An outline Construction Environmental Management Plan provides a framework from which a final Construction Environmental Management Plan (CEMP) will be developed to avoid, minimise or mitigate any construction effects on the environment.
Such measures should be incorporated in method statements which should identify the perceived risks to the aquatic environment, identify potential pollution pathways, and the mitigation measures to be employed which will negate the risk to any aquatic environment. For example;
Details of all proposed excavations and construction.
Details of all areas to be used for the storage of substrate/spoil including a suitable buffer between location for storage of excavated spoil and construction materials and any watercourses or surface drain present on site or adjacent to site.
Details of the pollution prevention measures to be employed during construction and operation.
Detailed drawing plans, demonstrating a suitable buffer between location of refuelling, storage of oil/fuel, concrete mixing and washing areas and any watercourses or surface drain present on site or adjacent to site (at least 10m)
A proposed storm drainage plan designed to the principles of Sustainable Drainage Systems (SuDS) in order to minimise the polluting effects of storm water on waterways. Construction of SuDS should comply with the design and construction standards as set out in The SuDS Manual - Construction Industry Research and Information Association (CIRIA) Report C753 (2015).
Regular inspections of machinery onsite.
Emergency spill procedures in place.
This list is not exhaustive but should merely be used as a starting point for considerations to be made.
