Air Compliance Testing's approach to determining the Volatile Organic Compound (VOC) Capture Efficiency (CE) closely correlates with the testing protocols outlined within the January 9, 1995 EPA document, Guidelines for Determining Capture Efficiency (EPA Method 204 series). This is the document that is typically referenced in your EPA Air Permit "Terms and Conditions" Testing Requirement's section as the guideline document for use in determining an acceptable CE Test Protocol. Air Compliance Testing has extensive experience in performing these CE Test Protocols on various types of VOC emitting devices. This document contains multiple test protocol options (i.e., a mass balance approach, a Temporary Total Enclosure (TTE) construction approach, etc.) that are uniquely applied to specific types of processes that require a CE determination test. In order to appropriately select and use one of the EPA's test protocol options contained in this document, or to compile a custom test protocol that would meet the data quality objective required for acceptance by the EPA, a thorough scientific assessment of your specific process usually needs to be performed. In most cases, a preliminary (pre-compliance demonstration) stack test may also be required in order to determine if the proposed test protocol is in-fact going to result in an acceptable CE result.

At this point you may be asking yourself "Why can't Air Compliance Testing just select one of the EPA's standard test protocols and give us a price for performing it?"

The answer to that question is that we can provide you with a price. However, our experience has taught us that the initially proposed protocol and its corresponding price is not usually the one that will ultimately be used to demonstrate compliance. In order to avoid misleading you during the proposal development phase of a project, we have adopted a policy to provide you with a "typical" range of pricing for this type of work so you can properly appropriate your project's budget.
