TO:
Regional RCRA Senior Policy Advisors
As you know, the Administrator redelegated the delisting program to the Regional Administrators
on October 25, 1995. I understand that the redelegation has proceeded smoothly and am very pleased
with this result. You and your staff should be congratulated for this successful transition. Delisting was
and will continue to
be
an evolving program as substantive technical and policy issues continued to
develop. While working jointly with the Regions on a number of issues, we found it is important to have
and maintain an appropriate level of national consistency among the Regional delisting programs.
The purpose ofthis memorandum is to transmit to you a national policy for the hazardous waste
delisting program.
It
covers two important elements. First, the policy contains a "conditional delisting"
element, designed to ensure that delisted wastes are managed in a manner consistent with the risk
evaluation that supports the delisting decision. Second, the policy provides a delisting "reopener"
element, designed to provide the Agency with a mechanism for immediate response to new information
or data indicating conditions exist that may alter the Agency'sposition on the approval ofa delisting. I
recommend the
application ofeach ofthese elements ofthis national policy to ensure the EPA delisting
program remains safe and effective in protecting human health and the environment and at the same time
achieves the goal ofallowing the exit ofcertain wastes from the hazardous waste management system.
The principles ofthis policy have been discussed among the Regional delisting coordinators during a
series of monthly conference calls.
Background
In
considering whether to exclude a particular solid waste from the list of hazardous wastes
contained
in 40 CFR 261.31 and 261.32, the Agency has historically considered disposal in an unlined
landfill or surface impoundment to
be
representative ofthe reasonable worst-case
Electronic Filing - Received, Clerk's Office, June 30, 2008
management scenarios for such waste. The Agency believes that it is appropriate to consider the
worst-case management scenario because it is extremely difficult to project all potential management
scenarios that can occur once the waste is delisted. Thus, the Agency generally has only modeled the
risks related to these two disposal practices. The generic risk assessment model currently used (i.e.,
EPACML) or the model delisting may soon adopt (Le., EPACMfP) are designed only to predict
groundwater impacts for these two disposal scenarios (Le., an unlined landfill and an unlined surface
impoundment). These two models, as adapted to delisting, cannot predict risks resulted from exposures
to wastes that are managed in other non-disposal scenarios, including uses constituting disposal and
other recycling practices.
However, the Agency has generally not restricted how a delisted waste could subsequently
be
managed, provided it was managed in accordance with the applicable state'snonhazardous waste
management requirements. Therefore, generators could decide to manage their waste in another,
perhaps riskier, manner, and so the potential exposure from another and different naanagement practice
could pose greater environmental risks than the exposure scenarios modeled. For unconditionally
delisted wastes, there is typically no legal impediment to these changes in management.
Conditional Delisring Policy
To reduce the uncertainty caused by the potential unrestricted use or management to delisted
waste, it is important that new delistings apply only
to
wastes managed in the
type
of unit (e.g., "a
landfill") modeled in the delisting risk assessment. For example, ifthe delisting determination modeled
risks associated with disposal in landfills, the delisting would specify that the waste is delisted
conditioned on disposal solely in a landfill. Ifthe generator places the waste anywhere other than a
landfill, the waste is a "hazardous waste" subject to RCRA Subtitle C regulation, unless otherwise
exempted from regulation (Le., 40CFR 266.20). The regulations in 40 CFR 266.20, which apply to
recyclable materials (Le., hazardous waste) used in a manner constituting disposal, impose certain
requirements on such uses.
In
the Agency's view, a conditionally delisted waste would exit the hazardous waste management
system at the point it meets the established delisting levels, and would remain outside of the hazardous
waste management system so long as the delisted waste generator complies with the conditions placed
on the disposal ofthe delisted waste. The Regions should consider including.appropriate mechanisms in
conditional delistings that would help ensure that the waste was being managed in accordance with the
conditions. For
example, the Regions may consider adding a condition that the generator keep records,
such as those they keep for business purposes, as to where they sent the waste.
EPA's policy of not considering site-specific factors when applying the fate and transport models
remains unchanged. Therefore, at this time. Regions should not conditionally delist a waste based on
consideration of protective site-specific hydrogeologic conditions (e.g., underlying clay) or specific
landfill designs (e.g., liners, or covers). We would not be
2
Electronic Filing - Received, Clerk's Office, June 30, 2008
comfortable at this time delisting a waste based on consideration of site-specific hydrogeologic
conditions and specific landfill designs that would
not be delisted based on a less site-specific analysis.
While the Agency may consider a site-specific approach in the future, the Agency is not currently in a
position to commit the necessary time and resources such site specific modeling evaluations would
require and has not determined that this is an appropriate policy direction to take.
Nevertheless, the Agency realizes that for a relatively small number of petitioned wastes that are
not (or will not be) managed under a scenario our generic delisting models can assess, Regions may
have to consider site-specific circum!>tances or consider adding specific conditions, on a case-by-case
basis. These cases are likely to raise issues of national significance, therefore, the Region should consult
with the Office of Solid Waste.
Delisting Reopener Policy
In
light of a recent experience that required the Agency to repeal an existing delisting, we
recommend that the Regions include in future delistings, a provision that establishes a mechanism to
review the delisting when additional
data
become available indicating the initial delisting decision was
inappropriate or wrong. This is particularly important ifthe additional data shows that the delisted waste
is not behaving in the disposal site as was predicted by the delisting risk assessment model. Therefore,
Regions should include the following or similar language in future delisting decisions, unless there are
clear rationales not to:
(a)
If, anytime after disposal ofthe delisted waste, [insert facility name] possesses or is
otherwise made aware ofany environmental
data
(including but not limited to leachate
data or groundwater monitoring data) or any other data relevant to the delisted waste
indicating
that
any constituent identified in Condition (x)
is
at a level in the environment
(such as in the leachate or in the ground water) higher than the delisting level established
in Condition (x), then [insert facility name] must report such
data,
in writing, to the
Regional Administrator within
10
days of
first
possessing or being made aware ofthat
data.
(b)
Based on the information described in paragraph (a) and any other information received
from any source, the Regional Administrator will make a preliminaI)'determination as to
whether the reported information requires Agency action to protect human health or the
environment. Further action may include suspending, or revoking the exclusion, or other
appropriate response necessary
to protect human health and the environment.
(c)
Ifthe Regional Administrator determines that the reported information does require
Agency action, the Regional Administrator will notify the facility in writing ofthe actions
the Regional Administrator believes are necessary to protect human health and the
environment. The notice shall include a statement ofthe
3
Electronic Filing - Received, Clerk's Office, June 30, 2008
proposed action and a statement providing the facility with an opportunity to present
infonnation as to why the proposed Agency action
is not necessary or to suggest an
alternative action. The facility shall have 10 days from the date ofthe Regional
Administrator'snotice to present such infonnation.
(d)
Following the receipt
of infonnation from the facility described in paragraph (c) or (if no
infonnation is presented under paragraph (c» the initial receipt of infonnation described
in paragraph (a), the Regional Administrator will issue a final written detennination
describing the Agency actions that
are necessary to protect human health or the
environment. Any required action described in the Regional Administrator's
detennination
shall become effective immediately, unless the Regional Administrator
provides otherwise.
This language is intended to provide the Agency with a mechanism to review and act expeditiously
on infonnation that a previously
granted
delisting may be causing a
threat
to human health or the
environment that was unknown at
the
time the Agency acted initially. Use ofthis language will provide
you the ability to reopen, revoke, or otherwise suspend the delisting in a timely manner. Please share
this national policy with the states within your Region that axe authorized to administer their own
delisting programs
This memorandum provides guidance to EPA personnel. The guidance is designed to communicate
national policy regarding the RCRA delisting program. The memorandum does not, however, substitute
for EPA'sstatutes or regulations, nor is it a regulation itself. Thus, it cannot impose legally-binding
requirements on EPA, States, or the regulated community, and may not apply to a particular situation
based
upon the circumstances. EPA may change this guidance in the future, as appropriate.
Ifyou have any question regarding this policy, please feel free to contact David Bussard, Director,
Hazardous Waste Identification Division, at (703) 308-8887 or have your
staff
contact Rick Brandes,
Chief, Waste Identification Branch, at (703) 308-8890.

facilities. Shell generates hazardous and nonhazardous industrial solid wastes as a result of
refinery and chemical processes, wastewater treatment, refinery/chemical plant feed, product
storage and distribution.
Some
of the hazardous and nonhazardous solid wastes are disposed of in an onsite, permitted
hazardous waste landfill (MTR
Landfill- Site 104). Leachate from this landfill requires
offsite disposal as an F039 (multisource leachate) listed waste. However, analytical data
collected monthly for this aqueous stream shows that it is not a characteristic waste and
contains little to no detectable concentrations
oforganic constituents. Therefore, Shell is
interested in seeking a conditional exclusion for the landfill leachate
in accordance with
§40CFR260.20, §260.22 and "EPA Region 6
RCRA Delisting Program Guidance Manual for
the Petitioner."
2.5
STATEMENT OF INTEREST IN PROPOSED ACTION
Based on comprehensive chemical analyses performed on samples collected, this waste does
not exhibit the characteristics of a hazardous waste and does not meet the criteria for which it
was listed.
Once delisted Shell plans to treat the leachate
in the refinery'sNorth Effluent Treater (NET)
authorized under the National Pollutant Discharge Elimination Systems (NPEDS) program.
The leachate will be treated onsite and discharged rather than sent offsite for disposal at a
permitted commercial facility.
2.6
JUSTIFICATION FOR DELISTING
Shell has performed extensive testing of the petitioned waste stream by undertaking a
comprehensive sampling and analysis program.
EPA waS involved in developing the SAP
and approved its use on May 31,2002. Eight samples were collected
ofthe waste (four
primary and four secondary) and analyzed for a complete suite
ofparameters specified by the
SAP. The waste was not found to be characteristically hazardous. A copy
ofthe Quality
Assurance Report for this project is included as Appendix
A.
Using Region 6 Delisting Risk Assessment Software (DRAS), the analytical results also
show that the waste does not contain levels
ofhazardous or nonhazardous constituents that
would pose a significant risk to human health or the environment. The DRAS program
evaluated a scenario assuming that the leachate were treated
in a surface impoundment such
as the NET onsite.

WASTE AND WASTE MANAGEMENT HISTORY INFORMATION
3.1
DESCRIPTION OF PETITIONED WASTE
This plan covers a waste stream described as
MTR Landfill Leachate.
The F039 listing is for
a multisource leachate. The leachate is a dark colored liquid and is col1ected from the
primary and secondary leachate collection systems underlying the
MTR hazardous waste
landfill.
Figure 3-I provides a basic schematic of waste input and operation ofthe MTR Landfill.
The landfill occupies an area
of approximately 17 acres and is being constructed in three
stages, one cell at a time.
Cell 3 was constructed in 1990 and closed in 1995. Cell 2 was
constructed
in 1995 and is currently active and receiving primarily nonhazardous solid
wastes. Currently, there are
no plans to construct Cell 1. The entire landfill is scheduled for
closure
by 2007.
As shown, the landfill has both a primary and secondary liner with a leachate collection
system for both. The leachate is
pumped from the collection systems to two hazardous waste
storage tanks for the storage
«90-day) ofprimary leachate (tank T-323) and secondary
leachate (tank T-324). The leachate
has
been combined in tanker trucks.and disposed of as
F039 listed waste at
an offsite, permitted TSD facility.
The Texas Commission
on Environmental Quality (TCEQ) has recentiy granted Shel1
permission to discharge the leachate into the Houston Ship Channel
via NPDES permitted
outfall R-007. The TCEQ granted this pennission based
on Shel1's intention to have the
leachate delisted, and it will
be rescinded once the delisting process is complete.
3.2
HISTORY OF WASTE GENERATION
The MTR landfill began generating leachate around 1995 (Ce113); however, the volume has
increased substantial1y over the
past 3-5 years. The leachate is transported offsite for disposal
at an offsite permitted TSD facility
on a monthly basis. The volume ofleachate

PROCESS ANn WASTE MANAGEMENT HISTORY INFORMATION
4.1
GENERAL OPERATIONS AT THE GENERATING FACILITY
Table 4-1 provides a list of the raw products and refined products used and produced at this
refinery.
Shel1 Oil Company refines high sulfur crude oil from Mexico to products including
gasoline, kerosene,
jet fuel, fuel oil, lube oil and others. The facility occupies approximately
1600 acres in an industrial area on the south bank
ofthe Houston Ship Channel. The Shell
refinery portion
of the facility is located general1y north of the railroad tracks that cross the
facility in an east/west direction.
The refinery consists
of distil1ation, coking, cracking, refonning, hydrotreating and other
production units. The production units and their design
and production capacity are shown in
Table 4-2.
4.2
OVERVIEW OF CONTRIBUTING MANuFACTURING PROCESSES
There were very few hazardous wastes managed in the MTR landfill. The hazardous wastes
included incinerator ash, spent catalysts and filters, CPI sludge from the refmery wastewater
treatment plant (North Effluent Treater) andprlmary solids from Shel1 Chemical
and the
South Effluent Treater (SET). The wastes disposed
of in the MTR landfil1 for the past four
years have been Class I and Class 2 nonhazardous wastes
(Table 4-3). The fol1owing
sections describe the contributing processes that generate the predominant hazardous and
nonhazardous waste streams managed
in the MTR landfill.
4.2.1 Incinerator Operations (Generates Incinerator Ash)
Shel1 once operated an incinerator to destroy biosolids sludge from both the refinery and
chemical wastewater treatment plants. The waste
ash carried the listing D007, F002, F003,
F005, K048. Although there are no laboratory analyses available for the ash,
Table 4-4
shows the constituents that fonned the basis for listing
the EPA codes. It is unlikely that the
ash contained organic constituents, due to their destruction in the incinerator.

4.2.2 Maintenance Activities (for spent catalysts, fdters)
Many ofthe refinery processes use catalysts to facilitate the process and simplify the
hardware. Depending upon the process unit, spent catalyst are either hazardous or
nonhazardous. Hazardous spent catalyst is generally a listed waste from refining
hydrotreating processes. Nonhazardous spent catalyst generally is from the Catalytic
Cracking Unit (CCU).
Spent catalyst from the various hydrotreater units is generated during routine maintenance
shut-downs (tum-arounds). A turn-around usually occurs every two years at the.Shell Deer
Park Refinery. The hazardous spent catalyst is usually sent
off site for regeneration or
disposal.
Spent catalyst from the
CCU is generated as part ofthe process itself. New catalyst is
inserted into the
CCU on a daily basis with spent catalyst generated at the same rate. The
spent catalyst is accumulated in hoppers and is disposed
of every two weeks.
In
the past the
spent catalyst has been disposed
of in the MTR landfill. Currently, it is sent off site for
recycling. The spent catalyst generally contains elevated levels
ofnickel and vanadium.
Nonhazardous filter media is generated during the routine maintenance
ofthe various refinery
scrubbers. These filters are used to filter particulates from the various process and scrubber
streams throughout the refinery.
DEA polymer, bisphenol acetone (BPA) solids, and filter
media are all generated as part
ofthe amine regeneration and scrubbing process. Amine
solution
is circulated through various refinery scrubbers to remove hydrogen sulfide from the
process stream.
4.2.3 Refinery Wastewater Treatment Biosolids - Nonhazardous
As shown in Table 4-3, biological treatment sludge (biosolids) was disposed ofin the landfill
in 1999. Historical data for the sludge
shows that it was disposed ofin the landfill in
relatively large quantities in the past. The biosolids are generated at the North Effluent
Treater (NET) (unit number065 on the TCEQ Notice
of Registration). Figure 4-1 illustrates
the NET treatment process and points
of primary solids (CPI sludge) and biosolids
generation.
The process wastewaters treated
at the NET originate from refining and lubricant
manufacturing units. Waters treated include process wastewaters, ballast waters,
and water
recovered from the oil recovery system. Stormwater from the Stormwater Impoundment
Basin is also treated
in the NET.

Five CPI's are located within the Refinery and at the NET. These CPI'sprovide the primary
oil/water/solids separation step. Process waste, ballast water, and water recovered from the
oil recovery system are all treated
in the CPI's. The CPI discharge combines with stormwater .
from the Stonnwater Impoundment Basin prior to neutralization using caustic and sulfuric
acid.
The neutralized water flows through an equalization vessel. Discharge ofthe
equalization vessel is influent for the dissolved air flotation (OAF) unit (Intermediate
oil/water separation). The OAF effluent is further processed through the biological treatment
processes. These processes consist
ofa trickle filter and/or two activated sludge basins
(North Aeration Basin, South Aeration Basin). Effluent from the basins is clarified
in two
gravity bed clarifiers and deep bed, monomedia, gravity flow filters prior to discharge
through outfall R-007.
I
The biosolids collected off the clarifiers are processed through a thickener and digester to
reduce the water and hydrocarbon content. The sludge flows through the thickener (40-foot
diameter x 10
foot)with an average retention time of 13 hours.
It
is then digested in an
850,000-gallon aerobic digester for approximately 24 days. The dewatered sludge is then
either disposed
of in the MTR landfill, recycled in the refinery'scoker unit or sent off site for
disposal, depending
on the hydrocarbon content. TCLP analyses performed in the past show
that the sludge is not a characteristic hazardous waste once it has been processed through the
thickener and digester. Recent analyses
on the sludge show it is a Class 2 nonhazardous
waste.
4.2.4 Resin
Resins are no longer manufactured at the Shell Deer Park Refinery, as that business was sold
to a third party. Nonhazardous resin solids were generated at the Resins plant during the
cleanup
of various spills from either the resin solidification process and/or during the bagging
operations. The spilled resin was
picked up along with dust,
dirt
and other media during
cleanup ofthe process area. Resin solids also includes filter sludge, bag dust, pipe clean out
and vessel clean out
of solidified resiIl-
4.2.5 Shell Chemical Primary Solids
Chemical primary solids consist of sludge and solids that settle in the API separators in the
Shell Chemical Plant. Primary solids, consisting
ofmainly calcium carbonate, also collect in
the primary clarifiers
of the South Effluent Treater (SET) (unit number 017 on the NOR).
Figure 4-2 illustrates the SET wastewater treatment process. These solids may have residual
oil and resin, but are nonhazardous waste. The
SET treats wastewater from the chemical
units that produce oxygenated solvents, olefins, resins, vinyl chloride
monomer and phenol

acetone. Chemical analysis of the primary solids (6/23/00) show that the waste is not a
characteristic hazardous waste. Because the SET treats a listed wastewater from OxyVinyls
(KOI7, KOI9, K020), the solids generated from treatment
ofthe chemical wastewater might
be considered hazardous due to the derived-from rule. Shell is working with the TCEQ to
gain clarification on the regulatory status of these solids. OxyVinyls submitted a delisting
petition to EPA on October 11, 2002 to delist the wastewater for these waste codes.
4.2.6 Shell Chemical Biosolids
The biosolids are generated in the east, middle, and west aeration basins of the SET. They
consist
of biomass and floc that form the aerobic
di~estion
of the chemical wastewater. The
solids are separated in the three clarifiers that follow the aeration basins. Excess biosolidsare
processed through a thickener and filter press and transported
off site for disposal. In the
past, biosolids were disposed
of in the MTR. Chemical analysis of this waste stream in June
2000 showed that the waste is not hazardous due to characteristic and the Total Petroleum
Hydrocarbon content was less than 50 mglkg. The biosolids, like the primary solids, may
carry the KOI7, KOl9 and K020 listing until either OxyVinyls' wastewater is delisted or
regulatory status is determined.
4.2.7
Oil
Contaminated Media
Oil contaminated media includes Class I waste consisting of soil from spill cleanups and
from construction areas contaminated with oil.(TPH). This waste also includes rags, personal
protective equipment/clothing and spent absorbents/padslbooms contaminated with
nonhazardous oil.
4.3
LANDFILL OPERATION
AND
LEACHATE COLLECTION SYSTEM
The MTR landfill consists ofthree cells, a leachate collection system and two less-than-90
days leachate storage tanks. Cell 3 was constructed in November 1990 and capped in 1995.
Cell 2 was constructed in September 1995 and is open, and
Celli has not been constructed.
The landfill is currently scheduled for closure in 2007. Figure 4-3 shows a plan view
of the
landfill and the leachate collection and storage system.
4.3.1
Landml
Design
The landfill is designed to meet the minimum technological requirements (MTR) specified in
40CFR264.301. This includes design requirements ofa primary leachate collection system
and liner (underlying the deposited waste) followed

collection system and liner (underlying the primary liner). Figure
4-4
shows the components
ofthe primary and secondary leachate/liner systems.
4.3.2 Leachate Collection System Design
This landfill <;Iesign includes a series ofliners and leachate collection systems that envelope
the deposited waste to prevent migration
ofwastes and leachate out ofthe landfill. Just
beneath and in direct contact with the waste is the upper
or primary leachate collection
system. This system includes (beginning at the top) a three-inch sand layer, a layer
of
geotextile fabric, and a gravel layer whose thickness varies from 0.5 to 1.5 feet. Two eight-
inch perforated leachate collection pipes are located within the gravel layer
and are in tum
contained in two east-west trenches of each halfcell./
The eight-inch pipes connect on one end ofthe cell to a 12-inch perforated pipe which is
perpendicular
to the collection pipes and is contained in a two-foot deep sump at the outer
end of each half cell. Each end of the 12-inch headers is capped. Two 12-inch stand pipes,
also referred to
as well casings, connect to the sump pipe in each half cell. The stand pipes
are at right angles to the sump pipe and extend along the
IV:2H slope, following the inner
face
ofthe perimeter dike to the top of the landfill. Leachate filters through the sand layer
into the gravel layer. The high permeability gravel layer permits the rapid flow ofleachate
along a two percent slope in a north
or south direction, toward the two east-west oriented
trenches. The primary leachate collection system components slope from the center dike into
a lengthwise direction
in each half-cell toward the collection sumps.
The primary liner is immediately below the gravel layer. The primary liner is a single,
flexible membrane
of 100-mil high-density polyethylene (HPDE) material. This liner follows
the same contours and slopes as the primary leachate collection system sand and gravel
layers. The primary liner covers the
sides and the bottom ofthe landfill. The P1ll'P0se of this
liner is to contain all leachate so that
it can be collected and removed from the landfill.
If leachate penetrates the primary liner, it is collected in the secondary leachate collection
system. This system is located immediately below the primary liner and consists
of a 250-mil
HDPE drainage netting (see Figure 4-5). The length of the leak detection system is
interrupted at intervals
by 6 percent bentonite clay dams to divide the bottom area of the half
cell into compartments. In the trenches, each dam is penetrated by one to four leachate
collection/test pipes. Each
of the four pipes in a trench has a different length and is
perforated only at the end position that
IS between dams. This means that each pipe would

collect leachate from a single but different compartment. Utilizing this design enables the
identification
of the area of the primary liner where a leak is indicated. The HDPE drainage
mat is designed to allow the rapid flow
ofleachate to the collection pipes below.
Beneath the drainage mat and collection pipes
of the secondary leachate collection is the
secondary liner, which is an 80-mil HDPE flexible membrane and a 3-foot thick clay liner.
The HOPE liner, like the primary liner, completely covers the bottom
of the cell and extends
up the side walls
of the containment dikes, The flexible membrane liner is in direct contact
with and is supported
by a three-foot basal clay, low permeability liner
(1
x 10-
7
cm/sec
permeability). This compacted clay soil liner is designed to follow a two percent slope
toward the two east-west oriented trenches.
.
4.3.3 Leachate Collection Storage TankslTruck Loading
The storage facility consists oftwo I,OOO-barrel aboveground storage tanks; one for leachate
?ollected from the primary collection system (T-323) and one for the secondary collection
system (T-324). The tanks are supported
by steel structures placed on a concrete slab. The
slab is surrounded
by a 3-ft high concrete retaining wall providing secondary containment. A
tank truck-loading pad is constructed outside the secondary containment area. The storage
facility is equipped with piping, valves, and pumps to load leachate into tank trucks for
offsite disposal. The storage tanks are equipped with automated level sensors to detect spills
and overfills. The two tanks have valves that allow the trucks to load either from the primary
or secondary leachate tanks, or from both simultaneously. A sample port is located between
the pump and the loading pipeline to the truck.
4.4
DESCRIPTION OF WASTE MANAGEMENT UNITS
There are 7 hazardous waste treatment and storage units at the refinery. The hazardous waste
management units include one hazardous waste landfill
(MTR Landfill), three container or
dumpster storage areas, one wastewater treatment unit (NEn, one waste pile, and one pond
(North Pond). The locations
ofthese units (as identified by the NOR number) are shown in
Figure 4-6. Some of the units are exempt from permitting. The landfill is authorized under
the RCRA Permit No. HW-50099-001, issued
by the TCEQ and EPA. Table 4-5lists the
unit, its NOR number and the hazardous waste streams managed in each.
Hazardous wastes generated at the Shell refinery include CPI sludge, OAF solids, primary
solids and IGF float from the refinery wastewater treatment plant (i.e., North Effluent

PROCESS MATERIALS ANn WASTE VOLUMES
The primary raw product used in the refining process is a sour crude oil. Nickel and
vanadium-based catalysts are also used in the refining process.
The volume
of the waste streams sent to the MTR landfil1 from 1998 through 2001 was
shown previously
in Table 4-3. Oil contaminated media and chemical contaminated media
make up a large volume
ofwaste disposed ofin the landfill over the past four years. Spent
nonhazardous resin and catalyst also make up a large proportion
ofwaste consistently
disposed
ofin the landfill. Biosolids and chemical primary solids were sporadically
disposed
of in large quantities.
The volume
of leachate collected from the primary and secondary containment systems is
shown in
Table 4-7 for the past three years. The volume is measured in terms ofthe
combined volumes from Tanks T-323 and T-324. These data were taken from monthly
manifest logs and Shell'sAnnual Waste Summaries submitted to the TCEQ.
As shown the amount
of leachate generated and disposed of offsite has increased over the
past three years.
Shel1 is currently investigating the source of leakage into the primary and
secondary systems. To date the maximum monthly volume generated is approximately 1,277
tons and the annual maximum is 9,306 tons. To al10w for an approximate 50% increase in
volume, Shell is requesting to delist an annual maximum volume
of 14,000 tons.

5.1
CONSTITUENTS FORMING BASIS OF LISTING
Table 5-1 shows the list ofconstituents for the F039 multisource leachate for which the
waste was listed in 40 CFR 261, Appendix VII. The constituents are volatile organics,
semivolatile organics, metals, pesticides, herbicides, dioxins and furans. Appendix VII
of
261 refers to 40 CFR 268.43(a) for the list and states that the F039 listing includes "all
constituents for which treatment standards are specified for multisource leachate".
5.2
SELECTION
..
OF ANALYTE LIST
As part ofthe Sampling and Analysis Plan (SAP) for the petitioned waste stream, an analyte
list was developed. The components
of the list were based on process knowledge and
previous analytical data. The list was reviewed and approved (with modifications)
by EPA.
The analytes included
on a total basis are the Appendix IX list ofmetals, volatiles,
semivolatiles, pesticides, herbicides, PCBs and dioxins/furans. The Appendix IX
constituents are a refined list taken from the Appendix
VIIllist ofhazardous constituents.
The Appendix IX list includes the constituents for which the Shell waste was listed, the
constituents detected in the wastes, and
any other compounds that may exist as byproducts of
combustion (i.e., for the incinerator ash disposed of in the past).
Dioxins and furans may form as a byproduct from the incineration
of chlorinated aromatic
compounds such as chlorinated phenols, pesticides and PCBs (API, 1990, Dioxins
and
Furans - A Primer. Pub #4506). These compounds are included in the analytical program. A
2,3,7,8-TCDD
equivalent was calculated
f{)t~ach
set of dioxin/furan analyses using EPA
methodology.
The Appendix IX pesticides, herbicides
and PCBs were included in the analyte list as a
conservative measure. These compounds are
not used as raw products for contributing
processes and are not generated as a result
ofprocess operations. In accordance with Section
6.6.2
of the "EPA RCRA Delisting Program Guidance Manual for the Petitioner" the waste
streams samples were also analyzed for the following additional analyses:
•
Total oil and grease;
•
Total cyanide and sulfide;
•
Ignitability and
COITosivity

SAMPLING PERSONNEL INFORMATION
The landfill leachate was sampled by the following contractor:
Mr. Stephen Roach
On Site Hazardous Waste Coordinator
ONYX-Environmental Services
1800S. Highway 146
Baytown, Texas 77520
6.2
SAMPLING STRATEGY
Sampling was conducted in accordance with a written sampling plan (dated April 10, 2002)
and approved by the EPA in a letter dated May 31, 2002. Sample integrity was assured
by
following standard sample handling, preservation, documentation and custody procedures
(see Sections 6.4 through 6.7). A total
of eight samples and one duplicate were collected for
characterization:
6.3
SAMPLE COLLECTION AND IDENTIFICATION
Four samples of the primary leachate and four samples ofthe secondary leachate were
collected for characterization from June 2002 through October 2002. The sampling
procedures in the Sampling and Analysis plan were modified to incorporate
EPA'scomments
to sample and characterize
the primary and secondary leachate separately (site visit May 2,
2002). Procedures were followed and documented to show that each leachate collection tank
had a complete turnover between each sampling event.
Table C-I in Appendix C documents
the volume ofleachate removed from each tank prior to each sampling event. This procedure
ensured that four separate samples ofleachate were collected from each tank rather than
multiple samples from one
tank
volume ofleachate.
6.3.1
Initial Sample
The valve to
tank
T-323 (primary leachate) was opened by the operator and about I-liter of
leachate was purged and added back to the tank. The sample was then collected directly into
the sample bottles from the sample port. The sample for volatile analyses was collected first
by slowly filling two
40-mL VOA vials with little to no turbulence. There was no headspace
in the VOA vials when filled. The remaining bottles were then filled from the sample port.
For metals analysis, the sample was collected into three bottles containing no preservative.
005-01 rptdoc
Page 42
Electronic Filing - Received, Clerk's Office, June 30, 2008
Instructions were added to the chain-of-custody form for the laboratory to adjust the pH to 2,
7 and 9 upon receipt.
The date and time ofcollection was noted on each bottle and in the
field notebook. The sample J.D. was T323-1. This procedure was repeated with tank T-324
(secondary leachate) except the sample J.D. was T324-1
6.3.2 Second Sample
Prior to collecting a second sample from the leachate tanks, at least one tank volume (per
tank) was removed for disposal
off site. The volume of leachate removed from each tank was
documented. These log sheets are
with the laboratory analytical reports in Appendix C to this
petition. The samples were collected following the same procedures described above except
that only one bottle for metals was filled for each sample. The bottle for metals contained
preservative to adjust the sample
pH to less than 2.0.
I
The sample J.D.s were
T323-2 and T324-2.
The dates and times of sample collection were noted on the labels, field
notebook and volume log form.
6.3.3 Third Sample and Duplicate
The third sampling event was conducted following the above procedures. The sample J.D.s
. were T323-3 and T323-4. The date and time of collection was noted on the sample labels,
logbook and volume log form.
6.3.4 Fourth Sample
The fourth sampling event was conducted following the procedures inSection 6.3.2. A
duplicate sample was collected from tank T-324 for
QNQC
analysis. The fourth sample
J.D.s were T323-4,
T324-4A and T324-4B. The dates and times of sample collection were
noted
on the labels, field notebook and volume log form.
Resample Event
Due to anomalous readings for nickel in the fourth primary sample and methanol in the fourth
secondary sample, a resample event was conducted
on December 23, 2002. These samples
I.D.s were
Primary and Secondary. The dates and times of sample collection were noted on
the labels, field notebook and volume log form.
6.4
SAMPLE PRESERVATION AND HANDLING
All samples were placed in clean containers provided by the laboratory. Sample
preservatives were provided in the sample containers
by the analytical laboratory. Table 6-1
shows the containers, preservation,
and EPA holding times for the samples. Once the

SAMPLE CUSTODY
Chain-of-custody procedures were used to trace possession and handling of individual
samples from the time
of col1ection in the field through receipt by the independent analytical
laboratory.
Each time a batch
of samples was prepared for pickup by the laboratory, a chain-of-custody
record was completed and accompanied the shipment. Whenever custody
of the samples was
transferred, the individual relinquishing
and the individual receiving the samples signed,
dated, and noted the time
on the form. The original form accompanied the shipment to the
laboratory and was returned to the Project Manager with the analytical laboratory reports.

Ifa delivery or courier service was used to transportthe samples, the bill oflading or receipt
from the independent service was maintained
by the Project Manager to document custody
for that segment
ofthe sample transport.
6.7
QUALITY ASSURANCE/QUALITY CONTROL PROCEDURES
Each of the samples analyzed was subjected to extensive quality control. Quality control
procedures
in the field included sample handling and documentation protocols as described
previously. Techniques were used in the field to avoid sample contamination and to
adequately preserve each sample until it reached the laboratory. There was no sampling
equipment associated with. tank sampling, as samples were collected directly into the sample
containers. Decontamination
of equipment was not necessary (equipment rinsate samples
were not necessary).
Sampling personnel wore disposal nitrile gloves to reduce the possibility
ofcross
contamination. Sample bottles were laboratory-precleaned containers that
met cleaning QC
requirements.
Trip blanks, consisting oflaboratory grade deionized water were supplied by the laboratory.
These blanks were carried with the sample containers during the first
week and last week of
sample collection. The Trip Blanks were analyzed for Appendix IX VOA analyses. The
purpose
of the trip blanks was to determine the impact, if any, of ambient VOC
concentrations
in the refinery and laboratory during sampling and analysis.
Additional quality control procedures were employed in the laboratory.
As a minimum,
laboratory
QNQC
procedures were in accordance with the guidelines
in
Voluine One,
Chapter One
ofEPA document SW-846. Laboratory
QNQC
samples included method blank
analyses, surrogate spikes
and calibration curves. A discussion of the laboratory and field
QNQCdata is presented in the Quality Assurance Report
in
Appendix A to this Delisting
Petition.
6.8
STATEMENT OF REPRESENTATIVENESS OF SAMPLES
Based on the sampling strategy discussed in Section 6.2 (and in the SAP) and the use ofEPA
approved methods to collect, analyze
and maintain proper documentation and custody ofthe
samples, the samples
ofprimary and secondary landfill leachate collected in 2002 are
considered representative
of the petitioned waste stream. There were no deviations from the
SAP dated April
10, 2002 and revised May 15, 2002 during the June 2002-December 2002
sampling events (except the duplicate was collected from Round 4 instead
of Round 3).

petitioned waste stream from
June 2002 through December 2002. A copy ofthe laboratory
analytical reports are included as
Appendix
C.
005-0 Irptdoc
Page 47
Electronic Filing - Received, Clerk's Office, June 30, 2008
7.2.1 Hazardous Waste Characteristics
A summary ofthe results ofanalyses for reactivity, ignitability and corrosivity is included in
Table 7-1. As shown, none ofthe samples exhibit hazardous waste characteristics as defined
by 40 CFR 261.22 and 261.23. Table 7-2 and Table 7-3 compare the concentrations of the
TCLP constituents
in the primary and secondary leachate, respectively, to the maximum
TCLP levels found
in 40 CFR 261.24. As shown, none of the constituents in the primary or
secondary leachate exceed the maximum allowable TCLP concentrations and the landfill
leachate is not hazardous due
to the toxicity characteristic.
7.2.2
Appendix IX Analytes Detected on a Total Basis
Summaries ofthe constituents detected in the MTR Landfill Leachate, are presented in
Table 7-4 and Table 7-5 for the primary and secondary leachate, respectively. Only those
constituents detected above
the limit of quantitation (LOQ) are shown for the volatile and
semivolatile organics.
Volatile Organics
The volatile organic analyses were run on grab samples collected from the Primary Leachate
. Tank (T323) and from the Secondary Leachate Tank (T324). As shown very few volatiles
were detected.
Semivolatile Organics. PCBs. Pesticide. Herbicides, and Dioxin/Furans
Tables 7-4 and 7-5 present a summary ofthe semivolatile constituents, pesticides, herbicides,
PCBs and dioxin/furan results for
the primary and secondary leachate samples. For the
dioxin/furan results, EPA Region 6 recommends calculating a toxicity equivalent quotient
(TEQ) for 2,3,7,8-tetrachlorodibenzo(p)dioxin (TCDD).
The toxicity equivalent quotient is
calculated
by converting the 17 dioxin/furan congener concentrations to a 2,3,7,8-TCDD
concentration using toxicity equivent factors (TEFs). The TEFs for the 17 congeners are
listed in EPA Region 6 Delisting Technical Support Document (8/31102). The 2,3,7,8-TCDD
equivalent calculation spreadsheets are in Appendix E for the sampling events.
The
calculated 2,3,7,8-TCDD values are shown in Tables 7-4 and 7-5. These values are
compared to
EPA's delisting value for this constituent.
Metals
A summary ofthe Appendix IX metals detected in the samples over the sampling period is
shown in
Table 7-6 and Table 7-7 for the primary and secondary leachate, respectively.

During the first week of sampling, three samples were collected for pH adjustment to pH2,
pH 7 and pH9 prior to analysis for metals. This procedure was required by EPA to simulate
leachate from a landfill.
In accordance with the approved SAP this procedure was conducted
.on only one set of samples. A review ofthe data in Tables 7-6 and 7-7 show that the pH
variance did not appear to affect the concentration ofthe metals in the samples.

In accordance with EPA Region 6 requirements the analytical data for the samples were input
into the Delisting Risk Assessment Software (DRAS), Version 2.0 for evaluation. This
software program provides a scientifically defensible means to evaluate whether a RCRA
listed waste qualifies for delisting under 40 CFR §260.20 and 260.22 with regard to toxicity.
The program calculates carcinogenic and non-cancer risks associated with disposal
ofa
petitioned waste to a landfill or surface impoundment. For the Shell Oil evaluation, a surface
impoundment scenario was used since the
Landfill Leachate
will be treated in an
impoundment, once delisted. The methods used to calculate chemical concentrations in
, media at the point
of expos'nre are based on EPA'sfate and transport mechanisms. The
methods used
to determine risk associated with the waste disposal scenarios evaluated for
delisting a petitioned waste are based
on EPA'srisk assessment algorithms.
8.1
INPUT VALVES
In
accordance with the EPA RCRA Delisting Technical Support Document, the following
waste specific information was entered for the DRAS evaluation for both the primary and
secondary leachate:
•
waste volume: 14,000
tons/yr
=,16,619
cy/yr
(See Section 3.3)
•
waste management unit: surface impoundment
•
maximum concentration
ofvaAs detected (Table 7-4, primary and Table 7-5, ,
secondary)
•
maximum concentration of semivolatiles, pesticides, herbicides, PCBs, dioxins
detected (Table 7-4, primary and Table 7-5, secondary)
•
maximum concentration
of metals detected (Table 7-6, primary and Table 7-7,
secondary)
•
acceptable cancer risk
of 10-
5
•
acceptable hazard index of 0.1
•
multi-year delisting
(defuult of20 years)
The concentration data were entered as a "total" basis and TCLP basis since the waste
streams are aqueous. Per EPA Region 6 instructions, the detection limit was entered for
those constituents reported as below the detection limits. A separate DRAS run was
performed for the primary and secondary leachate. The output files from the DRAS runs are
presented in
Appendix F and discussed below.
