FOR DETAIL REGARDING SLOLPE AND RETURN TO GRADE SEE "CROSS SECTION OF LEACHING TRENCHES (BED)" DETAIL. EXCAVATOR MUST PROVIDE, A SWALE 5 FEET WIDE AROUND SAS TO PREVENT SURFACE WATER RUNOFF FROM DRAINING ON TO NEIGHBORING PROPERTY. IF LEDGE IS ENCOUNTERED HIGHER THAN ANTICIPATED OR HIGHER THAN OBSERVED DURING THE EVALUATION OF DEEP OBSERVATION HOLES (FERC TEST), FILL MUST BE ADDED TO RAISE THE BOTTOM OF THE LEACHING SYSTEM AT LEAST 4 FEET ABOVE THE HIGHEST ELEVATION OF LEDGE FOUND. ANY PART OF THE SEPTIC SYSTEM THAT WILL BE SUBJECT TO VEHICULAR TRAFFIC MUST HAVE AN H 20 WHEEL LOAD RATING. NO WELLS OBSERVED WITHIN 150' OF PROPOSED LEACHING SYSTEM OTHER THAN SHOWN. PROPERTY OWNER IS RESPONSIBLE FOR COMPLIANCE WITH ALL Lr-`CAL ZONING REGULATIONS, CONSERVATION COMMISSION REGULATINGS AND MASSACHUSETTS IVETLA ND PROTECTION ACT..

BECAUSE OF SMEARING IN TIIE "C" HORIZON INSTALLATION OF THE LEACHING SYSTEM CANNOT TAKE PLACE DURING THE WET SEASON WHEN THE EXCAVATION CAN BE SMEARED. THE STONE CANNOT TIE PUT INTO THE TRENCHES OR INTO THE BETS UNTIL THE SIDE WALLS AND THE BOTTOM HAVE BFFIN RAKED AND ROUGHENED UP. PROPERTY LINES MUST BE ESi ABLISIIED BY A REGISTERED LAND SURVEYOR IN ORDER TO MAINTAIN PROPER SETBAC L NO DRIVEWAY, PARKING AREA OR OTHER IMPERVIOUS SURFACE SMALL BE LOCATED ABOVE THE LEACHING SYSTEM EXCEPT WHERE UNAVOIDABLE IPI SUCH CASES VENTING MUST BE PRESENT. ANY WORK DONE BY THE PRNPERTY OWNER LESS THAN 100' FROM A WETLAND WILL REQUIRE THAT HE FILE A NOTICE OF INTENT WITH THE LOCAL CONSERVATION COMMISSION. NO SEPTIC SYSTRM ADDITrvSS MAY BE PLACED IN A SEPTIC TANK, NO PART OF A LEACHING SYSTEM MAY BE LOCATED LESS THAN 100 FEET FROM ANY WELL OR EDGE OF A WETLAND OR LESS THAN 10 FEET FROM ANY PROPER'L'Y LINE. PROPERTY OWNER IS RESPONSIBLE FOR FINISH GRADING AND SEEDING. EXCAVATOR IS RESPONSIBLE FOR BACKFILLING AND ROUGH GRADING UNLESS OTHERWISE NEGOTIATED WITH PROPERTY OWNER. THIS SEPTIC SYSTEM DESIGN IS NOT INTENDED TO BE A SITE PLAN. EXCAVATOR MUST CALL DIG SAFE FOR CLEARANCE BEFORE STARTING WORK TEL: 18" 3447233. DO NOT SCALE DRAWING. THE DESIGN ENGINEER MUST INSPECT ALL COMPONENTS OF THE SUBSURFACE ABSORPTION SYSTEM PRIOR TO BACKFILLING. 15.021(3) TEL: 413 467-7228 PLEASE ALLOW 24 - 48 HOURS NOTICE `;-,YAS=D S TONT -i "i i.EAIN STOMA. THE MASSACHUSETTS DEP HAS ESTABLISHED A TEST TO DETERMINE THE CLEANLINESS OF "WASHED STONE" USED IN THE LEACHING SYSTEM. MARK A S GALLON WHITE PLASTIC BUCKET AT THE 1 GALLON HEIGHT AND THE 4 GALLON HEIGHT. PLACE STONE FROM THE PILE OR TRUCK IN THE BUCKET UP TO THE 1 GALLON MARK. MAKE SURE THAT STONE COMES FROM SEVERAL DIFFERENT PLACES IN THE TRUCK OR PILE. FILL THE BUCKET TO THE 4 GALLON MARK WITH CLEAN WATER, AGITATE THE STONE - WATER MIXTURE TO SUSPEND ANY FINE PARTICLES. WAIT 60 SECONDS. AFTER 60 SECONDS IF THE OUTLINES OF THE INDIVIDUAL PIECES OF STONE ARE CLEARLY VISIBLE THE STONE CAN BE ASSUMED TO BE REASONABLY FREE OF FINES. IF THE INDIVIDUAL STONE PIECES CANNOT BE CLEARLY SEEN THE STONE IS PROBABLY TOO "DIRTY" AND SHOULD NOT BE USED IN A TITLE S SOH, ABSORPTION SYSTEM. IF SUCH STONE IS USED THE SYSTEM WILL BE REJECTED.
