### 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.

-Method 26A - The laboratory analysis for HCl and HF was completed in accordance with Method 26A procedures and no analytical issues were encountered. During the time of sampling the normality of the NaOH impingers for HCN adsorption was not adjusted to maintain a pH above 12 through each test run. Although the test runs were conducted within method guidelines EPA issued guidance suggesting these modifications be made to maintain desired pH levels above 12. Furthermore, near the time of this test event or shortly after EPA posted to the ICRFAQS page that HCl/HF/HCN test runs using Method 26A procedures should be reduced to one hour from the threehour specification published in the original 114 letters. These tests were performed for three hours using the initial specifications.
-CTM-033 - HCN matrix spike was not performed.
-Method 5B/OTM28 - the probe/filter temp was not maintained at the temperature required by Reference Method 5B. When compared to the Method 29 particulate fraction data, we believe that the Method 5B/OTM-28 data is representative.
-Method 29 – A review of the inter-run variability for Manganese indicates that the third acceptable test run (Run 4) was significantly greater than the previous two acceptable test runs. There was no obvious reason for this difference and the elevated mass is associated with the back half analytical results.
-Method 29 – A review of the lab. QA report indicates that the data reported for Beryllium (Be) may be biased low.
-Method 30B – Each of four consecutive 45-minute runs was averaged to calculate three reported data periods. This was performed at the request of Southern Company Services to enable the co-completion of a Mercury CEMS RATA. Organic Condensible
