom Stack Analysis, LLC and Data Analysis Technologies, Inc. Appendix 3 contains calibration data for equipment used on test day. Appendix 4 contains production data Bowerston Shale Company. Test results are located on page 2.

METHOD 

Sample and velocity traverses for stationary sources. 

To aid in the representative measurement of pollutant emissions and/or total volumetric 

flow rate from a stationary source, a measurement site Where the effluent stream is flowing in a 

known direction is selected, and the cross-section of the stack is divided into a number of 

equal areas. A traverse point is then located within each of these equal areas. 

METHOD 2 

Determination of stack gas velocity and volumetric flow rate. 

The average gas velocity in a stack is determined from the gas density and from 

measurement of the average velocity head with a Type S (Stausscheibe or reverse type) pitot tube. 

METHOD 3 

Gas analysis for the determination of dry molecular weight. 

This method is applicable for determining carbon dioxide and oxygen concentrations 

and dry molecular weight of a sample from a gas stream of a fossil-fuel combustion process. 

METHOD 4 

Determination of moisture content in stack gases. 

A gas sample is extracted at a constant rate from the source. It is determined either 

volumetrically or gravimetrically.

METHOD 26A TESTING DESCRIPTION 

Samples were collected following EPA Method 26A. Three 60 minute tests were 

performed. The equipment used for testing consisted of a Burrell Model B orsat analyzer and a 

Custom Stack Analysis Sampling Apparatus (EPA type). A type "S" pitot and.a heated 

sampling probe was used with the sampling train. All equipment was calibrated in the 

laboratory prior to the test. The sampling nozzle and the pitot tubes were measured on the day of the test. All calibrations can be found in the appendix. The gases are passed through a 

heated pyrex probe and a heated glass four inch filter holder containing Pallfiex TX40H145 

filter media. The gases leaving the filter were collected in a series of six impingers packed in 

ice. The first, second and third impinger shall be of the Greensburg-Smith design with a 

standard tip. The first two impingers contained 100 ml of 0.1 N H2SO4. The next impinger contained 100 ml of 0.1 N NaoH and the last impinger was left empty. After passing through the fourth impinger the gases pass through a "Drierite" column containing about 500 grams of 

calcium sulfate (CaSO4) desicant to remove the remaining water vapor. The dry gas then 

passed through the hose portion of the umbilical cord to a Custom Stack Analysis Model 

#3000 stack sampling module. In the module the gas was moved through the system by a 

leakless air pump to a Rockwell 175-S dry test meter. The dry test meter exhausted to a 

calibrated orifice to measure the flow rate of the gases passing throuqh the sampling apparatus. A type "S" pitot tube was attached to the sheath of the heated p•robe and nozzle. 

The orifice pressure taps and the pitot tube were connected to a Dwyer dual 10 inch 

combination inclined-well type manometer. One half of the manometer measured the orifice 

differential pressure (^H) and the other half measured the flue gas velocity head (^P). The 

temperature of the flue gas was measured by a type "K" thermocouple connected to a Marlin 

Digital Temperature Indicator. The C02 and 02 levels were determined using a Burrell 

"Industrial Model B orsat analyzer. 

Sample recovery was performed according to USEPA Method 26A section 6.2.
