Particulate matter is removed from the exhaust gases by a fabric filterseparator called a baghouse. A layer of alkaline dust builds up on the bagand any remaining acid gases are abated as they pass through this layer.
The bags are cleaned periodically and the dust is removed by road tankers toauthorised treatment sites.
Fluidised beds are good for heat recovery processes as they have high heattransfer rates. Boiler water is circulated through the bed via a series of tubes.Steam produced from the boiler is routed to a generator for electricityproduction. Exhaust steam from the turbine is condensed and the heat fromthe condensing steam is discharged to the atmosphere via a twin cell coolingtower.
Aqueous effluent streams are produced by the boiler, cooling tower anddemineralisation plant. This aqueous waste is used as raw water in thechemical waste incineration process on site, or it is treated in the effluenttreatment plant.
3. Summary of plant operation
The plant processed approximately 19,000 tonnes of waste (table 3.1) duringa total of 3,731 operational hours in 2008. The wastes the plant handles fallinto the categories shown in the table. Waste throughput is summarised inFigure 3.1.
Table 3.2 shows the residues produced during 2008. While bottom ash issent to landfill, the fly ash is sent to a site in the north of England for use in aneutralisation process.
Significant outages are listed in table 3.3; these are hours when the plant wasnot operational and were mainly due to necessary repair work. Overall, theplant was operational for 43% of the available operational hours in 2008.
The WTE plant exported 8,744,000 KWh of electricity to the national gridduring 2008. To put this in context, the average household's annual electricityconsumption is approximately 3,300 kWh. This means that the site exportedenough electricity to supply around 2,650 households for the year. Another8,594,000 KWh was exported for use on site.

4. Summary of plant emissions
The site operates under a PPG permit issued by the Environment Agency andall emissions to air, water and land are monitored throughout the year andreported to the Agency. The emission limit values in the permit are setaccording to the emission standards in the Waste Incineration Directive(2000176/EG on the incineration of waste).
Emissions to Air
In order to ensure compliance of emissions to air, the plant has a ContinuousEmissions Monitoring System (GEMS) in place which monitors particulatematter, total organic carbon, hydrogen chloride, carbon monoxide, sulphurdioxide, oxides of nitrogen (NOx) and ammonia while the incinerator isoperational. The total masses of these continuously monitored pollutantsemitted to air in 2008 are shown in table 4.1.

Partlculale matter 470 koTotal Oraanic Carbon 130 ko
Hvdroaen Chloride 1057 kaCarbon monoxide 6,513 koSulohur dioxide 4334 ko
Oxides of nitroaen 33622 kaAmmonia 1,714 ka
Table 4.1: Gonlin
Strict limits are adhered to for half hourly, hourly and daily emissions of thesubstances monitored by GEMS, and the GEMS data is reported monthly tothe Environment Agency. A summary of the GEM data is shown in Table 4.2;further detail can be found in the appendix.
The GEM system reports the concentration of each emission in milligrams percubic metre (mg/m'). The annual half-hour maximum is the highest valuerecorded over any half-hour period during the year. The annual half-hourmean is the average of all the half-hour values recorded during the year. Theannual daily maximum is the highest value recorded over any 24 hour periodduring the year.
ELV stands for Emission Limit Value. Each emission to air (with the exceptionof carbon monoxide) has a half-hour average ELV, for example the limit forparticulate matter is 30 mg/m'. If the concentration of particulate matterexceeds this value over a half hour period then the emission has to bereported to the Environment Agency as an exceedance. There is also a dailyaverage ELV which is lower than the half-hour value. For particulate matterthis is 10 mg/m', and if the concentration of particulate matter measured overa 24 hour period exceeds this value then it must be reported to theEnvironment Agency as an exceedance. The exceedances reported during2008 are listed in section 5.
The continuous emissions monitoring system was operating normallythroughout 2008.
Other emissions to air are monitored periodically by an external contractor.Table 4.3 shows the results of biannual checks for nitrous oxide, ammonia,cadmium and thallium, mercury, other metals (antimony, arsenic, chromium,cobalt, copper, lead, manganese, nickel, tin and vanadium), dioxins/furans,PGS's (polychlorinated biphenyls) and PAH's (polycyclic aromatichydrocarbons). Periodically monitored emissions to air are reported to theEnvironment Agency and must fall within the limits stated in the IPPG permit.
Emissions to Water
The WTE plant does not report any releases to water. Emissions to waterfrom the Fawley site are reported under the HTI plant's permit (Permit No.HP3835UZ).

As described in section 4, the plant operates under a PPC permit which statesthe maximum allowed emission of a given substance over a half hourly, hourlyand daily period. Any emissions which exceed this limit are non-compliant.and must be reported to the Environment Agency with an explanation of theiikely cause and the actions that have been taken to solve the problem. Table5.1 shows the exceedances for 2008.
Hydrochloric acid was detected at a level above the ELV during monitoring byan external contractor. As the onsite monitoring system (CEMS) showed noexceedance at this time, a service was booked for CEMS to ensure itsreliability.
Monitoring during triais for the incineration of woodchip waste detected anelevated release of metals to air. Further investigation indicated that nickelwas the major contributor. As a result of this exceedance the trial was ceasedand the throughput of woodchip was reduced to a previously compliant rate.
A dioxin exceedance was detected by an external contractor during periodicmonitoring of emissions to air. The result has been queried and is to beconfirmed; in the meantime additional controls against dioxin formation arebeing used as a precaution.
Several non-compliant emissions were reported for the release of carbonmonoxide to air. Increased levels of carbon monoxide can be caused byhaving either too much or too littte waste in the fluidised bed, or by poorcombustion of the waste material. Levels below the emission limit value werequickly recovered following these exceedances. The plant was operationai fora total of 3,731 hours during 2008 and met its carbon monoxide limits 99.9%of the time.
It is difficult to gauge the environmental impact of these non-compliances. Inmost cases, very iow limits were exceeded by a small percentage for a shortamount of time and the impact on the environment is likely to be negligible.
The plant was in compliance with the permit conditions for 97.8% of itsoperating hours. For sulphur dioxide, oxides of nitrogen, particulates and totalorganic carbon, the plant complied with its emission iimits 100% of the time.
Table 5.2 shows environmental complaints received by the whole Fawley siteduring 2008. All complaints about the site are fully investigated and anyfindings are reported to the EA and the complainant. Note that the Fawleysite consists of the Waste to Energy Incinerator covered in this performancereport as well as the High Temperature Incinerator, which is covered in aseparate report (see section 7).
The plant received no enforcement actions by the Environment Agency in2008.

to minimise odour aeneration from the use of air lances in the receotion honner.
A variation to the permit was determined in November 2007 allowing theincineration of hazardous waste in addition to MBM. Any new waste type tobe incinerated is subject to rigorous trials and approval by the EnvironmentAgency to ensure that the conditions of the permit are met. The emissionlimit values for the plant remain unaffected. Hazardous and non ha.zardouswoods have both completed their Waste Evaluation Exercises and arepermitted for incineration in the Waste to Energy plant. Several other wastestreams continue to be trialled including sludges from dissolved air flotationprocesses and combustible materials that have been segregated from soilremediation on the London 2012 Olympic Park Site. The plant has completedthe addition of Powdered Activated Carbon to its gas cleaning plant whichshould significantly reduce the potential for dioxin emissions.
Future plans leading to environmental improvement include a new, tighterlimit for emission of carbon monoxide to air which to be introduced byDecember 2009. This will help to improve the air quality in the local area.

Pyros Environmental Lld has been operating the Fawley site since May 2007when the High Temperature Incinerator and the adjacent Waste to EnergyIncinerator were divested from Veolia Environmental Services.
Fawley HTI (High Temperature Incinerator) plant incinerates waste materialscommonly arising from the agrochemical, fine chemical, clinical(pharmaceutical), petrochemical or engineering industries. Significantquantities of redundant chemicals in small quantities arising from the use inschools, universities and research and development establishments are alsoincinerated.

2. Plant description
The site has been processing hazardous waste since 1977. The currentlyoperated High Temperature Incinerator (HTI) was commissioned in 1990.The site undertakes operations and activities in the treatment of hazardouswaste including:
The administration of waste management activitiesThe reception, storage and preparation of wastes prior to incinerationThe incineration processThe exhaust gas cleaning processThe treatment and handling of liquid effluentsThe handling of solid waste residues
The HTI plant is designed to process approximately 45,000 tonnes ofhazardous waste per annum. The plant also disposes of small quantities oflow level radioactive and clinical wastes. Waste is delivered to the site usingroad transport and is received in liquid, solid or sludge form, in bulk tanker,
drums, cardboard kegs, plastic or heavy duty paper sacks, small glass bottlesand in IBC containers. Wastes generally comprise of off-specification rawmaterials or products, process effluents, unwanted by-products and timeexpired products.
The HTI plant is a rotary kiln design that has the capability of handling a widerange of wastes. The incineration process produces two primary wastestreams: slag ash which is a combustion process waste and filter cake whichis the solids waste extracted from the water used to clean the combustiongases.
The process is controlled by a semi-automated system which ensures that theoptimum operating conditions are maintained in order to meet emission limitsset by the Authorisation. Automated control systems maintain the incinerationprocess at the correct temperature and ensure that the waste residence timewithin the kiln is such that the waste is disposed of with due regard toenvironmental impact and compliance with permit conditions.
3. Summary of plant operation
The HTI plant processed approximately 22,000 tonnes of waste in 2008during 5,784 operational hours. Table 3.1 shows the waste throughputfor theyear. The wastes the plant handles are hazardous wastes that must beincinerated as they cannot be sent to landfill, and they fall into the categoriesshown in the table. Waste throughput is summarised in Figure 3.1.
The residues produced by incineration are incinerator ash and filter cake.These are non-hazardous wastes and can be sent to landfil!. Table 3.1 showsthe residues produced during 2008. These residues are analysed in theonsite laboratory before being taken to landfill. Such residues are not suitablefor recycling.
Significant outages are listed in Table 3.3; these are hours when the plant wasnot operational and were mainly due to necessary repair work. Overall, theplant was operational for 66% of the available hours in 2008.

4. Summary of plant monitoring
The site operates under a PPC permit issued by the Environment Agency andall emissions to air, water and iand are monitored throughout the year andreported to the Agency. The emission limit values in the permit are setaccording to the emission standards in the Waste Incineration Directive(2000176/EC on the incineration of waste).
Emissions to Air
Emissions to air from the flue stack are monitored using ContinuousEmissions Monitoring System (CEMS). This equipment operates continuouslyand monitors particulate matter, total organic carbon, hydrogen chloride,
) carbon monoxide, sulphur dioxide and oxides of nitrogen (NO,). The totalmasses of these pollutants emitted to air in 2008 are shown in table 4.1.

Hvdroaen Chloride 315 kaCarbon monoxide 4168 kaSulohur dioxide 195 ka
Oxides of nitroaen 17 540 ka
Table 4. 1: Conlin
Strict limits are adhered to for half hourly, hourly and daily emissions of thesubstances monitored by the GEMS, and the GEMS data is reported monthlyto the Environment Agency. An Annual Monitoring Summary for the GEMSdata is shown in Table 4.2; further detail can be found in the appendix (section8).
The GEM system reports the concentration of each emission in milligrams percubic metre (mg/m'). The annual half-hour maximum is the highest valuerecorded over any half-hour period during the year. The annual half-hourmean is the average of all the half-hour values recorded during the year. Theannual daily maximum is the highest value recorded over any 24 hour periodduring the year.
ELV stands for Emission Limit Value. Each emission to air (with the exceptionof carbon monoxide) has a half-hour average ELV, for example the limit forparticulate matter is 30 mg/m'. If the concentration of particulate matterexceeds this value over a half hour period then the emission has to bereported to the Environment Agency as an exceedance. There is also a dailyaverage ELV. For particulate matter this is 10 mg/m', and if the concentrationof particulate matter measured over a 24 hour period exceeds this value thenit must be reported to the Environment Agency as an exceedance.
The exceedances reported during 2008 are listed in section 5.

The continuous emissions monitoring system was functioning normallythroughout 2008.
Other emissions to air are monitored periodically by an external contractor.Table 4.2 shows the average results of the two biannual checks in 2008 forcadmium and thallium, mercury, other metals (antimony, arsenic, chromium,cobalt, copper, lead, manganese, nickel, tin and vanadium), dioxinsffurans,PCS's (polychlorinated biphenyls) and PAH's (polycyclic aromatichydrocarbons). Periodically monitored emissions to air are reported to theEnvironment Agency and must fall within the limits stated in the PPC permit.

Emissions to Water
Treated waste water from the HTI plant is discharged to Southampton Waterafter testing for pH, suspended solids, ammoniacal nitrogen, various metals,phosphate and temperature. The flow rate is also monitored and must remainbelow a given limit. All of these parameters are monitored continuously; Table4.3 shows the monthly average values for 2008 and (where appropriate) thetotal released to water during the year.
Spot checks are carried out bi-annually on the site's waste water. The wateris sampled and sent for independent analysis for various organic compounds.Table 4.4 shows the results for these periodically monitored emissions towater, along with the concentration limits allowed in the site's permit. Manycompounds were below the limit of detection, meaning that they were notpresent in high enough concentrations to be detected by the test method.Exceedances were recorded for atrazine and for tributyl tin and triphenyl tin(results for the two tin compounds are added together to meet oneconcentration limit); these were notified to the Environment Agency and arediscussed in section 5.
As described in section 4, the plant operates under a PPC permit which statesthe maximum allowed emission of a given substance over a half hourly, hourlyand daily period. Any emissions which exceed this limit are non-compliantand must be reported to the Environment Agency with an explanation of thelikely cause and the actions that have been taken to solve the problem. Table5.1 shows the exceedances for 2008. The table shows that five exceedanceswere reported in 2008. These were for the release of particulates and metalsto air, and for the release of organic compounds to water. The latter wasdetected by an external lab on testing a six monthly composite of waste water.A sample has been sent for re-testing as the atrazine result is suspected to beanomalous. The value recorded for tributyl tin/triphenyl tin is the same as the2006 and 2007 values but the emission limit value has been reduced thisyear, making it an exceedance.
The plant was in compliance with the permit conditions for all other emissionsto air and water.
Table 5.2 shows environmental complaints received by the Fawley site during2008. All complaints about the site are fully investigated and any findings arereported to the EA and the complainant. Note that the Fawley site consists ofthe High Temperature Incinerator covered in this performance report as wellas the Waste to Energy Incinerator, which is covered In a separate report (seesection 7).
