(a)	The following special arrangements shall apply—

(i)	For pyrolysis, reference oxygen content does not apply.

(ii)	The facility shall be designed, equipped, built and operated in such a way so as to prevent the emissions into the air giving rise to significant ground-level air pollution (i.e. leading to the exceedance of an accepted ambient air quality threshold standard).

(iii)

Monitoring equipment shall be installed and acceptable techniques used in order to accurately monitor the parameters, conditions and mass concentrations relevant to the co-processing of AFR and incineration of waste.

(iv)	All continuous, on-line emission monitoring results must be reported as a Daily Average concentration expressed as mg/Nm3, and at 'normalised' conditions of 10% O2, 101.3 kPa, 273 K / 0 °C,dry gas.

(v)	Discontinuous (periodic) emission monitoring results must be expressed as mg/Nm3, or ng/Nm3 1-TEQ for PCDD/PCDF, and at 'normalised' conditions of 10% O2, 101.3 kPa, 273 K / 0 °C, dry gas.

(vi)	Exit gas temperatures must be maintained below 200 °C.

(vii)

Pollution control devices (exhaust gas cooling and bag filter or ESP) must have a daily availability of 98% (i.e. maximum downtime of 2% or 30 minutes per running 24 hours). The cumulative annual downtime (total downtime over a one year period) may however not exceed 60 hours (0.685 % per annum).

(viii)

Continuous, on-line measurement of the following emissions and operating parameters is required:

•	Particulate matter (total particulate);

•

02;

•

CO;

•

NOx;

•

SO2;

•

HCI;

•

HF;

•

VOC/TOC;

•	Emission exhaust volume (e.g. Nm3/hr) and flow rate (e.g. m/s);

•	Water vapour content of exhaust gas (humidity);

•	Exhaust gas temperature;

•	Internal process temperature/s;

•	Pressure; and

•	Availability of air pollution control equipment (including exit gas cooling).

(ix)

Appropriate installation and functioning of automated, continuous monitoring equipment for emissions to air; which are subject to quality control and to an annual surveillance test. Independent accredited calibration must be undertaken by means of parallel measurements with the reference methods, at a frequency as per the requirements of the equipment, but as a minimum every 3 years.

(x)

Periodic measurements of heavy metals and dioxin and furan emissions must be undertaken, using national (if available) or internationally acceptable methods, by independent/external, accredited specialists twice during the first 12 months of waste incineration/AFR co-processing, and annually thereafter.

(xi)

Average emission values for heavy metals are to be measured over a minimum sample period of 60 minutes to obtain a representative sample, and a maximum of 8 hours, and the average values for dioxins and furans (expressed as 1-TEQ) over a sample period of a minimum of 60 minutes and maximum of 8 hours.

(xii)

Periodic measurements of heavy metals and dioxins and furans are to be carried out representatively to provide accurate and scientifically correct emission data and results, and sampling and analysis must be carried out by independent, accredited laboratories.

(xiii)

To ensure valid monitoring results are obtained, no more than five half-hourly average values in any day, and no more than ten daily average values per year, may be discarded due to malfunction or maintenance of the continuous measurement system.

(xiv)

All measurement results must be recorded, processed and presented in an appropriate manner in a Quarterly Emissions Monitoring Report in order to enable verification of compliance with permitted operating conditions and air emission standards. Quarterly Emission Monitoring Reports must include, amongst others:

•	Daily average results of all continuous, on-line emission monitoring parameters, reported on line graphs that include individual, daily average data points, and indicating the relevant air emission limit if applicable;

•	Results of all continuous, on-line operational monitoring parameters, reported on line graphs that correspond in scale with the emission monitoring results;

•	Results of periodic emission measurements of heavy metals, and dioxins and furans;

•	Confirmation of residence times and temperatures of specific wastes co-processed as determined by the specific feed points, plant dimensions and material and gas flow rates;

•	Discussion on availability or air pollution control equipment, together with reasons for and management of downtime;

•	All relevant results must be compared with baseline measurements taken prior to the co-processing of AFR or hazardous waste; and

•	Detailed evaluation and discussion of any non-compliance during the reporting period.

(xv)

Treatment of High Level POPs Containing Waste (as defined by the Stockholm and Basel Conventions) are to be preceded by an independently monitored Performance Verification Test to determine the Destruction Efficiency (DE) and Destruction and Removal Efficiency (DRE) of principal organic hazardous compounds (POHC) using a suitable verification compound (e.g. trichloroethane) .

(xvi)

A plan for conducting a Performance Verification Test must be submitted to the relevant Government Department/s at least 3 months prior to the commencement of such a test, and must include, amongst others, the following:

•	Motivation for why the plant should be used for treatment of High Level POPs;

•	A feasibility study showing that the plant is technically qualified;

•	Planned date for commencement of the test and expected duration;

•	Details on the waste to be co-processed during the test, including source, volume, composition etc.;

•	Motivation for the particular choice of waste and its suitability in providing an accurate and representative indication of the plant's DE and DRE, and therefore suitability to treat High Level POPs Containing Waste;

•	Extension of monitoring regime to include Chlorobenzenes, HCB, PCBs, Benzene, Toluene, Xylenes, PAHs, and NH3;

•	Monitoring and analysis to be conducted, the associated methodologies and independent parties responsible for monitoring.

(xvii)

A detailed, independent report documenting and interpreting the results of the Performance Verification Test must be compiled. As a minimum, a DE/DRE of 99.9999% would be required, as well as compliance with Air Emission Standards.

(xviii)

An Air Quality Improvement Plan for achieving emission limits over time must be developed if transitional arrangements apply to compliance with emission standards.

(xix)

Compliance time frames for health care risk waste incineration will be as specified in paragraphs (8); (9); and (10) unless specific compliance time frames for health care risk waste incineration have been set under health care risk waste regulations, in which case, the specific compliance time frames for health care risk waste incineration set under health care risk waste regulations shall apply.

(xx)	Continuous emission monitoring for Health Care Risk Incinerators shall be complied with by 31 March 2014.

(xxi)

Combustion of solid, liquid and gaseous waste materials in installations primarily used for steam for steam raising or electricity generation must comply with the emission standards of this sub-category.
