January Update on Recent Activities at APAC-Reno
|
Week ending January 7, 2006APAC-Reno has drilled three additional wells as part of the landfill gas collection system during the past week. 18 landfill gas wells have been installed to date. APAC is planning to begin construction of the gas collection system. APAC-Reno has installed five perimeter air monitors for continuous air sampling for H2S gas. JCED is collecting the data from each air monitor and all downloaded information is shared with the designated agencies. APAC-Reno will continue to conduct source monitoring with a hand-held H2S monitor until three additional continuous monitors are installed inside the landfill. APAC-Reno and their consultant are working with KDHE-Bureau of Water to manage the contact water within the fill area through the water discharge permit revision process. The permit is called a NPDES permit which stands for National Pollutant Discharge Elimination System. Sulfide levels in the west seep draining contact water into the lower east pond continue to decline. APAC-Reno and their consultant are preparing the hydrogeologic investigation report and hope to submit the report by mid-January. The intermediate cover is approximately 70% completed over the south part of the landfill. Week ending January 21, 2006APAC-Reno installed the final gas well as part of the landfill gas collection system. The pipeline system to connect the gas wells is expected to take 2-3 weeks to construct. APAC-Reno continues to treat the contact water collected in the lower east pond with hydrogen peroxide and caustic. The west and south seeps continue flowing at 15 gallons per minute each. A meeting is scheduled early next week with the KDHE-Bureau of Water to discuss revisions to the landfill NPDES permit. With a revised National Pollutant Discharge Elimination System (NPDES) permit, APAC-Reno will try and increase flow from the west and south seeps to speed up the dewatering process. The perimeter air monitoring H2S meters are operating and the data is being collected and downloaded by JCED. The H2S monitors to be placed inside the landfill have been received and are undergoing trial runs with the telemetry system to insure the alarm system works. They should be set next week. No reported problems with perimeter monitors have occurred to date. The intermediate cover construction continued through Thursday and should be completed early next week covering over the southern landfill areas. The Hydrogeologic Investigation Site Report was submitted to the Kansas Department of Health and Environment on Wednesday, 1/18/06. Week ending January 28, 2006Welding on the piping for the APAC-Reno landfill gas collection
system has begun this week to connect the landfill gas wells.
Approximately 2000 ft. of 6 inch line was completed. The vacuum blower
is to be delivered about 2/11/06. The trenching for the gas lines will
begin Monday. APAC continues to treat contact fill water drained into the lower
east pond with caustic and hydrogen peroxide liquid. APAC and their
consultant have met with the Kansas Department of Health and Environment
(KDHE) Bureau of Water (BOW) and other KDHE representatives to discuss
revising their water discharge permit. The BOW will advise them on
effluent standards for discharge of contact water. The appropriate H2S monitors have been installed inside the
landfill boundaries and are operating. A telemetry system for detecting
high H2S levels with alarm notification should be online in early
February. Perimeter air monitors continue operation with periodic
downloads by Environmental Department (JCED) staff. All intermediate cover should be in place by Monday, 1/30/06. The hydrogeologic investigation report has been submitted including the final analysis on groundwater wells. The report is under review by JCED and KDHE. Preliminary review of the report field data shows no evidence of offsite groundwater contamination from the landfill waste mass.
