It describes the requirement for the assessment of cumulative effects, the guidance available for completing the assessment in relation to Nationally Significant Infrastructure Projects (NSIP) and presents the results of the assessment. 14.1.2 Cumulative effects are the result of multiple actions on environmental receptors or resources. There are principally two types of cumulative effect: . The combined action of a number of different environmental topic specific effects upon a single resource/receptor (Intra-Project Effects); and . The combined action of a number of different projects, in combination with the project being assessed, on a single resource/receptor (Inter-Project Effects). 14.1.3 This chapter should be read in conjunction with Figure 14.1. 14.2 Regulatory and Planning Policy Framework 14.2.1 Schedule 4 of the Infrastructure Planning (Environmental Impact Assessment (EIA)) Regulations 2009 as amended states that an Environmental Statement (ES) should include: ‘A description of the likely significant effects of the development on the environment, which should cover the direct effects and any indirect, secondary, cumulative, short, medium and long-term permanent and temporary, positive and negative effects of the development, resulting from: a) The existence of the development; b) The use of natural resources; or c) The emission of pollutants, the creation of nuisances and the elimination of waste. And the description by the applicant of the forecasting methods used to assess the effects on the environment.’ 14.2.2 The Overarching National Policy Statement for Energy (NPS EN-1) states the following in relation to requirements for the assessment of cumulative effects: ‘When considering cumulative effects, the ES should provide information on how the effects of the applicant’s proposal would combine and interact with the effects of other developments (including projects for which consent has been sought or granted, as well as those already in existence).’ The River Humber Gas Pipeline Replacement Project Page 1 Environmental Statement Volume 6 Environmental Statement Document 6.14 14.3 Methodology Relevant Guidance 14.3.1 A number of sources provide guidance on how to complete a Cumulative Effects Assessment. 14.3.2 According to the Design Manual for Roads and Bridges (DMRB), Volume 11, Section 2, Part 5 (HA 205/08) ‘Assessment and Management of Environmental Effects’, cumulative effects result from multiple actions on receptors and resources over time and are generally additive or interactive (synergistic) in nature. Cumulative effects can also be considered as impacts resulting from incremental changes caused by other past, present or reasonably foreseeable actions together with the project.’ 14.3.3 The European Commission has published the ‘Guidelines for the Assessment of Indirect and Cumulative Impacts as well as Impact Interactions. Prepared for the European Commission, EC DG X1 Environment, Nuclear Safety and Civil Protection’ (Hyder Consulting UK Limited, 1999), which provides information on methods, the assessment process and information needed to assess the impacts. 14.3.4 The Planning Inspectorate (PINS) Advice Note 9 ‘The Rochdale Envelope’ (2011) also provides advice in relation to the assessment of cumulative effects stating: “The potential cumulative impacts with other major developments will also need to be carefully identified such that the likely significant impacts can be shown to have been identified and assessed against the baseline position (which would include built and operational development). In assessing cumulative impacts, other major development should be identified through consultation with local planning authorities and other relevant authorities on the basis of those that are: . Under construction; . Permitted application(s), but not yet implemented; . Submitted application(s) not yet determined; . Projects on the Planning Inspectorate’s Programme of Projects; . Identified in the relevant Development Plan (and emerging Development Plans – with appropriate weight being given as they move closer
