3. DISPOSAL OF WASTE MATERIAL:

General: Wastes generated on SNR projects will be managed in accordance with this section, and in accordance with applicable Federal, State and local regulations. In addition to the requirements of the Contract Clause “Cleaning Up”, remove all waste material from the construction site. No waste shall be left on WAPA property, right-of-way or easement.

Burning or burying of waste material is not permitted.

Hazardous, Universal and Non-Hazardous Wastes: If required, disposals of hazardous waste will be coordinated by the COR and Environment. WAPA will be the generator of hazardous waste. Maxwell Substation does not have a permanent EPA ID number The COR will be responsible to communicate the need for a temporary EPA ID number to WAPA Environmental compliance at least 1-week prior to the date it is needed to facilitate disposal of hazardous wastes.

The Contractor will work closely with the COR, electricians and the project manager to coordinate the timing of disposals of hazardous waste with WAPA Environmental. WAPA Environmental will engage the services of the disposal contractor and will be onsite to sign the manifest for wastes going out on a hazardous waste manifest carrying this ID number.

Used oil is a hazardous waste in the State of California. Prior to recycling, oil from breakers, transformers and other oil-filled electrical equipment must be sampled and analyzed for polychlorinated biphenyls, using analytical methods approved by EPA and applicable state regulations.

Sampling and Testing of Insulating Oil for PCB Content: The KE electricians will sample the oil from equipment slated for disposal on the first day of the outage and turn the sample(s) over to WAPA Environment as soon as practicable. WAPA Environment will have the samples analyzed for PCBs and make the determination of how the oil will be removed from the equipment and hauled away. Sampling equipment will be decontaminated and disposed according to documented good laboratory practices (these can be contractor developed or EPA standards), and in compliance with hazardous waste regulations.

Removal and Disposal of Insulating Oil and Oil-Filled Electrical Equpment: The Contractor will be responsible to haul empty equipment to the scrap metal recycler.

Recycled Materials: Reduce wastes, including excess WAPA material, by recycling, reusing or reprocessing. Examples of recycling, reusing or reprocessing includes, but is not limited to, reprocessing of solvents; recycling cardboard; and salvaging scrap metals. All materials generated from the project that can be recycled, shall be recycled. The Contractor shall record quantities of material by category that is salvaged, recycled, reused or reprocessed, and report them in the recycled materials quantity report as required in the submittals section. These materials include, but are not limited to:

Steel: Weight in pounds or tons.

Aluminum: Weight in pounds or tons.

Copper: Weight in pounds or tons.

Other Metals: Weight in pounds or tons.

Gravel, Asphalt, or Concrete: Weight in pounds or tons.

Batteries: Weight in pounds.

Wood Construction Material: Weight in pounds.

4. MATERIAL WITH LEAD-BASED PAINT:

General: The Contractor will comply with all applicable Federal, State and local regulations concerning any work with items containing lead-based paint, including disposal of material painted with lead-based paint and all other management of these materials. OSHA and General Industry Standards apply to worker safety and right-to-know issues. Federal EPA and State agencies regulate waste disposal and air quality issues.

Testing: If lead is suspected on an item of equipment, the item shall be tested for the presence of lead. A swipe style test can be used to make this determination, and it can be performed by WAPA Environment, electricians or the COR.

Working With Lead Painted Equipment: If lead is determined to be present, the equipment may still be recycled. If the item must be cut into pieces to get it on a truck or for any other reason, any resulting paint waste (from the associated cutting sanding, stripping or abrading) is hazardous waste and must be managed as such. The Contractor and COR will consult with WAPA Environmental, who will engage the services of a disposal contractor and will be onsite to sign the manifest for wastes shipped on a hazardous waste manifest.

Transfer of Property: If lead-based paint-containing equipment or material is to be given away or sold for reuse, scrap or reclaiming, the Contractor shall provide a written notice to the recipient stating that the material contains lead-based paint and that the Hazardous Waste regulations may apply to the waste or the paint in some circumstances. The new owner must also be notified that they may be responsible for compliance with OSHA requirements if the material is to be cut, sanded, abraded or stripped of paint. The Contractor will also submit a copy of any required lead paint notices with Contractor and recipient signatures to the COR prior to submittal of final invoice in accordance with the submittals section.

Certificates of Disposal and Receipts: Obtain receipts from the landfill or scrap metal recycler and submit copies to the COR prior to submittal of final invoice.

5. CONTRACTOR'S LIABILITY FOR REGULATED MATERIAL INCIDENTS:

General: The Contractor is solely liable for all expenses related to spills, mishandling or incidents of regulated material attributable to his actions or the actions of his subcontractors.

This includes all response, investigation, cleanup, disposal, permitting, reporting and requirements from applicable environmental regulation agencies.

Supervision: The actions of the Contractor employees and subcontractors shall be properly managed at all times on WAPA property or while transporting WAPA’s (or previously owned by WAPA) regulated material and equipment.

6. POLLUTANT SPILL PREVENTION, NOTIFICATION AND CLEANUP:

General: Provide measures to prevent spills of pollutants and respond appropriately if a spill occurs. A pollutant includes any hazardous or non-hazardous substance that when spilled, will contaminate soil, surface water or ground water. This includes any solvent, fuel, oil, paint, pesticide, engine coolants and similar substances.

Spill Prevention Notification and Cleanup Plan (Plan): Provide the Plan to the COR for review and comment 14-days prior to start of work. Review of the Plan is for the purpose of determining compliance with the specifications only and shall not relieve the Contractor of the responsibility for compliance with all Federal, State and local regulations. Include the following in the Plan:

Spill Prevention Measures: Describe the work practices or precautions that will be used at the jobsite to prevent spills. These may include engineered or manufactured techniques such as installation of berms around fuel and oil tanks; storage of fuels, paints and other substances in spill proof containers; and management techniques such as requiring workers to handle material in certain ways.

Notification: Most States and the Environmental Protection Agency require by regulation that anyone who spills certain types of pollutants in certain quantities notify them of the spill within a specific time period. Some of these agencies require written follow up reports and cleanup reports. Include in the Plan the types of spills for which notification would be made, the agencies notified, the information the agency requires during the notification and the telephone numbers for notification.

(a) If a spill happens that is over 10-gallons or any amount reaches a waterway:

1) Contact the COR immediately.

2) Call SNR Dispatch Emergency at (916) 353-2201.

Employee Awareness Training: Describe employee awareness training procedures that will be implemented to ensure personnel are knowledgeable about the contents of the Plan and the need for notification.

Commitment of Manpower: Equipment and Material. Identify the arrangements made to respond to spills, including the commitment of manpower, equipment and material.

If applicable, address all requirements of 40CFR112 pertaining to Spill Prevention, Control and Countermeasures Plans.

7. PREVENTION OF AIR POLLUTION:

General: Ensure that construction activities and the operation of equipment are undertaken to reduce the emission of air pollutants .
