GENERAL STANDARD FOR SOIL POLLUTION CONTROL استاندارد كنترل آلودگي خاك
Cleaning up hydrocarbon based liquids and refined products release from pipelines,oil production units, Desalter plants, pumping Station, Tank farms and drilling operation in upstream part and other pollutants from oil and petrochemical refineries and above ground/ under ground storage tanks in down stream part of OGP industries,
Cleaning up hydrocarbon based liquids and refined products release from pipelines,oil production units, Desalter plants, pumping Station, Tank farms and drilling operation in upstream part and other pollutants from oil and petrochemical refineries and above ground/ under ground storage tanks in down stream part of OGP industries, typically involves using several corrective actions and strategies. Short term emergency measures may involves imminent actions to control acute safety and health hazards such as potential explosions and toxications. After the imminent danger has been eliminated, longer term corrective actions involve cleaning up pollutants that have entered the surface and subsurface environment.
Petroleum products in the subsurface may be trapped between soil particles in the unsaturated zone, floating on the water table or dissolved in ground water in the saturated zone. The focus of this standard is on long-term strategies for cleaning up petroleum products in unsaturated or saturated zones. When the spill occurs some kind of soil clean up is typically necessary.
In this Standard the following matter of soil pollution control is discussed:
a) To provide authorities concerned on how to assess site conditions in the unsaturated zone and where a petroleum product release has occurred, information needed to localized where in the unsaturated zone petroleum product is located, and also the removal of petroleum products from the unsaturated zone at a given site.
b) To assess on the technologies designed specifically for clean-up of the saturated zone.
c) To provide a structural methodology for evaluation and potential consequences of a leak in a pipeline. The methodology that is intended to assist pipeline operators in assessing the need to install pipeline leak detection facilities, and an overview of available pipeline leak detection techniques.
d) The requirements of Islamic Republic of Iran Environmental Department for soil pollution prevention shall be considered in engineering design and site selection of OGP facilities. Under no circumstances soil pollutants elements shall exceed the determined rates in this standard.
The Standard is classified into three sections as follows:
Section I: Unsaturated Zone
Section II: Saturated Zone
Section III: Pipeline Leak Detection
