REVIEWER: Poul E. Paulsen CONTROL ENGINEER: Dennis M. Myers PROJECT DESCRIPTION K N Front Range Gathering, Inc. has proposed to modify the Hudson natural gas transmission compression station located in Section 23, T-2-N, R-65-W in Weld County, Colorado. This modification consists of the installation of one (1) natural gas fired engine with a non- selective catalytic converter and the use of a air/fuel ratio controller. SUMMARY OF EMISSIONS in Tons/Year Pollutant Existing Natural Gas TOTAL Facility Compressor Oxides of Nitrogen 1168.9 14.0 1,182.90 Carbon Monoxide 147.9 21.1 169.00 Volatile Organic 46.9 3.5 50.40 AMBIENT IMPACT ANALYSIS in micrograms/cubic meter (ug/m3) Pollutant Averaging New Source Background Total Ambient Model Time Contribution Concentration Impact Standard Name Oxides of Nitrogen Annual 11.3 7.6 18.9 100.0 SCREEN Carbon Monoxide 8 Hr. 148.0 2320.0 2,468.010,000.0 SCREEN The maximum concentration,due to the contribution of this source modification, is estimated to occur at 102 meters from the facility boundary. This source is located in an attainment area for Oxides of Nitrogen (NOr) and Carbon Monoxide. REGULATORY SOURCES STATUS This modification is considered a synthetic minor air emission source due to the control devices applied. This facility is presently a major source because the emissions are above 250 tons per year (TPY) emissions. Monitoring of engine operating parameters and federally 'enforceable emission limits, are required to ensure that emissions do not meet or exceed the 40 TPY significant threshold required for a major modification. Operating conditions that cause an increase in the potential to emit above the 40 ton per year of NO, emission threshold will result in this source being subject to major stationary source requirements outlined in Regulation Number 3, Part B, Section IV.D.3 regarding Prevention of Significant Deterioration. There are no specific NO,emission standards for internal combustion engines. Pubic notice is required because the uncontrolled annual emissions are grater then 40 TPY. This facility will be subject to the operating permit program because the potential to emit exceeds 100 TPY. The Division has determined that this source will meet all applicable regulations. t - - • 4 - 1 - - - - - - - - - i , I i i >( rs 1 Z i I H - - Z G c P : G U O 4 m .n.w I \ o�ov: (...1?.. _d -- il 1 I1 i )I i �z � I I •r, L :1L I I ICD = I F VIa 7y� I U h $ �a T I `1 1I I F t R I CO ) J I T9 O o w ll i CO O OS ` "Z 1 12 rj _'� , '� ___r I 0 j � _ i , �, r i W Q w Q _• %' _ _ O CC o • . , ..„i_ _,t�S Jri °T.__wniu %// 4 Z. 5 i • I ! ; 1 12. ? iq i I i: ? uE • • _ = C.` I � E - Z 4 / O r r I /�'SJ`�4 Q a U X = r\_,•outosur ca uwo cn I I �• N ■ -- L L ..

The Vallmar station is ten miles to the west of the Hudson Facility, both located in Weld County. The Hudson/North Hudson Facility is a Major Source, grandfathered for PSD. Initial operations at the facility started in 1973, and were permitted on April 2, 1974. Because the actual emissions are less then the 40 tpy NOx and 100 tpy CO significant levels, this is a minor modification. The NOx and CO increases are 28 and 42 tpy respectively. Because the engines will be equipped with NSCR, this modification would be considered a synthetic minor for a major modification. Public notice will be required because the uncontrolled annual emissions are greater than to 40 tpy significant threshold required for a major modification. The permits will be issued with a condition that it will not be considered a synthetic minor modification until public comment is completed and any necessary changes resulting have been addressed. The screening model results, indicate a possible class II increment exceedance (25 µg/m3 - annual average) . This impact screening modeling (Screen II Model) was performed only on the new source. The contribution is estimated to occur with a maximum concentration at 102 meters from the facility. The screening model used indicates a conservative contribution concentration estimate due to the model's high degree of uncertainty at the minimum distance which is 100 meters. These models also assume that all NOx has been converted to NO2 which may also be a conservative assumption. An ozone limiting model would probably show a more realistic NO2 annual concentration. Because these engines will employ a non-selective catalytic converter and use a air/fuel ratio controller to insure that the engine stays in the narrow range for control, a stack test will be required. The applicant has indicated a control efficiency of at least 75%. The Division's emission analysis which was based on AP- 1145,70/ 7 RN Front Range Gathering Hudson/North Hudson Compressor Station Permit Application 94RE338 (1-2) Page Number 2 42, Standard Rich-burn emission factors indicate a 80% reduction in NOx and a 65% reduction in CO. This facility is located in an attainment area for Nitrogen Oxides and Carbon Monoxide. An operating permit is required for this facility and it is scheduled for the first third which will be due March 1, 1995. I have requested that the applicant clarify the ownership of the facility. Our records indicate that Panhandle Eastern Pipeline is the operator. A copy of this application will be sent to EPA. 123/0048/15-16 • APCD Preliminary Analysis Page _2_ of 4rl Internal Combustion Natural Gas Engine Emissions Permit Number :94WE338-1 Date :08/17/94 Applicant :KN Front Range Gathering App Date:05/19/94 Project Descript:Hudson Compressor Station Location :SW SW Section 23, T2N, R65W Mfr./model :Waukesha, Model L7042GU Horsepower 727 Annual Operation: 8760.0 Hrs/Yr Fuel Consumption: 46.00 SCFe6/Yr Capacity Factor. : 100.00% 5,251 SCF/Hr Heat Rate • 7584.2 BTU/HP-HR Fuel Flow Rate. .: 5.51 BTUe6/Hr Heating Value : 1,050 BTU/SCF Uncontrolled Rate Emission Controlled Rate Potential AP-42, Standard Rich Burn - Uncontro Factor Pollutant g/BHP-hr Ton/Yr g/BHP-hr Ton/Yr Lb/SCFe6 Lb/Hr EFF Ton/Yr NOx • 10 70.22 2.00 14.04 610.44 3.21 80.00% 70.2 CO 8.6 60.39 3.00 21.06 915.66 4.81 65.12% 60.4 Hydrocarbons • 1.2 8.43 1.20 8.42 366.27 1.92 0.02% 8.4 NMHC (VOC) 0.14 0.98 0.50 3.51 152.61 0.80 0.00% 3.5 Methane • 1.1 7.44 0.70 4.91 213.65 1.12 33.98% 7.4 Formaldehyde(HAP) 0.02 0.659 0.003 SO2 • 0.002 0.01 0.002 0.01 0.61 0.00 0.02% 0.0 PM • 0.16 1.1 0.16 1.1 48.8 0.26 0.02% 1.1 Control Device :NSCR- Three way catalyst Emission Factor :Manufacturers - Controlled Standard Rich Burn Engine * ** Min, max dist: 100.00 500 [meters] Stack Height: 14.00 [Feet] = 4.27 [Meters] Stack Diameter: 1.00 [Feet] = 0.30 [Meters] Exit Velocity: 1541.66 [Ft/Min]= 7.83 [M/Sec] Exit Temperature: 1030.00 [0 F] = 827.59 [Kelvins] Flowrate: 1212.00 [ACFM] = 1541.66 [Ft/Min] Model Impact Analysis Model : SCREEN-2 - Rural Max.

Colorado Department of Health 4300 Cherry Creek Drive South Denver, CO 80222-1530 RE: Hudson/N.Hudson Compressor Stations-Transfer of Ownership On behalf of K N Front Range Gathering System,we are requesting a transfer of ownership for the North Hudson Compressor Station located in Weld County, Colorado. On behalf of Wattenberg Transmission Limited Liability, we are also requesting a transfer of ownership for the Hudson Compressor Station. These properties are contiguous and were purchased from Panhandle Eastern Pipeline effective April 1, 1993. As of this date,K N assumes all liability for meeting the requirements specified in permits pertaining to this property. The status of all permit requirements have been reviewed for this facility and we have found that all required APENs have been submitted and are up-to-date. Attached for your information are copies of all APENs which were submitted to the Colorado Department of Health on December 29, 1993, as well as the AIRS report for this facility. At that time, a transfer of ownership was requested and has just recently been reviewed for processing. We have been working with Nicholas Schmidt of the CDH, and all of his concerns regarding this issue have been met. If you have any questions or comments concerning this request, please feel free to call me at 763-3571. Thank you for your help. Michele A.

Two Waukeshas(Model#L7042 -GU)are being moved from the Vollmar Station(Weld County)to the Hudson/Hudson North Station, located in Section 23, R2N, T65W in Weld County, Colorado(see attached map). The existing Hudson/Hudson North Station consists of four Clark compressor engines, one Caterpillar compressor engine, and one Waukesha compressor engine(see Table 1). The four Clark compressor engines were permitted first in 1974 and are a major stationary source because of NOx emissions. The Waukesha engine was installed in 1981, and the Caterpillar was installed in 1985. The most recent engine installation in 1985 constituted‹najor modification i.e., greater than 40 TPY increase AA) f T in NOx emissions); therefore, the modification requested now only concerns the addition of the two MS;Ar.• Waukesha engines. 1?�,�/kfrv' A three-way catalytic converter will be added to each of the relocated Waukesha engines. These converters will control NOx, CO, and VOC emissions. VOC and CO emissions will increase with this control over the previously permitted levels for these engines. Whether with engine fuel/air ratio readjustment and the addition of the catalyst, there will be a real increase or decrease in CO and VOC emissions is speculative. The catalytic converters will be installed and a stack test will be performed to demonstrate the effectiveness of this control. With these converters, the two engines cumulatively will emit less than the following significant emission thresholds: CO- 100 TPY,NOx- 40 TPY, VOCs-40 TPY. Therefore, the addition of these two engines will be a minor modification. The engines being moved were previously permitted to operate 10 miles to the west in Weld County. With the move, catalysts will be installed on them, controlling the NOx by at least 75 percent. Clearly there will be a net decrease in NOx emissions of about 100 tons per year and basin wide NOx concentrations with this source relocation. Because of this, no NOx dispersion modeling is performed. We believe the VOC and CO emission change to be either a real decrease or a sufficiently small increase that impacts will be less than de minimis. Therefore, no modeling is performed for CO or ozone.

Colorado SO_222X Yr; ')}iX 2t)(4) FA\ ()XX 2tR A _ Mr. Jim Geier May 12, 1994 Page 2 The engines are subject to Colorado Regulation 1 and therefore the opacity of their emissions must be below 20 percent. This limit is of little concern, because natural gas-fueled engines do not have visible plumes. Because the engines burn natural gas, SO2 and PMI° emissions will be negligible. Therefore, meeting the SO2 and PM,()requirements of Regulation 1 is not a concern. This application package consists of • Application form • Criteria APEN forms(two) • Ha7ardous air pollutant APEN forms(two) • Description of emission sources • Estimate of emissions at capacity with controls(catalytic converter) • Total emissions summary • Check for$200 for application processing • Operating/Maintenance Plan • Recordkeeping Plan An operating and maintenance plan is included to insure effective operation of the catalysts. A recordkeeping plan is also included to demonstrate compliance with anticipated operating rate permit limits.

For these tests the engines will be operated at 90 percent of capacity or higher. If the system does not meet the NO. and CO emission rates of 2 g/hp-hour and 3 g/hp-hour respectively,the catalyst will be replaced. Recordkeeping Requirements RN Energy will perform the following recordkeeping for compliance purposes: • Because the engines will be permitted to operate at capacity there will be no need to track operating rates for compliance purposes. Fuel consumption will be recorded monthly to estimate annual actual emissions from the engines. A thermal efficiency of 35 percent will be assumed to estimate engine power output from fuel consumption. • Replacement of spark plugs and oxygen sensor will be documented. • Quarterly point source testing of CO and NO„will be documented. , .
