SAN DIEGO COUNTY AIR POLLUTION CONTROL DISTRICT
RULE 260.313 - PERFORMANCE TESTS AND COMPLIANCE PROVISIONS
(a) Rule 260.8(d) and 260.8(f) do not apply to the performance test procedures required by this subpart.
(b) The owner or operator of an affected facility shall conduct an initial performance test as required under
Rule 260.8(a) and thereafter a performance test each calendar month for each affected facility according to the
procedures in this rule.
(c) The owner or operator shall use the following procedures for determining monthly volume-weighted average
emissions of VOC's in kilograms per liter of coating solids applied (G).
- An owner or operator shall use the following procedures for any affected facility which does not use a capture
system and control device to comply with the emissions limit specified under Rule 260.312. The owner or operator
shall determine the composition of the coatings by formulation data supplied by the manufacturer of the coating
or by an analysis of each coating, as received, using Reference Method 24. The Control Officer may require the
owner or operator who uses formulation data supplied by the manufacturer of the coating to determine the VOC content
of coatings using Reference Method 24. The owner or operator shall determine the volume of coating and the mass
VOC-solvent used for thinning purposes from company records on a monthly basis. If a common coating distribution
system serves more than one affected facility or serves both affected and existing facilities, the owner or operator
shall estimate the volume of coating used at each facility by using the average dry weight of coating and the surface
area coated by each affected and existing facility or by other procedures acceptable to the Control Officer.
(i) Calculate the volume-weighted average of the total mass of VOC's consumed per unit volume of coating solids
applied (G) during each calendar month for each affected facility, except as provided under Rule 260.313(c)(2)
and (c)(3). Each monthly calculation is considered a performance test. Except as provided in Subsection (c)(1)(iv)
of this rule, the volume-weighted average of the total mass of VOC's consumed per unit volume of coating solids
applied (G) each calendar month will be determined by the following procedures.
(A) Calculate the mass of VOC's used (M_{o} + M_{d}) during each calendar month for each affected
facility by the following equation:
(L_{dj}D_{dj} will be 0 if no VOC solvent is added to the coatings, as received.)
Where:
n is the number of different coatings used during the calendar month and m is the number of different diluent VOC-solvents
used during the calendar month.
(B) Calculate the total volume of coating solids used (L_{s)} in each calendar month for each affected
facility by the following equation:
Select the appropriate transfer efficiency from Table 1. If the owner or operator can demonstrate to the satisfaction
of the Control Officer that other transfer efficiencies other than those shown are appropriate, the Control Officer
will approve their use on a case-by-case basis. Transfer efficiency values for application methods not listed below
shall be determined by the Control Officer on a case-by-case basis. An owner or operator must submit sufficient
data for the Control Officer to judge the accuracy of the transfer efficiency claims.

Where more than one application method is used within a single surface coating operation, the owner or operator
shall determine the composition and volume of each coating applied by each method through a means acceptable to
the Control Officer and compute the weighted average transfer efficiency by the following equation:
Where:
n is the number of coatings used and
p is the number of application methods used.
(C) Calculate the volume weighted average mass of VOC's consumed per unit volume of coating solids applied (G)
during the calendar month for each affected facility by the following equation:
(ii) Calculate the volume-weighted average of VOC emissions to the atmosphere (N) during the calendar month for
each affected facility by the following equation:
(iii) Where the volume-weighted average mass of VOC discharged to the atmosphere per unit volume of coating solids
applied (N) is less than or equal to 0.90 kilogram per liter, the affected facility is in compliance.
(iv) If each individual coating used by an affected facility has a VOC content, as received, which when divided
by the lowest transfer efficiency at which the coating is applied, results in a value equal to or less than 0.90
kilogram per liter, the affected facility is in compliance provided no VOC's are added to the coatings during distribution
or application.
- An owner or operator shall use the following procedures for any affected facility that uses a capture system
and a control device that destroys VOC's (e.g., incinerator) to comply with the emission limit specified in Rule
260.312.
(i) Determine the overall reduction efficiency (R) for the capture system and control device. For the initial performance
test the overall reduction efficiency (R) shall be determined as prescribed in Subsections (c)(2)(i)(A), (B), and
(C) of this rule. In subsequent months, the owner or operator may use the most recently determined overall reduction
efficiency (R) for the performance test providing control device and capture system operating conditions have not
changed. The procedure is Subsections (c)(2)(i)(A), (B), and (C), of the rule shall be repeated when directed by
the Control Officer or when the owner or operator elects to operate the control device or capture system at conditions
different from the initial performance test.
(A) Determine the fraction (F) of total VOC's emitted by an affected facility that enters the control device using
the following equation:
(C) Determine overall reduction efficiency (R) using the following equation:
(ii) Calculate the volume-weighted average of the total mass of VOC's per unit volume of coating solids applied
(G) during each calendar month for each affected facility using equations in Subsections (c)(1)(i)(A), (B), and
(C) of this rule.
(iii) Calculate the volume-weighted average of VOC emissions to the atmosphere (N) during each calendar month
by the following equation:
(iv) If the volume-weighted average mass of VOC's emitted to the atmosphere for each calendar month (N) is less
than or equal to 0.90 kilogram per liter of coating solids applied, the affected facility is in compliance. Each
monthly calculation is a performance test.
- An owner or operator shall use the following procedures for any affected facility which uses a control
device that recovers the VOC's (e.g., carbon adsorber) to comply with the applicable emission limit specified under
Rule 260.312.
(i) Calculate the total mass of VOC's consumed (M_{o} + M_{d}) and the volume-weighted average
of the total mass of VOC's per unit volume of coating solids applied (G) during each calendar month for each affected
facility using equations in Subsection (c)(1)(i)(A), (B), and (C) of this rule.
(ii) Calculate the total mass of VOC's recovered (M_{r}) during each calendar month using the following
equation:
(iii) Calculate overall reduction efficiency of the control device (R) for each calendar month for each affected
facility using the following equation:
(iv) Calculate the volume-weighted average mass of VOC's emitted to the atmosphere (N) for each calendar month
for each affected facility using equation in Subsection (c)(2)(iii) of this rule.
(v) If the weighted average mass of VOC's emitted to the atmosphere for each calendar month (N) is less than or
equal to 0.90 kilogram per liter of coating solids applied, the affected facility is in compliance. Each monthly
calculation is a performance test.
