All effluent must be contained until analyses have confirmed that all numeric <br />effluent limitations have been met. If the results of the initial sampling exceed any numeric <br />effluent limitation, additional treatment shall be completed and additional sampling must be <br />collected, post- treatment, to confirm compliance with the limitations. Additional sampling and <br />treatment shall be repeated, and all water shall be collected and retained, until monitoring results <br />for the treated effluent verify compliance with the numeric effluent limitations identified in the <br />permit. This requirement will not be imposed for TDS where report only is required. <br />b. In order to be able to sample and determine compliance with the limitations at Outfalls OO1B, <br />002B and 002C, the permittee shall take the appropriate steps to create collection and holding <br />ponds, with treatment as needed, or route the water to the treatment ponds for Outfalls 001 A and <br />002A. <br />c. Rainfall /Storm Monitoring - The permittee must document the following information for Outfalls <br />001B, 002B and 002C for any rainfall /storm event, in the cover letter with the DMRs: <br />i. The date of precipitation event, time of sampling, duration (in hours) of individual rainfall <br />event, and magnitude (in inches) of each rainfall or storm event; <br />d. Snowmelt Monitoring - For snowmelt monitoring, the permittee must identify the date of the <br />sampling event. <br />
