Instructions for Form B4-6H “EMISSION SOURCES-
MISCELLANEOUS SURFACE COATING/AUTOBODY REFINISHING”
One Form B4-6Hmust be completed for eachemission source (prep station, paint booth, and other emission sources) involving miscellaneous spray painting/coating operations. Make as many copies of the form as necessary; two copies are included with this instruction. If two or more emissions sources are identical, then one form may be used to represent all of the units, but each unit must have its own Emission Source ID No. and be indicated on the form. This form is available on the MCAQ website at: . and can be downloaded for submission.1.0 EMISSION SOURCE
1.1TYPE OF SOURCE – Specify the applicable type of source, or if other, then describe in comments section. If you use portable or stationary internal combustion engines/generators on site (this does not include the vehicles being painted/coated), additional rules will apply (call MCAQ at (704) 326-5430).
1.2For prep stations or spray booths, the design must be compliant with 40 CFR 63 Subpart HHHHHH (“Subpart 6H”) requirements by the compliance date. Indicate whether the design meets the regulatory requirements. The regulation may be found at:
1.3EMISSION SOURCE DESCRIPTION – Describe each emission source for which application is made. Emission source is defined as any stationary article, machine, process equipment, or other contrivance, or combination thereof, from which air pollutants emanate or are emitted, either directly or indirectly. If two or more emissions sources are identical (e.g., spray booths that are the same manufacturer and model #)may be listed once, but this description should specify the number of individual pieces of equipment included.
1.4EMISSION SOURCE ID No. Enter the emission source ID No. for the emission source being described on this form. The ID No. will begin with ES- with the choice of the following numbers or letters at the discretion of the applicant. For identical emission sources/equipment grouped together, each unit must have its own Emission Source ID No.
1.5MANUFACTURER Enter the manufacturer of the emission source.
1.6MODEL NO. – Enter the model number of the emission source.
1.7MAXIMUM NO. OF UNITS PROCESSED – Enter the maximum expected or actual production rate/number of units processed on weekly basis and annually. This should be the maximum number of units (cars, trucks, parts, etc.) processed per week and annually (use highest actual in the last 5 years, or maximum planned) that the facility can handle.
1.8METHOD OF SPRAY – Check the type of spray applicator used in the coating operation if applicable to the emission unit being described. The spray guns listed are those permitted by the Subpart 6H regulation. If an equivalent spray gun is listed, it must have EPA approval, and you must supply a copy of the EPA equivalency determination with this form.
1.9NUMBER OF GUNS PER STATION – Specify the number of spray guns used with the emission unit if applicable.
TRANSFER EFFICIENCY – Enter the % (expressed as decimal) of solid which actually is applied to items being sprayed, take into consideration solid lost due to overspray, etc. Use the following default values or provide documentation for other. The numbers below are typical. Your numbers may vary:
.25 – air atomized
.25 – airless spray
.60 – manual electrostatic spray
.70 – nonrotational automatic electrostatic spray
.80 – rotating head electrostatic (manual and automatic)
.90 – dip coat and flow coat
.95 – electrodeposition
PARTICULATE CAPTURE EFFICIENCY – Enter the % (expressed as decimal) of overspray which is captured from the process and sent to the exhaust air stream. The capture efficiency will generally approach 100% for three-sided spray booths operating under sufficient negative pressure.
1.10 EXHAUST CONTROL – Specify the applicable exhaust control method, or if other, then describe in comment section.
2.0 FUEL USAGE
2.1 TOTAL MAXIMUM FIRING RATE (million Btu/hour) – Many coating operations require the use of dryers, heaters, or ovens to speed the drying process. This does not include building comfort heating or sanitary water heating. If there are any heaters associated with the coating operation, enter the total maximum firing rate for all process burners,if any, based on the heat input.
2.2 HEATING METHOD – Specify the method of heating as direct fired, electric, steam, or other.
2.3 FUEL USED –Specify the type of fuel used if there is any associated with the process or if stationary or portable engines are used (e.g., diesel, no.2 fuel oil, natural gas, LPG, etc.).
2.4 ACTUAL FUEL USAGE
- ANNUAL – Enter the actual amount of fuel consumed in one year by the emission source.
- HOURLY – Enter the actual amount of fuel consumed in one hour.
- UNITS – Enter the units of the listed fuel (e.g., gallons, cubic feet, pounds, etc.).
- ANNUAL – Enter the maximum amount of fuel consumed in one year by the emission source..
- HOURLY – Enter the maximum amount of fuel consumed in one hour.
- UNITS – Enter the units of the listed fuel (e.g., gallons, cubic feet, pounds, etc.).
3.0 COMMENTS
This section should be used to describe any entry requiring additional explanation.
Note: Emissions from the coating operations should be calculated and submitted using form D1-6H.
