How your waste can pollute the
environment
Any material or substance left uncovered or on the
ground outside can flow or be washed by rainwater
into a nearby stormwater drain where it will result in
the pollution of the local stream and/or the coast.
Wastewater from blasting operations contains a number
of substances that can pollute our environment. These
include sediment, fuel

any significant effects of stormwater or wastewater discharges from the Fitzroy
industrial area on the macroinvertebrate communities of the Waiwhakaiho River. The results from the
Mangaone Stream exhibited the expected and typical downstream decrease in MCI scores, however in this
instance noticeable deterioration of SQMCI scores were noted in the middle to lower reaches of the
Mangaone Stream during the summer survey.

Nova Energy holds water discharge permit 4560-2 to discharge wastewater from filter backwashing and
tank cleaning into the Waitara River. This permit was issued by the Council on 7 January 2003 under Section
87(e) of the RMA to Shell Todd Oil Services Ltd. It was transferred to Todd Taranaki Ltd on 31 May 2006,
then to Bay of Plenty Energy on 15 June 2011 and to Nova Energy on 8 April 2013. It is due to expire on 1
June 2021.
There are three special conditions attached to this
the period under review included two inspections
and one investigation. A total of nine water samples were collected for physicochemical
analyses during the reported period.
Stormwater was managed to avoid contact with chemicals stored on-site. All wastewater was
either disposed of directly to trade waste or temporarily stored in the bunded area of the site
before being removed off-site for disposal or recycling at an approved facility.
During the spring survey sampling was limited due
Eltham wastewater treatment plant/Eltham landfill combined
monitoring programme.
Historically the water quality in the Mangawhero Stream was quite poor due to the discharges from the
Eltham wastewater treatment plant and it was difficult to fully access any impact from the landfill on the
stream. Generally no deterioration in water quality was found when comparing upstream and downstream
sites.
Now that the Eltham wastewater treatment plant pumps its effluent to the Hawera wastewater
manufacturing
wastewater is treated on-site and discharged to the Tasman Sea via a marine outfall. The wastewater
discharge infrastructure associated with Fonterra's Whareroa site is also utilised by South Taranaki
District Council for the discharge of municipal wastewater from the Hawera township.

bacteriological sampling at four sites at Urenui and five sites at
Onaero.
The monitoring showed that the wastewater treatment systems at the beach camps did not adversely affect
the water quality of the local freshwater and coastal environments. Although high bacteriological results
were returned from the water quality sampling efforts, these counts were attributed to surface runoff
draining the upstream agricultural catchment, following the rains that preceded the sampling.
