The location of these monitors can be found in Appendix A – MTW Monitoring Location Plan. It should be noted that the Depositional Dust and Total Suspended Particulates monitoring networks are common to MTW, and reported against both Environment Protection Licences 1376 & 1976. 2.1 2.1.1 Depositional Dust Monitoring. Depositional Dust Results Results of Depositional Dust Monitoring (WML EPL 1376 Monitoring Point 2, Condition M2.2), (MTO EPL 1976 Monitoring Point 1, Condition M2.2) are shown in Table 1. Where samples have been identified as contaminated, these are assessed for inclusion in annual average compliance assessment. The outcomes of annual average compliance assessment will be reported in the Annual Review. The last day of sampling occurred on 20 February 2015, the data was obtained on 12 March 2015.
