2 About Blake Group Blake Group is one of the UK's largest and most established steel storage tank manufacturers and specialists in construction metalwork with a proven track record of quality installations in industrial, commercial and residential building projects. All our management team have practical experience and extensive knowledge in their specialist areas and the firm has organically-grown through reputation over the last 75 years. Blake Group is split into three distinct departments, Environmental Tanks, Fabrications and The Metal Centre. As leading spokespeople within the engineering & steel manufacturing industry, the firm spearheads industry delegations shaping policy at senior level and is a member of Oil Firing Technical Institute for the Petroleum Industry (OFTEC), the Energy Institute (formerly Institute of Petroleum) (EI), Association for Petroleum and Explosives Administration (APEA) and the British Standards Institute(BSi). As expert witnesses, the firm has acted as lead consultants to the Government, DEFRA, OFTEC and the British Standards Institute on oil storage regulations and works closely with both the Environment Agency (EA) and Scottish Environmental Protection Agency (SEPA) educating industries on Best Practice procedures in the storage of oil. Following the publication of the Control of Pollution Regulations (Oil Storage)(England) 2001, Blake Group successfully led an industry consortium consisting of major oil companies, the UK s automotive industry and leading generator firms to both the Department for Environment, Food & Rural Affairs (DEFRA) and the Environment Agency (EA) to review the implications of the Regulations and how it impacted on industry. Additionally, Blake Group played an integral part producing Water Industry Mechanical & Electrical Specifications (WIMES) a key water industry specification model. Representing the Energy institute (EI) MD Ronnie Blake sits on British Standards RHE13 Committee which in April 2010 reviewed BS799 Part5 - the standard for single skin and primary steel tanks.

7 Agriculture England & Wales

8 Official Guidelines

9 Guidelines Referring To Tank Design (Recommendations To Follow For Best Practice)

10 Guidelines Referring To Tank Design (Recommendations To Follow For Best Practice)...If a totally enclosed bunded tank is required/provided (typically of carbon steel construction), the bund shall comply with the relevant parts of Oil Firing Technical Association (OFTEC) Standard OFS T-200. [WIMES 3.06_Page 16] The Water Industry Mechanical and Electrical Specifications (WIMES) define the requirements for mechanical and electrical equipment used in the UK Water Industry. The specifications take the form of descriptive text coupled with data sheets. The WIMES documents have been produced with the co-operation and approval of the following Pump Centre member companies:

11 Tank Design Standards

12 Certifications To Ask For OFCERT (OFTEC Licence to Manufacture OFS T-200 Tanks ) OFCERT Steel Tank Plate (Affixed To Tank) BSi ISO: 9001 (Specifically For OFS T-200) ALWAYS REQUEST A COPY OF MANUFACTURERS OFCERT LICENCE PRIOR TO ORDERING TANKS

13 OFS T-100 Plastic Tanks (Generally for domestic use)

14 OFS T-100 Integrally-bunded plastic tank

15 OFS T-200 Steel Tanks (For industrial & commercial use)

16 OFS T-200 Integrally-bunded steel tank

17 How To Identify Non-Compliant Tanks

18 How To Identify Non-Compliant Tanks Most existing tanks are non-compliant some may be modified to comply, many will have to be replaced. Some tank defects are immediately obvious others may be harder to spot. Is the tank inside an open bund with properly sealed walls and base? If answer is NO, tank does not comply with Regulations. If the answer is YES the tank may still be non-compliant Is bund capacity at least 110% of tank capacity? Is bund internally sealed to be impermeable to oil and water? Are bund wall/base penetrations for fill/draw-off ONLY? Are all bund penetrations adequately sealed? Does vent pipe discharge vertically downwards into bund? If sight gauge fitted, is it inside bund and does it have an auto shut-off valve? If answer to any of above is NO, tank is non-compliant Is tank integrally bunded? (How can you tell?) Check for OFS T100 or 200 Certification as per PPG2 Guidelines

19 What to look for: Tank Filling Almost 95% of Pollution Incidents Result From Overfilling Following two points apply to all tanks: If tank vent can not be seen by person filling it, is it fitted with an overfill prevention device? Are all remote or low-level fill points fitted with drip trays? If NO to either of above, tank is non-compliant Overfill prevention devices should be considered even when tank can be seen & don t forget to check any waste oil tanks on site which are frequently remotely filled!

20 Case Study: Single Skin Tank With Open Bund Versus Bunded OFS T-200 Tank Design

21 Open Bund For Single Skin Tank Compared To OFTEC Certified Integrally-Bunded OFS T-200 Steel Tank OPEN BUND SECONDARY CONTAINMENT FOR SINGLE SKIN TANK CERTIFIED OFTEC OFS T200 INTEGRALLY-BUNDED TANK (TOTALLY ENCLOSED BUNDED UNIT - TEBU) OPEN BUND EXPOSED TO RAINWATER REQUIRING REMOVAL INTEGRALLY-BUNDED OFS T-200 TANK THIRD PARTY CERTIFIED PERMEABLE BUND WALLS REQUIRE EXPENSIVE LINING INTEGRALLY-BUNDED TANK IS RECOMMENDED DESIGN BY EA & SEPA COSTLY REGULAR SAMPLING OF BUND CONTENTS BY EXPERTS ALL RISK OF NON-COMPLIANCE WITH LAW REMOVED FREQUENT DOCUMENTING & REPORTING ON BUND CONTENTS REQUIRED REMOVES ALL COSTS FOR MAINTENANCE OF CONCRETE BUND COSTLY REMOVAL OF SPECIAL WASTE IF 0.1% OR MORE OIL FOUND NO REQUIREMENT FOR BUND CONTENTS SAMPLING CRACKS TO CONCRETE WALLS WOULD REQUIRE PATCHING UP NO REPORTING ON BUND CONTENTS COST OF LOSS OF CONTENTS IF SINGLE SKIN TANK LEAKS NO REQUIREMENT FOR COSTLY CIVILS WORK ON PLINTHS OR STANDS NO REQUIREMENT TO LINE CONCRETE WALLS OF BUND REMOVES RISK OF CONTAMINATION OF SPECIAL OR HAZARDOUS WASTE BUNDED TANK BECOMES MOBILE ASSET OF THE COMPANY CONTENTS IN SECONDARY TANK CAN BE FED BACK TO PRIMARY TANK - NO LOSS

22 Managing The Open Bund Operation Cycle Costly & Time Consuming COSTLY & TIME CONSUMING ONGOING INSPECTIONS & MAINTENANCE OF BUND REQUIRED NON-HAZARDOUS CONTENTS CAN BE DRAINED HAZARDOUS CONTENTS (0.1% OR MORE) REQUIRES EXPENSIVE SPECIALIST REMOVAL & DISPOSAL 4. REGULAR BUND MAINTENANCE 3. BUND CONTENTS REMOVAL 1. RAINFALL IS A MAJOR PROBLEM ALONG WITH CONTAMINATION FROM SPILLAGE, OVER FILLING OR LEAKING TANK 2. CONTENTS INSPECTION & ANALYSIS REPORTS OPEN BUNDS EXPOSED TO RAINWATER COLLECTION, SPILLAGE, OVER FILL AND OTHER CONTAMINANTS CONTENTS SHOULD BE REGULARLY CHECKED AND REMOVED REPORTS PRODUCED TO RECORD CONTENTS OF BUND ADDITIONAL ADMINISTRATION COSTS

23 Open Bund Considerations When building an open bund, consideration must be taken of rainwater which will reduce the capacity of the bund until it is removed. For example, if the bund is only designed to hold 110%, any rainwater gathering in the bund will reduce the capacity of the bund until the water is removed. The bund (until the water is removed) would therefore be non-compliant with Oil Storage Regulations as it would not then have the additional 10% of the primary tank capacity as required by Oil Storage Regulations. To remove the multitude of costly issues associated with open bunds, it is recommended to install an integrally-bunded tank.

24 The 0.1% Rule PPG2 Guidenote 0.1% Contamination In Bund = Special or Hazardous Waste

25 Best Case Solution Challenge: Client had non-compliant tanks following changes to the EA & SEPA Pollution Prevention Guidelines PPG2 (April 2010). Issues: Solution: 1. Inadequate walled bund 2. Walled area not lined 3. Less than 110% bund capacity 4. Single wall tanks 5. No inspection of walled area contents 6. No record of disposal of walled area contents 1. Certified OFS T200 Integrally-bunded tank and removal of front wall to brick bund to eradicate rainwater collection issues 2. Original wall to act as an impact barrier Picture: Original Single Skin Steel Bulk Tanks with Bund Picture: Replacement OFS T-200 Totally Enclosed Bunded Unit

26 Examples Of Non-Compliant Tanks

27 No Bund Lining Hazardous Waste Contents Polluting Local Area Reduced Bund Capacity Through Rainwater Collection Waste Pumped Straight To Drain No Analysis of Bund Contents More Than 0.1% Oil Contamination in Bund and Local Area

28 Non-Compliant Single Walled Tank Various Contents Reducing Bund Capacity Deliberate Hole In Bund Wall Polluting Immediate Grass Area Tank & Pipe Failure Causing Environmental Pollution Seepage Through Brick Walls Into Building

29 Bund Not Lined Properly Seepage Through Brick Walls Overfilling Caused Pollution

30 Rainwater, Spillage & Overfill Collection & Contamination Secondary Containment Rendered Useless By Rain Due To Reduced Capacity Ongoing Inspection, Analysis & Removal Of Contents Required
