3. WESTERN AREA POWER ADMINISTRATION, SIERRA NEVADA IDLING POLICY:

Idling of diesel equipment is limited by the idling policy below. This policy is in place to comply with the State Implementation Plan, and to comply with Standard Operating Procedures agreed to in WAPA’s Environmental Assessments and Environmental Impact Statements.

a. The Contractor Fleet must meet the following idling limits:

(1) Idling Limit - No vehicle or engines in the Contractor fleet may idle for more than Five

(5) consecutive minutes. If the Contractor rents or leases an item of diesel equipment, compliance with this idling policy shall be the responsibility of the Contractor and that will be indicated in the lease agreement.

(2) This idling limit does not apply to:

(a) Idling when queuing,

(b) Idling to verify that the vehicle is in safe operating condition,

(c) Idling for testing, servicing, repairing or diagnostic purposes,

(d) Idling necessary to accomplish work for which the vehicle was designed (such as operating a crane),

(e) Idling required to bring the machine system to operating temperature,

(f) Idling necessary to ensure safe operation of the vehicle,

(g) Idling of utility vehicles necessary in order to operate flashing lights for jobs that occur on roadways and other hazard areas, and

(h) Idling of utility vehicles when necessary to avoid a safety emergency.

Operators working with high-voltage equipment must remain in constant contact with other operators of the electric grid via radio in order to avoid safety incidents. For jobs performed at night spotlights may be required. In order to ensure the safety of these operators, the engine may need to remain running beyond the regulation’s five-minute limit.

b. Dust Abatement: Dust shall be controlled. Oil shall not be used as a dust suppressant. Dust suppressants shall be approved by the COR prior to use.

c. Project Specific: The Contractor will implement the correct standard operating procedures for the project location. standard operating procedures (SOPs) are described below by area.

For work occurring in the South area ROW, the following SOPs for air quality apply:

(1) AQ-SOP-1: WAPA will adhere to all applicable requirements of those agencies having jurisdiction over air quality matters, and any necessary permits for O& M will be obtained.

(2) AQ-SOP-2: Machinery and vehicles will be kept in good operating condition and older equipment will be replaced with equipment meeting applicable emission standards;

appropriate emissions-control equipment will be maintained for vehicles and equipment, per EPA and/or WAPA air-emission requirements.

(3) AQ-SOP-3: Idle equipment will be shut down when not in active use; visible emissions from stationary generators will be controlled.

(4) AQ-SOP-4: Dust-control measures will be implemented in road construction and maintenance, as needed. Trucks transporting loose material will be covered or maintain at least two feet of freeboard and will not create any visible dust emissions.

(5) AQ-SOP-5: There will be no open burning of construction trash.

(6) AQ-SOP-6: Grading activities will cease during periods of high winds (as determined by local air quality management districts.

(7) AQ-SOP-7: Major operations will be avoided on days when the local Air Quality Index is expected to exceed 150. Lawrence Livermore Substation is located in the Bay Area Air Quality Management District and the air quality index for the area may be reviewed here: http://www.baaqmd.gov/about-air-quality/current-air-quality.

4. MATERIALS WITH LEAD-BASED PAINT AND/OR ASBESTOS:

a. General: The Contractor will comply with all applicable Federal, State, and local regulations concerning work with and management of wastes with lead-based paint and asbestos.

OSHA and General Industry Standards apply to worker safety and right-to-know issues.

Federal EPA and State agencies regulate disposal and air quality issues.

b. Project Management: If lead or asbestos is suspected at the project location and must be removed or disposed, associated sampling and waste disposal will be coordinated with WAPA Environment.

c. Transfer Of Property: If an item of equipment or material with lead paint is to be given away or sold for reuse, scrap, or reclaiming, the Contractor shall provide a disclosure statement to the recipient of the material stating that the material contains lead-based paint. 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 submit a copy of lead paint disclosures with contractor and recipient signatures to the COR prior to submittal of final invoice.

5. WASTE DISPOSAL:

Used oil is a hazardous waste in the state of California, and disposal of oil and oil filled equipment will be coordinated between the Contractor, the COR, and WAPA Environment.

The Contractor will collect oil samples and nameplate photographs and submit them to WAPA Environment. Environment will manage oil disposal. The Contractor will be responsible to haul empty equipment for metals recycling. Oil filled equipment that cannot be drained on-site will be stored at the location of the Foreman III Electrician’s choice and its disposition will be managed by Environmental at the close of the project.

Livermore substation does not have a permanent hazardous waste registration number, and WAPA Environment will need to obtain a temporary ID# for use on the manifest(s) before waste can be shipped from this location. The temporary ID number will only be usable (i.e.

WAPA will be able to ship hazardous wastes using it) for 90 days. Requesting multiple temporary ID numbers subjects WAPA and the project to regulatory scrutiny. For this reason, the Contractor will be responsible to coordinate carefully with the COR and WAPA Environment to ensure that this number is generated prior to the date waste is hauled, and that hazardous waste on the project is generated within the same 90-day window.

6. POLLUTANT SPILL PREVENTION, NOTIFICATION, AND CLEANUP:

a. 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.

b. Spill Prevention Notification And Cleanup Plan (Plan): Per the submittals section, the

Contractor will provide the Plan to the COR for review and comment 14-days prior to start of work. Review of this plan is for the purpose of determining compliance with the specifications only and shall not relieve the Contractor of their responsibility for compliance with all Federal, State and Local regulations. Include the following sections in the plan: Spill Prevention Measures, Notification Planning, Employee Awareness Training, Commitment http://www.baaqmd.gov/about-air-quality/current-air-quality of Manpower and Material. Also address requirements of 40 C.F.R. § 112 pertaining to Spill Prevention, Control and Countermeasures if applicable. A template plan is available from WAPA environment upon request. In general, the topics below must all be addressed in the plan.

(1) Spill Prevention Measures: Describe the work practices or precautions that will be used at the job site 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.

(2) 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.
