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.

During the mercury and non-mercury metallic HAP testing, GEII did not meet the minimum requirement of 3.4 cubic 

meters of sample gas collected for the OTM-027 and OTM-028 testing. The sample volume collected for the three 

240-minute runs averaged 2.5 cubic meters (89 cubic feet), thus missing the stated requirement by 26 percent. Mr. 

Peter Westlin of the EPA’s measurement policy group agreed that the data from these runs satisfied the ICR 

requirements
