146 Introduction
STORAGE VESSELS FOR PE,TROLEUM LIQUIDS - SUBPART K
§60.ll0 - 60.113
The provisions of Subpart K of 40 CFR 60 dictate: ,perfor1T\anc'estandards
for storage vessels for petroleum liquids.
Subject to the requirements of
Subpart
K
are storage vessels with capacities greater than
151
m
3
(40,000 ,gal).
but not exceeding 246 m
3
(65,000 gal), which have commenced construction, re-
construction or modification after March 8, 1974.
In addition, those storage
vessels having a capacity greater than 246 m
3
(65,000 gal) and having commenced
construction, reconstruction or modif;ication after June 11, 1973, are subject
to Subpart K.
If the true vapor pressure of the petroleum liquid, as stored,
is equal to or greater than 10.3 kPa
(1.S
psia) but not greater than 76.5 kPa
(11.1 psia). the storage vessel must 'be equipped with a floating roof, a vapor
recovery system or their equivalents.
If the true vapor pressure is greater
than 76.5 kPa (11.1 psia) , the storage vessel must be equipped with a vapor
recovery system or its equtvalent.
The owner or operator of a storage vessel is required to maintain a file
of each type of petroleum liquid stored. Reid vapor pressure, dates of storage
and date on which the storage tank is emptied.
In addition, the owner or
operator shall record average monthly temperature and true vapor pressure.
No
performance testing is required for petroleum storage vessels.
Process Description
There are two types of petroleum storage tank emission reduction systems
presently being used:
floating roof and vapor recovery.
Floating roof storage tanks are used for storing volatile material with
vapor pressure in the lower explosive ranges minimizing fires or explosive
hazards.
There are 'three types of floating roof tanks:
pan, pontoon and
double deck.
The pan floating roof type has been used for the past 40 years
and
1.8
now being phased out.
Many operators have had tilting and sinking
problems with this type of roof; besides, the pan roof also has a high vapor-
ization loss around the periphery of the roof.
The pontoon roof is mainly
used on tanks with larger diameters and provides for better stability.
Some pontoon roofs have a center drain with hinged or flexible connections for
roof drainage problems.
In addition, traps or dams are provided on the under-
side of the roof.
The traps retain any vapors formed as a result of localized
Rolar boiltng.
The double deck floating roof, which is the most expensive,
reduces the effect of solar boiling and has more rigidity than the pan and
