Construction Mitigation Measures & Best Practices:
All activities will begin with the implementation and installation of Best Management
Practices (BMP)). These practices include:
Proposed Hauling/ Transportation routes Contractors will submit hauling plan
as required and will follow a city approved route. No evening hauling on city roads
expected
Construction.
The actual Construction will be accomplished by a Construction contractor.
The contractor will call for all required inspections, as well as site pre-construction
meeting. The contractor will keep records of any special inspections at the construction
site
Storm Water Construction will start with the implementation and installation of
Best Management Practices (BMP) for Temporary Erosion and Sedimentation Control
(TESC) under supervision of Boeing Environmental personnel. All storm water drain
inlets in and around the proposed construction operations and staging areas will be
surrounded by oil absorbent padding to mitigate the potential of any hydraulic/fuel
leakages emanating from construction machinery entering the watershed
Snow, Ice, dirt and mud removal Contractor shall remove snow and ice to the
extent necessary to perform the work. The use of calcium chloride or other chemicals will
not be permitted to remove snow or ice. Contractor shall assure that vehicles are
constructed, loaded, maintained and covered as necessary to prevent the deposition of
dirt, mud or other debris on public roadways. Dirt mud or debris shall be removed on
continual basis. Any dirt, mud or debris dropped by vehicles shall be removed
immediately.
Dust Control Through the entire construction period the Contractor shall take all
necessary steps to dust control all working area and unpaved roads. The use of calcium
chloride or other chemicals will not be permitted for dust control. The Contractor will
accomplish dust control by watering and sprinkling to satisfactorily settle the dust.
Contractor shall comply with any requirements imposed by law to prevent fugitive dust
emissions. All demolished materials and debris will be stockpiled on site to prevent dust
and sedimentation from migrating onto roadways. Contractor vehicles that are
transporting materials to and from the site will be required to have tires washed prior to
leaving the site. This will prevent dust and sedimentation from entering nearby
roadways.
