What is a H1 Risk Assessment?

When applying for a standard permit, the Environment Agency have done most of the risk assessment for you. When you apply for a bespoke permit their maybe some grey areas with regards to risk, as such a H1 Risk Assessment may be required. A H1 Risk Assessment is a method for gauging risks of certain aspects of your activities. An example:

An operator is recycling plastics, and there are several emissions points where vapours and particulates from the recycling process are escaping in to the air, of particular concern may be VOCs;

Bromodichloromethane

1,1-Dichloroethane


Tetrachloromethane


The above three VOCs are being released and it unclear whether the levels are safe. Do they pose a risk to the environment? Do they pose a risk to nearby residents? This is where the H1 Risk Assessment comes in to play.

By assessing volumes, concentrations, dilution and sensitivity of receptors a risk level can be deduced. This information can be used to;

1 - Help Support an application for an Environmental Permit

2 - Lessen Monitoring Requirements for a Particular Substance
Environmental Permitting - OPRA - Dice

There are four major steps in completing an H1 Risk Assessment, the first is to identify the risks associated with your permitted activity, the second is to assess those risks, the third to decide on appropriate measures (and to justify those measures, and finally to present your findings to the Regulator (Environment Agency).
