Sustainability appraisal and strategic environmental assessment

Sustainability Appraisal (SA) is required under the Planning and Compulsory Purchase Act 2004 for all Development Plan Documents (DPDs) and Supplementary Planning Documents (SPDs). The EU Strategic Development Directive also requires a Strategic Environmental Assessment (SEA) to be carried out on certain types of plans with significant environmental effects.

Both processes are undertaken during the preparation of a plan or strategy to aid the implementation of sustainable development. The main difference between them is that while SEA has more of an environmental focus, SA includes greater coverage of the social and economic aspects of sustainable development. Although SA and SEA are distinct requirements, government guidance has recommended a single appraisal process.

Suffolk approach to Sustainability Appraisal

The Suffolk Local Planning Authorities have been working together for 10 years to assess the impact of planning policies and decisions on progress towards sustainable development, through the Suffolk Sustainability Appraisal Group (SSAG). The group continues to produce annual monitoring information and a leaflet for the project "Suffolk's Environment towards sustainable development", but its main focus has recently shifted towards the statutory requirement to carry out Sustainability Appraisal (incorporating Strategic Environmental Assessment) as part of the new Local Development Frameworks.

Based on government guidance, SSAG assessed how it could work together, to pool resources and share learning. Several key areas of joint working were identified that could assist all the Suffolk authorities in producing Scoping Reports and carrying out later stages of SA and SEA. Using the draft guidance SSAG has worked to produce a core of information for all Suffolk authorities to use and adapt as they see fit. This includes a framework of objectives and indicators for Suffolk, a body of baseline data, and a document scoping relevant plans and documents from international down to county level. The SEA framework can be found in this document:

Sustainability Appraisal documents

This page will provide a central resource for accessing documents relating to SA and SEA in Suffolk. Those currently available to download are listed below, and further documents will be added as they are produced.

Context review

This document summarises key relevant plans and strategies which influence plan-making in Suffolk, and indicates any implications they present for SA or the plan-making process. This includes international, national, regional and county level documents. Much of this builds upon work carried out for the Regional Spatial Strategy for the East of England, RSS14 (marked RSS). Those marked Local will be completed by individual District and Borough authorities for their local area, if relevant.

This file lists all of the plans and programmes identified in the full scoping document above.

Baseline data collection

This template file contains baseline data for indicators in the SA framework for all Suffolk local authorities (County and District/Borough level where possible).

This updated version contains county level data for Suffolk as a whole.

All the documents related to SA and SEA for the minerals and waste development frameworks can be found in the Minerals and Waste Planning area.

Local Transport Plan 2006-2011 Strategic Environmental Assessment

The Environmental Report sets out the sustainability appraisal incorporating strategic environmental assessment for the Local Transport Plan 2006-2011.

Waste procurement programme Strategic Environmental Assessment

Background
The Suffolk Joint Municipal Waste Management Strategy was published in October 2003 and sets out the strategic framework for the management of municipal waste in Suffolk. This Strategy, which was subject to extensive consultation during its preparation, sets out how Suffolk's Local Authorities will work together, and in partnership with others, to minimise levels of waste generated and to manage waste in ways that are environmentally, economically and socially sustainable. The County Council remains committed to the Joint Municipal Waste Management Strategy and its aims to minimise the production of waste and to maximise recycling and composting.

In these aims Suffolk has been highly successful. Based on figures for 2005-6, Suffolk has the second-highest level of recycling/composting of all English counties (39.74%) and St Edmundsbury Borough Council is, with 50.6%, the top-performing district council in the country; the average national figure is just 23%. Improvements in recycling and composting will continue, and the Strategy aspires to reach recycling levels of 60% by 2010.

However, landfill costs are increasing, with the rate of landfill tax rising annually. In addition, 2009-10 will see the introduction of the Landfill Tax Allowance Trading Scheme (LATS), which could see Suffolk hit with very substantial fines if it landfills more waste than it has an “allowance” for. With the declining availability of landfill voidspace in the county being a further constraint, the Strategy recognises that it will not be possible to rely on landfill for the disposal of all Suffolk’s residual municipal waste in the future. The aim of the County Council’s waste procurement programme is therefore to explore a number of options for introducing non landfill facilities for the treatment of residual municipal waste (the waste stream remaining after the recyclable and compostable elements have been removed).

Preliminary work undertaken by the County Council has narrowed down the possible options for non landfill treatment of residual waste to the following two options:

  1. Mechanical biological treatment (MBT) with the production of refuse-derived fuel;
  2. Energy from waste (incineration with energy recovery).

In addition to each technology type being assessed, the relative merits of a single site solution or multiple location solution across Suffolk have also been considered.

Strategic Environmental Assessment
The first main stage of the waste procurement programme is to prepare an outline case, setting out the issues and highlighting the potential options for the treatment of residual waste in the medium- and long-term. This document, called the Strategic Outline Case (SOC), was presented to Suffolk County Council’s Cabinet in October 2006. Under EU legislation, it is necessary to prepare a Strategic Environmental Assessment of the waste procurement programme, and the final strategic environmental assessment report – the Environmental Statement – accompanied the SOC when the Cabinet considered the matter in October.

Strategic environmental assessment is a formal process to identify the environmental impacts of proposed options within a plan or programme, and then to make recommendations about mitigation measures that might reduce any possible negative impacts. A strategic environmental assessment has therefore been carried out on the proposals outlined in the waste procurement programme to assess and make recommendations as to which options are most environmentally favourable. The strategic environmental assessment also outlines the current state of Suffolk’s environment and environmental data is used to assess the options and alternatives of the waste procurement programme.
