Percent by weight ofall volatile organic compound potential and hazardous air pollutantpotential foreach individual material listed in A. The percent by weight ofthe volatile and hazardous airpollutant potentials can be obtained from the
. manufacturers' MSDSs. The owner/operatorcan obtain MSDS data from the manufacturers ofthe materials and retain the information on-site. D. Amount and location ofmaterials containing VOCs and HAPs used on a monthly basis and summed for every location and for the entire plant each month. E. To calculate the above potentials containedin the material listed in D use the following procedure: 

## voc

# =(% volatile by Weight) x (Density Ib) x (Gal Consumecj) x (.l...lm1) (100) (gal) (2.000 lb) F. The amount ofvolatile organic content potential (potential airemissions) and hazardous airpollutant potential (potential airemissions) in pounds contained in materials deposited as solid or hazardous waste for the month shall be quantified and subtracted from the quantities calculated above. This is done to allow 4.2.4-65DAQE-1134-95 PageS 

## -. quantification by the source ofthe total VOCs and HAPs emissions. (The assumption is that all the two above potentials ofthe materials applied to :.l product evaporate and are therefore considered emissions). G. Records ofconsumption ofVOCs and HA.;s shall be kept for all periods
. hen the plant is in operation. Records ofconsumption shall be maoe availab;
. to the executive secretary upon request. and shall include a period oftwo years cnding with the date ofthe request. 10. All HAPs are subject to the annual Operating Permit Program ifone ofthe following conditions is met: A. The emissions ofanyone ofthe 189 HAPs listed in the 1990 Clean Air Act is over ten (10) tons/yr B. The emissions ofany combination ofthese HAPs are over 25 tons/yr 11. This source is a major Title V source needing an Operating Permit. It is required to pay an annual emission fee upon stan-up [or ifan existing facility, upon issuance ofthis AO. The fee will be based on calculated annual emissions listed at the end ofthis AD. This fee is valid until inventory data for one year are available for the source. The owner or operator ofthis source will be billed upon start-up for all emissions that are considered "chargeable" as ofthat date.

### 4.2.4-81 Hill AFB Chem Mill Line Engineering Review September 13. 1995 Page 2Abstract Hili Air Force Base (APB) is requesting approval to move and replace their existing Chemical Miiiing Process Line (Chem Miii Line!. The current Chem Miii Line is a grandfathered source and needs to be relocatedfrom Building 265 to Building 238. A water based maskant wiii replace the existing solvent based maskant that is currently being used. This new maskant wiii result in the VOC emissions being reducedfrom 11.9 to 0.38 tons per year. The 5odium Hydroxide emissions wiii remain at 0.29 tons per year and the lsoprep emissions wiii remain at 0.44 tons per year. Hill APB is a major source that is located in Davis County which is a Nonattainment Areafor PMIO and Ozone.


### I. DESCRIPTION OF PROPOSAL Hill Air Force Base (AFB) is requesting approval to move and replace their existing Chemical Milling Process Line (Chern Mill Line). The current Chern Mill Line is a grandfathered source and needs to be relocared from Building 265 to Building 238. A water based maskant will replace the existing solvent based maskant is presently being used. This new maskant will result in the VOC emissions being reduced from 11.9 tons to 0.11 tons per year.
II. EMISSION SUMMARY The emissions from the Hill Air Force Base Chemical Milling Process Line will be as follows: Current Emissions Emission Changes Total Emissions Pollutant tons/vear tons/year tons/year VOC 11.85 , -11.47 " 0.38 NaOH 0.29 0.0
. . . . . . . . . . . .. 0.29 Isoprep
. . . . . . . . . . . . . . . . 0.44 0.0
. . . . . . . . . . . .. 0.44 The VOC emissions come from the warer based maskant. and 0.4% of the maskant is Styrene (0.4% x 0.11 tpy 

# =0.0004 tpy), 4% of the maskant is Toluene (4% x 0.11 tpy = 0.0044 tpy).
III. BEST AVAILABLE CONTROL TECHNOLOGY (BACT) ANALYSIS Presently a VOC maskant is being used on the Chemical Milling Process Line in Building 265. When the 01emical Milling Line is moved to Building 238 a new water based maskant will be used. This will result in a 99% reduction in VOC emissions. The New Source Review section recommends that the new Chemical Milling Process Line be accepted as BACf with a 10% opacity limit
IV. APPLICABILITY OF FEDERAL REGULATIONS AND UTAH ADMINISTRATIVE CODES fUAC} TItis Notice of Intent is for grandfathered 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.L UAC

- Notice of Intent required for a modified source. This rule applies. A Notice of Intent is required for the new Chemical Milling Process Line.

BACT for these sources should be evaluated in light of the RACf requirements that have been established by UACR 14. BACT in an attairunent area may be determined to be less stringent than the RACf requirements established in rule 14 or a published Control Techniques Guidance document (which apply to a Nonanairunent area) however. a detailed BACT analysis should be conducted by the source to justify a less stringent control measure in an anairunent area. This source is located in Davis County. Therefore. this rule applies to this source. 27. 40 CFR. Pan 60

- National Ambient Air Quality Standards (NAAQS)

- This source is located in Davis Countv, which is a Nonanairunent 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 a source or emission point of this small size is very unlikely to cause a new violation ofthe NAAQS. This is because of the small quantity of emissions involved and the conservative predictions made by modeling. However. it will make a small contribution to the existing violation for ozone of the NAAQS. For VOC emissions. there is no model that can predict an ozone impact directly from VOC emissions. However. since VOCs are precursors to ozone formation. this new source will contribute to the existing exceedances ofthe ozone standard in Davis County. The amount ofthat contribution has not been decided. The ozone Nonattairunent area of Davis and Salt Lake Counties must show reasonable further progress toward attairunent of the standard. This source. along with all other VOC sources having emissions above ten tons per year. may have to apply more controls to lower the VOC emissions. This would be a SIP change action. 30. 40 CFR 60.14. Definition of Modification

. PO Box 144820

Salt Lake City, UT 84114-4820 RE: Relocation of the Chemical Milling Process Line from Building 265 into Building 238 Dear Mr Menlove This letter supersedes the one dated 3 March 1995 in which we requested an Experimental Approval Order to test a new maskant in the chemical milling process, and to relocate the process to Building 238. The current chemical milling operation is a grandfathered source and must be relocated from its present location in Building 265 into Building 238. However, there is no need for on-site testing of the altemative maskant material. Process engineers have investigated the use of the new material at other locations and based upon this information have determined it will meet their needs. This letter is to**serv~ ~~Q!~?**  of IntenUor an**Approva~r** to use the new maSKant material and relocate the process to Building 238. A detailed emissions estimate is provided in attachment 1. This estimate shows that the new maskant will reduce VOC emissions, from this process, by more than 11.5 tons. The estimated annual VOC emissions from the new process would be approximately 223 Ibs per year. Based upon this analysis the new process would qualify as an insignificant source under Title V. The new maskant exceeds standards established in the proposed 40 CFR 63.747, National Emission Standards for Hazardous Air Pollutants, Aerospace Manufacturing and Rework, which specifies VOC content for compliant maskants must be less than 1.3 Ibslgal. Your prompt response to this request would be greatly appreciated, so we may start up this new process as soon as possible. The original 3 March 1995 letter was assigned to Mr Nando Meli. If you have any questions regarding this matter please contact Mike Graziano at

### A. Roberts 3 Mar 1995 Executive Secretary Division of Air Quality 1950 West North Temple PO Box 144820 Salt Lake City, UT 84114-4820 RE: Notice of Intent to Setup a Chemical Milling Process Line in Building 238 Dear Mr Roberts This letter is to serve as a Notice of Intent to setup a chemical milling process line in Building 238. The current chemical milling operation is a grandfathered source located in Building 265 which must be relocated. During the first 90 days of operation, we also request approval to test a new water based maskant in the process. If the results of this test are favorable, we will use the water based maskant in place of the solvent based maskant currently being used in Building 265. However, if the test is not successful, we request approval to continue using the present solvent based maskant at the new location until a lower

## vac maskant can be found that meets the performance requirements. A report of the results comparing the two maskants will be made available upon completion of the test period. The proposed project requires the installation of five 2000 gal dip tanks in Building 238, four of which will be exhausted to the outside (see Attachment 1, detailed process description and emissions estimate). The only difference between the two candidate processes is the type of maskant used. All equipment and other materials are the same.

4.2.4-117

### Your prompt response to this matter would be greatly appreciated as we would like to begin testing the new maskant as soon as possible. Please contact Michael Graziano at 777-0359 if you require additional information. Sincerely I

Install five new process tanks in building 238 (Proposed layout attachment 2) Tank #1 Maskant Dip, exhausted to outside Tank #2 Hot Water Dip, exhausted to outside Tank #3 Isoprep, exhausted to outside Tank #4 Water Spray Rinse Tank #5 Sodium Hydroxide, exhausted to outside All dip tanks are 2000 gallons. Slotted ventilation systems across the top of tanks 1, 2, and 3 will be manifolded together and exhausted through a 38" duct 60' above ground level. The slotted ventilation system across the top of tank 5 will be exhausted through a 24" duct 60' above ground level. B. The general process for each part is as follows; 1. Dip in Sodium Hydroxide, tank #5, for 30 seconds; flash cleaning. 2. Dip in Hot Rinse, tank #2. 3. Dip in Isoprep, tank #3; desmutting. 4. Spray Rinse in tank #4 5. Hang Dry 6. Dip in Maskant, tank #1. 7. Hang Dry 24 hours 8. Use template and cut away maskant from area to be milled. 9. Dip in Sodium Hydroxide tank #5, exposed metal areas are milled at 0.001 inch per minute. 10. Dip in Hot Rinse tank #2. 11. Dip in Isoprep tank #3, for cleaning. 12. Spray Rinse in tank #4. 13. Repeat steps 8-12 as needed to mill various areas to desired depths. (Note: The process and materials are the same for both regardless of the maskant used.) C.

### DIRECTIONS 

### FOR USE: 1. Precleaning: For optimum uniformity in adhesion and performance the parts to be masked must be free at oil, grease, dirt or corrosion. Your TURCO Territory Manager can recommend suitable TURCO cleaners based on specifications and proauc:lon needs. 2. MixIng: To assure reproducible reSUlts In application and performance of the TURCOFORM MASK 522. adequate mixing of the solution is very important prior 'to and during use. caution must be exercised 

### to prevent air from being dra'l'm into the mask by the mixing action. Since some solvent is lost during use due to evaporation. periodic additIons of thinner are required. TIle amount of thinner**requir~d** is based on viscosity measurements. A #5 Zahn cup viscometer may be used to measure and adjust the maskant to the desired operating viscosity. 4? 4_1?1I I
