If compliance monitoring of the floor joint in the Animal Shelter storage room exceeds <br />the action level, the storage room door will be removed to increase ventilation. <br />If measurements exceed the proposed 100 ppm (methane) action level in spite of efforts to seal <br />the source of gas infiltration in the Animal Shelter, corrective measures will be developed and <br />evaluated. This evaluation would take into account the explosion and toxic risk presented by <br />the gas, the probability of success, and time and cost to implement. Measures could include <br />localized vacuum extraction wells to reduce the presence of LFG in the vicinity of the Animal <br />Shelter. <br />3.4.2 TRANSFER STATION <br />3.4.2.1 Sampling and Inspection Plan <br />The Snohomish County Solid Waste Division (SCSWD) has placed full time landfill gas monitors <br />within the lunchroom and scale house. The City will have a trained, qualified technician conduct <br />periodic sampling and inspection of the transfer station lunchroom. The technician will use an <br />appropriate methane detection field instrument capable of accurately measuring concentrations <br />down to less than five ppm. <br />The City will provide the SCSWD a copy of this Compliance Monitoring Plan. The SCSWD may <br />provide additional monitoring at its transfer station facility beyond that presented in this <br />Compliance Monitoring Plan. <br />3.4.2.2 Frequency of Sampling <br />The normal frequency for monitoring by the City will be quarterly. More frequent monitoring will <br />be initiated as described below if a contingency trigger is hit. <br />3.4.2.3 Evaluation Methods <br />The continuous in -building alarm system will activate at a flammable gas concentration of 1,000 <br />ppm. Activation of the alarm will cause employees to notify the SCSWD, the Everett Public <br />Works Department and the Fire Department and evacuate the building. <br />The monitoring technician will note and record the readings of the monitoring instrument. <br />SCSWD will be advised of the results from these readings. <br />3.4.2.4 Reporting Requirements <br />Results of Compliance Monitoring will be provided to the SCSWD within 2 business days of <br />sampling. <br />The City will transmit compliance monitoring results and status of corrective actions to Ecology <br />on a monthly basis until the MTCA Cleanup Action Plan and Consent Decree are finalized. <br />Thereafter, the SCSWD will transmit the results to the City on a monthly basis. The City will <br />report results to Ecology on an annual basis. <br />FAprojects\COEv-BR Everett Landfill\PDF maker - final docs\Compliance Compliance Monitoring and Contingency Plan <br />Monitoring Plan\CMCP 1 1-10-00.doc p 9 9 Y <br />FINAL - March 2001 Page 3-5 <br />
