This is a renewal of the Oregon Title V Operating Permit issued to Gas Transmission Northwest Corporation (GTN) on June 7, 2004 and scheduled to expire on January 1, 2009. A timely and complete application was submitted to the Department on October 23, 2007, so the current permit will remain in effect until the permit renewal is issued. 2. In accordance with OAR 340-218-0120(1)(f), this review report is intended to provide the legal and factual basis for the draft permit conditions. In most cases, the legal basis for a permit condition is included in the permit by citing the applicable regulation. In addition, the factual basis for the requirement may be the same as the legal basis. However, when the regulation is not specific and only provides general requirements, this review report is used to provide a more thorough explanation of the factual basis for the draft permit conditions. 3. The following administrative amendments were issued during the previous permit term: Date 04/27/2005 4. Permit revision or notification Administrative Amendment Brief explanation Incorporate emission factors from source testing A history of turbine replacements is shown in the table below. The turbine replacements in 2004 (unit B) and 2005 (Unit A) were not “like-for-like” replacements. The permit was modified, as discussed above, for the Unit B replacement. The Unit A replacement is addressed in this permit action by revising the emission limit in condition 12. Unit Unit A Unit B 5.

GTN is a natural gas transmission company operating a pipeline from the Canadian border through the states of Idaho, Washington, and Oregon to California. GTN’s dual mainline is 612.5 miles in length and includes 638.9 miles of 36-inch and 589.4 miles of 42-inch pipeline. Energy to move the gas is provided by 12 compressor stations located along the pipeline all of which are designed for remote, unattended operation from GTN’s Gas Control Center in Portland. FACILITY DESCRIPTION 7. Compressor Station 14 is located in Klamath County, Oregon, on Harpold Valley Road, 3 miles south of Bonanza. Compressor Station 14 contains two gas turbine-driven compressor units. Unit A is a Solar Mars 90S gas turbine, rated at 14,100 HP (ISO). Unit B is a Solar Titan 130S gas turbine rated at 19,500 HP (ISO). Station 14 structures include a control building, a compressor building which houses Units A and B, a lubricating oil storage building, a storage building, a motor control center building, a fuel gas building, gas scrubbers, a scrubber-separator, instrument buildings, and valve shelters. The facility was originally built in 1970. 8. During normal operation, turbines will occasionally suffer a mechanical breakdown or a turbine will be replaced for scheduled maintenance. In the event of a turbine breakdown or scheduled maintenance GTN will replace the disabled turbine with a “like” turbine or a turbine of similar function. A like for like replacement is defined as same manufacturer, same horsepower and same combustion system. The disabled turbine will then be sent back to the manufacturer to be refurbished. After the turbine is refurbished it is held as a replacement for other turbines in the system that may breakdown. This permit allows the replacement of a turbine without modifying this permit or going through public notice if all applicable permit limits are met including NSPS and PSD limits in accordance with OAR 340-218-0190(2)(b). Review Report/Permit No.: 18-0072-TV-01 Application Number: 22428 Page 7 of 13 EMISSIONS UNIT AND POLLUTION CONTROL DEVICE IDENTIFICATION 9. The emissions units, devices, activities, and pollution control devices at the facility include the following: Emission Unit Description EU ID Device Description Device ID Gas turbine-driven compressor units A Solar Mars 90S - 14,100 hp B Solar Titan 130S - 19,500 hp 14-A 14-B Aggregate Insignificant AI Aggregate Insignificant AI 9.a. 9.b. 9.c. 10.

Aggregate Insignificant - Emission sources which are insignificant in aggregate include; auxiliary generator, fugitive particulate emissions from parking areas and driveways and fugitive VOC emissions from seals, valves, flanges, and blowdowns. Categorically insignificant activities include the following: Constituents of a chemical mixture present at less than 1% by weight of any chemical or compound regulated under Divisions 20 through 32 of OAR Chapter 340, or less than 0.1% by weight of any carcinogen listed in the US Department of Health and Human Service's Annual Report on Carcinogens when usage of the chemical mixture is less than 100,000 pounds/year Evaporative and tail pipe emissions from on-site motor vehicle operation Distillate oil, kerosene, and gasoline fuel burning equipment rated at less than or equal to 2.0 million Btu/hr Natural gas and propane burning equipment rated at less than or equal to 2.0 million Btu/hr each Office activities Janitorial activities Personal care activities Groundskeeping activities including, but not limited to building painting and road and parking lot maintenance Instrument calibration Maintenance and repair shops Automotive repair shops or storage garages Air cooling or ventilating equipment not designed to remove air contaminants generated by or released from associated equipment Refrigeration systems with less than 50 pounds of charge of ozone depleting substances regulated under Title VI, including pressure tanks used in refrigeration systems but excluding any combustion equipment associated with such systems Bench scale laboratory equipment and laboratory equipment used exclusively for chemical and physical analysis, including associated vacuum producing devices but research and development facilities Temporary construction activities Warehouse activities Arson fires Air vents from air compressors Air purification systems Continuous emission monitoring vent lines Demineralized water tanks Pre-treatment of municipal water, including use of deionized water purification systems Electrical charging stations Fire brigade training Review Report/Permit No.: 18-0072-TV-01 Application Number: 22428 Page 8 of 13 Instrument air dryers and distribution Process raw water filtration systems Routine maintenance, repair, and replacement such as anticipated activities most often associated with and performed during regularly scheduled equipment outages to maintain a plant and its equipment in good operating condition, including but not limited to steam cleaning, abrasive use, and woodworking Electric motors Storage tanks, reservoirs, transfer and lubricating equipment used for ASTM grade distillate or residual fuels, lubricants, and hydraulic fluids On-site storage tanks not subject to any New Source Performance Standards (NSPS), including underground storage tanks (UST), storing gasoline or diesel used exclusively for fueling of the facilities fleet of vehicles Natural gas, propane, and liquefied petroleum gas (LPG) storage tanks and transfer equipment Storm water settling basins Pressurized tanks containing gaseous compounds Fire suppression and training Hazardous air pollutant emissions of fugitive dust from paved and unpaved roads except or those sources that have processes or activities that contribute to the deposition and entrainment of hazardous air pollutants from surface soils Health, safety, and emergency response activities Emergency generators and pumps used only during loss of primary equipment or utility service Non-contact steam vents and leaks and safety and relief valves for boiler steam distribution systems Non-contact steam condensate flash tanks Non-contact steam vents on condensate receivers, deaerators and similar equipment Oil/water separators in effluent treatment systems Combustion source flame safety purging on startup EMISSION LIMITS AND STANDARDS, TESTING, MONITORING, AND RECORDKEEPING 11. There have not been any new applicable requirements promulgated for this source during the last permit term, so the emission limits and standards are the same as those contained in the previous permit. A summary of the emission limits and standards along with the testing, monitoring, and recordkeeping requirements is provided below. 12. Facility wide requirements: Since the turbines were installed after 1970 the applicable requirements are OAR 340-208-0110(2) (20% opacity) and 340-226-0210(1)(b) (0.1 gr/dscf). 12.a. 12.b. 13. Testing Requirements: Particulate emissions are expected to be negligible when the turbines are operated on natural gas and therefore, no testing will be required. Monitoring Requirements: Because particulate emissions are expected to be negligible when these units combust natural gas the permittee is not required to conduct monitoring for opacity or grain loading when the permittee burns only natural gas. The permittee shall maintain monthly and annual records of natural gas usage. Facility wide requirements: The following general standards for preventing nuisances apply: 13.a. OAR 340-208-0210(2) is a requirement to take reasonable precautions to minimize fugitive particulate emissions. OAR 340-208-0300 prohibits nuisances. OAR 340-208-00450 prohibits the deposition of particulate matter larger than 250 microns in size upon another person’s property. 13.a.i. Testing Requirements: By definition, it is not possible to perform source emission tests on fugitive emission sources. Therefore, the permit does not include any testing requirements or compliance test methods. 13.a.ii. Monitoring requirements: Monitoring for this standard consists of maintaining a complaint log and resolving complaints. Review Report/Permit No.: 18-0072-TV-01 Application Number: 22428 Page 9 of 13 14. Turbine Units A and B: Since these units were installed after October 3, 1977 and the heat input at peak load is equal to or greater than 10.7 gigajoules per hour, the applicable requirements are under Subpart GG Standards of Performance for Stationary Gas Turbines - 40 CFR Part 60.333(b) (0.8 % Sulfur by weight in fuel), 40 CFR Part 60.332(a)(2) (228 ppmv NOx at 15% O2 dry for Unit A and 213 ppmv NOx at 15% O2 dry for Unit B). 14.a. Testing Requirements: These units have already undergone the initial performance test as required by 40 CFR Part 60.8 of the NSPS. Two additional tests for NOx and CO will be required during the permit term to verify emission factors. If a unit is replaced, an initial compliance test is required to verify compliance with the NSPS NOx limit. Compliance tests must be conducted using EPA Method 20 and they may be used as one of the emission factor verification tests. Tests conducted solely for the purpose of verifying emission factors may be performed using EPA Method 7e or CTM-034. 14.b. Monitoring Requirements: The permittee had been required to monitor fuel sulfur content in accordance with the May 8, 1996 custom fuel compliance monitoring schedule and the January 29, 1999 revision to the custom fuel compliance monitoring schedule approved by EPA Region X. This monitoring was contingent upon the use of pipeline quality natural gas. However, in 2006, 40 CFR Part 60, subpart GG was revised as follows: 60.334(3) Notwithstanding the provisions of paragraph (h)(1) of this section, the owner or operator may elect not to monitor the total sulfur content of the gaseous fuel combusted in the turbine, if the gaseous fuel is demonstrated to meet the definition of natural gas in 60.331(u), regardless of whether an existing custom schedule approved by the administrator for subpart GG requires such monitoring. The owner or operator shall use one of the following sources of information to make the required demonstration: (i) The gas quality characteristics in a current, valid purchase contract, tariff sheet or transportation contract for the gaseous fuel, specifying that the maximum total sulfur content of the fuel is 20.0 grains/100 scf or less; or (ii) Representative fuel sampling data which show that the sulfur content of the gaseous fuel does not exceed 20 grains/100 scf. At a minimum, the amount of fuel sampling data specified in section 2.3.1.4 or 2.3.2.4 of appendix D to part 75 of this chapter is required. 15. Turbine Units A & B: Under alternative operating scenario 2, any of these units may be replaced with new units of the same or different heat input rates as long as the emission levels are maintained below the PSEL, other limits and the applicable requirements under Subpart GG - Standards of Performance for Stationary Gas Turbines - 40 CFR Part 60.333(b) (0.8 % Sulfur by weight in fuel) and 40 CFR Part 60.332(a)(2) (STD ppmv NOx at 15% O2 dry) are met. 15.a. 15.b. Testing Requirements: An initial test as required by 40 CFR Part 60.8 on a replacement unit under alternate operating scenario 2 must be conducted within 60 days after achieving the maximum production rate at which the affected facility will be operated, but not later than 180 days after initial startup of such facility. Subsequent tests shall be performed one time per calendar year unless the results from the first source test or two subsequent source tests are less than 90% of the NOx emission limit for each individual unit, in which case no further testing will be required on that turbine during the permit term. In addition to the compliance tests, two tests for NOx and CO will be required during the permit term to verify emission factors. Results from the initial compliance tests may be used to meet the requirement for emission factor verification testing. Emission factor verification tests may be conducted using a non-reference method such as CTM034. Monitoring Requirements: See 14.b. Review Report/Permit No.: 18-0072-TV-01 Application Number: 22428 Page 10 of 13 16. Insignificant emissions units: As identified earlier in this Review Report, this facility has insignificant emissions units (IEUs) that include categorically insignificant activities and aggregate insignificant emissions, as defined in OAR 340-200-0020. For the most part, the standards that apply to IEUs are for opacity (20% limit) and particulate matter (0.1 gr/dscf limit). The Department does not consider it likely that IEUs could exceed an applicable emissions limit or standard because IEUs are generally equipment or activities that do not have any emission controls (e.g., small natural gas fired space heaters) and do not typically have visible emissions. Since there are no controls, no visible emissions, and the emissions are less than one ton per year, the Department does not believe that monitoring, recordkeeping, or reporting is necessary for assuring compliance with the standards. In addition, the insignificant emissions units at this facility are not subject to any NESHAP standards. PLANT SITE EMISSION LIMITS 17. Provided below is a summary of the baseline emissions rate, netting basis, and plant site emission limits. Pollutant PM PM10 SO2 NOx CO VOC a. tons/year 17.a. 17.b. 18. Baseline Emission Ratea 2.7 2.7 3.1 359 329 6.2 Netting Basisa Previous Proposed 2.7 2.7 2.7 2.7 3.1 3.1 359 201 329 217 6.2 6.2 Plant Site Emission Limit (PSEL)a Previous Proposed Increase 24 24 0 14 14 0 39 39 0 161 161 0 117 117 0 39 39 0 The baseline emission rate is the actual emissions during 1977. The netting basis is equal to the baseline emission rate plus or minus any adjustments made pursuant to Department rule. Because of a 265 ton increase in NO x emissions the permittee was required to go through New Source Review in 1994. A NOx netting basis was established in the New Source Review process. NOx emissions increased because of increased hours of operation and the 1984 Unit B turbine replacement. An air quality analysis was conducted by the permittee which demonstrated that, once the stack height was raised to 19.5 meters, the emission increases would not cause air quality levels in excess of any Ambient Air Quality Standards (AAQS) or Prevention of Significant Deterioration (PSD) increment, and will not have a significant impact (including visibility impairment and vegetation impact) within any Class I area. Stack height was raised to 19.5 meters in 1995. In 1999 when Unit B was replaced the stack was also replaced with a stack of lower height. Since the new stack would not disperse the NOx as demonstrated in the 1994 modeling the netting basis was lowered so that it is now equal to the baseline emission rate of 359 tons. Unassigned emissions were established in the last permit action. The unassigned emissions were not used, so they are being reduced to the significant emission rate in accordance with OAR 340-222-0045(3)(a): Unassigned Emissions (tons/yr) Pollutant PM/PM10 SO2 NOx CO VOC Previous 0 0 198 212 0 Proposed 0 0 40 100 0 Review Report/Permit No.: 18-0072-TV-01 Application Number: 22428 Page 11 of 13 SIGNIFICANT EMISSION RATE 19. The proposed Plant Site Emission Limits are equal to the previous Plant Site Emission Limits, thus there is no increase above the significant emission rates and no further air quality analysis is required. HAZARDOUS AIR POLLUTANTS 20. A major source is a facility that has the potential to emit more than 10 tons/year of any single HAP or 25 tons/year of combined HAPs. This source is not a major source of hazardous air pollutants. Using AP-42 emission factors (table 3.1-3), the maximum potential estimated emissions are: Hazardous Air Pollutant (HAP) Annual HAP Emissions - tons Acetaldehyde Acrolein Benzene Ethylbenzene Formaldehyde Naphthalene PAH Toluene Xylenes Total 21. 0.0418 0.0067 0.0125 0.0334 0.7422 0.0014 0.0023 0.1359 0.0669 1.0739 The NESHAP/MACT standard for combustion turbines (40 CFR Part 63, Subpart YYYY) could apply to this source. However, since this source is not a major source of HAPs Subpart YYYY does not apply. GENERAL BACKGROUND INFORMATION 22. No other permits are required for this facility by the Department. 23. This source is located in an area that is in attainment for all pollutants. COMPLIANCE HISTORY 24. The facility was inspected on the following dates during the last permit term: Inspection Date 8/15/06 September 2004 Results of Inspection In Compliance Department Actions No Action Necessary Review Report/Permit No.: 18-0072-TV-01 Application Number: 22428 Page 12 of 13 SOURCE TEST RESULTS 25.

The permit was placed on public notice from April 17, 2008 to May 21, 2008. No comments were received in response to the Public Notice. A proposed permit was sent to EPA for a 45 day review period. The Department requested and EPA agreed to an expedited review of 5 days as there were no substantive or adverse comments during the comment period. The permit was issued following EPA’s review. Since EPA did not object in writing, any person may petition the EPA within 60 days after the expiration of the EPA's 45-day review period to make such objection. Any such petition must be based only on objections to the permit that were raised with reasonable specificity during the public comment period provided for in OAR 340-218-0210, unless the petitioner demonstrates that it was impracticable to raise such objections within such period, or unless the grounds for such objection arose after such period.
