Stephen Othen Technical Director Fichtner Consulting Engineers Ltd Monitoring – On-site and Off-site THE GROUP

2 Issues to be Covered Monitoring of emissions to atmosphere Continuous monitoring Periodic monitoring Additional Permit Requirements Off-site monitoring Current monitoring Further monitoring pre-construction Monitoring post-operation

3 Continuous Monitoring The following substances will be monitored continuously 1.Oxides of nitrogen (as NO 2 ) 2.Sulphur dioxide 3.Carbon monoxide 4.Hydrogen chloride 5.Volatile Organic Compounds (VOCs) 6.Particulates 7.Ammonia Emission Limits set for half-hourly and daily averages. All reported to the Environment Agency WID Requirement EA Requirement

4 Periodic Monitoring The following substances will be monitored every three months 1.Dioxins and Furans 2.Mercury 3.Cadmium and Thallium 4.Antimony, Arsenic, Chromium, Cobalt, Copper, Lead, Manganese, Nickel and Vanadium 5.Hydrogen Fluoride 6.Nitrous Oxide 7.Dioxin-like PCBs 8.Polycyclic Aromatic Hydrocarbons (PAHs) WID Requirement EA Requirement

5 Additional Permit Conditions for On-Site Monitoring The Environmental Permit for the facility is likely to include the following conditions (based on other recent permits): 1.Confirm the size distribution of particulates. 2.Review techniques for the continuous monitoring of heavy metals, PAHs, dioxins and furans and dioxin-like PCBs. 3.Confirm the calibration and verification testing of the Continuous Emissions Monitoring Systems (under BS EN 14181). QAL1 – quality assurance of equipment QAL2 – quality assurance of entire installation QAL3 – confirmation of precision and accuracy AST – annual confirmation of QAL2

6 Off-site Monitoring Diffusion tube survey measuring nitrogen dioxide and sulphur dioxide. Aim is to establish baseline concentrations in the local area First year: July 2009 to July locations in total Results so far: Nitrogen dioxide around 20 µg/m 3 at rural sites and µg/m 3 at roadside sites. Highest concentrations near to the M1 and A421. Sulphur dioxide around 2-6 µg/m 3.

7 Off-site Monitoring – Locations for Year 1

8 Off-site Monitoring Diffusion tube survey measuring nitrogen dioxide and sulphur dioxide. Aim is to establish baseline concentrations in the local area. First year: July 2009 to July locations in total Second year: From July 2010 Redesigned to focus on human receptors Discontinued some ecological receptors

9 Off-site Monitoring – Locations for Year 2

10 Off-site Monitoring Diffusion tube survey measuring nitrogen dioxide and sulphur dioxide. Aim is to establish baseline concentrations in the local area. First year: July 2009 to July locations in total Second year: From July 2010 Redesigned to focus on human receptors Discontinued some ecological receptors Continuous Monitoring: Initially at Stewartby Brickworks (PM 10, PM 2.5, NO 2, SO 2, CO) Now moved to the Forest Centre car park

11 Off-site Monitoring Soil Monitoring for dioxins/furans and heavy metals. Carried out once at six sites. Results: Dioxins/Furans at around the rural baseline, with site 8 slightly high. Most metals at typical rural levels. Copper and lead slightly high at site 8. Mercury high at all sites.

12 Additional Permit Conditions for Off-Site Monitoring The Environmental Permit for the facility would normally include the following conditions (based on other recent permits): 1.Agree a programme of baseline monitoring before the plant can be commissioned. The programme shall cover periods before and after commissioning. 2.Carry out ambient air monitoring to confirm the dispersion modelling. For Rookery Pit, the current programme may satisfy (1) already.
