1. INTRODUCTION

As per conditions M1 to M7 of Environment Protection Licence (EPL) 3607, this report summarises environmental monitoring

results for Springvale Coal Services for the period July 2015. Monitoring sites are shown on the Lambert’s Gully Mine Site

section of the Centennial website and in Appendix 1. Although EPL 3607 also covers Springvale Colliery, monitoring data from

this site will be reported separately from this Springvale Coal Services Monitoring Report.

A summary of the licence information is provided in the following tables. Table 1 shows the licence information and Table 2

summarises the parameters, units and dates of sampling for monitoring data for the reporting period. It should be noted that

there was a variation to EPL 3607 issued on 12 August 2014.

2. WEATHER

A summary of rainfall data recorded at the on-site meteorological monitoring station during the July 2015 reporting period is

shown in Table 3 below.

3. AIR QUALITY MONITORING

The air quality monitoring results for the reporting period are summarised below.

3.1 Depositional Dust

Depositional dust (g/m2/month) results (insoluble solids) for the year to date are shown in Table 4.

CS-D5 (Point 8-5) BD 0.5 0.7 0.4 0.4 0.4 0.6

CS-D# – Coal Services Dust Gauge

EPL 3607 does not include a licence limit for depositional dust, however a rolling average air quality criteria of 4 g/m2/mth is

commonly used for comparison purposes. Dust monitoring data indicates that dust deposition results for July 2015 range from

below 0.6 at CS_D5 to 6.4 g/m2/month at CS_D3.

4. SURFACE WATER QUALITY

Surface water pH, total suspended solids (TSS mg/L), electrical conductivity (EC µS/cm), oil and grease (mg/L), filterable iron,

filterable manganese are monitored at LDP006 as indicated on the Environmental Monitoring location figure, located in

Appendix 1 and on the Centennial website. LDP007 is also part of the EPL however this monitoring location is the discharge

from a sump and generally has no discharge.

5. INCIDENTS

There were no incidents recorded during the reporting period.

6. NOISE MONITORING

Noise monitoring for the operation is conducted at monitoring locations detailed in Appendix 2.

Activities from WCS complied with the relevant development consent noise limits during monitoring on 20

and 21 July 2015 at all monitoring locations except NM7 during the night period.

WCS noise levels at NM7 exceeded the LA1,1minute criteria by 3 dB during the night period on 21 July 2015.

Impact noises as a result of maintenance works being carried out on the WCS overland conveyors were generally

responsible for the site only noise levels.

7. COMPLAINTS

There were no community complaints during the reporting period.

Notes:

1. Criterion may or may not apply due to rounding of meteorological data values;

2. Noise emission limits do not apply during the following meteorological conditions: wind speeds greater than 3 metres

per second (at a height of 10 metres); or temperature inversion conditions greater than 3oC/100m;

3. Estimated or measured LAeq,15min attributed to WCS;

4. Bolded results in red indicate exceedance of criteria; and

5. NA in exceedance column means atmospheric conditions outside conditions specified in development consent and so

criterion is not applicable.
