DFD Project No. 26 05 02 - 2 1 Provide supplemental support for conduits that are routed through demolition area, and are to remain. Supplemental 2 support shall be added so that the conduit meets the support requirements of electrical specification section 26 05 33. 3 4 PCB BALLAST HANDLING 5 Generally, all high power factor fluorescent light ballasts manufactured before 1978 and some HID ballasts contain 6 polychlorinated biphenyl (PCB) compounds in their capacitors. The Contractor shall inspect all ballasts in all light 7 fixtures and take the actions described below. 8 9 The disposal of all ballasts labeled as "NON-PCBs" or "NO PCBs" shall become the responsibility of the 10 Contractor. If the PCB content is not stated on the ballast label, the ballast shall be handled as a PCB 11 ballast. 12 13 All PCB ballasts shall be removed from the light fixtures and shall have the wires clipped off. However, 14 before removal, all PCB ballasts shall be carefully inspected for leaks. If a ballast appears to be leaking 15 (evidenced by potting compound leaking out or by an oily film on the ballast surface) the ballast must be 16 handled per EPA and DNR PCB regulations. Basically, this means the ballast is to be carefully removed 17 from the fixture and placed in an approved drum. See paragraph below for the drum specifications. The 18 person removing the ballast from the fixture shall wear protective gloves, eye protection, and protective 19 clothing as necessary. 20 21 If the fixture has also been contaminated, it must be cleaned to less than 10 micrograms/100 square 22 centimeters contamination before disposal. This cleaning must be done by an approved PCB contractor 23 and is not considered a part of this contract. Contact DFD for contractor approval before commencing with 24 the cleanup. 25 26 The PCB ballasts shall then be placed in US DOT approved drums (barrels). The contractor may furnish 27 their own drums or obtain them from Lamp Recyclers Incorporated (800-558-1166). The quantity and size 28 of the drums will be determined by the contractor at the time of construction, 30 and 55 gallon drums are 29 typically available. 30 31 These PCB drums shall be placed in storage with the cover that came with the barrels, in a location within a 32 building, as designated by the Building Manager or DFD Field Representative. The drums are not to be 33 placed outside where they are exposed to weather. 34 35 THESE PCB BALLASTS ARE NOT TO BE REMOVED FROM THE WORK SITE BY THE 36 CONTRACTOR. To do so would be a violation of DNR and DOT hazardous waste regulations and may 37 result in a fine to the Contractor. 38 39 The Contractor shall label and mark the PCB storage drums with EPA approved PCB labels and the storage 40 area with signs, marks and lines to meet the regulations of Wisconsin Code NR 157 – Management of 41 PCBs and Products Containing PCBs. 42 43 The Contractor shall also provide approved PCB absorbent materials to be stored immediately adjacent to 44 the drum storage area. Do not place loose absorbent material in the drums. 45 46 The Contractor shall provide to the DFD Field Representative, in written form, a total count of these 47 ballasts (or their total weight by drum) and where they are stored. 48 49 See Lamp and PCB Ballast Disposal instructions below. 50 51 LAMP AND PCB BALLAST DISPOSAL 52 All lamps (fluorescent, incandescent, and HID) contain mercury and/or lead (in the base) as well as other heavy 53 metals and compounds which are regulated by the EPA and DNR during the disposal process. As a result, 54 regulations have been issued covering the handling and disposal of all lamps. Lamps which have been removed 55 from service for disposal shall be handled as follows by the Contractor: 56 57 The Contractor shall very carefully remove all lamps (fluorescent, incandescent, and HID) from light 58 fixtures before removal of the fixture from its mounted position. This is to reduce the likelihood that the 59 lamp(s) will be broken. The Contractor will be charged the cost difference between disposal of broken and 60 unbroken lamps, for all lamps broken in excess of 1% of the total lamps removed in the project. 61 62 The contractor shall contact Lamp Recyclers Incorporated (800-558-1166) to coordinate the storage and 63 pickup of disposed lamps and PCB ballasts. The contractor may furnish their own containers or obtain 64 them from Lamp Recyclers Incorporated. Removed lamps and PCB ballasts shall be placed in containers

DFD Project No. 26 05 02 - 3 1 by the contractor, marked with the number and type of lamp and PCB ballast, and placed in storage at a 2 location on the user agency’s property. The contractor shall label the area as “Hazardous Material 3 Storage”. The contractor shall make arrangements for pickup of the lamps and PCB ballasts with Lamp 4 Recyclers Incorporated, shall provide a count of all stored lamps and PCB ballasts, and shall fill out any 5 required forms. 6 7 When making disposal arrangements with Lamp Recyclers Incorporated, the contractor shall make sure to 8 notify them of the DFD project number, DFD project name and DFD Project Manager, for invoicing 9 purposes. Invoicing from Lamp Recyclers Incorporated shall be sent to the DFD Project Manager for 10 direct charge payment from the project (lamp and PCB ballast disposal costs to be paid by DFD), and shall 11 indicate the proper DFD project number, name, and PM. 12 13 The contractor shall coordinate the lamp and PCB ballast disposal with the DFD Field Representative. 14 15 END OF SECTION 16
