PROJECT DESCRIPTION Scanship Environmental

AS and consists of a multichamber incinerator that uses a semi-pyrolitic two stage cumbustion

Main components of the incinerator system consists of a garbage shredder, silo feeding conveyor screw, garbage silo, incinerator, flue gas fan and emission stack

EXISTING ENVIRONMENT- PHYSICAL

EXISTING ENVIRONMENT- BIOLOGICAL

Highly altered ecology – site & situation of airport environment

Site adjacent to highly degraded, isolated wetland – remnant of old coastal vegetation

Robust bird life in wetlands and ponds Airport site adjacent to Montego Bay

Marine Park

EXISTING ENVIRONMENT- SOCIAL

Airport environment – visitor population and airport staff.

Communities on northern fringe – Whitehouse, Sandals ,

Southern extent – Flankers, mixed commercial establishments, north coast main road

TERMS OF REFERENCE – KEY ISSUES

Site preparation and Construction phase site clearance (burnt garbage) material sourcing and storage, dust control, construction site management, synergy with on-going expansion work

…Key Issues - Operation Phase

Waste collection, sorting,transport, loading Ash handling and disposal HazMat Air dispersion modeling – ambient air quality

and public health in the airshed Occupational Health and Safety issues Focus on Sox, Nox, particulates(TSP,PM10),

PAPS – dioxins and furans Environmental Monitoring Plan Emergency Response Plan

APPROACH TO STUDY Multidisciplinary team Charette style investigation and

analysis Review of existing documentation Field investigations & analysis Air dispersion modeling Public presentation

LEGISLATIVE AND REGULATORY CONSIDERATIONS

Local and International NEPA – Draft air Regs Public Health Airport Operations Waste handling NSWMA – Ash handling and Landfill

guidelines

AIR QUALITY SCREENING MODEL

NEPA requirements – Screening Initial assessment of emission levels and

range of dispersion Compliance with local a/q standards If compliant – no further modeling If non-compliant – recommendations for

a/q control device(s) If major disparity – then detailed

dispersion modeling

SCREENING MODEL ScreenView Software Basic Inputs

Emission stack configuration,i.e. height, internal diameter for respective incinerator

Emission characteristics,i.e. flue gas flow rate, temperature

Emission rates of pollutants (USEPA emission factors)

IMPACTS & MITIGATION   

AIR QUALITYISSUES MITIGATION

MEASURESCONSTRUCTION PHASE Dust Emissions from transport & storage of construction materials

 

 Covering trucks & material stockpilesUse of dust masks by workers

OPERATION PHASE Stack emissions - SOX, NOX PAPs and particulates Model indicates these parameters within acceptable limits.

Air pollution control devices - Furans and dioxins comply with the national standards.Scheduled Maintenance & operation

 

  

IMPACTS AND MITIGATION  WASTE MANAGEMENT

Construction Debris Worker generated waste

Separation & storage Removal by certified

contractors HazMat handling Training re worker

disposal of packaging etc. Chemical toilets & proper

disposal

...WASTE MANAGEMENT Operation Collection, transport,

sorting, loading of waste to incinerator

Ash generation, removal and disposal

Scavenging

Procedures established NSWMA guidelines –

Containerize ash Separate special /medical

waste-get NSWMA and Min Health approval for this component

Security to guard against scavenging

ALTERNATIVES No Action

Not an option Alternative Incinerator

AAJ selection after due diligence – purpose built to meet specs Alternative Sites Disposal Method -

Health guidelines incineration of international waste. Landfill exposure Burial on site – impractical

MONITORING PLAN Ensure compliance with relevant legislation,

implementation of the mitigation measures and long-term minimization of negative environmental impacts.

Programme of stack emission testing including medium term monitoring provisions.

Comprehensive Waste Management Plan- various aspects of the incinerator operations.

 Include Emergency Response Plan- specific procedures for dealing with natural and man-made emergencies.
