7 _______________________________________________________________________________

8 BACKGROUND

9 1. Respondent submitted Notice of Construction (NOC) Number CL-1410 dated February 16, 

10 1999 to the Southwest Clean Air Agency (SWCAA) for approval of a revision to Order of 

11 Approval 93-1521. Order of Approval 93-1521 was written in response to NOC Number 

12 CL-968, dated March 5, 1993, for approval of previously unpermitted existing facilities for 

13 hard chrome plating operations located at 4221 NE St. Johns Blvd., Units A, G, and H, 

14 Vancouver, Clark County, Washington. The current facility is operated solely out of Units 

15 G and H. The operations in Unit A changed ownership on March 1, 1995 and became 

16 Industrial Finishers, Inc. Effective January 31, 1997 Industrial Finishers, Inc. shut down 

17 permanently.

18 2. Respondent requests the following changes be made to Order of Approval 93-1521:

19 a. Doors to the process area be allowed to remain open during production. Respondent 

20 will install a 2,000 cfm fan to discharge room air from the production area for 

21 cooling; and

22 b. Reduce the foam suppressant monitoring frequency from every 1 hour to the 

23 schedule required by the federal National Emission Standard for Chromium 
Page 2 SWCAA 93-1521R1

1 Emissions from Hard and Decorative Chromium Electroplating and Chromium 

2 Anodizing Tanks.

3 3. Information contained in NOC CL-968 and modified with information from NOC CL-1410 

4 and subsequent site visits indicated that:

5 a. The facility has been in operation since July 1982;

6 b. The chromic acid tanks are used for industrial hard chrome plating of primarily 

7 hydraulic parts in a slow plating, low amperage process;

8 c. Eight plating tanks of various sizes are located in two contiguous units of the 

9 complex at 4221 NE St. Johns Blvd. Six tanks with a total surface area of 44 square 

feet (ft2) are located in Unit G and two tanks also totaling 44 ft210 are in Unit H; these 

11 units are adjacent and connected by a common doorway;

12 d. Control of hexavalent chromium emissions consists of the use of "FOAM-LOK L" 

13 mist suppressant in conjunction with plastic tank covers. Control efficiency relative 

14 to uncontrolled emissions for this product has been shown to range from 95 to 99 

15 percent;

16 e. Past emissions from the operation have been fugitive in nature. Potential emission 

17 points from Unit G, consist of a filtered fan port at the back of the shop 

18 approximately 10 feet above the floor, the office door, and the shop bay door. In 

19 Unit H, emissions can occur from a fire door at the rear of the shop, a wastewater 

20 boil-off vent, and the shop bay door. On warm days, the shop doors have been 

21 opened for increased ventilation and cooling except during plating operations, 

22 resulting in fugitive emissions; and
Page 3 SWCAA 93-1521R1

1 f. Crown Plating, Inc. uses a solvent called "Brake Wash" from Zep Manufacturing 

2 Company that contains isopropyl alcohol and methanol to clean metal parts prior to 

3 electroplating.

4 4. Information contained in NOC CL-1410 and supplemented with information from phone 

5 discussions with Respondent indicated that:

6 a. The proposed room venting system will discharge 2,000 cfm of room air through an 

7 18 inch diameter stack at a height of approximately 25’ above ground level. The 

8 room air intake for the ventilation system will draw air through a 24” by 24” filtered 

9 port approximately 10 feet above the shop floor at the rear of Unit G; and

10 b. Ribbons or equivalent “telltales” will be installed at the roll up door openings to 

11 monitor airflow through the doors and assure that all air movement is into the 

12 facility.

13 5. Respondent provided a Material Safety Data Sheet (MSDS) for chromic acid that indicates 

14 hexavalent chromium is present at the facility. Hexavalent chromium is a Class A toxic air 

15 pollutant listed in Washington Administrative Code (WAC) 173-460, "Controls for New 

16 Sources of Toxic Air Pollutants". No small quantity emission rate exists for chromium due 

17 to its extremely low Acceptable Source Impact Level (ASIL) of 0.000083 micrograms per 

cubic meter (g/m318 ). Respondent also provided a MSDS for Brake Wash, which contains 

19 isopropyl alcohol and methanol, both of which are listed as Class B toxic air pollutants in 

20 WAC 173-460.

21 6. A source test was performed by Respondent using a temporary room exhaust system on 

22 December 22, 1998 to demonstrate compliance with the federal hexavalent chromium 

23 National Emission Standards for Hazardous Air Pollutants. The proposed room ventilation 

24 system will exhaust the same volume of air as the temporary system. During the source test, 
Page 4 SWCAA 93-1521R1

1 total chrome emission rates were measured at 20.2 milligrams (mg) per 1,000 ampere-hours 

2 and 0.0027 mg per dry standard cubic meter (dscm) of exhaust gas. These emission rates 

3 are well within the federal emission limit (0.03 mg/dscm) and previously permitted emission 

4 limits for hexavalent chromium.

5 7. Respondent further certifies that:

6 a. Chromium emissions can be reduced by the approved control efficiency of 98 

7 percent through effective use of "FOAM-LOK L" mist suppressant;

8 b. Future operations at the chrome plating facility will continue to employ slow plating, 

9 low amperage processes;

10 c. All airflow through windows and doors will be directed into the facility by the room 

11 air discharge system;

12 d. The equipment and systems as herein described are acceptable to other agencies 

13 with jurisdiction; and

14 e. No other emission sources, activities, or points of atmospheric discharge or 

15 contemporaneous emission increases are being proposed for installation at this time.

16 APPLICABLE REGULATIONS

17 8. Regulations have been established for the control of air pollutants to the ambient air. 

18 Regulations applicable to the proposed facility which have been used to evaluate the 

19 acceptability of the proposed facility and establish emission limits and control

13 REGULATORY FINDINGS

14 9. The use of “FOAM-LOK L” mist suppressant foam made by Enthone-OMI, Inc. has been 

15 determined to meet the requirements of BACT and T-BACT for the kinds and amounts of 

16 air contaminants emitted from this hard chromium electroplating facility. This product has a 

17 reduction efficiency of 98 percent from uncontrolled emissions when used in accordance 

18 with the manufacturer's directions. The life of the foam blanket is governed by the reaction 

19 time with the chromic acid in the tank and not by the quantity of foam added. Chromium 

20 tank temperature and concentration, tank surface area, electrical current applied, and foam 

21 loss from dragout determine the operating longevity of the foam. A foam blanket of 1 to 2 

22 inches thick is sufficient for control at the certified level according to the manufacturer.
Page 8 SWCAA 93-1521R1

1 10. Source testing contracted by Respondent indicates that the addition of a room air exhaust 

2 system will not cause a violation of the emission limits specified in Order of Approval 93-

3 1521.

4 11. The chrome plating facility, as proposed in NOC CL-1410, if properly installed and 

5 maintained, can be operated without causing a violation of the applicable emission standards 

6 which include the limits established under SWCAA General Regulations for Air Pollution 

7 Sources Sections 400-040 "General Standards for Maximum Emissions" and 400-060 

8 "Emission Standards for General Process Units."
