2.4 Environmental Standards<br />
2.4.1 Emissions to Atmosphere<br />
<strong>PDO</strong> specification SP-1005on emissions to atmosphere addresses both stationary and<br />
mobile sources and is largely based on MD 5/86 “Regulations for Air Pollution<br />
Control from Stationary Sources” and Shell Exploration and Production International<br />
best practices. These are presented below in Table 2.4.<br />
Table 2.4: Air Emission Standards<br />
Parameter<br />
Maximum Permissible Concentration<br />
Hydrogen chloride 200 mg/Nm 3<br />
Hydrogen fluoride 100 mg/Nm 3<br />
Oxides of nitrogen (as NO 2 ) 200 mg/Nm 3<br />
Phosphorus as (P 2 O 5 ) 50 mg/Nm 3<br />
Hydrogen sulphide 5 ppmv (7 mg/Nm 3 )<br />
Total particulates 100 mg/Nm 3<br />
Note: Nm 3 refers to volume at 0 o C and 1atm.<br />
In addition to the above emission limits, <strong>PDO</strong> has specified the following<br />
requirements to minimise air pollution and fugitive emissions:<br />
(a) There shall be no continuous venting of gas in new projects.<br />
(b) Fugitive emissions occurring as a result of leaks from components (such as pipe<br />
connections, valves, rotating shafts and other packed components) shall be<br />
