Monitoring and Sampling Requirements (4.0) <br />Monitoring includes visual inspection, sampling for water quality parameters of concern, and <br />documentation of the inspection and sampling findings in a site log book. A site log book will be <br />maintained for all on -site construction activities and will include: <br />• A record of the implementation of the SWPPP and other permit requirements <br />• Site inspections <br />• Stormwater sampling data <br />Create your own Site Inspection Form or use the Construction Stormwater Site Inspection Form <br />found on Ecology's website. https://www.ecology.wa.gov/Regulations-Permits/Permits- <br />certifications/Stormwater-general-permits/Construction-Stormwater-permit <br />File a blank form under Appendix D. <br />The site log book must be maintained on -site within reasonable access to the site and be made <br />available upon request to Ecology or the local jurisdiction. <br />Numeric effluent limits may be required for certain discharges to 303(d) listed waterbodies. See <br />CSWGP Special Condition S8 and Section 5 of this template. <br />Complete the following paragraph for sites that discharge to impaired waterbodies for fine <br />sediment, turbidity, phosphorus, or pH: <br />There are no nearby receiving waterbodies that have a 303(d) listing. <br />Site Inspection (4.1) <br />Site inspections will be conducted at least once every calendar week and within 24 hours <br />following any discharge from the site. For sites that are temporarily stabilized and inactive, the <br />required frequency is reduced to once per calendar month. <br />The discharge point(s) are indicated on the Site Map (see Appendix A) and in accordance with <br />the applicable requirements of the CSWGP. <br />Stormwater Quality Sampling (4.2) <br />Turbidity Sampling (4.2.1) <br />Requirements include calibrated turbidity meter or transparency tube to sample site discharges <br />for compliance with the CSWGP. Sampling will be conducted at all discharge points at least <br />once per calendar week. <br />Method for sampling turbidity: <br />Table 8 — Turbidity Sampling Method <br />Meter/Turbidimeter (required for disturbances 5 acres or greater in size) <br />MxTurbidity <br />Transparency Tube (option for disturbances less than 1 acre and up to 5 acres in size) <br />
