§ 93102. Airborne Toxic Control Measure for Chromium Plating and

Chromic Acid Anodizing Facilities.

The Airborne Toxic Control Measure for Chromium Plating and Chromic Acid Anodizing Facilities (ATCM) is contained in sections 93102 through 93102.16. The ATCM is organized as

follows:

Sections 93102 through 93102.3 specify the applicability of the ATCM, exemptions, and definitions. Section 93102.4 sets forth requirements for hexavalent chromium facilities that differ depending on whether a facility is an existing facility, a modified facility, or a new facility. Section 93102.5 sets forth various new requirements that apply to all facilities beginning October 24, 2007 (i.e., all existing, modified, and new facilities). Section 93102.6 contains special provisions that apply only to enclosed hexavalent chromium electroplating facilities and facilities that perform electroplating using a trivalent chromium bath. Sections 93102.7 through 93102.14 contain additional requirements that apply to all facilities, unless an exception is provided in this ATCM. Most of the requirements in sections 93102.7 through 93102.14 have been in effect since 1998. Section 93102.15 sets forth requirements that apply to the manufacture, sale, supply, offer for sale, and use of chromium plating and chromic acid anodizing kits in California. There are nine appendices to the ATCM; these appendices are contained

in section 93102.16.

Changes

1. U.S. EPA, or the implementing agency, in accordance with any delegation of authority to approve alternatives from the U.S. EPA.

2. Minor change to test method means: (1) A modification to a federally enforceable test method that: (i) Does not decrease the stringency of the emission limitation or standard; (ii) Has no national significance (e.g., does not affect implementation of the applicable regulation for other affected sources, does not set a national precedent, and individually does not result in a revision to the test method); and (iii) Is site-specific, made to reflect or accommodate the operational characteristics, physical constraints, or safety concerns of an affected source.42 (2) Examples of minor changes to a test method include, but are not limited to: (i) Field adjustments in a test method's sampling procedure, such as a modified sampling traverse or location to avoid interference from an obstruction in the stack, increasing the sampling time or volume, use of additional impingers for a high moisture situation, accepting particulate emission results for a test run that was conducted with a lower than specified temperature, substitution of a material in the sampling train that has been demonstrated to be more inert for the sample matrix; and (ii) Changes in recovery and analytical techniques such as a change in quality control/quality assurance requirements needed to adjust for analysis of a certain sample matrix.

3. Intermediate change to test method means a within-method modification to a federally enforceable test method involving “proven technology'' (generally accepted by the scientific community as equivalent or better) that is applied on a site-specific basis and that may have the potential to decrease the stringency of the associated emission limitation or standard. Though site-specific, an intermediate change may set a national precedent for a source category and may ultimately result in a revision to the federally enforceable test method. In order to be approved, an intermediate change must be validated according to U.S. EPA Method 301 (40 CFR Part 63, Appendix A) to demonstrate that it provides equal or improved accuracy and precision. Examples of intermediate changes to a test method include, but are not limited to: (1) Modifications to a test method's sampling procedure including substitution of sampling equipment that has been demonstrated for a particular sample matrix, and use of a different impinger absorbing solution; (2) Changes in sample recovery procedures and analytical techniques, such as changes to sample holding times and use of a different analytical finish with proven capability for the analyte of interest; and (3) “Combining'' a federally required method with another proven method for application to processes emitting multiple pollutants.

4. Major change to test method means a modification to a federally enforceable test method that uses “unproven technology or procedures'' (not generally accepted by the scientific community) or is an entirely new method (sometimes necessary whenthe required test method is unsuitable). A major change to a test method may be sitespecific, or may apply to one or more sources or source categories, and will almost always set a national precedent. In order to be approved, a major change must be validated according to EPA Method 301 (40 CFR Part 63, Appendix A). Examples of major changes to a test method include, but are not limited to: (1) Use of an unproven analytical finish; (2) Use of a method developed to fill a test method gap; (3) Use of a new test method developed to apply to a control technology not contemplated in the applicable regulation; and (4) Combining two or more sampling/analytical methods (at least one unproven) into one for application to processes emitting multiple pollutants.

5. Minor change to monitoring means: (1) A modification to federally required monitoring that: (i) Does not decrease the stringency of the compliance and enforcement measures for the relevant standard; (ii) Has no national significance (e.g., does not affect implementation of the applicable regulation for other affected sources, does not set a national precedent, and individually does not result in a revision to the monitoring requirements); and (iii) Is site-specific, made to reflect or accommodate the operational characteristics, physical constraints, or safety concerns of an affected source. (2) Examples of minor changes to monitoring include, but are not limited to: (i) Modifications to a sampling procedure, such as use of an improved sample conditioning system to reduce maintenance requirements; (ii) Increased monitoring frequency; and (iii) Modification of the environmental shelter to moderate temperature fluctuation and thus protect the analytical instrumentation.43 6. Intermediate change to monitoring means a modification to federally required monitoring involving “proven technology'' (generally accepted by the scientific community as equivalent or better) that is applied on a site-specific basis and that may have the potential to decrease the stringency of the associated emission limitation or standard. Though site-specific, an intermediate change may set a national precedent for a source category and may ultimately result in a revision to the federally required monitoring. Examples of intermediate changes to monitoring include, but are not limited to: (1) Use of a continuous emission monitoring system (CEMS) in lieu of a parameter monitoring approach; (2) Decreased frequency for non-continuous parameter monitoring or physical inspections; (3) Changes to quality control requirements for parameter monitoring; and (4) Use of an electronic data reduction system in lieu of manual data reduction.

7. Major change to monitoring means a modification to federally required monitoring that uses “unproven technology or procedures'' (not generally accepted by the scientific community) or is an entirely new method (sometimes necessary when the required monitoring is unsuitable). A major change to monitoring may be site-specific or may apply to one or more source categories and will almost always set a national precedent. Examples of major changes to monitoring include, but are not limited to: (1) Use of a new monitoring approach developed to apply to a control technology not contemplated in the applicable regulation; (2) Use of a predictive emission monitoring system (PEMS) in place of a required continuous emission monitoring system (CEMS); (3) Use of alternative calibration procedures that do not involve calibration gases or test cells; (4) Use of an analytical technology that differs from that specified by a performance specification; (5) Decreased monitoring frequency for a continuous emission monitoring system, continuous opacity monitoring system, predictive emission monitoring system, or continuous parameter monitoring system; (6) Decreased monitoring frequency for a leak detection and repair program; and (7) Use of alternative averaging times for reporting purposes.

8. Minor change to recordkeeping/reporting means: (1) A modification to federally required recordkeeping or reporting that: (i) Does not decrease the stringency of the compliance and enforcement measures for the relevant standards; (ii) Has no national significance (e.g., does not affect implementation of the applicable regulation for other affected sources, does not set a national precedent, and individually doesnot result in a revision to the recordkeeping or reporting requirement); and (iii) Is sitespecific. (2) Examples of minor changes to recordkeeping or reporting include, but are not limited to: (i) Changes to recordkeeping necessitated by alternatives to monitoring; (ii) Increased frequency of recordkeeping or reporting, or increased record retention periods; (iii) Increased reliability in the form of recording monitoring data, e.g., electronic or automatic recording as opposed to manual recording of monitoring data; (iv) Changes related to compliance extensions granted pursuant to 40 CFR Part 63 Section 63.6(i); (v) Changes to recordkeeping for good cause shown for a fixed short duration, e.g., facility shutdown; (vi) changes to recordkeeping or reporting that is clearly redundant with equivalent recordkeeping/reporting requirements; and (vii) Decreases in the frequency of reporting for area sources to no less than once a year for good cause shown, or for major sources to no less than twice a year as required by title V, for good cause shown.

9. Major change to recordkeeping/reporting means: (1) A modification to federally required recordkeeping or reporting that: (i) May decrease the stringency of the required compliance and enforcement measures for the relevant standards; (ii) May have national significance (e.g., might affect implementation of the applicable regulation for other affected sources, might set a national precedent); or (iii) Is not site-specific. (2) Examples of major changes to recordkeeping and reporting include, but are not limited to: (i) Decreases in the record retention for all records; (ii) Waiver44 of all or most recordkeeping or reporting requirements; (iii) Major changes to the contents of reports; or (iv) Decreases in the reliability of recordkeeping or reporting (e.g., manual recording of monitoring data instead of required automated or electronic recording, or paper reports where electronic reporting may have been required).

Appendix 5 - Smoke Test for Chrome Tank Covers

SMOKE TEST TO VERIFY THE SEAL INTEGRITY OF COVERS DESIGNED

TO REDUCE CHROMIUM EMISSIONS FROM ELECTROPLATING AND

ANODIZING TANKS

1. Applicability and Principle

2. Applicability. This alternative method is applicable to all hard chromium

electroplating and anodizing operations where a chrome tank cover is used on the tank for reducing chromium emissions.

3. Principle. During chromium electroplating or anodizing operations,

bubbles of hydrogen and oxygen gas generated during the process rise to the surface of the tank liquid and burst. Upon bursting, tiny droplets of chromic acid (chromium mist) become entrained in the air above the tank. Because the chrome tank cover completely encloses the air above the tank, the chromium mist either falls back into the solution because of gravity or collects on the inside walls of the chrome tank cover and runs back into the solution. A semi-permeable membrane allows passage of the hydrogen and oxygen out of the chrome tank cover. A lit smoke device is placed inside the chrome tank cover to detect leaks at the membrane, joints, or seals.

4. Apparatus

5. Smoke device. Adequate to generate 500 to 1000 ft 3 of smoke/20 ft 2 of

tank surface area (e.g., Model #1A=15 SECONDS from Superior Signal, New York).

6. Small container. To hold the smoke device.

7. Procedure

Place the small container on a stable and flat area at center of the chrome tank cover (you can use a board and place it on the buss bars). Place the smoke device inside the container. After lighting the smoke device, quickly close the access door to avoid smoke from escaping. Let smoke device completely burn; entire space under the

chrome tank cover will now be filled with the smoke. Observe for leaks of smoke from each seal, joint, and membrane of the chrome tank cover. Record these observations including the locations and a qualitative assessment of any leaks of smoke.

When all seals, joints, and membranes have been observed, evacuate

the unit to remove the smoke from the chrome tank cover.52

Appendix 7 – Alternative Requirements for Enclosed Hexavalent Chromium Electroplating Facilities – Mass Emission Rate Calculation Procedure

Mass Emission Rate shall be calculated using the following equation:

MAMER = ETSA x K x 0.015 mg/dscm

Where:

MAMER = the alternative emission rate for enclosed hexavalent chromium electroplating tanks in mg/hr.

ETSA = the hexavalent chromium electroplating tank surface area in square feet (ft 2 ).

K = a conversion factor, 425 dscm/(ft 2 x hr).55

Appendix 8 – Surface Tension Procedure for a Stalagmometer

The stalagmometer must first be properly cleaned before being used for the first time and after a period of storage. Properly clean the stalagmometer using the following procedure:

1. Set up stalagmometer in stand in a fume hood.

2. Place a clean 150 mL beaker underneath the stalagmometer then fill with reagent grade concentrated nitric acid. Immerse bottom tip (approximately 1⁄2”) of stalagmometer into the beaker.

3. Squeeze rubber bulb and pinch at the arrow up (1) position to collapse. Place bulb end securely on top end of stalagmometer. Carefully draw the nitric acid by pinching the arrow up (1) position until the level is above the top etched line.

4. Allow nitric acid to remain in stalagmometer for 5 minutes and then carefully remove the bulb allowing the acid to completely drain.

5. Fill a clean 150 mL beaker with distilled or deionized water. Using the rubber bulb per the instructions in Step #3, rinse and drain stalagmometer

with deionized or distilled water until the inside is “water break” free.

6. Fill a clean 150 mL beaker with isopropyl alcohol. Again using the rubber bulb per Step #3, rinse and drain stalagmometer twice with isopropyl alcohol and allow the stalagmometer to dry completely.

7. Take a sample of the solution to be tested and adjust the solution to room temperature. Measure the specific gravity and record reading.

8. Fill a clean 150 mL beaker with solution to be tested. Immerse bottom end of stalagmometer into the beaker. Fill the stalagmometer per instructions in Step #3, making sure that the solution level is above the top

etched line.

9. Raise the stalagmometer so that the bottom end is completely out of solution. Remove bulb and immediately place a finger on the top end of the stalagmometer. Carefully use the finger to bring the solution level down to the top etched line. Do not release finger at this time.

10. “Wipe” the excess solution on the lower tip by touching it against the

side of the beaker.

11. Release fingertip to allow solution to drain and count number of drops

until the level reaches the bottom etched line.56 Calculations for Surface Tension

Surface tension (dynes/cm) = Sw * Nw * D

N * Dw

Sw = Surface tension of water at 25 o C or 77 o F (72.75 dynes/cm) Nw = water drop number etched on instrument D = measured specific gravity (g/ml) N = # of solution drops Dw = water density (1.0 g/mL)

PRECAUTIONS:

1. Make sure the stalagmometer is clean (no sludge or film) 2. No chips, cracks, etc 3. Vertical placement

4. No vibration 5. 20 drops per minute rate (10 dynes/cm) +/- 1 drop per minute 6. Performance checked with water. The number of drops etched on the instrument shall be verified with deionized water to +/- 1 drop. If the number of drops are not within 1 drop, then the Stalagmometer shall be cleaned. If the cleaning process does not bring the drop count within 1 drop of the etched number on the instrument, then the operator shall: a) Purchase a new Stalagmometer; or b) Use the number of drops recorded for the distilled water run as (Nw) in the equation instead of the number of drops etched on the Stalagmometer

Appendix 9--Information to be Submitted to the Permitting Agency when Demonstrating an Alternative Method or Methods of Compliance Pursuant to section 93102.4(b)(3)

The owner or operator of a facility applying for approval of an alternative method of compliance must submit to the permitting agency the following information:

1. A performance test as specified in Section 93102.7. The test shall

have been conducted in a manner consistent with normal electroplating or anodizing operations.

2. A demonstration that the alternative method achieves an equal or

greater amount of reductions in hexavalent chromium emissions than would be achieved with direct compliance with the applicable

emission rate in Table 93102.4.

3. Calculations based on scientifically valid risk assessment

methodologies demonstrating that the alternative method results in reducing risk equally or greater than the risk reduction that would be achieved by direct compliance with the applicable emission rate in Table 93102.4. A facility using in-tank controls only must be modeled as a volume source and the resulting risk compared to the same facility modeled as a point source.

4. Documentation which demonstrates that the method is enforceable,

including an operation and maintenance plan, an inspection and maintenance schedule, and a recordkeeping plan.
