                           Questions and Answers
SUPERFUND

Q: Has EPA established a preliminary
remediation goal for perchlorate in
groundwater?

A: Following the National Academy of
Sciences' National Research Council review,
EPA has adopted a reference dose (RfD) for
perchlorate of 0.0007 milligram/kilogram-
day (mg/kg-day) for the CERCLA
(Superfund) program.  This RfD leads to a
Drinking Water Equivalency Level (DWEL)
and preliminary remediation goal (PRG) of
24.5 micrograms/liter (ug/L) or 24.5 parts
per billion (ppb).

The National Contingency Plan (NCP) calls
for the development of preliminary
remediation goals (PRGs) based on readily
available information (40 CFR
§300.430(e)(2)(i)).  PRGs are generally
conservative, default endpoint
concentrations used in screening and initial
development of remedial alternatives before
consideration of information from a site-
specific risk assessment.  PRGs may be
modified as more information becomes
available through the site characterization
and remedial investigation process.

PRGs are often based on applicable or
relevant and appropriate requirements
(ARARs) under federal environmental, state
environmental, or facility siting laws.
Where no federal or state ARARs have been
promulgated (as with perchlorate), PRGs
may be developed based on "to be
considered" (TBC) values (§300.400(g)(3)).
The perchlorate RfD and corresponding
DWEL of 24.5 ppb are respectively the
recommended TBC value and PRG for
perchlorate.
RMP

Q: The endpoint concentrations for
regulated toxic substances under the risk
management program rule (40 CFR Part 68
Appendix A) are listed in units of milligrams
per liter (mg/L). Is this equivalent to parts
per million (ppm) ?

A: No, mg/L is not always equivalent to
ppm.  Whereas ppm is a volume-to-volume
or mass-to-mass ratio, mg/1 is a mass-to-
volume relationship. To convert from units
of mg/L to ppm, use the following equation.
 Endpointppm =
               Endpoint /L x 1,000 x 24.5
                   Molecular Weight
EPA has included the RMP toxic endpoints
in both ppm and mg/L in Appendix B of the
Risk Management Program Guidance for
Offsite Consequence Analysis (EPA550-B-
99-009, April, 1999).

OIL POLLUTION  PREVENTION

Q: If the owner or operator of a facility
subject to the SPCC regulations determines
that the installation of any of the specified
secondary containment structures or
equipment is not practicable and
accordingly provides in the facility's SPCC
Plan an oil spill contingency plan follow ing
the provisions of 40 CFR Part 109 pursuant
to §112.7(d), must the licensed Professional
Engineer (PE) who reviews and certifies the
SPCC Plan pursuant to §112.3(d) certify the
contingency plan? If the owner or operator
has submitted an FRP for the facility in
question, must the PE certify the FRP?

A: PE certification is required for any SPCC
Plan that may include a contingency plan
following 40 CFR Part 109 when secondary
containment is determined to be

-------
April 2006
                     Questions and Answers
impracticable. The determination of
impracticability involves good engineering
practice and compliance with alternative
measures in lieu of secondary containment.
Therefore, the contingency plan is
technically a material part of the SPCC Plan.
No PE certification is required for an FRP,
even when an impracticability determination
is made pursuant to §112.7(d).

Q: The SPCC rule requires inspections,
tests, and evaluations of aboveground
containers (40 CFR §112.8(c)(6)). Does the
rule set schedules for how often these need
to be conducted?

A: The SPCC rule does not prescribe a
specific frequency or methodology for
performing the required inspections,
evaluations, and tests for aboveground
containers. The SPCC rule is a
performance-based regulation that relies on
the use of good  engineering practices and
industry standards. These standards may
include testing procedures accepted by  the
American Petroleum Institute or the Steel
Tank Institute, among others. The certifying
Professional Engineer (PE) is responsible
for establishing  procedures for inspections
and testing at the facility and attests that the
Plan was prepared in accordance with good
engineering practices and consideration of
industry standards. The PE may also use
recommended practices, safety
considerations, and requirements  of other
federal, state, and local regulations.  As
described in 40  CFR §112.3(d), the PE must
attest that a facility's SPCC Plan is effective
to satisfy the requirements  of the  SPCC rule,
and this includes an appropriate inspection
program for aboveground containers.
TRI

Q: For Toxics Release Inventory (TRI)
reporting under EPCRA §313, is on-site
conversion of a metal compound to an
elemental metal or from the elemental form
of a metal to a compound of that same metal
considered treatment for destruction?

A: Generally, if the conversion of a listed
TRI toxic chemical into another substance
(listed or not) takes place in a wastestream,
it is considered treatment for destruction of
the initial chemical.  Metals, however,
generally are not considered as treated for
destuction because only the weight of the
parent metal is reported and the parent metal
cannot be destroyed.  Therefore, the
conversion of an elemental metal to a
compound of the same metal or from a metal
compound to the elemental form of the same
metal is not considered treatment for
destruction, even when such conversion
takes place in a wastestream. There are,
however, a few instances in which a TRI
metal or metal category compound may be
considered treated for destruction upon its
conversion to another form or substance
because the newly formed substance is not a
listed TRI chemical. For example, when
elemental barium or a barium compound is
converted to barium sulfate in a
wastestream, this is reported as treatment for
destruction because barium sulfate is not a
listed TRI chemical.  Similarly, aluminum
and zinc, which are only reportable in the
form of fumes or dusts, are considered
treated for destruction when they are
converted into non-reportable forms if this
conversion takes place in a wastestream.

Questions and Answers	April 2006

Q: How should quantities of toxic chemicals
released and managed as waste as a result
of non-production related events, such as
remedial actions or catastrophic events, be
reported on the EPCRA §313 Toxic
Chemical Release Reporting Form (Form
R)?

A: Quantities of a toxic chemical released to
the environment on site and quantities
transferred off site for disposal, treatment,
recycling, or energy recovery as a result of
remedial actions,  catastrophic events, or
other one-time events not associated with
production processes may be reported
distinctly in Section 8.8 (instead of Sections
8.1, 8.3, 8.5, or 8.7). In contrast, quantities
of a toxic chemical  combusted for energy
recovery, recycled,  or treated for destruction
on site must be reported in Sections  8.2, 8.4,
and 8.6, respectively - never in Section 8.8 -
even if they result from non-production
related, remedial, or catastrophic events.
