Box 3378 San Francisco, CA 94105 Honolulu, HI 96801-3378 Subject: Tier 1 and 2 Annual NMOC Emission Reports West Hawaii Sanitary Landfill New Source Performance Standards Subpart WWW Dear Mr. Kihara and Mr. Salazar: As requested by the United States Environmental Protection Agency (USEPA) Region IX Air Division and State of Hawaii Department of Health (DOH), please find enclosed Annual Non- Methane Organic Compound Emission (NMOC) Reports, Tier 2 NMOC Concentration Analysis Report, and Fixed Gas Sampling and Analysis Report for the West Hawaii Sanitary Landfill (WHSL). The WHSL is owned and operated by the County of Hawaii and is managed under contract by Waste Management of Hawaii, Inc. (WMH). As indicated in our Self-Disclosure Letter, dated August 29, 2005, WMH was unable to locate documentation as to whether a Tier 2 NMOC Analysis was conducted at the WHSL. As a result, WMH conducted and completed a Tier 2 NMOC Analysis at the WHSL in January 2006. WMH was also unable to locate documentation of submittal of Annual NMOC reports for the landfill since 2001. As part of the enclosed reports, WMH has provided Annual NMOC Emission Reports for three periods: 1996 through 2000; 2001 through 2005; and 2006 through 2010. As requested, WMH has calculated Annual NMOC emissions for the period of 1996 through 2001 using Tier 1 methodology. WMH has also calculated Annual NMOC emissions for the period of 2002 through 2005 using Tier 1 and Tier 2 methodologies. The Annual NMOC emissions for the period of 2002 through 2005, calculated using Tier 2 methodology, were less than 4.0 megagrams per year. These NMOC emissions are substantially less than the 50 megagram per year trigger level for designing and installing a Gas Collection and Control System (GCCS). WMH has also projected Annual NMOC emissions to be less than 7.3 megagrams per year for the period of 2006 through 2010, using Tier 2 methodology. These Tier 2 Annual NMOC emissions rates are more than an order of magnitude lower than the Tier 1 Annual NMOC emission rates. This was because the Tier 2 NMOC concentration was determined based on empirical data to be 193 ppmv as hexane versus the default Tier 1 NMOC concentration of 4000 ppmv as hexane. WMH has also determined that rainfall at the WHSL is less than 8 inches per year. Therefore NMOC emissions were determined for arid conditions. Given the low landfill gas generation and NMOC emission rates predicted by the Tier 2 analysis and that grid conditions exist at the site, WMH respectfully requests that installation of a GCCS be deferred until annual NMOC emissions exceed 50 megagrams per ye D APR 2 1 2006 ~ ' t,9SEPA Region IX I-Hawaii Department cif Health ,Q pril 18, 2006 S ubpart WWW. Because of the low predicted gas generation rates from arid conditions as well a~ local conditions, WMH believes that installation and operation of a GCCS at this time would not achieve the standards of Subpart WWW nor provide any environmental benefit. WMH believes that it may be difficult to sustain operation of an active GCCS and maintain Subpart WWW standards (i.e., wellhead, control system operations) with the limited methane gas flows predicted due to the low volume of waste in place and grid conditions until such time as NMOC emissions exceed 50 Megagrams per year. At the request of DOH and US EPA, WMH also performed hydrogen analysis on each of the Tier 2 Samples collected during the Tier 2 sampling event in January 2006. As indicated in that attached Fixed Gas Sampling and Analysis Report, hydrogen was not detected in any of the samples. WMH appreciates careful consideration of its request to defer installation of the GCCS at the WHSL until annual NMOC emissions exceed 50 megagrams per year. Although documentation of the submittal of past Annual NMOC Emission Reports was not located and NMOC emissions calculated using Tier 1 methodology exceeded 50 megagrams per year, the Tier 2 NMOC sampling results provide clear documentation that there are and were no excess emissions and that installation of a GCCS is not required, nor necessary. With the submittal of this report, we believe that all of the submittals required by NSPS Subpart WWW will have been completed for the WHSL. If you need additional information or have any questions, please contact me at 808-668-2985. Sincerely, Paul F. rns Vice PresidenUGeneral Manager Waste Management of Hawaii, Inc.

(Shaw) herein provides the annual Non-Methane Organic Compounds (NMOC) emission rate estimates for 1996 through 2005, and 2006 through 2010 for the West Hawaii Sanitary Landfill (WHSL), located in Waikoloa, Hawaii in accordance with the New Source Performance Standards (NSPS) for Municipal Solid Waste (MSW) Landfills under 40 Code of Federal Regulations (CFR) Part 60, Subpart W W W and State of Hawaii Department of Health (DOH) requirements. The WHSL is owned and operated by the County of Hawaii, and managed under contract by Waste Management of Hawaii, Inc. (WMH). On behalf of WMH, Shaw is submitting these Annual NMOC emission rate estimates for the periods 1996 through 2005 and 2006 through 2010.

Under the NSPS, landfills I which meet certain applicability criteria may be required to design and install a landfill gas I (LFG) collection and control system (GCCS) if the landfill discharges more than 50 megagrams (Mg) (55 tons) of NMOCs per year. An exemption or deferral from this requirement can be obtained by evaluating LFG emissions and demonstrating that emissions are below specified regulatory thresholds. The NMOC emission rate is determined using a three-tiered approach as described in the regulation: I 1. Tier 1: Under Tier 1, a prescribed equation is used to estimate the quantity of ' emissions based on fill volume, inert fraction, acceptance rate, age of waste, and other factors, and using default values as provided by the United States ~ Environmental Protection Agency (USEPA) far NMOC concentration (4,000 parts ' per million by volume [ppmv]) and methane generation potential (170 cubic meters per megagram [m'/Mg]). Please note that these default values are not site- specific, but are based on empirical data from U.S. landfills (USEPA, 2005). Tier 1 emission estimates using these values are believed by the landfill industry to be significantly overestimated. 2. Tier 2: Under Tier 2, the landfill owner/operator can install two sample probes per i hectare (2.471 acres) of landfill surface in areas of waste equal to or greater than two years of age, with a maximum of 50 sample probes, and specifically determine the NMOC concentration. The site-specific measured NMOC concentration and the default methane generation potential are then used to calculate asite-specific ( NMOC emissions rate. If the 50 Mg emissions rate is exceeded, the owner can either install a GCCS or proceed to Tier 3. If emissions are below the 50 Mg limit, an annual (or 5-year) emissions report must be submitted, and testing performed it every five years to demonstrate continued compliance. 3. Tier 3: Tier 3 calls for the installation of three to five gas-extraction wells, a gas exhauster, and temporary controls and flare. Then agas-extraction test is to be performed to measure aaite-specific NMOC generation rate. This value can be used to replace the default refuse decay rate ("k") value in LFG equation. If the i NMOC generation rate exceeds 50 Mg, a GCCS must be installed. If the NMOC generation rate is less than 50 Mg, the owner or operator must submit a periodic NMOC emissions rate report.

Q 4/I SI06 119185 2-1 3 NMOC ESTIMATES (1996-2000) For this report, the USEPA's Landfill Gas Emissions model (LandGEM [Version 3.02J) was used to estimate LFG emissions from the WHSL. LandGEM provides a relatively simple approach to estimating LFG emissions. LandGEM is based on a first-order decomposition rate equation for quantifying emissions from the decomposition of ~ landfilled waste in MSW landfills (LJSEPA, 2005). The site-specific NMOC concentration, actual waste disposal rates from 1993 through December 2004, and projected waste disposal rates from 2005 to closure were input into LandGEM. Actual and projected waste disposal rates were entered into the model by WMH and used in the model runs. The model default Tier 1 methane generation rate constant of 0.02 per ~ year (arid region value) and a methane generation potential "Lo" of 170 m'/Mg were also used. The Tier 1 L andGEM model outputs are included in Attachment 1. Based on LandGEM calculations using the Tier 1 default NMOC concentration of 4,000 ppmv as hexane, the WHSL emission estimates were below the NSPS implementation threshold of 50 Mg NMOC per year between 1996 and 2000. The results of the NMOC estimates for each year are listed in Table 1.

The Tier 1 Annual NMOC rates exceeded the 50 Mg/yr threshold for the years 2002 through 2005, as indicated in Table 2. The Tier 1 LandGEMmodel outputs are included in Attachment 1. ~ The default NMOC value is not site-specific, and Tier 1 emissions are believed by the landfill industry to be overestimated. WMH verified the USEPA default NMOC value i overestimates NMOC emissions for this site by over an order of magnitude. A Tier 2 NMOC Concentration study was conducted by Shaw in January 2006. Based on the results of sampling and analysis, asite-specific NMOC concentration of 193 ppvm as hexane was calculated. The 2002 through 2005 NMOC emission rates were recalculated using the results of this Tier 2 study. The Tier 2 LandGEM model outputs are included in Attachment 3. The NMOC emission estimates using Tier 1 and Tier 2 methodologies are ~ shown in Table 2 below. The results indicate that if a Tier 2 study had been conducted for the period 2002 through 2005, the WHSL would not have exceeded the 50 Mg/yr NMOC emission rate threshold for installation of a GCCS. t I~ i I ESM \ landfil\wm hawaii\wa~ hawaii\Z005 tiu 2\mn4eportaUinal\wm hi nmoc repon final4-~ 5-W Ooc Re. 0, 4/15/06 119185 4- 1 Table 2 Summary of NMOC Emission Rates (2001-2005) West Hawaii Sanitary Landfill NMOC Emission Estimates Year (as Hexane) Tier 1 (Mg/Yr) Tier 2 (Mg/Yr) 2001 48 n/a ` 2002 55 2.7 ~ 2003 63 3.0 2004 71 3.4 2005 82 4.0 l ( Actual and projected waste disposal rates were entered into the model by WMH and used ( in both model runs.

The Tier 2 Sampling, Analysis, and NMOC Concentration report in its entirety is included as Attachment 2. The Tier 2 LandGEM model outputs are included in Attachment 3. 4.2 Estimation of NMOC Concentrations (2006-2010) As a GCCS has not been installed, annual Tier 2 NMOC emission rates for the 5-year period of 2006 through 2010 have also been calculated. These NMOC emission ~ estimates are being submitted to satisfy the NSPS requirement for submittal of NMOC emission estimates until a GCCS is installed and operating. The Tier 2 NMOC emission estimates for the period of 2006 through 2010 were calculated using the results of the January 2006 Tier 2 sampling and are shown in Table 3. Based on model estimates, the WHSL would not exceed NMOC emissions of 50 Mg per year during the five-year period from 2006 through 2010. The highest annual NMOC emission estimate for this time period is 7.3 Mg/yr in 2010.

Therefore, a GCCS would not have been required to be installed. Based on the NMOC concentration results of the Tier 2 study conducted in January 2006 (included in Attachment 2), the annual estimates of NMOC emissions for the five-year period from 2006-2010 indicate that emissions are less than 50 Mg per year for each of the next five years, indicating that the WHSL is not required to design and install a GCCS. Based on the waste disposal rates projected by WMH and the site-specific NMOC i concentration of 193 ppmv as hexane, the maximum NMOC emission over the life of the currently permitted landfill was estimated by LandGEMto be 24.8 Mg per yeaz, to occur in the year 2038. This estimate is less than the 50 Mg per year NSPS threshold requiring ~ GCCS installation at a landfill. l I 4 I~ ES?n \ land(il\wm hau'aidwes\ hawaiip005 tier 2VexMeports\Gnal\wae hi nmoc mpon final <-6-Ofi doc Rem 0, 4A 5/W 119185 5-1 6 REFERENCES USEPA, 2005.

The software provides a relatively simple approach to estimating landfll gas emissions. Model defaults are based on empirical data from U.S. landfills. Field test data can also be used in place of model defaults when available. Further guidance on ' EPA test methods, Clean Air Act (CAA) regulations, and other guidance regarding landfill gas emissions and control technology requirements can be found at http://www.epa.gov/ttnatw0l/landfill/landflpg.html. LandGEM is considered a screening tool -the better the input data, the better the estimates. Often, there are limitations with the available data regarding waste quantity and composition, variation in design and operating practices over time, and changes occurring over lime that impact the emissions potential. Changes to landfill operation, such as operating under wet conditions through leachate recirculation or other liquid additions, will result in generating more gas at a faster rate. Defaults for estimating emissions for this type of operation are being developed to include in LandGEM along with defaults for convential landfills (no leachate or liquid additions) for developing emission inventories and determining CAA applicability.

(Shaw) herein provides a summary report on New Source Performance Standards (NSPS) Tier 2 sampling, analysis, and calculations to estimate the current nonmethane organic compounds (NMOC) concentration for West Hawaii Sanitary Landfill (WHSL), located in Waikoloa, Hawaii. Summaries of the regulatory background, rational for implementation of the Tier 2 analysis, field sampling activities, laboratory analysis, and correction calculations are described in this report. The WHSL is owned and operated by the County of Hawaii, and managed under contract by Waste Management of Hawaii, Ina (WMH). WMH is submitting this report to the State of Hawaii Department of Health (DOH) Clean Air Branch and the United States ~ Environmental Protection Agency (USEPA) Region IX Air Division to establish landfill gas (LFG) regulatory compliance at the WHSL in accordance with the New Source ~ Performance Standards (NSPS) for Municipal Solid Waste (MSW) Landfills (NSPS) Subpart WWW, 40 CFR §60.757(b)(1)(i)(A).

An exemption or deferral from this requirement can be obtained by I evaluating LFG emissions and demonstrating that emissions are below specific regulatory thresholds. ~ The WHSL is considered a "new" landfill under the NSPS, because it began accepting waste after May 30, 1991. "New" landfills were required to provide NMOC emission estimates using a tiered calculation program defined in the NSPS. Tier 1 emission rate ~ calculations are based on U.S. Environmental Protection Agency (USEPA) default values for LFG generation and NMOC concentration (4,000 parts per million by volume [ppmv]). These default values are not site-specific, and Tier 1 emission estimates are believed by the landfill industry to be significantly overestimated. An NSPS Tier 2 testing program allows the determination, through sampling and analysis of LFG, of a site specific NMOC concentration. The site-specific value can then be used in the USEPA's emission rate equation in lieu of the Tier 1 default value, and a new NMOC emission rate can be calculated. Reporting of the projected Tier 2 emission rate { calculation is available for WHSL for afive-year period following the determination of a I site-specific NMOC concentration, if the values do not exceed the NSPS implementation threshold of 50 Mg. per year. 1 ~ This Tier 2 study was conducted to demonstrate that site specific NMOC concentrations are substantially less than the Tier 1 default NMOC concentration of 4,000 ppmv as hexane.

' In accordance with the NSPS requirements, sample locations were placed on a grid at a minimum frequency of two per hectare in areas of waste equal to or greater than two years of age. Approximately 13.1 hectares (fill cells 1 through 6) contain emplaced refuse that is older than 2 years. Thus a total of 9 composite LFG samples from 26 sample locations were collected for analysis. Samples were taken at a depth of j approximately five (5) feet using a hydraulically driven, direct-push sampling rig ~ equipped with stainless steel sampling rods. A site plan showing the approximate sampling locations is provided as Figure 1. The 26 LFG samples were combined into nine SUMMA canisters per Shaw's modified USEPA Method 25C procedures as submitted to the USEPA in the January 2006 Tier 2 Work Plan included in Appendix A. The samples were transferred to Air Technologies Laboratories, Ina (ATL, City of Industry, CA) for analysis under USEPA Methods 3C and 25C. LFG field sampling forms, which document the sampling procedures, are provided in Appendix B. A summary of Method 25C-applicable field sampling conditions is also provided in Appendix B. t ESM\landfnwm hawau\wesi hawaii~2o0s her 2\¢rzNeponsVnanwm.ni tieR COncenvalnn report 4-6-Ob doc Rev.O, DA VOn news 3-1 i 4 SUMMARY OF LABORATORY ANALYTICAL RESULTS All laboratory analyses were performed by ATL. Following laboratory analysis, NMOC i concentrations were calculated from raw laboratory analytical data in accordance with USEPA Methods 25C and 3C. Laboratory calculations included Method 25C corrections ' for sampling temperature, final canister pressure, moisture and nitrogen content. Shaw's 4 calculations consisted of conversion of analytical results to "as hexane" from "as methane", and determination of the sample-weighted average NMOC concentration for the WHSL. A summary of laboratory analytical results is shown in Table 1. A review of the laboratory results indicate Sample 02 should be a "voided sample" due to nitrogen and oxygen entrainment exceeding the NSPS maximum allowable concentrations (20 and 5 percent by volume, respectively). It should also be noted that the NMOC concentration in Sample 02 is also a statistical outlier. 'The NMOC concentration in Sample 02 was approximately 19 times the average concentration of the rest of the samples, and over 8 times the next highest sample concentration. The most probable cause for the elevated NMOC concentration is a localized source (e.g. container) of residua] NMOCs (e.g. fuel or paint) at one of the three sampling points. 1n fact, the field instrument methane reading at probe hole location TP22 was 99.9 percent, indicating the presence of an unidentified interfering compound. No other probe hole location had an anomalous field methane reading. Due to both Method 25C requirements and the fact that this localized point source is an i anomaly, Sample 02 has been removed from calculating the site's average NMOC concentration. An adjusted weighted average calculation was applied over the remainder of the sample canisters to compensate for the removal of Sample 02, as shown in Table 1. The adjusted weighted average was the sum of the eight acceptable composite cannister NMOC results each multiplied by the number of samples in the cannister, divided by the total number of acceptable samples (23). The adjusted weighted average NMOC concentration for the eight Tier 2 samples was 193 parts per million by volume (ppmv) as hexane. A copy of the laboratory analysis results, ATL's laboratory analysis, and quality control data are provided in Appendix C of this report.

Proposed Tier 2 Sample Locations l l f f I January 2006 Shaw Environrnenta[, Inc. INTRODUCTION Waste Management of Hawaii, Inc. (WMH) is requesting authorization to perform a Tier 2 study at the West Hawaii Sanitary Landfill (WHSL) in Waikoloa, Hawaii, in accordance with the New Source Performance Standards (NSPS) for Municipal Solid Waste Landfills and State of Hawaii Department of Health (DOH) requirements. The West Hawaii Sanitary Landfill is owned and operated by the County of Hawaii, and managed under contract by WMH. The facility originally prepared and submitted an NSPS Design Capacity and Tier 1 report in June 1996. The initial Tier 1 report estimated that the non-methane organic i compound (NMOC) emissions generated from the site did not exceed 50 megagrams per year (Mg/yr), thus a gas collection and control system (GCCS) was not necessary at that time. WMH is conducting this Tier 2 NMOC landfill gas (LFG) concentration analysis to determine whether a GCCS is currently required at the WHSL. This work plan includes a description of the Tier 2 sampling procedures and protocols, including minor modifications to the standard Tier 2 methodology for determining the site-specific NMOC concentrations. SITE INFORMATION The WHSL has been in operation since 1993 and its design capacity is approximately 11,744,000 cubic yards. The WHSL currently contains approximately 1.2 million tons of waste in place in 7 cells over approximately 43 acres. The WHSL accepts only non- hazardousmunicipal solid waste (MSW). The WHSL is considered a new landfill under the NSPS because it began filling operations after May 30, 1991. As such it is subject to the NSPS for MSW landfills under 40 Code of Federal Regulations (CFR) Part 60, Subpart WWW, as enforced by USEPA Region IX. I SITE SAMPLING PLAN In accordance with 40 CFR §60.754 (a)(3), the NSPS Tier 2 sampling protocol requires two samples of LFG be collected per hectare (2.47 acres) of existing landfill area that has retained waste for at least two years, not to exceed a total of 50 samples. Based on review of WMH site filling information, approximately 13.1 hectares (fill cells 1 through 6) contain emplaced refuse that is older than 2 years. Thus, a maximum of 26 sample locations are proposed for the WHSL using the standard Tier 2 sample probe method. The preliminary sample locations are indicated in the figure in Attachment 1. The standard Tier 2 sampling method requires penetration into the waste below the landfill surface and cover to obtain representative LFG samples. Samples will be obtained by driving (hydraulic drill-rig direct push) a perforated stainless steel sample probe to a minimum depth of five (5) feet below the landfill surface (at least three [3] feet into the top of the waste). The sample probe consists of 4 feet of 1.5-inch nominal January 2006 j Shaw Ehvironrwual, Inc. diameter steel drill rod with a 12-inch long, 0.75-inch diameter perforated stainless steel vapor sampling tip. Shaw will utilize the standard NSPS Tier 2 sampling Method 25C, with USEPA-approved modifications incorporating composite sampling. The technician will collect a minimum 1-liter LFG volume from each sample probe location. The Tier 2 protocol allows for the compositing of samples, provided that equivalent volumes are collected from each sample point. As such, we propose to composite samples from up to three sample points into each 6-liter Summa° canister. The Summa® canisters are also pre-filled with ' 2-liters of helium, to comply with federal Department of Transportation (DOT) hazardous ~ material shipping requirements. I~' The proposed sampling protocol at each completed probe location will be as follows: ~ The sample train will be tested for leakage by evacuating to approximately -20 inches mercury vacuum gage (in. Hg) using a hand pump. The sample train shall hold the vacuum for 3 minutes with no more than 1 in. Hg vacuum decrease. • Prior to collecting the LFG samples, a Landtec GEM-500° or GEM-2000° infrared LFG analyzer will be used to purge the sample probe and sample train, and measure ~ the initial oxygen, carbon dioxide, and methane concentrations for compliance with the NSPS concentration limits (<20 percent nitrogen by volume). • The technician will purge the sampling train of two sample probe volumes at a rate of 500 milliliters per minute (ml/min) or less. The sample probe volume is ` approximately 1.1 liter. • After confirmation of no leakage and acceptable LFG concentrations, the technician will shut-off the sample valve to the LFG analyzer and open a second valve to collect 1 liter of sample into an evacuated Summa° canister, at a rate of 500 ml/min or less. • The nine sample canisters will shipped overnight to Air Technology Laboratories (ATL) in Southern California for laboratory analysis using USEPA Method 25C for the NMOC analysis and USEPA Method 3C for the nitrogen and oxygen analysis. An additional canister will be transported as a trip blank, to confirm quality control protocols during shipping and handling. • Other major fixed gases (methane, carbon dioxide, and hydrogen) will also be quantified and reported, for evaluation of the biochemical stage of the waste degradation. • Each canister will be analyzed by the laboratory in triplicate, and the average of the three results will be reported. • The NMOC concentrations will be reported as hexane equivalent after correction to standard conditions for sampling temperature, barometric pressure, helium pre-fill and injection padding pressures, water vapor, and nitrogen content. January 2006 2 Shaw Environmental, Inc. NMOC EMISSIONS MODELING Once the LFG NMOC analytical results are received and reviewed, the site-specific NMOC concentration will be used in the USEPA Landfill Generation Model (LANDGEM) to estimate the current NMOC emission rate. The average NMOC concentration used in the model will be based on the arithmetic average of all the acceptable test samples. Results will be provided in a final report prepared by Shaw and submitted to the DOH - and USEPA for review and approval.

The software provides a relatively simple approach to estimating landfill gas emissions. Model defaults are based on empirical data from U.S. landfills. Field test data can also be used in place of model defaults when available. Further guidance on EPA test methods, Clean Air Act (CAA) regulations, and other guidance regarding landfill gas emissions and control technology requirements can be found at http://www.epa.gov/itnatw0l/landfill/landflpg.html. LandGEM is considered a screening tool -the better the input data, the better the estimates. Often, there are limitations with the available data regarding waste quantity and composition, variation in design and operating practices over time, and changes occurring over time that impact the emissions potential. Changes to landfll operation, such as operating under wet conditions through leachate recirculation or other liquid additions, will result in generating more gas at a faster rate.

(Shaw) herein provides a summary report of sampling, and analysis of fixed gas concentration for West Hawaii Sanitary Landfill (WHSL), located in Waikoloa, Hawaii. Summaries of the field sampling activities, laboratory analysis, and correction calculations are described in this report. The WHSL is owned and operated by the County of Hawaii, and managed under contract by Waste Management of Hawaii, Ina (WMH). WMH is submitting this report to the State of Hawaii Department of Health (DOH) Clean Air Branch and United States Environmental Protection Agency Region IX per their request to analyze the landfill gas (LFG) for elevated hydrogen gas concentrations.

Sampling locations were placed accordance with the NSPS Tier 2 sampling requirements which are summarized in detail in the Tier 2 NMOC Concentration Report (Mazch 2006). A total of nine composite LFG samples from 26 sample locations were collected for gas analysis. The 26 LFG samples were combined into nine SUMMA canisters per Shaw's modified USEPA Method 25C procedures as submitted to the USEPA in the January 2006 Tier 2 Work Plan. The samples were transferred to Air Technologies Laboratories, Ina (ATL, City of Industry, CA) for analysis under USEPA Methods 3C and 25C. csn~ ~ i,oaenwm naw.~nwes~ newza~zoos ~~e, zu«~4eponsrGnznwat n _nz.epo~ a-s-oe eoo~ow o ae~ o. vl sroe 119185 2-1 3 SUMMARY OF LABORATORY ANALYTICAL RESULTS All laboratory analyses were performed by ATL. Following laboratory analysis, gas concentrations were calculated from raw laboratory analytical data in accordance with USEPA Methods 25C and 3C. Laboratory calculations included method corrections for sampling temperature, final canister pressure, moisture and nitrogen content. A summary of laboratory analytical results is shown in Table 1. Hydrogen was not detected in any of the nine composite samples above the method reporting limit of 4.7 percent by volume. The practical hydrogen quantitation limit for USEPA Method 3 (without sample dilution) was I.0 percent by volume.
