Section 096-420-12 - Septage Storage Facility Design and ConstructionSeptage storage facilities must meet the following design and construction requirements:
A. Construction Material. Facilities must be constructed of impermeable materials such as steel, fiberglass or coated-concrete which are suitable for the intended use and which will have minimal deterioration over time. Construction material must be adequate to prevent any leakage of septage. Any corrodible materials, such as steel, must be properly prepared to prevent corrosion.B.Septage Screening/Stabilization. If screening and stabilization, such as alkaline stabilization, is to occur within the storage facility, then screening and stabilization equipment must be included in the facility design.C.Spill and Leachate Containment. The facility must be designed to contain any septage spills caused by failure of the storage facility, contain any leachate generated from the storage facility and contain any leakage from septage conveyances.D. Monitoring. Facilities must provide for detection of any subsurface leaks which may occur from the storage facility.E.Fill and Grading. Fill material surrounding the facility must be suitable for the intended use and must be graded to allow for proper drainage away from the facility.F.Erosion Control. The "Maine Erosion and Sediment Control Handbook for Construction" Best Management Practices (1991), which is hereby incorporated by reference, must be followed during all phases of construction to prevent erosion and sedimentation.G.Access Control. Access to the storage facility must be controlled by the following: (1) Cover. All access ports to a storage facility must be covered to prevent unauthorized access. Covers must be locked when the facility is not actively being used for unloading or loading septage.(2) Signs. Legible signs must be posted at the site access. Signs must read as follows: "Notice - Septage Storage Area - Access Prohibited" or similar wording. Lettering on signs must be a minimum of two (2) inches in height. The top of the signs must be between four (4) feet and eight (8) feet above the ground surface.H.Traffic. The following design criteria must be met for all access roads to the site: (1) On-site roads must be suitable for movement of traffic within the facility.(2) Sight distances at entrances to the facility must be suitable, as determined by one of the following: (a) The sight distance to the entrance of the facility is equal to or greater than a foot value of ten (10) times the speed limit. Measurements are to be taken from the road entrance, ten (10) feet behind the edge of the shoulder and 42" off the ground, to a point down the road shoulder, 51" above the pavement; or(b) The Department of Transportation has issued a site entrance permit for the access road; or(c) The local highway department has issued a site entrance permit for the access road.06- 096 C.M.R. ch. 420, § 12
