Questions regarding this RFP may be directed to the Citys Contract Project Manager - Angela Frost, at Angela.Frost@Lincolnca.gov. Question Deadline 07/20/2022 at 5:00 PM CT The City of Lincoln is now accepting bids for the Closed Landfill Monitoring project. The selected vendor will monitor the closed landfill in the City of Lincoln in accordance with the requirements specified in the RFP. See attached RFP for full details. Scope of Services: 1. Compliance Monitoring as required by WDR R5-2003-0142 including but not limited to: a. Winterization Inspection and Report i. Travel to the Site annually, prior to the rainy season but no later than September 30, to perform a Site inspection for the purpose of winterizing the Site. The inspection shall identify damage to the landfill cover, grade, precipitation and drainage controls, access roads, and other Site facilities. Coordinate with the City any needed repairs, then prepare a report documenting winterization activities. b. Semi-Annual Monitoring and Reporting, Second Half 2022 through Second Half 2027 i. As required by the WDRs, Order Number R5-2003-0142, perform Semi- Annual Monitoring at the Closed Lincoln Landfill beginning with the Second Half of 2022 and continuing through the Second Half of 2027. ii. Travel to the Site on a quarterly basis and collect depth to groundwater data. This data will be used to calculate groundwater gradient and direction of flow. Once during each Semi-Annual reporting period, purge all seventeen wells of a minimum of three well volumes (or until dry) while collecting temperature, pH, conductivity and turbidity readings of the purge water. The purge water will be disposed of into the City of Lincoln's sanitary sewer system. Water samples will be collected from all seventeen wells and the two surface water sampling points along Auburn Ravine. Samples will be analyzed as per the Monitoring and Reporting Program (MRP) of the WDRs. iii. Upon receipt of the analytical data, a semi-annual report will be prepared including the following information: 1. The results of groundwater elevation monitoring; 2. Tabular summaries of corrective action monitoring data showing sampling dates, well constituents, concentrations, concentration limit, and units. The data shall be presented so as to clearly show historical concentrations at each well. The table shall also clearly show whether new monitoring data exceedances occurred during the monitoring period; 3. Contaminant contour maps of representative corrective action monitoring data, showing the estimated extent of the contaminant plume; 4. Plots, graphical summaries and narrative discussion of the results of correction action monitoring; 5. A compliance evaluation summary for the monitoring period; 6. Field and laboratory tests sheets; and, 7. An electronic copy of the data in PDF format. iv. Also included in this task are the costs necessary to comply with Assembly Bill 2886 (Uploading data into the GeoTracker data base). c. Semi-Annual Monitoring with the Constituents of Concern Five Year Report, Second Half of 2022 through Second Half of 2027 i. As required by the WDRs, Order Number R5-2003-0142, perform Semi- Annual Monitoring and Reporting beginning the Second Half of 2022 and continuing through the Second Half of 2027 with the Constituents of Concern Five Year Report for all wells. ii. Travel to the Site on a quarterly basis and collect depth to groundwater data. This data will be used to calculate groundwater gradient and direction of flow. Once during each Semi-Annual reporting period, purge all 17 wells of a minimum of three well volumes (or until dry) while collecting temperature, pH, conductivity and turbidity readings of the purge water. Purge water will be disposed of into the City of Lincoln's sanitary sewer system. Collect water samples from the existing eleven wells and the two surface water sampling points along Auburn Ravine. Samples will be analyze as outlined in Attachment C in the Monitoring and Reporting Program (MRP) of the WDRs. In addition, samples collected of the six new wells will be analyzed for Constituents of Concern as outlined in Attachment D of WDRs Monitoring and Reporting requirements. iii. Upon receipt of the analytical data, a semi-annual report will be prepared including the following information: 1. A tabular summary of well information from the installation logs, including well name, top of casing elevation, total depth, depths/elevations of screened interval, and the soil type(s) over the screened interval; 2. The results of groundwater elevation monitoring; 3. Tabular summaries of corrective action monitoring data showing sampling dates, well constituents, concentrations, concentration limit, and units. The data shall be presented so as to clearly show historical concentrations at each well. The table shall also clearly show whether new monitoring data exceedances occurred during the monitoring period; 4. Contaminant contour maps of representative corrective action monitoring data, showing the estimated extent of the contaminant plume; 5. Plots, graphical summaries and narrative discussion of theresults of correction action monitoring; 6. A compliance evaluation summary for the monitoring period; 7. Field and laboratory tests sheets; and, 8. An electronic copy of the data in PDF format iv. The report will also include an Annual Monitoring Summary Report. The Annual Monitoring Summary Report will include a summary of the detection and corrective action monitoring results for the prior year and include a discussion of compliance with the WDRs. The report will include both tabular and graphical summaries of the prior year's monitoring data, including time series plots of historical monitoring data for each monitoring parameter/COC. For corrective action monitoring data, the report shall also include the following: 1. A tabular summary of well information from the installation logs, including well name, top of casing elevation, total depth, depths/elevations of screened interval, and the soil type(s) over the screened interval; 2. A summary of the results of trend analysis performed on each constituent of the release during the prior year; 3. A summary of the results of water chemistry analysis of water quality data collected during the prior year, including illustrative graphs and plots (i.e. Stiff diagrams, Trilinear plots; etc.); and, 4. Contaminant contour maps for representative constituents (i.e. TDS and chlorides) constructed as part of semi-annual reporting during the prior year and a discussion as to whether the size of the plume has increased, decreased, or remained the same since the previous monitoring year. v. Also included in this task are the costs necessary to comply with Assembly Bill 2886 (Uploading data into the GeoTracker data base). The method of contractor selection has not been determined at this time.
