PART II.     EROSION AND SEDIMENTATION CONTROL MEASURES
AND ACTIVITIES.
 
2.1      General Requirements: The types of erosion and sedimentation control facilities that are incorporated into all earthmoving activities shall be those in Part 2.2 and 2.3 of this sub-chapter relating to control measures and facilities, unless the person performing the earthmoving activities provides the agency with an erosion and sedimentation control plan showing that other measures and facilities will be equally effective in preventing accelerated erosion and accelerated sedimentation.

2.2     Control Measures:
               (a)   Applicability. The provisions of this part shall apply to all earthmoving activities which have not been stabilized.

               (b)  Limited Exposed Areas. All earthmoving activities shall be planned and earned out in such a manner so as to minimize the area of disturbed land, reef, or lagoon.

               (c)  Containment of underwater sedimentation. All sedimentation resulting from underwater earthmoving activities shall be contained, confined, and restricted by the best available technology in such a manner that turbidities will be kept to a minimum.

               (d)   Velocity Control. All permanent facilities for the conveyance of water around, through; or from a project shall be designed or contain appurtenances to limit the velocity of flow in the facilities to a speed that will not cause significant erosion, and in any event to be less than 1.5 feet per second.

               (e)  Stabilization. All slopes, channels, ditches, or any disturbed area shall be stabilized as soon as possible after the final grade or final earthmoving has been completed within a section or area of a project.
                      Upon completion of the project, all areas which were disturbed by the project shall be stabilized so that accelerated erosion and accelerated sedimentation will be prevented.
 
     (f)   Containment of Fills and Reclaimed Land Within Bodies of Water, Tidal Pools or Zones, or Flood Plains or Zones. Before filling or land development within a body of water or within a tidal pool or zone or within a flood plain or zone, adequate sea walls and breakwater facilities shall be constructed to safely contain the fill without failure and to prevent accelerated sedimentation.

               (g)  Interim Stabilization. Where it is not possible to immediately install permanent stabilization facilities in a disturbed area after the final earthmoving has been completed, or where the activity ceases for more than 20 calender days, interim stabilization measures shall be promptly implemented.

               (h)  Collection of Runoff. To the maximum extent feasible, runoff from a project area shall be collected and diverted to facilities for removal of sediment.
 
               (i)   Solid Separation. Runoff from a project area shall not be discharged into the waters of Yap State without effective means to prevent sedimentation.
 
               (j)   Control Measures. Any erosion and sedimentation control facility required or necessary to protect areas for erosion during the stabilization period shall be maintained until stabilization is completed.

2.3      Control Facilities:
                (a)  Sedimentation Retention Booms. Sedimentation retention booms, as defined under 1.4 (p), shall be used to restrict accelerated sedimentation around earthmoving or earth-disturbing activities, on reefs or in lagoons in all cases, except when a finding has been made by actual demonstration that no facilities are needed to prevent accelerated sedimentation. Approval of use of alternate facilities or a finding that no facilities are necessary must be by the Agency, its Executive Officer, or other designee.
 
                (b)  Diversion Terraces.           
                      (1)   Diversion Terraces, as defined in 1.4, shall be constructed up-grade of a project area to convey runoff around the project area. They shall have sufficient capacity to convey such runoff without overflowing. For temporary diversion, the channel shall have a capacity to convey 2.0 cubic feet per second per acre of land tributary to it. For permanent diversion, the channel shall have the capacity to convey 4.0 cubic feet per second per acre to land tributary to it.
 
                     (2)  Diversion Terraces shall be grassed or lined with erosion resistant
           material to prevent accelerated erosion within the channel.
 
                     (3)  Outlet structures shall be designed to reduce discharge velocity to a level that will not cause accelerated erosion, and in any event to maintain a  discharge velocity of less than 3.0 feet per second, and shall be stabilized  before use.

                (c)   Sea wall and breakwater facilities. Sea wall and breakwaters to contain fill or reclaim land shall be sufficiently watertight to prevent accelerated sedimentation, well-constructed on a solid foundation, and to a level at least two (2) feet above the highest tide or flood level of historical knowledge, and those facilities shall be planned, designed and constructed under the direction of a person trained and experienced in building breakwater or sea wall facilities. In cases where the bottom of footings of sea wall or breakwater facilities must be placed below the level of mean low tide, the facilities shall be planned, designed and constructed under the direction of a licensed engineer trained and experienced in the building of such structures.

                (d)   Interceptor Channels.
                     (1)  Interceptor channels may be used within a project area to reduce the velocity of flow and thus prevent accelergifed erosion.

                     (2)  Water collected by interceptor channels shall be conveyed to sedimentation basins or to vegetated areas but not directly to streams.

                     (3)  Outlets to vegetated areas shall be designed to reduce the discharge velocity to a level that will not cause accelerated erosion, and in any event to maintain an outlet velocity of less than 3.0 feet per second.
 
                (e)   Channels of Conveyance. All channels used to convey water through a project area shall be designed to reduce the speed of flow of surface runoff so as not to cause accelerated erosion, and in any event to have a velocity of less than 1.5 feet per second. Where this is not possible, channels shall be grassed or lined with erosion resistant materials.

                (f)   Solid separation facilities.
          (1)  A basin for settling solids out of water shall be structurally sound and have sufficient capacity to hold the water that drains into the basin until the solids have settled out. This basin shall have a capacity of not less than 8,000 cubic feet for each acre of disturbing project area which drains into the basin.

          (2)  The basin shall be cleaned when the settling of solids has reduced its capacity by 25%.

                      (3)  Outlet structures shall be designed to allow only adequately settled water to be discharged, and at a rate that will not cause accelerated erosion. These outlet structures shall be designed to pass a minimum of 215 cubic feet per second for each acre of project area which drains into the basin.

                      (4)  The outlet structure from the sedimentation basin shall discharge into a natural waterway.

                      (5)  The sedimentation basin shall be structurally sound and protected from unauthorized acts of third parties.
 
                (g)   Hydraulic Dredging Fills.
The discharge from pumps or hydraulic dredges used to construct fills shall be sufficiently treated and retained long enough with dikes, levees, sea walls, or other structures so that accelerated sedimentation will not take place in the waters of Yap State which receive the effluent. Transmission pipelines transporting fill material will be maintained in a watertight condition at all times during excavation and fill operation.

               (h)  Ocean-going Barges Scows or Vessels for Hauling Dredged Soil.
Such vessels operating in waters of Yap State will be sufficiently tight and secure that accelerated sedimentation will not occur by reason of leaking or premature dumping due to faulty mechanisms.
