H1 Horizontal Guidance Note : Assessment
& Appraisal of BAT
This Guidance is one of a series of Horizontal Guides covering
all of the industrial (or agricultural) sectors that fall under
IPPC. In common with most of the IPPC guidance it is joint guidance
produced by the Environment Agency, SEPA and the Northern Ireland
Environment and Heritage Service NIEHS).
Integrated Pollution Prevention and Control (IPPC) is a
regulatory system that employs an integrated approach to control
the environmental impacts of certain industrial activities. It
involves determining the appropriate controls to protect the
environment through a single permitting process. Amongst certain
other requirements, to gain a Permit Operators will have to show
that:
- they have developed proposals to apply the 'Best Available
Techniques' (BAT), taking account of relevant local factors;
and
- that no significant pollution is caused.
The purpose of this IPPC Horizontal Guidance Note for
Environmental Assessment and Appraisal of BAT is to provide a
methodology to assist Applicants in responding to the requirements
described above and in the IPPC Sector and General Guidance Notes.
In particular, this note provides:
- methods for quantifying environmental impacts to all
media;
- a method for calculating costs of environmental protection
techniques;
- guidelines on resolving cross media conflicts and making cost /
benefit judgements.
The methodology can be used either:
a) to conduct an OPTIONS APPRAISAL of candidate techniques to
determine BAT to control specific emissions from an installation,
particularly in cases where:
- deviation from indicative BAT in Guidance Notes is
proposed;
- several candidate Best Available Techniques exist; or
- no indicative BAT is provided in Guidance Notes.
b) to carry out an ENVIRONMENTAL assessment of the overall
impact of the emissions resulting from the installation as a whole,
in order to:
- confirm that the emissions are acceptable (ie do not cause
significant pollution); and
- identify priority emissions or environmental risks for further
improvement.
