B 910 SCHEDULE ill STANDARDS FOR DESIGN OF f ACILITJES (1) Sediment trap shall retain gravel and sand which shall ensure evacuation of all the fine sand, silt and shale fractions. (2) Residual water and sediment evacuation conduit shall provide the residual water downstream of the reservoir and sediments shall be evacuated, mainly during flood situations, without transition through the main reservoir and with a minimum damage to the riverine ecosystem. (3) Water supply to the main reservoir shall be fed by a conduit that starts in the surface waters of the water trap, without any gravel or coarse and medium sand. (4) The main reservoir shall be selected so that the final deep basin is characterized by simple biological structure and a short basin axis, to facilitate flushing of the basin sediments. (5) Bottom outlet of the dam shaU be used, if necessary, in combination with other passive and/or active measures to evacuate fine sediments from the deep basin by flushing operations. (6) Fish ladder shall be constructed around or on the dam to facilitate migration of fish between fresh and salt water. (7) Main conduit for hydroelectric or other reservoir use shall be maintained. SCHEDULE N MAINTENANCE OF f ACILITIES [Regulations 8 (6); 11 (b)] (1) Maintenance of a high hazard dam or significant hazard dam, except for certain cutting or removal of trees, does not require an approval from the Agency. (2) To be exempt from Agency approval, the cutting or removal of trees must be limited to those trees with a diameter less than 6 inches (measured 0.6 metres above the ground level) or that does not affect the integrity of the dam. (3) If trees have a diameter greater than 6 inches (measured 0.6 metres above the ground level) then the dam owner shall first consult with a qualified engineer who will determine if the cutting or removal could jeopardize the integrity of the dam. ( 4) The owner shall obtain a written report from the qualified Engineer, if the qualified Engineer determines that the cutting or removal is not a threat to the integrity of the dam, and keep a copy of the report in file. (5) The report does not have to be filed with the Agency. The owner shall file an application for repair of the dam in accordance with these Regulations if the qualified Engineer detem1ines that the cutting or removal is a threat to the integrity of the dam. (6) Mowing or cutting of vegetation shall be performed without an approval from the Appropriate Authority provided it is limited to areas on the dam and adjacent to the dam such that an area does not exceed five (5) metres from the embankment, spi II way or low level control structure. (7) All other mowing or cutting of vegetation within freshwater wetlands will require a permit from the appropriate authority unless specifically exempted under the National Environmental (Wetlands, River Banks and Lake Shores Protection) Regulations, 2009. (8) Areas exceeding five (5) metres from the embankment, spiUway or low level control structure that have been historically mowed and maintained are specifically exempted. These areas can continue to be mowed without a permit from the Agency. (9) All maintenance activities shall comply with the following (a) best management practices for erosion and sediment controls shall be used. All controls must be maintained in effective operating condition during the activity, and all exposed soi.I and other fills must be permanently stabilized at the earliest possible date; (b) all equipment used for maintenance activities shall be removed from any freshwater wetland upon completion of the maintenance project; and B 911 . B 912 (c) all repair and maintenance activities shall be protective of water quality and freshwater wetland functions and values so as to prevent pollutants, sediment, direct discharge of storm water run off, or any materia I foreign to waters including freshwater wetlands, or hazardous to life, from entering any waters including freshwater wetlands. SCHEDULE V GumELINES FOR REGULATING DrSTR.ESSED FACILITY [Regulation 11 ] (1) Whenever the appropriate authorities determine that a dam is distressed, it shall determine whether the water in the reservoir shall be drawn off in whole or in part, and the actions necessa1y to make the dam safe. (2) The Agency may notify the owner or person maintaining or having control of the dam, by certified mail, that the dam is unsafe, the actions necessary to make the dam safe and a schedule to complete the actions. (3) The Agency may notify the owner or person maintaining or having control of the dam, by certified mail that the dam is distressed after completing the inspection or after receiving an inspection report completed by a qua I ified Engineer. ( 4) The Agency may issue an immediate compliance order stating the existence of the unsafe condition and the action deemed necessary to correct the unsafe condition. It shall order the water in the reservoir to be drawn off, in whole or in part. The immediate compliance order shall become effective immediately upon service or within such time as is specified by the Agency in such order. (5) Any emergency action taken by the Owner of the facility shall immediately be reported to the Agency and the Local Government(s) in which the facility is located The facility shall also report, by telephone within twenty­ four (24) hours and in writing within three (3) days, the emergency action taken. (6) If water has been drawn off or the dam has been altered pursuant to an order by the Agency, the reservoir shall not be refilled without approval of the Agency. (7) If the Owner of the faci Ii ty fails to comply with an order, the Agency may also, by summons and complaint, seek to enforce the order in a court of competent jurisdiction. B 913 B 914 SCHEDULE VI ENFORCEMENT ACTIONS [Regulation 19 (I )] (l)As set forth by Section 8 of the National Environmental Standards and Regulations Enforcement Agency (NESREA)Act 2007, the Agency may have the power to issue enforcement notices, orders, administrative penalties or other requirements to ensure compliance with these Regulations. (2) The Agency may also provide written or verbal warning of its intent to undertake enforcement action. Nothing in these Regulations shall limit the authority of the Attorney General of the Federation to prosecute offenders as required by law. (3) The Agency may forward a copy of the enforcement notices and/or orders to recognized court of law in accordance with the laws of the land and the State Government wherein the dam is located. SCHEDULE VII DAM CLASSIFICATION [Regularfon 4 (!)] (I )All dams and reservoirs subjecttothese Regulations shall be classified according to their size and hazard potential. Classifications shall be made in accordance with this section and are subject to final approval by the appropriate authority. It may be necessary to reclassify dams as additional information becomes available. (2) The classification for size is based on the height of tJ1e dam and storage capacity. Size classification may be determined by either storage or height, whichever gives the larger size capacity as specified under the FGN (2007) Compendium ofNigerian Dams. (3) The classification for potential hazard shall be in accordance with the magnitude of the loss of life and damage to property. The hazards pertain to potential loss of human life or property damage in the event of fai I ure or improper operation of the dam or appurtenant works. Probable future development of the area downstream from the darn that would be affected by its failure shall be considered in detennining the classification. Dams shal I be subject to reclassification if the appropriate authorities determine that the hazard has changed. (4)(a)HighHazard(Class !}-Dams located where failure will likely cause loss of life or serious damage to property, industrial and commercial facilities, important public utilities, main highways orrailroads. (b) Signijicanr Hazard (Class 11)-Dams located where failure will not likely cause lossoflife but may damage property, industrial and commercial facilities, secondaiy highways or railroad(s) or cause interruption of use or service of relatively important public utilities. ( c) Low Hazard ( Class IIJ)-Dams located where failure may cause minimal property damage, loss of life is not expected. (5) Currently, there is inadequate infonnation to classify the existing dams and reservoirs in the country according to the above classifications. Consequently, the classifications of the reservoirs (by size) according to the Compendium of Dams in Nigeria (FGN, 2007) are adopted in the interim. The 179 dams in Nigeria are listed in the following tables according to the adopted classifications. Large is I 09, Medium is 1 7 and Small is 53. B 915 General. Size Classification.
