UK Regulations

Consent limits for discharge to public drains in the United Kingdom are set by the eight regional water companies. In general these limits are established on a case-by-case basis rather than by the imposition of overall national or local standards. In determining the limits in individual cases, consideration is given not only to the concentration of individual pollutants but also to factors such as location, total volume of discharge, and the capacity of, and methods used by, local treatment works.

Discharge to streams, rivers, and coastal waters is controlled by the National Rivers Authority.

It should be borne in mind that the transport and labeling of solid and liquid wastes is also regulated. Solid and semisolid waste arises from the neutralization and precipitation of effluent in in-house treatment facilities and also from the sludge generated as a by-product of heavy metal phosphating processes. This sludge is removed on a continuous or batch basis and is usually disposed of to landfill sites. However, before this is done, under the Control of Pollution Act of 1974, a disposal license must be obtained from the local disposal authority, which will require detailed data on the nature of the waste.

The conveyance and labeling of hazardous wastes is covered by:

• Dangerous Substances (Conveyed by Road in Tanks and Tank Containers) Regulations, 1981

• Road Traffic (Carriage of Dangerous Substances in Packages) Regulations, 1986

• Classification, Packaging, and Labeling of Dangerous Substances Regulations, 1984
