II. Emission Calculations From Powder Coating
Particulate Emissions (PM10)
Daily Emissions =
pounds of powder sprayed per day x (1 - TE) x (1 - CE) =
where TE = transfer efficiency = 0.65 for electrostatic guns (default)
CE = Control Efficiency of control device
= 0.99 for dust collector - baghouse/cartridge
= 0.9 for standard spray booth with pocket type filters
30 day average emission = (
daily emissions x number of days of operation per month) / 30 =
Yearly emissions (tons/year) = monthly emissions x 12 / 2000
(
daily emissions x number of days of operation per month) x 12 / 2000 =
III. VOC Emissions
Powder Coating
Daily Emissions = 0.01 x
pounds of powder sprayed per day =
Assume 1% by weight of powder sprayed is volatized
30 day average emission = (
daily emissions x number of days of operation per month) / 30 =
Yearly emissions (tons/year) = monthly emissions x 12 / 2000
(
daily emissions x number of days of operation per month) x 12 / 2000 =
From Solvent Usage, Daily Emissions
Part Cleaning
Loss per day
% by weight of VOC x gallons/day x density =
30 day average emission = (
daily emissions x number of days of operation per month) / 30 =
Yearly emissions (tons/year) = monthly emissions x 12 / 2000
(
daily emissions x number of days of operation per month) x 12 / 2000 =
Gun Cleaning
Loss per day
% by weight of VOC x gallons/day x density =
30 day average emission = (
daily emissions x number of days of operation per month) / 30 =
Yearly emissions (tons/year) = monthly emissions x 12 / 2000
(
daily emissions x number of days of operation per month) x 12 / 2000 =
If a separate permit is required for an oven, calculate oven emissions.

SAMPLE Conditions:
1) OPERATION OF THIS EQUIPMENT SHALL BE CONDUCTED IN ACCORDANCE WITH ALL
DATA AND SPECIFICATIONS SUBMITTED WITH THE APPLICATION UNDER WHICH THIS
PERMIT IS ISSUED UNLESS OTHERWISE NOTED BELOW.
2) HIS EQUIPMENT SHALL BE PROPERLY MAINTAINED AND KEPT IN GOOD OPERATING
CONDITION AT ALL TIMES.
3) THIS SPRAY BOOTH SHALL NOT BE OPERATED UNLESS ALL EXHAUST AIR PASSES
THROUGH FILTER MEDIA AT LEAST 2 INCHES THICK.
4) A GAUGE SHALL BE INSTALLED AND MAINTAINED TO INDICATE, IN INCHES OF WATER,
THE STATIC PRESSURE DIFFERENTIAL ACROSS THE EXHAUST FILTERS. IN OPERATION,
THE PRESSURE DIFFERENTIAL SHALL NOT EXCEED 0.25 INCH OF WATER.
5) THIS EQUIPMENT SHALL BE OPERATED IN COMPLIANCE WITH RULES 1107 AND 1171.
6) MATERIAL SAFETY DATA SHEETS FOR ALL COATINGS AND SOLVENTS USED AT THIS
FACILITY SHALL BE KEPT CURRENT AND MADE AVAILABLE TO DISTRICT PERSONNEL

7) WET COATING SHALL NOT BE APPLIED IN THIS EQUIPMENT.
8) THE OPERATOR SHALL COMPLY WITH RULE 109 (RECORDKEEPING FOR VOLATILE
ORGANIC COMPOUND EMISSIONS).
9) IN ADDITION TO THE REQUIREMENTS OF RULE 109, THE OPERATOR SHALL KEEP
ADEQUATE RECORDS FOR THIS FACILITY TO VERIFY CALENDAR MONTHLY VOLATILE
ORGANIC COMPOUNDS (VOC) EMISSIONS IN POUNDS AND THE VOC CONTENT OF EACH
MATERIAL AS APPLIED (INCLUDING WATER AND EXEMPT COMPOUNDS). ALL RECORDS
SHALL BE PREPARED IN A FORMAT WHICH IS ACCEPTABLE TO THE DISTRICT.
10) THE VOC EMISSIONS FROM THE USE OF ANY POWDER COATINGS SHALL BE
CALCULATED USING THE EMISSION FACTOR DETERMINED PURSUANT TO SCAQMD
METHOD 316C. IN CASE NO LABORATORY TESTED EMISSION FACTOR IS AVAILABLE,
THEN A FACTOR OF 0.01 POUND OF VOC PER POUND OF POWDER COATING SPRAYED
SHALL BE USED.
11) THE TOTAL QUANTITY OF POWDER COATINGS USED IN THIS EQUIPMENT SHALL NOT
EXCEED
POUNDS IN ANY ONE DAY.
12) THE TOTAL QUANTITY OF VOLATILE ORGANIC COMPOUND (VOC) EMISSIONS FROM ALL
PERMITTED EQUIPMENT AND ASSOCIATED OPERATIONS AT THIS FACILITY SHALL NOT
EXCEED 667 POUNDS IN ANY ONE CALENDAR MONTH. ASSOCIATED OPERATIONS
INCLUDE, BUT ARE NOT LIMITED TO SURFACE PREPARATION, EQUIPMENT CLEANUP,
AND THE APPLICATION OF ANY OTHER MATERIALS TO PARTS THAT ARE
SUBSEQUENTLY PROCESSED IN THE PERMITTED EQUIPMENT.

13) WITHIN 14 CALENDAR DAYS AFTER THE END OF EACH MONTH, THE OPERATOR SHALL
TOTAL AND RECORD VOC EMISSIONS FOR THE MONTH FROM ALL EQUIPMENT
COVERED BY THE MONTHLY LIMIT. THE RECORD SHALL INCLUDE ANY PROCEDURES
USED TO ACCOUNT FOR CONTROL DEVICE EFFICIENCIES AND/OR WASTE DISPOSAL. IT
SHALL BE SIGNED AND CERTIFIED FOR ACCURACY BY THE HIGHEST RANKING
INDIVIDUAL RESPONSIBLE FOR COMPLIANCE WITH DISTRICT RULES.
14) THE OPERATOR SHALL RETAIN FOR 36 MONTHS ALL PURCHASE INVOICES FOR ALL
VOC-CONTAINING MATERIAL USED OR STORED AT THE FACILITY, AND ALL WASTE
MANIFESTS FOR ALL WASTE VOC-CONTAINING MATERIAL REMOVED FROM THE
FACILITY.
15) THE OPERATOR SHALL MAINTAIN A SINGLE LIST THAT INCLUDES ONLY THE NAME AND
ADDRESS OF EACH PERSON FROM WHOM THE FACILITY ACQUIRED VOC-CONTAINING
MATERIAL REGULATED BY THE DISTRICT THAT WAS USED OR STORED AT THE FACILITY
