The purpose of horizontal guidance is to provide information relevant to all sectors regulated under EPR. For example, noise, odour, energy efficiency, or protection of land.

H1 Environmental Risks Assessment
This guidance will help you assess risks to the environment and human health when applying for a bespoke permit under the Environmental Permitting Regulations 2010. However, this guide does not apply to radioactive substance activities.
The H1 Environmental Risk Assessment framework consists of an overview guide and a set of supporting technical annexes (a to k) for specific risks. No operator needs to complete all annexes. Everybody must read the overview and then select the appropriate annex or annexes.
New H1 software tool
The H1 software tool has been modified to reflect comments received from the 2010 H1 public consultation and changes brought in with the Environmental Permitting Regulations (2010). The tool is a work in progress. This latest version (2.4) contains further improvements:
If you are having difficulty opening the H1 software tool, then you may be able to view it via this Microsoft Office website:
Consultation on the hierarchy for the derivation of new Environmental Assessment Levels
The number of substances now assigned an Environment Assessment Level has declined by over 70 per cent since 2008. The previous hierarchy used Expert Panel on Air Quality Standards (EPAQS), the World Health Organization (WHO), EU Limit Values and values derived from Occupational Exposure Limits (OELs). Following a review by the Health and Safety Executive, the robust nature of some OELs has been questioned. This has resulted in the need for a new methodology to derive new Environmental Assessment Levels for substances which no longer possess them.
This consultation proposes a hierarchy which contains new methodologies that no longer rely on occupational exposure as the basis for their calculation. We welcome your views on these proposals. You can view all of the consultation documents on the consultation web page.
