Both fall in band A, meaning ammonia is likely to have little to no effect on all but the most sensitive species. Modelled estimates support monitoring results, with approximately 82% of streams and

overabundance of algae and aquatic weeds, impact on the growth of sensitive species, or even become toxic to freshwater organisms. For ammonia, modelling suggests that all streams fall in band A (92%) or band B (8%) (Figure 4). Ammonia is expected to have little to no toxic effect on all but the most sensitive species. For nitrate, around 12% of streams fall within band A and aquatic species are unlikely to experience the effects of nitrate. The majority of streams fall into band B (88%) (Figure

material deposited on the ground in the log and coal storage areas. When it rains this material washes into the stormwater system, and discharges into the harbour via the numerous piped outlets (Figure 2). In order to minimise deleterious effects on the receiving environment, Port Taranaki Ltd (Port Taranaki) have implemented a number of preventative measures since 2012, including upgrading the stormwater treatment system and improving stormwater management procedures. This work is ongoing, as log

sites are monitored for ammonia. Three out of four sites fall within band A and one site in band B. At these sites, ammonia is likely to have little to no effect on all but the most sensitive species. Modelled estimates support the monitored results, with approximately 68% in band A and 32% in band B (Figure 4). Four sites are monitored for nitrate, all of which fall in band A. At these sites, nitrate is likely to have little to no effect on aquatic life. Modelled estimates largely
