Excavation and Flagging of Soil Absorption System

(1) Excavation for construction of a soil absorption system may be by mechanical means, provided care is taken to assure that the soil at the bottom of the excavation is not compacted or smeared. The bottom and sides of the excavation shall be level and scarified. Vehicular traffic and parking of vehicles or equipment in or on the area of the soil absorption system should be avoided at all times prior, during and after construction of the system. (2) Prior to the installation of the soil absorption system and until receipt of a Certificate of Compliance from the Approving Authority in accordance with 310 CMR 15.021, the perimeter of the soil absorption system shall be staked and flagged to identify the location of the soil absorption system and prevent the use of such area for all activities which might damage the soil absorption system. Such flagging is not intended to preclude the final grading and landscaping of the area of the soil absorption system. Stockpiling of materials or equipment within the area is prohibited.
