6.25 Miscellaneous Organic Evaporation

6.25.1 Emissions

Introduction

This category contains various types of equipment identified in the permit data bank as not defined in the many other categories and therefore designated as “other” equipment. Emissions from this category are from various sources and different industrial processes. The emissions for these point sources are contained in the permit data bank.

Methodology

This category contains emissions from point sources only. Point source emissions are calculated from a facility’s equipment operating data submitted as part of the permit approval process. The Data Bank contains throughput information from sources submitted by individual plants. Emissions are then calculated by using specific emission factors for a particular source operation supplied by the company. If no specific factor is available, a generalized factor developed by district staff engineer is used to determine emissions.

Monthly Variation

The data bank contains throughput data for each month provided by companies holding District permits.

County Distribution

Emissions distributed into counties were based on actual locations of the plants in the Bay Area.
