2.0 SITE PROCESS INFORMATION

2.1 PROCESS DESCRIPTION

The Patton Trust South Production Facility receives a three-phase stream from onsite (within 0.25 mile) and offsite production wells via pipeline to separators. Liquids from the separators are sent to heater treaters (FIN: HTR-01 through HTR-04, HTR-06 through HTR-08) which heat the stream enabling further separation of gas from the oil/condensate and produced water. The produced water from the inlet separators and the heater treaters is routed to a heater treater (FIN: HTR-05) for further separation of oil/condensate and then to the produced water storage tanks (FIN: PWTK-01 to PWTK-05). The oil/condensate from the heater treaters is routed to the VRTs for further stabilization and then to the oil/condensate storage tanks (FIN: OILTK-01 to OILTK-22). The tanks (FIN: OILTK-01 through OILTK-23; PWTK-01 through PWTK-05) are controlled by a vapor recovery unit (“VRU”), driven by a natural gas engine (FIN: ENGVRU-04). A small amount of liquids off the compressors and various process equipment are routed to the drip VRT for stabilization and then to the oil/condensate storage tanks (FIN: OILTK-21, OILTK-22). The oil/condensate from the oil/condensate storage tanks (FIN: OILTK-01 through OILTK-22) passes through the LACT units to another oil/condensate tank (FIN: OILTK-23) and is then removed from the tanks by pipeline or loaded into trucks (FIN: LOAD) for up to 2,500 loadouts per year. Produced water is loaded into trucks (FIN: LOAD) for transport offsite. Flashed gas off the VRTs (FIN: VRT-GAS, DRIPVRT-GAS) is hard-piped to and compressed by VRU compressors, driven by natural gas-powered engines (FIN: ENGVRU-01 through ENGVRU-03). Flashed gas off the VRTs (FIN: VRT-GAS, DRIPVRT-GAS) may also be routed to the process flare (FIN/EPN: FLR-02). Flashed gas off of the heater treaters and the low pressure drip scrubber (FIN: PROD-GAS), and the VRU compressors is compressed by the flash gas compressors, driven by natural gas-powered engines (FIN: ENG-04 through ENG-06). Flashed gas off of the heater treaters and the low pressure drip scrubber (FIN: PROD-GAS) may also be routed to the utility flare (FIN/EPN: FLR-01). Gas off the inlet separators (FIN: PROD-GAS) is either sent directly to the utility flare (FIN/EPN: FLR-01), gas sweetening unit, or compressed by the IP compressors, driven by natural gas-powered engines (FIN: ENG-01 through ENG-03). Gas from the IP and flash compressors is routed to coolers, driven by natural gas-powered engines (FIN: ENG-07, ENG-08). The liquids off the cooler scrubber that are routed through a line heater (FIN: HTR-10) and then to a low pressure drip scrubber, will be sent offsite via pipeline to the Patton Trust North Production Facility. Following the cooler scrubber, the produced gas is treated in a gas sweetening unit (a closed system with no associated emissions) and a glycol unit (FIN: DEHY-01, HTR-09). A fraction of the sweetened gas is routed to a fuel conditioning skid (no associated emissions) and used on site for fuel. The remaining gas is sent to the sales pipeline or used for gas lift.

Other sources of emissions include piping fugitive emissions (FIN: FUG), catalytic heaters (FIN: CAT-HTR) used in various operations at the site, and emissions from planned MSS activities, which are detailed in Section 2.3. See Appendix D for a simplified process flow diagram.

2.2 EMISSION CONTROLS

Vapors from the oil/condensate and produced water storage tanks (FIN: OILTK-01 through OILTK-23, PWTK-01 through PWTK-05) are routed to the process flare (FIN/EPN: FLR-02) for 99% (C3) / 98% (C4+) control of VOC and 98% control of H2S. Vapors from the storage tanks (FIN: PWTK-01 to PWTK-05, OILTK-01 through OILTK-23) are routed to a VRU compressor, driven by a natural gas-powered engine (FIN: ENGVRU-04) for 98% capture/control efficiency with the vent gas being routed back to the process flare (FIN/EPN: FLR-02) for 99% (C3) / 98% (C4+) control of VOC and 98% control of H2S. The VRU at the Patton Trust South Production Facility is a natural gas engine-driven mechanical VRU (mVRU) and operates in conjunction with an electric blower system. Encana maintains records of the following design requirements for claiming 98% control (Table 8 of 30 TAC §116.602 NON RULE 2012-NOV-08):

The VRUs use a pressure sensing device that provides constant pressure readings to maintain a pressure inside the storage tanks below the thief hatches opening pressure.

Properly designed bypass system: when the VRUs are taken offline for repairs or maintenance, the electric blowers routed vapors to the process flare for control.

Adequate compressor selection: an estimated gas production and number of flash vessels were provided to the VRU vendor to determine adequately sized compressors for use at the site.

Oil/condensate and produced water loading vapors (FIN: LOAD) are routed to the process flare (FIN/EPN: FLR-02) for 99% (C3) / 98% (C4+) control of VOC and 98% control of H2S. The tank trucks are not leak tested based on EPA standards (NSPS XX); therefore, a vapor capture/collection efficiency of 70% was used in the emission calculations. Flashed gas off the VRTs (FIN: VRT-GAS, DRIPVRT-GAS) may be routed to the process flare (FIN/EPN: FLR-02) for 99% (C3) / 98% (C4+) control of VOC and 98% control of H2S. Produced gas (FIN: PROD-GAS) may be routed to the utility flare (FIN/EPN: FLR-01) for 99% (C3) / 98% (C4+) control of VOC and 98% control of H2S. Flash tank vapors from the glycol unit flash tank (FIN: DEHY-01) are premixed with the primary fuel gas and controlled by the unit reboiler for 99% control of VOC and H2S (EPN: DEHY-01) or are routed to the process flare (FIN/EPN: FLR-02) for 99% (C3) / 98% (C4+) control of VOC and 98% control of H2S. Emissions from the glycol unit flash tank are conservatively calculated

assuming that flash tank vapors are routed to the control device with the lowest destruction efficiency (process flare) for the entire year. Condenser vapors from the glycol unit condenser (FIN: DEHY-01) are premixed with the primary fuel gas and controlled by the unit reboiler for 99% control of VOC and H2S (EPN: DEHY-01) or are routed to the unit glow plug for 98% control of VOC and H2S. Emissions from the glycol condenser are conservatively calculated assuming that condenser vapors are routed to the control device with the lowest destruction efficiency (glow plug) for the entire year. Leak Detection and Repair Program (LDAR): Emissions from fugitive components in gas and liquid service have the uncontrolled potential to emit greater than 25 tpy VOC and are, therefore, subject to a LDAR program as specified in Table 9 in paragraph (m) of the non-rule standard permit. Encana has implemented the applicable LDAR Program from Table 9 of this standard permit. Emission control efficiencies associated with this LDAR program have been applied to the fugitive emissions (FIN: FUG) included in this submittal.

2.3 PLANNED MAINTENANCE, STARTUP, AND SHUTDOWN ACTIVITIES

This permit registration includes estimated emission rates from additional planned MSS activities at this site. Annual frequencies of planned MSS activities represented in this submittal are intended to be potential-to-emit/worst case scenarios. The actual annual frequency of each activity necessary to maintain good working order of facilities/equipment may vary. Emission calculations from the following planned MSS activities are included in this submittal:

Degassing and cleaning the heater/boiler (FIN/EPN: MSS-HTRDEG, MSS-HTRCLN) Pig launcher degassing (FIN/EPN: MSS-PIG) Cleaning oil/condensate and produced water storage tanks (FIN/EPN: MSS-TNKCLN) Compressors Blowdowns/Startups (FIN/EPN: COMP-MSS/FLR-01)

2.4 ALTERNATE OPERATING SCENARIOS (AOS) ASSOCIATED WITH PLANNED

MSS ACTIVITIES

During IP compressor engine (FIN: ENG-01 through ENG-03) downtime for routine maintenance, produced gas that cannot be compressed is routed to the utility flare for control (FIN/EPN: PROD-GAS/FLR-01). During flash gas compressor engine (FIN: ENG-04 through ENG-06) downtime for routine maintenance, produced gas is routed to the utility flare for control (FIN/EPN: PROD-GAS/FLR-01) and flash gas off the VRTs is routed to the process flare for control (FIN/EPN: VRT-GAS, DRIPVRT-GAS/FLR-02). During VRU compressor engine (FIN: ENGVRU-01 through ENGVRU-04) downtime for routine maintenance, flash gas off the VRTs and the storage tanks is routed to the process flare for control (FIN/EPN: VRT-GAS, DRIPVRT-GAS, PWTK-01 to PWTK-05, OILTK-21, OILTK-22/FLR-02).

3.3 MODELED ANALYSES

The process model ProMax v3.2 was used to model the compositions listed in the below table for use in the emission calculations. ProMax models were created for each mode of operations: current and future operations. The models were only used to obtain stream compositions and gas-to-oil ratios (“GOR”) of streams shown in the table below but not to evaluate mass emissions. The calculation method for each source is detailed in Section 3.1. The models reports are in Appendix E.

4.0 IMPACTS EVALUATION

In accordance with paragraph (b)(8) of 30 TAC §116.602 – NON RULE 2012-NOV-08, an impacts analysis as specified in paragraph (k) has been conducted to demonstrate compliance with applicable National Ambient Air Quality Standards (“NAAQS”), State Property Line Standard, and Effects Screening Levels (“ESL”). The tables in Appendix B demonstrate compliance with the relevant NAAQS, State Property Standard, and ESL.

4.1 GENERIC MODELING TABLES

Impacts evaluations for SO2, benzene and H2S were conducted using the Generic Modeling Results tables in paragraph (m) of 30 TAC §116.602 – NON RULE 2012-NOV-08 to show that protectiveness limits have been met at the nearest property line.

4.2 DISPERSION MODELING

Dispersion modeling (SCREEN3) of NO2 emissions from all applicable sources was performed to ensure compliance with the hourly NAAQS for NO2. The maximum predicted impacts are shown at distances beyond the property line.

4.3 ALTERNATE NO2 BACKGROUND CONCENTRATION JUSTIFICATION

There is no NO2 monitor located in Karnes County or near the Patton Trust South Production Facility. Therefore, out of county monitors were reviewed for representativeness. The monitored concentration from the Corsicana Airport monitor was determined to be a conservative estimate of monitored emissions surrounding the Patton Trust South Production Facility. The Corsicana Airport monitor is located in Navarro County. A comparison of county-wide emissions was conducted using the 2011 National Emissions Inventory data from the EPA website. The emissions from Navarro County are approximately two (2) times the emissions from Karnes County.

Federal Applicability

40 CFR Part 63 - Subpart HH

Is this subpart applicable?

If yes, how will compliance be achieved? If no, please explain why.

Affected source is exempt from control requirements per 40 CFR 63.764 (e)(1)(ii); benzene emissions are less thank 0.90 Mg/yr (1.0 tpy).

Maintenance of records to support determination of exemption are required under §63.774(d)(1)(ii).

Enter any notes here:

All area sources, with TEG dehydration units, will have some requirements under this rule. Emission reduction requirements may apply or only recordkeeping requirements may apply.

Yes

Throughput is 3 MMscf/day or greater AND Uncontrolled Benzene emissions are 1.0 tpy or greater. Emissions reduction requirements of HH apply, but this does not necessarily mean control.

Controlled emissions are emissions after any applied controls. If emissions are totally uncontrolled, then controlled emissions will be equal to uncontrolled emissions

Emissions Calculation Methods:

[1] • Hourly Stream Flow (lb/hr) = (lb/lb-mol) * (P) * (scf/hr) * / (R) * (T)

• Hourly Flow Rate (using GOR) (scf/hr) = GOR * Max throughput (bbl/hr)

• Annual Stream Flow (tpy) = (lb/lb-mol) * (P) * (scf/yr) * / (R) * (T) * 2000

• Annual Flow Rate (using GOR) (scf/yr) = GOR * Annual hourly throughput (bbl/hr) * Hrs/yr

[2] • Hourly Flow Rate (scf/hr) = Total lb/hr * T * R / P * Stream MW

• Annual Flow Rate (scf/yr) = Total tpy * T * R / P * Stream MW

• NOx/CO (lb/hr) = (scf/hr)*EF (lb/MMBtu) * HV (Btu/scf) / 10^6

• SO2 (lb/hr) = (H2S lb/hr)*(64 lb SO2/lb-mol)/(34.08 lb H2S/lb-mol)

Flare Tip Velocity Calculation Method:

Actual Flare Tip Velocity (ft/sec) = (scf/hr)*(1 hr/3600 sec)/(flare tip area)

Heat Content Requirement Calculation Method:

For SO2, Q = (0.53)*(105)*(lb/hr SO2)

* Depressurizing and opening the vessel are sequential activities; therefore, the total hourly emission rate is the higher of the two activities

The basis of the example emission calculation (such as volume, concentration, pressure) are example conditions and should not be interpreted as representations of a specific facility or activity condition under 116.116(a). Individual activities in this MSS category which are performed may have slight variations in procedure or equipment configuration.

This Planned MSS Activity includes the shut in of the well to drop the pressure in the heater treater and then open the vessel to flare to bleed off as much pressure off as possible. Then all valves are closed and the remaining pressure will be opened to atmosphere.

Emissions vented to atmosphere from opening the emptied vessel are calculated using the Ideal Gas Law and are based on the entire tank volume venting to the atmosphere at the opening concentration. It is assumed that only one heater treater would be degassed at a time.

MSS Activity - Vacuum Trucks (Heater/Boiler Cleaning)

Emissions from vacuum trucks are estimated using the loading loss method of AP-42, Chapter 5.2: Transportation and Marketing of Petroleum Liquids, 1995. Calculations are performed based on the concentrations of the individual organic species since the wastes contain significant non-volatile content (i.e. water, solids). A truck can be loaded in one hour, therefore the emissions per loading activity reflect the lb/hr emission rate.

Notes:

Compressor engine is shutdown at least quarterly for maintenance. Each maintenance event lasts approximately 4 hours where the produced gas is routed to the flare.

Downtime: Venting Volume (scf/hr) is ratio of the permitted daily gas production rate and the compressor with largest HP rating.

Blowdown/Startups: Assume that blowdown/startup for the largest compressor occurs in one hour.

The basis of these emission calculations (i.e. volume, stream composition, frequency) are conditions used to establish a potential to emit and should not be interpreted as representations of a specific activity or condition under 30 TAC 116.116(a).

[2] Each EPN was modeled in SCREEN3 using a unit emission rate of 1 lb/hr. The Screen3 generic impact, Ghourly (µg/m3) / (lb/hr) was determined for each EPN. Emission rate from each source was multiplied by Ghourly. All maximum impacts were summed for each pollutant and evaluated against the appropriate NAAQS.

CONDITIONS AND DEFINITIONSCONDITIONS AND DEFINITIONSCONDITIONS AND DEFINITIONSCONDITIONS AND DEFINITIONSCaterpillar Methane Number represents the knock resistance of a gaseous fuel. It should be used with the Caterpillar Fuel Usage Guide for the engine and rating to determine the rating for the fuelspecified. A Fuel Usage Guide for each rating is included on page 2 of its standard technical data sheet.

RPC always applies to naturally aspirated (NA) engines, and turbocharged (TA or LE) engines only when they are derated for altitude and ambient site conditions.

Project specific technical data sheets generated by the Caterpillar Gas Engine Rating Pro program take the Caterpillar Methane Number and RPC into account when generating a site rating.

Fuel properties for Btu/scf calculations are at 60F and 14.696 psia.

Caterpillar shall have no liability in law or equity, for damages, consequently or otherwise, arising from use of program and related material or any part thereof.

FUEL LIQUIDSFUEL LIQUIDSFUEL LIQUIDSFUEL LIQUIDSField gases, well head gases, and associated gases typically contain liquid water and heavy hydrocarbons entrained in the gas. To prevent detonation and severe damage to the engine, hydrocarbonliquids must not be allowed to enter the engine fuel system. To remove liquids, a liquid separator and coalescing filter are recommended, with an automatic drain and collection tank to preventcontamination of the ground in accordance with local codes and standards.

To avoid water condensation in the engine or fuel lines, limit the relative humidity of water in the fuel to 80% at the minimum fuel operating temperature.

EMIT Technologies, Inc. warrants that the goods supplied will be free from defects in workmanship by EMIT Technologies, Inc. for a period of two (2) years from date of shipment. EMIT Technologies, Inc. will not be responsible for any defects which result from improper use, neglect, failure to properly maintain or which are attributable to defects, errors or omissions in any drawings, specifications, plans or descriptions, whether written or oral, supplied to EMIT Technologies, Inc. by Buyer.

Catalyst performance using an EMIT Air/Fuel ratio controller is dependent upon properly defined set-points, variable with engine and fuel gas composition. Air/fuel ratio controller performance is guaranteed, but not limited, to fuel gas with a HHV content of 1400 BTU/SCF.

Catalyst performance will be guaranteed for a period of 1 year from installation, or 8760 operating hours, whichever comes first. The catalyst shall be operated with an automatic air/fuel ratio controller. The performance guarantee shall not cover the effects of excessive ash masking due to operation at low load, improper engine maintenance, or inappropriate lubrication oil. The performance guarantee shall not cover the effects of continuous engine misfires (cylinder or ignition) exposing the catalyst to excessive exothermic reaction temperatures. In most cases, excluding thermal deactivation, catalyst performance is redeemable by means of proper washing (refer to EMIT Catalyst/Silencer Housing Manual for element wash information, or contact a local EMIT Sales representative).

The exhaust temperature operating range at the converter inlet is a minimum of 600°F for oxidation catalyst and 750 ˚F for NSCR catalyst, and a maximum of 1250°F.

If a properly functioning, high temperature shut down switch is not installed, thermal deactivation of catalyst at sustained temperatures above 1250˚F is not covered. If excessive exposure to over oxygenation of NSCR catalyst occurs due to improperly functioning or non-existent Air/Fuel ratio control, then deactivation of catalyst is not warranted.

The catalyst conversion efficiencies (% reduction) will be guaranteed for engine loads of 50 to 100 percent. Standard Oxidation Catalyst conversion efficiencies (% reduction) will be guaranteed for fuel gas containing less than 1.5% mole fraction of non-methane, non-ethane hydrocarbons. Applications where fuel gas exceeds this level will require a Premium Oxidation Catalyst to maintain guaranteed VOC conversion efficiencies.

Engine lubrication oil shall contain less than 0.5 wt% Sulfated Ash with a maximum allowable specific oil consumption of 0.7 g/bhp-hr. The catalyst shall be limited to a maximum ash loading of 0.022 lb/ft3. Phosphorous and zinc additives are limited to 0.03 wt%. New or Reconstructed engines must operate for a minimum of 50 hours prior to catalyst installation, otherwise the warranty is void.

The catalyst must not be exposed to the following know poisoning agents, including: antimony, arsenic, chromium, copper, iron, lead, lithium, magnesium, mercury, nickel, phosphorous, potassium, silicon, sodium, sulfur, tin, and zinc. Total poison concentrations in the fuel gas must be limited to 0.25 ppm or less for catalyst to function properly.

Shipment - Promised shipping dates are approximate lead times from the point of manufacture and are not guaranteed. EMIT Technologies, Inc. will not be liable for any loss, damage or delay in manufacture or delivery resulting from any cause beyond its control including, but not limited to a period equal to the time lost by reason of that delay. All products will be crated as per best practice to prevent any damage during shipment. Unless otherwise specified, Buyer will pay for any special packing and shipping requirements. Acceptance of goods by common carrier constitutes delivery to Buyer. EMIT Technologies, Inc. shall not be responsible for goods damaged or lost in transit.

Terms: Credit is extended to purchaser for net 30 time period. If payment is not received in the net 30 timeframe, interest on the unpaid balance will accrue at a rate of 1.5% per month from the invoice date.

Order Cancellation Terms: Upon cancellation of an order once submittal of a Purchase Order has occurred, the customer will pay a 25% restocking fee for Catalyst Housings, Catalyst Elements, and Air/Fuel Ratio Controllers; 50% restocking fee for Cooler Top Solutions, Exhaust System Accessories, and other Custom Built Products; 100% of all associated shipping costs incurred by EMIT; 100% of all project expenses incurred by EMIT for Field Services.

CONDITIONS AND DEFINITIONSCONDITIONS AND DEFINITIONSCONDITIONS AND DEFINITIONSCONDITIONS AND DEFINITIONSCaterpillar Methane Number represents the knock resistance of a gaseous fuel. It should be used with the Caterpillar Fuel Usage Guide for the engine and rating to determine the rating for the fuelspecified. A Fuel Usage Guide for each rating is included on page 2 of its standard technical data sheet.

RPC always applies to naturally aspirated (NA) engines, and turbocharged (TA or LE) engines only when they are derated for altitude and ambient site conditions.

Project specific technical data sheets generated by the Caterpillar Gas Engine Rating Pro program take the Caterpillar Methane Number and RPC into account when generating a site rating.

Fuel properties for Btu/scf calculations are at 60F and 14.696 psia.

Caterpillar shall have no liability in law or equity, for damages, consequently or otherwise, arising from use of program and related material or any part thereof.

FUEL LIQUIDSFUEL LIQUIDSFUEL LIQUIDSFUEL LIQUIDSField gases, well head gases, and associated gases typically contain liquid water and heavy hydrocarbons entrained in the gas. To prevent detonation and severe damage to the engine, hydrocarbonliquids must not be allowed to enter the engine fuel system. To remove liquids, a liquid separator and coalescing filter are recommended, with an automatic drain and collection tank to preventcontamination of the ground in accordance with local codes and standards.

To avoid water condensation in the engine or fuel lines, limit the relative humidity of water in the fuel to 80% at the minimum fuel operating temperature.

EMIT Technologies, Inc. warrants that the goods supplied will be free from defects in workmanship by EMIT Technologies, Inc. for a period of two (2) years from date of shipment. EMIT Technologies, Inc. will not be responsible for any defects which result from improper use, neglect, failure to properly maintain or which are attributable to defects, errors or omissions in any drawings, specifications, plans or descriptions, whether written or oral, supplied to EMIT Technologies, Inc. by Buyer.

Catalyst performance using an EMIT Air/Fuel ratio controller is dependent upon properly defined set-points, variable with engine and fuel gas composition. Air/fuel ratio controller performance is guaranteed, but not limited, to fuel gas with a HHV content of 1400 BTU/SCF.

Catalyst performance will be guaranteed for a period of 1 year from installation, or 8760 operating hours, whichever comes first. The catalyst shall be operated with an automatic air/fuel ratio controller. The performance guarantee shall not cover the effects of excessive ash masking due to operation at low load, improper engine maintenance, or inappropriate lubrication oil. The performance guarantee shall not cover the effects of continuous engine misfires (cylinder or ignition) exposing the catalyst to excessive exothermic reaction temperatures. In most cases, excluding thermal deactivation, catalyst performance is redeemable by means of proper washing (refer to EMIT Catalyst/Silencer Housing Manual for element wash information, or contact a local EMIT Sales representative).

The exhaust temperature operating range at the converter inlet is a minimum of 600°F for oxidation catalyst and 750 ˚F for NSCR catalyst, and a maximum of 1250°F.

If a properly functioning, high temperature shut down switch is not installed, thermal deactivation of catalyst at sustained temperatures above 1250˚F is not covered. If excessive exposure to over oxygenation of NSCR catalyst occurs due to improperly functioning or non-existent Air/Fuel ratio control, then deactivation of catalyst is not warranted.

The catalyst conversion efficiencies (% reduction) will be guaranteed for engine loads of 50 to 100 percent. Standard Oxidation Catalyst conversion efficiencies (% reduction) will be guaranteed for fuel gas containing less than 1.5% mole fraction of non-methane, non-ethane hydrocarbons. Applications where fuel gas exceeds this level will require a Premium Oxidation Catalyst to maintain guaranteed VOC conversion efficiencies.

Engine lubrication oil shall contain less than 0.5 wt% Sulfated Ash with a maximum allowable specific oil consumption of 0.7 g/bhp-hr. The catalyst shall be limited to a maximum ash loading of 0.022 lb/ft3. Phosphorous and zinc additives are limited to 0.03 wt%. New or Reconstructed engines must operate for a minimum of 50 hours prior to catalyst installation, otherwise the warranty is void.

The catalyst must not be exposed to the following know poisoning agents, including: antimony, arsenic, chromium, copper, iron, lead, lithium, magnesium, mercury, nickel, phosphorous, potassium, silicon, sodium, sulfur, tin, and zinc. Total poison concentrations in the fuel gas must be limited to 0.25 ppm or less for catalyst to function properly.

Shipment - Promised shipping dates are approximate lead times from the point of manufacture and are not guaranteed. EMIT Technologies, Inc. will not be liable for any loss, damage or delay in manufacture or delivery resulting from any cause beyond its control including, but not limited to a period equal to the time lost by reason of that delay. All products will be crated as per best practice to prevent any damage during shipment. Unless otherwise specified, Buyer will pay for any special packing and shipping requirements. Acceptance of goods by common carrier constitutes delivery to Buyer. EMIT Technologies, Inc. shall not be responsible for goods damaged or lost in transit.

Terms: Credit is extended to purchaser for net 30 time period. If payment is not received in the net 30 timeframe, interest on the unpaid balance will accrue at a rate of 1.5% per month from the invoice date.

Order Cancellation Terms: Upon cancellation of an order once submittal of a Purchase Order has occurred, the customer will pay a 25% restocking fee for Catalyst Housings, Catalyst Elements, and Air/Fuel Ratio Controllers; 50% restocking fee for Cooler Top Solutions, Exhaust System Accessories, and other Custom Built Products; 100% of all associated shipping costs incurred by EMIT; 100% of all project expenses incurred by EMIT for Field Services.

CONDITIONS AND DEFINITIONSCONDITIONS AND DEFINITIONSCONDITIONS AND DEFINITIONSCONDITIONS AND DEFINITIONSCaterpillar Methane Number represents the knock resistance of a gaseous fuel. It should be used with the Caterpillar Fuel Usage Guide for the engine and rating to determine the rating for the fuelspecified. A Fuel Usage Guide for each rating is included on page 2 of its standard technical data sheet.

RPC always applies to naturally aspirated (NA) engines, and turbocharged (TA or LE) engines only when they are derated for altitude and ambient site conditions.

Project specific technical data sheets generated by the Caterpillar Gas Engine Rating Pro program take the Caterpillar Methane Number and RPC into account when generating a site rating.

Fuel properties for Btu/scf calculations are at 60F and 14.696 psia.

Caterpillar shall have no liability in law or equity, for damages, consequently or otherwise, arising from use of program and related material or any part thereof.

FUEL LIQUIDSFUEL LIQUIDSFUEL LIQUIDSFUEL LIQUIDSField gases, well head gases, and associated gases typically contain liquid water and heavy hydrocarbons entrained in the gas. To prevent detonation and severe damage to the engine, hydrocarbonliquids must not be allowed to enter the engine fuel system. To remove liquids, a liquid separator and coalescing filter are recommended, with an automatic drain and collection tank to preventcontamination of the ground in accordance with local codes and standards.

To avoid water condensation in the engine or fuel lines, limit the relative humidity of water in the fuel to 80% at the minimum fuel operating temperature.

EMIT Technologies, Inc. warrants that the goods supplied will be free from defects in workmanship by EMIT Technologies, Inc. for a period of two (2) years from date of shipment. EMIT Technologies, Inc. will not be responsible for any defects which result from improper use, neglect, failure to properly maintain or which are attributable to defects, errors or omissions in any drawings, specifications, plans or descriptions, whether written or oral, supplied to EMIT Technologies, Inc. by Buyer.

Catalyst performance using an EMIT Air/Fuel ratio controller is dependent upon properly defined set-points, variable with engine and fuel gas composition. Air/fuel ratio controller performance is guaranteed, but not limited, to fuel gas with a HHV content of 1400 BTU/SCF.

Catalyst performance will be guaranteed for a period of 1 year from installation, or 8760 operating hours, whichever comes first. The catalyst shall be operated with an automatic air/fuel ratio controller. The performance guarantee shall not cover the effects of excessive ash masking due to operation at low load, improper engine maintenance, or inappropriate lubrication oil. The performance guarantee shall not cover the effects of continuous engine misfires (cylinder or ignition) exposing the catalyst to excessive exothermic reaction temperatures. In most cases, excluding thermal deactivation, catalyst performance is redeemable by means of proper washing (refer to EMIT Catalyst/Silencer Housing Manual for element wash information, or contact a local EMIT Sales representative).

The exhaust temperature operating range at the converter inlet is a minimum of 600°F for oxidation catalyst and 750 ˚F for NSCR catalyst, and a maximum of 1250°F.

If a properly functioning, high temperature shut down switch is not installed, thermal deactivation of catalyst at sustained temperatures above 1250˚F is not covered. If excessive exposure to over oxygenation of NSCR catalyst occurs due to improperly functioning or non-existent Air/Fuel ratio control, then deactivation of catalyst is not warranted.

The catalyst conversion efficiencies (% reduction) will be guaranteed for engine loads of 50 to 100 percent. Standard Oxidation Catalyst conversion efficiencies (% reduction) will be guaranteed for fuel gas containing less than 1.5% mole fraction of non-methane, non-ethane hydrocarbons. Applications where fuel gas exceeds this level will require a Premium Oxidation Catalyst to maintain guaranteed VOC conversion efficiencies.

Engine lubrication oil shall contain less than 0.5 wt% Sulfated Ash with a maximum allowable specific oil consumption of 0.7 g/bhp-hr. The catalyst shall be limited to a maximum ash loading of 0.022 lb/ft3. Phosphorous and zinc additives are limited to 0.03 wt%. New or Reconstructed engines must operate for a minimum of 50 hours prior to catalyst installation, otherwise the warranty is void.

The catalyst must not be exposed to the following know poisoning agents, including: antimony, arsenic, chromium, copper, iron, lead, lithium, magnesium, mercury, nickel, phosphorous, potassium, silicon, sodium, sulfur, tin, and zinc. Total poison concentrations in the fuel gas must be limited to 0.25 ppm or less for catalyst to function properly.

Shipment - Promised shipping dates are approximate lead times from the point of manufacture and are not guaranteed. EMIT Technologies, Inc. will not be liable for any loss, damage or delay in manufacture or delivery resulting from any cause beyond its control including, but not limited to a period equal to the time lost by reason of that delay. All products will be crated as per best practice to prevent any damage during shipment. Unless otherwise specified, Buyer will pay for any special packing and shipping requirements. Acceptance of goods by common carrier constitutes delivery to Buyer. EMIT Technologies, Inc. shall not be responsible for goods damaged or lost in transit.

Terms: Credit is extended to purchaser for net 30 time period. If payment is not received in the net 30 timeframe, interest on the unpaid balance will accrue at a rate of 1.5% per month from the invoice date.

EMIT Technologies, Inc. warrants that the goods supplied will be free from defects in workmanship by EMIT Technologies, Inc. for a period of two (2) years from date of shipment. EMIT Technologies, Inc. will not be responsible for any defects which result from improper use, neglect, failure to properly maintain or which are attributable to defects, errors or omissions in any drawings, specifications, plans or descriptions, whether written or oral, supplied to EMIT Technologies, Inc. by Buyer.

Catalyst performance using an EMIT Air/Fuel ratio controller is dependent upon properly defined set-points, variable with engine and fuel gas composition. Air/fuel ratio controller performance is guaranteed, but not limited, to fuel gas with a HHV content of 1400 BTU/SCF.

Catalyst performance will be guaranteed for a period of 1 year from installation, or 8760 operating hours, whichever comes first. The catalyst shall be operated with an automatic air/fuel ratio controller. The performance guarantee shall not cover the effects of excessive ash masking due to operation at low load, improper engine maintenance, or inappropriate lubrication oil. The performance guarantee shall not cover the effects of continuous engine misfires (cylinder or ignition) exposing the catalyst to excessive exothermic reaction temperatures. In most cases, excluding thermal deactivation, catalyst performance is redeemable by means of proper washing (refer to EMIT Catalyst/Silencer Housing Manual for element wash information, or contact a local EMIT Sales representative).

The exhaust temperature operating range at the converter inlet is a minimum of 600°F for oxidation catalyst and 750 ˚F for NSCR catalyst, and a maximum of 1250°F.

If a properly functioning, high temperature shut down switch is not installed, thermal deactivation of catalyst at sustained temperatures above 1250˚F is not covered. If excessive exposure to over oxygenation of NSCR catalyst occurs due to improperly functioning or non-existent Air/Fuel ratio control, then deactivation of catalyst is not warranted.

The catalyst conversion efficiencies (% reduction) will be guaranteed for engine loads of 50 to 100 percent. Standard Oxidation Catalyst conversion efficiencies (% reduction) will be guaranteed for fuel gas containing less than 1.5% mole fraction of non-methane, non-ethane hydrocarbons. Applications where fuel gas exceeds this level will require a Premium Oxidation Catalyst to maintain guaranteed VOC conversion efficiencies.

Engine lubrication oil shall contain less than 0.5 wt% Sulfated Ash with a maximum allowable specific oil consumption of 0.7 g/bhp-hr. The catalyst shall be limited to a maximum ash loading of 0.022 lb/ft3. Phosphorous and zinc additives are limited to 0.03 wt%. New or Reconstructed engines must operate for a minimum of 50 hours prior to catalyst installation, otherwise the warranty is void.

The catalyst must not be exposed to the following know poisoning agents, including: antimony, arsenic, chromium, copper, iron, lead, lithium, magnesium, mercury, nickel, phosphorous, potassium, silicon, sodium, sulfur, tin, and zinc. Total poison concentrations in the fuel gas must be limited to 0.25 ppm or less for catalyst to function properly.

Shipment - Promised shipping dates are approximate lead times from the point of manufacture and are not guaranteed. EMIT Technologies, Inc. will not be liable for any loss, damage or delay in manufacture or delivery resulting from any cause beyond its control including, but not limited to a period equal to the time lost by reason of that delay. All products will be crated as per best practice to prevent any damage during shipment. Unless otherwise specified, Buyer will pay for any special packing and shipping requirements. Acceptance of goods by common carrier constitutes delivery to Buyer. EMIT Technologies, Inc. shall not be responsible for goods damaged or lost in transit.

Terms: Credit is extended to purchaser for net 30 time period. If payment is not received in the net 30 timeframe, interest on the unpaid balance will accrue at a rate of 1.5% per month from the invoice date.

Order Cancellation Terms: Upon cancellation of an order once submittal of a Purchase Order has occurred, the customer will pay a 25% restocking fee for Catalyst Housings, Catalyst Elements, and Air/Fuel Ratio Controllers; 50% restocking fee for Cooler Top Solutions, Exhaust System Accessories, and other Custom Built Products; 100% of all associated shipping costs incurred by EMIT; 100% of all project expenses incurred by EMIT for Field Services.
