PROTECTION OF ENVIRONMENT

PART 1 - GENERAL

1.01 SUMMARY:

A. Contractor, in executing Work, shall maintain Work areas on- and off-site free from environmental pollution that would be in violation of federal, state or local regulations as indicated and in compliance with Contract Documents.

C. Any contamination shall be reported by the Contractor to the appropriate agencies, Owner and the Engineer, and cleaned up as per requirements.

D. The Contractor shall be responsible for the protection of the natural environment of the Site and surrounding areas, both land and water. Protection of the environment must start with avoidance and prevention, and then control/mitigation, compensation, or enhancement (in order of descending preference).

E. Schedule and conduct all work in a manner that will minimize the erosion of soils in the area of the Work. Provide erosion control measures such as diversion channels, sedimentation or filtration systems, berms, staked hay bales, seeding, mulching, or other special surface treatments as are required to prevent silting and muddying of streams, rivers, impoundments, lakes, etc. All erosion control measures shall be in place in an area prior to any construction activity in that area.

F. Ensure that construction is achieved with a minimum of disturbance to the existing ecological balance between a water resource and its surroundings. It is the Contractor's responsibility to determine the specific construction techniques to meet these guidelines.

G. Schedule and conduct all work in a manner that will minimize the level of noise escaping the site, especially at night and on weekends.

H. Payment:

1. Consider Work specified in this Section incidental and include payment as part of appropriate lump sum or unit prices specified in Bid Form.
