1 <br />1 <br />I <br />1 <br />1 <br />1 <br />1 <br />The City of Everett <br />The Floyd & Snider Team Everett Landfill/Tire Fire Site <br />occurs in a zone identified for pile restrictions. If such pile installation occurs, the ten-year <br />minimum Performance Monitoring requirement will be reset following pile installation. <br />All phases of Performance Monitoring will occur semi-annually during periods of seasonal high <br />and low groundwater levels. <br />4.5.3 REPORTING REQUIREMENTS <br />A Performance Monitoring report will be prepared annually that describes monitoring results and <br />includes all the data collected during the year. Each Performance Monitoring annual report will <br />consist of copies of the validated laboratory data, a summary table of the validated data, a table <br />showing water level monitoring data, a statistical summary of the data, and a cover letter that <br />describes the evaluation of the data. The annual report will be submitted to Ecology. <br />4.6 CONFIRMATIONAL MONITORING <br />The objective of Confirmational Monitoring is to confirm the long-term effectiveness of the <br />cleanup action once cleanup levels have been met [(WAC 173-340-410(1)(c)]. Confirmational <br />Monitoring will consist of semi-annual water quality monitoring, water level monitoring and <br />bi-annual reporting. <br />4.6.1 CONFIRMATIONAL MONITORING PLAN <br />Following completion of Performance Monitoring, the groundwater monitoring well network will <br />be re-evaluated to select appropriate Confirmational Monitoring wells for the Confirmational <br />Monitoring period. A Confirmational Monitoring sampling and analysis plan will be prepared that <br />details sampling parameters, monitoring wells and data evaluation. <br />If the Confirmational Monitoring period is interrupted due to the first significant pile installation <br />during site development activities, Performance Monitoring will be reinstated. Revisions to the <br />Confirmational Monitoring sampling and analysis plan may be necessary to ensure adequate <br />groundwater monitoring downgradient of pile installations. Any further reinstatement of <br />Performance Monitoring will require a review of and update to the sampling and analysis plan. <br />4.6.2 CONFIRMATIONAL MONITORING SCHEDULE <br />Confirmational Monitoring will occur semi-annually, during periods of seasonal high and low <br />groundwater levels, for a minimum of 10 years. If the site's first pile installation event occurs <br />during Confirmational Monitoring, Performance Monitoring will be reinstated. Confirmational <br />Monitoring would recommence after a minimum of ten years of Performance Monitoring, or until <br />cleanup standards are met. In such a situation, the ten-year minimum period for Confirmational <br />Monitoring would be reset. <br />FAprojompli Oce M Everett LandfiMCP maker - final Compliance Monitoring and Contingency Plan <br />docslCompliance Monitoring PIan1CMCP 11-10-t)D.doc <br />FINAL - March 2001 Page 4-9 <br />
