On April 26, 2001, your facility made a request that a clarification be made to the effluent limits page regarding the permit limit for cyanide. A cyanide footnote has been added to the effluent limits page stating that a value of less than 10 µg/L will be considered zero for compliance purposes. Additionally, you should consider adherence to the quantitation level of 10 µg/L for cyanide as fulfilling the intent of Part II Section D. (4) of the NPDES permit for utilization of the most sensitive laboratory methods possible. Please find enclosed the revised permit pages. The revised pages should be inserted into your permit.

We are uncertain, however if we are required under the regulations to analyze these additional samples even when they are not needed. We would appreciate any information you might have on this issue. Also, the Effluent Limitations and Monitoring Requirements page in our permit still has the word "DRAFT" printed on it. Since this is the final permit, we request that a new replacement page without this designation be issued. Thank you for your attention to these items.
