SERVICES & ORGANISATION COMMITTEE MEETING REPORT                                           12 OCTOBER 2021


Quarterly onsite meetings between Council officers, LMS Energy and Council’s ZEN representatives
have continued. Current trends in gas volume, operational status of wells, future plans for the gas
network and heat mapping areas of landfill with good/poor gas capture are analysed to direct
increased future volume of methane capture.
Environmental Compliance
A total of 1038.5mm of rainfall was recorded at the Landfill throughout the reporting period, a majority
of which fell in March 2021. No major environmental incidents occurred as a result of the wet weather
events and no releases of nutrients or leachate were observed.

 19 January       Dissolved Oxygen             This noncompliance is not considered indicative of environmental
 2021             compliance limit             harm as all other parameters were compliant and no adverse
                  exceedance                   impacts were observed onsite. The Department of Environment
                  following 59mm of            and Science was notified. No further action was required, and this
                  rainfall                     matter was closed without any enforcement action.
 31 March         Total Suspended              This event was part of a weather event causing mass flooding to a
 2021             Solids and dissolved         lot of the east coast. Visual inspections were undertaken once
                  oxygen compliance            flooding had subsided to assess whether any sediment deposits
                  limits exceeded              on vegetation and/or signs of environmental harm were present.
                  following 180mm of           The Department of Environment and Science was notified. No
                  rainfall over 4 days         further action was required, and this matter was closed without
                                               any enforcement action.

                  Solids and dissolved         east coast of Australia the week prior. Exceedances were
                  oxygen compliance            negligible, however, a follow-up inspection was undertaken
                  limits exceeded              confirming no evidence of environmental impacts at the discharge
                  following 115mm of           location or downstream. The Department of Environment and
                  rainfall over 3 days         Science was notified. No further action was required, and this
                                               matter was closed without any enforcement action.
 14 May 2021      Total Suspended              Exceedance of compliance limit was negligible. Follow-up
                  Solids compliance            inspection was undertaken to confirm no evidence of
                  limit exceeded               environmental impacts at the discharge location or downstream.
                  following 116mm of           HES basin planned for full clean out and maintenance works in
                  rainfall over 3 days         upcoming dry months. The Department of Environment and
