_______________________________________________________________________________ 7 **BACKGROUND** 8 1. Respondent submitted Notice of Construction (NOC) Number CL
- 1410 dated February 16, 9 1999 to the Southwest Clean Air Agency (SWCAA) for a pproval of a revision to Order of 10 Approval 93
- 1521. Order of Approval 93
- 1521 was written in response to NOC Number 11 CL
- 968, dated March 5, 1993, for approval of previously u npermitted existing facilities for 12 hard chrome plating operations located at 4221 NE St. Johns Blvd., Units A, G, and H, 13 Vancouver, Clark County, Washington. The current facility i s operated solely

out of Units 14 G and H. The operations in Unit A changed ownership on March 1, 1995 and became 15 Industrial Finishers, Inc. Effective January 31, 1997 Industrial Finishers, Inc. shut down 16 permanently
. 17 2. Respondent requests the following changes be made to Order of Approval 93
- 1521: 18 a. Doors to the process area be allowed to remain open during production. Respondent 19 will install a 2,000 cfm f an to discharge room air from the production area for 20 cooling; and 21 b. Reduce the foam suppressant monitoring frequency f rom every 1 hour to the 22 schedule required by t he federal National Emission Standard for Chromium 23Page 2 SWCAA 93
- 1521R1 Emissions from Hard and Decorative Chromium Electroplating and Chromium 1 Anodizing Tanks. 2 3. Information contained in NOC CL
- 968 and modified with information from NOC CL
- 1410 3 and subsequent site visits indicated that: 4 a. The facility has been in operation since July 1982; 5 b. The chromic acid tanks are used for industrial hard chrome plating of primarily 6 hy

draulic parts in a slow plating, low amperage process; 7 c. Eight plating tanks of various sizes are located in two contiguous units of the 8 complex at 4221 NE St. Johns Blvd. Six tanks with a total surface area of 44 square 9 feet (ft2) are located in Unit G and two tanks also totaling 44 ft 2 are in Unit H; these 10 units are adjacent and connected by a common doorway; 11 d. Control of hexavalent chromium emissions consists of the use of "FOAM
-LOK L" 12 mist suppressant in conjunction with plastic tank covers. Control efficiency relative 13 to uncontrolled emissions for this product has been shown to range from 95 to 99 14 percent; 15 e. Past emissions from the operation have been fugitive in nature. P otential emission 16 points from Unit G, consist of a filtered fan port at the back of the shop 17 approximately 1 0 feet above the floor, the office door, and the shop bay door. I n 18 Unit H, emissions can occur from a fire door at the rear of the shop, a wastewater 19 boil
-off vent, and the shop bay door. On warm days, the shop doors have been 20 opened for increased ventilation and cooling except during plating operations, 21 resulting in fugitive emissions; and 22Page 3 SWCAA 93
- 1521R1

f. Crown Plating, Inc. uses a solvent called "Brake Wash" from Zep Manufacturing 1 Company t hat contains isopropy

l alcohol and methanol to clean metal parts prior to 2 electroplating. 3 4. Information contained in NOC CL
- 1410 and supplemented with information from phone 4 discussions with Respondent indicated that: 5 a. The proposed room venting system will discharge 2,000 cfm of room air through an 6 18 inch diameter stack at a height of approximately 25’ above ground level. The 7 room air intake for the ventilation system will draw air through a 24” by 24” filtered 8 port approxima tely 10 feet above the shop floor at the rear of Unit G; and 9 b. Ribbons or equivalent “telltales” will be installed at the roll up door openings to 10 monitor airflow through the doors and assure that all air movement is into the 11 facility
. 12 5. Respondent provided a Material Safety D ata Sheet (MSDS) for chromic acid that indicates 13 hexavalent chromium is present at the facility
. Hexavalent chromium is a Class A toxic air 14 pollutant listed in Washington Administrative Code (WAC) 173
-460, "Controls for New 15 Sources of Toxic Air Pollutants". No small quantity emission rate exists for chromium due 16 to its extremely low Acceptable Source Im pact Level (ASIL) of 0.000083 micrograms per 17 cubic meter (  g/m3 ). Respondent also provided a MSDS for Brake Wash, which contains 18 i sopropy

l alcohol and methanol, both of which are listed as Class B toxic air pollutants in 19 WAC 173
-460. 20 6. A source test was performed by Respondent using a temporary room exhaust system on 21 December 22, 1998 to demonstrate compliance with the federal hexavalent chromium 22 National Emission Standards for Hazardous Air Pollutants. The proposed room ventilation 23 system will exhaust the same volume of air as the temporary system. During the source test, 24Page 4 SWCAA 93
- 1521R1

total chrome emission rates were measured at 20.2 milligrams (mg) per 1,000 ampere-hours 1 and 0.0027 mg per dry standard cubic meter (dscm) of exhaust gas. These emission rates 2 are well within the federal emission limit (0.03 mg/dscm) and previously permitted emission 3 limits for hexavalent chromium. 4 7. Respondent further certifies that: 5 a. Chromium emissions can be reduced by t he approved control efficiency of 98 6 percent through effective use of "FOAM
-LOK L" mist suppressant; 7 b. Future operations at the chrome plating facility will continue to employ

slow plating, 8 low amperage processes; 9 c. All airflow through windows and doors will be directed into the facility by the room 10 air discharge system; 11 d. The equipment and systems as herein described are acceptable to other agencies 12 with jurisdiction; and 13 e. No other emission sources, activities, or points of atmospheric discharge or 14 contemporaneous emission increases are being proposed for installation at this time. 15 **APPLICABLE REGULATIONS** 16 8. Regulations have been established for the control of air pollutants to the ambient air. 17 Regulations applicable to the proposed facility which have been used to evaluate the 18 acceptability of the proposed facility and establish emission limits and control 19 requirements include, but are not limited to, the following regulations, code s, or 20 requirements. These items establish maximum emissions limits that could be allowed 21 and are not to be exceeded for new or existing facilities: 22 a. Title 40 Code of Federal Regulations (CFR) 63.340 et seq. (Subpart N) "National 23 Emission Standards for Chromium Emissions form Hard and Decorative 24Page 5 SWCAA 93
- 1521R1 Chromium Electroplating and Chromium Anodizing Tanks" establishes 1 conditions of operation for each chromium anodizing tank at facilities performing 2 hard chromium electroplating, decorative chromium electroplating, or chromium 3 anodizing. This facility performs hard chromium electroplating and is subject to 4 this regulation. 5 b. Revised Code of Washington (RCW) 70.94.152 requires that no approval to 6 construct or alter an air contaminant source shall be granted unless all known 7 available and reasonable means of emission control are provided and that the 8 operation of such equipment will not aid in the contravention of ambient air quality 9 standards. 10 c. RCW 70.94.152 provides for the inclusion of conditions of operation as are 11 reasonably necessary to assure the maintenance of compliance with the applicable 12 ordinances, resolutions, rules and regulations when issuing an Order of Approval for 13 installation and establishment of an air contaminant source. 14 d. Washington Administrative Code (WAC) 173
-400
- 075 “Emission Standards for 15 Sources Emitting Hazardous Air Pollutants” adopts by reference the federal 16 NESHAP for chromium electroplating. 17 e. WAC 173
-460 "Controls for New Sources of Toxic Air Pollutants" requires Best 18 Availa ble Control Technology for toxic air pollutants (T
-BACT), identification and 19 quantification of emissions of toxic air pollutants and demonstration of protection of 20 human health and safety
. 21 f. WAC 173
-460
- 060 "Control Technology Requirements" requires that facility
-wide 22 uncontrolled hexavalent chromium emissions from plating or anodizing tanks be 23 reduced by at least 95% for facilities emitting 1 kilogram or less of hexavalent 24Page 6 SWCAA 93
- 1521R1 chromium. This facility

emits less than 1 kilogram of hexavalent chromium and is 1 subject to this regulation. 2 g. SWAPCA 400
- 040 "General Standards for Maximum Emissions" requires all new 3 and existing sources and emission units to meet certain performance standards with 4 respect to Reasonably Available Control Technology (RACT), visible emissions, 5 fallout, fugitive emissions, odors, emissions detrimental to persons or property, 6 sulfur dioxide, concealment and masking and fugitive dust. 7 h. SWAPCA 400
- 040(3) "Fugitive Emissions" requires that reasonable precautions 8 shall be taken to preven t the release of air contaminants to the atmosphere. 9 i. SWAPCA 400
- 040(4) "Odors" requires any source which generates odors which 10 unreasonably interfere with any

other property

owner's use and enjoy

ment of their 11 property to use recognized good practice and procedures to reduce these odors to a 12 reasonable minimum. 13 j. SWAPCA 400
-060 "Emission Standards for General Process Units" requires that all 14 new and existing sources not emit particulate matter in excess of 0.1 grains per dry 15 standard cubic foot of exha ust gas. 16 k. SWAPCA 400
- 110 "New Source Review" requires that a Notice of Construction 17 application be filed with SWAPCA prior to the establishment of any new source or 18 emission unit or modification and that an Order of Approval be issued prior to 19 establish ment of the new source or emission unit. 20 l. SWAPCA 400
- 111 "Requirements for Sources in a Maintenance Plan Area" 21 requires that no approval to construct or alter an air contaminant source shall be 22 granted unless it is evidenced that: 23Page 7 SWCAA 93
- 1521R1 1. The equipment or technology is designed and will be installed to operate 1 without causing a violation of the applicable emission standards; 2 2. Emissions will be minimized to the extent that the new source will not 3 exceed emission levels or other requirements provided in t he maintenance 4 plan; 5 3. Best Available Control Technology will be employed for all air 6 contaminants to be emitted by the proposed equipment; 7 4. The proposed equipment will not cause any a mbient air quality

standard to 8 be exceeded; and 9 5. If the propos ed equipment or facility will emit any

toxic air pollutant 10 regulated under WAC 173
-460, the proposed equipment and control 11 measures will meet all the requirements of that Chapter. 12 **REGULATORY FINDINGS** 13 9. The use of “FOAM
-LOK L” mist suppressant foam made by Enthone
- OMI, Inc. has been 14 determined to meet the requirements of BACT and T
-BACT for the kinds and amounts of 15 air contaminants emitted from this hard chromium electroplating facility. This product has a 16 reduction efficiency o f 98 percent from uncontrolled emissions when used in accordance 17 with the manufacturer's directions. The life of the foam blanket is governed by t he reaction 18 time with the chromic acid in the tank and not by t he quantity

o f foam added. Chromium 19 tank temperature and concentration, tank surface area, electrical current applied, and foam 20 loss from dragout determine the operating longevity of the foam. A f oam blanket of 1 to 2 21 inches thick is sufficient for control at the certified level according to the manufacturer. 22Page 8 SWCAA 93
- 1521R1

10. Source testing contracted by Respondent indicates that the addition of a room air exhaust 1 system will not cause a violation of the emission limits specified in Order of Approval 93
- 2 1521. 3 11. The chrome plating facility, as proposed in NOC CL
- 1410, if properly installed and 4 maintained, can be operated without causing a violation of the applicable emission standards 5 which include the limits established under SWCAA General Regulations for Air Pollution 6 Sources Sections 400
- 040 "General Standards for Maximum Emissions" and 400
