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 HCN was sampled using CTM 033 with 6 Normal NaOH and an additional impinger for one hour per the clarification given by the USEPA in FAQ TEST-010. The preferred method is EPA CTM 033. The analysis is then with ion chromatography.
