The material collected is preferably recovered and recycled or, if impossible, processed in accordance with point 5.5 and heading 7.
2.10. Retention bowls
Any storage of liquid products that may create pollution of water or soil is associated with a retention capacity that is at least equal to the largest of the following two values:
100% of the capacity of the largest tank;
50% of the overall capacity of the associated tanks.
Fixed tanks are equipped with level gauges and for buried storage of filling limiters. Storage under the soil level is permitted only in masonate or assimilated pit tanks. The watertightness of the tanks must be controlled.
When the storage is made exclusively of receptacles of unitary capacity less than or equal to 250 litres, allowed for transport, the minimum retention volume is equal to either the total capacity of the receptacles if that capacity is less than 800 litres, or 20% of the total capacity or 50% in the case of flammable liquids (except lubricants) with a minimum of 800 litres if that capacity exceeds 800 litres. The retention capacity must be watertight to the products it could contain and resist the physical and chemical action of the fluids. The same applies to the shut-off device that must be kept closed in normal conditions.
Containers or containers containing products that are likely to react dangerously together or contain products that are incompatible are not associated with the same retention bowl.
This provision does not apply to wastewater treatment basins.
The retention capacity is waterproof to the products it could contain and resist the physical and chemical action of the fluids. The same applies to its shut-off device which is kept closed.
The leakage of the (or) associated tank(s) may be controlled at any time.
Products recovered in the event of an accident may only be released under conditions consistent with this order or are disposed of as waste.

― the interior of buildings inhabited or occupied by third parties that have been implanted after the date of the declaration in the building areas defined above and their possible closest exterior parts (course, garden, terrace), excluding those of buildings located in areas intended to receive artisanal or industrial activities.
For existing facilities, reported no later than four months before the date of publication of this Order in the Official Gazette, the date of the declaration is replaced, in the above definition of regulated emerging areas, by the date of this Order.
The facility is constructed, equipped and operated in such a way that its operation cannot be caused by air or solidian noises that could compromise the health or safety of the neighbourhood or create a nuisance for the neighbourhood.
The sound emissions emitted by the facility are not at the origin, in the regulated emerging areas, of an emergence greater than the eligible values defined in the following table:
| greater than 35 and less than or equal to 45 dB(A) | 6 dB(A) | 4 dB(A) |
| Superior to 45 dB(A) | 5 dB(A) | 3 dB(A) |
8.2. Vehicles. ― Construction equipment
Transport vehicles, handling equipment and construction equipment used inside the facility are in accordance with the provisions in force for limiting their sound emissions.
The use of all acoustic communication devices (sirnas, tellers, loudspeakers, etc.), disturbing for the neighbourhood, is prohibited, unless their use is exceptional and reserved for the prevention and reporting of serious incidents or accidents.
8.3. Vibrations
The applicable technical rules are set out in Appendix II.
8.4. Operator monitoring of sound emissions
The operator puts in place a monitoring of the sound emissions of the facility to estimate the value of the emergence generated in the regulated emerging areas. The measurements shall be carried out according to the method set out in the annex to the decision of 23 January 1997. These measurements are carried out under representative conditions of the operation of the facility for at least half an hour.
A measure of noise level and emergence is carried out at least every three years by a qualified person or body.
9. Rehabilitation at the end of operation
In addition to the provisions set out in 1.7, the operator shall rehabilitate the site to ensure that there is no further danger and disadvantage. In particular:
– all hazardous products and all wastes are valued or evacuated to duly authorized facilities;
- tanks containing products that may pollute the water or cause a fire or explosion are poisoned, cleaned, degassed and, where applicable, decontaminated. They are if possible removed, otherwise they are neutralized by filling with a solid inert. The product used for neutralization covers the entire surface of the inner wall and has sufficient durability to prevent surface soil degradation.

TECHNICAL REGULATIONS
VIBRATION
The facility is built, equipped and operated so that its operation is not at the origin of vibrations in the surrounding constructions that could compromise the health or safety of the neighbourhood or create a nuisance for the neighbourhood.
The particulate velocity of the emitted vibration, measured by the method defined in this annex, shall not exceed the values defined below.
1. Limit values of particulate speed
1.1. Continuous or assimilated sources
Are considered continuous or assimilated sources:
- all machines emitting vibrations continuously;
― sources emitting pulses at fairly short intervals without limiting the number of emissions.
The limit values applicable to each of the three components of the vibration movement are as follows:
| Resistant constructions | 5 mm/s | 6 mm/s | 8 mm/s |
| Sensitive construction | 3 mm/s | 5 mm/s | 6 mm/s |
| Very sensitive constructions | 2 mm/s | 3 mm/s | 4 mm/s |
1.2. Repeated pulse sources
All sources emitting, in limited numbers, pulses at fairly short intervals but greater than 1 s and less than 500 ms are considered to be repeated pulses.
The limit values applicable to each of the three components of the vibration movement are as follows:
| Resistant constructions | 8 mm/s | 12 mm/s | 15 mm/s |
| Sensitive construction | 6 mm/s | 9 mm/s | 12 mm/s |
| Very sensitive constructions | 4 mm/s | 6 mm/s | 9 mm/s |
2. Construction classification
For the application of particulate speed limits, constructions are classified into three categories according to their level of resistance:
• Resistant constructions: constructions of classes 1 to 4 defined by Circular No. 23 of 23 July 1986 on mechanical vibrations emitted in the environment by installations classified for environmental protection;
• sensitive constructions: constructions of classes 5 to 8 defined by circular 23 of 23 July 1986;
- very sensitive constructions: constructions of classes 9 to 13 defined by circular 23 of 23 July 1986;
The following constructions are excluded from this classification:
- nuclear reactors and their associated installations;
- general safety facilities except for the constructions that contain them;
– dams, bridges;
• water castles;
- the long-range transport facilities of gases or liquids other than water, as well as the pressure water pipes greater than one metre;
– storage tanks for gas, liquid hydrocarbons or cereals;
- railway or road tunnels and other underground works of similar importance;
― harbour works such as dikes, docks and works located at sea, including drilling platforms for which the study of vibration effects must be entrusted to a qualified body. The choice of this body must be approved by inspection of classified facilities.
3. Method of measurement
3.1. Basic elements
The movement in one point of a construction is recorded in three rectangular directions, one vertical, the other two directions being defined in relation to the horizontal axes of the work studied without taking into account the azimut.
The sensors are placed on the main element of the construction (window support of a carrying wall, support point on the metal frame or concrete in the case of a modern construction).
3.2. Measuring apparatus
The measuring string to be used shall allow the recording, depending on time, of the particulate speed in the frequency band from 4 Hz to 150 Hz for the amplitudes of this speed between 0.1 mm/s and 50 mm/s. The chain dynamics shall be at least 54 dB.
3.3. Operational conditions
The sensors must be completely supportive of their support. Care must be taken not to install the sensors on the coatings (zinc, plaster, tile...) that can act as vibration filters or cause parasites vibration if these coatings are not well in solidarity with the main element of the construction. A measure of the existing agitations should be performed, if possible, outside the operation of the source.
