Waste incineration / EfW
permits, stack limits, CARs, waste inputs, ash/APC residues, abnormal events, CO₂
Candidate source investigations
AQ26 now treats incinerators as one candidate source class among multiple plausible contributors. This makes the project more defensible, more useful and less vulnerable to confirmation-bias criticism.
Source classes
Road traffic
NO₂/PM near roads, fleet mix, congestion, street canyon and receptor exposure
Industry / large point sources
NAEI point-source context, permits, emissions returns, enforcement
Ports / shipping
NOx/SOx/PM context, harbour activity, wind direction and receptors
Landfill / waste transfer
odour, methane, bioaerosols, leachate and waste movements
Agriculture
ammonia, secondary particulate chemistry and rural background
Domestic burning
PM2.5, PAHs, seasonal evening patterns and local authority controls
Meteorology / long-range transport
inversions, wind sector, Saharan dust, regional episodes and CAMS context
Decision rule
A source class moves from candidate to stronger interpretation only after original-source review, monitor role, time alignment, meteorology, comparator context and reviewer challenge gates are satisfied.
