While air pollution regulations have remained fairly static, equipment upgrades continue to minimize compliance woes.

The EPA has long been concerned about emission control systems’ ability to continue meeting the required compliance levels after initial tests are performed. To keep companies in check, the EPA Emission Measurement Center is developing monitoring protocol, which will require companies to verify continued compliance and record the data. This will provide authorities assurance that installed systems are working properly. Companies considered major sources of emissions (or which fall under a MACT rule) will be required to develop and maintain a compliance-monitoring schedule.
