that may result in a release of hazardous materials. In addition, emission of hazardous materials
from construction-related activities, pumping proximate to schools, and development near
public airports or private airstrips and wild lands could result in a construction impact.
Development may require construction through or adjacent to contaminated sites, most of which
have already been identified by regulatory agencies, and could lead to a disturbance and release
of hazardous materials. Additionally, construction-related activities such as pumping, pouring,
emptying, injecting, spilling, and dumping or disposing could also release hazardous materials
into the environment. The severity of potential effects varies with the activity conducted, and the
concentration and type of waste present. Construction-related activities will require the use of
construction equipment, construction materials, construction signage, and use, and/or disposal of
hazardous materials, which could involve the use of equipment that contains hazardous
materials (e.g., solvents and fuels, diesel-fueled equipment), or the transportation of excavated
soil and/or groundwater containing contaminants from areas that are identified as being
contaminated, which could increase hazards to the public or environment. During construction,
road closures and detours may be necessary; these are normally part of a Traffic Control Plan or
Transportation Management Plan that allows emergency service providers to be aware of the
current access restrictions and the alternatives available, while allowing people to travel to their
destination.
Impacts HAZ-1 through HAZ-8 provide an extensive listing of regulations, and compliance with
these regulations address normal construction activities from implementing the proposed
MTP/SCS.
Therefore, the potential for adverse construction impacts related to land use changes from
implementation of the proposed MTP/SCS at the regional level are considered less than
significant (LS) for Impact HAZ-9. No mitigation is required.
The proposed MTP/SCS involve the expansion or extension of the transportation system, which
may increase hazards to the public or the environment.
Implementation of transportation improvements could include construction impacts that result
from the routine use, transport, and disposal of hazardous materials and waste by rail or trucks
that share facilities with the public and from reasonably foreseeable upset or accident conditions
that may result in a release of hazardous materials. In addition, emission of hazardous materials
from construction-related activities, pumping proximate to schools, and development near
public airports or private airstrips and wild lands could result in a construction impact.
The construction of transportation projects in the proposed MTP/SCS through or adjacent to
contaminated sites, most of which have already been identified by regulatory agencies, could
lead to a disturbance and release of hazardous materials. Additionally, construction-related
activities such as pumping, pouring, emptying, injecting, spilling, and dumping or disposing
could also release hazardous materials into the environment. The severity of potential effects
varies with the activity conducted, and the concentration and type of waste present.
Construction-related activities will require the use of construction equipment, construction
