EXISTING U11LITIES WHERE SHOWN IN THE DRAWINGS ARE APPROXIMATE. THE CONTRACTOR SHALL BE RESPON- SIBLE FOR PROPERLY LOCATING AND COORDINATING THE PROPOSED CON- STRUC11ON ACTIVITY WITH DIG -SAFE AND THE APPLICABLE UTILITY COMPANY AND MAINTAINING THE EXISTING UTILTY SYSTEM IN SERVICE. DIG -SAFE SHALL BE NOTIFIED PER THE STATE OF MASSACHUSETTS STATUTE CHAPTER 82, SECTION 409 AT TEL. 1-888-344-7233. THE ENGINEER DOES NOT GUARANTEE THEIR ACCURACY OR THAT ALL UTILITIES AND SUBSURFACE STRUCTURES ARE SHOWN. LOCATIONS AND ELEVATIONS OF UNDERGROUND UTILITIES TAKEN FROM RECORD PLANS. THE CONTRACTOR SHALL VERIFY SIZE, LOCATION AND INVERTS OF UTILITIES AND STRUCTURES AS REQUIRED PRIOR TO THE START OF CONSTRUCTION. 8. THIS SYSTEM IS NOT DESIGNED FOR THE USE OF A GARBAGE GRINDER. A GARBAGE GRINDER IS NOT RECOMMENDED DUE TO RECOGNIZED ADVERSE IMPACTS TO THE LEACHING FACILITY. 9. EXITING INVERTS ARE TO BE CHECKED BY THE CONTRACTOR PRIOR TO CONSTRUCTION 10.
