EXPLANATORY NOTES
(These Explanatory Notes do not form part of the Permit)
1. BAT
It should be noted that Regulation 22 of the Regulations specifies that it is a Condition of a permit that the operator must use the best available techniques (BAT) for preventing or, where that is not practicable, reducing emissions from the installation. This is referred to as the ‘general’ BAT Condition.
This does not apply to the extent that any other Condition of the permit, or a standard rule which has effect as a standard rules Condition, has the same effect.
Examples of aspects of the operation that have not been regulated by specific Conditions are management and supervision systems, training and qualification and maintenance in general.
BAT is defined in Regulation 4 of the Regulations as follows:
"Best available techniques" means the most effective and advanced stage in the development of activities and their methods of operation which indicates the practical suitability of particular techniques for providing the basis for emission limit values and other permit Conditions designed to prevent and, where that is not practicable, to reduce emissions and the impact on the environment as a whole.
"available techniques" means those techniques which have been developed on a scale which allows implementation in the relevant industrial sector, under economically and technically viable Conditions, taking into consideration the cost and advantages, whether or not the techniques are used or produced inside the UK, as long as they are reasonably accessible to the operator.
"best" means in relation to techniques, the most effective in achieving a high general level of protection of the environment as a whole.
"techniques" includes both the technology used and the way in which the installation is designed, built, maintained, operated and decommissioned.
“BAT conclusions” means a document containing the parts of a BAT reference document laying down the conclusions on best available techniques, their description, information to assess their applicability, the emission levels associated with the best available techniques, associated monitoring, associated consumption levels and, where appropriate, relevant site remediation measures.
“emerging technique” means a novel technique for an industrial activity that, if commercially developed, could, when compared to existing best available techniques provide a higher level of protection of the environment, or at least the same level of protection of the environment and higher cost savings.
“emission levels associated with best available techniques” means the range of emission levels obtained under normal operating Conditions using a best available technique, or combination of best available techniques, as described
in BAT conclusions, expressed as an average over a given period of time, under specified reference Conditions.
Schedule 3 of the Regulations specifies the matters to be taken into account in determining BAT.
In considering BAT, SEPA would expect the operator to have regard to all relevant PPC sectoral or other technical guidance, including BAT Reference Documents published by the European Commission and UK technical guidance published by the Environment Agency.

7. PROPOSED CHANGE IN OPERATION OF INSTALLATION
It is a requirement of Regulation 45 of the Regulations that if you propose to make a change in the operation of the installation, you must notify SEPA at least 14 days before making the change. The requirement under Regulation 45 does not apply if you have already made an application to SEPA for the variation of the Conditions of the permit containing a description of the proposed change.
N.B. the requirements of Regulation 45 are in addition to any obligations you may have under the permit itself to only operate the Permitted Installation in the manner set out in the permit and to notify SEPA of proposed changes to the Permitted Installation.
Regulation 46 and Schedule 7 of the Regulations provide details on applications for variation of the permit in respect of proposed changes and substantial changes in operation.
“Change in operation” and “substantial change in operation” are defined in Regulation 2 of the Regulations.
8. ENFORCEMENT & OFFENCES
If SEPA is of the opinion that you have contravened, or are contravening or are likely to contravene a Condition of the permit, or an incident or accident significantly affecting the environment has occurred as a result of the operation of the installation it may serve an enforcement notice. Further details on enforcement notices are provided in Regulation 55 of the Regulations.
If SEPA is of the opinion that the operation of an installation poses an immediate danger to human health, threatens to create an immediate significant adverse effect upon the environment or involves a risk of serious pollution it must, in certain circumstances, serve a suspension notice on you. Further details on suspension notices are provided in Regulation 56 of the Regulations.
It is an offence to operate an installation covered by the Regulations without a Permit or in breach of the Conditions of the permit. It is an offence to fail to comply with the requirements of an enforcement or suspension notice. It is an offence to intentionally make a false entry in any record required to be kept under a Condition of a permit. Further details on offences and on penalties liable to be imposed upon conviction of an offence are provided in Regulation 67 of the Regulations.
Directors, managers and other individuals within a company may be held personally liable for offences under the Regulations.
All personnel who are responsible for fulfilling any Condition of the permit should be made aware of these facts.
9. BREACH OF A PERMIT CONDITION
Regulation 52 of the Regulations specifies that the operator of an installation must immediately give notice to SEPA of any breach of a Condition of the permit. It is an offence to fail, without reasonable excuse to comply with Regulation 52.
Any statement made by an operator to SEPA for the purposes of complying with regulation 52 may only be used in a prosecution for an offence where in giving evidence the operator makes a statement inconsistent with the initial notification.
All personnel who are responsible for fulfilling any Condition of the permit should be made aware of these facts.
10. RECORDED SYSTEMS, PROCEDURES OR INFORMATION RECORDING/ RETURN REQUIREMENTS
Where a Condition requires any system, procedure or information record/return, the operator may demonstrate compliance by making use of any relevant existing written system used for any other purpose and which meets the requirements of the relevant Condition.
11. SYSTEMATIC ASSESSMENT (AND REVIEW)
Where a Condition of the permit requires a “systematic assessment (and review)” the assessment should be undertaken in a methodical and arranged manner. If you require guidance on the scope or extent of any assessment (and review) required to be undertaken, you should contact your local SEPA office at the address or telephone number given above.
