4.         Control of toxic substances, hazardous materials and radiation

 

5.         The presence of chemical, physical, and biological elements and agents that adversely affect and alter ecological balances

 

6.         Degradation of the esthetic use of the environment

 

7.         Impact on daily activities such as traffic.

1.3       PROTECTION OF NATURAL RESOURCES

 

  A.      General:  Requirements of this article are in addition to the Special Condition "Protection of Property."  It is intended that the natural resources within the boundaries and outside the limits of the work site shall be preserved in their existing condition or be restored to an equivalent of the existing condition, as approved by the Owner, upon completion of the work.  The Contractor shall confine his on-site construction activities to areas defined by the contract.

 

  B.      Protection of Existing Waterways and Highways:  Waste of any kind shall not be dumped into or be allowed to fall into the sea, onto adjacent banks, or onto highways. This shall include paint splatters and spillage during painting operations.  Care shall be taken to prevent damage and injury to personnel, vessels, and vehicles using waterways, highways, or pedestrian ways.  Devices shall be provided and maintained by the Contractor as required to prevent such occurrences.  Any material or items falling into the sea, onto adjacent banks, or onto highways shall be promptly removed.

1.         Except in areas indicated to be cleared, the Contractor shall not remove, cut, deface, injure, or destroy vegetation without special permission from the Owner.

 

2.         The Contractor shall submit a plan for protecting existing vegetation that is to remain and that may be injured, bruised, defaced, and otherwise damaged by construction operations.

 

3.         Rocks that are displaced into un cleared areas shall be removed.  Monuments, markers, and works of art shall be protected prior to the start of operations.

 

4.         A preconstruction survey including photographs shall be accomplished by the Contractor and a copy of survey furnished to the Owner.

  E.      Fish and Wildlife Resources:  The Contractor shall not alter water flows and otherwise disturb native habitat adjacent to the work site.

 

  F.       Protection of Existing Wetlands and Watercourses:

 

1.         Work shall be planned, scheduled, and undertaken in a manner that will ensure the protection and preservation of existing wetlands and watercourses.

 

2.         Work in and around wetlands and watercourses shall be undertaken in a manner that will prevent significant impact upon public health, safety, and welfare.

 

1.4       EROSION AND SEDIMENT CONTROL MEASURES

 

  A.      Burn-off of ground cover will not be permitted.

 

  B.      Borrow areas shall be managed and controlled to prevent sediment from entering nearby water.  Restoration of the area, including areas outside the borrow area disturbed by the borrow and haul operations shall include grading, replacement of topsoil, and establishment of permanent vegetation cover.  The vertical sides of the borrow pit shall be uniformly graded to a slope of not more than 30 degrees.  The bottom of borrow pits shall be uniformly graded to provide a flat bottom and shall be drained by outfall ditches or other suitable measures approved by the Owner.

 

  C.      Reduction of Exposure of Unprotected Erodible Soils:  Side slopes and backslopes shall be protected immediately upon completion of rough grading.  Operations in connection with earthwork shall be planned and conducted in such a manner as to minimize the duration of exposure of unprotected soils.

 

  D.      Temporary Protection of Erodible Soils:

 

1.         Such methods as necessary shall be used to effectively prevent erosion and control sedimentation.

 

2.         Temporary protection shall be provided on all side slopes and back slopes as soon as rough grading is completed or sufficient soil is exposed to require protection to prevent erosion.

 

1.5       CONTROL AND DISPOSAL OF CHEMICAL WASTE

 

  A.      Chemical waste shall be stored in NFPA approved corrosion resistant containers with lids, removed from the project site, and disposed of as necessary, but not less frequently than monthly.  Disposal of chemical waste shall be in accordance with standard established practices as approved by the Owner.

 

  B.      Fueling and lubricating of equipment and motor vehicles on-site shall be conducted in a manner that affords the maximum protection against spills and evaporation.
