Welcome to the H1 Software

Welcome H1 Version Welcome to the H1 Software 2.01- May 2010 Introduction This version of the tool accompanies Horizontal Guidnace Note 1 Version 2.0 April 2010 (As Amended) Important Notes: This software tool can be used to complete most of the modules within H1. However, further information may need to be provided in the following areas: - detailed assessment of fate and effects, where required - decision-making trails for the comparison and ranking of options This software provides a general structure for assessing costs and environmental impacts. You may need to decide the best way to apply this structure to fit the nature and pattern of your operation, in particular: - where load is variable, such as seasonal or demand-led operations - where a number of processes are conducted at the same time, such as integrated operations - where a number of products are made, with possible differences in unit operations and release points employed - where fugitive or potential emergency releases are of particular interest Information in this database will be used to determine your EPR permit, therefore to get the most from this software tool, you should: - read the introduction to the H1 guidance, to understand the basic principles, module structure and methods - use the HELP boxes and refer to the H1 guidance as you progress to ensure that the data you input is representative and accurate - use the comments boxes to clarify assumptions and data sources Some basic instructions for using the software tool are provided on our web site at www.environment-agency.gov.uk/h1softwareguidance The application has been optimised for a screen resolution of 800 x 600 Version 2.01 31 May 2010 In conjunction with: www.ability-software.co.uk

Introduction, Module 1 module 1 Introduction to Module 1 Module 1: Describe the Scope and Options The aim of this module is to: - state the OBJECTIVES of the assessment - in the case of ENVIRONMENTAL ASSESSMENT of the whole installation, describe the scope of the activities to be included in the assessment; - in the case of OPTIONS APPRAISALS, identify candidate options for BAT by considering all relevant techniques to prevent and minimise pollution and the scope of activities covered by the techniques. Depending on the reason for the assessment, you will need to complete different modules of the guidance. The software will automatically select the required modules according to the responses you enter. NOTE: If you are going to complete more than one assessment or appraisal, make sure that you create a copy of the H1 file for each new assessment BEFORE you begin to input data. This is because Microsoft Access automatically saves changes to the current file you are using, rather than allowing you to save your changes at the end of your work. TO CONTINUE WITH MODULE 1, PRESS "NEXT".

Describe the Objectives Describe the Objectives Depending on the reason for the assessment, you will need to complete different modules of the guidance. Select the type of assessment: a) to conduct a costs/benefits OPTIONS APPRAISAL to determine BAT for selected releases from an installation Do modules 1,2, 3 and 4 and continue with 5 and 6 if necessary b) to carry out an ENVIRONMENTAL ASSESSMENT of the emissions resulting from the installation as a whole Do modules 1, 2 and 3 only 1.1 Briefly summarise the objectives and reason for the assessment in terms of the main environmental impacts or emissions to be controlled: ERF Environmental Assessment including Air Quality & GWP100 as CO2e [plus nitrous oxide (N2O)]

Scope of Environmental Assessment Scope of Environmental Assessment List the activities included in the assessment This should include all the activities in your permit, broken down into the basic process steps, such as: raw materials storage, handling, processing, emission control, waste treatment etc. as appropriate.

Number Activity 1 Releases to the environment from combustion, energy use, GWP [CO2e & Nitrous Oxides, N2O] and impact on environment Comments

Module 2 - Emissions Inventory module 2 Introduction to Module 2 Module 2: Emissions Inventory The aim of this module is to produce an inventory of sources and releases of polluting substances from each option. This is used as the basis for the subsequent evaluation of environmental impacts. For this module you will require information on: - release points and sources of emissions to all media - concentration and mass rate of emitted substances - frequency and duration of emissions and how these relate to long term and short term effects IMPORTANT NOTES - you may need to consider a suitable method for assessment of groups of pollutants, such as VOCs, heavy metals, uncharacterised liquid effluents, etc (see H1 guidance for details).

Module 3 - Quantify Impacts module 3 Introduction to Module 3 Module 3: Quantify Impacts The aim of this module is to quantify the effects on the environment of the emissions listed in the inventory in module 2. This guidance provides methods for assessing the ten main environmental considerations of most relevance to the PPC regime. Your emissions may not result in effects to all ten of these considerations, and the module allows you to screen out any that are not relevant. The emissions you entered in module 2 are automatically brought forward for assessment into each environmental consideration that is relevant for that type of emission (e.g. an emission may have more than one type of effect). This module allows you to screen out any emissions that are insignificant, and to identify those emissions where further, detailed assessment of the potential environemtnal impact may be required. IMPORTANT NOTE This software tool only completes PART of the requirements for module 3, as described above. Depending upon the degree of risk to the environment presented by the emissions, the operator may need to do further, detailed assessment of the potential effects using methodologies that are not provided here. This information should be submitted separately, as indicated within this module. TO CONTINUE WITH MODULE 3, PRESS "NEXT".
