[email protected] Report Reference Knowsley 19 (2nd Version) number Date July 2020 LAQM Annual Status Report 2019 Knowsley Metropolitan Borough Council July 2020 Addendum For transparency, the main report initially submitted is unchanged. This addendum has been produced on request of the LAQM Helpdesk due to new findings as discussed below. The information in this addendum section will replace the relevant parts of the main report. Following the completion of the 2019 ASR, one site (site 3) showed there to be a borderline exceedance of the Air Quality Objective (AQO) for nitrogen dioxide, of 41.7 μg/m3, when compared to the annual AQO of 40 μg/m3. In our conclusions we therefore discussed carrying out a detailed assessment to determine if we needed to declare an AQMA. Prior to the detailed assessment being carried out checks were made at the site to ensure all the measurements used were correct. Through this check we discovered that the measurements used in the report were slightly different from the actual site measurements. Using these new measurements has shown that the predicted level at the sensitive receptor has changed. In fact, when using the correct measurements the result for site 3 has reduced to 40.6 μg/m3.
