Stack Test Data

Johnson Controls is required to test its processes for air pollutant emissions. The test results are used to determine if the facility is in compliance with the emission limitations in its air permit. A facility may use its own stack testing group or hire a third party contractor to conduct the stack tests. In preparation for testing, facilities must prepare a Stack Test Protocol. It is the responsibility of DHEC to approve or disapprove the Stack Test Protocol. Like all facilities, Johnson Controls is required to notify DHEC at least 15 days before the test to give us the opportunity to observe the test. Once the stack tests are conducted, the facility must send a report of the results to DHEC for review. If the results are validated, DHEC will issue a letter approving the stack test. The links below will provide future information about the stack tests.
