-Method 26A /CTM-033 - 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 

ICR FAQS page that HCl/HF/HCN test runs using Method 26A procedures should be reduced to one hour from the 

three-hour specification published in the original 114 letters. These tests were performed for three hours using the 

initial specifications. 

-The CO2 gases near 13% within each source gas stream exhaust the adsorption potential of the NaOH solution and 

therefore some measurable levels of HCN may be passed through the solutions when present. HCN results seen at 

subsequent units at other Southern Company plants firing similar coal showed conclusively that HCN levels were 

DL. As a result, these test were qualified for HCl and HF and were not reported for HCN.

-CTM-033 - Reference method requires a matrix spike, but this was not performed.

- Please also note that the values presented in this database and the values in the hard copy report will vary slightly. 

We expect these differences are due to the fact that the ERT database recalculates all values.
