Sub-task 1.1 Evaluate Existing and Project Future Hazardous Waste Generation and Treatment, Storage and Disposal Capacity

Step 1.1.1  Collect and Review Hazardous Waste Generation and Accumulation Data.  Review how hazardous waste is defined (e.g., through lists or criteria or both), identified, analyzed, packaged, labeled, accumulated, stored, collected, and transported.  Also, review what recordkeeping and reporting is required by the local regulatory authority to be carried out by hazardous waste generators, transporters, and HWMFs, and to what extent these requirements are complied with.  Collect available information on existing hazardous waste generation, and generators, in the service area.  Include in the review the backlog of hazardous waste in long-term storage at generator sites, at unlicensed or otherwise non-compliant HWMFs, and at sites with contaminated soil and water where hazardous substances were dumped, spilled, or leaked. 

Evaluate how complete, representative, accurate, and precise the available information is.  Determine whether it includes waste properties data relevant to thermal treatment and disposal technologies (heating value, ash content, water content, and typical elemental analysis), as well as other information on the generators (e.g., on-site waste testing, waste transport services, and disposal facilities used, and future plans for pollution prevention, etc.).

Step 1.1.2  Confirm Hazardous Waste Generation Data.  Compare the POPs generation information collected in Step 1.1.1 above to that collected previously in the project area, to data collected in similar cities and regions, and to theoretically derived waste generation estimates (e.g., based on industry-specific waste generation factors and models that can be found in the engineering literature, making sure to correct for country-specific conditions).  Identify any data inconsistencies or gaps among the data sets compared.  Categorize waste collection by applicable energy-content levels. To address the identified data inconsistencies and gaps, design and conduct field spot testing of the data through visits to a limited but representative number of randomly selected POP generators, transporters, HWMFs, and accumulation sites.  Adjust the available data using the results of the field spot-checking.  Determine if a more complete survey will be required and design that survey.  Consider using an Internet project website approach for generators to report their survey data. 

Step 1.1.3 Analyze Trends and Project Future Hazardous Waste Generation.  Evaluate and review current programs for generators or collectors of POP wastes to minimize their POP generation by employing better housekeeping practices and cleaner technology, to separate their hazardous from their non-hazardous wastes, and to exchange their hazardous wastes with other generators who could use the wastes as a raw material in their manufacturing process.  Recommend improvements to these programs and develop scenarios of high, medium, and low pollution prevention impacts on POPs/hazardous waste generation in the project area.  Based on these scenarios and trends in population, economic, and industrial growth over the past ten years, project future hazardous waste generation by energy-content levels for the next ten to twenty years in the service area so that hazardous waste disposal facilities and equipment can be located and sized most cost-effectively.

Step 1.1.4 Evaluate Existing Hazardous Waste Management Facilities.  Collect and review available data on existing hazardous waste transport services and HWMFs and evaluate their locations, capabilities, and capacities by waste type, remaining life, and ownership and operation entities.  Based on this data, determine if additional, more detailed information would be beneficial to the project and, if so, design a questionnaire and carry out such a survey of existing HWMFs.

Sub-task 1.2 Analyze Technical Feasibility of Proposed Hazardous Waste Treatment, Storage and Disposal Units

Step 1.2.1  Prioritize Hazardous Wastes for Treatment, Storage, and Disposal.  Identify and prioritize hazardous wastes to treatment, storage, and disposal facility needs, considering waste characteristics and quantities, human health and environmental risks, and existing HWMF capabilities and capacities. 

Step 1.2.2 Analyze Alternatives for Hazardous Waste Analysis, Collection, and Transport.  Evaluate the need for waste analytical laboratory capability considering the specific waste types and amounts projected; the treatment, storage, and disposal units to be utilized; and the extent of waste analysis capability of the waste generators.  Identify and technically evaluate options for providing hazardous waste collection and disposal services to generators, for the immediate project area and the broader region, and how this may affect the optimal locations, capabilities, and capacities of HWMFs.

Step 1.2.3  Analyze Thermal Treatment Alternatives.  Hazardous waste treatment, storage, and disposal processes evaluated should be based on the waste generation data and market analysis and should include:

• Systems for storage in containers and tanks.

• Liquid waste treatment and recycling, wastewater treatment and recycling, oil and solvent recovery, etc., are associated with thermal treatment systems.

•  Thermal treatment and destruction, including rotary kiln, but possibly also separate liquid waste incinerators or fluid bed incinerators for liquid wastes, sludge wastes, and wastes with high salt content containing POPs; and plasma-arc treatment for selected POPs.

•  Secure landfill, including systems for pre-treatment through stabilization and solidification, run-on and run-off control, leachate control (bottom liners, leachate collection and treatment, leak detection, and groundwater monitoring), and gas collection and cleaning/utilization (if organic wastes will be landfilled)

Step 1.2.4  Develop Design Bases for Selected Alternatives.  Utilizing the thermal treatment alternatives defined in Step 1.2.3 above, and described elsewhere in this text, prepare a preliminary design basis document for each option.  The design basis should include the average and design capacities in terms of waste quantities, general waste characteristics, key treatment parameters, treatment technology, and emissions limitations to be met. 

Step 1.2.5 Prepare Conceptual Designs for Selected Alternatives.  Prepare a conceptual design for each preferred thermal treatment option.  Each conceptual design should include the design basis, process description, block flow diagram, basic material balance, and system footprint.  Also prepare initial cost estimates, including local costs for materials and labor.  Costing categories and formats should allow the estimates to feed directly into the economic and financial analysis of Tasks 2 and 3.

Step 1.2.6 Prepare Specifications and Source Equipment for Selected Alternatives.  Prepare specifications sufficient to include in international tender documents, and provide or arrange contacts for thermal treatment equipment sources.
