Plant 3 Tank 2006 and Tank 3201 Vapor Control Project

This project will install asphalt vapor control devices on two existing storage tanks, which is expected to ensure zero percent opacity from each tank roof vent. The vapor control is also designed to reduce opacity and lower VOC, PM and H₂S emissions.

Emissions from each tank will first be routed through a particulate filter system and then to a carbon-based adsorption control device. The filter and carbon adsorption bed capture asphalt vapors that contribute to opacity.

40 CFR 60 Subpart UU is a New Source Performance Standard (NSPS) established in 1982 that regulates emissions from asphalt storage tanks, requiring zero percent opacity (no visible emissions), except in certain circumstances, from asphalt storage tanks constructed or modified after certain dates.

Construction is expected to conclude in 2027.

We do not expect an increase in vehicle traffic or noise from this project. All work would be completed within the refinery fenceline.

Once complete, the project is expected to control opacity and reduce emissions intensity of Volatile Organic Compounds (VOC), Particulate Matter (PM) and Hydrogen Sulfide (H2S).

We continuously monitor the air surrounding our operations and provide air quality data and information for neighbors and the public. Near real-time air information from the community and fenceline monitoring systems is available on our Community Air Monitoring page and on www.ccnd-air.com.
