### 4.2.4-658 2I. DESCRIPTION OF PROPOSAL Hill Air Force Base is planning to install a 10' X 10' X 20' blast mediabooth complete with the blast/reclaimer assembly comprising of a cyclone separator, a storage hopper, a lowprofile hopper, and a blast machine. The cyclone blower vacuums blasting residue from the low profile hopper in the enclosure floor. As the residue enters the cyclone, the cyclone separates undamagedblast media from the other debris and dust. The undamaged, reusable mediadrops through the cyclone's vibrating screen into the storage hopper. The reclaimedmedia from the storage hopper feeds into the blast machine. The debris and dust from the cyclone are drawn into the dust collector. The blast media will use Poly Vplasticmedia. The components to be blasted include aircraft wheels, panels, ladders, engine run screens, tool boxes, carts, and ground support equipment. This booth will be installed at Building 48 and will be operated a maximum of 2080 hours per year. II. EMISSION SUMMARY ProposedEmissions (from Media Blast Booth) Particulate 1.2 ton/yr PMIO 1.0 III. BEST AVAILABLE CONTROL**TECh~OLOGY** (BACT) ANALYSIS The media blast booth is equipped with a 24 cartridge dust collector assembly with a 99.9% collection efficiency for particulate matter larger than 1 micron. The Engineering Section recommends that BACT for the media blast booth be the following: A. Proper operation andmaintenance of the cartridge dust collector B. 10% opacity C. PM10 emission concentration of 0.016 grain/dscf (68°F, 29.92" Hg) D. PMIO emission rate of 0.93 lbs/hr IV. APPLICABILITY OF FEDERAL REGULATIONS AND UTAH AIR CONSERVATION RULES This Notice of Intent is for a minor modification to a major source. It is not a newmajor source or a major modification. The following federal regulations and state rules have been examined to determine their applicability to this Notice of Intent: 1. R307-1-3.1, UAC

- Notice of Intent required for a modified source. This rule applies. 2. R307-1-3.1.5, UAC

### 4.2.4-6594. R307-1-3.1.8 (C), UAC

- Approval of the UAQB is required before the Executive Secretary can approve a source under Section 3.6.5 which consumes more than 50% of a PSD increment. This rule does not apply to this NOI because a PSD permit is not being issued. 5. R307-1-3.1.8 (D), UAC

- Enforceable offset of 1.2:1 required for new sources or modifications which wouldproduce an emission increase greater than or equal to 50.00 tons per year of any combination of PMIQ, S02' andNO,. This is required in Salt Lake, Davis, andUtah Counties and in any area that impacts these three counties as defined in the rule. The effective date is November 15, 1990. This emission point emits less than 50.00 tons per year of combined PM:o, S02' and NO,. Therefore, this rule does not apply. 6. R307-1-3.1.8 (D), UAC

- Enforceable offset of 1:1 required for new sources or modifications which wouldproduce an emission increase greater than or equal to 25.00 tons peryear of any combination of PM1o, S02' and NO,. This is required in Salt Lake, Davis, and Utah Counties and in any area that impacts these three counties as defined in the rule. The effective date is November 15, 1990. This emissionpoint emits less than 25.00 tons per year of combined PMIQ, S02' and NO,. Therefore, this rule does not apply. 7. R307-1-3.1.9, UAC

- Rules for relocation of temporary sources. This source is a permanent source. Therefore, this rule does not apply. 8. R307-1-3.2.1, UAC

- Particulate emission limitations for existing sources which are located in a nonattainment area. This rule has been supersededby the PM10 SIP, except for Weber County. The effective date is November 15, 1990. The sources listed in Weber County are as follows: A. Farmers Grain Coop B. Fife Rock Products C. Interpace Corporation D. Parsons Asphalt Plant E. Pillsbury Compariy F. Teledyne Incinerator G. Gibbons and Reed Asphalt This source is not listed in the SIP. Therefore, this rule does not apply. 9. R307-1-3.3.2, UAC

- Review requirements for new major sources or majormodifications which are located in a nonattainment area or which impact a nonattainment area. This Notice of Intent does not represent a new major source or a major modification. Therefore, this rule will not apply. 10. R307-1-3.5, UAC

- Emission inventory reporting requirements. This rule requires any source which emits 25 tons ormore per year of any pollutant to submit an emission inventory to the Division of Air Quality at least every thirdyear or as determined necessary by the Executive Secretary. Hill Air Force Base must comply with this rule. 11. R307-1-3.6.3, UAC

### 4.2.4-669I. DESCRIPTION OF PROPOSAL Hill Air Force Base 

### is planning to replace a 300 KW diesel generator with a 600 KW diesel generator in Building 575. The generator being replaced was grandfathered. The new generator 

### is a CaterpillarModel No. 3412 DITA emergency diesel generator. This generator will serve as a backup for emergencypower to Industrial Waste Water Treatment Plant equipment. This generator will be used a maximum of 100 hours per year. This generator will use an existing 2,000 gallon above ground diesel storage tank and a 250 gallon day tank for fuel supply. II. EMISSION SUMMARY Existing Emissions (from existing emergency generator in Building 575) Particulate 0.04 ton/yr PM10 0.02 S02 0.04 NO. 0.62 CO 0.13 VOC 0.05 Aldehydes 0.01 Proposed Emissions (fromnew generator) Particulate 0.09 ton/yr PMIO 0.05 S02 

### O.OB NO. 1.24 CO 0.26 VOC 0.10 Aldehydes 0.02 Net Increase in Emissions Particulate 0.05 ton/yr PMIO 0.03 S02 0.04 NO. 0.62 CO 0.13 VOC 0.05 Aldehydes 0.01
III. BEST AVAILABLE CONTROL TECHNOLOGY (BACT) ANALYSIS BACT for the generator set would be the use of a catalytic converter to control emissions of CO, NO. and VOC. Also, a natural gas fueled generator would be considered BACT rather than a diesel fueled generator. In this case, the generator is proposed to be a stand-by generator that will only operate in emergency situations and will only be operated for approximately 100 hours per year. The addition of a control device to the generator to reduce emissions would be a large economic burden. The Engineering Section is recommending that BACT for the generatorbe proper operation and maintenance and 20% opacity.

### 4.2.4-679I. DESCRIPTION OF PROPOSAL Hill Air Force Base is planning to replace an 80 KW diesel generator with a 225 KW diesel generator inBuilding 565. The new generator is a Caterpillar Serial No. 2AJOO536 emergency diesel generator. This generator will serve as a backup for emergencypower to Weber andDavis Countywater pumps. This generator will be used a maximum of 60 hours peryear. This generatorwill use an existing 1,000 gallon above ground diesel storage tank for fuel supply. This Approval Order will replace anAproval Order dated September 18, 1980, which also included a 15 KW diesel generator in Building 1151 and a 110 gallon underground fuel storage tank. II. EMISSION SUMMARY

Existing Emissions (from existing emergency generator in Building 565) Particulate PM,o S02 NOx CO VOC Aldehydes 0.01 0.00 0.01 0.10 0.02 0.01 0.00 ton/yr

Pro Emissions (from new gene posed rator) Particulate PM10 S02 NOx CO VOC Aldehydes 0.03 0.02 0.03 0.47 0.10 0.04 0.01 ton/yr

Net Increase in Emissions Particulate 0.02 ton/yr PM10 0.02 S02 0.02 NO. 0.37 CO 0.08 VOC 0.03 Aldehydes 0.01 An entry of 0.00 does not mean the emissions are zero; it is intended to mean negligible emissions. III. BEST AVAILABLE CONTROL TECHNOLOGY (BACT) ANALYSIS BACT for the generator set would be the use of a catalytic converter to control emissions of CO, NO. andVOC. Also, a natural gas fueled**generato~** wouldbe consideredBACT rather than diesel fueled generator. In this case, the generator is proposed to be a stand-by generator that will only operate in emergency situations and will only be operated for approximately 100 hours per year. The addition of a control device to the generator to reduce emissions is not justified.

3 

### 4.2.4-680The Engineering Section is recommending that BACT for the generatorbe proper operation andmaintenance and 20% opacity. IV. APPLICABILITY OF FEDERAL REGULATIONS AND UTAH AIR CONSERVATION RULES This Notice of Intent is for a minor modification to a major source. It is not a new major source or a majormodification. The following federal regulations and state rules have been examined to determine their applicability to this Notice of Intent: 1. R307-1-3.1, UAC

- Approval of the UAQB is requiredbefore the Executive Secretary can approve a source under Section 3.6.5 which consumes more than 50% of a PSD increment. This rule does not apply to this NOI because a PSD permit is not being issued. 5. R307-1-3.1.B (D), UAC

- Enforceable offset of 1.2:1 required for new sources ormodifications which wouldproduce an emission increase greater than or equal to 50.00 tons peryear of any combination of PM\O' S02' andNO.. This is required in Salt Lake, Davis, andUtah Counties and in any area that impacts these three counties as defined in the rule. The effective date is November 15, 1990. This emissionpoint emits less than 50.00 tons per year of combined PMIO, S02, and NO.. Therefore, this rule does not apply. 6. R307-1-3.1.B (D), UAC

- Enforceable offset of 1:1 required for new sources or modifications which wouldproduce an emission increase greater than or equal to 25.00 tons per year of any combination of PM10' S02' and NO.. This is required in Salt Lake, Davis, andUtah Counties and in any area that impacts these three counties as defined in the rule. The effective date is November 15, 1990. This emissionpoint emits less than 25.00 tons per year of combined PM\O' S02' and NO.. Therefore, this rule does not apply. 7. R307-1-3.1.9, UAC- Rules for relocation of temporary sources. This source is a permanent source. Therefore, this rule does not apply. B. R307-1-3.1.12, UAC

### 4.2.4-694The Division of Air Quality guidelines do not call for this source to be modeled for anypollutant. The Divisionhas found through experience that, because of the small quantity of emissions involved and the conservative predictions made bymodeling, a source or emissionpoint of this small size is very unlikely to cause a newviolation of the NAAQS. However, it will make a small contribution to the existing violation for ozone of the NAAQS. 27. 40 CFR 60.14, Definition of Modification

- Anyphysical or operational change to an existing facility which results in an increase in the emission rate to the atmosphere of anypollutant to which an NSPS standard applies.

## EmergencyDieselGeneratorsB1dgs575& 

## 14 1. Project Description: Three emergency generators are planned. An eXisting 300 KW generator in Bldg 575 will be replaced with a Catterpillar's Model 3412 DITA or equal 600 KW generator using the existing 2,000 gallons diesel above ground storage tank and a 250 gallon day tank. This generator will serve as a back-up to Industrial Waste Water Treatment Plant equipment in the event of power outage. A 500 KW CaterpillarModel 3412 DIT or approved equal together with a 5,000 gallons above ground diesel storage tank and a 400 gallon day tank at Bldg 14will serve as a back-up for the Airfield Runway and Beacon Lights. In addition an existing 350 KW generator will be relocated from Bldg221 to Bldg 14. 2. Pollutant Emissions: The source of air pollution from these projects involve exhaust emiSSIOns from diesel engines. Evaporative emissions from diesel tanks are negligible. Since these generators serve only as back-up power units, they will be in operation only during power outage and for periodic maintenance start-ups. Based on operating history of emergency generators on base, we estimate approximately an average of 40 hours and a maximum of 80-100 hours run time for each generator per year. Emissions are calculated using the EPA publication, AP-42, Compilation of Air Pollutant Emission Factors. TotalKW= 1,450 ExistingK\V

## MediaBlastBoothBldg48 1. Project Description: The media blast booth is a 10'XI0'X20' metal enclosure complete with the blast/reclaimer assembly comprising of a cyclone seperator, a storage hopper, a low profile hopper, and a blastmachine. The cyclone blower vacuums blasting residue from the low profile hopper on the enclosure floor. As the residue enters the cyclone, the cyclone separates undamaged blast media from the other debris and dust. The undamaged, reusable media drops through the cyclone's vibrating screen into the storage hopper. The reclaimed media from the storage hopper gravity feeds into the blast machine. The debris and dust from the cyclone are drawn into the dustcollector. A schematicofthe mediablastunitis Atch 1. Atch 2 shows blast/reclaimer assembly. The blast media shall be Poly V plastic media. The components to be blasted include aircraft wheels, panels, ladders, engine run screens, tool boxes, carts and ground support equipment. 2. AirEmissions: Particulate emissions will be controlled using high efficiency 24 cartridge dust collector assembly.

## EmergencyDieselGeneratorBldg565 1. Project Description: An existing 80 KW generator approved under an Approval Order dated 18 Sept. 1980is replaced with a CaterpillarSerial No. 2AJ00536, 225 KW emergency diesel generator using an existing 1,000 gallon above ground diesel tank. This generator serves as a back-up emergency power to 

## Weber and Davis water pumps. 2. Pollutant Emissions: The source ofair pollution from this project involve exhaust emISSIons from diesel engine. Evaporative emissions from diesel tank are negligible. Since, this generator serves only as a back-up powerunit, this will be in operation only during power outage and·for periodic maintenance startups. Forunits under 250KW, we run them only for an hourpermonth to ensure their availability in the event ofpower failure. Based on this, we estimate approximately less than 30 hours and a maximum of 60 hours run time per year. Emissions are estimated using the EPA publication. AP-42, Compilation of

.Air Pollutant EmissionFactors.
