Weekly Grab <br />Salinity f;' g/ Quarterly Grab <br />' ~ Self-monitoring samples taken in compliance ~~~~i[h the monitoring requirements <br />specified above shall be taken at: The discharge points are as follows: <br />001- the overflow from pond .JI located i~~ the Southwest 1/4 of [he Southeast <br />1/4 of Section 9. <br />' 002- the overflow from pond '2 located in the Southeast 1/4 of the Southwest <br />I/4 of Section 9. <br />' 003- the overflow from pond ,d3 located in the Southeast 1/4 of [he Southwest <br />I/4 of Section 9.

The permittee shall indicate on the monitoring report <br />when the discharge is caused by this snowmelt or rainFall event. <br />e/ See definitions, Part B. <br />`/ Salinity shall be measured as Total Dissolved Solids (TDS) or electrical con- <br />, ductivity where a satisfactory correlation with TDS has been established <br />based on a minimum of five (5) samples. Samples shall be taken at [he per- <br />mitted discharge point. <br />' a/ Salinity shall be sampled on a monthly hasis until six samples have been <br />analyzed. Thereafter, monitoring shall continue on a quarterly bas s. <br />Following submittal of [he first six months of data, the Division shall de- <br />r_ermine eligibility of a waver of numer.c limitations based on sal[-loading, <br />If a waiver is no[ granted: then Che permittee has an additional six months <br />to submit a report addressing smolt removal in accordance with Regulations <br />" "' 3.10.0 - 3.10.5 and Appendix A. <br />REVISED May 15, 1°81 <br />
