Who do the regulations affect?

• Commercial, industrial, institutional premises
  storing any type of oil

• Containers gt 200 litres, above ground

• Tanks, Drums, IBCs, Mobile Bowsers

• England

8
Implementation time-scales

• Introduction was phased over several years to
  allow industry time to comply

• Originally High Risk sites were targeted

• As from 1st Sept 2005 all oil stores must comply

9
Principal Requirements

• Good tank design standards (including pipework)

• Secondary Containment - bund, or - drip
  tray (drums and mobile equipment)

10
Exemptions Waste mineral oil

• Any mineral based lube or industrial oil which is
  unfit for its intended use

• All other waste oils are covered by the
  regulations

11
Exemptions Underground storage

• Underground storage - controlled by Groundwater
  Regulations and Code of Practice

12
Exemptions Inside buildings

• Building should provide secondary containment

• Building Regulations - may require secondary
  containment for fire safety purposes

13
Exemptions Domestic oil storage

• lt 3500 Litres

• Wholly or mainly as a private dwelling

• exempt if container is less than 3500 litres

14
Building Regs Requirements

• New / replacement domestic tanks to comply with
  Approved Document J

• Secondary containment required if

• gt 2500 litres

• or close to watercourse or drain or loose
  fitting manhole cover

• or spilled oil could run over hard ground into
  watercourse

• or tank vent can not be seen during refilling

15
Exemptions Refining or onward distribution

• Oil refineries or storage for the onward
  distribution

• Institute of Petroleum - Environmental Guidelines
  for Petroleum Installations

• Good environmental practice expected at all sites

16
Exemptions Agricultural use of oil on farms

• Silage, Slurry Agricultural Fuel Oil
  Regulations 1991

• Secondary containment gt1500l

• Prior notice to the Agency

17
General Requirements Primary Container

• Container defined as fixed tank, drum, mobile
  bowser or Intermediate Bulk Container (IBC)

• Container must be fit for purpose sufficient
  strength

18
General RequirementsSecondary Containment
Capacity

• Tanks, mobile bowsers, IBCs - 110 total capacity
  if the container

• Drums - 25 of total

19
General RequirementsSecondary Containment

• Impermeable to oil and water

• No drain valves

• Pipes passing through wall must be adequately
  sealed

20
General RequirementsLocation

• Positioned or other steps taken to minimise risk
  of damage by impact

• other steps taken - collision barriers or
  bollards

21
General Requirements Ancillary Equipment

• Ancillary equipment (eg valves, filter, sight
  gauge, vent pipe) must be within the secondary
  containment

• Fill pipes should be inside the bund but where
  unavoidably outside a drip tray must be used

22
Fixed TanksSight Gauges

• Properly supported

• Auto close valve

23
Fixed Tanks Pipes, Valves Taps

• Vent pipes, taps and valves within bund

• Must be directed down into the bund

• All taps and valves - must be fitted with locks
  and locked shut when not in use

24
Fixed Tanks Pipework

• Protected from damage and corrosion

• Aboveground - properly supported

• Underground - regular testing

- leak detection - joints only allowed where
inspection facilities present
25
Fixed Tanks Flexible delivery hoses ...

• Tap/valve at delivery end with auto close

• Must not be capable of being left open unless has
  auto shutoff

26
Fixed Tanks Flexible delivery hoses

• Kept in secondary container when not in use

• Have lockable valve where pipe leaves container

27
Fixed Tanks Pumps

• Minimise damage by impact

• Check valve to prevent tank drain down

• Protect from unauthorised use

28
Fixed Tanks Delivery to the tank

• If tank and vent pipe can not be seen then an
  auto-overfill prevention device must be fitted

• Fixed couplings must be used if available (and in
  good condition)

29
Mobile Bowsers
30
Mobile BowsersAncillary Equipment

• Valves, filters, sight gauges, vent pipe and fill
  point within the secondary containment system

31
Mobile BowsersTaps and Valves

• Taps or valves through which oil can discharge to
  the open must have a lock and be locked shut when
  not in use

32
Mobile BowsersFlexible delivery pipes

• Be fitted with a manual pump or a valve at
  delivery end which closes automatically when not
  in use

• pump and valve locked shut

• be fitted with a lockable valve where it leaves
  the tank

33
Drum StorageDrip tray capacity

• Single drum minimum 25 of its capacity

• Multiple drums minimum 25 of total capacity
