Equipment warranties (modules, inverters, etc.) are shorter than the expected service life. With a 30-year system life, it is common and well understood by industry that inverters and a small percentage of failed modules would need to be replaced, though the system as a whole would provide at least 30 years of service. The Government shall seek the type of equipment and workmanship that can result in a 30-year system.

Locating Site Utilities The Contractor is responsible for locating all existing underground utilities prior to excavation and for utilizing the “Call Before You Dig” hotline to confirm with any potentially affected public utility company.

A notification of 72 hours in advance shall be given to the Government to locate the utilities belonging to the Government. If the Contractor fails to have these services performed, it will be the Contractor's responsibility to make temporary repairs to damaged underground utilities immediately, and permanent repair within 24 hours, at no expense to the Government. Any repairs made to the underground utilities by the Contractor shall be inspected by a Government representative before backfilling. Any damage done to existing underground utility systems are the sole responsibility of the Contractor.

Any site utility drawings provided by the Government, utility companies, municipal and county agencies, and prior Government contractors are for informational purposes only and are to be considered incomplete and inaccurate. The Contractor is responsible for confirming the exact location, depth, and type of underground utilities present.

Underground utilities that may be found traversing the proposed array areas might include but are not limited to: telecommunications trunks; cable TV lines; electrical distribution conductors; water mains;

oil, steam, propane, and natural gas lines; access and security camera systems; waste water and/or storm water drain pipes; traffic and/or street light power; and communications cabling.

DISPOSAL OF RUBBISH AND DEBRIS: Materials defined in paragraph a. (3) and a. (4) above shall be disposed of OFF FWS PROPERTY.

(a) In the event the contractor or subcontractor should dump rubbish/debris at any area of FWS, the contractor shall be required to retrieve this rubbish/debris and dispose of OFF FWS PROPERTY to a certified landfill.

(b) The contractor shall provide proof of an approved, certified landfill prior to the removal of lead containment materials and asbestos material. All dump tickets from the approved landfill shall be provided to the COR.

(2) GARBAGE: The contractor shall dispose of all garbage OFF FWS PROPERTY. Garbage shall be kept in sealed metal containers and disposed of daily. The preparation, cooking, or disposal of food on the project site is strictly prohibited.

(3) SEWAGE, ODOR, AND PEST CONTROL: Chemical toilets or comparably effective units shall be utilized in accordance with Federal, State, and Local regulations. Wastes shall be periodically collected and removed from the site by a licensed sewage disposal contractor.

Measures shall be taken to control pests and to mask or eliminate undesirable odors. Chemical toilets shall be cleaned/serviced by a licensed company at least every 2 weeks.

(4) DISPOSAL OF HAZARDOUS WASTE: Materials defined in paragraph 2-20 a. (7) shall be disposed of utilizing the following guidelines:

a. Hazardous waste must be disposed of at an EPA approved Treatment, Storage, and Disposal Facility (TSDF) in accordance with applicable Federal, State, and Local regulations.

b. Prior to transporting waste off-site, the contractor must:

[2] If applicable, provide a copy of the TCLP results from analysis performed to identify the waste as hazardous (e.g., lead concentrations above 0.5 mg/l).

[3] Notify the FWS Environmental Compliance Officer twenty-four hours before hazardous waste is to be removed from the site to ensure someone will be available to check the shipment and sign the appropriate paperwork.

c. To transport the waste off-site, the contractor must: Provide a completed Hazardous Waste Manifest and its supporting documentation to the Environmental Manager’s Inspector during the loading of the transportation vehicle. If the shipment is approved, the Environmental Manager’s Inspector will sign the Manifest and supporting documents. All waste will be transported in accordance with Federal, State, and Local Department of Transportation regulations.

Provide appropriate copies of the Hazardous Waste Manifest and supporting documents to the Environmental Manager’s Inspector.

Note: If the shipment is not approved, the Manifest will not be signed, and the material may not be removed from the site. All cost incurred due to an unapproved shipment will be the responsibility of the contractor.

e. LEAD CONTAMINATED MATERIALS: Debris containing lead contamination at 0.5 mg/l or higher, determined by either analysis prior to or after demolition/renovation, must be handled as Hazardous Waste in accordance with paragraph 2-20 d (4) above. Transportation of this material off-site must be accomplished by an approved DOT method. In most cases, lead contaminated debris will be placed in a sift-proof, roll-off container or trailer, covered by a secured tarp. As stated above, if shipment is not approved due to improper methodology or inadequate transportation vehicle, the Manifest will not be signed, and the material may not be removed.

Costs incurred for the delay in shipment will be the responsibility of the contractor.

g. CLEAN AIR/CLEAN WATER: The contractor shall not utilize equipment that has emissions which exceed limitations under the Clean Air Act and the facility’s Title 5 Permit. Steps shall be taken to prevent the discharge of pollutants into or on any land or water.

TRUCK HAULING ON FWS property: The contractor shall be responsible for covering open-bodied vehicles that are transporting sand, gravel, fill materials, dirt, construction debris and any other material which may become airborne and/or possibly create air pollution while on FWS property.
