Additional technical guidance for NYS bulk storage



- Some NYS bulk storage requirements are covered in previous

sections.



- This product contains flammable/combustible solvents.



- Materials of construction/compatibility

Material is commonly stored in closed stainless steel or

glass lined steel piping and storage tanks (at ambient

temperature). Any other materials such as reinforce fiber-

glass, plastic and etc. must be tested for compatibility be-

fore use. Consult supplier for materials for gaskets,

packing, etc.



- Condition for safe storage

Bulk storage design factors to consider are venting,

diking, separation distances between tanks and other

structures. Storage requirements should be determined

through consultation with qualified design and fire

protection engineers and fire insurance carriers.

Technical guidance may be found in pamphlet NFPA 30 or

factory mutual handbook of industrial loss prevention.

Recommended tank design: For pressure vessels, see American

Society of Mechanical Engineers (ASME) code, section VIII, 50

PSIG minimum pressure and full vacuum. For atmospheric tanks,

see API 2000 for design requirements.

Relief Valves: Flammable and Combustible Liquids code, NFPA

Nos. 30 and 29 CFR 1910.106, also consult API 520, 521. For



COPYRIGHT GENERAL ELECTRIC CO. page: 14
 piping design, consult ANSI B.31.3.



- Storage equipment

Corrosion protection, leak detection, spill and over-

fill protection requirements, installation and maintenance

information may be found in EPA final rule: 40 CFR part

280 underground storage tanks. New York State regulates

storage requirements of this material in 6NYCRR parts

595-599.



- Inspection and maintenance



NYS regulates some inspection and maintenance requirements

under 6NYCRR part 598.



API publication, guide for inspection of refinery

equipment, is a source for inspection and maintenance

information. (American Petroleum Institute, 1220 L. Street,

Northwest, Washington, D.C. 20005)



- Safety precautions, warnings and procedures for handling

and unloading bulk deliveries

Only qualified, fully trained and experienced persons

should sample, connect, load, unload, or disconect a tank

car, portable tank or tank truck.

When loading or unloading material in bulk, all DOT

(Department of Transportation) regulations found in 49 CF
172-178 must be followed when applicable. This will include

grounding, braking, attendance, etc.

The contents of the material to be unloaded should be

verified before any transfer is made.

Prior to unloading into a storage tank, a qualified

person must check the storage tank level to be sure that

the amount of material to be received will not overflow the

storage tank. The proper unloading connection should be

vented to a vapor removal, recovery or conservation system.
