I.	 DESCRIPTION OF PROPOSAL 

Hill Air Force Base is planning to install a 10' X 10' X 20' blast media booth 

complete with the blast/reclaimer assembly comprising of a cyclone separator, 

a storage hopper, a low profile 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 

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 feeds into the blast machine. The 

debris and dust from the cyclone are drawn into the dust collector. 

The blast media will use Poly V plastic media. 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 

Proposed Emissions (from Media Blast Booth)

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 and maintenance 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 new major source or a major modification. The following federal 

regulations and state rules have been examined to determine their 

applicability to this Notice of Intent:

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 would produce an emission 

increase greater than or equal to 50.00 tons per year of any 

combination of PMIQ, 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 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 would produce an emission increase 

greater than or equal to 25.00 tons per year 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 emission point emits less than 25.00 tons per year of 

combined PMIQ, S02' and NO,. Therefore, this rule does not apply.

UAQB to promulgate a plan and implement rules to eliminate any PSD 

increment violations which occur in the state. No known 

violations have yet occurred. This proposed Notice of Intent will 

consume negligible amounts of increment. 

14.	 R307-1-3.8, UAC - Stack height rule. This rule limits the 

creditable height of stacks to that height determined to be good 

engineering practice. The formulas used to determine good 

engineering practice are found in 40 CFR 51.100. A deminimus 

height of 65 meters (213.2 feet) is allowed. Hill Air Force Base 

has no stacks which exceed 65 meters in height. It is in 

compliance with this rule. 

15.	 R307-1-3.11, UAC - Visibility screening analysis requirements. 

This rule requires all new major sources or major modifications to 

undergo a visibility screening analysis to determine visibility 

impact on any mandatory Class I area. This Notice of Intent does 

not represent a new major source or a major modification under

B.	 Any source that constructs after the promulga~ion of this 

rule two or more emission points, which may i~terfere with 

6 

4.2.4-662 
VEO's, shall install an opacity monitor on each stack. 

This emission point does not require a CEMS. 

20.	 R307-1-4.7, UAC - Unavoidable breakdown reporting requirements. 

This rule applies. Section 4.7.1 discusses reporting 

requirements. A breakdown for any period longer than 2 hours must 

be reported to the Executive Secretary within 3 hours of the 

beginning of the breakdown, if reasonable, but in no case longer 

than 18 hours after the beginning of the breakdown. A written 

report is required within 7 calendar days. The report shall 

include the estimated quantity of pollutants (total and excess) . 

Section 4.7.2 discusses penalties. 

21.	 R307-1-4.9, UAC - Revi.ew requirements for volatile organic 

compound (VOC) sources located in a nonattainment area for ozone 

constructed in 1980 or earlier. This process is not covered in 

this rule. 

22.	 R307-1-4.10, UAC - Abrasive Blasting Requirements - Opacity 

limitations and performance standards for abrasive blasting - This 

regulation applies to this source. The performance standards 

require the use of one of the following: 

A.	 Confined blasting 

B.	 Wet abrasive blasting 

C.	 Hydroblasting 

D.	 Unconfined blasting using certified grit 

If the source complies with one of the above and is located in an 

attainment area, the opacity limitation is 40%. If the source 

complies with one of the above and is located in a nonattainment 

area, the opacity limitation is 20%. Unconfined blasting with 

abrasives must be done using certified grit. Certified grit is 

defined as follows: 

A.	 Before blasting, the abrasive shall not contain more than 1% 

by weight material passing a ~70 standard sieve. 

B.	 After blasting, the abrasive shall not contain more than 

1.8% by weight materialS microns or smaller. 

This emission point is using confined blasting. 

23.	 R307-1-S, UAC - Emergency episode requirements. This rule
 

applies.
 

24.	 New Source Performance Standards (NSPSl - There is no NSPS for
 

this industrial process.
 

25.	 National Emission Standards for Hazardous Air Pollutants (NESHAPS)
 

- There is no NESHAPS for this industrial process.
 

26.	 National Ambient Air Qualicy Standards (NAAQS) - This source is
 

located in Davis County, which is a nonattainment area for ozone.
 

The Division of Air Quality guidelines do not call for this source
 

to be modeled for any pollutant. The Division has found through
 

experience that, because of the small quantity of em~ssions
 

involved and the conservative predictions made by modeling, a
 

source or emission point of this small size is very unlikely to
 

cause a new violation of the NAAQS.

I. 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 Caterpillar Model No. 3412 DITA emergency diesel 

generator. This generator will serve as a backup for emergency power 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

Particulate 0.09 ton/yr
 

PMIO 0.05
 

S02 O.OB
 

NO. 1. 24
 

CO 0.26

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 generator be proper 

operation and maintenance and 20% opacity.

IV.	 APPLICABILITY OF FEDERAL REGULATIONS AND mAR 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 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 - Continuous program of construction required to 

begin within eighteen months of Approval Order date. If a 

continuous program of construction is not proceeding, the 

Executive Secretary may revoke the Approval Order. 

3.	 R307-1-3.1.8 (A), UAC - Application of best available control 

technology (BACT) required at all emission points. This rule 

applies. 

4.	 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 would produce an emission 

increase greater than or equal to 50.00 tons per year of any 

combination of PM10 , SO~, 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 emission point emits less than 50.00 tons per year 

of combined PM10 , SO~, 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 would produce an emission increase 

greater than or equal to 25.00 tons per year of any combination of 

PM10 , SO~, 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 emission point emits less than 25.00 tons per year of 

combined PM\O' SO~, 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.	 R307-1-3.1.12, UAC - Requirement for installation of lOW-NO. 

burners on all existing sources whenever existing fuel combustion 

burners are replaced, unless the replacement is not physically 

practical or cost effective. The effective date is November 15, 

1990. This rule does not apply to IC engines. 

9.	 R307-1-3.2.1, UAC - Particulate emission limitations for existing 

sources which are located in a nonattainment area. This rule has 

been superseded by the PMIO SIP, except for Weber County. The 

effective date is November 15, 1990. The sources listed in ·Weber 

County are as follows:

not apply. 

10.	 R307-1-3.3.2, UAC - Review requirements for new major sources or 

major modifications 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. 

11.	 R307-1-3.S, UAC - Emission inventory reporting requirements. This 

rule requires any source which emits 2S tons or more per year of 

any pollutant to submit an emission inventory to the Division of 

Air Quality at least every third year or as determined necessary 

by the Executive Secretary. Hill Air Force Base must comply with 

this rule if any specific source emits 25 tons or more per year of 

any pollutant. 

12.	 R307-1-3.6.3, UAC - PSD Increment Consumption - This rule lists 

the allowable PSD increment consumption. Under the PSD rules, the 

entire state has been triggered for TSP, S02' and NO•. The

I. DESCRIPTION OF PROPOSAL 

Hill Air Force Base is planning to replace an 80 KW diesel generator with a 

225 KW diesel generator in Building 565. The new generator is a Caterpillar 

Serial No. 2AJOO536 emergency diesel generator. This generator will serve as 

a backup for emergency power to Weber and Davis County water pumps. This 

generator will be used a maximum of 60 hours per year. 

This generator will use an existing 1,000 gallon above ground diesel storage 

tank for fuel supply. 

This Approval Order will replace an Aproval Order dated September 18, 1980, 

which also included a 15 KW diesel generator in Building 1151 and a 110 gallon 

underground fuel storage tank.

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. and VOC. Also, a natural gas fueled generato~

would be considered BACT 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 

4.2.4-680 
The Engineering Section is recommending that BACT for the generator be proper 

operation and maintenance 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 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 - Continuous program of construction required to 

begin within eighteen months of Approval Order date. If a 

continuous program of construction is not proceeding, the 

Executive Secretary may revoke the Approval Order. 

3.	 R307-1-3.1.B (A), UAC - Application of best available control 

technology (BACT) required at all emission points. This rule 

applies. 

4.	 R307-1-3.1.B (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.B (D), UAC - Enforceable offset of 1.2:1 required for 

new sources or modifications which would produce an emission 

increase greater than or equal to 50.00 tons per year of any 

combination of PM\O' 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 emission point 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 would produce 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, 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 emission point 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 - Requirement for installation of lOW-NO. 

burners on all existing sources whenever existing fuel combustion 

burners are replaced, unless the replacement is not physically 

practical or cost effective. The effective date is November 15, 

1990. This rule does not apply to IC engines. 

9.	 R307-1-3.2.1, UAC - Particulate emission limitations for existing 

sources which are located in a nonattainment area. This rule has 

been superseded by the PMIO S::;:P, except for Weber County. The 

effective date is November 15, 1990. The sources listed in Weber 

County are as follows: 

4 

4.2.4-681
 
A.	 Farmers Grain Coop 

B.	 Fife Rock Products 

C.	 Interpace Corporation 

D.	 Parsons Asphalt Plant 

E.	 Pillsbury Company 

F.	 Teledyne Incinerator 

G.	 Gibbons and Reed Asphalt 

This source is not listed in the SIP. Therefore, this rule does 

not apply. 

10.	 R307-1-3.3.2, UAC - Review requirements for new major sources or 

major modifications 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. 

11.	 R307-1-3.5, UAC - Emission inventory reporting requirements. This 

rule requires any source which emits 25 tons or more per year of 

any pollutant to submit an emission inventory to the Division of 

Air Quality at least every third year or as determined necessary 

by the Executive Secretary. Hill Air Force Base must comply with 

this rule. 

12.	 R307-1-3.6.3, UAC - PSD Increment Consumption - This rule lists 

the allowable PSD increment consumption. Under the PSD rules, the 

entire state has been triggered for TSP, S02' and NO.. The 

allowable increments are as follows: 

TSP 

A.	 Class I areas 

1)	 5 ug/m3 (annual) 

2)	 10 ug/m3 (24 hour) 

B.	 Class II areas

4.2.4-682 
A.	 Class I areas - 2.5 ug/m3 (annual) 

B.	 Class II areas - 25 ug/m3 (annual) 

There are also Class III increments, which do not apply in Utah. 

The above increments apply at all locations, unless the area is 

already nonattainment. The entire increment may not be available 

at all locations due to previously permitted sources consuming 

increment. Modeling analysis is not routinely performed for air 

pollution sources with emissions below the following levels:

13.	 R307-1-3.6.5 (b), UAC - Prevention of significant deterioration 

(PSD) review requirements for new major sources or major 

modifications. This Notice of Intent does not represent a new 

major source or a major modification under PSD rules. Therefore, 

this rule does not apply. 

14.	 R307-1-3.6.6, UAC - Increment violations. This rule requires the 

UAQB to promulgate a plan and implement rules to eliminate any PSD 

increment violations which occur in the state. No known 

violations have yet occurred. This proposed Notice of Intent will 

consume negligible amounts of increment: 

15.	 R307-1-3.8, UAC - Stack height rule. This rule limits the 

creditable height of stacks to that height determined to be good 

engineering practice. The formulas used to determine good 

engineering practice are found in 40 CFR 51.100. A deminimus 

height of 65 meters (213.2 feet) is allowed. Hill Air Force Base 

has no stacks which exceed 65 meters in height. It is in 

compliance with this rule. 

16.	 R307-1-3.11, UAC - Visibility screening analysis requirements. 

This rule requires all new major sources or major modifications to 

undergo a visibility screening analysis to determine visibility 

impact on any mandatory Class I area. This Notice of Intent does 

not represent a new major source or a major modification under 

UACR rules. Therefore, this rule does not apply. 

17.	 R307-1-4.1.2, UAC - 20% opacity limitation at all emission points 

unless a more stringent limitation is required by New Source 

Performance Standards (NSPS) or BACT or National Emission 

6 

4.2.4-683 
Standards for Hazardous Air Pollutants (NESHAPS). In this case,
 

the 20\ opacity limitation applies.
 

18.	 R307-1-4.1.9, UAC - EPA Method 9 to be used for visible emission 

observations. This rule applies. 

19.	 R307-1-4.2.1, UAC - Sulfur content limitations in oil and coal 

used for combustion. This generator burns diesel fuel oil. The 

limitation in the rule is 0.85 pounds of sulfur per 106 BTU heat 

input. BACT is 0.40 based on the AP-42 emission factor. 

20.	 R307-1-4.6, UAC - Continuous Emission Monitoring Systems Program ­

Reporting and technical requirements for continuous emission 

monitoring systems. It covers breakdowns and quarterly reports 

for continuous monitoring systems. Section 4.6.5 states that this 

regulation applies to the following:

VEO's, shall install an opacity monitor on each stack. 

This emission point does not require a CEMS. 

21.	 R307-1-4.7, UAC - Unavoidable breakdown reporting requirements. 

This rule applies. Section 4.7.1 discusses reporting 

requirements. A breakdown for any period longer than 2 hours must 

be reported to the Executive Secretary within 3 hours of the 

beginning of the breakdown, if reasonable, but in no case longer 

than 18 hours after the beginning of the breakdown. A written 

report is required within 7 calendar days. The report shall 

include the estimated quantity of pollutants (total and excess) 

Section 4.7.2 discusses penalties. 

22.	 R307-1-4.9, UAC - Review requirements for volatile organic 

compound (VOC) sources located in a nonattainrnent area for ozone 

constructed in 1980 or earlier. This process is not covered in 

this rule.

I. DESCRIPTION OF PROPOSAL 

Hill Air Force Base is planning to install a 500 KW diesel generator in 

Building 14. 

The new generator is a Caterpillar Model No. 3412 DITA emergency diesel 

generator. This generator will serve as a backup for emergency power to 

airfield runway and beacon lights. This generator will be used a maximum of 

100 hours per year for maintenance. 

A 5,000 gallon above ground diesel storage tank and a 400 gallon day tank will 

also be installed to store fuel for the emergency generator. The emissions 

from the storage tanks are negligible. 

Hill Air Force Base also is planning to relocate a 350 KW generator Cummins 

Model No. NTAB55 from Building 221 to Building 14. This generator will also 

be used a maximum of 100 hours per year. This existing generator does not 

have an Approval Order. 

II . EMISSION SUMMARY

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 emergency generators are proposed to be stand-by generators 

that will only operate in emergency situations and will only be operated for 

approximately 100 hours per year for maintenance. The addition of control 

3 

4.2.4-690 
devices to the generators is not justified. 

The Engineering Section is recommending that BACT for the generators be proper 

operation and maintenance 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 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 - Continuous program of construction required to 

begin within eighteen months of Approval Order date. If a 

continuous program of construction is not proceeding, the 

Executive Secretary may revoke the Approval Order. 

3.	 R307-1-3.1.8 (A), UAC - Application of best available control 

technology (BACT) required at all emission points. This rule 

applies. 

4.	 RJ07-1-3.1.8 (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 would produce an emission 

increase greater than or equal to 50.00 tons per year of any 

combination of PM\o, 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 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 would produce 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, 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 emission point emits less than 25.00 tons per year of 

combined PM10 ' S02' and NO.. Therefore, this rule does not apply. 

7.	 RJ07-1-3.1.9, UAC - Rules for relocation of temporary sources. 

This source is a permanent source. Therefore, this rule does not 

apply. 

8.	 R307-1-3.1.12, UAC - Requirement for installation of lOW-NO, 

burners on all existing sources whenever existing fuel combustion 

burners are replaced, unless the replacement is not physically 

practical or cost effective. The effective date is November 15. 

1990. This rule does not apply to IC engines. 

9.	 R307-1-3.2.1, UAC - Particulate emission limitations for existing 

sources which are located in a nonattainment area. This rule has 

been superseded by the PM10 SIP, except for Weber County. The 

effective date is November 15, 1990. The sources listed in Weber 

4 

4.2.4-691
 
County are as follows: 

A.	 Farmers Grain Coop 

B.	 Fife Rock Products 

C.	 Interpace Corporation 

D.	 Parsons Asphalt Plant 

E.	 Pillsbury Company 

F.	 Teledyne Incinerator 

G.	 Gibbons and Reed Asphalt 

This source is not listed in the SIP. Therefore, this rule does 

not apply. 

10.	 R307-1-3.3.2, UAC - Review requirements for new major sources or 

major modifications 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. 

11.	 R307-1-3.5, UAC - Emission inventory reporting requirements. This 

rule requires any source which emits 25 tons or more per year of 

any pollutant to submit an emission inventory to the Division of 

Air Quality at least every third year or as determined necessary 

by the Executive Secretary. Hill Air Force Base must comply with 

this rule. 

12.	 R307-1-3.6.3, UAC - PSD Increment Consumption - This rule lists 

the allowable PSD increment consumption. Under the PSD rules, the 

entire state has been triggered for TSP, S02' and NO•. The 

allowable increments are as follows: 

TSP 

A.	 Class I areas 

1)	 5 ug/m3 (annual) 

2)	 10 ug/m3 (24 hour) 

B.	 Class II areas 

1)	 19 ug/m3 (annual) 

2)	 37 ug/m3 (24 hour) 

SO, 

A.	 Class I areas 

1)	 2 ug/m3 (annual) 

2)	 5 ug/m3 (24 hour) 

3 )	 25 ug/m3 (3 hour) 

B.	 Class II areas 

1)	 20 ug/m3 (annual) 

2)	 91 ug/m3 (24 hour) 

5 

4.2.4-692 
3)	 5~2 ug/m3 (3 hour) 

A.	 Class I areas - 2.5 ug/m3 (annual) 

B.	 Class II areas - 25 ug/m3 (annual) 

There are also Class III increments, which do not apply in Utah. 

The above increments apply at all locations, unless the area is 

already nonattainment. The entire increment may not be available 

at all locations due to previously permitted sources consuming 

increment. Modeling analysis is not routinely performed for air 

pollution sources with emissions below the following levels: 

Criteria for Screen Modeling 

(Tons per Year) 

Non-Attainment Attainment Areas 

Areas 

SOx 10	 20 

NO, 20	 20 

PM10 5	 5 

TSP 10	 10 

03 5	 5 

CO 25	 50 

VOC 10	 20 

13.	 R307-1-3.6.5 (b), UAC - Prevention of significant deterioration 

(PSD) review requirements for new major sources or major 

modifications. This Notice of Intent does not represent a new 

major source or a major modification under PSD rules. Therefore, 

this rule does not apply. 

14.	 R307-1-3.6.6, UAC - Increment violations. This rule requires the 

UAQB to promulgate a plan and implement rules to eliminate any PSD 

increment violations which occur in the state. No known 

violations have yet occurred. This proposed Notice of Intent will 

consume negligible amounts of increment. 

15.	 R307-1-3.8, UAC - Stack height rule. This rule limits the 

creditable height of stacks to that height determined to be good 

engineering practice. The formulas used to determine good 

engineering practice are found in 40 CFR 51.100. A deminimus 

height of 65 meters (213.2 feet) is allowed. Hill Air Force Base 

has no stacks which exceed 65 meters in height. It is in 

compliance with this rule. 

16.	 R307-1-3.11, UAC - Visibility screening analysis requirements. 

This rule requires all new major sources or major modifications to 

undergo a visibility screening analysis to determine visibility 

impact on any mandatory Class I area. This Notice of Intent does 

not represent a new major source or a major modification under 

UACR rules. Therefore, this rule does not apply. 

6 

4.2.4-693 
17.	 R307-1-4.1.2, UAC - 20% opacity limitation at all emission points -


unless a more stringent limitation is required by New Source 

Performance Standards (NSPS) or BACT or National Emission 

Standards for Hazardous Air Pollutants (NESHAPS). In this case, 

the 20% opacity limitation applies. 

18.	 R307-1-4.1.9, UAC - EPA Method 9 to be used for visible emission 

observations. This rule applies. 

19.	 R307-1-4.2.1, UAC - Sulfur content limitations in oil and coal 

used for combustion. These generators burn diesel fuel oil. The 

limitation in the rule is 0.85 pounds of sulfur per 106 BTU heat 

input. The fuel oil in this case is limited to 0.40 pounds of 

sulfur per 106 BTU heat input based on the AP-42 emission factor. 

20.	 R307-1-4.6, UAC - Continuous Emission Monitoring Systems Program ­

Reporting and technical requirements for continuous emission 

monitoring systems. It covers breakdowns and quarterly reports 

for continuous monitoring systems. Section 4.6.5 states that this 

regulation applies to the following: 

A.	 Sources required to install CEMS as required by the
 

following documents:
 

1) NSPS
 

2) State Implementation Plan
 

3) Approval Order
 

4) Consent Decree
 

5) Administrative Orders and Agreements
 

B.	 Any source that constructs after the promulgation of this 

rule two or more emission points, which may interfere with 

VEO's, shall install an opacity monitor on each stack. -'" 

This emission point does not require a CEMS. 

21.	 R307-1-4.7, UAC - Unavoidable breakdown reporting requirements. 

This rule applies. Section 4.7.1 discusses reporting 

requirements. A breakdown for any period longer than 2 hours must 

be reported to the Executive Secretary within 3 hours of the 

beginning of the breakdown, if reasonable, but in no case longer 

than 18 hours after the beginning of the breakdown. A written 

report is required within 7 calendar days. The report shall 

include the estimated quantity of pollutants (total and excess) 

Section 4.7.2 discusses penalties. 

22.	 R307-1-4.9, UAC - Review requirements for volatile organic 

compound (VOC) sources located in a nonattainment area for ozone 

constructed in 1980 or earlier. This process is not covered in 

this rule. 

23.	 R307-1-5, UAC - Emergency episode requirements. This rule 

applies. 

24.	 New Source Performance Standards (NSPS) - There is no NSPS for 

this industrial process. 

25.	 National Emission Standards for Hazardous Air Pollutants (NESHAPS) 

- There is no NESHAPS for this industrial process. 

26.	 National Ambient Air Quality Standards (NAAQS) - This source is 

located in Davis County, which is a nonattainment area for ozone. 

7 

4.2.4-694 
The Division of Air Quality guidelines do not call for this source 

to be modeled for any pollutant. The Division has found through 

experience that, because of the small quantity of emissions 

involved and the conservative predictions made by modeling, a 

source or emission point of this small size is very unlikely to 

cause a new violation 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 - Any physical or 

operational change to an existing facility which results in an 

increase in the emission rate to the atmosphere of any pollutant 

to which an NSPS standard applies. The following are not by 

themselves considered modifications: 

1) Maintenance, repair, and replacement 

2) An increase in production rate of an existing facility, if 

that increase can be accomplished w~thout a capital 

expenditure on that facility 

3) An increase in the hours of operation 

4) Use of an alternative fuel or raw material if, prior to the 

date any standard under this part becomes applicable to that 

source type, as provided by 60.1, the existing facility was 

designed to accommodate that alternative use 

5) The addition or use of any system or device whose primary 

function is the reduction of air pollutants 

6) Relocation or change in ownership 

Also see Section 1.92, which is the State's definition. It is a 

planned increase in emissions. This Notice of Intent is a 

modification. 

28. 40 CFR 60.15, Definition of Reconstruction - the replacement of 

components of an existing facility to such an extent that: 

1) The fixed capital cost of the new components exceeds 50~ of 

the fixed capital cost that would be required to construct a 

comparable entirely new facility and 

2) It is technologically and economically feasible to meet the 

applicable standards set forth in this part 

This Notice of Intent is not a reconstruction. 

29. R307-1-1.89, Definition of Major Modification - It means any 

physical change in or change in the method of operation of a major 

source that would result in a significant net emission increase of 

any pollutant. A net emissions increase that is significant for 

VOC shall be considered significant for ozone. A phys:cal change 

or change in the method of operation shall not include: 

A. Routine maintenance, repair, or replacement 

B. Use of an alternative fuel or raw material bv reason of an 

order under Section 2a and b of the ESECA of-1974 or by 

reason of a natural gas curtailment plan pursuant to the

Dear Mr Cordner 

In compliance with Section 3.1 of the State Air Conservation Regulations, we submit the attached Notice of Intent to Construct. If 

this office can provide additional information, please feel free to 

contact Jay Gupta at 777-4618.

Emergency Diesel Generators B1dgs 575 & 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 Caterpillar Model 3412 DIT or approved equal together with a 

5,000 gallons above ground diesel storage tank and a 400 gallon day tank 

at Bldg 14 will serve as a back-up for the Airfield Runway and Beacon 

Lights. In addition an existing 350 KW generator will be relocated from 

Bldg 221 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. 

Total KW = 1,450 

Existing K\V = 650 

Incremental KW = 800

3. Air Cleaning Devices: No controls are proposed because these emergency 

power units will be operational only during emergencies and power 

outages. 

4. Emission Points: Each diesel generator will have exhaust approximately 

10 feet above the surrounding ground elevation. 

5. Sample Points: No sampling points are provided 

6. Operating Schedule: Diesel generators will be run only during power 

outage or scheduled maintenance start-ups. 

4.2.4-705
 
Media Blast Booth Bldg 48 

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 blast machine. 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 dust collector. A schematic of the media blast unit is 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. Air Emissions: 

Particulate emissions will be controlled using high efficiency 24 cartridge 

dust collector assembly. The dust collector is 99.9 % efficient to particulate 

size one micron and above and virtually 100 % efficiency for particulate 

two micron and above. 

Exhaust flow rate == 7,000 CFM 

Initial plastic media charge == 1,000 Lbs 

Plastic media carryover or breakdown, per vendor assume @ 5% == 50 Lbs 

Debris and dust carryover, assume @ 1% == 10 Lbs 

At 99.9% efficiency, dust emission rate == 0.01 Lb/min == 0.01 gr/SCF 

Assuming 3-4 hr. per shift operation, 5 days/wk, 52 wks/yr, 

Total emissions = 0.0IX60Xl,040/2,000 == 0.31 Ton/yr 

3. Air Cleaning Devices: Particulate emissions will be controlled usmg high 

efficiency 24 cartridge dust collector assembly. 

4. Emission Points: Emission will be from discharge side of the 1D fan. 

Discharge volume will be 7,000 CFM. 

4.2.4-706 
5. Sample Points: No sampling points are provided 

6. Operating Schedule: This facility will normally be operated about 3-4 

hours an eight-hour shift, 5 days/wk, 52 wks/yr. Depending upon work 

load two shift operation may be necessary.

Emergency Diesel Generator Bldg 565 

1. Project Description: 

An existing 80 KW generator approved under an Approval Order dated 18 

Sept. 1980 is replaced with a Caterpillar Serial 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 of air 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 power unit, this will be in 

operation only during power outage and· for periodic maintenance startups. For units under 250 KW, we run them only for an hour per month to 

ensure their availability in the event of power 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 Emission	 Factors. 

Total KW = 225 

Existing KW = 80 

Incremental KW = 145
