MINISTERIAL ORDER NO.2 OF 2001 WITH RESPECT TO AMENDING CERTAIN PROVISIONS OF ORDER NO.10 OF 1999 WITH RESPECT TO ENVIRONMENTAL STANDARDS (AIR AND WATER) The Minister of Municipalities and Environmental Affairs, having examined Legislative Decree No.21 of 1996 with respect to the Environment, as amended by Legislative Decree No. 8 of 1997, and Decree No.14 of 2001 with respect to Ministerial Appointments, and Ministerial Order No.10 of 1999 with respect to Environmental Standards (Air and Water), and upon the submission of the Director General of Environmental Affairs, HEREBY ORDERS: Article 1 For the provisions of Article (1) of Ministerial Order No.10 of 1999 with respect to the Environmental Standards (Air and Water) there shall be added Paragraphs (M and N) as follows: (M) Territorial Waters: They shall mean the areas of sea which follow the coastal waters of the State of Bahrain and extend towards the sea for an area of 12 nautical miles measuring from the base line which is measured from the width of the territorial waters in accordance with the provisions of the United Nations Treaty of the Law of the Sea of 1982. (N) Exclusive Economic Area: Article 2 It shall mean the marine area that extends beyond the territorial waters for an area of two hundred nautical miles measured by the base line. The provisions of Paragraphs (I, J and K) of Article (1) of Order No.10 of 1999 with respect to Environmental Standards (Air and Water) shall be amended as follows: (I) RECEIVING WATERS They shall be the coastal waters of the State with a depth of its territorial waters and their exclusive economic area, which extends beyond the territorial waters and in which hazardous or contaminated materials are voluntarily or involuntarily, directly or indirectly discharged and contain the following:

(1) Mixing Area: It shall mean the water receiving area adjacent to the discharge point and extends around or beyond it for a circular or semi-circular area with a diameter of (100) metres, increases or decreases than that according to the discharge point of the location, type and characteristics of the discharged waste water. In this area the primary concentration reduction of such water in a natural form whether certain changes occur or excesses arise in the quality of receiving water or in the measurements of this quality or does not take effect provided the temperature of the receiving water shall not exceed or fall at the touching point with the outside boundaries of the mixing area in all cases below 3 degrees Celsius (+ or 3 0 ) compared to seawater temperature, unless sensitive environmental systems are placed in that area as estimated by the Environmental Authority. (2) Discharge Point It shall mean the meeting point of the waste water with the received water at the centre of a circle or the middle of the mixing area. (J) WASTE WATER: Any contaminated water having a pollutant environmental effect resulting from industrial, chemical or radioactive operations and having an environmental pollution effect and whether these waters were or were not discharged in the receiving water. (K) DISCHARGING: It shall mean the direct or indirect dumping, leaking, emission, pumping, discharging or spilling of any hazardous and contaminated substances or disposal thereof in the surrounding air or the receiving water and is voluntary or involuntary, directly or indirectly discharged and subject to the substance levels determined in Tables No. (3 and 4). Article 3 For the provisions of Articles (13 and 24) of Order No. 10 of 1999 with respect to Environmental Standards (Air and Water) there shall be substituted the following: Article (13) Upon using boilers using fossil fuels (oil or gas), furnaces, power generating units, the specifications of fuel used and the concentrations of harmful gases and fumes resulting from the fuel burning in these boilers, furnaces and units shall be within the permitted limits listed in Schedule (3) which is attached to this Order. In all cases, the boilers should be cleaned and gases removed from them using amino washers or any other operation by another suitable equipment approved by the Environment Authority. Suitable air cleaners approved by the Environment Authority should be used to limit the quantity of leaking gases and particles. Article (24) The Environmental Authority may, upon a request from the concerned party, approve an extension of the fixed period to modify the status for another period if such matter requires action if it was apparent to the Environment Authority that the measures adopted for the purpose of implementing the provisions of this Order were serious. The parties concerned shall submit applications for extension to the Environment Authority

six months prior to the expiry of the three year period indicated in the previous Article, provided that the application shall contain the justifications for such extension and the procedures adopted to implement this Order. Article 4 For the provisions of Ministerial Order No.10 of 1999 with respect to Environmental Standards (Air and Water), there shall be added a new Article under No. (22 bis) which follows Article (22) to read as follows: Article 22 (bis) The Environment Authority may define the mixing area of certain projects with more or less than a circle or semi-circle with a diameter of one hundred (100) metres, as the case may be, and in view of the location, type and characteristics of the discharged waste water. The Environment Authority may compel the projects which do not accept such definition or wishes to modify their mixing area or have been defined before, to carry out such task and at their own expenses to conduct a study or more by a specialized firm of consultants approved by the Environment Authority to define the mixing point for such projects and determine the effect of discharging the waste water on such area. The definition resulting from this study shall be final. Article 5 The following chemical compounds and particles shall be added to the group of chemical compounds and particles indicated in Addendum No.(1) to determine the Group of Air Quality Indicators attached to Order No.10 of 1999 with respect to Environmental Standards (Air and Water), under No.(5). (5) Carbon Monoxide (Co): Article 6 A gas that has no colour, taste or odor and results from the incomplete burning of carbons. It forms a stable compound when united with the haemoglobin in the blood and is considered as a poisonous gas if it exists in quantities, which exceed the permitted level. For Tables No. (3) related to the Maximum Limits of Certain Gases and Fumes Leaking when Burning Fuel and No. (4) related to the Measurement of Materials Discharged in the Air from certain Industries, which are attached to Order No. 10 of 1999 with respect to Environmental Standards (Air and Water), there shall be substituted Table No. (3) which is attached to this Order. The serial numbers of the Tables indicated in the Articles of the aforesaid Order shall be amended accordingly. Article 7 For Table No. (5) concerning Standards for Water Discharged from Factories attached to Order No. 10 of 1999 with respect to Environmental Standards (Air and Water), there shall be substituted Table No. (4) which is attached to this Order. The serial number of Tables indicated in the Articles of the said Order shall be amended accordingly. Article 8

The Director General of Environment Affairs shall implement this Order, which shall come into effect from the date of its publication in the Official Gazette. Affairs.
