Description of the source (including control equipment). Please see the attachments for source or

 process flow diagram:

Widows Creek Unit 7, located in Stevenson, AL is a coal fired utility boiler with a design rating of 500 MW. It is a 

tangentially fired Combustion Engineering dry bottom boiler burning high sulfur bituminous coal. The unit is 

equipped with low NOx burners and a selective catalyst reduction (SCR) system for NOx emissions control, an 

electrostatic precipitator and SBS injection for control of particulate emissions and a wet scrubber for control of SO2 

emissions.

The following describes any modifications and/or deviations to the applicable test 

methods. If alternative methods were requested, see the attachments for documentation 

of request AND approval, including dates.

The required coal sampling will be performed in accordance with ASTM D2234-00 utilizing manual sampling 

practices found in ASTM D6609-08 “Standard Guide for Part-Stream Sampling of Coal”. The sampling device will 

comply with ASTM D 6883-04 section 7.6. The coal samples will be manually collected from one or more coal scale 

(s) or coal feeder(s) located between the coal bunker and coal pulverizer. A minimum of 35 primary increments will 

be collected per sample. These increments will be systematically spaced so that they are collected over the entire test 

period. While collecting samples at these locations is not specifically addressed by the ICR, it ensures that the coal 

being burned during testing and the coal being sampled are the same. One gross sample will be collected to represent 

the entire test period. All pollutants measured during the test period will be represented by the same gross sample. It 

is expected that the gross sample will weigh between 210 and 350 pounds of 2 X 0 size coal. The gross sample will 

be manually divided to approximately 40 pounds utilizing either “the cone and quarter technique” or the “alternate 

shovel method”. While not specifically identified, the “cone and quarter technique” is inferred in section 2.2 of the 

ICR ”Create a Composite Sample for Solid Fuels” steps 3-4 of Part III: EMMISSIONS TESTING. This technique is 

also illustrated in figure 4 of EPA 600//X-90/043 from February 1990. The “alternate shovel method” of manual
