The gas monitoring and corresponding report was completed by AECOM Technical Services, Inc. for Waste Management Disposal Services of Colorado, Inc. The gas report contains monitoring results from the Phase 1 and 2 perimeter soil gas probes GP-6, GP-7, GP-10 through GP-20, and structure probes GP-1 and GP-2 and inside the shop and office. The gas monitoring report indicates that combustible gas was not detected in any perimeter probes or on-site structures above regulatory limits.

Therefore, the equation found in 40 CFR 60.754(a)(ii)was used-to determine NMOC emission rates for the Annual Tier-1 NMOC Emission Rate Report. • 'MNMoc=2LOR(e ke-e kt)(CNMoc)(3.6 x 101 NMOC Emission Rate'-20061 :2008 MNMoc = Mass methane generation potential, M3/Mg Lo = Refuse methane generation potential, m3/Mg = 170.00 R = Average annual acceptance rate, Mg/yr = 117,246.05 k = Methane generation rate constant, 1/yr = 0.02 c-- = Years since.closure,_yrs_ ____ _ _____ _ 0.00 __ _ - (c= 0 for active and/or new landfills) • t = Age of landfill,yrs = 16.66 CNMoc = Concentration of NMOC, ppm as hexane = 153.00 Conversion factor = 3.6 x 10-9 MNMoc=2(170)(73,002.26)(e40.0280)-e10.02111e.se1)(153.00)(3.6 x 10"9) _ . 6.22 Information used to determine annual average acceptance rate The average annual acceptance rate(R) is based on waste in place as of 10/31/08 divided by 16.66 years (age of site at time of volume measurement) less inert material3.Waste in place is tracked monthly on the North Weld Sanitary Landfill Title V Log by compiling monthly waste received and subtracting inert material volumes. Waste in place(Mg)thru 10/31/08 3,685,508.00 Waste in place less inert and soil(Mg) 1,953,319.24 Percent inert 0.47 Age of site at volume measurement 16.66 Annual average acceptance rate(Mg/yr) 117,246.05 2 For regulatory purposes,the EPA default values for Lo and CNMOC must be used to calculate Tier 1 NMOC emission rates unless actual values have been obtained during Tier 2 sampling. NWLF conducted Tier 2 site specific sampling far CNMoc in 2008(using Method 25C)with a resulting concentration of 153 ppmV as hexane. 3 Inert material includes inert wastes that are disposed in the landfill as well as intermediate and final cover soil used as part of routine landfill cell development. NOTE: These calculations are made for NSPS purposes only. EPA has specifically stated as follows:"It is recommended that these default values not be used for estimating landfill emissions for purposes other than NSPS and EG" (61 FR 9905,9912,March 12, 1996). Consequently,these emissions calculations grossly overestimate actual and potential emissions and reviewers of this document are specifically cautioned against improper and Irresponsible uses of these calculations.

(formerly Earth Tech; Inc.): Sampling for the event occurred on September 29 and 30, 2008. Samples were submitted to TestAmerica Laboratories, Inc. for laboratory analyses. Also enclosed is a 3.5-inch disk, which contains the analytical results for the second annual 2008 sampling event as requested by the Colorado Department of Public Health and Environment. This was the twenty-fifth detection-sampling event for these wells and there were no volatile organic compound detections during this event. Statistical analyses were performed using Intra-well Combined Shewart-Cumulative Sum(CUSUM) Control Charts for wells MW03,MW04,MW05,MW10, and MW12. The enclosed results of the statistical analysis are displayed in tabular and graphical format. The background period for the control charts currently includes data through June 2008;and CUSUM is currently calculated starting at the end of the background period. The statistical evaluation performed as part of the first 2008 event showed no statistical exceedances that were pending verification sampling as part of the second 2008 semi-annual sampling event. There were no control limit exceedances in any downgradient wells during the second 2008 sampling event's statistical analysis. Upgradient well MW03,which had previously shown exceedarices for sulfate and calcium, showed no exceedances during this event.

The insured amount is based on the NWLF Financial Assurance Plan as revised March 2007 and the adjustment below. Section 1.8.3 (C)of the Colorado Regulations Pertaining to Solid Waste Disposal Sites and Facilities, 6CCR-1007-2,requires an annual adjustment to the closure and post-closure financial assurance cost estimate by using the implicit price deflator(IPD)for the gross domestic product. The IPD for 2008 is 1.027 as confirmed with the Colorado Department of Public Health and Environment. The financial assurance cost estimate for 2007 was$2,639,641. The 2008 cost estimate is the 2007 estimate multiplied by the IPD as provided below: $2,639,641 x 1.027=$2,710,910 The enclosed insurance certificate reflects this adjustment to the NWLF financial assurance cost estimate and has been placed in the facility operating record.
