A. The sampling site for vent streamflow rate and molar composition shall be prior to thefinal recovery device and prior to the point at whichthe nonair oxidation stream is introduced.

B. The efficiency of the finalrecovery device is determined by measuring the VOCconcentration using Method 18 at the inlet to the finalrecovery device after the introduction of any nonairoxidation vent stream and at the outlet of the finalrecovery device.

C. This efficiency is applied to theVOC concentration measured prior to the finalrecovery device and prior to the introduction of thenonair oxidation stream to determine theconcentration of VOC in the air oxidation streamfrom the final recovery device. This concentration ofVOC is then used to perform the calculations outlinedin sections 39.5.l. and 39.5.m.

j. The molar composition of the process ventstream shall be determined as follows:

1. Method 18 to measure theconcentration of VOC including those containinghalogens.

l. The net heating value of the vent streamshall be calculated using the following equation:

where:HT = Net heating value of the sample, MJ/scm,

where the net enthalpy per mole ofoffgas is based on combustion at 25ECand 760 mm Hg, but the standardtemperature for determining the volumecorresponding to one mole is 20EC, as inthe definition of Qs (offgas flow rate).

kcal/g-mole, based on combustion at25EC and 760 mm Hg. The heats ofcombustion of vent stream componentswould be required to be determinedusing ASTM D2382-76 if publishedvalues are not available or cannot becalculated.

m. The emission rate of VOC in the processvent stream shall be calculated using the followingequation:

where:EVOC= Emission rate of VOC in the sample,

kg/hr K2 = Constant, 2.494 x 10-6 (1/ppm) (g-

mole/scm) (kg/g) (min/hr), where standard temperature for (g-

mole/scm) is 20EC. Cj = Concentration on a dry basis of

compound j in ppm as measured by Method 18 as indicated in section 39.5.j.

organic compound (VOC) capture systems.

a. Definitions and abbreviations. -- Forpurposes of this section 44., the following definitionsand abbreviations apply:

1. "Gas/gas method" means either of twomethods for determining capture which rely only ongas phase measurements. One method requiresconstruction of a temporary total enclosure (TTE) toassure all potential fugitive emissions are measuredwhile the other method uses the room or buildingwhich houses the source as an enclosure.

2. "Hood" means a partial enclosure orcanopy for capturing and exhausting, by means of adraft, the organic vapors or other fumes rising from acoating process or other source.

3. "Liquid/gas method" means either oftwo methods for determining capture which requireboth gas phase and liquid phase measurements andanalysis. One liquid/gas method requires constructionof a temporary total enclosure, the other uses thebuilding or room which houses the facility as anenclosure.

4. "Process line" means any coating line,coating operation, or printing press.

5. "PTE" is a permanent total enclosure,which contains a process that emits VOC and meetsthe specifications given in Procedure T in AppendixA of this regulation.

6. "TTE" is a temporary total enclosurewhich is built around a process that emits VOC andmeets the specifications given in Procedure T inAppendix A of this regulation.

B. If the solvent recovery systemcontrols multiple process lines, the source owner oroperator shall be able to demonstrate that the overallcontrol (i.e., the total recovered solvent VOC dividedby the sum of liquid VOC input to all process linesventing to the control system) meets or exceeds themost stringent standard applicable for any processline venting to the control system.

a. If either the zero (or low-level) or high-level CD exceeds twice the applicable driftspecification in 40 CFR Part 60, Appendix B, for fiveconsecutive daily periods, the CEMS is out-of-control.

b. If either the zero (or low-level) or high-level CD exceeds four times the applicable driftspecification in 40 CFR Part 60, Appendix B, duringany CD check, the CEMS is out-of-control.

c. If the CEMS fails a performance audit(PA), the CEMS is out-of-control.

48.3. Determining the out-of-control time period

for the CEMS.

a. The beginning of the out-of-control periodis:

1. The time corresponding to thecompletion of the fifth consecutive daily CD checkwith CD in excess of two times the allowable limit, or

2. The time corresponding to completionof the daily CD check preceding the daily CD checkthat results in a CD in excess of four times theallowable limit.

b. The end of the out-of-control period is thetime corresponding to the completion of the CDcheck following corrective action that results in theCD's at both the zero (or low-level) and high-levelmeasurement points being within the correspondingallowable CD limit (i.e., either two times or fourtimes the allowable limit in 40 CFR Part 60,Appendix B).

c. If the CEMS failed a PA, the beginning ofthe out-of-control period is the time corresponding tothe completion of the failed audit test. The end of theout-of-control period is the time corresponding to asuccessful retest of the PA sample.

48.4. Recordkeeping. -- The owner or operatorshall keep the QC procedure described in section48.1. in a readily accessible location for at least 3years and shall make the procedure available to theDirector upon verbal or written request.

48.5. Reporting. -- The owner or operator shallsubmit all information concerning out-of-controlperiods including beginning and end dates anddescriptions of corrective actions taken in the excessemissions report defined in 40 CFR 60.7(c).
