and urban upgrading. This
executive summary to the environmental assessment (EA)
framework provides the regulatory, and policy framework,
and, a methodology framework with which the detailed EA will
be conducted for specific physical investments. It further
provides a generic assessment of potential impacts, based on
the types of the components to be included. Mitigation
measures are stipulated as follows. Dependent on the
characteristics of the receiving water, a variety of one
dimensional and/or two dimensional model tools will be
required to analyze the impact of the discharges on surface
water bodies in the Shanghai area. The water quality model
will be primarily used for assessment of project impacts,
and should be calibrated with respect to existing
conditions. The models will be applied for both high and ebb
tides, during the dry season, and during the emergency
conditions when the wastewater treatment must be closed, and
wastewaters will be bypassed without treatment. Sludge
disposal is probably the single largest adverse
environmental impact a large wastewater treatment project
can generate. Impact assessment for wastewater treatment
plants must include detailed assessment for sludge handling
and disposal, including sludge generation, thickening and
dewatering, storage, hauling, and disposal. Air emissions
sources from various project facilities in both construction
and operation stages will be identified, and assessed
through dispersion models to determine potential adverse
impacts in project areas, particularly schools and
residential areas. Newly built residential areas within
wastewater treatment catchments, should discharge their
wastewaters through a separate system installed within the
residential area itself; wastewater generated from
restaurants, recreation spots or services locations, should
undergo oil and residue removal pretreatment before
discharged into a wastewater collection network and,
disinfection should be applied to wastewater discharged from
hospitals. Construction noise disturbances shall adopt the
Limiting Values in Construction Area standards. Dam safety
assessment should be identified, implementing the standard
dam safety measures, and necessary remedial works. The use
of biological or environmental control methods should be
promoted, and, reliance on synthetic chemical pesticides
reduced. In general, pest control is implemented through
Integrated Pest Management (IPM) approaches. Regarding
public health projects, controlling pests primarily through
environmental methods is strongly supported. As needed, the
capacity of the country's regulatory and institutional
framework should be strengthened to promote and support
safe, effective and environmentally sound pest management. Show Less -
