PLANT NAME High Lustre Metal Finishing

APPLICATION NUMBER 19119

PLANT NUMBER 7111

DATE 11-13-2008

1. BACKGROUND

On October 24, 2007, a major revision to the Airborne Toxic Control Measure (ATCM) for 

Chromium Plating and Chromic Acid Anodizing became law in California. As a result, the permit 

conditions for the District chrome platers (there are no chromic acid anodizers operating in the 

BAAQMD) need to be revised to address these changes. Following is a listing of the sources 

involved and the current and revised condition numbers. The ATCM can be found at the following 

website: http://www.arb.ca.gov/toxics/atcm/chroatcm.pdf

In Section

93102.8(a)

n/a n/a

District regulations allow the APCO to make changes of permit conditions, based on certain 

criteria, enumerated in Reg 2-1-403:

Permit Conditions: Except as to permit applications reviewed in accordance with

Section 2-1-311, the APCO may impose any permit condition that he deems

reasonably necessary to insure compliance with federal or California law or District

regulations. For any permit application which was reviewed as a ministerial project in

accordance with Section 2-1-311, the APCO shall only impose permit conditions as

set forth in the District's Permit Handbook for the type of source being permitted. The

APCO may require the installation of devices for measurement or analysis of source

emissions or ground-level concentrations of air contaminants.

The proposed condition changes are to ensure compliance with the Chrome Plating ATCM, 

revised 10-24-2007.

2. EMISSION CALCULATIONS

This facility is located more than 330 feet from the nearest sensitive receptor. Also the chrome 

plating tank is currently permitted to operate up to 45,500 amp-hr/yr. The ATCM allows facilities 

to operate at throughputs up to 50,000 amp-hr/yr using only a surfactant, if the facility is located 

more than 330 feet from the nearest sensitive receptor. The permitted throughput level will not be 

increased though, since that would constitute an emission increase in this case. Therefore, we do 

not expect any change in the emission levels.

Net Difference 0 0 0

3. CEQA

Since the change of conditions will result in no change in the permitted emission levels, this

application is exempt from CEQA review per Reg 2-1-312.1.

4. BEST AVAILABLE CONTROL TECHNOLOGY

There is no change in emission levels, therefore BACT is not applicable.

5. EXEMPTIONS

There are no applicable exemptions.

6. OFFSETS

Offsets are not applicable, since emissions remain the same, therefore no offset triggers are 

exceeded.

7. TOXIC EVALUATION

Permitted emission levels remain static, therefore no toxic evaluation is required. Previous toxic 

risk evaluations have been conducted showing there are no significant risks to any member of the 

public from these operations. A previous risk evaluation showed risks to the MEI were less than 

10 in a million. Since there is no change in emissions, we do not expect risk levels to change.

8. STATEMENT OF COMPLIANCE

The purpose of revising the permit conditions is to ensure that the facility complies with the newly 

revised air toxic control measure.

9. CONDITIONS

The previous version of Condition 6595 is presented in this application, as is the revised Condition 

6595.

10. RECOMMENDATIONS

Issue a Change of Condition letter for the aforementioned sources, subject to the revised 

Condition 6595.

 The total annual combined throughput at source S-1 shall

 not exceed 45,500 amp-hrs in any consecutive twelve month

 period. 

 2) Amp-hours of operation 

 To comply with the above condition, High Luster Metal

 Finishing shall keep and maintain monthly records of

 current applied to this source integrated over time, in

 units of ampere-hours. Ampere-hour records to be

 monitored using non-resettable amp-hour meter. Ampere-

 hour meter to be installed in a manner so as to prevent

 the operation of the bath rectifier without the

 simultaneous operation of the ampere-hour meter. 

 3) Abatement- Plating Bath Surface Tension 

 Source S-1 shall not be operated unless the plating bath

 is operated with McGean Rohco Dis-mist FCS-1 wetting-

 agent additive or equivalent with bath surface tension

 not to exceed 45 dyne/cm. 

 4) Monitoring of Surface Tension - Frequency 

 To demonstrate compliance with condition 3, above,

 surface tension of source S-1 shall be monitored at a

 frequency of at least one time every 4,000 amp-hours of

 bath operation. 

 If after 40,000 amp-hours of rectifier operation, the

 surface tension monitoring results indicate no

 exceedances of the maximum surface tension standard

 identified in Condition 3, above, the monitoring

 frequency can be reduced to "at least one time every

 8,000 amp-hours of bath operation." 

 If further surface tension monitoring results indicate no

 exceedances of the maximum surface tension standard

 identified in Condition 3, above, after an additional

 40,000 amp-hours of operation, the monitoring frequency

 can be further reduced to "at least one time every 40,000

 amp-hours of bath operation". 

 5) Surface Tension Monitoring - Testing Methods 

 Surface tension testing shall be conducted as specified

 in EPA Method 306-B by the use of a stalagmometer or

 preciser tensiometer as directed by manufacturers

 instructions. Alternate test methods may also be used if

 the method has been appropriately validated using EPA

 Method 301, Appendix A, 40 CFR Part 63. 

 6) Initial Performance Testing - Required Records

 8) Reporting 

 High Luster Metal Finishing shall provide the BAAQMD with

 the following reports at the specified frequencies

 identified as follows: 

 a) Notification of initial compliance status: Within 90

 days of compliance performance test.

 b) Annual total throughput of chrome plating operation in

 d) Dragout shall be minimized by: 

 i. handling the plated parts so that chromic acid

 is not dripped outside the tank, and

 ii. installing splash guards at the tank to

 minimize overspray and to ensure that chrome

solution is returned to the tank. 

 e) Surfaces within the chrome storage area and the

 walkways and other areas potentially contaminated

 with hexavalent chrome, shall be cleaned at least

 one time every seven days by either HEPA vacuuming,

 damp cloth hand wiping, wet mopping, use of non-

 toxic dust suppressants or any other District-

 approved method. 

 f) Buffing, grinding or polishing areas shall be

 separated from the chrome plating operation by a

 physical barrier, which may include, but is not

 limited to vertical plastic strip curtains.

 any of the above housekeeping activities shall be

 stored, disposed of, recovered, or recycled using

 practices that minimize fugitive dust. 

 5. Monitoring 

 a) Each rectifier shall be hard-wired to a single non-

 resettable meter which records ampere-hours

 continuously during rectifier operation. Each

 ampere-hour meter shall be installed and maintained

 per manufacturer's specifications. The

 owner/operator shall record the total ampere-hours

 used during each month.

 [Basis: 93102.9(a), 93102.12(c)(1)]

 frequency may be automatically extended to one time

 per calendar week of plating tank operation. If an

 exceedance occurs, the measurement frequency shall

 return to daily for 20 operating days, and weekly

 thereafter. [Basis: 93102.9(d), 93102.12(c)(4)]
