SCHEDULE 1

Regulation 2(1)(a)

REQUIREMENTS FOR SILOS

1. The requirements which have to be satisfied in relation to a silo are that-

2. The base of the silo shall, where the silo has retaining walls made other than of earth, extend beyond those walls and shall in all cases be provided with channels so constructed as to collect any silage effluent which may escape from the silo and adequate provision shall be made for the drainage of that effluent from the channels to an effluent tank through a channel or pipe.

3. - (1) Subject to sub paragraph (2) below, the capacity of the effluent tank-

    (2) The effluent collection system associated with silos may, with the agreement of SEPA, incorporate a system of pumps and sumps, together with detailed sizing, pumping and management requirements, designed to reduce the capacity of the effluent tank.

     4. The base of the silo, the base and walls of its effluent tank and channels and the walls of any pipes shall be impermeable.

     5. The base and any walls of the silo, its effluent tank and channels and the walls of any pipes shall, so far as reasonably practicable, be resistant to attack by silage effluent and, where the walls are made of earth, they shall be lined with an impermeable membrane.

     6. No part of the silo, its effluent tank or channels or any associated pipes shall be situated within 10 metres of any inland or coastal waters which silage effluent could enter if it were to escape.

     7. If the silo has retaining walls-

8. Subject to paragraph 9, the silo, its effluent tank and channels and any pipes shall be designed and constructed so that with proper maintenance they are likely to satisfy the requirements of paragraphs 2 to 5 and, if applicable, 7(a) for a period of at least 20 years.

9. Where any part of an effluent tank is installed below ground level, it shall be designed and constructed in accordance with the Code of Practice referred to in paragraph 7(a) so that with proper maintenance it is likely to satisfy the requirements of paragraphs 4 and 5 for a period of at least 20 years.

SCHEDULE 2

Regulation 3(1)

REQUIREMENTS FOR SLURRY STORAGE SYSTEMS

     1. The requirements which have to be satisfied in relation to a slurry storage system are as follows.

     2. The base of the slurry storage tank, the base and walls of any effluent tank, channels and reception pit and the walls of any pipes shall be impermeable.

     3. The base and walls of the slurry storage tank, any effluent tank, channels and reception pit and the walls of any pipes shall be protected against corrosion in accordance with paragraph 7.2 of the Code of Practice on Buildings and Structures for Agriculture published by the British Standards Institution and numbered BS 5502: Part 50: 1993.

     5. - (1) Any facilities used for the temporary storage of slurry before it is transferred to a slurry storage tank shall have adequate capacity to store the maximum quantity of slurry which (disregarding any slurry which will be transferred directly into a slurry storage tank) is likely to be produced on the premises in any two day period, or such smaller capacity as SEPA may agree in writing is adequate to avoid any significant risk of pollution of inland or coastal waters.

    (2) Where slurry flows into a channel before discharging into a reception pit and the flow of slurry out of the channel is controlled by means of a sluice, the capacity of the reception pit shall be adequate to store the maximum quantity of slurry which can be released by opening the sluice.

     6. - (1) Subject to sub-paragraph (2) below, the slurry storage tank shall have adequate storage capacity for the likely quantities of slurry produced from time to time on the premises in question having regard to-

(2) Where it is proposed to dispose of the slurry on the premises by spreading it on the land, nothing in sub-paragraph (1) above shall require the tank to have a greater storage capacity than is adequate, having regard to the matters mentioned in sub-paragraph (3) below, to store the maximum quantity of slurry which is likely to be produced in any continuous six month period.

(3) The matters to which regard is to be had under sub-paragraphs (1) and (2) above are-

     7. No part of the slurry storage tank or any effluent tank, channels, pipes or reception pit shall be situated within 10 metres of any inland or coastal waters which slurry could enter if it were to escape.

     8. The slurry storage tank and any effluent tank, channels, pipes and reception pit shall be designed and constructed so that with proper maintenance they are likely to satisfy the requirements of paragraphs 2 to 4 for a period of at least 20 years.

     9. Where the walls of the slurry storage tank are not impermeable, the base of the tank shall extend beyond its walls and shall be provided with channels designed and constructed so as to collect any slurry which may escape from the tank and adequate provision shall be made for the drainage of the slurry from the channels to an effluent tank through a channel or pipe.

     10. - (1) Subject to sub-paragraph (2) below, where the slurry storage tank, any effluent tank or reception pit is fitted with a drainage pipe, there shall be two valves in series on the pipe and each valve shall be capable of stopping the flow of slurry through the pipe and shall be kept shut and locked in that position when not in use.

    (2) Sub-paragraph (1) above does not apply in relation to a slurry storage tank which drains through the pipe into another slurry storage tank of equal or greater capacity or where the tops of the tanks are at the same level.

     11. In the case of a slurry storage tank with walls which are made of earth, the tank shall not be filled to a level which allows less than 750 millimetres of freeboard, and in all other cases the tank shall not be filled to a level which allows less than 300 millimetres of freeboard.

SCHEDULE 3

Regulation 4(1)

REQUIREMENTS FOR FUEL OIL STORAGE AREAS

1. The requirements which have to be satisfied in relation to a fuel oil storage area are as follows.

2. The fuel oil storage area shall be surrounded by a bund capable of retaining within the area-

     3. The bund and the base of the storage area shall be impermeable and shall be designed and constructed so that with proper maintenance they are likely to remain so for a period of at least 20 years.

     4. Every part of any fuel storage tank shall be within the bund.

     5. Any tap or valve permanently fixed to the tank through which fuel oil can be discharged to the open shall also be within the bund, shall be so arranged as to discharge vertically downwards and shall be shut and locked in that position when not in use.

     6. Where fuel from the tank is discharged through a flexible pipe which is permanently attached to the tank-

7. No part of the fuel oil storage area or the bund enclosing it shall be situated within 10 metres of any inland or coastal waters which fuel oil could enter if it were to escape.

EXPLANATORY NOTE

(This note is not part of the Regulations)

These Regulations re-enact, with changes the Control of Pollution (Silage, Slurry and Agricultural Fuel Oil) (Scotland) Regulations 1991 ("the 1991 Regulations"), which require persons with custody or control of a crop being made into silage, of livestock slurry or of certain fuel oil to carry out works and take precautions and other steps for preventing pollution of inland or coastal waters.

The principal changes are-

(a) to clarify the meaning of the term "silage";

(b) to make provision to ensure that places where silage is proposed to be stored are at least 10 metres from inland or coastal waters;

(c) to allow persons making bulk bagged silage on farms to do so without restrictions where bags in which that silage is kept incorporate a facility which allows for the safe removal of excess effluent;

(d) to remove the 30 days notice provision in the 1991 Regulations where bulk bagged silage is made in an acceptable manner since that provision is now considered to be unnecessary;

(e) to allow for substantial reconstruction of an exempt structure with the agreement of SEPA, where the risk of pollution will be reduced;

(f) to extend the powers available to SEPA to serve notices in respect of all structures used for purposes covered by the 1991 Regulations rather than being restricted to exempt structures where there is a significant risk of pollution identified; and

(g) to allow SEPA in cases where a notice requiring works is necessary to require the drawing up and implementation of a Farm Waste Management Plan in accordance with methods identified for the collection, storage and land application of slurry and manure contained within guidance currently contained within the Code of Good Practice for the Prevention of Environmental Pollution From Agricultural Activity.
