LIMITED SERVICE HEALTH CLINICS THE DEPARTMENT OF PUBLIC HEALTH HAS RECENTLY PROMUL- GATED REGULATIONS CREATING A TYPE OF CLINIC KNOWN AS “LIMITED SERVICES” CLINICS, WHICH WOULD BE PLACED INSIDE RETAIL STORES. PURSUANT TO 248 CMR 10.10 (18) (table 1). THE ADDITION OF A “LIMITED SERVICES” CLINIC WILL CHANGE THE PLUMBING USE GROUP OF A RETAIL STORE TO THAT OF A MEDICAL HEALTH CARE BUILDING. DUE TO THE UNIQUE NATURE OF THESE FACILITIES, THE BOARD OF STATE EXAMINERS OF PLUMBERS AND GAS FITTERS HAS VOTED TODAY TO ADOPT THE FOLLOWING GUIDE- LINES TO WAIVE A SMALL NUMBER OF REQUIREMENTS IN THE PLUMB -ING CODE WHICH THE BOARD HAS DEEMED UNNECESSARY FOR THE UNIQUE NATURE OF THOSE FACILITIES PG 6

Slide 11: 

POLICY PER G.L. C. 142 & 13,THE BOARD IS CHARGED WITH ADOPTING REGULATIONS REGARDING THE “CONSTRUCTION, ALTERATIONS, REPAIR & “ INSPECTION OF PLUMBING” IN ALL CITIES & TOWNS.

HYDROMECHANICAL GREASE INTERCEPTORS CONTINOUSLY SEPARATE THE FOG AT THE VELOCITY IT ENTERS THE INTERCEPTOR. EXTERNAL GRAVITY DESIGN TYPE INCOR – PORATES TWO OR MORE COMPARTMENTS IN SERIES, A MINIMUM VOLUME OF 300 GLS. AND USES ITS LARGE VOLUME OF WATER TO SLOW THE FLOW VELOCITY DOWN ALL – OWING THE TIME REQUIRED FOR THE BUOY - ANCY OF GREASE IN THE WATER TO CAUSE SEPARATION.

EMPLOYER CERTIFICATION OF APPLICANT HOURS IN GENERAL, EMPLOYERS MUST BE ABLE TO PROVIDE SOCIAL SECURITY RECORDS FOR THEIR EMPLOYEES WHEN THOSE EMPLOYEES SEEK A LICENSE. HOWEVER, THE BOARD HAS NOTED THAT CERTAIN INDIVIDUALS ARE UNABLE TO PRODUCE THOSE RECORDS AND HAS CHECKED “NO” ON THE RELEVANT FORM. THESE RECORDS ARE NECESSARY FOR THE BOARD AS THEY SHOW A SUPERVISORY EMPLOYMENT RELATIONSHIP GENERALLY NECES- SARY FOR AN APPRENTICESHIP. WHEN SUCH A SITUATION TAKES PLACE, THE FORM SHALL BE DEEMED TO BE INCOMPLETE AND THE FOLLOWING POLICY APPLIES: A CERTIFICATION BY THE SUPERVISING MASTER PLUMBER/GAS- FITTER, UNDER PAINS AND PENALTIES OF PERJURY, THAT THE APPLICANT WAS NOT PAID FOR THE TIME THAT THEY WORKED. A COPY OF THE CONTRACT BETWEEN THE MASTER AND THE APPLICANT SHOWING AN AGREEMENT THAT THE WORK WAS UNPAID. PG 42

Slide 47:

IN THE EVENT THE MASTER DOES NOT CORRECT THE 1099 ISSUE AND BECOME ABLE TO PROVIDE SOCIAL SECURITY RECORDS, THEY MUST FILL IN AN AFFIDAVIT APPROVED BY THE BOARD REGARD- ING THE APPLICANT’S EMPLOYMENT. IN THIS INSTANCE THE EMPLOYER MAY ALSO BE REQUIRED TO APPEAR BEFORE THE BOARD. EMPLOYER CERTIFICATION OF APPLICANT HOURS CON. PG 43

Slide 48: 

IT IS THE OBLIGATION OF ALL MASTERS TO ADHERE TO THIS POLICY WHEN THEY AGREE TO TAKE ON AN APPRENTICE. FAILURE TO ADHERE TO THESE PROVISIONS CONSTITUTES UNPROFESSIONAL CONDUCT AND MAY SUBJECT THE MASTER TO DISCIPLINARY ACTION. AS THE APPLICATION IS CONSIDERED INCOMPLETE WITHOUT ADHERENCE TO THIS POLICY, AN APPLI- CANT MAY BE SUBJECT TO HAVING THEIR APPLICATION BEING RETURNED AS INCOMPLETE. SUCH AN APPLICANT MAY CHOOSE TO FILE A COMPLAINT AGAINST THE MASTER. IF SUCH A COM- PLAINT HAS BEEN FILED, THE BOARD WOULD HAVE JUSTIFICA- TION FOR GRANTING THE APPLICATION AN APPEARANCE BEFORE THE BOARD. THE BOARD MAY THEN BE WILLING TO CONSIDER ADDITIONAL EVIDENCE BY THE APPLICANT DEMONSTRATING THAT ALL LAWS AND REGULATIONS HAVE BEEN ADHERED TO AND THAT THE APPLICANT HAS ACCRUED THE REQUIRED EXPERIENCE FOR THE LICENSE SOUGHT. EMPLOYER CERTIFICATIONS OF APPLICANT HOURS CON. PG 44

Slide 50: 

WHAT IS GRAY WATER? ANY WASTE WATER GENERATED IN THE HOME, EXCEPT WATER FROM TOILETS IS CALLED GRAY WATER. DISH, SHOWER, SINK AND LAUNDRY GRAY WATER COMPRISE 50 TO 80% OF RESIDENTIAL WASTE WATER. GRAY WATER MAY BE REUSED FOR OTHER PURPOSES ESPECIALLY LANDSCAPE AND IRRIGATION. WHAT CAN YOU DO WITH GRAY WATER? WHY USE GRAY WATER? IT IS SAID THAT THERE IS NO SUCH THING AS WASTE, JUST MISPLACED RESOURCES. GRAY WATER SYSTEMS TURN WASTE WATER AND ITS NUTRIENTS INTO USEFUL RESOURCES. CONVENTIONAL PLUMBING SYSTEMS DISPOSE OF GRAY WATER VIA. SEPTIC TANKS OR SEWERS. THE MANY DRAWBACKS OF THIS PRACTICE INCLUDES OVERLOADING TREATMENT SYSTEMS, CONTAMINATING NATURAL WATERS WITH POORLY TREATED EFFLUENT. PG 46

Slide 51: 

GRAY WATER SYSTEM REQUIREMENTS ALL GRAY WATER SYSTEMS SHALL REQUIRE BOARD APPROVAL. IF THE GRAY WATER SYSTEM IS CONNECTED WITH A POTABLE WATER SYSTEM, IT SHALL BE PRO – TECTED WITH A HIGH HAZARD BACK FLOW DEVICE OR PROPERLY AIR GAPPED. ALL PIPING SHALL BE COLOR MARKED BY PAINTING IT PURPLE ALL PIPING SHALL BE INSTALLED IN COMPLIANCE WITH 248 CMR, OR A METHOD APPROVED BY THE BOARD ALL PIPING SHALL BE LABELED EVERY 10 FEET AT ALL BRANCHES AND BOTH SIDES OF ALL PENETRATION GRAY WATER SYSTEMS. PG 47

Slide 52: 

GRAY WATER CON. ALL TERMINATION POINTS, OTHER THAN FIXTURES SHALL BE IDENTIFIED AS GRAY WATER SYSTEMS. THE OWNER OF THE EQUIPMENT SHALL COMPLY WITH THE OPERATIONS AND MAINTENANCE MANUAL, WHICH SHALL BE SUPPLIED BY THE MANUFACTURER. ALL WATER WHICH IS TO BE USED FOR FIXTURES SUPPLIED BY THE GRAY WATER SYSTEM SHALL BE IDENTIFIED BY ADDING A NON TOXIC BLUE DYE. ALL GRAY WATER SYSTEMS SHALL BE TREATED PRIOR TO RE-USE. PG 48

Slide 53: 

HOT WATER RETURN CIRCULATION SYSTEM HOT WATER SUPPLY SYSTEMS IN BUILDINGS WHERE THE DEVELOPED LENGTH OF HOT WATER PIPING FROM THE SOURCE OF HOT WATER SUPPLY TO THE FURTHEST FIXTURE SUPPLY EXCEEDS 100 FEET SHALL BE OF THE TOTAL RETURN CIRCULATION TYPE OR SHALL BE MAINTAINED AT THE DESIGN TEMPERATURE USING A SELF REGULATING HEATING CABLE. 10.14 H PG 49

Slide 54: 

HOT WATER RETURN CIRCULATION SYSTEM CON. 10.14 H A COMPONENT OF A PLUMBING SYSTEM THAT MOVES HOT WATER TO FIXTURES QUICKLY WITHOUT WAITING FOR THE WATER TO GET HOT. DURING LOW, OR NO FLOW CONDITIONS, A HOT WATER CIRCULATION PUMP SENDS THE COOL WATER THAT HAS BEEN SITTING IN THE HOT WATER DISTRIBUTION SYSTEM PIPING BACK TO THE HEATER. WHY IS THIS IMPORTANT? CONSERVATION OF WATER – ACCORDING TO U.S. DEPART- MENT OF ENERGY AND CENSUS BUREAU, BETWEEN 400 BILLION AND 1.3 TRILLION GALLONS OF WATER ARE WASTED NATIONALLY BY HOUSE HOLDS PER YEAR WAITING FOR HOT WATER. PG 50

Slide 55: 

HOT WATER RE – CIRCULATION CONTINUED 2) MUNICIPAL ENERGY WASTE – THE DOE ESTIMATES THAT 800 TO 1600 KILOWATT HOURS PER YEAR ARE USED TO TREAT AND PUMP THE WATER TO HOUSEHOLDS THAT WILL EVENTUALLY BE WASTED WHILE THE OCCUPANT WAITS FOR TAP WATER TO WARM TO THE DESIRED TEMPERATURE. WHEN DO WE NEED THIS SYSTEM? 248 C M R 10.14 ( 4 ) ( H ) HOT WATER SUPPLY SYSTEMS IN BUILDINGS WHERE THE DEVELOPED LENGTH OF HOT WATER PIPING FROM THE SOURCE OF HOT WATER SUPPLY TO THE FIXTURE SUPPLY EXCEEDS 100 FT.

OVERHEAD GARAGE DOOR POLICY ENACTED 4/7/10, AMENDED 5/5/10 248 CMR 10.09(1)(A) REQUIRES INTERCEPTORS AND SEPARATORS “TO PREVENT THE DISCHARGE OF OIL, GASOLINE, GREASE, SAND, AND OTHER SUBSTANCES, THAT ARE HARMFUL OR HAZARDOUS TO THE BUILDING DRAINAGE SYSTEM, THE PUBLIC SEWER, OR SEWAGE TREATMENT PLANT OR OTHER SEWAGE TREATMENT PROCESSES.” IT IS THE INTERPRETATION OF THE BOARD THAT SUCH PREVENTION IS REQUIRED FOR ANY BUILDING SUBJECT TO THE STATE PLUMBING CODE WHICH UTILIZES GARAGE OR OVERHEAD DOORS SUFFICIENTLY WIDE TO ALLOW THE ENTRANCE OF A TRUCK OR AUTOMOBILE. THIS INTERPRETATION DOES NOT APPLY TO SINGLE FAMILY RESIDENTIAL GARAGES OR EXTERIOR STORAGE SHEDS THAT DO NOT CONTAIN ANY PLUMBING AND ARE NOT PART OF ANY OTHER STRUCTURE. PG 52
