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 division is described in ASTM D 346-04, section 10.3. TVA will not perform manual crushing of the material during
