This report details a passive sampling campaign for BTEX compounds (benzene, toluene, ethyl-benzene, and xylene) conducted at the Chevron Cape Town Refinery from June 2010 to June 2011. The study monitored air quality across 12 locations to assess compliance with national and international ambient air quality standards.

• The national ambient air quality annual average standard for benzene, set at 10ug/m*, was not exceeded at any of the monitored sites between June 2010 and June 2011.
• Benzene levels showed a significant decrease over several years, specifically at the Loading Bay site, where annual levels dropped from 14.24ug/m* in the 2009-2010 period to 7.59y1g/m* in the 2010-2011 period.
• A more stringent benzene annual average standard of 5yg/m*, accepted by the Northern Communities air monitoring task group (NCamtg) and scheduled to become the national standard on 1 January 2015, was exceeded at the West Fence and Loading Bay sites.
• The monitoring campaign found that accepted standards and guidelines for xylene, ethyl-benzene, and toluene were not exceeded during the review period.
• Elevated benzene levels at the West Fence and Loading Bay sites are likely due to emissions from the petrol loading facility, given that prevailing winds typically blow from the south, south-east, and north-west.
• The study recommends replacing the existing Loading Bay sampler with a single site at the outer fence-line of the parking area near the loading bay, as the outer fence-line was found to be more representative for ambient standard assessments.
