Emissions control and monitoring involves the implementation of measures to reduce air emissions of pollutants such as greenhouse gases (GHGs), volatile organic compounds (VOCs), nitrogen oxides (NOx), sulfur dioxide (SO2), particulate matter (PM), and hazardous air pollutants (HAPs) from various sources including production, refining, transportation, and distribution processes.

Continuous emissions monitoring systems (CEMS) are installed and maintained including other monitoring equipment to measure, record, and report emissions of regulated pollutants in real-time from stationary sources. Conducting periodic emissions testing, stack sampling, and performance evaluations to verify compliance with emission limits, calibrate monitoring equipment, and identify opportunities for emission reductions is required.

Engagement with stakeholders, including communities, regulators, environmental organizations, investors, and the public, to communicate emission reduction efforts, environmental performance, and sustainability initiatives is paramount.
