Section 30D-1.0 - Introduction

1.1 Applicability. This procedure is applicable for determining the fugitive VOC emissions from a TTE. It is intended to be used as a segment in the development of liquid/gas or gas/gas protocols for determining VOC CE for surface coating and printing operations.

1.2 Principle. The amount of fugitive VOC emissions (F) from the TTE is calculated as the sum of the products of the VOC content (C_Fj), the flow rate (Q_Fj), and the sampling time (0_F) from each fugitive emissions point.

1.3 Estimated Measurement Uncertainty. The measurement uncertainties are estimated for each fugitive emission point as follows:

Q_Fj = ±5.5% and C_Fj = ±5.0%. Based on these numbers, the probable uncertainty for F is estimated at about ±7.4%.

1.4 Sampling Requirements. A CE test shall consist of at least three sampling runs. Each run shall cover at least one complete production cycle, but shall be at least three hours long. The sampling time for each run need not exceed eight hours, even if the production cycle has not been completed. Alternative sampling times may be used with the approval of the Department.

1.5 Notes. Because this procedure is often applied in highly explosive areas, caution and care should be exercised in choosing, installing, and using the appropriate equipment. Mention of trade names or company products does not constitute endorsement. All gas concentrations (percent, ppm) are by volume, unless otherwise noted.
