Where there are multiple effluent limits for the same <br />constituent, the lowest limit is indicated in the bold red font. Numeric action levels (NALs) are not effluent <br />limits, but levels at which the facility operators must take corrective action. <br />Bold blue font indicates WDR required sampling method <br />4.1.10 Additional WDR-required Monitoring <br />WDR-Required Storm Water Monitoring: <br />In addition to the above-described monitoring, the <br />County is required to also monitor storm water flows <br />semiannually for the semiannual field and monitoring <br />parameters specified in “Table F.3.c.” of Order No. <br />R5-2010-0016 (refer to the table to the right and <br />Appendix B of this SWMP). Every five years the <br />WDR-required constituents of concern (COC) must <br />be sampled and analyzed. The last sampling was <br />required in 2015, the next will be due by June 2020. <br />Sampling is required to be conducted at the following <br />locations (see table below and refer to SWPPP Map 2 <br />of this SWMP): <br /> <br /> <br />Table 4.1.C – WDR-Required <br />Constituents of Concern
