not discharge waste concrete slurry or wash water from concrete, or cement into the marine environment, and where practicable, site concrete and cement mixing and washing areas at least 10 metres away from the marine environment and any surface water drain to minimise the risk of run off entering the marine environment;

store, handle, transport and use fuels, lubricants, chemicals and other substances so as to prevent releases into the marine environment, including bunding or storage of 110% of the total volume of all reservoirs and containers;

store all waste in designated areas that are isolated from surface water drains and open water and are bunded;

use suitable protective sheeting to prevent dust, debris (including paints and solvents) and rebounded or windblown concrete from entering the water environment, and rebounded material must be cleared away before the sheeting is removed;

ensure that any coatings and any treatments are suitable for use in the marine environment and are used in accordance with either guidelines approved by the Health and Safety Executive or the Environment Agency;
