ENVIRONMENTAL PROTECTION AND NATURE CONSERVATION<br />

POLICY ENV2:<br />

NOISE AND VIBRATION<br />

1. <strong>Development</strong> that will either cause an<br />

unacceptable increase in noise or vibration<br />

levels or itself be subject to unacceptable<br />

noise or vibration from an existing source will<br />

not be permitted.<br />

2. Where developments are permitted, conditions<br />

may be attached to the planning permission to<br />

ensure effective noise insulation or other<br />

required mitigation measures are carried out.<br />

EXPLANATION ENV2<br />

13.15<br />

Noise problems can be created when proposals for<br />

noise generating development would be located near<br />

to existing noise sensitive uses such as housing,<br />

hospitals and schools. Areas that are considered<br />

tranquil (e.g. parts of the countryside or urban<br />

greenspace areas) should also be considered as<br />

noise sensitive and preserved for their amenity value.<br />

Conversely, problems can also be experienced where<br />

proposals for sensitive uses such as new housing<br />

would be located close to existing factories, roads or<br />

other existing sources of noise.<br />

PROCEDURES<br />

13.16<br />

Problems can be avoided by ensuring adequate<br />

separation distances between sensitive uses and<br />

sources of noise or vibration. Where a development<br />

would be likely to generate significant levels of noise,<br />

or be sensitive to an existing noise source, the<br />

<strong>Council</strong> will require that a noise assessment report<br />

be submitted as part of the planning application.<br />

The proposals will also need to incorporate any<br />

necessary measures to reduce noise or disturbance<br />

to acceptable levels. Noise control measures such as<br />

earth mounds or fencing should be designed so that<br />

they are as visually attractive as possible (including<br />

sensitive design and siting and an appropriate degree<br />

of landscaping). Further guidance on noise<br />

assessments can be found in <strong>Plan</strong>ning Policy<br />

Guidance Note 24 “<strong>Plan</strong>ning and Noise”.<br />

LIGHT POLLUTION<br />

1. <strong>Development</strong> requiring external lighting must<br />

satisfy the following criteria:<br />

a) The lighting scheme proposed is the<br />

minimum required for security and<br />

working purposes to undertake the task;<br />

b) There would be no unacceptable impact on<br />

visual amenity in the surrounding area;<br />

c) The scheme will not have an unacceptable<br />

effect on road safety;<br />

d) The scheme will not harm wildlife; and<br />

e) There will be no unacceptable loss of<br />

residential amenity.<br />

EXPLANATION ENV3<br />

13.17<br />

The lighting of developments is important for security<br />

and safety reasons. However, different forms of<br />

lighting, from street lighting to security lighting,<br />

increasingly and unnecessarily pollute today’s<br />

environment. Poorly designed or badly aimed lights<br />

that are responsible for “sky-glow” can have<br />

detrimental effects on wildlife, astronomical<br />

interests, highway safety and reduce the feeling of<br />

remoteness in rural areas. The <strong>Council</strong> may in some<br />

cases use conditions to require that lighting is<br />

orientated away from residential properties or from<br />

nearby amenity or countryside areas.<br />

13.18<br />

<strong>Plan</strong>ning applications for development should be<br />

accompanied by details of any lighting schemes<br />

proposed to allow assessment of any likely impact.<br />

POLICY ENV4:<br />

HAZARDOUS SUBSTANCES<br />

1. <strong>Development</strong> which involves the use or storage<br />

of hazardous substances, including<br />

modifications to existing establishments, will<br />

not be permitted if it would cause unacceptable<br />

risk to the users of the site, surrounding land<br />

users or the environment.<br />

2. <strong>Development</strong> within the consultation zones<br />

around existing hazardous installations or<br />

pipelines will only be permitted if:<br />

a) The level of risk to occupiers, visitors or<br />

users of the proposed development is<br />

considered acceptable; or<br />

b) The proposal includes measures that will<br />

mitigate the likely risks to the<br />

surrounding population.<br />

EXPLANATION ENV4<br />

13.19<br />

A fundamental aim of this policy is to prevent major<br />

accident hazards and limit the consequences of such<br />

hazards. Certain sites and pipelines are designated<br />

as hazardous installations by virtue of the quantities<br />

of hazardous substance present. The siting of such<br />

installations is subject to planning controls, for<br />

example under the <strong>Plan</strong>ning (Control of Major<br />

Accident Hazards) Regulations 1999. The objective in<br />

operating these controls is to maintain appropriate<br />

distances between establishments and residential<br />

areas, areas of public use and areas of particular<br />

sensitivity or interest. The <strong>Council</strong> will consult the<br />

Health and Safety Executive (HSE) about any<br />

proposals to site new hazardous installations, or to<br />

modify existing installations, within <strong>Knowsley</strong>.<br />

13.20<br />

The Borough of <strong>Knowsley</strong> already contains a number<br />

of hazardous substances establishments and major<br />

accident hazard pipelines. Whilst they are subject to<br />

stringent controls under existing health and safety<br />

legislation, it is considered prudent to control the<br />

kinds of development permitted in the vicinity of<br />

these installations. The HSE has advised the <strong>Council</strong><br />

on consultation distances for each of these<br />

installations. In determining whether or not to grant<br />

planning permission for a proposed development<br />

within these consultation distances the <strong>Council</strong> will<br />

consult the HSE about risks to the proposed<br />

development from the hazardous installation.<br />
