5. Describe inspection results and remedial actions taken in the site log book and in discharge <br /> monitoring reports as described in Section 7.0 of this SWPPP. <br /> 6.2.2 pH Sampling <br /> Stormwater runoff will be monitored for pH starting on the first day of any activity that includes more <br /> than 40 yards of poured or recycled concrete,or after the application of"Engineered Soils" such as, <br /> Portland cement treated base, cement kiln dust,or fly ash. This does not include fertilizers. For <br /> concrete work, pH monitoring will start the day concrete is poured and continue until the last pour. For <br /> engineered soils,the pH monitoring period begins when engineered soils are first exposed to <br /> precipitation and continue until the area is fully stabilized. <br /> Stormwater samples will be collected daily from all points of discharge from site and measured for pH <br /> using a calibrated pH meter test kit, or wide range pH indicator paper. If the measured pH is 8.5 or <br /> greater,the following steps will be conducted: <br /> 1. Prevent the high pH water from entering storm drains or surface safer. <br /> 2. Adjust or neutralize the high pH water if necessary, using appropriate technology such as CO2 <br /> sparging(liquid or dry ice). <br /> 3. Contact Ecology if chemical treatment other than CO2 sparging is planned. <br /> 7.0 REPORTING AND RECORDKEEPING <br /> 1. Site Log Book <br /> A site log book will be maintained for all on-site construction activities and will include: <br /> • A record of the implementation of the C-SWPPP and other permit requirements. <br /> • Site inspections; and' <br /> • Stormwater quality monitoring. <br /> For convenience,the inspection form and water quality monitoring forms included in this C-SWPPP <br /> include the required information for the site log book. <br /> The site log book shall be maintained and retained near and readily accessible to the project for the <br /> life of the project. <br /> 20 <br />
