FAILURE TO TAKE ADEQUATE ACTION IN RESPONSE TO THIS NOTICE COULD RESULT IN SERIOUS LEGAL CONSEQUENCES. An inspection of your facility on August 24, 2000 by the Northampton Department of Public Works personnel revealed one or more "cross connections" to the public water supply, which are in non-compliance with the Federal Safe Drinking Water Act of 1974 (Public Law 93-523) and the Commonwealth of Massachusetts, Department of Environmental Protection Drinking Water Regulations, 310 CMR 22.22. A "cross connection" is an unprotected actual or potential connection between the public or potable water system and any other source or system which is unapproved for consumption purposes. A cross connection can also be considered as any by-pass arrangement, jumper connection, removable section, swivel or change-over device and other temporary or permanent device through which "backflow" or "backflow siphonage" can or may occur. The violation of CMR 22.22 found by the inspectors as a result of the survey are listed on Attachment "A".

Being delegated by the State, plans and specifications indicating the method of protection must be approved by the City of Northampton Department of Public Works and Plumbing Inspector 2Et • prior to construction of installation. Refer to the Northampton Department of Public Works policy on cross connections in regard to submittal data. If you fail to take the requested action by the prescribed deadline, you could be subject to legal action, including but not limited to, termination of your water service, court imposed civil penalties or civil administrative penalties assessed by the Department of Environmental Protection.

Acting Director of Public Works cc: plumbing inspector c:\water service\northampton\noncompliance\dr.fadc • ATTACHMENT "A" The following locations are the locations of the cross connections found at this facility: 1. Water Main Entrance: This facility must have a containment backflow device installed. A Reduced Pressure Zone Backflow Preventer (RPZ) must be installed at the water main entrance after the meter. The location of this device should be elevated high enough to allow for relief valve drainage through air gapped drain to outside. No floor drain or indirect waste is available in this area. 2. Lower Level, Dr. Levinson's Area: A. The two chair water supplies must have, at a minimum, a dual check backflow preventer, Watts #7 or equal. B. The Dent-x 810 X-ray processor water supply must have a RPZ installed to provide proper protection. Proper height for drainage to waste must be considered. C. The Foster Model Trimmer water supply must have an in-line backflow preventer, Watts #N9 or equal installed to provide protection. D. Modern Image Salon: The two salon sinks must have dual check backflow preventers, Watts #7 or equal installed in the supply to the spray hose connections. 3. Upper Level, Dental Offices: A. Dental Chairs: The new water supply lines to the proposed eight dental chairs must have an RPZ installed on the main line supplying all the chairs and before any other water connections. This device should be located near the water main device for proper testing location and drainage. B. Dental Chairs Continued: All eight dental chairs must have at each chair a dual check device, Watts #7 or equal to provide proper protection. C. X-Ray Photo Processor: The water supply to this processor must have an RPZ installed at the proper height and have drainage provided. D. Suction Equipment: The suction equipment at this facility has no water use, and no protection required. Note: All Reduced Pressure Zone Backflow Preventers have relief valves.

The Entire Facility: All sinks with threaded outlets not protected by atmospheric vacuum breakers, sill cocks, taps, draw-offs, etc., must be equipped with hose bib type vacuum breakers, so that hoses will not become unprotected cross connections (anti-siphon device). ****SPECIAL CAUTION**** THERMAL EXPANSION_- When water is heated and stored in a consumer's water system or a branch of the system that has been closed by the installation of a backflow prevention device or any other checking device, an auxiliary relief valve, or expansion chamber, shall be installed to limit thermal expansion of the water being heated to not more than 80 psi static (no flow) pressure at any fixture on the system. 0oP17yPt.\ ,._„t, CITY OF NORTHAMPTON, MASSACHUSETTS DEPARTMENT OF PUBLIC WORKS , 125 Locust Street -�- Northampton, MA 01060 413-587-1570 Samuel B.
