Home My WebLink About12- Tetra Tech Amendment to Professional Services Agreement for continued post-closure ground water monitoring at Story Mill LandfillTASK ORDER DECEMBER 2012 AND JUNE 2013 ASSESSMENT MONITORING AND OTHER SERVICES BOZEMAN SANITARY LANDFILL CLIENT: The City of Bozeman P.O. Box 1230 Bozeman, Montana 59711 -1230 November 9, 2012 CONSULTANT: Tetra Tech, Inc. 851 Bridger Drive, Ste 6 Helena, MT 59715 Attention: Mr. Dustin Johnson Attention: Mr. Mark F. Pearson SCOPE OF SERVICES: Groundwater Monitoring: Two 'Assessment' groundwater monitoring events will be scheduled. These will be conducted in December 2012 and June 2013. Tetra Tech will perform groundwater monitoring in accordance with Tetra Tech's Groundwater Monitoring Sampling Analysis Plan (September 17, 2010) for the landfill. Groundwater sites to be monitored includel3 monitoring wells (MW -4, MW -5, MW -6, MW -7A, MW -8A, MW -9A, MW -10, MW -11, MW -12, MW -13, MW -14, MW -15, and LF -3) and two private water sources (Mcllhattan Seep and Mcllhattan Veterinary Clinic well). In the past several monitoring events, the Department of Environmental Quality (DEQ) has required that five additional wells (LF -2, MW -7B, MW -8B, MW -9B, and Shop Well (adjacent to the Bozeman Landfill Shop)) be monitored and samples collected for analysis. In addition, three new groundwater wells (MW -6B, MW -8C, and MW -16) were drilled and completed in May 2012. These new wells were monitored and samples collected in June 2012. This task order assumes that 23 wells /sites will be monitored and sampled. A sampling and analysis matrix is presented in Table 1 of Attachment A contained in this task order. December 2012 Assessment Monitoring Monitoring and collection of water samples will be conducted in 21 monitoring wells (MW -4, MW- 5, MW -6, MW -6B, MW -7A, MW -7B, MW -8A, MW -8B, MW -8C, MW -9A, MW -913, MW -10, MW -11, MW -12, MW -13, MW -14, MW -15, MW -16, LF -2, LF -3, and Shop Well) and two private water sources (Mcllhattan Seep and Valley View Veterinary Clinic well). Water levels will be measured in all monitoring wells at the landfill prior to purging the wells for sampling. Field parameters including temperature, pH, and specific conductivity will be measured at all stations. Field parameters will be measured during and at the conclusion of purging the wells. For the purposes of this task order, the purchase of a dedicated pump is included in the event of breakdown of one of the dedicated well purging /sampling pumps. Water samples collected will be analyzed by Pace Analytical Laboratories (in Billings, Montana) for many of the constituents listed in Appendix I, 40 CFR Part 258 (July 1, 2008) in ARM 17.50.1306 plus chloride, sulfate, nitrate /nitrite as N, pH, conductivity, iron, vanadium, zinc, and dichlorodifluoromethane. Therefore, every sample will be submitted for the "Full Analysis" that includes 15 metals (Table 3 in Tetra Tech's Groundwater Monitoring Sampling and Analysis Plan). Table 3 is contained in Attachment A. Well samples where only volatile organic compounds (VOCs) and nitrate + nitrite as N would be analyzed are indicated in Table 1. Page 1 of 4 Two quality assurance /quality control (QA/QC) samples will be collected and prepared during the December 2012 assessment monitoring event. These will be 1) A duplicate sample collected and submitted for analysis of all constituents included in Table 3 of Tetra Tech's Groundwater Monitoring Sampling and Analysis Plan and 2) A trip blank prepared by the analytical laboratory, shipped with the sample bottles, travelling with sample bottles in the field, and returned to the laboratory for analysis of VOCs. June 2013 Assessment Monitoring Monitoring and collection of water samples will be conducted in 21 monitoring wells (MW -4, MW- 5, MW -6, MW -6B, MW -7A, MW -7B, MW -8A, MW -8B, MW -8C, MW -9A, MW -9B, MW -10, MW -11, MW -12, MW -13, MW -14, MW -15, MW -16, LF -2, LF -3, and Shop Well) and two private water sources (Mcllhattan Seep and Mcllhattan Veterinary Clinic well). Water levels will be measured in all monitoring wells at the landfill prior to purging the wells for sampling. Field parameters including temperature, pH, and specific conductivity will be measured during purging. These parameters and dissolved oxygen and oxidation reduction potential will be measured at the conclusion of purging. In accordance with the DEQ approval letter dated May 31, 1996, water samples collected from designated wells in June monitoring events will be analyzed for the "Full Analysis" (Table 3 in Tetra Tech's Groundwater Monitoring Sampling and Analysis Plan) and "Partial Analysis" (Table 4 in Tetra Tech's Groundwater Monitoring Sampling and Analysis Plan). Tables 3 and 4 are contained in Attachment A. Therefore, samples collected from seven monitoring wells: MW -4, MW -5, MW -6, MW -7A, MW -8A, MW -9A, and LF -3 will undergo the "Partial Analysis" (Table 4). Samples collected from the remaining wells /sites will be submitted for the "Full Analysis" that includes 16 metals (Table 3). Both Partial and Full Analysis are inclusive of the constituent list in Appendix I, 40 CFR Part 258 (July 1, 2008) in ARM 17.50.1306 plus chloride, sulfate, nitrate /nitrite as N, pH, conductivity, and dichlorodifluoromethane. Two QA/QC samples will be collected and prepared during the June 2013 assessment monitoring event: 1) A duplicate sample will be collected from a downgradient monitoring well and analyzed for the "Full Analysis" (Table 3). A trip blank will be prepared in the laboratory, shipped to the sampling crew with the sample bottles, and returned to the laboratory for analysis of VOCs listed in Table 3. Other Services: Other environmental services include monitoring and maintenance of the components of the landfill gas extraction (LGE) system, additional field work or monitoring as needed, regulatory liaison as needed, and reporting and project management. Landfill Gas Sample Collection and Analysis Two landfill gas sample collection and analysis events will be conducted at the LGE system flare during the groundwater monitoring events (in December 2012 and June 2013). This will be for the purpose of demonstrating compliance with the air quality permit. In each monitoring event, a Tetra Tech scientist will conduct monitoring of the LGE system at the flare and then fill two Tedlar® sample bags with landfill gas from an access port located between the blower and flare. Each sample will be submitted for laboratory analysis of parameters listed in Table 1 of Air Quality Permit # 2951 -00. Upon receiving the landfill gas analytical results, Tetra Tech will forward a copy of the lab report to the City and DEQ - Air and Waste Management Bureau. Page 2 of 4 Additional Services Additional field and reporting services include the following: • Monthly monitoring of perimeter landfill gas probes for methane and other gas concentrations • Monthly monitoring of flare operation and gas concentrations • Inspection and monitoring of the landfill gas extraction (LGE) well heads • Any light maintenance needs associated with the flare or LGE system or miscellaneous field work • Additional groundwater monitoring that cannot be covered under assessment monitoring budgets • Any regulatory liaison and reporting services requested by City of Bozeman Further explanation of Tetra Tech's services is contained in the Estimated Budget in Attachment B. Reporting and Project Management There will be two levels of reporting following the December 2012 and June 2013 groundwater monitoring events. The first level of reporting will be one page reports, summarizing the results of the monitoring, sent to DEQ departments following receipt of laboratory reports from landfill gas and groundwater sample collection events. The one page, letter reports will be sent to DEQ Air Resources Management — Air Compliance Section and DEQ Solid Waste Regulatory Program. The second level of reporting will be the preparation of a groundwater monitoring report following each of the two groundwater monitoring events. This will include entry of data into the project database. The report will summarize the results of the monitoring including activities undertaken, monitoring methods, results, limited data analysis, and statistical analysis. Data and statistical analysis will also be conducted in accordance with Tetra Tech's Groundwater Monitoring Sampling and Analysis Plan. The report will be submitted as a draft version to the City of Bozeman for review and comment. Tetra Tech will incorporate any changes or comments requested by the City and finalize the report. Upon receiving approval from the City, the final report will then be forwarded to DEQ Solid Waste Regulatory Program as a full or partial paper copy and an electronic copy. The paper copy to the DEQ will include report text, figures, summary tables, time series plots, and plots of statistical results. Project management will consist of scheduling of field events; review of invoicing and budget; and communication with the City of Bozeman, DEQ, analytical laboratory personnel, and other pertinent parties. Project management will also include preparation of the succeeding monitoring task order anticipated in November 2013. PERIOD OF PERFORMANCE: Activities covered in this task order will begin on December 1, 2012 and continue through November 30, 2013. Groundwater monitoring activities will be performed during December 2012 and June 2013. Data analysis and report preparation will follow the conclusion of each of the monitoring events and receipt of laboratory results. Each monitoring report will be submitted to the City within eight weeks of receiving the final laboratory report. Following review and approval of the draft report by the City, each report will be finalized and submitted to DEQ within two weeks of receipt of comments from the City and no later than 90 days from completion of groundwater sampling.
