will have increasing implications for development in coastal
infrastructure such as transport networks (roads, ports and
airports), wastewater treatment plants and potable water
supplies, as well as creating capacity and performance issues
with stormwater and overland drainage systems.
In 2017, MfE reported a doubling in the rate of sea level rise

The area immediately surrounding the galvanising buildings is concreted. The concrete and metal yard

Wastewater from washing down the trucks (with quaternary ammonia sanitiser) and

In general, the site was managed to a good standard in relation to stormwater and wastewater
management. Stormwater was managed to avoid any contact with chemicals stored on-site
with all wastewater 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 period under review, no sampling of the novaflow pipe containing leachate was

The AEE must as a minimum adequately demonstrate that:
The geologic formation into which the wastewaters are injected is sufficiently
porous and permeable so that the wastewater can enter the rock formation
without an excessive build up of pressure;
