What types of PCB Containers require
marking?
Containers with 50 ppm of PCBs, liquid or
non-liquid, must be marked (e.g., containers with
PCB remediation waste or PCB bulk product waste,
either of which has 50 ppm of PCBs).
What types of PCB Article Containers
require marking?
A PCB Article Container must be marked if it contains
a PCB Article, PCB Equipment, or PCB Container
that must be marked.
What are the marking requirements for
areas where PCB Articles are in use or
operating?
There are two types of locations where PCB Articles
in use or operating must be marked. One is the access
(e.g., machine room door, vault, highway,
fence) to where a PCB Transformer or a voltage regulator
with 3 lbs of 500 ppm of PCBs is located.
The other is a protected location for an individual
PCB Large (Low or High Voltage) Capacitor. A protected
location may be a pole, structure, or fence. In
such cases the individual capacitor does not require
marking but (1) the protected location must be
marked, (2) a record identifying the PCB Large Capacitors
must be kept at the protected location, and
(3) the individual capacitor(s) must be marked when
removed from the protected location.
If there is more than one door or access
leading to the location inside a building
of a PCB Transformer or voltage regulator
with>= 3 lbs. of <= 500 ppm of PCBs,
which door or access should be
marked?
All doors or accesses leading from the outermost
door to the door immediately accessing the PCB
Transformer or voltage regulator location should be
marked. Although the regulations do not require that
all these doors be marked, it is a best management
practice to do so. The reason is that marking all
doors from the outermost door leading to the innermost
door immediately accessing the PCB Transformer
or voltage regulator assists fire fighters in
identifying the location of the PCB Transformer or
voltage regulator.
What PCB storage locations are required
to be marked?
Only areas storing PCBs and PCB Items for disposal
are required to be marked.
Are there any other locations that
require marking?
There are two other locations, not mentioned in
40 CFR Part 761 Subpart C, that require marking.
First, is the marking of, or over, an encapsulated
area or at a barrier to a porous surface that was contaminated
with >=50 ppm of liquid PCBs and cleaned
up in accordance with 40 CFR Part 761.30(p). Second,
is the marking of fenced PCB remediation
waste sites cleaned up to > 25 ppm and <= 50 ppm of
PCBs in accordance with 40 CFR Part
761.61(a)(4)(I)(B).
