SCAIL Agriculture decision flow chart Figure 2 shows the flow diagram of the SCAIL agriculture tool and the decisions that may be taken in carrying out an environmental assessment Since the tool compares a number of metrics for habitats or human health obtaining no exceedance on all limits may be difficult Where environmental standards are already exceeded by the background or the new installation results in an exceedance you should consult the relevant regulatory guidance for further action In addition for emissions of ammonia where a sensitive receptor is located within 250 metres of the installation the following guidance must be followed e For intensive farming sites that are regulated under the Environmental Permitting Regulations EPR in England and Wales PPC permitted sites in Scotland IPPC in Northern Ireland and with distances to the nearest sensitive receptor of less than 250m applicants must go straight to undertaking detailed modelling e For non EPR PPC IPPC sites with distances to the nearest sensitive receptor between 100 250m SCAIL can be used and then advice must be sought from the regulator for clarification on whether detailed modelling is required e For sites with distances to the nearest sensitive receptor of less than 100m detailed modelling will be required SCAIL Agriculture User Guide March 2014 8 1 0 CONFIGURATION Select Conservative or Realistic mode Add details ofthe Countryto be a ed
