It is our stated goal that there should be no harm to people or the environment as a result of our operations. Health, safety and the environment carry as much weight as other business priorities and are regarded as critical to the operation of our business.

Sulphur Dioxide (SO₂) Emissions

SAPREF are required to monitor and report all SO2 exceedances in terms of the Schedule Trade permit and the APPA permit. The Schedule Trade permit, acquired during 2006 imposed a SO2 limit of 20t/d on average per annum, which is the same as SAPREF's self-imposed limit. During 2006, SAPREF's annual average SO2 was 11t/d, which is well below the 20t/d limit.

Nitrogen Oxide (NOx) Emissions

NOx emissions increased from 1214 tons in 2005 to 1301 tons in 2006. Low NOx burners are specified for new installations. This figure was slightly higher than the 2006 target of 1300 tons per annum. NOx emissions is a function of the amount of fuel oil that is consumed.

Volatile Organic Compounds (VOC) Emissions

There was a significant decrease of VOC emissions during 2006 as compared to 2005. This reduction has been attributed to the decrease in production rates during 2006. The leak detection survey continued during 2006 by SNC Lavalin (Canada) with a projected completion roll-out plan of 2007/8. The retrofitting of double seals on floating roof tanks continues to progress on the refinery and was completed on the refinery.

Carbon Dioxide (CO2) Emissions

CO2 emissions decreased from 1344 in 2005 to 978 in 2006. This is related to the lower production as a result of the extended turnaround during 2006.

Effluent

The average oil concentration in effluent increased from 17mg/lit (milligrams per litre) in 2005 to 29mg/lit in 2006, which is still well within the eThekwini Municipality's Bylaw limit of 50mg/lit. The primary cause of the increase in oil in effluent concentration were activities occurring during the 2006 turnaround. A stronger emphasis is being placed on identifying and minimizing the pollution at source within the refinery, while ensuring that internal service level agreements are developed and maintained to ensure compliance.
