waste management facility license.
6.2 Petroleum Contaminated Soil
Processing Facility - Operating Standards
A. Field Sampling to Provide
Analytical Data for Evaluation of Candidate Soil
1. The contaminated soil must
be sampled and tested to adequately characterize it and to minimize
the potential of accepting hazardous materials or materials that the
soil processor is not permitted to accept. Details of field sampling
and test strategies are provided in § 6.5 of this Part.
B. Laboratory Tests of Field
Site Samples
1. Samples of contaminated
soil from field sites must be tested in a certified laboratory as
part of the soil verification procedures. Details of parameters to be
analyzed in the tests are provided in § 6.6 of this Part.

D. Sampling of Incoming Loads
at Processing Facility for Fingerprint Analysis
1. Appropriate sampling of
soil arriving at the facility shall be performed in order to
adequately fingerprint the soil and minimize the potential of
accepting hazardous waste. Details of fingerprint sampling are
provided in § 6.8 of this Part.
E. Transportation Practices
1. Measures shall be employed
to minimize precipitation run-on, prevent loss of soil or
contaminants from the truck, and prevent a spill of material, while
in transit. This applies to incoming soils and outgoing rejected
contaminated soil or processed soil. Recommended measures include:
a. A secured cover placed over
the soil.
b. A gate sealing method to
prevent leakage of any run-off of soil contaminant.
c. A chain wrapped around the
gate, as an additional securing feature to prevent the weight of the
load from forcing open the gate.
2. Additional measures may be
required by other states, when interstate transfers are involved, and
if the affected state(s) regulates this soil as a hazardous waste. It
shall be the responsibility of the soil processor to inform the
transporter, in advance, of the need to comply with these practices.
Failure of the transporter to follow these instructions shall be
grounds for load rejection by the processor.
F. Acceptable Uses of
Processed Soil
1. Any material processed by
RIDEM licensed solid waste management facilities, or by out-of-state
facilities and to be re-used within Rhode Island, may be used for any
of the following applications:

production.
b. Road base material
(provided covered by asphalt). Approval must be obtained from RIDEM
Office of Water Resources for each site or application where this
road base material is proposed to be used.
c. Landfill cover material in
any licensed RI landfill.
G. Limits of Parameters in the
Processed Soil
1. Any soil to be used as
aggregate for asphalt production within Rhode Island shall meet the
specifications of the appropriate party, e.g., RIDOT specifications,
when used on public state highways. Periodic testing of the aggregate
and/or asphalt shall be performed at the processing facility to
demonstrate that the material meets specifications.
2. Any soil to be used as a
landfill cover or road base material shall have TPH of 300 ppm or
less and shall meet any other specifications required by the given
landfill operator/owner or by the buyer of the road base material.
The landfill must amend its RIDEM operating plan to show it will be
accepting this material for landfill cover.
H. Sampling of Processed Soil
at Processor's Facility
1. Appropriate sampling and
testing of the processed soil shall be performed to determine the
extent of residual petroleum contaminant in the soil or due to other
requirements (if any) of the accepting party. Details of the sampling
and test strategy are provided in § 6.9 of this Part.
6.3 Petroleum Contaminated Soil
Processing Facility - Design Standards

equipment to ensure the most complete destruction of vaporized
hydrocarbons.
2. This may include
after-burner equipment or other equally efficient methods.
B. Design of Storage Chamber
for Incoming Contaminated Soil
1. An enclosed structure(s)
and a permanent roof to keep out adverse weather elements shall be
provided.
2. Soil shall rest on a
permanent, impervious floor, sloped to channel any run-off petroleum
products and water to a collection point or area.
3. Berming of the structure
(including any opening in the building for vehicle access) shall be
provided to prevent inflow of rainwater (run-on) and to prevent
run-off of petroleum contaminant/water from the storage piles onto
soil outside the enclosure
4. Adequate venting, such as
through use of roof vents, shall be provided to prevent build-up of
petroleum vapors.
5. Natural lighting, rather
than electric lighting or other types of artificial lighting, shall
be provided.
6. Electric power sources or
any other sources of heat or sparks shall be avoided. Electrical
devices, if any, shall meet the appropriate fire codes governing
prevention of sparks.
7. Soil storage, prior to
completion of the fingerprinting process, includes the following
options:
a. Storage in the enclosed
structure(s) with provisions to allow for, at minimum, all loads from
a given generator site to be segregated from loads from other sites
until fingerprint sampling and testing has been completed and the
loads have been accepted for processing
b. Storage in trucks at the
facility until the soil has been fingerprinted and has been accepted
for processing. The trucks shall be covered until the soil is
unloaded.
8. Sufficient storage capacity
shall be provided for soils to be stored per § 6.3(B)(7)(a) of this
Part, as well as for soils that have been accepted and are awaiting
transfer to the kiln for processing.
C. Design of Holding Area for
Processed Soil at Process Facility Site
1. Processed soil that has a
total petroleum hydrocarbon (TPH) concentration of less than 300 ppm
may be stored at the process facility site without any containing
enclosure or holding pad.
2. Processed soil that has a
total petroleum hydrocarbon (TPH) concentration of 300 ppm or greater
must be stored on an impervious holding pad, and adequately bermed to
prevent run-off from the pile from escaping to the surrounding soil.
3. Adequate erosion and
sedimentation control to minimize effect of any run-off from the
stored processed piles should be included.
6.4 Details of Waste Analysis
Plan (Per § 6.1(F)(2)(a) of this Part)
A. The waste analysis plan
must specify exactly what kind of materials the facility proposes to
accept for processing. The soil shall be contaminated with only
virgin petroleum products and associated spill clean-up debris.
Language like "such as" or "etc" used in
describing the incoming waste streams is unacceptable. In addition to
the types of accepted material, numerical limits must be proposed for
all significant contaminated soil parameters including, at a minimum,
flashpoint, total petroleum hydrocarbons (per any equipment
processing limitations), non-halogenated volatile organic compounds,
halogenated volatile organic compounds, EP toxic metals (arsenic,
barium, cadmium, chromium, lead, mercury, selenium, and silver),
polychlorinated biphenyls (PCB), cyanide, and Ph. The acceptable
physical state of the contaminated soil must also be specified. The
waste analysis section of the operating plan must also provide a
comprehensive waste verification procedure. This refers to efforts by
the waste processing facility personnel to ensure that the soil
received is contaminated by only virgin petroleum products and
associated spill clean-up debris and that the possibility of
accepting hazardous waste is minimized. Verification also allows the
processor to assess if the processing equipment employed for soil
clean-up will be adequate to handle the waste, given the levels of
contaminant and any required limits of contamination in the cleaned
product. Steps in the verification procedure include at least:
1. Pre-screening of the waste
through initial discussion between generator and waste processor.
2. On-site visit by waste
processor personnel to inspect the waste pile
3. Field sampling and
subsequent lab testing (see §§ 6.2(A), 6.2(B), 6.5, and 6.6 of this
Part for further details).
4. Documentation information
supplied by the generator in the contaminated materials profile sheet
and reviewed and accepted by the processor.
5. Fingerprinting (inspection,
sampling, and testing) of incoming waste, as it arrives at the
processing facility (see §§ 6.2(C), 6.2(D), 6.7, and 6.8 of this
Part for further details).
6. Other administrative forms,
to be completed by the generator, transporter, and processor, to
minimize the potential of accepting any waste other than that which
was originally tested.
B. Other key elements of the
waste analysis plan shall include sampling techniques and protocol,
identification of sampling personnel, identification of laboratories
that perform sample analyses, and the quality assurance/quality
control measures to ensure data integrity.
6.5 Field Sampling to Provide
Analytical Data for Evaluation of Candidate Soil (Per § 6.2(A) of
this Part)
A. The following represents a
minimal sampling and testing strategy. Additional sampling may be
required at a given site, on a case-by-case basis, to adequately
characterize the contaminated soil and to minimize the potential of
accepting hazardous materials or materials that the soil processor is
not permitted to accept.
1. Scenario 1: For projects
where contaminated soil has been excavated and stockpiled and where
the piles are "homogeneous" or "heterogeneous"
defined as follows:
a. Homogeneous Pile or Site -
A contaminated soil pile or site, where it is known or suspected that
only one type of spill material (contaminant) has occurred either in
a single spill or leak or multiple spills or leaks. Also, the pile or
site has an appearance of being approximately evenly contaminated
(approximately same concentration of contaminant throughout) based on
visual observation and/or using portable contaminant monitoring
devices.
b. Heterogeneous Pile or Site
- A contaminated pile or site, where it is known or suspected that
one or more spills of one type of spill material (contaminant) has
occurred in a defined area or sector of the pile or site, while one
or more spills of a second type of spill material has occurred in a
different, defined area or sector of the pile or site. Or
c. A contaminated pile or
site, where there are visual differences in the appearance of spill
material in different, defined areas or sectors of the pile or site
and/or where contaminant monitoring devices provide significantly
different readings in different, defined areas or sectors of the pile
or site such that:
(1) There is a potential that
different spill materials (contaminants) exist in separate, defined
areas of the pile or site or
(2) It is likely that the
concentration of contaminant of a single type varies significantly in
separate, defined areas of the pile or site.
d. Case 1 - Homogeneous Pile
or Site:
(1) Divide the overall pile
(on paper) into grid segments of 20 cubic yards each, when looked at
a three dimensional view. In each grid segment, collect one grab
sample at a depth of at least two feet. Collect it from the area of
the grid segment that appears to have the highest concentration of
contaminant, per visual observation. Alternately, if the
concentration of contaminant throughout the grid segment is uniform,
i.e., no discernible difference per visual observation, then collect
it from the mid-point of the grid segment.
(2) If the contaminated pile
is arranged such that the above grid segment plan and sampling
approach cannot be applied, then an alternate method can be used,
provided approval is obtained from the Solid Waste Section of the
RIDEM Office of Waste Management.
(3) In the laboratory, half of
each of the five grab samples from five adjacent grids will be
composited into one sample for test purposes and to represent that
cumulative 100 cubic yards of soil. (Therefore, there will be one
composite sample and one set of lab tests for each 100 cubic yard of
soil, or portion thereof). If any of the composite sample's test
indicate a problem (hazardous waste characteristics, material not
acceptable per the applicant's permit, etc.) then the soil processor
shall have several options:
(AA) Reject the entire pile at
the site or
(BB) Reject the entire 100
cubic yard of soil associated with each composite that has the
problem or
(CC) Re-test each individual
grab sample within the 100 cubic yard sector(s) that has the problem,
to determine if the problem can be isolated to a give grid segment
(and thus being able to accept other grid segments within that 100
cubic yard sector).
e. Case 2 - Heterogeneous Pile
or Site
(1) The procedures to be used
are the same as in Case 1 for homogeneous piles or sites, except for
the following:
(AA) Layout the grid network
in a manner that maximizes the number of adjacent grids that are
known or suspected to be homogeneous with one another.
(BB) In the laboratory,
compositing, for test purposes, will be performed on grab samples
from adjacent grids that are known or suspected to be homogeneous
with one another. Therefore, each composite will consist of a minimum
of one grab sample (from a grid that is known or suspected to be
heterogeneous relative to adjacent grids) to a maximum of five grab
samples (all known or suspected to be homogeneous with one another).
Thus, there will be one composite sample and one set of lab tests for
a maximum of each 100 cubic yards of soil.
2. Scenario 2: For projects
where excavation and stockpiling is not possible due to space
restrictions or environmental considerations:
a. After the boundaries of the
contaminated area have been established, divide the overall area (on
paper) into grid segments of 20 yd 3 each. Excavate in the
middle of the grid to the apparent limits of contamination. While
excavating, take grid samples at two foot vertical intervals and
composite these vertical samples into one sample.
b. In the laboratory, half of
each of the five composite samples from five adjacent grids will, in
turn, be composited into one sample for test purposes, and to be
representative of that cumulative 100 yd 3 of soil.
(Therefore, there will be one composite sample and one set of lab
tests for each 100 yd 3 of soil, or portion thereof). In
the event that any composite sample's tests indicate a problem
(hazardous waste characteristics, material that is not acceptable per
the applicant's permit, etc.) then the soil processor shall have
several options:
(1) Reject the entire amount
of contaminated material at the site or
(2) Reject the entire 100 yd 3
sector of soil associated with each composite that has the problem or
(3) Re-test each individual
composite sample from each grid segment within the sector(s) that has
the problem to determine if the problem can be isolated to a given
grid segment (and thus being able to accept other grid segments
within that 100 yd 3 sector(s)).
6.6 Laboratory Tests of Field Site
Samples (Per § 6.2(B) of this Part)
A. All sites, regardless of
spill material, will be required to have lab testing performed for
flashpoint, total petroleum hydrocarbons (TPH), and volatile organic
compounds (VOCs - including separate tests for halogenated and
non-halogenated VOC).
B. A full scan, to include at
minimum, the tests required in § 6.6(A) of this Part as well as
tests for EPTOX metals, PCB, cyanide, and pH will be required for any
of the following scenarios:
1. When the waste pile has
been moved from its original site of spill to an off-site location,
regardless of time elapsed since the spill occurrence or since the
time of transfer. (Logic - additional contaminated soil, containing
other types of contaminants, or contaminant alone could be combined
with this waste pile, off-site.)
2. When the soil processor's
representative cannot verify from on-site visual inspection and from
the statements or documentation of the generator, that the
contaminated pile contains only soil and contaminant and clean-up
debris from the excavated hole where the specific spill occurred.
(Logic - additional contaminated soil, containing other types of
contaminants from other locations at the generator's site or brought
in from other sites, could be combined with this waste pile.)
3. On sites with large volumes
of contaminated soil, the soil processor's license application shall
propose a volume, 'X' cubic yards or greater, that will require a
full scan. (Logic - potential for larger quantities of hazardous
waste in larger piles, which could result in significant
environmental releases during incineration. Therefore, need extra
caution (screen for hazardous waste using a full scan)). The
application should also provide some supporting statements and
justification for selection of this limit on volume of material.
C. As an option, the applicant
may choose up front to perform the full scan as defined in § 6.6(B)
of this Part, rather than proceeding through decision steps in §§
6.6(B)(1) through (3) of this Part in the above listed scenarios
D. If the applicant does not
select the option § 6.6(C) of this Part above and where § 6.6(B) of
this Part has been determined not to apply, then a sub-set of the
full scan tests shall be performed, when necessary, based on
knowledge of the contaminant (e.g., EP toxic lead for a spill of
leaded gas) and the following steps shall be taken to decide what lab
tests will be performed on field samples of contaminated soil:
1. Determination of the
constituents or elements in the virgin petroleum product at the time
of the spill, based on a recent fuel spec provided by the generator,
or laboratory testing of sample(s) of the virgin product, or some
other acceptable means to verify what is in the product. The
information provided shall include the concentration (mg/l or ppm) or
range of concentrations of each constituent or element.
2. Each constituent or element
that is at a concentration that is considered hazardous, according to
the "Rules and Regulations for Hazardous Waste Management",
when it becomes a waste product (when it is spilled into the soil),
shall be tested for, in the soil sample. Alternately, if the
information provided includes only a range of concentrations of each
constituent or element, then the highest concentration in this range
shall be considered to be actual concentration in the spill virgin
product. Examples include:
a. Selected EP toxic metals:
(1) Lead in leaded gasoline
and aviation fuels and cadmium in certain hydraulic oils
b. Carcinogenic properties:
(1) Benzene (known carcinogen)
in gasoline (restrict benzene to maximum of 1000 ppm in soil per
RIDEM regulations).
c. An exception is
PCB-contaminated soil. If the virgin petroleum product contains PCB
levels greater than 50 ppm (per recent fuel spec or by lab testing of
the fuel), then the resulting contaminated soil, regardless of the
measured concentration of PCB in the soil is hazardous waste (TSCA
regulations) and cannot be accepted for processing. Otherwise, if the
PCB concentration in the soil is greater than 1 ppm, then the soil
shall also be excluded from acceptance
E. If the applicant has any
doubt whatsoever that the soil may be contaminated by products other
than virgin petroleum products or may contain any constituent such
that the pile would be considered to be hazardous waste, then
additional testing such as a repeat of previous tests on other
portions of the pile or other types of tests, based on a suspected
contaminant, should be performed
6.7 Fingerprint Analysis and
Testing (Per § 6.2(C) of this Part)
A. Fingerprinting is performed
for numerous reasons, including:
1. As a safeguard against
outside undesirable or uncontrollable factors, specifically to allow
for an assessment of the material being received versus material
originally tested at the generator site, for conformity.
2. To allow the processor to
assess soil arriving at the facility to ensure it is processible,
given any limitations of the equipment employed for soil cleaning,
processing procedure limitations, and any required limits of
contamination in the cleaned material.
3. As a personnel safety
measure, relative to assessing material flammability, since the
material will be handled, stored, and processed.
4. As an environmental
regulatory measure, i.e., an additional safeguard to prevent the
acceptance of hazardous waste and to prevent material from being
processed, that is not within the processor's permit of material
acceptable for processing.
5. As a check on the analysis
and testing originally done on soil samples at the generator site.
6. As a tool to discourage
outside undesirable actions (prior to arrival at the facility) and to
encourage proper procedures in the waste acceptance multi-step
process.
B. Therefore, the minimum
fingerprinting requirements shall include:
1. Visual inspection of each
incoming truck load of soil, by the processor's
employee/representative as it arrives at the processing facility.
2. Appropriate sampling and
testing of the unprocessed soil (sampling and testing strategies are
presented in §§ 6.2(D) and 6.8 of this Part). The actual tests will
include, at minimum, soil flashpoint and a PCB test (whenever the
field sampling at the generator site included PCB testing and also at
the option of the processor). Other additional tests relative to
other parameters may be desirable for a more complete fingerprint, on
a case-by-case basis, per the suspected contaminant in the soil at
the generator site, as well as other factors. The processor should
indicate the normal testing protocol for these various cases. Also,
RIDEM may require additional tests, based on the conditions of the
processor's permit.
3. Wherever the term "full
scan lab tests" is mentioned in § 6.8 of this Part (which
discusses fingerprint sampling and testing strategies) this shall
include at minimum, flashpoint, total petroleum hydrocarbons (TPH),
volatile organic compounds (VOC) including separate tests for
halogenated and non-halogenated VOC, EPTOX metals, (arsenic, barium,
cadmium, chromium, lead, mercury, selenium, and silver) PCB, cyanide
and pH (see §§ 6.8(A)(4)(b), 6.8(A)(4)(c), 6.8(A)(5)(b) and
6.8(A)(5)(c) of this Part, where full scan lab tests apply).
4. The processor shall notify
all parties involved in the steps leading up to arrival of soil at
the processor's facility, including the generator, excavator, and
transporter that fingerprinting procedures will be employed (with
associated potential for rejection of soil).
6.8 Sampling of Incoming Loads at
Processing Facility, for Fingerprinting Analysis (Per § 6.2(D) of
this Part)
A. The following is a
guideline that represents a minimum sampling and testing strategy.
Additional sampling and testing may be desirable at a given facility,
on a case-by-case basis, to adequately fingerprint the soil and to
minimize potential of accepting hazardous waste. (Parameters to be
analyzed in the tests are discussed in §§ 6.2(C) and 6.7 of this
Part.)
1. Each truck load of waste
arriving at the facility shall be sampled. This applies to all loads
from a given field site (generator site) originating from a small or
large excavated pile or unexcavated area and even if the material
appears to be homogeneous at the site.
2. Sampling may be performed
while the load is on the truck or after the load has been deposited
in the receiving area (in the latter case, the load shall be
segregated from other truck loads from the given field site, at least
until sampling is completed).
3. At least five grab samples
shall be collected from each truck load, from a depth of at least one
foot, at zones within the pile designated as north, south, east,
west, and center. In each zone the sample should be collected from
the point with highest visually observed contamination concentration
level. These samples shall be composited into one sample.
4. If the processor's facility
design and operating procedures are such that all truck loads from a
given site are combined into one overall pile, after sampling for
fingerprint analysis, then the following applies:
a. Composite samples from
approximately five truck loads will, in turn be composited into one
overall sample, representing approximately 100 cubic yards of soil
and for test purposes (therefore, there will be one overall composite
sample and one set of fingerprint tests for each 100 cubic yards of
soil, or portion thereof).
b. Fingerprint tests should be
performed on a portion of each overall composite sample, with the
results compared to the lab test results on generator site samples.
If there is significant comparison differences for any of the
composite samples, then the fingerprint tests should be repeated on
the remaining portion of each composite sample, where results
differed. A "significant comparison difference" shall mean,
considerably lower flashpoints or considerably higher PCB levels in
the fingerprint samples (per discretion of processor) and definitely
any samples indicating flashpoints less than 100ºF or PCB levels
greater than 50 ppm. If any of the repeat fingerprint tests verifies
significant comparison difference for any of the composite samples,
then the processor has options as follows:
(1) Reject all truck loads
from that generator site or
(2) Perform a full scan of lab
tests on each composite sample with significant comparison
differences per above. If any of these full scan lab tests indicate
the presence of hazardous waste or the presence of a material the
processor is not permitted to accept, then the processor shall reject
all truck loads from that site
c. For any site requiring 'X'
or more truck loads or 'X' cubic yards (or more) of waste to be
processed, whichever is smaller, there shall be at least one full
scan lab test performed on one of the composited samples from five
truck loads, per above. If test results indicate the presence of
hazardous waste or the presence of a material the processor is not
permitted to accept, then the processor shall reject all truck loads
from that site. (The processor shall propose appropriate criteria for
this test to be triggered, i.e., define 'X' in the limits above and
discuss reasons for selection of these limits.)
5. If the processor's facility
design and operating procedures are such that segregation of
portion(s) of a generator's soil is maintained, after sampling for
fingerprint analysis and until fingerprint tests on that soil are
completed, then the following options apply:
a. The processor may use the
procedures exactly as described in §§ 6.8(A)(4)(a) through (b) of
this Part above or
b. The processor may use a
modified version of in §§ 6.8(A)(4)(a) through (b) of this Part as
follows:
(1) Composite samples from
approximately five truck loads or from all truck loads in a given
segregated holding area, (but from no more than 100 yd 3 of
soil), shall be composited into one overall composite sample for test
purposes. (Therefore, there will be one overall composite sample and
one set of fingerprint tests for a maximum of each 100 yd 3
of soil.)
(2) Fingerprint tests shall be
performed on a portion of each overall composite sample, with the
results compared to the lab test results on generator site samples.
If there is significant comparison differences for any of the
composite samples, then the fingerprint tests shall be repeated on
the remaining portion of each composite sample, where results
differed. If any of the repeat fingerprint tests verifies significant
comparison differences for any of the composite samples, then the
processor has options as follows:
(AA) Reject all truck loads
from that generator site or
(BB) Reject all truck loads
from the segregated holding area(s) associated with each of the
composite samples that tested significantly different.
(CC) Perform a full scan of
lab tests on each composite sample with significant comparison
differences per above. If any of these full scan lab tests indicate
the presence of hazardous waste or the presence of a material the
processor is not permitted to accept, then the processor has the
option of rejecting all truck loads from that site, or at minimum,
rejecting all truck loads from the segregated holding area(s)
associated with each composite sample that test positively for
hazardous waste characteristics or unacceptable material, per above.
c. For any site requiring 'X'
or more truck loads or 'X' cubic yards (or more) of waste to be
processed, whichever is smaller, there shall be at least one full
scan lab test performed on one of the composited samples from five
truck loads, per above. If test results indicate the presence of
hazardous waste or presence of a material the processor is not
permitted to accept, then the processor shall have the option of
rejecting all truck loads from that site, or at minimum, rejecting
all truck loads from the segregated holding area(s) associated with
that composite sample and performing additional full scan lab tests
on the other composite samples. (The processor shall propose
appropriate criteria for this test to be triggered, i.e., define 'X'
in the limits above and discuss revisions for selection of these
limits.)
6.9 Sampling of Processed Soil at
Processor's Facility (Per § 6.2(H) of this Part)
A. The following is a
guideline that represents a minimum sampling and testing strategy.
Additional sampling and testing may be desirable at a given facility,
on a case-by-case, or where required by the party that will be
accepting the soil for re-use. Details of the actual tests and
analyses will be based on any requirements of the accepting party.
1. Each 100 cubic yards of
processed soil shall be sampled and tested. From each 100 cubic yards
of processed soil in the holding area take five grab samples, each
from a depth of at least one foot in the pile. The locations of the
sample points shall be from designated zones within each 100 cubic
yards grid, i.e., north, south, east, west, and center. The grab
sample will, in turn, be composited into one sample for test purposes
and a portion of this sample will be tested in the laboratory. If the
test results indicate that the soil is sufficiently void of
contaminants, then it can be moved out of the holding area and stored
in other areas of the process facility.
