Section 7:27B-3.17 - Procedures for the determination of volatile organic compounds emitted from petroleum solvent dry cleaning operations

(a) The method in this section is applicable for the determination of the final recovered solvent flow rate at the completion of the recovery cycle, and the VOC content in all filtration waste. For the same circumstances as described above, any alternative method shall be submitted to the Department for review, pursuant to 7:27B-3.2(c), (d), and (e).

(b) This method is based upon:

1. The determination of the volume of the recovered solvent; and

2. The separation and weight determination of the solvent.

(c) The following is a summary of this method:

1. The recovered solvent is diverted to a graduated cylinder at the end of the recovery cycle. The volume of solvent recovered during a one minute period is measured and recorded.

2. The recovered solvent is separated from other filtration waste and weighed.

(d) The procedure for this section shall be as follows:

1. Recovered solvent shall be determined as follows:

i. The flow rate of the recovered solvent is measured at the outlet of the solvent-water separator;

ii. The flow rate of the recovered solvent is measured at the end of the solvent recovery phase;

iii. Divert the flow of the recovered solvent to a graduated cylinder;

iv. Record the volume of recovered solvent to the nearest milliliter, after a one minute interval;

v. Record the type of articles cleaned and the length of the recovery cycle; and

vi. Repeat steps i-v over three cleaning cycles.

2. The solvent content in filtration waste shall be determined as follows:

i. Collect three one-kilogram samples of still and filtration waste in air-tight containers which are impervious to petroleum solvents;

ii. Record the total mass of articles in kilograms cleaned since the last still boildown or filter change;

iii. Record the total mass of still and filter water in kilograms produced since the last waste removal;

iv. Determine the solvent content of the still and filter water using the procedure specified in ASTM D322-80, "Standard Test Method for Gasoline Dilutent in Used Gasoline Engine Oils by Distillation" (7:27B-3.18, Reference 15); and

v. Report the results as mass of VOC per mass of dry weight of articles dry cleaned in kilograms per kilogram.
