SAMPLING PROTOWFOR ROUTINE PIPING/ DISPENSERWOVAL/REPLACEMENT <br />The following represents minimum sampling criterion required for closure compliance. Soil samples ollected shall <br />be representative of native soils beneath the tank's invert (tank's bottom) at a collection depth no to exceed 2 - 4 <br />feet. If contamination is documented during closure, an Unauthorized Release Notification mus e completed <br />and submitted withing five (5) working days pursuant to California Health & Safety Code, Se 'on 25295. <br />DISPENSER SAMPLES <br />AT LEAST ONE SAMPLE BELOW EACH <br />PIPING AND STOCKPILE <br />PIPING SOIL SAMPLES <br />1 Sample every 20 lineal feet <br />DISPENSER & PIPING STOCKPILE SAMPLES <br />2 Samples every 50 cubic yards <br />MINIMUM VERIFICATION LOORATORY ANALYSIS <br />All analysis methods are th designated EPA methods described in EPA SW 846, Third Edition.
