Road drains and surface water gullies generally discharge into controlled
waters and should be treated as such.
The Water Resources Act 1991, together with changes under this Act by the
Water Act 2003, requires consents to be obtained for any discharges to
controlled waters. The Land Drainage Act 1991 states that consent (now known
as Flood Defence Consent, FDC) will be required for works affecting drainage
ditches along the route. Applications to the Competent Authority are
required, which is generally the Environment Agency, but can, under some
circumstances, be the controlling Internal Drainage Board (IDB).
F1.6 THE FRESHWATER FISH DIRECTIVE (78/659/EEC) AND THE SURFACE WATERS
(FISHLIFE) (CLASSIFICATION) (AMENDMENT) REGULATIONS, 2003
The Directive and regulations aim to protect surface waters identified as being
of suitable, or potentially suitable, quality for sustaining fish populations.
Objectives and parameters for salmonid (1) and cyprinid (2) waters (and waters
identified as being of potential suitability) are also set. The Surface Waters
(Fishlife) (Classification) Regulations, 1997 represented the original transposition
of the Directive in the UK. The 2003 amendment regulations transpose the
Directive, which will be repealed in 2013 by the WFD.
F1.7 THE GROUNDWATER DIRECTIVE (80/68/EEC) AND THE GROUNDWATER
REGULATIONS, 1998
Directive 2006/118/EC on the protection of groundwater against pollution
and deterioration was provided for by Article 17 of the WFD. This Directive
supplements the general rules for the protection of groundwater established
through WFD in replacement of the Groundwater Directive (80/68/EEC).
The new Daughter Directive sets safety values for various polluting
substances, introducing criteria for quality standards, guidelines for the
establishment of threshold values and procedures for assessing groundwater
status. The Directive entered into force as of December 2008 with member
states having a national transposition deadline of January 2009. The
Groundwater Directive represents the third Directive set to be repealed by the
WFD in 2013.
F1.8 SOURCE PROTECTION ZONES
The vulnerability of groundwater to pollution is dependent on the presence
and nature of the overlying soils and drift deposits, the geology and the depth
to the water table. This will determine the rate at which a contaminant can
migrate into the water. The Environment Agency has identified Source
(1) Salmonid is a term applied to waters suitable for supporting fish from the family Salmonidae. This family includes
anadromous, or migratory, species including salmon and some species of trout.
(2) Cyprinid is a term used to describe waters suitable for fish from the family Cyprinidae, which includes coarse fish such
as carp, roach and tench.
