Saudi Aramco, Saudi Arabia's national oil company, has issued a report on its program for preservation of the environment, including its plan to completely eliminate lead from gasoline. It has already reduced this by half. Saudi Aramco is considered a global pioneer in demonstrating concern to protect and preserve the environment, having initiated a plan for environmental awareness as early as 1963. The company now has plans that include health regulations, contingencies for oil leaks, guidelines for disposal of hazardous materials, and standards for air quality. Saudi Aramco currently operates, in addition to fifteen for meteorology only, ten meteorological stations which monitor air quality, checking for airborne ore particles and emissions of pollutants such as carbon dioxide, carbon monoxide, nitrogen oxide, and hydrogen sulfite. The report indicated that air quality in the Eastern Province has greatly improved following the establishment of the main gas network which reduced the need to flare associated gas at wellheads. Saudi Aramco is currently extracting over 3,500 tons of natural sulfur per day from the gas associated with crude oil. The program also enables the company to anticipate the extent of the impact of any new project on air quality so that it can take measures to avert such problems right from the preliminary design phase.
