and the recirculation system.
During the 2019-2020 year, there was a reduction in the use of the Fire Training Centre and the recirculation

Results of consent holder monitoring
2.1.3.1 Stormwater monitoring by OMV
OMV monitors the combined stormwater discharge from the site, with sampling triggered by rainfall events.
Table 4 shows the results obtained during the 2018-2019 monitoring year. In all samples pH, hydrocarbons
and chloride levels were all within/below the limits set by consents 5997-1 and 6269-1, and were indicative
of a consistently clean discharge. The level of suspended solids was slightly above the allowable limit
