Compliance
Corner
In the United
States, hazardous wastes are subject to regulations mandated by
the Resource Conservation and Recovery Act (RCRA). Every month on
this page we provide clear, in-depth guidance on a different aspect
of the RCRA regulations. The information presented here is taken
from McCoy's RCRA Unraveled,
2010 Edition and is copyrighted by McCoy and Associates, Inc.
One thing you
will notice as you read the guidance presented below is references
to RCRA Online (RO) documents. These are letters, memos, or other
guidance documents issued by EPA and are often the source of the
information presented here. Each document is referred to with a
five-digit code (e.g., RO 11594). The most convenient way to obtain
copies of these documents is to use EPA's Internet-based document
retrieval service. This service, called RCRA
Online, is an excellent, free database developed by EPA. Go
to RCRA Online's Advanced Search Page. The second data-entry box
from the top on the right-hand side of the Advanced Search page
asks for the RCRA Online Number. Enter the five-digit RO code you
are interested in and click on the Search button. A "Search
Results" page will come up giving you a hyperlink and an abstract
of the document. Clicking on the hyperlink will retrieve the "Record
Detail" of the document, providing a summary and (finally)
a page icon hyperlink to the full text of the document.
Hazardous
Waste Tank Inspection Requirements
Subpart
J, specifically §§264/265.195, imposes a number
of inspection requirements on hazardous waste tanks at permitted
and interim status TSD facilities, as well as tanks at large
and small quantity generators. These requirements are summarized
in Table 1.
Subject
to certain restrictions, EPA will allow daily inspections
of tank and secondary containment systems as a way for owners/operators
to meet the release detection system requirements of §§264/265.193.
The release detection system standard is that the system
be able to detect a release within 24 hours of its occurrence.
Therefore, if such tank inspections also fulfill the release
detection system requirement, they must be conducted every
day that the system contains hazardous waste, regardless
of whether the facility is conducting manufacturing operations.
[RO 13063]
Addressing
another area of possible confusion, it is clear that the
bottom of tanks resting on concrete pads are technically
aboveground. However, EPA recognizes that they cannot be
visually inspected. Thus, the agency encourages facilities
to carefully look for leakage around the base of such tanks,
which could indicate releases from the tank bottom. [RO
12921]
Finally,
although EPA would probably frown on the use of a web
cam as a means to meet the tank system inspection
requirement, the agency in some cases would allow video
monitoring for such inspections. However, such a video system
must provide a level of performance comparable to
actual close-up visual inspection of the entire system and
the capability of effectively detecting leaks within 24
hours. [EPA/530/SW-87/012, RO 12868]
Owners/operators
of permitted and interim status TSD facilities and large
quantity generators must document that the above-noted inspections
were conducted. [§§264.195(h)/265.195(g)] Nothing
in the regulations requires small quantity generators to
record their obligatory inspections, but we would recommend
that such entities do that. Log entries for inspections
must include the following [§§264/265.15(d)]:
-
The
date and time of the inspection,
-
The
name of the inspector,
-
A
notation of any observations made (e.g., leaks, rusting),
and
-
The
nature of any repairs or other remedial actions initiated.
The
regulatory language requires the namenot the
initialsof the inspector to be documented. Inspections
should be recorded in the plant operating log and should
be kept for a minimum of three years.
Inspection
records are virtually certain to be scrutinized in a regulatory
inspection. Facility personnel can become bored with making
the same inspection day after day and sometimes want to
skip the inspection itself or filling out inspection logs.
Facilities need to give special attention to ensuring that
inspections are conducted and documented.
Examples
of items that should be considered for inclusion in a typical
tank inspection checklist or record include [OSWER Directive
9523.00-10]:
-
Appropriate
tank and piping labeling/marking;
-
Leaks
from tanks, pumps, and inlet/outlet nozzles or flanges;
-
Leaks
from or damage to ancillary equipment;
-
Seal
integrity on manholes, gauge hatches, weather shields,
and level gauges;
-
High
liquid level/overflow;
-
Structurally
intact with no damage to tank walls;
-
Evidence
of corrosion, excessive rusting, or damage;
-
Overfilling
controls operative;
-
Secondary
containment free of chips, cracks, etc.; and
-
Weekly
tank inspections allowed under certain conditions
Under
an April 4, 2006 final rule [71 FR 16862], large quantity
generators and TSD facilities are allowed to reduce the
inspection frequency of some components of their hazardous
waste tank systems (as noted in Table 1) from daily
to weekly when either of two conditions are met: 1) tank
owners/operators employ leak detection equipment per §§264/265.193(c)(3);
or 2) in the absence of leak detection equipment, tank
owners/operators employ established work practices that
ensure that when any leaks or spills occur, they will be
promptly identified and remediated per §§264/265.193(c)(3)
and (4).
EPA
gave the following examples of established work practices
that could be used to warrant weekly rather than daily tank
inspections of certain tank components [71 FR 16879]:
-
Use
of an environmental management system that includes plans
and practices to ensure that any releases are promptly
identified, contained, and cleaned up.
-
If
the tank system is in an area frequented by employees,
where releases will be immediately obvious, all employees
are trained to watch for releases and report them to appropriate
facility personnel.
-
An
employee is assigned to check the tank secondary containment
on a daily basis without conducting a full tank system
inspection.
The
tank regulations in §265.201 do not require small quantity
generators to have secondary containment for their 180-day
hazardous waste tanks. However, under the April 4, 2006
rule [71 FR 16862], small quantity generators are allowed
to reduce the inspection frequency of some components of
their hazardous waste tanks (as noted in Table 1) from
daily to weekly if they provide full secondary containment
for the tank or tank system and either use leak detection
equipment or implement established work practices to ensure
leaks are promptly identified.
If a
facility reduces its hazardous waste tank inspection schedule
to weekly for certain components, it must document the alternate
inspection schedule in its operating record. If the reduced
inspection frequency is based on established work practices
to ensure leaks are promptly identified, these practices
must be included in the documentation.
