Notes:

1.

AADT flows on minor roads (where traffic data is not available) have been assumed to be under 30,000 vehicles, based on measured flows for comparative roads.

Stations located near a road with at least 30,000 vehicles per day, with an annual throughput of 2000 m3 or more of petrol (2 million litres per annum) and located near sensitive receptors will require further assessment. Petrol stations with Stage 2 recovery systems do not require further consideration.

The petrol stations detailed in Table 5.2 have an authorised petrol throughput of >1000 m3. From a review of their locations, none are sited on or near a road with existing or predicted AADT flows of 30,000 vehicles and therefore do not require further assessment.

5.3.4

Fuel Storage Depots

Murco Petroleum Limited (Murco) are authorised by WBC to operate a fuel storage depot at Theale. Under Defra guidance the depot is considered to be ‘large’. In 2001 a vapour recovery unit (VRU) was installed on the site and has been operational since December 2001. The Environmental Protection Act 1990 specifies that emissions from the VRU must not exceed 35 g/m3 in any hour.

Murco monitored and reported emissions from the unit during two six-month periods in 20026. Emissions monitored during these periods indicate that average hourly emissions ranged from 3.5 g/m3 to 5.0 g/m3.

Estimated stack height data have been utilised within the screening assessment detailed in Appendix C. The emission calculations illustrate that an hourly emission rate of up to 20 g/m3 would not result in an exceedence of the annual mean objective. It is therefore considered that with the use of the VRU, emissions from the Murco site are unlikely to result in an exceedence of the AQO.
