The STAC will be the main mechanism for coordinating multi-agency specialist advice to cover public health, environmental, scientific and technical issues. Protection of public health should be a foremost concern of STAC as part of any coordinated emergency response.
Arrangements for calling-out and supporting a STAC should be included in Strategic Coordinating Group generic plans. Detailed arrangements for scientific and technical advice are included in plans for a number of specific types of emergency - e.g. oil and chemical spill ( MCA National Contingency Plan for Marine Pollution); nuclear sites ( HSE REPPIR and NEPLG Guidance). The SCG area generic arrangements can be used in the case where specific plans are not activated.
The core composition of a STAC and the mechanism for assembling it are likely to be similar irrespective of the type of emergency. In some specific types of emergency, individual or groups of specialist advisers or other government agency advisers can support the work of the SCG. The advice from these specialist advisers must be fed to the SCG through the STAC reporting arrangements to ensure coordination of the advice.
