A new monitoring well MW-16 which is scheduled to be drilled and completed approximately 2Q0feet north of well MW-6, has been included in the sampling list. In addition, well LF-2 has been included. Water levels will be measured in all monitoring vmeDo at the |omdfi|| prior to purging the wells for sampling, In addition, water levels will also be measured in vve||8 K0VV-7B. M\8-813, and MW-9B. Field parameter measurements including temperature, pH. and SC will be collected at each well during and at the conclusion of purging. This will be done to insure that formation water is being collected when sampling is conducted. Dissolved oxygen (D{}) and oxidation-reduction potential ({JRP) data will also be collected in the same manner using field multi-meter.

In accordance with the Montana Department of Environmental Quality (DEQ) approval letter dated May 31, 1996, water samples collected in June monitoring events will be analyzed for the '^Fu|| /\m8|y8is" (Table 3 in Tetra Tech'a Groundwater Monitoring Sampling and Analysis Plan) and "Partial Analysis" (Table 4 in Tetra Teoh`s Groundwater Monitoring Sampling and Analysis Plan). Samples collected from seven monitoring wells: WYVV-4' K4VV-5, K8VV'8, KHV\­7A, M\8-8A, [WVV-04, and LF-3 will undergo the "Partial Analysis". Samples collected from the remaining vvmUs/siteow@U be submitted for the "Full Analysis" that could include up to 16 metals. Both Partial and Full Analysis are inclusive of the constituent list in Appendix 1, 40 CFR Part 258 (July 1, 2008) in ARM 17.50.1300 plus chloride, sulfate, nitrG1e/nitrihe, pH, conductivity, anddich/0rndiOuonornethane. Two QA/QC samples will be collected/prepared for the June 2012 assessment monitoring event: 1> A duplicate sample will be collected from a dovVnQnadieAt monitoring well and submitted for analysis of volatile organic constituents listed in Tetra Tenh'e Table 3 and 2) A trip blank will be prepared in the laboratory, shipped to the sampling crew with the sample bott|es, and returned to the laboratory for analysis of volatile organic constituents listed in Tetra Tech'sTable 3. Page 2of4 Landfill Gas Sample Collection and Analysis Two landfill gas sample oO|k*otion and analysis events will be conducted at the landfill gas extraction system (UGES) flare during the groundwater monitoring events (in December 2O11 and June 2012). This will be for the purpose of demonstrating compliance with the air quality permit. In each monitoring event, o Tetra Tech scientist will fill two Ted|ero sammpKe 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 | of Air Quality Permit#28b1-DO. 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. Groundwater Monitoring Reporting and Project Management There will be two |ave|u of reporting following the December 2011 and Juno 2012 groundwater monitoring events. The first level of reporting will be one page reports, summarizing the results of the monitoring, sent to DECJ departments fo||mvviD0 receipt of laboratory reports from landfill gas and groundwater sample collection events. The one page, letter reports will be sent to [}EQ Air Resources Management—Air Compliance Section and [}EQ Solid Waste Regulatory Program, The second level of reporting will be the preparation of groundwater monitoring report following each of the two groundwater monitoring events. The report will summarize the results of the monitoring including activities undertaken, monitoring methods, results, limited data an@k/�|o, and statistical analysis. Data and statistical analysis will also beconducted in acoordanco-with TetrgTeoh's Groundwater Monitoring Sampling and Analysis Plan.
