Dear Mr. Kavanaugh:

to have it brought to,within "'of finished� grad
2. The soil absorption system being replaced consists of a plastic,chamber leaching system.
Those components often have a smaller footprint than the stone--and.-pipe system being,
proposed. The design is proposing t -use the barrier and 5 over&g sand that,is
curriently in, the ground. Examine the design plan or,the existing physical system
components to determine if the size off"the proposed stone-arid-pipe field will allow the
barrier and overdig to rem be-re-used
3. The existing im p en-neable bawler is proposed to be re-us,ed around the soil absorption
system. Confirm the elevation of the top of the barrier complies with the design
requirements for the stone-and-pipe Feld being proposed, and the bottom elevation is at
an elevation that complies with,the design requirements 310 C R 15.255)
,. Two dates are provided for the soil and percolation testing. Municipal records show
these were both completed,on July 31, 20,07

requirements in the,North Andover regulations and is not coincident with the Sete

pursuant to CMR 15.240., This is due to the reduced,oxygen.transfer which has been
demonstrate d,to exist in the center of a leach field. You may wish.to take this into
a� ideratlon in the desing of this replacement soil absorption system.
