AQMA Feasibility Assessment
A2 – Keycol Hill and Key Street, Swale

Note: “R” = roadside. Bold denotes exceedance of the AQS.

3.14 The data in Table 3.5 show that annual mean PM10 in other SBC AQMAs are
consistently below the AQS. The highest concentrations was on St Paul’s Street
in 2018, 29.7% below the AQS. These monitors are a significant distance from
Key Street and Keycol Hill and are therefore not considered representative of
local conditions.
Non-Automatic Monitoring

NO2

3.15 SBC also operate a non-automatic, NO2 diffusion tube monitoring network
across the borough. The most recent available monitoring data for diffusion
tubes located along the A2 are included in Table 3.6.
