(1) Excavations for borrow, clay, topsoil or silt.
A natural buffer strip at least 50 feet wide must be maintained between any excavation and any property boundary. A natural buffer strip at least 25 feet wide must be maintained between any topsoil excavation and a property boundary. These distances may be reduced to not less than 10 feet with the written permission of the affected property owner or owners, except that the distance may not be reduced to less than 25 feet from the boundary of a cemetery or burial ground. The buffer strip between excavations owned by abutting owners may be eliminated with the abutter's written permission, provided the elimination of this buffer strip does not increase the runoff from either excavation across the property boundary. Any written permission to reduce a buffer must provide that it remains in effect until mining ceases and must be recorded in the registry of deeds. All property boundaries must be identified in the field by markings such as metal posts, stakes, flagging or blazed trees.

(2) Quarries.
A natural buffer strip at least 100 feet wide must be maintained between any excavation and any property boundary. These distances may be reduced to not less than 10 feet with the written permission of the affected property owner or owners, except that the distance may not be reduced to less than 25 feet from the boundary of a cemetery or burial ground. The buffer strip between excavations owned by abutting owners may be eliminated with the abutter's written permission, provided the elimination of this buffer strip does not increase the runoff from either excavation across the property boundary. Any written permission to reduce a buffer must provide that it remains in effect until mining ceases and must be recorded in the registry of deeds. All property boundaries must be identified in the field by markings such as metal posts, stakes, flagging or blazed trees.
