MARIPOSA BIOMASS PROJECT AIR QUALITY and GREENHOUSE GAS EMISSIONS

Introduction

The potential air emissions of the proposed 2.4-MW net (2.7 MW gross) woody biomass gasification to electricity facility are presented and discussed below for the purposes of supplying the Mariposa County Planning Department and the Mariposa County Air Pollution Control District with background information and data for their respective CEQA review of the Mariposa Biomass Project.

TSS Consultants (TSS) of Sacramento, CA was retained by the Mariposa County Resource Conservation District to prepare the following analyses.

Air Quality

Projected Emissions – Stationary Sources

The proposed bioenergy facility will utilize approximately 12,000 bone dry tons (BDT) of woody biomass waste per year. Total electrical production will be 2.7 MW gross, with 2.4 MW net transmitted to the grid. As the proposed project will sell electrical power to Pacific Gas & Electric under the California Bioenergy Market Adjustment Tariff (BioMAT) Category 3, 80% of the woody biomass waste will originate from forest sources, much of which would have been otherwise piled and burned.

The facility is planned to operate 24/7, however given there will be scheduled and unscheduled maintenance requirements for the equipment it is anticipated that the bioenergy facility will likely only operate approximately 330 days per year.

The proposed facility will utilize the Cortus Energy WoodRoll woody biomass gasification to electricity technology (see Figure 1 below) The facility includes a fuel drier, which removes moisture from the fuel before it enters the pyrolizer. Char produced by the pyrolizer is indirectly heated using the gases generated in the pyrolysis process and mixed with steam to produce a low nitrogen syngas. The syngas is to be combusted in two GE Jenbacher, type 6 gas engine generators to produce electricity (see Appendix A for engine specifications). The engines are equipped with SCRs for NOx control and CO catalysts for increased CO emission reduction. Particulate Matter will be controlled by filters (syngas filter and pyrolysis gas exhaust filter). The exhaust gas from the two engines as well as the exhaust from the fuel drier is ducted to one common stack. The facility also includes a flare to burn excess fuel during startup, shutdown and emergency upset conditions.

CalEEMod Modeling for Project Emissions

Emissions modeling for this project was performed using California Emission Estimator Model (CalEEMod) Version 2016.3.1. Project specific data was applied when available and remaining data was populated with Mariposa County APCD default data. Construction is not expected to occur during every day during the construction schedule, therefore, two model runs were performed, one with the actual as expected construction schedule for the worst-case daily emissions and one model containing a condensed single year construction schedule to represent the worst-case annual emissions. A condensed construction schedule was used to more accurately calculate annual emissions by basing the construction schedule on the number of working days. For example, if a construction phase was expected to range three months and only have 20 days of construction activity, it would be modeled in the condensed schedule version as a single month to account for a total of 20 working days instead of the CalEEMod auto calculated 60 days.

Project Emissions - Construction

The construction of the bioenergy facility will include the erection of an enclosed warehouse-type building, road construction, and site grading. There is expected to be no demolition of buildings or related structures as none currently exist onsite.

Project construction is assumed by the developer to take 9 months with approximately 2.4 acres of disturbed ground area. Grading/site preparation will utilize 1 each heavy wheel loader, hydraulic excavator, grader, material handling crane, and dump truck. Table 2 presents the maximum daily and annual construction emissions.

Project Emissions – Mobile and Temporary Sources

Mobile emission sources for the proposed bioenergy facility operation include truck activity (for chip delivery), loader activity (to move onsite biomass), employee commute trips, biomass hauling, and ash hauling. The front loader will operate onsite moving biomass from the storage windrows to the dryer’s feedstock hopper and stacking the storage windrows during and after feedstock delivery. Truck activity will follow the all- weather access roads onsite to reach the storage windrows. The scale is onsite and immediately adjacent to the bioenergy facility.

The following CalEEMod inputs were used to estimate the operational mobile source emissions. • 10 full-time employees with 10 round trips for a per day commute at an average 60 miles round trip; • 12 additional jobs for recovering biomass with 12 round trips per day at an average 60 miles round trip

TSS Consultants 4 November 2017

• Woody biomass fuel vehicles (i.e. chip vans) with a haul capacity of 12.5 BDT per load with 960 loads annually for 12,000 BDT of delivered biomass. Assume average 60 mile round-trip for feedstock acquisition: • Ash removal, 650 tons per year (one 12.5 ton truckload per week), assume 2 mile round trip to nearby Mariposa County Landfill and Recycling Center.

The result of the operational mobile and temporary source emissions are presented in Table 3.

These results of the CalEEMod modeling are found in Appendix B. Daily emissions from Section 4.1 of Daily Emissions Modeling Spreadsheet and Annual emissions from Section 4.1 of Annual Emissions Modeling Spreadsheet.

MCAPCD Significance Thresholds and Potential to Emit

The MCAPCD has not formally adopted thresholds of significant impact for the purposes of CEQA review. Thresholds of potential significant impact were nonetheless identified in the 2006 Final Environmental Impact Report prepared for the Mariposa County General Plan. In Table 4.8-1 of the Final EIR1, the emissions in excess of 100 TPY of any criteria air contaminant would be the threshold for significant impact. In addition, the values listed in Table 4 were further confirmed by the MCAPCD2.

Pre-Project Potential to Emit

The potential to emit before the implementation of the proposed project is from the disposal method of the sustainably sourced forest woody biomass feedstock. Emissions factors for biomass feedstock fated to the pile and burn scenario are based on a study by the National Renewable Energy Laboratory (NREL)3. These emission factors are verified in a technical paper by the Placer County Air Pollution Control District in 20114. The results of these studies are shown in Table 5 include the emissions from processing and transportation of the woody biomass feedstock

Table 5. Pile and Burn Emission Factors Pollutant EF (lb/thousand BDT) VOC 24,000 NOx 2,500 CO 150,000 SOx 150 PM10 15,000

Net Potential to Emit

The factors in Table 5 are then utilized in Table 6 (along with results in Tables 1 and 3) below to determine the emissions from the standard practice of pile and burn of the woody biomass waste in the forest, which release uncontrolled emissions. The amount of forest-sourced woody biomass to be used (no less than 80% of the annual 12,000 BDT as required by BioMAT) and assuming 60% of that material would have been piled and burned is then calculated and compared to the operational and construction emissions in Tables 1, 2, and 3. The difference between the pile and burn and the operational/construction emissions can then be compared to the MCAPCD thresholds of significance (Table 4).

The net emissions based on the project represent the difference between the pre- project potential to emit and the project’s potential to emit, as shown in Table 6.

TSS Consultants 7 November 2017 As can be seen in Table 6 above, the differentials between pile and burn emissions and the emissions from operations and construction are considerable, and place all the net emissions significantly below the MCAPCD significance thresholds.

It should be noted that this net emissions analysis does not exempt the facility from acquiring an Authority to Construct permit in which the diversion of the emissions from pile and burn will not be considered.

Calculation of the Pile and Burn Diversion Rate

In August 2015 TSS completed a biomass feedstock availability analysis for the Mariposa Biomass project, on behalf of the Mariposa County Fire Safe Council5. Analysis and information in that analysis served as a basis for the diversion rate determination

Optimized Feedstock Blend

The August 2015 feedstock supply availability analysis report included an optimized feedstock blend forecast: Table 7: Optimized Feedstock Blend

Volume Percent Of Source (BDT/Yr) Total Forest 12,800 80% Urban 2,400 15% Agriculture 800 5% TOTALS 16,000 100%

Feedstock Procurement Forecast

It is TSS understanding that the Mariposa Biomass facility is expected to enter commercial service Q2 2020. Table 8 is a fuel procurement forecast by fuel type for the facility’s initial year of commercial operation (Q2 2020 to Q2 2021). Table 8:Year One Feedstock Procurement Forecast Volume Fuel Type (BDT/Yr) Usual Fate Timber Harvest Residuals 6,800 Open Burn 40% Open Burn/60% Hazardous Fuels Removal 6,400 chip/scatter Total Forest 13,200

TSS conducted interviews with foresters that are familiar with forest practices in the Mariposa/Madera County region in order to generate this feedstock forecast. Information provided by these local foresters included:

• Historic timber harvest residual disposal methods. • Current fuels treatment methodologies and disposal options. • Planned tree mortality mitigation plans.

In addition, TSS utilized past experience as a forester6 and fuel procurement manager, and knowledge of current forest and agricultural management practices to generate this forecast.

To increase the conservative nature of the emissions analysis, a diversion rate of 60% was used in Table 6

Health Risk Assessment Dispersion Model Selection The health risk assessment (HRA) modeling for the project operations was conducted using the California Air Resources Board (ARB) Hotspots Analysis Reporting Program Version 2 (HARP 2) and the state-approved air dispersion modeling program AERMOD based on guidance and data from the California Office of Environmental Health Hazard Assessment (OEHHA) guidelines (OEHHA, 2015). The technical options selected for dispersion modeling include: • Regulatory default control options • Rural dispersion mode • Receptor elevations and controlling hill heights obtained from AERMAP (version 11103 or most recent) output

Source Characterization

The facility sources including two syngas-fueled internal combustion engines and the Wood Roll process are vented through a single common facility stack and were therefore modeled as a single point source. Emissions for each source were combined with the exhaust parameters obtained from manufacturer data. A table of the facility stack parameters is presented in Table 9 below and emissions are presented in Appendix C.

Table 9. Modeling Parameters Stack Height (m) 18.29 Stack Diameter (m)* 1.0 Exhaust Gas Flow Rate (m3/hr)** 17,145.4 Exhaust Velocity (m/sec) 6.06 Exhaust Temperature (deg. C)*** 220 * Stack diameter represents the inner diameter of the facility stack. ** Exhaust gas flow rate represents the manufacturer supplied flow rate multiplied by two to account for both engines exhausting through a common stack. ***Exhaust temperature accounts for heat recovery processes from exhaust stream resulting in a lower exhaust temperature.

Meteorological Data

Preprocessed meteorological data for input into AERMOD was obtained from the San Joaquin Valley Air Pollution Control District website for the Madera station (Station ID: 93242) located approximately 36 miles south of the site. This meteorological data site was selected as representative due to the following reasons: proximity to the proposed project, similar local land cover area to the proposed project area, and minimal terrain between the proposed project and selected meteorological station.

Receptor Selection

The receptor grid modeled in this risk analysis includes fence line receptors, sensitive receptors, census centroid receptors, and gridded receptors. The receptors were spaced to provide sufficient estimation of the maximum concentrations and elevations were based on the AERMAP model run output. The receptor spacing is as follows:

• 50-meter spacing along the fence line • 50-meter spacing from the fence line to 1,000 meters beyond the fence line • 200-meter spacing from 1,000 meters to 5,000 meters beyond the fence line TSS Consultants 10 November 2017

In total, cancer and non-cancer risks were evaluated at 5,402 receptors. The receptor breakdown is as follows:

• Receptors 1 through 5,337: Gridded Receptors • Receptors 5,338 through 5,400: Census Receptors • Receptors 5,401 through 5,402: Sensitive Receptors

Figure 2 shows the receptor grid showing the receptor grid spacing overlaid on an aerial map. Census receptors within the modeling domain were extracted directly from HARP2 and are based on 2010 census data. Sensitive receptors include schools (kindergarten through 12th grade), day care centers, nursing homes, retirement homes, health clinics, and hospitals.

Health Risk Modeling Carcinogenic

The point of maximum impact (PMI), maximally exposed individual residence (MEIR) excess cancer risks were evaluated using the 30-year exposure duration scenario. The maximally exposed individual worker (MEIW) cancer risk was evaluated using the 25-year exposure duration as recommended in the OEHHA Guidelines7. Based on the Risk Management Guidance for Stationary Sources of Air Toxics8, the Derived (Adjusted) Method in HARP 2 was used for the excess cancer risk assessment, which uses the 95th percentile breathing rate from the 3rd trimester to 2 years and the 80th percentile inhalation rate from 2 years to 70 years for MEIR excess cancer risk assessments. The 30-year and 25-year exposure durations for the MEIR and MEIW were obtained from the OEHHA Guidelines.

Excess cancer risks were evaluated based on the annual toxic emissions impacts at ground level, inhalation cancer potency, oral slope factor, frequency and duration of exposure at the receptor, and breathing rate of the exposed persons. The MEIW incremental cancer risk was conservatively assumed to occur at the maximum impacts receptor in the modeling domain to account for new industrial activities potential to occur anywhere within the modeling area.

Non-Carcinogenic

The PMI, MEIR, MEIW and maximum sensitive receptor non-carcinogenic acute and chronic health effects were evaluated using the default OEHHA input assumptions. The health index is obtained by dividing the calculated increase acute and chronic risk by the acute and chronic RELs. Chronic toxicity is defined as adverse health effects from prolonged chemical exposure, caused by chemicals accumulating in the body. Acute toxicity is defined as adverse health effects caused by a brief chemical exposure of no more than 24 hours. To assess chronic and acute non-cancer exposures, annual and 1-hour toxic air contaminant ground-level impacts are compared with the reference exposure levels (REL) developed by OEHHA to assess the chronic or acute hazard index.

HARP Options

The most recent version of HARP 2 (Version 17052), with the revised unit risk and cancer potency values, version 17228, was used for this analysis. The updated sensitivity factors were applied in accordance with the current regulatory guidance (ARB, 2015).

The deposition rate modeled in HARP 2 was set to 0.02 meters per second because the facility sources are considered controlled. In addition to inhalation exposure, the HRA assesses potential health impacts related to exposure from farm produce, mother’s milk, dermal absorption (mixed climate), and soil ingestion as required by OEHHA guidelines.

Exposure Pathways

For this analysis, the following applicable exposure pathways in Table 10 were included for each risk scenario: Table 10. Exposure Pathways Risk Analysis Modeled Exposure Intake Rate Percentile Pathways Acute/8-Hour Inhalation OEHHA Derived Method Inhalation Soil Ingestion Non-Cancer Chronic Dermal Absorption OEHHA Derived Method Mother's Milk Farm Produce Inhalation Soil Ingestion RMP using the Derived Cancer Dermal Absorption Methodology Mother's Milk Farm Produce

The OEHHA Derived Method for non-cancer chronic assessments uses the 95th percentile (High End) values for calculation for the inhalation pathway and the next two risk driving pathways while the remaining exposure pathways will use the 65th percentile values (Mean). The RMP using the Derived Methodology uses the 95th percentile values for all inhalation risk calculations.

Health Risk Assessment Results

Table 11 presents the results of the HRA based on the modeling and risk assessment methodology presented above. As noted above, the MEIW results are based on the impact results at the PMI, assuming workers are exposed only during work hours. This is the reason for the difference between the PMI and MEIW excess cancer risks. Figure 3 shows the location of the excess cancer risk and acute and chronic hazard index for the PMI, MEIR, and MEIW. TSS Consultants 14 November 2017

The exhaust stack height was developed to balance aviation safety concerns with air quality/public health impacts. Reducing the exhaust stack height from the proposed 60 feet would result in higher air dispersion modeled ground-level impacts due to a lower release height. In addition, lowering the exhaust stack height could result in building-induced downwash of the exhaust plume, which is caused by building or structures wake effect resulting in a downward trajectory winds in the project area. This downward wind trajectory causes the exhaust plume to also be directed downward, resulting in less plume dispersion and higher modeled ground-level concentrations.

Long Term and Cumulative Impacts

With the project emissions below the MCAPCD thresholds of significant impacts, potential long-term impacts are also insignificant.

Regarding potential cumulative air quality impacts, one of the principal air quality impacts in the region is the pile and burning of woody biomass waste from forest management operations. Per the calculations in Table 6, the proposed bioenergy project actually reduces cumulative impacts

Odors

The proposed project is not considered a major source of odor emissions. The project could introduce new odor sources in the project area such as from anaerobic activity in the storage piles of biomass feedstock, and additional diesel

TSS Consultants 16 November 2017

vehicle emissions. However, such odor sources at the site are not expected to impact adjacent land uses, as project operations would include measures to avoid anaerobic activity in the storage piles. Plus, the nearest sensitive receptors (residences) are over 1,000 feet to the northeast.

TSS Consultants 17 November 2017

Greenhouse Gas Emissions

CalEEMod was also used to assess the project construction greenhouse gas (GHG) emissions. Table 12 presents the results of the construction GHG assessment. The CalEEMod results are found in Appendix B. Table 12. Construction GHG Maximum Controlled Annual Pollutant Emissions (metric tons) Carbon Dioxide-Equivalent 360.54

CalEEMod was also used to assess the project operational mobile and temporary source greenhouse gas (GHG) emissions. Table 13 presents the results of the operational mobile GHG assessment. Table 13. Mobile GHG Emissions Maximum Controlled Annual Pollutant Emissions (metric tons) Carbon Dioxide-Equivalent 1,054.57

Using the above CalEEMOD data and calculated GHG emissions from the combustion of 12,000 BDT annually by the proposed facility and from the 60% reduction of open burning of the woody biomass waste, the following Table 14 results in the total GHG burden of the bioenergy facility. Table 14.

Regarding the total GHG emissions whether it be the total gross GHG emissions (21,826.57 MT/year) or the net GHG emissions after considering the offset of GHG from reduced open pile burning (9,370.57 MT/year), it should be noted that

the MCAPCD does not have a GHG emissions significant impact threshold value. The California Air Resources Board (CARB) has used 25,000 metric tons/year as a reporting threshold for the cap and trade program, but was not specifically established as a CEQA threshold for GHGs. However, in the report titled: CEQA and Climate Change: Evaluating and Addressing Greenhouse Gas Emissions from Projects Subject to the California Environmental Quality Act12, the California Air Pollution Control Officers Association (CAPCOA) identifies the 25,000 metric ton threshold, as used by CARB for their reporting threshold, as a potential and appropriate non-zero GHG threshold for use in a CEQA document (see pages 44-45 of the above-referenced 2008 report13).

Additionally, the U.S. EPA regulations for reporting of GHG emissions set a 25,000 metric ton threshold for large emission sources and the European Union has provided for “small installations” with emissions under 25,000 metric tons to be exempted from its Emissions Trading Scheme; notably, biomass emissions are excluded from this calculation.

In summary, a 25,000 metric ton threshold has been determined in several state, federal, and international rulemaking processes to represent a significant level of emissions with respect to cumulative contributions to global climate change. Given the research and resources that went into the development of the GHG Mandatory Reporting Rule and cap and trade programs adopted by CARB, the U.S. EPA GHG reporting rule, and the fact that the 25,000 metric ton threshold would capture approximately 94 percent of GHG emissions associated with stationary sources in California (CAPCOA, page 44), this level could be used as the significant impact threshold for GHGs in the MCAPCD

Therefore, if the proposed project generates 25,000 metric tons of CO2e or greater in a year, it would be considered to have a significant and cumulatively considerable impact on the environment. If the proposed project would generate

less than 25,000 metric tons of CO2e per year, it would be considered a less than significant and less than cumulatively considerable impact related to climate change and GHGs. In order to determine if the proposed project would conflict with an applicable plan, policy, or regulation adopted for the purpose of reducing the emissions of GHGs, the proposed project is compared to the most applicable and relevant state-level regulations adopted to reduce GHG levels.

It must be noted that Table 14 calculates the GHG emissions without considering the carbon neutrality of woody biomass. Woody biomass combustion for the production of electricity is considered to be carbon neutral by state, federal and international agencies. CO2e emissions related to the burning of woody biomass has been exempted from the California Cap and Trade program for this reason and, as such, it is reasonable to consider the calculation of total emissions as

12 http://www.capcoa.org/wp-content/uploads/2012/03/CAPCOA-White-Paper.pdf 13 Ibid

TSS Consultants 19 November 2017

potentially carbon neutral when determining the project’s environmental impacts. If the project emissions in Table 9, i.e., the GHG emissions from the combustion of woody biomass, is considered zero, then the GHG burden of the proposed project is 1,067 MT/year.

0.10 Technical parameters

The following “Technical Instruction (TI) of GE JENBACHER” form an integral part of the contract and must be strictly observed:

TI 1100-0110 – Boundary Conditions for GE Jenbacher Gas Engines TI 1100-0111 – General Conditions – Operation and Maintenance TI 1100-0112 – Installation of GE Jenbacher Units

These Technical Instructions reference other guides and instructions which can be provided upon request. These instructions should be carefully reviewed by all personnel involved with the application, installation design, installation construction, and overall maintenance of any GE Jenbacher gas engine.

All data in the technical specification are based on engine full load (unless stated otherwise) at specified temperatures as well as the methane number and subject to technical development and modifications. For isolated operations, an output reduction may be applicable per the block load diagram. Before being able to provide exact output numbers, a detailed site load profile needs to be provided (motor starting curves, etc.).

All pressure indications are to be measured and read with pressure gauges (gauge).

(1) At nominal speed and standard reference conditions ICFN per DIN-ISO 3046 and DIN 6271, respectively (2) As detailed in DIN-ISO 3046 and DIN 6271, respectively, with a tolerance of + 5 %. Efficiency performance is based on a new unit (immediately upon commissioning). The effects of degradation during normal operation can be mitigated through regular service and maintenance work. (3) Average value between oil change intervals as per the maintenance schedule, without oil change amount (4) At p. f. = 1.0 as detailed in VDE 0530 REM / IEC 34.1 with relative tolerances, all direct driven pumps are included (5) Total output with a tolerance of +/- 8 % (6) As detailed in above parameters (1) through (5) (7) Only valid for engine and generator; module and peripheral equipment not considered (at p. f. = 0.8), (guiding value) (8) Exhaust temperature with a tolerance of +/- 8 % (9) Intercooler heat on: * standard conditions (Vxx) - If the turbocharger design is done for air intake temperature > 30°C (86°F) w/o de-rating, the intercooler heat of the 1st stage need to be increased by 2%/K starting from 25°C (77°F). Deviations between 25 – 30°C (77 – 86°F) will be covered with the standard tolerance. * Hot Country application (Vxxx) - If the turbocharger design is done for air intake temperature > 40°C (104°F) w/o de-rating, the intercooler heat of the 1st stage need to be increased by 2%/K starting from 35°C (95°F). Deviations between 35 – 40°C (95 – 104°F) will be covered with the standard tolerance.

Definition of output  ISO-ICFN continuous rated power: The Net Break Power that the engine manufacturer declares an engine is capable of delivering continuously, at stated speed, between the normal maintenance intervals and overhauls as required by the manufacturer. Power determined under the operating conditions of the manufacturer’s test bench and adjusted to the standard reference conditions.   Standard reference conditions: Barometric pressure: 1000 mbar (14.5 psig) or 100m (328ft) above sea level Air temperature: 25°C (77°F) or 298 K Relative humidity: 30 %

 Volume values at standard conditions (fuel gas, combustion air, exhaust gas) Pressure: 1013.25 mbar (14.7 psig) Temperature: 0°C (32°F) or 273 K

Output adjustment for turbo charged engines The ratings in this specification are valid for an installation at an altitude 0ft (0m) and an air intake temperature T1 < 95F (35C). At T1 > 95F (35C), an output derating of 1.11%/F (2.0%/C) will occur.

Radio interference level The ignition system of the gas engines complies the radio interference levels of CISPR 12 and EN 55011 class B, (30-75 MHz, 75-400 MHz, 400-1000 MHz) and (30-230 MHz, 230-1000 MHz), respectively.

Parameters for the operation of GE Jenbacher gas engines

Maximum room temperature: 50°C (122°F) (T2) -> engine stop

If the actual methane number is lower than the specified, the knock control responds. First the ignition timing is changed at full rated power. Secondly the rated power is reduced. These functions are carried out by the engine management.

Operation of Voltage and frequency outside of stated limits for the generator as per IEC 60034-1 Zone A will result in a power de-rate up to and including tripping of the equipment.

The generator set fulfills ISO 8528-9 limits for mechanical vibrations.

If possible, railway trucks must not be used for transport (TI 1000-0046).

Parameters for the operation of control unit and the electrical equipment  Relative humidity: 50%  Maximum temperature: 40°C (104°F).  Altitude: < 6560ft (2000m) above the sea level.

The gas quantity indicated under technical data refers to standard conditions with the given calorific value. Actual volume flow (under operating conditions) must be considered for dimensioning of any the gas compressor and associated fuel system component. These elements will also be affected by:  Actual gas temperature (reference TI 1000-0300 for temperature limits)  Gas humidity (reference TI 1000-0300 for temperature limits)  Gas Pressure (page 5 of this specification)

0.11 Additional Technical parameters

 Idle load operation (without grid) with wood gas is not allowed.

 The engine room ventilation must be designed as a forced system (with intake fans), so that there is always a slight overpressure in the engine room. This ensures that any unburned exhaust gas will be forced out of the exhaust system and cannot leak back into the engine room.

 The engine room ventilation must be designed so that in case of leaks no ignitable amounts of gas can form.

 It must be insured that during any operational mode no ignitable gas mixture is evident at any of GE Jenbacher delivered components. See TA 1000-0110.  A emergency cut off valve that can be controlled by Jenbacher shall be installed outside of the engine room.

 The gas warning system must be designed according to the gas composition

 All persons in the immediate vicinity of the site must be equipped with a suitable wearable gas warning sensor. Relevant warning and security notification boards for CO, H2 and other poisonous and flammable gases/substances must be visible positioned and in a manner that informs and motivates personal correctly.

 The gas, according to TA 1000-0300 and at the given parameters (gas temperature < 50°C, gas pressure 105-200mbar) must be free of condensate and/or sublimates.

1.00 Scope of supply - Module

Design: The module is built as a compact package. The engine base is bolted to the gearbox/generator base. The Engine output shafting is connected through a coupling to a gearbox. A second coupling is then provided connecting the gearbox to the generator. To provide the best possible isolation from the transmission of vibrations, the engine rests on the engine base-frame by means of anti-vibration mounts. The remaining vibrations are eliminated by mounting the complete module (engine and gearbox/generator frames) on isolating pads (e.g. Sylomer). This, in principle, allows for placing of the module to be directly on any floor capable of carrying the static load. No special foundation is required. Prevention of sound conducted through solids has to be provided locally.
