<strong>the</strong> SEA. Each policy and its alternative(s) where applicable have been scored against this ‘Effect<br />

Classification’ <strong>for</strong> both SEA (Level 4) and SA (Level 3).<br />

3.29 The findings of <strong>the</strong> assessment <strong>for</strong> <strong>the</strong> proposed policy set <strong>for</strong> inclusion in <strong>the</strong> <strong>Local</strong> <strong>Plan</strong> is summarised<br />

against each of <strong>the</strong> environmental receptors and is presented within Section 4 to Section 16 of this SAR<br />

report.<br />

Impact and Effect<br />

Classification<br />

Explanation<br />

Significant<br />

Beneficial<br />

<br />

Where <strong>the</strong> potential opportunities <strong>for</strong> beneficial effects arising from implementation of<br />

policy measures has been determined to be significant, a judgement will be made on<br />

<strong>the</strong> basis that individual projects delivered under <strong>the</strong> policy measure would be<br />

responding to known and significant problems (e.g. shortage of af<strong>for</strong>dable housing).<br />

Beneficial<br />

<br />

Where <strong>the</strong> types of actions/reaction that might be pursued or expected under<br />

implementation of policy measures that are determined to have <strong>the</strong> potential to give<br />

rise to beneficial effects on an environmental receptor via a specified and identifiable<br />

pathway, but would not be addressing location specific issues where <strong>the</strong> effects have<br />

been classified as non-significant.<br />

Mixed<br />

/<br />

Where <strong>the</strong> types of actions/reaction that might be pursued or expected under<br />

implementation of policy measures that are determined could potentially give rise to<br />

both beneficial and adverse effects on an environmental receptor via a specified and<br />

identifiable pathway, but would not be addressing location specific issues where <strong>the</strong><br />

effects have been classified as non-significant.<br />

Neutral 0<br />

Where <strong>the</strong> types of actions that might be taken under a measure have been<br />

determined to be unlikely to give rise to risks of adverse impacts or opportunities <strong>for</strong><br />

beneficial effects on an environmental receptor via a specified pathway, or where<br />

insufficient in<strong>for</strong>mation has been provided about <strong>the</strong> measure to make a judgement as<br />

to <strong>the</strong> types of actions that its implementation might involve, a conclusion of ‘no<br />

impact or effect’ has been recorded.<br />

Uncertain ?<br />

Where <strong>the</strong> types of actions/reaction that might be pursued or expected under<br />

implementation of policy measures that can not at this stage be determined to have<br />

<strong>the</strong> potential to give rise to ei<strong>the</strong>r beneficial or adverse or any mix of <strong>the</strong> two on an<br />

environmental receptor via a specified and identifiable pathway.<br />

Adverse<br />

<br />

Where <strong>the</strong> types of actions/reactions that might be pursued or expect under<br />

implementation of policy measures that are determined to have <strong>the</strong> potential to give<br />

rise to adverse impacts on an environmental receptor via a specified pathway, but<br />

would not be likely to require ei<strong>the</strong>r and/or an Environmental Impact Assessment<br />

(EIA) or Appropriate Assessment (AA) at <strong>the</strong> project consent stage those impacts have<br />

been classified as non-significant.<br />

Significant<br />

Adverse<br />

<br />

Where <strong>the</strong> potential risk of an adverse impact arising from implementation of <strong>the</strong><br />

policy measure has been determined to be significant, a judgement will be made on<br />

<strong>the</strong> basis that an individual project delivered under <strong>the</strong> policy measure would be likely<br />

to require ei<strong>the</strong>r and/or an Environmental Impact Assessment (EIA) or Appropriate<br />

Assessment (AA) with respect to <strong>the</strong> environmental receptor or any feature of that<br />

receptor concerned as part of any subsequent project consent.<br />

Cumulative Effects Assessment (CEA) – incorporating consideration of Synergistic Effects<br />

3.30 The aim of <strong>the</strong> cumulative effects assessment (CEA) is to identify and assess <strong>the</strong> significance of<br />

combined impacts from multiple plans, policies and programmes (PPPs) that <strong>for</strong>m <strong>the</strong> component<br />

parts of <strong>the</strong> new <strong>Local</strong> <strong>Plan</strong> and o<strong>the</strong>r development / transport plans, e.g. <strong>the</strong> spatial/transport plans of<br />

neighbouring authorities. Individual impacts from a single plan or programme may not be significant on<br />

<strong>the</strong>ir own; however <strong>the</strong>y could become significant when combined with o<strong>the</strong>r impacts ( 26) .<br />
