CHAPTER 5
SUMMARY WORKSHEETS
This chapter contains the summary worksheets on which closure and post-
closure costs for each technology can be added together to produce closure and
post-closure cost estimates for the TSDF. These worksheets also include provi-
sion for reflecting regional cost differences, uodating costs to current
dollars, and including appropriate fees. The summary worksheets in this section
are identical to those in Volume I!, so if the user plans to use the summary
worksheets in Volume II, these summary worksneets do not need tc be used. The
summary worksheets are as follows:

CHAPTER 1
INTRODUCTION
Subpart H of Part 264 and Part 265 of the RCRA Subtitle C regulations
requires that owners/operators of all hazardous waste treatment, storage, and
disposal facilities (TSDFs) prepare an estimate of the cost for closing the
facility in accordance with the RCRA regulations. In addition to the closure
cost estimates, TSDF owners/operators are to prepare estimates of the cost of
post-closure care for those facilities at which wastes will remain after clo-
sure. Financial assurance must be established for closure and post-closure, the
amount of which is based on these cost estimates. Reviewers of closure and
post-closure cost estimates need to be able to determine whether the cost esti-
mates are reasonable in order to assess the adequacy of the closure and post-
closure financial assurance. This involves consideration both of the closure
and post-closure plans and of the unit costs and calculations used to develop
the cost estimates.
This is Volume II of the Guidance Manual: Cost Estimates for Closure and
Post-Closure Plans (Subparts G and H). The purpose of this volume is to provide
a framework for developing the closure and post-closure cost estimates for land
disposal technologies. It is intended for use both by TSDF owners/operators who
prepare closure and post-closure cost estimates and by state and EPA Regional
personnel who are responsible for reviewing the cost estimates. This volume
contains the worksheets for estimating closure and post-closure costs (including
contingent cost estimates) for waste piles, surface imooundments, land treat-
ment, and landfills. In addition, it includes summary worksheets for totalling
the facility costs.
Following this introduction, Volume II is divided into six major chapters.
The first four contain closure cost estimating worksheets for waste piles, sur-
face impoundments, land treatment facilities, and landfills, respectively. The
1-1
-------
OSWER Policy Directive
#9476.00-6
fifth chapter contains worksheets for estimating post-closure costs. The final
chapter of this volume contains the summary worksheets; it is identical to the
summary chapter in Volume I - Treatment and Storage Facilities.
Within each chapter, the worksheet:; are grouped by letter to indicate tech-
nology and by number to indicate individual worksheets. For example, the
Inventory Management worksheet for waste piles is Worksheet D-l; the Final Cover
worksheet for landfills is Worksheet G-6. All worksheets can be used for esti-
mating both Part 264 and Part 265 costs except those for groundwater monitoring.
There are separate Part 264 and Part 265 worksheets for this activity because
the regulations differ.
The worksheet blanks to be filled in are arranged in two columns. All
facility data, unit costs, and intermediate calculations are placed in the left
column. Results of all subtotal calculations are placed in the right column.
The final line item in each worksheet is a subtotal that is entered in a box.
This is the sum of all costs in the right column.
For the user's assistance, typical unit costs and a page number reference
are provided in parenthesis to the left: of the worksheet blanks. In some cases,
a typical cost is not shown but a page number(s) is referenced. The page number
reference refers to Volume III - Unit Costs. Volume III contains information
and guidance on unit cost ranges, typical unit costs, and how the unit costs are
applied in various facility situations. If the user needs guidance for any clo-
sure or post-closure activities, the user should refer to the referenced pages
in Volume III.
The worksheets were designed to be as complete anc detailed as possible, so
sone of the worksheet items/sections may not be applicable to particular faci-
lity, si tuations. Tne user should ignore such sections and feel free to adjust
the worksheet formats as necessary to maximize their usefulness. The worksheets
are not intended to be used for assessing the adequacy of the closure and post-
closure plans themselves or for determining which regulations aooly to the
facility being evaluated. The user of this document should already have devel-
1-2
-------
OSWER Policy Directive
#9476.00-6
oped or reviewed the content of the closure and post-closure plans and have
determined that they are adequate before using the worksheets to prepare or
assess the cost estimates. To assess the adequacy of the plans, the user should
consult guidance documents such as permit writers' guidance manuals and tech-
nical resource documents on specific subjects. Two examples of such documents
are Closure of Hazardous Waste Surface Impoundments (SW-873) and Evaluating
Cover Systems for Solid and' Hazardous Waste (SW-867). EPA has prepared a
closure/post-closure plan guidance document that is a companion to this docu-
ment. It is entitled "Draft RCRA Guidance Manual for Subpart G Closure and
Post-Closure Care Standards and Subpart H Cost Estimating Procedures," and it
could be used as a guide for evaluating the plans themselves.
The worksheets are arranged by type of TSDF so that all of the relevant
worksheets are included for each type of waste management unit or technology.
However, an owner/operator may plan on closing more than one type of unit or
technology at a given time (e.g., closing a landfill and a surface impoundment).
Some activities, such as facility decontamination, may be performed at one time
for both units. In such situations, the user should take care to ensure that
all relevant activities are addressed but are not double-counted.

CHAPTER 2
WASTE PILE
This chapter contains the worksheets for estimating Part 264 or Part 265
closure costs and contingent closure costs (Part 264 only) for waste piles.
Applicable sections of Worksheets D-l through D-5, D-9, and D-10 should be
completed for all waste pile facilities. There may be no leachate quantity to
include in Worksheet D-2, however, because a leachate collection system is not
required (although the facility may have one). Groundwater monitoring is
required at waste pile facilities under Part 264 regulations. Worksheet D-3
should be completed (for Part 264 or Part 265) if a groundwater monitoring
program is in place at the time of closure. Worksheets D-6 and D-7 would be
applicable if there is a contaminated foundation or pad and/or containment
system to be removed, and Worksheet D-8 will be applicable if there is con-
taminated soil at the facility. If there is contaminated soil under the waste
pile and not all of the contaminated soil can be removed, the pile must be
closed as a landfill and the landfill closure cost worksheets should be used.
Under the Part 264 regulations, a contingent closure cost estimate must be
prepared for a waste pile that does not meet Part 264 liner requirements and is
not exempt from them. The contingency closure cost estimate must include the
cost of complying with the contingent closure'plan (i.e., closure as a landfill)
but is not required to include the cost of the expected closure by removal.
Consequently, only one closure cost estimate, the contingent cost estimate needs
to be prepared. Applicable sections of Worksheets D-l through D-15 should be
completed for the contingent closure cost estimate.
The waste pile closure worksheets address the following items:

CHAPTER 3
SURFACE IMPOUNDMENT
This chapter contains the worksheets for estimating Part 264 or Part 265
closure costs and contingent closure costs (Part 264 only) for surface impound-
ments. There are two options for inventory management in surface impoundments—
removing all wastes and waste residues or solidifying the waste and applying a
final cover. Worksheets E-l through E-6, E-ll, and E-13 apply to all surface
impoundments. Worksheet E-8 should be used if the wastes are to be removed.
Worksheets E-9, E-10, E-12, and E-14 should be used if the impoundment is to be
closed with the wastes left in place. Worksheet E-7 will be applicable if there
is contaminated soil at the facility.
Under the Part 264 regulations, a contingent closure cost estimate must be
prepared for a surface impoundment at which wastes are to be removed at closure
and that does not meet the Part 264 liner requirements and is not exempt from
them. The contingency closure cost estimate must include the cost of complying
with the contingent closure plan (i.e., closure as a landfill) but is not
required to include the cost of the expected closure by removal. Consequently,
only one closure cost estimate, the contingent cost estimate needs to be pre-
pared. Applicable sections of all surface impoundment worksheets except Work-
sheet E-8 should be completed for the contingent closure cost estimate.
The surface impoundment closure worksheets address the following items:
• Inventory Management

CHAPTER 6
POST-CLOSURE
The chapter contains the worksheets for estimating Part 264 or Part 265
post-closure costs. The post-closure care regulations apply to all disposal
facilities. These include:
• all landfills;
• all land treatment facilities;
• all surface impoundments at which the facility owner/operator
intends to leave waste after closure; and
• all permitted surface impoundments and waste piles at which wastes
are to be removed at closure and that do not meet Part 264 liner
requirements.
Tne cost estimates for this last group of facilities are the contingent
post-closure cost estimates. The post-closure worksheets are as follows:
• Worksheet H-l (Notation on Property Deed - Partial Closures)
• Worksheet H-2 (Notation on Property Deed - Final Closure)
• Worksheet H-3 (Maintenance of Waste Management Area Boundaries)
• Worksheet H-4 (Facility Inspection)
• Worksheet H-5 (Routine Maintenance and Repairs)
t Worksheet H-6 (Severe Erosion Damage Repair)
• Worksheet H-7 (Leachate Management)
t Worksheet H-S (Groundwater Monitoring)
• Worksheet H-9 (Gas Monitoring)
• Worksheet H-10 (Soil Monitoring)
• Worksheet H-ll (Demonstration for Exemption fron Post-Closure Care
Activities for Land Treatment Units)
• Worksheet H-12 (Certification of Post-Closure)
Worksheets H-l through H-6 and H-10 and H-12 apply to all post-closure cost
estimates. The costs for submittal of the waste record and the notation on the
6-1
-------
roncy
#9476.00-5
property deed (Worksheets H'-l and H-2) are the first costs incurred after clo-
sure is completed. These costs are sometimes included in the closure cost esti-
mate. Worksheet H-7 aoplies to those facilities with leachate collection and/or
leak detection systems, and Worksheet H-8 applies to facilities that have a
groundwater monitoring program in place at the time of closure. Worksheets H-9
and H-10 apply to landfills and land treatment facilities, respectively. Qoek-
sheet H-ll applies to land treatment units only. If the owner or operator of a
land treatment facility can demonstrate that the hazardous constituents in the
»
treatment zone have degraded before the end of the 30-year post-closure care
period, the owner or operator can become exempt for the remainder of the post-
closure care period. Worksheet H-ll would be used to estimate the demonstration
cost.
Sections 264.117U) and 265.117U) of 40 CFR state that the post-closure care
period begins after completion of each unit and must continue for 30 years.
However, Sections 264.117(a) and 265.117(a) of 40 CFR further state that the
Regional Administrator may lengthen or shorten the post-closure care period for
a facility at any time. The post-closure cost estimate for each unit must
include both the annual costs multiplied by the number of years of post-closure
care and the sum of the periodic costs. A 30 year post-closure care period was
assumed for the worksheets. If the post-closure period is lengthened or short-
ened, the user should adjust "the worksheet. The post-closure worksheets address

SUMMARY WORKSHEETS
This chapter contains the summary worksheets on which closure and post-
closure costs for each technology can be added together to produce closure and
post-closure cost estimates for the TSDF. These worksheets also include provi-
sion for reflecting regional cost differences, updating costs to current
dollars, and including appropriate fees. The summary worksheets in this section
are identical to those in Volume II, so if the user plans to use the summary
worksheets in Volume II, these summary worksheets do not need to be used. The
summary worksheets are as follows:

CHAPTER I
INTRODUCTION
This is Volume III of the Guidance Manual: Cost Estimates for Closure and
Post-Closure Plans (Subparts G and H). This volume contains information and
guidance on unit cost ranges, typical unit costs, and how the unit costs are
applied in various facility situations. The purpose of this volume is to pro-
vide guidance to the user in completing the worksheets in Volumes I and II.
Prior to using this volume, the user should review the closure and post-closure
worksheets, and based on the review of the closure and post-closure plans,
determine the applicable closure and post-closure items which need to have cost
estimates developed. For those items which the user is having difficulty in
developing the cost estimate, the user should refer to the appropriate pages in
this volume which are referenced on the worksheets.
t
The unit costs presented in this volume were developed from cost information
obtained through cost estimating manuals, EPA reports, technical publications,
contractors' bid estimates, equipment vendor specifications and contacts, and
site surveys. All costs are in 1986 dollars and are for third-party costs.
1.1 DESCRIPTION OF THE COST ESTIMATING PROCESS
This section provides a brief description of the methodology employed in
this document to develop reasonable unit cost estimates for the variety of acti-
vities encountered during facility closure and post-closure. The steps involved
in removing contaminated soils at a waste pile site and the selection of unit
costs to excavate this material are used to illustrate the cost estimating proc-
ess.
The first step in the cost estimating process is to list the specific acti-
vities to be performed by the site contractor in accomplishing a particular
task. Once these activities (or subtasks) are defined, the labor and equipment
1-1
-------
OSWER Policy DT-ecti

requirements and the corresponding unit costs for each component can be deter-
mined. The subtasks associated with contaminated soil removal and management
are:
t conduct soil sampling and analysis to determine the extent of con-
tamination and degree of health risk;
0 evaluate site and soil characteristics to determine if any unusual
or adverse conditions exist;
• select heavy equipment to excavate soil and haul it to a disposal
site;
i transport materials over a specified distance and dispose at a
commercial hazardous waste facility; and
t decontaminate heavy equipment following excavation and transport.
The next step is to select the appropriate unit cd'sts. For this example,
unit cost selection for excavating contaminated soil will be described.
On the basis of the results of the soil analysis, the area and depth of soil
to be exhumed are determined. Information on the type of contaminant(s) and
degree of risk to worker health and safety can also be assessed from the analyt-
ical results. This will help to estimate the tyoe of protective clothing and
safety equioment needed by the excavating team and the amount of surcharge added
by the site contractor to handle hazardous materials. Also, by determining the
quantity and depth of soil contamination, the appropriate excavating equipment
can be selected.
The unit cost for excavation varies by equipment type, equipment capacity,
and soil and site conditions encountered. Front-end loaders (both wheel and
tracktype) can be used for very shallow excavations only and usually are com-
bined with a dozer to provide loading. Likewise, front shovels are used for
shallow digging over a large area (as in quarries) but are not capable of deep
excavations. The most appropriate equipment type for excavation of contaminated
soils is the backhoe (also known as a hydraulic excavator). Backhoes are
capable of excavating to depths of up to 30 feet (depending on machine size) and
have common bucket capacity ratings of one-half to four cubic yards.

OSWER Policv Directive
*9476.0C-6 "
For estimating the cost of soil excavation with a backhoe, a unit cost
reference such as Means Site Work Cost Data, published annually by R.S. Means
Company, Inc., provides reasonably accurate unit costs for a wide variety of
site work activities under normal site conditions. Increased precision in the
unit cost estimate can be gained with site-specific information such as soil
type, moisture conditions, and required excavation depths when using this and
other cost references. For this example, we will assume that a medium soil type
will be excavated and loaded into trucks with a li cubic yard capacity backhoe
at a cost of S2.26 per cubic yard.
The range of unit costs for backhoe excavation in medium earth presented in
Means is SI.67 to S4.60 per cubic yard. If soft soil or sand is to be exca-
vated, 15 percent could be deducted from the unit cost of medium earth excava-
tion. On the other hand, if heavy soil or clay is anticipated, a 60 percent
increase in this unit cost would be necessary to account for decreased equipment
efficiency. In addition, if excavation in wet conditions is expected (because
of a high groundwater table or heavy rains, for example), at least 50 percent
should be added to the unit cost for excavation.
The total cost for excavating the contaminated soil at the site is not,
however, simply the unit cost of $2.26 oer cubic yard times the quantity of soil
to be excavated. It is also necessary to add costs for equipment mobilization
and demobilization, protective clothing and equipment, and a surcharge for
handling hazardous materials. Mobilization/demobilization costs, which account
for equipment delivery, set-up, break-down, and return, vary by equipment size
(i.e., greater cost for larger equipment) and can also be estimated using Means.
The cost for mobilization/demobilization of a li cubic yard backhoe is $230.
Based on the results of the soil analysis conducted prior to excavating, the
type and concentration of contaminants will be known and the degree of worker
health risk can be estimated. This information is then used by the engineer and
site contractor to select protective clothing and safety equipment for site per-
sonnel and to establish a surcharge for excavating the hazardous soils.

#9476.00-6
Costs for protective clothing and safety equipment such as respirators can
e estimated using laboratory supply catalogs such as Safety Equipment and
Supplies, published by Lab Safety Supply Company. Cost estimates for personnel
protection in hazardous environments vary significantly, depending on the sen-
sitivity of the skin and respiratory system to the hazardous materials being
handled. At a minimum, a cost of S77 per person is recommended and includes
disposable coveralls, gloves, goggles, hard hat, and a half-mask respirator.
Finally, a surcharge is often added by the site contractor either to the
unit cost of excavation (i.e., to the cost per cubic yard) or to the total job
cost to account for increased insurance (liability and medical) premiums, higher
wages for personnel, equipment modifications, safety equipment, and personnel
training. A surcharge will usually add 75 to 150 percent to the cost of normal
excavation activities,1 depending on the degree of hazard existing at the site.
We estimate a typical surcharge for contaminated material excavation to add 100
percent to the base cost of excavation.
The total cost of excavating contaminated soils under the assumptions pro-
'ided in this example can now be estimated. The following cost components are
nown:
• mobilization/demobilization of backhoe is S230;
• excavation is S2.26/yd3; a 100 percent surcharge is applied to the
unit cost of excavation so the new cost is S4.52~/yd^;
• the cost for protective clothing is estimated at $77/person times

CHAPTER 2
MONITORING AND TESTING
The Part 264 and Part 265 regulations of 40 CFR require various types of
monitoring and testing at treatment, storage, and disposal facilities during the
closure and post-closure care periods. This chapter presents the unit costs and
assumptions used in developing costs for the following: groundwater quality
monitoring, groundwater contamination monitoring, primary drinking water parame-
ters monitoring, groundwater detection monitoring, groundwater compliance moni-
toring, soil core monitoring, soil-pore liquid monitoring, testing for
contaminated soil, gas monitoring at landfill facilities, and air quality moni-
toring during incineration.
2.1 GROUNDWATER MONITORING
Sections 264.90 and 265.90 of 40 CFR require that facilities with ground-
water monitoring systems continue monitoring the groundwater during closure and
the oost-closure care period. If a tank facility is closed as a landfill,
groundwater monitoring wells will have to be constructed during the closure
period, and initial background concentrations established before groundwater
monitoring can continue. This section contains the unit costs for groundwater
monitoring.
2.1.1 Regulatory Requirements
Section 265.91 requires a minimum of four groundwater monitoring wells, at
least one well hydraulically upgradient and at least three wells hydraulically
downgradient of the waste management area. Section 265.92 requires that two
types of groundwater sampling and analysis be conducted during closure and the
post-closure care period: groundwater quality and groundwater contamination.
2-1
-------
CSWER so1icy Directive
#9476.00-5 '
Groundweter quality sampling and analysis consist of determining the con-
centration of each of the following parameters in the groundwater at each moni-
toring well: chloride, iron, manganese, phenols, sodium, arid sulfate. Section
265.92(d) specifies that groundwater quality sampling and analysis must be con-
ducted at least annually.
Groundwater contamination sampling and analysis consist of determining the
concentration or value of each of the following indicator parameters in the
groundwater at each monitoring well: pH, specific conductance, total organic
carbon, and total organic halogen. Because groundwater contamination data are
to be evaluated statistically, each determination of the concentration or value
of an indicator parameter in the groundwater sample must be based on a minimum
of four replicate measurements. Section 265.92(d) specifies that groundwater
contamination sampling and analysis must be conducted at least semi-annually.
If initial background concentrations must be established-, Section 265.92
requires that three types of groundwster sampling and analysis- be conducted:
primary drinking water parameters, groundwater quality, and groundwater con-
tamination.
Background primary drinking water parameters semolina and analysis consist
of determining the concentration of each cf the following parameters in the
groundwater at each monitoring well: arsenic, barium, cadmium, chromium, lead,
mercury, selenium, silver, pesticides (Endrin, Lindane, Methoxychlor, and
Toxaphene), herbicides (2,4-D and 2,4,,5-TP Silvex), radium, gross alpha, gross
beta, turbidity, and coliform bacteria;. Section 265.92(c) specifics that pri-
mary drinking water parameters sampling and analysis must be conducted quarterly
for one year.
Background groundwater quality and background groundwater contamination
sampling and analysis consist of determining the concentration for each of the
parameters previously mentioned. Section 265.92(c) specifies that background
groundwater quality and background groundwater contamination must be conducted
quarterly for one year.
2-2

OSWER Pol icy Directi
#9476.00-6
The Part 264 Subpart F regulations do not specify a minimum number of
groundwater monitoring wells. Section 264.91 specifies that at least one of the
following three types of groundwater monitoring programs must be instituted
during closure and the post-closure care period: detection monitoring,
compliance monitoring, or corrective action. Closure and post-closure ground-
water monitoring costs were developed for detection monitoring and compliance
monitoring only. Unless otherwise indicated in the closure or post-closure
plan, it can be assumed that during closure and the post-closure care period a
facility owner/operator would continue the monitoring program which was insti-
tuted during the operating life, either detection monitoring or compliance moni-
toring. However, if a compliance monitoring compliance period ends before the
end of the post-closure care period, detection monitoring would be reinstated
for the remainder of the post-closure period.
Detection monitoring is conducted to determine whether a regulated facility
is leaking. The parameters or constituents to be monitored are site-specific
and are specified in the Part B permit. These parameters or constituents may
include indicator parameters such as pH, specific conductance, total organic
carbon, and total organic halogen; specific waste constituents; or reaction
products that provide a reliable indication of the presence of hazardous con-
stituents in the groundwater. Section 264.97(c) specifies that the upgradient
well(s) must be sampled quarterly for one year for the monitoring parameters or
constituents to establish background groundwater quality. Costs are included in
this document in case a change in background groundwater quality is suspected
during closure or the post-closure care period and it becomes necessary to moni-
tor or re-establish background groundwater quality at the upgradient well(s); or
to establish initial background concentrations in the case of tank facilities
closed as landfills. Section 264.98(d) specifies that detection monitoring must
be conducted at least semi-annually at the compliance point (downgradient wells)
for the monitoring parameters or constituents to determine the groundwater
quality.
Compliance monitoring is conducted when it has been determined that hazard-
ous constituents are leaking from a regulated facility into the groundwater.

Tne hazardous constituents to be monitored are site-specific and are specified
in the Part B permit. A list of nazardous constituents is identified in
Appendix VIII of Part 261. Section 264.97(g) specifies that the upgradient
well(s) must be sampled quarterly for one year for the monitoring parameters or
constituents to establish background groundwater quality. Costs are included in
this document in case a change in background groundwater quality is suspected
during closure or the post-closure care period and it becomes necessary to moni-
tor or re-establish background groundweter quality at the upgradient well(s); or
to establish initial background concentrations in the case of tank facilities
closed as landfills. Section 264.99(c) states that in establishing con-
centration limits the upgradient well(s) may be sampled each time that the
downgradient wells are sampled, which is quarterly. Section 264.99(d) specifies
that compliance monitoring must be conducted at least quarterly at the
compliance point (downgradient wells) for the site-specific hazardous consti-
tuents identified in the Part B permit. Section 264.99(f) specifies that all
downgradient wells must be sampled and analyzed annually for all of the hazar-
dous constituents listed in Appendix VHI of Part 261.
2.1.2 Groundwater Quality Analysis
During the closure period, sample collection, preparation, and delivery
would be conducted by a contract lab technician. A typical time for -sample
collection and preparation is four hours per well. The unit labor cost for a
contract lab technician is presented in the chapter of this volume entitled
"Labor Categories and Rates." Groundwater quality samples would be analyzed at
a contract lab. Contract lab fees are presented in Table 2-1, which shows a

2.1.5 Detection Monitoring or Compliance Monitoring
Land disposal facilities regulated by the Part 264 regulations are required
to conduct either detection monitoring or compliance monitoring, whichever is
appropriate for the facility. Both detection monitoring and compliance moni-
toring may be performed at the same site.
During the closure period, sample collection, preparation, and delivery
would be conducted by a contract lab technician. A typical time for sample
collection and preparation for either detection monitoring or compliance moni-
toring is four hours per well. Refer to the "Labor Categories and Rates" chap-
ter of this document for a contract lab technician unit labor cost. During the
closure period detection monitoring or compliance monitoring samoles would be
analyzed at a contract lab. Because the hazardous constituents to be monitored
are site-specific, costs are given for several groups of constituents that may
be included under detection monitoring or compliance monitoring programs. The
user of this Document should select the appropriate groups of constituents from
Table 2-4 for the closure plan being reviewed. Contract lab fees for detection
monitoring and compliance monitoring analyses are presented in Table 2-4. All
cost estimates for detection and compliance monitoring should include the
following analyses because EPA expects to find the constituents at all facili-
ties:
• Inductively coupled plasma (metals);
• AA (mercury, cold vapor);
• GC (PCBs and pesticides);

2.2 SOIL MONITORING
Sections 264.280 and 265.280 of 40 CFR require that all land treatment faci-
lity owner/operators continue soil core monitoring throughout the closure and
post-closure care periods. In addition, they must continue soil-pore liquid
monitoring during the closure period for 90 days after the last application of
waste to the treatment zone. The regulations do not specify the number of
samples to be collected or the frequency of sampling for either soil core or
soil-pore liquid monitoring. This section presents the unit costs and the
assumptions used in developing the closure and post-closure costs for soil moni-
toring.

2.2.1 Soil Core Monitoring
During the closure period soil core sample collection and delivery would be
conducted by a contract lab technician. A typical time for sample collection is
one hour per sample.2 This jnciudes collecting the sample, moving between
sampling locations, and completing paperwork. Unit labor costs for a contract
lab technician are presented in the chapter of this volume entitled "Labor
Categories and Rates." The soil core samoles would be analyzed at a contract
lab. The parameters to be monitored will vary among facilities, depending on
the principal hazardous constituents contained in the waste being land treated.
Because the parameters to be monitored are site-specific, costs are given for
several parameters which may be included in the soil core monitoring program at
a facility. The user of this document should select the appropriate parameters
for the facility closure plan being reviewed from Table 2-5. Table 2-5 shows a
cost range per sample to extract liquid from soil for analysis and a cost range
per parameter for the analyses. To obtain a representative unit cost per sample
for use on the soil monitoring worksheet, the user should sum the unit cost per
parameter from Table 2-5 for each appropriate parameter to be analyzed for a
'acility. This unit cost sum equals the cost per sample for analysis. The unit
cost per sample for extraction of liauid -rorn soil should be added to the unit
cost per sample for analysis to give a contract lab fee unit cost per sample for
use on the worksheet.
During the post-closure care period sample collection and sample delivery
would be conducted by a contract lab technician. Refer to the "Labor Categories
and Rates" chapter of this volume for contract lab technician unit labor costs.
During the post-closure period soil core samples would be analyzed at a contract
lab. Refer to Table 2-5 for contract lab fees for soil core analysis.

2.3 TESTING FOR SOIL CONTAMINATION
The Part 264 and Part 265 regulations require that soils contaminated with
hazardous waste or hazardous waste residues must be removed at closure. In
order to determine if the soil is contaminated and the area! extent of con-
tamination, it is necessary to collect soil core samples at varying depths, ana-
lyze the soil samples, and prepare an isogram plan of the area! extent of soil
contamination. This section presents the unit costs of testing for soil con-
tamination.
2.3.1 Background Samples and Samples with Potential Contamination
Soil core sample collection and delivery would be conducted by a contract
lab technician. A typical time for sample collection is one hour per sample.4
Tnis includes collecting the sample and moving between sampling locations.
Unit labor costs for a contract lab technician are presented in the chapter of
this volume entitled "Labor Categories and Rates." The soil core samples would
be analyzed at a contract lab. The parameters to be analyzed to determine
whether the soil is contaminated will vary depending on the chemical properties
of the wastes that the facility receives. Because the parameter to be tested
are site-soecific, costs are given for a variety of parameters. The user of
this document should select the approonate parameters for contaminated soil
testing from Table 2-5. The user snould also refer to the contract lab fee
discussion in "Soil Core Monitoring" to obtain unit costs and time requirements

Sections 264.310 and 265.310 of 40 CFR require, as a part of landfill clo-
sure and post-closure, the monitoring and maintenance of the gas collection and
control system, if there is one present in the landfill. This section presents
the unit costs and the assumptions used in developing the costs for gas moni-
toring.
During closure and the post-closure care period gas monitoring would be con-
ducted by a contract lab technician. A typical time for monitoring a well is
0.25 hour per well. This includes time for calibration of monitoring equipment,
setting up a portable VOC monitor at the well, reading and recording the
results, and moving to the next sampling location. Unit labor costs for a
contract lab technician are presented in the chapter of this volume entitled
"Labor Categories and Rates."
Gas monitoring well inspection and well maintenance during the post-closure
care period are discussed in the chapter of this volume entitled "Inspection and

2.5 AIR QUALITY MONITORING
Sections 264.347 and 265.347 of 40 CFR require that all incinerator facili-
ties conduct air monitoring when incinerating hazardous wastes. This section
presents information regarding air quality monitoring costs.
To comply with the regulatory requirement that cost estimates be based on
third-party costs, it was assumed that if inventory is incinerated on-site the
work would be performed by contract personnel. Air monitoring must be conducted
2-17
-------
OSWER Policy Directive
#9476.00-6
throughout the entire burn time. Minimum monitoring requirements consist of
monitoring the combustion temperature, waste feed rate, the indicator of com-
bustion gas velocity, and carbon monoxide on a continuous basis. It was assumed
that instrumentation related to combustion and emission control Is automatically
controlled and that the instruments are connected to an alarm system which would
sound if steady-state conditions are riot maintained. It was also assumed that
the process operator who is present during inventory incineration (see Worksheet
C-l - Inventory Management) would monitor the instruments and would contact
appropriate personnel if the alarm sounded. Consequently, there are no addi-
tional process operator labor costs for air quality monitoring.
The emergency waste feed cut-off system and associated alarms must be tested
at least weekly to verify operability, unless the applicant demonstrates to the
Regional Administrator that less frequent inspection will be adequate. At a
minimum, operational testing must be conducted at least monthly.
Air quality monitoring data must be recorded and the records must be placed
in the operating log. It was assumed that air quality monitoring costs would
consist of the time required for a technician to test the waste feed cut-off
system, change the graph paper in the monitoring instruments daily, place the
grapns and any necessary descriptive information in the operating log, and if
necessary, select points from the graphs and record the data in the operating
log. Labor costs for facility personnel for administrative reporting are esti-
mated and documented in the "Labor Categories and Rates" chapter of this
volume.
Upon request by the Regional Administrator, sampling and analysis of the
waste and exhaust emissions must be conducted to verify that the operating re-
quirements established in the permit achieve the performance standards of
Section 264.343 of 40 CFR. Costs for this type of sampling and analysis depend
on the scope of the testing required by the Regional Administrator. Examples of
sampling and analysis plans that may be required by the Regional Administrator
are given below along with estimated cost ranges. Costs for establishment of a
Volatile Organic Sampling Train (VOST) and subsequent constituent analysis may

CHAPTER 3
INSPECTION AND MAINTENANCE
Inspection and maintenance activities are included in both closure and post-
closure of a facility. In general, the unit cost for inspections will be for a
field technician; maintenance unit costs will usually consist of a materials
cost and a labor cost for performing repairs and/or installation. During both
closure and post-closure all inspection and maintenance activities will be con-
ducted by contracted labor. Closure inspection and maintenance includes:
t routine inspection and repairs at the facility;
• repair of drainage channels at land treatment facilities; and
•
• inspection and maintenance of all monitoring, detection, and collec-
tion systems.
Post-closure inspection and maintenance activities include:
• routine facility inspections and repairs;
• repair of vegetative covers due to severe erosion damage;
• maintenance of surveyed waste management area boundary markers; and
• inspection and maintenance of all monitoring, detection, and collec-
tion systems.
The next section discusses inspection and maintenance activities that could
be part of both closure and post-closure (except repairing land treatment
drainage channels and maintaining lysimeters, which would be done during
closure). The section following it deals with activities that are performed
during post-closure only.
3.1 CLOSURE AND POST-CLOSURE INSPECTION AND MAINTENANCE
Routine maintenance and repairs during closure and post-closure consist of
various activities. Many of these activities are labor-intensive and the costs
3-1
-------

are based on the number of hours required to do them. Detailed information on
labor rates can be found in the chapter of this volume entitled "Labor Categor-
ies and Rates".
Overall facility inspection involves a technician, who does the actual
inspection, and an engineer, who supervises the technician. Administrative ser-
vices include the engineer and technician, who prepare inspection reports, and a
clerical person, who types and files the reports. Unit labor costs for these
personnel are found in the "Labor Categories and Rates" chapter of this volume.
Some closure and post-closure inspection and maintenance activities pri-
marily involve a technician to perform inspections and a laborer to perform the
necessary repairs. This is true of inspections and maintenance for the
following:
t leachate collection systems;
• leak detection systems;
t gas monitoring wells; and
t groundwater monitoring wells.
All of the inspection and maintenance work would be oerformed by contracted
labor.
3.1.1 Repair of Drainage Channels
At the time of closure, drainage channels at a land treatment facility may
need to be cleaned and repaired. Cleaning the channel involves removing depos-
its of silt and organic matter down to the original channel boundary. Sections
of the channel that have eroded must be regraded to the original contour then
revegetated to prevent further erosion. The unit cost for hand grading is $2.46
per square yard. Unit costs for revegetating the parts of the drainage channels
that have been repaired are the same as routine erosion damage repair costs
—S1334 per acre for seeding, S290 per acre for fertilizing, and $2904 per acre
for mulching.

3.1.2 Leachate Collection System Maintenance
Leachate collection system maintenance may involve replacing the pump and
cleaning out the leachate collection system branches periodically. Table 3-1
lists various sized sump pumps and their unit costs (including installation).
These pumps are automatic and have a 10-foot head. If the leachate is not very
corrosive and has a low concentration of particulate matter, the pump could be
expected to last 10 years. A leachate that is corrosive and/or high in par-
ticulates could reduce the pump life to two to five years. The need for pump
maintenance and replacement during the operating life of the facility should
provide a good guide for maintenance and replacement frequencies during closure
and post-closure.
/
Leachate collection system branches should not need to be replaced.
Sanitary sewers are designed for a 50 year life span. Leachate collection
systems should have a similar life span. The leachate collection system
branches may become clogged with fines and need to be cleaned out. Leachate
collection system branches are cleaned by backwashing with a low volume of water
under high pressure. The unit cost for cleaning out the branches is S35.35/hr.
This cost includes equipment rental and labor. The branches would not need fre-
quent cleaning during the post-closure care period because the volume of
leachate generated would be decreasing once the final cover is applied.
3.1.3 Groundwater Monitoring Well Construction or Replacement
Groundwater monitoring wells or well parts may need replacement. Ground-
water monitoring wells should last 25 years or more if the groundwater is not
very corrosive. This is based on the assumption that the well is constructed of
materials that are appropriate for the contaminants expected (e.g., stainless
steel well screening if any groundwater contamination is expected to contain
organics).
If the casing needs replacement it is more economical to seal the well
needing casing replacement and construct a new well. The unit cost for sealing
the existing well is $3/ft. A typical cost for sealing a 100-ft well would be

$300. The unit cost for constructing a new well is $2,425/well. This includes
materials (stainless steel casing, screen, pump, tubing, and cap and lock) and
installation. The well itself is two inches in diameter and is 50 feet deep.
For additional length, 534 per vertical lineal foot must be added to the unit
cost given above. A typical cost for a 100-ft well would be $4,125 plus $150
for mobilization/demobilization.
Groundwater monitoring well parts that may need replacing include pumps,
tubing, and caps. The typical costs for a teflon bladder pump is $495 and for
teflon lined tubing is $2.75/ft. A typical well cap cost is $70 per cap.
If a tank facility is closed as a landfill, the owner or operator must per-
form closure and post-closure care as a landfill. This includes implementation
of a groundwater monitoring program. Because tank facilities are not required
to have a groundwater monitoring system, it would be necessary to construct
groundwater monitoring wells during the closure period. A typical mobilization/
demobilization cost for constructing a new well is $150. A typical unit cost
for drilling and installation is $22 per vertical lineal foot. The unit cost
for two inch diameter stainless steel casing including fittings is $9/foot.
Depending on the type of soil, a well screen ranging in length from five to ten
feet may be required. The unit cost for a two inch diameter 10 foot well screen
is $290/each. The typical cost for a teflon bladder pump is S495/each. The
unit cost for teflon lined tubing for withdrawing the groundwater sample is
$2.75/ foot. A typical well cap cost is $70/cap.
3.1.4 Lysimeter Maintenance
As discussed in the "Monitoring and Testing" chapter, soil-pore liquid must
be monitored at land treatment facilities for 90 days after the last application
of waste to the treatment zone. The lysimeters used for this monitoring may
need replacement at the time of closure. The cost for replacing a lysimeter is
$132, which includes both materials and labor to prepare and replace the lysi-
meter. In addition, total costs for travel to and from the site are estimated
to be $85 per hour.

3.1.5. Security System Maintenance and Repair
Maintenance and repair of the security system during closure and post-
closure involve labor, materials, overhead, and profit. Items at the facility
that may need to be maintained or repaired include fencing, gates, posts, and
other security items such as barbed wire and signs. Depending on the layout of
the facility, fencing may have to be installed for the first time. The cost for
fencing is for industrial chain link fencing, six feet high with three strands
of barbed wire at the top. Included in this unit cost are two-inch line posts
positioned 10 feet off-center, with one and five-eighths inch top rail. The
cost for six-gauge galvanized steel fencing is $10.55 per lineal foot; without
the barbed wire the cost is $10.10 per lineal foot. These costs would be
approximately 20 percent higher if aluminized steel, rather than galvanized
steel, is used. All costs for security system items also include the labor
required to install them. The unit cost for a gate three feet wide and six feet
high with a three-inch frame made from galvanized steel is $80 per gate.
Additional corner posts for the fence, three inches in diameter, cost $57 per
post. Barbed wire unit costs range from $28 per 1000 lineal feet to $110 per
1000 lineal feet; the most typical unit cost is for 15-1/2 gauge imported steel
at $28 per 1000 lineal feet. For stainless steel helical fence topping the unit
cost is $110 per 100 lineal feet. Fencing, gates, barbed wire, and helical
fence topping should all last about 30 years, barring accidental damage or van-
dalism. However, galvanized materials will have a shorter life than this if
exposed to salty sea spray or chemical fumes (e.g., refinery emissions). In
such situations aluminized materials are recommended. The user should rely on
facility operating experience for security system life if adverse conditions are
likely.
Signs around a facility may also need replacing during closure or the post-
closure period. A standard reflectorized sign is estimated to last about seven
to eight years. As with fencing, sign life may be less than this if the sign is
exposed to salty sea spray. The user should rely on -facility operating
experience for sign life if sea spray exposure is likely. For a reflectorized
directional sign, approximately 12 inches by 18 inches, the unit cost is $21 per
sign. If a post also needs replacing, the unit cost for a 10-foot steel post is
3-6
-------
OSWER Pol icy
#9476.00-6
$29 per post, or $34 per post if a 12-foot post is needed. Signposts should
have a life of 30 years unless exposed to a corrosive atmosphere. Typical unit
costs for security system maintenance e.nd repair are presented in Table 3-2.
3.1.6 Wind Dispersal Structure Inspection and Repair
If the land treatment zone contains particulate matter which may be subject
to wind dispersal, the owner or operator must manage the unit to control wind
dispersal. The owner or operator must inspect the unit weekly and after storms
to detect evidence of improper functioning of wind dispersal control measures.
Types of wind dispersal methods may range from rows of conifers such as blue
spruce in regions with temperate climates to a polypropylene fence or screen in
regions with an arid climate. A typical unit cost for blue spruce replacement
is 5140/tree. This includes the tree and labor. A typical unit cost for a
polypropylene fence or screen replacement is $2.76/ft. As wind dispersal
control measures must be in place ove" the active life of the facility, opera-
tors can use past experience as a guide to replacement frequency.
3.1.7 Surveying and Maintenance of Waste Management Area Boundaries
One of the last closure activities performed is surveying the boundaries of
the waste management area(s) with respect to permanently surveyed benchmarks and
installing posts to mark these boundaries. The surveying would be performed by
a professional land surveyor, who would be assisted by a surveyor's assistant or
technician. A fence post would be installed to mark the boundary corners. Unit
labor costs are presented in the "Labor Categories and Rates" chapter of this
volume. Replacement of the fence posts during the post-closure period would
incur a cost of $29 per post for materials and labor. As with security system
items, fence post life should be about 30 years unless adverse conditions are
expected. Replacement frequency during post-closure should be the same as for
the fence, gates, etc.

3.2 POST-CLOSURE INSPECTION AND MAINTENANCE
3.2.1 Mowing and Sprinkling
The frequency of grass mowing and sprinkling during post-closure will vary
by region of the country, depending on the climate and precipitation. In order
to estimate these frequencies, two issues the user should keep in mind are: the
rate at which grass grows in the area in which the facility is located and the
number of months in the growing season. Upper and lower bounds that may be use-
ful for determining cover mowing frequency are residential "lawn mowing frequency
and highway maintenance (if applicable) mowing frequency, respectively. Mowing
would be done using a tractor mower. A typical unit cost would be S25 per acre
for an outside firm to do the mowing. This cost includes both equipment and
labor.
The same types of issues apply when determining a sprinkling frequency.
Sprinkling rate, -however, would probably be substantially lower for vegetative
cover areas than for a residential lawn because the main objective would be to
keep the vegetation living. Sprinkling involves driving a water tank truck to
the site and watering the vegetative cover. The daily cost, including labor and
equipment, for & 5000 gallon truck is S420. The cost for one-half day equipment
rental and labor would be S2IC. Assuming multiple trips to the site, it is
estimated that the maximum daily amount of water that could be sprinkled would
be 20,000 gallons, based on a one-way distance to the site of 10 to 15 miles.
The user will need to consider both tie quantity of water needed for sprinkling
and the distance to the site in estimating the number of days needed.
3.2.2 Fertilizing
The unit cost for fertilizing is the same as that presented in the "Final
Cover and Revegetation" chapter of this volume—$176 per acre, with an equipment
mobilization/demobilization cost of S105. Unless otherwise noted in the post-
closure plan, the user should assume that the entire vegetative cover will be
fertilized once per year.

3.2.3 Re-establishment of Vegetative Cover and Other Cover Repairs
This includes re-establishment of the vegetative final cover and repair of
routine erosion damage to the final cover, diversion ditches, dikes, and berms.
The activities are generally the same as those presented in the "Final Cover and
Revegetation" chapter — seeding, fertilizing, and mulching. However, a push
spreader is used instead of a tractor or hydraulic spreader, because it is
expected that a smaller area will need'repair. Table 3-3 presents unit cost
ranges and typical unit costs for seeding, fertilizing, and mulching using a
push spreader. Incorporated into each cost are the application rates and the
labor involved with each activity. For all routine repairs of erosion damage,
the seed used is slope mix with an application rate of 261 pounds per acre; fer-
tilizer is applied at a rate of 968 pounds per acre; and peat moss is spread one
inch deep for mulch. For re-establishing final cover in areas where the seed
germinated poorly, the application rate for seed should be approximately one-
half of the initial seed application rate (131 pounds per acre). Fertilizing
would orobably not be necessary if re-seeding is done during the same growing
season as initial seeding. If re-seeding is to be done in the subsequent
growing season, fertilizer as well as seed should be applied. The percent of
the final cover area that will need re-seeding is highly variable. Discussions
with coal companies about tneir expedience with revegetation of strip nined
areas have indicated that with good-quality topsoil and adequate post-seeding
care, no re-seeding should be necessary. In addition, experience at the faci-
lity during its operating life (e.g., establishing vegetation on berms) or with
earlier partial closures may be used as a guide for determining how much final
cover re-seeding will be necessary.
In arid regions of the country crushed stone may be used instead of vegeta-
tion for controlling erosion. Similar to vegetation, the crushed stone layer
may need to be repaired periodically due to routine erosion damage. The activi-
ties are generally the same as those presented in the "Final Cover and Revegeta-
tion" chapter -- crushed stone, except the crushed stone would be placed by hand
and compacted using a walk behind roller because a smaller area will need
repair. Table 3-4 presents unit cost ranges and typical unit costs for crushed
stone purchase, delivery, spreading, and compaction.

Both diversion ditch repair and routine erosion damage repair must include
the cost of off-site borrow if on-site borrow is not available. Enough borrrow
is needed to fill eroded areas of diversion ditches to the original contour.
The unit cost of borrow, $17.60 per cubic yard, includes purchase, delivery
(five-mile one-way haul distance), and the cost for a laborer to grade the soil
by hand.
3.2.A Repair of Severe Erosion or Frost Damage
Tne activities undertaken to repair severe erosion or frost damage to a
vegetative cover would be those to place, spread, and compact topsoil and reve-
getate the repaired area. The unit costs are the same as those presented for
native soil, purchased topsoil, revegetation, and mobilization/demobilization in
the "Final Cover and Revegetation" chapter of this volume. The frequency with
which this type of repair would need to be done should be based on such things
as the number of severe rainstorms .that occur annually in the area where the
facility is located and the amount of erosion expected during the spring
snowmelt (if applicable).
3.2.5 Rodent Control
Rodent control nas a typical unit cost of S30 per ac^e for extermination
materials; labor is provided by a contract laborer. The activity may occur with
varying frequency deoending on the geographical location of the facility and
whether burrowing rodents are expected to be a problem.
3.2.6 Maintenance of pH at Land Treatment Facilities
During the post-closure period at land treatment facilities, lime may be
needed to maintain the soil pH between 6 and 7 so that plants and microbes can
flourish in the soil. The addition of large quantities of organic wastes during
land treatment causes organic and inorganic acids to be formed and released as
the organic wastes decompose. The native soil may then become too acidic for
the waste decomposition process to continue or for the vegetative cover to grow
3-12
-------
QSWER po ; icv Directive
*9476.00-6 "
well. The cost for maintaining the pH in the desirable range depends on the
amount of rainfall in an area, the type of topsoil, and the quantity of fer-
tilizer that has been added.
A typical application rate for vegetative cover is 2.5 tons of ground
limestone per acre for the initial application plus 0.5 tons per acre every
three to six years thereafter. Over 30 years this would be one initial applica-
tion plus five to ten supplementary applications. In cases where petroleum
wastes have been applied and decomposition of the organics is complete, frequent
lime additions may be necessary to limit metals migration from the treatment
zone, particularly where the soil has insufficient cation exchange capacity to
keep the toxic metals immobilized. The typical cost for the initial application
is S214 per acre, and the cost for supplementary aoplications is S60 per acre.
mobilization/demobilization of the equipment is S105 per visit,,

CHAPTER 4
INVENTORY AND RESIDUAL MANAGEMENT
For facilities that are not engaged in disposal activities, the removal,
treatment, and disposal of inventory and waste residues will frequently be the
largest single cost element. The unit costs of inventory treatment and/or
disposal are dependent upon whether the materials will be managed on-site or
removed to an off-site commercial hazardous waste facility. If disposal or
treatment takes place on-site, the unit costs can be expected to be lower than
when removing inventory to an off-site TSDF.
This chapter presents the unit costs and prices used in developing costs for
transport, treatment, and disposal of waste inventory and residuals. It is
divided into two sections, on-site management and off-site management, to iden-
tify different practices that facility owner/operators may select to manage
their wastes. In accoraance with the regulatory requirement that cost estimates
be based on third-party costs, all activities are assumed to be performed using
contracted personnel anc equipment. Also, closure costs must include the costs
of handling, treating, and/or disposing of the maximum inventory that will be
on-site at any one time during tne operating life of the facility.
4.1 ON-SITE MANAGEMENT OF WASTE INVENTORY AND RESIDUALS
The disposal of remaining waste inventory, treatment and decontamination
residuals, leachates, and contaminated soils and other facility structures will
take place on-site at many facilities. This section contains typical costs for
a variety of on-site waste and residual management activities as well as costs
for utilities needed for the waste management processes. Utility and material
costs are listed and described in Table 4-1. Cost estimates for specific on-
site waste and residual management activities using third-party labor and rental
equipment are described in the following sections.

4.1.; Impoundment
Three dewatering methods were considered for removing standing liquids from
the impoundment.
• Solar evaporation - Solar evaporation is feasible only in specific
areas and times of the year. Cost estimates will likely be based on
normal annual maintenance costs (which are highly variable) and the
length of time required for evaporation. The only cost guidance
available is $0.045 per gallon of impoundment capacity, which is
based on a 10-year average life cycle cost for an impoundment.
• Pumping out - Dewatering can be accomplished by Dumping the free
liquids to another impoundment not undergoing closure or by pumping
into tank trucks for transport to an off-site disposal facility.
Costs to rent and ooerate pumps with third-party labor are provided
in Table 4-2.
i Discharge to POTW - Assuming that the surface impoundment is con-
nected to a sewer and the facility is permitted for discharge, the
rate is SI. 50 per 1000 gallons.
4.1.2 Impoundment Sludge Removal
Sludge may or may not be removed from the impoundment following dewatering
(as described above) and air drying of the sediment. If the sludge cannot be
dried enough to allow heavy ec-^pment to enter the impoundment, a dragline
(positioned at the edge of the impoundment) would be used to remove the sluage.
An alternative method for wet sludge removal is to use a portable floating
dredge which augers the sludge and then pumps it to shore.
Table 4-3 provides cost estimates per cubic yard of sludge removed and truck
loaded using off-site labor and various heavy equipment. Mobilization/demobil-
ization costs for the appropriate heavy equipment should also be included. Once
the contaminated material has been removed, costs for transport and disposal
will also be incurred as discussed later in this section.

4.1.3 Impoundment Sludoe Stabilization
If the sludge is to remain in place, stabilization is done to ensure that it
is sufficiently consolidated to provide long-term support for cover materials.
Before the sludge can be stabilized, however, impoundment dewatering must first
be performed. Many of the solidification techniques are proprietary and highly
waste-specific, resulting in a wide range of costs for stabilization. Because
of the importance in selecting the proper solidification technique for the waste
type and quantity, it is assumed that the facility would contract with a company
providing this service. The estimated price range for waste solidification is
S35 to S165 per ton of sludge, depending on the level of pretreatment required.
Another study indicated the price to be approximately S100 per ton when worker
health and safety costs were added to the base (non-hazardous) price of solidi-
fication. If information on the cost of solidification is not provided, an
estimate of S100 per ton of sludge should be used.
4.1.4 Waste Pile Removal and Loading
The costs to remove wastes from the v.aste pile area and to load them onto a
truck for transport and disposal are presented in Table 4-4. These costs are
for off-site labor and neavy equipment. In addition, Table 4-4 contains heavy
ipnent rnoti 1 ization/3emc3"i i izetion costs.
4.1.5 Containerization of Bulk Wastes
The containerization of bulk liquid wastes frorr, an elevated tank is assumed
to be accomplished by moving an empty 55-gallon drum under the tank, opening a
valve, and allowing the drum to fill. When the drum is full the valve is closed
and the drum is sealed and moved onto a pallet. The time needed to fill and
seal each drum is estimated to be 15 minutes per drum. The cost for con-
tainerization, including third-party labo", drums, and rental of a drum lift for
moving the filled drums, is estimated to be $69 per drum.
The containerization of bulk solid wastes into SB-gallon drums is assumed to
be done by hand. The waste material is shoveled into a drum and the drum is

4.1.6 Recontainerization of Containerizec Waste
Drums that are leaking must be handled such that the leaking materials will
be contained. In such situations, the entire SB-gallon drum will be enclosed in
an SB-gallon salvage drum instead of emptying the contents of the leaking drum
into a new drum. A drum lifter is used to hoist the drum into the air so that
it can be lowered into the salvage drum. Assuming it takes 20 minutes per drum
to lift and place the SB-gallon drum into the salvage drum, seal the salvage
drum, and load it, the total cost (including the cost of a new salvage drum) is
S144/drum.
4.1.7 Container Inventory Quantity
The Quantity of inventory to be managed must include full and empty con-
tainers as well as the waste. It is assumed that empty containers will be
managed in one or three ways. Tne empty containers may be disposed or with the
full containers or they nay be triple-rinsed then recycled or disposec of in a
sanitary lane*ill. An average container weight of 55 oounds must be added to
the auar.tity of material to be managed i* the containers are to oe disoosed cr
with tne waste. If the rinsed containers are to be recycled, no revenue is
assumed.
4.1.8 Container Loading
The time requirement for moving and loading SB-gallon drums varies with the
type of equipment and the distance from the storage area to the truck. Assuming
that a pallet holds four SB-gallon drums and the number of non-palletized drums
is negligible, approximately 10 pallets or 40 containers can be loaded in an
hour. This includes the time to briefly inspect, record, transport, and load
each pallet of drums. The cost for this activity is $4.66 per pallet, which
4-8
-------
OSWER Pol icy Directi

includes labor, equipment, and operating costs. A fully loaded trailer of 80
drums would take two hours to load, at a total cost of $93.
4.1.9 Landfill Inventory/Residual Disposal
The cost to place remaining waste inventory or residuals in an on-site land-
fill is based on cost of heavy equipment operated by third-party laborers.
These cost estimates, presented in Tables 4-5 and 4-6, are appropriate for
placing bulk solids or containerized waste in a landfill cell or trench.
Mobilization/ demobilization costs for the heavy equipment are also included in
the tables.
4.1.10 Absorption of Free Liquids in Containers
Free liquids must be absorbed or solidified if they are to be landfilled.
This is accomplished by third-party laborers prior to on-site disposal.
Assuming that each drum with free liquid has sufficient space to add absorbent
material, a reasonable cost for stabilization would be S7 to S16 per drum,
including labor and materials. Tnis cost range assumes that the drum contains
between one inch (about two gallons) and six inches (10 gallons) of free
liquids. A typical cost of S10.50 per drum for absorbing three inches (n've
gallons) of free liquids is suggested.
Solidification is the only pretreatment method that is assumed to be used
for containerized waste. Solidification is only necessary if the waste is to be
disposed in a landfill. It is assumed that no pretreatment is needed if waste
is to be incinerated or if it is to be treated at a land treatment facility.
4.1.11 Sludge Dewatering Prior to Landfill Disposal
Excavation sludges may be dewatered before on- or off-site disposal if a
filter press is present on-site. Costs for industrial sludge dewatering using a
belt filter press include labor, utilities, and materials. The cost is S5.50
per wet ton of sludge processed. Sludge is dried to approximately 30 percent
solids content. Assuming an initial solids content of 5 percent, the final
dewatered sludge quantity is one-sixth (0.17) of the original (wet) sludge
amount.

4.1.12 Solidification of Bulk Wastes Prior to Landfill Disposal
Certain wastes containing free liquids must be solidified on-site if they
are to be disposed in a landfill at the facility. In general, this can be
accomplished by the addition of cement or fly ash to the waste and batch mixing
in a powered concrete mixer. The cost estimates prepared for this activity are
based on the use of third-party labor and equipment and include the purchase of
cement or fly ash. A processing rate of 1.5 tons per hour is estimated. The
resulting costs are SSI per ton for cement-based solidification and S55 per ton
for wastes solidified with fly ash. Approximately a 100 percent weight increase
should be expected.
4.1.13 Leachate/Run-Off Removal
The cost for the removal of leachate, run-off, or other hazardous liquids
collected in on-site sumps or tanks is estimated for both closure and post-
closure periods. These cost estimates are based on contracted labor rates and
pump operating costs. If no pump is presently installed on-site, a pump rental
fee must be added to the cost of closure pumping. For post-closure, Dump rental
is assumed. The oumo capacity is 8000 gallons per hour.
• ClosJre purr.ping: S23.GO oer hour (oljs optional S2.7C oe- hour purric
rental)
c Post-closure pumping: $25.70 per hour
4.1.14 Landspreading cf Inventory/Residuals
Costs for on-site landspreading both liquid and solid waste using third-
party labor and equipment were estimated. For liquids and wet sludges which can
be pumped, the cost is S6.50 per ton. The mobilization/demobilization cost for
a sludge applicator truck is S150. For solids which must be spread and disked
into the soil, the cost is $9.25 per ton. Experience from facility operating
life should be used to determine the waste application rate in tons/acre. The
cost for mobilization/demobilization of a tractor with disking attachments is
$125. To provide soil conditioning and pH control, ground limestone is spread
with third-party equipment and labor at a cost of $214 per acre.
4-11
-------
^ r u I P ;
#9475.00-6
During the closure period at land treatment facilities, the soil must be
kept aerated so that the soil microbes will remain active. As the soil settles,
the microbes use their available oxygen. Without replenishment of oxygen from
the surface, the soil may go anaerobic. Periodic disking is used to turn and
loosen the soil to optimize conditions for biodegradation by keeping it aerated.
Frequency of disking to assure adequate aeration should be based on historical
operating experience, because it will be dependent on waste type, soil type, and
the amount of precipitation in the region. The typical cost for renting and
operating at tractor with a disk attachment is $14.40 per acre.
4.1.15 Incineration of Inventory/Residuals
The cost for incineration of inventory on-site is primarily a function of
the labor, auxiliary fuel, electricity, and lime costs. Unit costs for utili-
ties and other supplies are presented in Table 4-1, and the unit labor cost for
a process operator is $25 per hour (see Table 9-1). In addition to operating
the incinerator, the process operator is also responsible for inspecting the
incinerator and its associated equipment daily (40 CFR §§264.347 and 265.347)
and the waste feed cut-off weekly (40 CFR §264.34";.
The ash generation rate is a function of the physical state of the waste ard
ho.,' well it burns, which car, oe quite variable. If no waste-specific infor-
mation is provided, the user can select from the recommended ash generation
rates of 0.19 tons per ton of waste for solid wastes, 0.11 tons per ton for
slurry wastes, and 0.03 tons per ton for liquid wastes.
4.1.16 Treatment of Liquid Inventory/Leachates/Residuals
Costs for on-site treatment of wastes, leachates, and/or residuals are
highly variable and are a function of the intrinsic waste characteristics,
treatment system capacity, and residual quality. Waste type and constituent
concentrations, as well as whether a waste is highly toxic, corrosive, igni-
table, or reactive, will dictate a variety of handling and treatment processes.
4-12
-------
^9475.00-5
Tre£tTient system conpiexity and size are determines by waste volume, physi-
cal form (some wastes may require pretreatment steps such as filtration), and
the number and type of constituents which must be treated. These factors deter-
mine system design and engineering, equipment selection, labor assignments,
chemical and energy requirements, and residual management costs. Due to the
variability of these factors, it is not possible to reasonably estimate on-site
treatment costs. Operating cost information (e.g., labor hours and rates, chem-
ical costs, energy use expenses, and residual management costs) should be
obtained from facility records and be used to estimate the costs of on-site
waste treatment during closure and post-closure periods.
4.2 OFF-SITE MANAGEMENT OF WASTE INVENTORY AND RESIDUALS
The disposal of remaining waste inventory, treatment and decontamination
residuals, leachates, ana contaminated soils, liners, and other facility struc-
tures may be accomplished off-site at a commercial Hazardous waste facility.
This section contains typical prices for transportation and to landfill, incin-
erate, inject, landspread, or treat the waste at commercial facilities.
£.2.1 Transportation Prices
Estimates have beep c^eoar-ec ~or the price tc fansoort three different
waste types—bul< solids, bulk liauids, and containerized urastes--over a range
of one-way haul distances. Full net loads for these trucks range from 20 to 25
tons, resulting in combined weights which do not exceed the legal limit of
80,000 pounds GVW. The key assumptions used in developing these price estimates
are presented in Table 4-7, for a 250-mile haul. If information on haul dis-
tances to commercial hazardous waste management facilities is not available, a
typical one-way haul distance of 250 miles is suggested. A minimum one-way
distance of 25 miles should be assumed. Price estimates are reported in dollars
per one-way mile and are shown in Table 4-8. These estimates include the costs
of waste shipment to a hazardous waste treatment or disposal facility as well as
the costs for the return trip.

4.2.2 Landfill Prices
Price estimates have been prepared for the landfill disposal of solid
hazardous wastes. Two price estimates are given to account for price variations
for waste in which free liquids are presert and must be solidified. EPA regula-
tions state that waste containing free liquids must not be placed in a landfill.
Therefore, containers holding free liquid1; must have all such liquid solidified
with absorbent so that liquid is no longer observed.
Landfill disposal price estimates are reported in dollars per ton for wastes
with no free liquids (i.e., bulk and containerized solids) and waste's with free
liquids (i.e., bulk liquids and containerized liquids/sludges) that require
solidification prior to disposal. These price ranges and typical price esti-
mates, which are shown in Table 4-9, are based on the following key assumptions:
• cost estimates are based on commercial capacity, personnel, and
equipment and operating requirements;
• landfill annual capacities range from 15,500 tons to 135,000 tons;
• landfill operating life is 20 years (20 cells);
• landfill has a double-lined containment system (synthetic membrane
and clay) with leachate collection and removal;
e landfill cover svste" is douple-linec (synthetic membrane and clav';;
and
• estimated unit costs of disposal (S/ton) are increased 100 percent
to reflect commercial disposal prices.
Resulting price estimates were compared to reported values from an
EPA-sponsored survey of the commercial hazardous waste industry in 1984 and
current prices being charged by a commercial vendor.
4.2.3 Incineration Prices
Prices for commercial hazardous waste incineration are highly variable due
to pricing structures based on waste type (liquids, solids, sludges), packaging
(bulk or containerized), waste characteristics (percent halogen, moisture con-

tent, BTU value, viscosity), and quantity of residuals generated after -incinera-
tion (ash, scrubber sludge). A range of prices, as well as a typical price, for
commercially incinerating various waste types have been estimated and is pre-
sented in Table 4-10. These price estimates are reported in dollars per ton and
were obtained through EPA-sponsored survey efforts conducted in 1984. The typi-
cal estimates reported reflect current (1986) prices being charged, based on
price information provided by a commercia' vendor.
4.2.4 Deep Well Injection Prices
Prices charged for deep well injection generally vary with the toxicity of
the waste, amount of solids in the waste stream, and the degree of pretreatment
required prior to injection. A range of prices for deep well injection for two
different waste streams is presented in Table 4-11 both in dollars per gallon
and dollars per ton. A typical price in 1986 dollars is also estimated.
4.2.5 Land Treatment Prices
Prices for commercial land treatment vary apcording to waste type and
hazardous constituent concentration, as well as the soil type and the capacity
of the treatment facility. A range cf crices for commercial land treatment is
oresented in Table 4-12. A tynical orice in 1986 dollars is also presented. It
should be noted tnat this method of treatment is available only for a limned
number of waste types. The waste streams that are most typically land treated
include oily sludges, gum and wood oroducts, and some organics.
4.2.6 Treatment Prices
Prices for commercial treatment of waste are highly variable and waste
stream specific. The presence of cyanides, heavy metals, or highly toxic
constituents in waste is a reflected by a substantial price increase for treat-
ment. A range of prices for waste treatment for three types of waste streams is
presented in Table 4-13. These figures are reported both in dollars per gallon
and dollars per ton. A typical price in 1986 dollars is also presented.

CHAPTER 5
EQUIPMENT AND FACILITY DECONTAMINATION
Sections 264.114 and 265.114 of 40 CFR require, as part of closure, that all
facility equipment and structures be properly disposed of or decontaminated by
removing all hazardous wastes and residues. This chapter presents the unit
costs for equipment and facility decontamination conducted by third-party per-
sonnel. Costs for excavating contaminated materials and disposing of remaining
hazardous wastes and residues are presented in the chapters entitled "Demolition
and Excavation" and "Inventory and Residual Management," respectively. For more
information on equipment and facility decontamination refer to EPA/600/2-85/028
March 1985, Guide for Decontaminating Buildings, Structures,-and Equipment at
Superfund Sites.
5.1 EQUIPMENT DECONTAMINATION
5.1.1 Heavy Equipment
Unit costs for the decontamination of heavy equipment are calculated by con-
sidering third-party labor costs, steamcleaner rental cost, and hourly operating
cost. These unit costs are presented in Table 5-1. Residual is generated at
the rate of 100 gallons per hour. Treatment and disposal of residuals are
discussed in Chapter 4, "Inventory and Residual Management."
5.1.2 Pumps and Feed Lines
Unit costs for decontaminating pumps and feed lines consist of the time
required for both set-up and mixing the cleaning solution (usually alkaline) and
final rinsing with water. The base time for set-up, mixing, and cleaning of a
pump and its associated line is eight hours. For each additional pump (and
line) another four hours are required. The volume of cleaning fluid and rinse
water required for each pump and line is estimated at 50 gallons. This document
assumes that the cleaning fluid and rinse water will be treated as a hazardous

waste. Treatment and disposal costs for these residuals are presented in the
chapter entitled "Inventory and Residual Management." Table 5-2 presents the
costs for decontamination and the residual quantities generated for up to four
pumps and lines.
5.2 FACILITY DECONTAMINATION
5.2.1 Tanks and Other Facility Structures
These include tank interiors, the interstitial space between double-walled
steel tanks, vault system interiors, sumps or troughs, waste pile foundations,
and other areas where wastes were managed. Concrete or asphalt slabs which will
remain in place should also be decontaminated. Residuals generated from
cleaning of facility structures are assumed to be treated as hazardous wastes.
Tank cleaning costs are estimated in dollars per unit area. To,assist the user
in estimating tank cleaning costs, TaDle 5-3 presents a summary of surface areas
compared with tank capacities for vertical and horizontal tanks ranging in size
from 5000 to 30,000 gallons.
Tne following three cleaning methods and unit costs are considered
appropriate for decontamination of tanks and other facility structures:
• Steamcleaning - an average of 50 square feet of surface area is
cleaned per hour at a cost of $0.55 per sauare foot. Residual is
generated at a rate of approximately four gallons per square foot.
• High-pressure washing - an average of 40 square feet of surface area
is cleaned per hour at a cost of of $0.88 per square foot. Residual
is generated at a rate of approximately four gallons per square
foot.
• Sandblasting (dry system) - an average of 50 square feet of surface
area is cleaned per hour at a cost of $0.62 per square foot.
Residual is generated at a rate of approximately two pounds per
square foot.
Management of decontamination residues is discussed in Chapter 4, "Inventory
and Residual Management."

In addition, protective clothing and safety equipment are necessary for per-
sonnel involved in decontamination procedures. A cost of $80 per person is
estimated and includes a splash suit, shoe covers, apron, gloves, goggles,
respirator (half-mask with air purifying cartridges), and hard hat. This cost
would be applicable for all decontamination activities except interior tank
cleaning when it is necessary to enter the tank. If tank entry is anticipated,
another four hours per tank and additional safety equipment are required. Labor
costs are S23.00 per hour. The additional equipment replaces the half-mask
respirator with a chest style, full-face respirator and organic vapors/acid gas
canister at an additional cost of $172 pe'" person.
The cost of bulk tank cleaning ooe'-ations can vary significantly due to
health and safety considerations. Tne unit costs discussed above for tank
cleaning may be considerably understated depending on the degree of hazard
expected when tank entry is necessary. It is quite conceivable that additional
protective clothing, a self-contained breathing apparatus, and other safety pro-
cedures (i.e., buddy system, organic vapor monitors, emergency equipment, etc.)
will De necessary. Incremental health and safety costs for bulk tank cleaning
may add from 100 to 300 percent to the cost of normal (non-hazardous) cleaning
operations. If hazardous working concifons are anticipated and the cost esti-
mate does not adequately aaciress worker healtn and safety considerations, a 200
percent surcharge shculc be included.
5.2.2 Tanks and Vaults Left in Place
Underground tanks can be removed and salvaged after decontamination or they
can be left in place. If they are left in place they may be filled with sand.
If the underground tank is contained in a vault system, the vault system may
also be filled with sand. However, in both of these cases filling with sand is
not a regulatory cost. If an underground tank is left in place and the tank is
closed as a landfill, the tank would be filled with sand in order to provide
structural integrity for the landfill cover. Similarly, if the underground tank
is contained in a vault system and the tank is closed as a landfill, both the
tank and the vault would be filled with sand to provide structural integrity for
the landfill cover. In both of these cases filling with sand would be a regula-

tory cost. The unit cost for this procedure, including sand and labor, is $0.10
per gallon of tank and vault capacity.
5.2.3 Tank Removal
Three types of tanks can be used for treatment or storage of hazardous
wastes. The three types are onground (aboveground), inground, and underground.
Refer to Figures 1-13 of the, preamble of the proposed tank rules in the Federal
Register, Vol. 50, No. 123, June 26, 1985, pp. 26465-26481 for examples of these
three types of tanks and their secondary containment systems. Onground and
underground tanks are typically constructed of steel or fiberglass, while
inground tanks are generally constructed of concrete.
Tanks are generally removed under the following circumstances: if the
secondary containment system is contaminated; if necessary to remove con-
taminated soil; and for onground tanks if the tank area is closed as a
landfill.
In order to remove inground tanks or underground tanks in a vault system a
cover may need to be removed. The cost for cover removal can vary depending on
the cover material, size, and type of seal. A small cover can be moved with a
backhoe or front-end loader. Generally, there is nc cost for moving a small
cover because the backhoe or front-end loader would typically be on-site, and
hooking the cover and moving it would only require a few minutes time. A large
cover would typically be moved with a crane. A jackhammer may also be needed to
loosen the cover before moving. Cover removal with a crane and jackhammer can
range from S150-S300/hr plus $200 for mobilization/demobilization. A typical
time and unit cost for moving a cover is 1 hour at $200/hr plus $200 for
mobilization/demobilization. Concrete vaults with a cast-in-place cover will
require cover demolition to remove the tank(s). Unit costs for concrete demoli-
tion are estimated at $3.70/ft^ of cover surface area.
Some underground tanks may be covered with soil. In order to remove the
tank, the soil must be excavated. Unit costs for soil excavation are presented
in Chapter 6, "Demolition and Excavation."

face area are loosened from a concrete pad with a jackhammer or cut from steel
supports and moved off the pad with a crane. Field erected steel tanks greater
than 700 ft2 in surface area are loosened from a concrete pad with a jackhammer
or cut from steel supports, cut into sections with a cutting torch, and set
aside with a crane. The unit costs for moving tanks are presented in Table 5-4.
To assist the user in estimating tank surface area, Table 5-3 presents a summary
of surface areas for vertical and horizontal tanks ranging in capacity from
5,000 to 30,000 gallons. The user should note that the worksheet allows only
one line for tank surface area for tanks being removed. On the worksheet the
surface area is multiplied by a unit cost selected from Table 5-4 to estimate
the total tank removal cost. If more than one tank is to be removed, the user
must determine one surface area to represent each of the tanks being removed
before selecting a unit cost from Table 5-4. If the user does not select a unit
cost which is representative of tank size, an incorrect removal cost would be
calculated. For example, if three tanks at 100 ft2/tank were to be removed, the
r\
user would enter 300 ft^ on the worksheet for tank surface area. The
appropriate unit cost from Table 5-4 would be $5.80/ft2 because the surface area
of each tank is 100 ft2. The tank removal cost would be 'S5.80/ft2 x 300 ft2 =
51740.
Jnground tanks are removed by demolition with a hydraulic hammer attached to
a backhoe. Some work may have to be clone manually with a jackhammer. The demo-
lition unit cost for mesh reinforced concrete is $76/yd^,, while for rod rein-
forced concrete it is S105/yd3. Demolished concrete located below grade is
typically truck loaded with a backhoe. Unit costs for truck loading of demol-
ished concrete are presented in Table 6-1 of Chapter 6.
Underground tanks are removed with a crane. In some cases the tank must be
cut loose from supports before lifting. The unit costs for moving tanks are
presented in Table 5-4. Similar to onground tanks, the user must select a unit
cost that represents the average surface area of all the tanks being removed.
In areas where an underground tank will be subjected to water conditions the
tank may be anchored to a concrete slab or deadman. The slab may or may not

need to be removed with the tank depending on whether the soil surrounding the
slab has been contaminated. If contamination has not reached beyond the anchor
slab the anchor straps are cut, the tank is removed, and the slab is left in
place.
The unit costs for demolition of a concrete slab or deadman and the unit
costs for loading the demolished concrete with a backhoe are presented in
Chapter 6, "Demolition and Excavation."
5.2.4 Container Rinsing
The unit cost for triple rinsing empty SB-gallon containers with a sprayer
is estimated as $32.75 per hour. This cost includes labor, equipment, and
operating costs. Drums are assumed to be cleaned at a rate of five minutes per
drum. Container rinsing generates an estimated 10 gallons of residual per drum.
The cost of cleaning solutions is negligible and is therefore not included in
these estimates.
5.2.5 Incinerator Refractory Removal
The cost for removing the refractory (fire brick) from the primary com-
bustion chamber of an incinerator is estimated at S3.20 per square foot of sur-
face area. Costs for rubble disposal must be added as found under Chapter 4,
"Inventory and Residual Management." The incinerator refractory weighs approxi-
mately 33 pounds per square foot of surface area.
5.2.6 Off-Site Management of Rinsed Containers
Rinsed containers may be disposed of in a sanitary landfill. Tipping fee
costs for sanitary landfills are assumed to be $12/ton.
5.2.7 Demonstrating Success of Decontamination
The success or adequacy of decontamination of facility structures and equip-
ment must be evaluated. The level of decontamination necessary to satisfy the

closure performance standard will serve as the benchmark for determining decon-
tamination success. The structure or equipment must be cleaned, washed, and/or
rinsed as many times as necessary to achieve a contaminant concentration in the
last rinse water equal to that of the closure performance standard. Costs asso-
ciated with determining the success of decontamination include the cost to
collect rinse water samples and to determine the concentration of the hazardous
constituents in the rinse water. Costs for determining the concentration of
hazardous constituents are the same as the contract lab fees for groundwater
quality analysis found in the chapter entitled "Monitoring and Testing".

CHAPTER 6
DEMOLITION AND EXCAVATION
The demolition and removal of facility structures and the excavation of
soils, containment systems, and subsoils may be required to properly decon-
taminate and close the facility. This chapter presents the unit costs and
assumptions used in developing cost estimates for the removal of contaminated
facility structures and soils by independent site work contractors.
6.1 PAD OR FOUNDATION DEMOLITION
Unit costs to breakup and load & concrete or bituminous pad vary with pad
thickness, accessibility, and equipment selected to perform the task. Demoli-
tion of reinforced foundations up to six inches thick using power equipment
(i.e., a backhoe loader with a hydraulic hammer) costs approximately S23.50 per
cubic yard. Reinforced foundations ranging from seven to 24 inches thick, on
tne otner hand, cost S105 per cubic yard to remove. If hand-held air equipment
must be used, the demolition costs for mesh reinforced foundations range from
$76 to SS7 per cubic yard. We estimate that the typical cost for contaminated
pad removal is $82 per cubic ya>"d, based on expected pad thickness, relatively
small job size, and accessibility that may limit the use of power equipment.
Unit costs for truck loading of the demolished pad are presented in Table 4-4 of
the chapter entitled "Inventory and Residual Management."
If concrete or asphalt slabs are cracked or damaged, the soil beneath them
may be contaminated. This requires that soil samples be taken beneath such
areas. This can be accomplished by core drilling through the slab at a cost of
$15 per inch of slab thickness. Sample testing costs are found in Chapter 2,
"Monitoring and Testing." If contamination is found, the slab should be opened
to remove the contaminated soil.

6.2 EXCAVATION OF CONTAMINATED SOILS AND CONTAINMENT SYSTEMS
Surface soils, impoundment sediments, containment liners, vault systems, and
subsoils contaminated by exposure to waste materials through spills, leaks, and
long-term containment (e.g., a primary liner) will require management as a
hazardous waste. If contamination is suspected at the site, a cost for soil
testing should be included in the closure cost estimate to verify and determine
the extent of existing contamination (see chapter entitled "Monitoring and
Testing" for appropriate unit costs). Once the contaminated materials have been
excavated, costs for transport and disposal will also be incurred. Unit cost
guidance for transport and disposal services is provided in the chapter entitled
"Inventory and Residual Management."
Three methods of excavation are presented for removal of surface soils,
impoundment sediments, containment liners, and subsoils: hydraulic backhoe,
front shovel, and a dozer coupled with a front-end loader. Each method of exca-
vation includes truck loading but not transportation costs. The unit costs for
excavation using each equipment type under varying soil conditions are sum-
marized in Table 6-1. The individual unit costs for excavation are presented in
Figures 6-1 through 6-4.
Vault systems are a type of secondary containment system for underground
tanks. Vault systems are removed by demolition of the concrete walls. The
vault walls must be broken up with a hydraulic hammer attached to a backhoe.
The demolition unit cost for mesh reinforced concrete walls is S76/yd^ and for
rod reinforced concrete walls it is SlOS/yd^. Demolished concrete located below
grade is typically truck loaded with a backhoe. Unit costs for truck loading of
the demolished vault walls are presented in Table 6-1.
New onground (aboveground) tanks can be supported by a concrete ringwall
located below grade next to the external liner system. If the secondary con-
tainment system must be removed and contaminated soils beyond the secondary con-
tainment system must be removed, it would be necessary to remove the concrete
ringwall. The demolition and truck loading cost would be the same as for a
vault system.

6.3 OTHER COSTS
6.3.1 Mobilization/Demobilization of Heavy Equipment
This cost is added by the site work contractor to transport heavy equipment
to and from the site. Mobilization/demobilization costs apply to both demoli-
tion and excavation if heavy equipment is used. The range and average cost for
each equipment type are shown in Table 6-1. Additional detail on mobilization/
demobilization costs for specific sizes of heavy equipment is provided in
Chapter 4, "Inventory and Residual Management."
6.3.2 Protective Clothing and Safety Equipment
Workers involved in demolishing and excavating contamianted" materials should
be provided with appropriate clothing. A cost of S77 per person is estimated
and includes total body coveralls, gloves, goggles, respirator (half-mask), and
ha^d hat.
6.3.3 Heavy Equipment Decontamination
After completion of demolition and excavation activities the contractor's
equipment must be decontaminated. Unit cost estimates for equipment decon-
tamination have been prepared by equipment type and appear in Table 5-1 of the
chapter entitled "Equipment and Facility Decontamination." Management of
decontamination residues is discussed in Chapter 4, "Inventory and Residual
Management."
6.3.4 Surcharge for Handling Contaminated Materials
A surcharge may be added by the site contractor either to the unit cost of
demolition/excavation (i.e., cost per cubic yard) or to the total job cost to
account for increased insurance (liability and medical) premiums, higher wages
for personnel, equipment modifications, safety equipment, and personnel
training. A surcharge, if applied, will usually add 75 to 150 percent to the
6-8
-------
OSWER Policv Directive

cost of normal excavation activities, depending on the degree of hazard existing
at the site. We estimate a typical surcharge for contaminated material excava-
tion to add 100 percent to the base cost.

#9476.00-6
CHAPTER 7
FINAL COVER AND REVEGETATION
7.1 REGULATORY REQUIREMENTS
Parts 264 and 265 of the RCRA regulations require final cover and revegeta-
tion as part of closure for land disposal facilities. Specifically, Sections
264.310 and 265.310 require that all landfills have a final cover. Sections
264.228 and 265.228 require, for surface impoundments in which wastes are left
in place at closure, that: 1) the wastes be solidified or stabilized to a
bearing capacity sufficient to support a cover; and 2) a landfill cover that
meets the requirements of Sections 264.310 or 265.310 be placed over the waste.
Sections 264.258 and 265.258 require that waste piles in which not all con-
taminated subsoils can be practicably removed or decontaminated after all reaso-
nable efforts, be closed according to the landfill closure requirements.
Section 264.280 requires that land treatment facilities must establish a vegeta-
tive cover (unless the level of hazardous constituents in the treatment zone
soil does not exceed background), and Section 265.280 requires that land treat-
ment facilities must have a final cover that controls infiltration, erosion,
run-off, and wind erosion.
Sections 264.221 and 264.301 require that each new surface impoundment and
landfill, each new unit at an existing facility, each replacement of an existing
unit, and each lateral expansion of an existing unit must have two or more
liners. Sections 265.221 and 265.301 require that each new unit, replacement
of an existing unit, or lateral expansion of an existing unit receiving wastes
after May 8, 1985 must have two or more liners. EPA has specified the two liner
system to consist of a top synthetic liner and a lower recompacted clay liner.
The preamble to the July 15, 1985 regulations states that each double-lined cell
must be closed with an equivalent cap implying a synthetic liner and clay layer.
Landfills and surface impoundments regulated by Part 265 regulations which
ceased receiving waste beginning May 8, 1985 do not have to have any liners.
Consequently, either a single clay or single synthetic liner in the cap is suf-
ficient.
7-1
-------
OSwER Pol icy Direct i ve
.00-6 "
AH Part 264 and Part 265 landfills and surface imooundments receiving
wastes after May 8, 1985 would need to have a final cover consisting of the
following layers in ascending order from the layer closest to the waste.
(1) Native soil which is used to bring the active area to the
appropriate grade and establish a foundation for the final cover.
(2) Clay layer to provide long-term minimization of precipitation
Infiltration and leachate generation.
(3) Synthetic membrane to avoid the build-up of liquids in a closed
cell and to provide short-terrr prevention of infiltration.
(4) Drainage layer with tiles to oremote drainage of the final cover.
A sand drainage layer is recommended because gravel could puncture
the synthetic membrane. Three types of drainage tile can be used:
PVC, concrete, or vitrified c'ay.
(5) Geotextile filter fabric which is placed on top of the drainage
layer to prevent clogging of the drainage tiles.
(6) Tcpsoil which is used to support vegetation.
(7) Revegetation which provides ground cover to minimize soil erosion.
Revegetation consists of seeding, fertilizing and mulching.
A final cover for a Part 265 landfill or surface impoundment which ceased
receiving wastes beginning May 8, 1985 but has not been closed would consist of
the following layers in ascending order from the layer closest to the waste.
(1) Native soil which is used to bring the active area to the
aopropriate grade and establish a foundation for the final cover.
(2) Low-permeability layer which consists of either clay or a synthet-
ic membrane. If the facility is located on a site that contains
clay, the facility would probably use on-site clay as the low-
permeability layer in the cover. If a facility is not located on
a site that contains clay, but is located near an off-site source
of clay, the facility would probably use off-site clay as the low-
permeability layer in the cover. A synthetic membrane would be
used as a low-permeability layer instead of clay when the cost for
materials, transportation, and installation of a synthetic
membrane is cheaper than the cost for materials, transportation,
and placement of off-site clay.
(3) Drainage layer with tiles to promote drainage of the final cover.
If a synthetic membrane is used in the final cover, the drainage
layer should be composed of sand. A gravel layer could puncture
1-2
-------
_
?9476.00-6
the syntnetic membrane. If only clay is used in the final cover,
either sand or gravel would be suitable for the drainage layer.
Three types of tile can be used in the drainage layer: PVC,
concrete, or vitrified clay.
(4) Topsoil which is used to support vegetation.
(5) Revegetation which provides ground cover to minimize soil erosion.
Revegetation consists of seeding, fertilizing, and mulching.
The RCRA regulations do not specify thicknesses for the sand, gravel, and
soil layers in the final cover. Recommended minimum thicknesses are presented
in Table 7-1.
7.2 UNIT COSTS
This section presents the unit costs for final cover and revegetation. All
final cover and revegetation costs are third party costs.
7.2.1 Native Soil for Slooe and Fill
Native soi" is used to bring the site to grade and establish a foundation
for the remaining cover layers. It was assumed that the shape of the cove"
foundation formed Dy the native soil is a pyramid with a three percent slope or
each side of the pyramid. This shape will promote maximum drainage of the cover
and prevent ponding. If the volume of soil needed for slope and fill is
unknown, the following equation should be used to give an approximation of the
volume of native soil needed for slope and fill:
_w
0.03 w2 (1 - 3)
where: V = volume (yd3)
w = the width of area to be capped (yd)
1 = the length of area to be capped (yd)

*9476.00-6
Tne unit cost for native scil for slope and fill consists of costs for exca-
vation of the soil with a dozer, placement and spreading of the excavated soil
with a grading scraper, and compaction of the placed soil with a sheepsfoot
roller. The excavation costs for native soil vary depending on the charac-
teristics of the soil to be excavated. Native soil unit costs are presented for
three different types of soil: soil with sand and gravel characteristics, soil
with common earth characteristics, and soil with clay characteristics. These
unit costs and a typical unit cost are summarized in Table 7-2. The individual
unit costs based on various equipment and soil factors are presented in Figures
7-1 through 7-3.
When soils are excavated and handled they increase in volume, or swell,
because of an increase in voids (air space). Compaction factors are used to
account for this material swelling when determining the volume of in-place soil
required. Table 7-3 shows the compaction factors for soil materials. The com-
paction factor is added to one and multiplied by the soil material unit cost.
For example, the typical native soil unit cost, including the compaction factor,
is: 55.77/yd3 x 1.25 = S7.21/yc3.
7.2.2 On-Site Clay
Table 7-1 presents a minimum thickness for on-site clay for determining the
volume of clay required in the final cover if volume is not specified in the
closure plan. The thickness shown in Table 7-1 would comply with the RCRA regu-
lations for a landfill cover.
The unit cost for on-site clay consists of costs for excavation of the clay
with a dozer, placement and spreading of the excavated clay with a grading
scraper, and compaction with a sheepsfoot roller. A range of on-site clay unit
costs and a typical on-site clay unit cost are summarized in Table 7-4. Figure
7-4 presents individual on-site clay unit costs based on different equipment
factors. Table 7-3 shows the recommended compaction factor for on-site clay.
(See the "Native Soil" section for an explanation of compaction factors.)
As the clay cap is being installed, each lift should be tested for moisture
content and density before proceeding to the next lift. Lifts are typically 6

to 8 inches thick (0.17 - 0.22 yd). For final cover areas < 5 acres, two
samples per lift are recommended. For final cover areas >_ 5 acres, three
samples per lift are recommended. The unit cost for clay testing is
S230/sample. This includes testing for moisture content, permeability, proctor
compaction, and labor.
7.2.3 Off-Site Clay
Table 7-1 presents a minimum thickness for off-site clay for determining the
volume of clay required in the final cover if a volume is not specified in the
closure plan. The thickness shown in Table 7-1 would comply with the RCRA regu-
lations for a landfill cover.
The unit cost for off-site clay consists of costs for purchase of the clay,
delivery to the land disposal facility, spreading the dumped clay with a dozer,
and compaction with a sheepsfoot roller. The purchase price for off-site clay
that is suitable for a hazardous waste land disposal facility cover is variable.
Clay costs can range from $4.75 to $14.50 per cubic yard depending on the pro-
perties of the clay and the amount of processing needed to make the clay
suitable for a land disposal facility cover. One source cited a purchase cost
of $4.75 per cubic yard for a suitable clay located in the northeast U.S. wnich
needed minimal processing. Another source cited a purchase cost of S12 to $1^
per cubic yard for a Georgia clay which required some processing to derive the
necessary properties to make it suitable for a land disposal cover. We assume a
typical cost to be $4.75 per cubic yard. Table 7-5 presents a list of delivery
unit costs for a range of distances. A range of off-site unit costs and a typi-
cal off-site clay unit cost are summarized in Table 7-6. Figure 7-5 presents
individual off-site clay unit costs based on various haul distances and equip-
ment factors. Table 7-3 shows the compaction factor for off -site clay. (See
the "Native Soil" section for an explanation of compaction factors.)
As the clay cap is being installed, each lift should be tested for moisture
content and density before proceeding to the next lift. Lifts are typically 6
to 8 inches thick (0.17 - 0.22 yd). For final cover areas <5 acres, two samples
per lift are recommended. For final cover areas _> 5 acres, three samples per
lift are recommended. The unit cost for clay testing is $230/sample. This
includes testing for moisture content, permeability, proctor compaction, and
labor.

7.2.4 Synthetic Membrane
A 30-mil synthetic membrane is the minimum thickness synthetic membrane
recommended which would comply with the RCRA regulations for a landfill cover.
The most typical type of 30-mi1 synthetic membrane used in a final cover is
polyvinyl chloride (PVC).
The unit cost for a synthetic membrane consists of costs for purchase, de-
livery, and installation. Installation includes rollout and spreading,
anchoring, and field seaming. Table 7-7 gives both a range of unit costs for
purchase, delivery, and installation and a typical unit cost for a 30-mil
synthetic membrane.
Prior to adding the remaining layers of the final cover, the synthetic
membrane should be visually inspected for punctures and the field seaming should
be tested by a different contractor than the contractor who installed the
membrane. A typical cost for this activity is 25 percent of the total membrane
cost.
7.2.5 Gravel
Table 7-1 presents a minimum thickness for a gravel drainage layer for
determining the volume of gravel required in the final cover if a drainage layer
volume is not specified in the closure plan. The thickness shown in Table 7-1
would comply with the RCRA regulations for a landfill cover.
The unit cost for gravel consists of costs for purchase of the gravel, de-
livery to the land disposal facility, spreading the dumped gravel with a dozer,
and compaction with a sheepsfoot roller. A range of gravel unit costs and a
typical gravel unit cost are summarized in Table 7-8. Figure 7-6 presents indi-
vidual gravel unit costs based on various haul distances and equipment factors.
Table 7-3 shows the compaction factor for gravel. (See the "Native Soil" sec-
tion for an explanation of compaction factors.)

Table 7-1 presents a minimum thickness for a sand drainage layer for
determining the volume of sand required in the final cover if a drainage layer
volume is not specified in the closure plan. The thickness shown in Table 7-1
would comply with RCRA regulations for a landfill cover.
The unit cost for sand consists of costs for purchase of the sand, delivery
to the land disposal facility, spreading the dumped sand with a dozer, and com-
paction with a riding vibrating roller. A range of sand unit costs and a typ-
ical sand unit cost are summarized in Table 7-9. Figure 7-7 presents individual
sand unit costs based on various haul distances and equipment factors. Table
7-3 shows the compaction factor for sand. (See the "Native Soil" section for an
explanation of compaction factors.)
7.2.7 Drainage Tile
Drainage tiles are placed in the sand or gravel drainage layer to collect
precipitation that infiltrates the cover. Drainage tiles are placed end-to-end
around the perimeter of the drainage layer.
The unit cost for drainage tile consist of the tile cost (including delivery
and excavating a trench in which to p^ace the tile), backfilling, and compac-
tion. Unit costs for three types of tile are presented: ?VC, vitrified clay,
and concrete. PVC unit costs and a typical drainage tile unit cost are sum-
marized in Table 7-10. The unit cost for the three types of tile are presented
in Figure 7-8.
7.2.8 Geotextile Filter Fabric
A geotextile filter fabric cost is incurred for a Part 264 landfill cover.
Trie geotextile filter fabric is placed on top of the drainage layer to prevent
clogging of the drainage tiles.
The unit cost for a geotextile filter fabric consists of purchase, delivery,
and installation costs. Table 7-11 lists both a range of unit costs for

7.2.9 Topsoil
Table 7-1 presents a minimum thickness for a topsoil layer for determining
the volume of topsoil required in the final cover if a topsoil volume is not
specified in the closure plan. The thickness shown in Table 7-1 would comply
with the RCRA regulations for a landfill cover.
The unit cost for topsoil consists of costs for purchase of the topsoil,
delivery to the land disposal facility, spreading the dumped topsoil with a
dozer, and compaction with a sheepsfoot roller. A range of topsoil unit costs
and a typical topsoil unit cost are summarized in Table 7-12. Figure 7-9 pre-
sents topsoil unit costs based on various haul distances and equipment factors.
Table 7-3 shows the compaction factor for topsoil. (See the "Native Soil" sec-
tion for an explanation of compaction factors.)
7.2.10 Crushed Stone
In arid regions of the country crushed stone nay be Deferred to vegetation
for controlling erosion. Crushed stone is preferred over sand because it is not
easily dispersed by wind and will not wash away if there is a rainfall event.
If crushed stone is selected instead of vegetation, the topsoil layer would be
omitted. Table 7-1 presents a minimum thickness for a crushed stone layer for
determining the volume of stone required in the final cover if a stone volume is
not specified in the closure plan. The thickness shown in Table 7-1 would
comply with the RCRA regulations for a landfill cover.
The unit cost for crushed stone consists of costs for purchase of the stone,
delivery to the land disposal facility, spreading the dumped stone with a dozer,
and compaction with a sheepsfoot roller. A range of crushed stone unit costs
and a typical crushed stone unit cost are summarized in Table 7-13. Figure 7-10
presents individual crushed stone unit costs based on various haul distances and
equipment factors. Table 7-3 shows the compaction factor for crushed stone.

7.2.11 Revegetation
The cost for revegetation includes costs for soil preparation and grading,
which consists of raking the topsoil layer; seeding at 261 pounds of seed per
acre; fertilizing at 968 pounds of fertilizer per acre, liming at 0.5 to 2.5
tons per acre, and mulching with a one inch deep layer of oat straw. A range of
seeding unit costs and a typical revegetation unit cost are summarized in Table
7-14. If revegetation is unlikely to be successful because the facility is
located in an extremely arid climate, a layer of material such as gravel could
be used to protect the cover and prevent v;ind dispersal of finer materials.
7.2.12 Mobilization/Demobi1ization
In addition to the unit costs for final cover and/or revegetation, a cost
for mobilization/demobilization of heavy equipment should be included. A range
of modi 1ization/demobilization costs and tyoical costs for final cover and re-
vecetation ere shown in Table 7-15.

CERTIFICATION OF CLOSURE AND POST-CLOSURE
Sections 264.115 and 265.115 of 40 CFR require certification by both the
TSDF owner or operator and an independent registered professional engineer (or
an independent qualified soil scientist for land treatment) when closure is
completed. This helps ensure that the facility is closed in accordance with the
specifications of the closure plan. Similarly, Sections 264.120 and 265.120 of
40 CFR require a certification, signed by the TSDF owner or operator and an
independent registered professional engineer, that post-closure care was per-
formed in accordance with the approved post-closure plan. The registered pro-
fessional engineer or soil" scientist may be eitner employed by a consulting firm
or operating independently in their own business.
Some facility owner/operators may not close all facility components at the
end of the facility's operating life, because parts of tne facility (i.e., lane-
fill cells, tanks, or other-process units) may have been closed at .various times
over a period of years prior to final closure. ~ne closures of parts of a fa-
cility prior to final closure are called partial closures. The RCRA regulations
recuire that partial closures be certified for waste piles, surface impound-
ments, landfill;, and lane t"eatmer,t units, -'ertial closures cf tanks, incin-
erators, or containers, however, GO not need to oe certified. Certification of
tne partial closure c* waste piles, surface impounaments, landfills, and land
treatment is to be performec wnen the partial closure is complete. This is
because it would be very difficult for an independent registered professional
engineer to verify, at the time of final closure, that all partial closures were
performed in accordance with an approved closure plan. Therefore, this section
contains unit cost guidance for certification of both partial and final clo-
sures.
A review of closure cost estimates has shown that many facility
owner/operators estimate the cost for certification of closure as a lump sum
cost (e.g., S2000). Another approach to estimating certification costs is to
base them on the professional engineer's time spent during the closure period.
8-1
-------
Poi icy
#9476.00-6 "
The latter method provides a more detailed cost estimate and is used in this
guidance document.
The labor rate ranges for personnel involved in closure and post-closure
certification are presented in the "Labor Categories and Rates" chapter of this
volume. Their typical labor rates are summarized in Table 8-1. All of the
labor rates reflect the cost of having the work performed by a third party. The
following sections contain methodologies for estimating costs for certification
of partial closures, final closure, and post-closure.
8.1 CERTIFICATION OF PARTIAL CLOSURES
The time requirements for personnel involved in certifying partial closures
will vary considerably, depending on the process unit that is being closed. The
recommendations presented in this section are for frequency of inspections and
estimates of the hours necessary for each inspection. They should be used only
if no information on the number of inspections is provided in the closure plan.
Table 8-2 contains the estimated personnel time requirements for certification
of partial closures.
The independent registered professional engineer or soil scientist will
likely conduct one to three visits per week for every week of the closure
period. The time needed per visit would vary with the complexity of the closure
activities; a reasonable range would be four to six hours per visit. This would
include time for both inspection of closure activities and preparation of a
brief status report on the facility. If the partial closure period lasts less
than a week, at least one visit from the P.E. or soil scientist should be
expected. The time needed per visit would vary with the complexity of the clo-
sure activities; a reasonable range would be four to six hours per visit
(including status report). In addition to the time spent inspecting the closure
activities, the professional engineer will require time to conduct a review of
the closure plan drawings, and specifications before partial closure activities
begin. It will also be necessary to prepare final documentation at the comple-

tion of the partial closure period certifying that the waste management unit has
'••een closed in accordance with specifications in the approved closure plan. The
time needed to review the closure plan is estimated at four hours, and four
hours is recommended to prepare final documentation.
The time requirements for the clerical person are for report typing and
recordkeeping. Clerical time would need to be included if the P.E. or soil
scientist is operating independently in his or her own single-person business.
Clerical time would be included in the hourly rate of a P.E. or soil scientist
who is an employee of a larger consulting firm. We estimate that two to four
hours of clerical time per week will be necessary for each partial closure.
8.2 CERTIFICATION OF FINAL CLOSURE
The lump sum certification costs in closure cost estimates we have reviewed
ranged from less than one percent to ten percent of the total closure cost. Trie
most comnoh value was approximately three oercent of the total closure cost. If
information on time retirements is not provides in the closure plan, we esti-
mate that the incec-enaent registered professional engineer or soil scientist
v."' 11 v'sit the facility approximately one to three times per week for four to
e~,cnt nou^s per visit curino eacn week of tne clos'j-e perioc. Th~s time esti-
mate includes travel to and from the site, insoection time, and time to draft a
short status report of the closure activities at tne facility. The frequency
and duration of the visits are dependent on the complexity and extent of the
closure activities, and the degree to which contamination is present at the
facility. A minimum of three visits from the P.E. c-* soil scientist should be
expected to certify final facility closure. In addition to the time spent
inspecting the closure activities, the professional engineer will require time
to conduct a review of the closure plan drawings, and specifications before
final closure activities begin. It will also be necessary to prepare final
documentation at the completion of the closure period certifying that the faci-
lity has been closed in accordance witn specifications in the approved closure
plan. The time needed to review the closure plan is estimated at eight hours
and four hours is recommended to prepare final documentation.

The clerical time required for recordkeeping, reporting, and accounting
responsibilities in association with the certification process is estimated to
be two to four hours per week for every week of closure. As with clerical time
for partial closure certification, it does not need to be included if the P.E.
or soil scientist is an employee of a consulting firm that is larger than a
single-person business. A summary of the estimated personnel time requirements
for certification of final closure is presented in Table 8-2.
8.3 CERTIFICATION OF POST-CLOSURE
The cost for certification of post-closure will be calculated in a similar
manner to that for the certification of final closure but will allow greater
time intervals between inspections. If information on time requirements is not
provided in the post-closure plan, we estimate that an independent registered
professional engineer will visit the facility twice a year for a minimum of four
hours for each visit. This time estimate includes travel to and from the site,
inspection time, and time to draft a short report on the status of the facil-
ity. In addition to the time spent inspecting the post-closure activities, the
professional engineer will reauire time to conduct a review of the post-closure
plan and specifications before post-closure activities begin. It will also be
necessary to prepare final documentation at the completion of the post-closure
period certifying that the waste management unit has been managed in accordance
with specifications in the approved post-closure plan. The time needed to
review the post-closure plan is estimated at four hours, and four hours is
recommended to prepare final documentation.
The clerical time required for recordkeeping, reporting, and accounting
responsibilities in association with the certification process Is estimated to
be four hours per visit. Clerical time does not need to be included if the P.E.
is an employee of a consulting firm that is larger than a single-person busi-
ness. Table 8-2 presents estimated personnel time requirements for cer-
tification of post-closure.

SECTION 9
LABOR CATEGORIES AND RATES
This chapter presents third-party personnel and subcontracted labor rates
used for both closure and post-closure activities. The descriptions of the
necessary personnel and estimates of their labor rates are presented as separate
subsections for closure and for post-closure care.
9.1 CLOSURE LABOR CATEGORIES AND RATES
Closure is assumed to be under the di"ection of an architectural/engineering
firm, and all closure activities will be performed by third-party personnel as
required "in the RCRA regulations. Descriptions of these personnel are provided
below. Costs ror ce"tein sits work activities (e.g., final cove" placement) are
based on unit costs (e.g., S/cubic yard of toosoil) which include labor, materi-
als, transportation, anc equipment. A complete description of these activities
and associated unit cost estimates can be found in the chaste" of thns volume
entitled "Final Cove" and Revegetation."
Tne following pe"scnriel w:" 1 D= required curing tne closure oe"ioc:
e Consulting Enginee": supervision and planning of all closure
acti vi ties
• Field Technician: inspections, monitoring, and sample collection
• Clerical: recordkeeping and reporting
• Equipment Operator: inventory handling and disposal
• Laborer: equipment and facility decontamination, repairs
e Draftsperson: preparation of isogram plan
• Process Operator: operation of incinerators, filter presses, and on-
site treatment
• Land Surveying Team: plat surveying activities
9-1
-------
o Attorney: submission of survey plat to local zoning authority
Labor rate estimates for these personnel are presented in Table 9-1. A
range of annual base salaries was estimated along with a typical base salary for
all of these personnel except the land surveying team and the attorney, whose
services would be subcontracted out to private firms. Fringe benefits and the
engineering firm's overhead were added to the base salaries of engineering firm
personnel. These figures were then divided by annual person-hours (2080 hours
per year) to arrive at the dollar-per-hour figures in the table.
Fringe benefits are usually estimated at 25 to 50 percent of the direct
labor costs. This includes such things as pensions, holidays and vacations,
sick leave, health and life insurance, disability insurance, social security,
and unemployment taxes. The engineering firm's overhead or general works
expense is usually estimated at 50 to 100 percent of the direct operating and
labor costs. This includes such service functions as supervision of personnel,
maintenance, security, accounting end ourchssing, as well as fixed and variable
costs on buildings and property in general use (e.g., offices, cafete-ias,
roads, parKinc lots, etc.).
Tnird-oarty laoore-s and equipment ooercto-s are assumed to be employed by £
construction firm c" s^te wo-k cont-acto-. Tne third-party process coe-cto'" is
assumed to be employe'c by a site clean-up contractor. Tnei1" do" 1 a'-oe^-nou^

benefits are assumed to be 25 percent of the labor costs. The subcontractor's
overhead and profit is assumed to be 45 percent. This fee is added to labor
costs which include fringe to arrive at the charged rates shown in the table.
9.2 POST-CLOSURE LABOR CATEGOIRES AND RATES
During the post-closure period, contracted labor will be used to provide
post-closure care and maintenance. Descriptions of personnel and fees charged
by an engineering firm to conduct these activities are presented in Table 9-2.

fringe benefits, overhead, and profit were added and the resulting dollar-per-
hour fee was derived. The engineering firm would subcontract to a local
construction firm to obtain the services of laborer and to a site clean-up
contractor to hire a process operator. In turn, a fee (profit) would be added
by the engineering firm to the dollar-per-hour cost for the laborer or process
operator. An attorney submits the waste record to the local land authority and
puts the notice in the deed to the property (§§264.119/265.119). Such legal
services would be subcontracted out to a private law firm.

CHAPTER 10
CLOSURE AND POST-CLOSURE INDIRECT COSTS
In addition to the direct costs of closure or post-closure such as inven-
tory disposal, decontamination, final cover, groundwater monitoring, and main-
tenance, certain indirect costs are also incurred. Indirect costs, or fees as
they are often called, are related to the design, construction, and testing of a
system or facility. These costs are usually not explicitly included in the
capital cost estimate, but are necessary to estimate the actual cost of a func-
tional system or facility. The following sections describe each of the indirect
costs and their application to preparing third party closure and post-closure
cost estimates.
10.1 APPLICABILITY OF INDIRECT COSTS
Fees are freauently expressed as percentages of the direct capital cost
estimate (i.e., equipment and material costs, installation labor costs, etc.).
-The type and range of fees vary on the basis of tne technology or construction
activity unaert3ken enc the project's complexity and scale.
It should be notea that a project bid prepared by a- general contractor is
usually structured differently than that suggested in this guidance document.
For instance, it is common for general contractors or subcontractors to include
an allowance for overhead and profit in the amount charged for each yard of
concrete or each hour of construction labor estimated. In some cases even
direct costs such as equipment mobilization/demobilization are included in the
material or labor unit cost bid amount. Furthermore, contractors may include an
allowance for contingencies in their bid price, rather than list this item
separately. In cases of high risk, however, contractors are likely to agree to
perfomi only certain duties for the bid price and insist on a "cost-plus" clause
to cover any items not specifically included in the bid.
10-1
-------
£9476.00-6
For the purpose of this document, the method of estimating direct and
indirect costs separately was selected. In this manner, the labor and material
cost components necessary to complete a specific task can be estimated directly
and are isolated from those expenses related to project management, scale and
complexity, and uncertainity. Estimates of these indirect costs are made
separately to account for the project's uniqueness and are added to the direct
costs to derive a final budget amount. Therefore, no allowance for engineering
and supervision, general contractor's overhead and profit, or contingency was
included in the unit costs presented i '\ this volume. The material and labor
unit costs listed were estimated using subcontractors, and include overhead and
profit on their labor, equipment, and materials used to complete each specified
task.
In evaluating a third party closure or post-closure cost estimate, the
reviewer should determine which items (if any) were estimated on the basis of a
contractor's project bid. Costs estimated by a contractor are likely to include
overnead and profit and a contingency but may not be listed separately in the
total bid p-ice. In these cases, no additional costs for th-e contractor's
overnead and profit or contingency should be estimated. On the other hand, if
the facility owne^/ooerator prepared the cost estimate without obtaining any
contractors' bids (or the reviewer is preparing a seoarate estimate using the
worksheets in this guidance document), tnen an allowance for a contractor's
ove-nead and profit and a contingency on tne total cost of tie project shc-lc oe
estimated separately as an indirect cost. The inclusion of an indirect cost for
engineering and supervision may also be appropriate and is discussed in the
following section of this chapter.
10.2 ENGINEERING AND SUPERVISION FEE
Facility closure following an approved closure plan will require little, if
any, additional engineering from an engineering firm. The approved closure plan
should already have sufficient architectural and engineering plans, drawings,
and specifications to properly close the facility. Costs for minor design modi-
10-2
-------
POMCV
#9476.00-6 "
fications requiring an architect or engineer are included in the contingency
fee, which is discussed later in this chapter. Closure administration, there-
fore, will likely be the responsibility of a general contractor who will sched-
ule and coordinate the site work, hire appropriate subcontractors, and
supervise, in conjunction with an independent professional engineer, all closure
activities.
In cases in which the facility owner/operator has hired an engineering firm
to coordinate closure or post-closure, the engineering firm will add their fee
(including profit) to those closure or post-closure activities under their
direction and management. This fee, which is referred to as engineering and
supervision, is often billed as a percentage of the direct capital cost estimate
for closure or post-closure care. Engineering fees typically include the costs
associated with engineering design, drafting, construction and cost-estimation,
field expense for construction supervision, home office expense (overhead), and
project administration. This fee usually ranges from five to twenty percent of
the direct capital costs of the project.
The fee charged depends on project scale (or size) and complexity. Sm=ll
projects (in terms of job cost), projects which reauire considerable field
supe-vision, projects with high degrees of uncertainty or risk, or projects
which present unusual site conditions will result in higher engineering and
supervision fees. In general, the percentage of the direct capital cost used to
calculate this fee usually decreases slightly as the direct capital cost of the
project increases. For example, projects less than $100,000 will result in fees
of ten to fifteen percent, while high total project costs (i.e., in excess of
one million dollars) will result in lower percentage fees, usually less than
eight percent.
Facilities intending to hire an engineering firm to oversee closure or post-
closure activities with existing, approved plans should expect a fee at the low
end of the range (e.g., 5%) to cover supervisory and administrative expenses
only. However, facilities which have not completed a closure (or post-closure)
plan or, on the basis of EPA review will require substantial modifications to
their existing plans, should include a fee of ten to fifteen percent of the clo-
10-3
-------
uWtk foncy u'
£9476.00-6
sure and post-closure costs for engineering. In these cases, the engineering
and supervisory fee should not be considered optional, because an engineering
firm will need to prepare new (or revised) closure and post-closure documents.
10.3 CONTRACTOR'S FEE
When a general contractor coordinates construction and closure activities it
will add overhead and profit as a percentage of the closure cost. The general
contractor's profit for construction projects is tyoically estimated at ten per-
cent of the direct costs. The contractors overhead expense, however, is quite
variable and dependent on job scale and location, competition, labor and eauip-
ment availability, and liability considerations. Tne range of the general
contractor's overhead for construction projects is five to twenty percent of the
direct costs (15-30% when profit is addec), but its fee may rise to as high as
fifty percent (including oro'it) with closure contracts.
Only "arely woulc a genera! contractor be hired to acminister post-closure
activities. It is mere likely for ar enaineering firm to manaae the post-
closure care and ni'-e subcor,tra:tors to pe^for-r certain maintenance activities
:cve" maintenance, erosion carnage reoci^. etc.) during the pcst-closjre
Dc""OG.
10.4 CONTINGENCY FEE
A contingency is added to cost estimates to compensate for errors of
omission, particularly in the conceptual stage of the cost estimate, and for
unforseeable circumstances. The failure to include items, generally minor, but
cumulatively significant may account for approximately ten percent of the fixed
capital investment during the conceptual stage of estimation. Unforseen cir-
cumstances include such things as storms, floods, fires, unanticipated price
changes, unproductive labor, strikes, and design modifications and are covered
by the contingency fee.
10-4
-------
OSWER Policy Directiv
#9476.00-6 "
The contingency fee varies from two to thirty percent of the direct plus
indirect capital cost of closure or post-closure. The contingency is highest in
the early, conceptual stage of project planning and decreases as plans become
more finalized, with firm cost estimates. These fees may vary as follows:
• conceptual stage 10 - 30%
• drawings, but incomplete 5 - 15%
• final plans, with bids 2 - 3%
t
Exceptions to this general scheme are alteration and repair projects, where
a twenty percent contingency is recommended even in the final design stages, and
projects with a high degree of risk, such as closure activities, where higher
contingency fees are allocated to cover unexpected site conditions, con-
tamination, or changes in the closure plan.
Closure and post-closure plans should be considered at the conceptual
planning stage even if detailed plans, specifications, and drawings have been
prepared. This is due to the high degree of risk and uncertainty associated
with many facility closures. Consequently, the contingency fee should vary from
ten to thirty percent depending on the complexity of the closure and post-
closure activities and the length of time needed to complete these activities.
Table 10-1 presents typical closure and post-closure contingency fees for
use on the summary worksheets if information on these fees in not provided in
the closure or post-closure plan. They reflect both the complexity of the clo-
sure and post-closure activities and the relative lengths of time needed for
closure. The contingency fees in Table 10-1 are for facilities at which there
is no existing soil contamination. Contingency fees at sites with known soil
contamination can be as high as 200 percent.

A.2 LABOR AND MATERIALS INDEXES BY REGION
An important element of the closure and post-closure cost estimates is the
selection of accurate unit costs for the variety of site work and labor activi-
ties performed. The unit costs (and prices) developed for this document repre-
sent average costs and prices in major cities of the United States for materials
and services required for site work under normal site conditions. For many
construction projects, however, adverse or unusual site conditions are encoun-
tered. This is particularly evident in hazardous waste facility construction,
closure, and post-closure. Unit costs for such closure activities as inventory
disposal, excavation of contaminated soils, clay cover construction, and topsoil
placement vary considerably among closure cost estimates submitted by TSDF
owners and operators.
Variations in unit costs are primarily the result of regional differences in
material and labor rates and whether required materials are available on-site or
must be purchased and transported from an off-site source. Other factors which
affect unit and project costs significantly are weather, season of year, site
topography, soil type", job size, safety requirements, site accessibility, travel
time, equipment availability, building code and permit requirements, availabil-
ity of utilities, and presence of a skilled labor force. Local or regional
shortages of construction materials can also significantly influence urit
costs. It is possible, however, to apply construction cost indexes for various
cities to incorporate labor and material cost characteristics inherent to speci-
fic locations. For instance, variations in wage rates, labor efficiency, union
restrictions, and material prices will result in regional differences that can
be factored into a cost estimate by using appropriate construction indexes. An
example of city indexes for each EPA Regional Office is provided in Table A-3.
The city indexes, prepared from data for 162 major U.S. and Canadian cities by
R.S. Means for both materials and installation, are based on the 30 major city
average of 100 and represent the cost relationship as of July 1, 1985. Table
A-3 also reports a factor, derived from the "total" index, that can be used to
quickly index a cost estimate to a particular EPA Regional Office. This is
accomplished by multiplying the closure or post-closure cost estimate from the
summary worksheet (prior to aoplying the engineering fee, contractor's overhead
and profit, and contingency factor) by the Regional city cost factor listed in
the table.

All of the costs reported in this unit cost guidance document are 1986
costs. In subsequent years the various unit costs will increase or decrease,
changing the resultant total closure and post-closure costs. During the active
life of the facility, the owner or operator must adjust the closure and post-
closure cost estimates for inflation within 60 days prior to the anniversary
date of the establishment of their financial instruments (within 30 days after
the close of the firm's fiscal year for firms using the financial test or cor-
porate guarantee). This adjustment may be made by recalculating the costs of
closure or post-closure in current dollars (a very time-consuming process), or
by using an inflation factor derived from the most recent Implicit Price
Deflator for Gross National Product published by the U.S. Department of Commerce
in its Survey of Current Business. The inflation factor is the result of
dividing the latest published annual Deflator by the Deflator for the previous
year. For example, assume that the latest closure cost estimate is $50,000; the
latest published annual Deflator is 111.7 (1985); and the annual 'Deflator for
the previous year (1984) is 108.1. Dividing 111.7 by 108.1 gives the inflation
factor, 1.03. Multiplying $50,000 by 1.03 gives a result of $51,500, the
adjusted closure cost estimate.
To update a specific unit cost used in the calculation of closure or post-
closure costs, the Builders' Construction Cost Indexes are recommended and
available in quarterly "cost roundup" issues of the journal Engineering News
Record (ENR). The. two general-purpose cost indexes we suggest using are the
"ENR 20-Cities: Construction Cost," or the "Means: Construction Cost." Their
January 1986 values are 392 and 356, respectively. By using these indexes, unit
costs can be updated quarterly, biannually, or annually. To update a unit cost,
look up the value corresponding to the new date (e.g., January 1986) in either
cost index, divide the new value by the 1985 value and multiply the resulting
factor by the original unit cost to arrive at a new (updated) unit cost.

1.1 INTRODUCTION
This is Volume IV of the Guidance Manual: Cost Estimates for Closure and
Post-Closure Plans (Subparts G and H). It contains the documentation for the
unit costs presented in Volume III. The purpose of this documentation i's to:
• present information on the source(s) used for each unit cost;
• provide examples of any computations performed in developing a
unit cost; and
• describe any assumptions made i.n developing the unit costs.
All costs are in 1986 dollars. They were developed based on the regulatory
requirement that closure and post-closure cost estimates reflect the costs of a
third party performing all closure/post-closure activities.
Following this introduction, Volume IV is divided into nine chapters that
correspond to the unit cost chapters in Volume III. These chapters are:
• Monitoring and Testing
t Inspection and Maintenance
• Inventory and Residual Management
• Equipment and Facility Decontamination
• Demolition and Excavation
• Final Cover and Revegetation
• Certification of Closure and Post-Closure
• Labor Categories and Rates
• Closure and Post-Closure Indirect Costs

Mobilization/Demobilization of -ieavy Equipment
• Means provides data on man-hours needed for the mobilization/demobil-
ization of a limited number of equipment sizes, and the resulting costs.
In order to obtain costs for other sizes of equioment, equations were
derived which relate the number of man-hours needed for a piece of
equipment as a function of equipment size. The equation is in the
following form:
Y = mX + b, where
Y = time needed for mobil/demobi1ization (hrs)
X = equipment capacity (yd3)
m = slope
b = y-intercept
Values for m and b were derived for each equipment tyoe by solving
simultaneous equations using the data in Means Site Work Cost Data 1986,
p. 41. 'The resulting general equation was then used to determine the
nunber of man-hours needed for any equipment size. To calculate the
mobilization/demobilization cost, this number of man-hours was
multiplied by $76/hr (Source: R.S. Means, Means Site Work Cost Data
1986, p. xx). This process is illustrated by the following example
for backhoe mobi1i zation/demobi1i zation.

5.2.3 Tank Removal
• Tank Surface Area
The tank removal unit costs are based on tank surface area.
When only tank capacity in gallons is known assumptions must
be made to determine the tank surface area. The smallest sur-
face area for a cylindrical tank will be achieved when the
width and the height are approximately equal. Typcially the
height is sligntly larger or equal to the diameter of a
cylindrical taik. The following example shows how the surface
area was calculated for a 500, 1000, 2500, 5000, and 10,000
gallon tank.
Example - Tank Surface Area Calculation for a 500 Gallon Tank
500 gallon x — = 66.84 ft3 (volume)

Assuming that d£h, then d or h can be found by:

If the tank is assumed to be 4 ft in diameter, then height is:
h = 85ai . a^n = 5>32 or 5>5feet

The surface area of a 500 gallon tank is then found using:
Surface area = 2 ir r2 + 2 Tf rh
Surface area = 2 TT (2)2 + 2 it (2)(5.5) = 94 ft2

#9476.00-6
Means Site Work 1986 includes fertilizer and mulch with
the seed cost for hydraulic spreading. Tractor A
spreading only includes the seed cost. To obtain the ™
hydraulic spreading seeding cost without fertilizer and
mulch, subtracted the seed, fertilizer, and mulch cost
with overhead ..and profit from the total unit cost. This
difference is the labor cost for hydraulic spreading.
Added the labor cost with over head and profit to the
tractor spreading seed cost with overhead and profit.
Example for slope mix:
tractor spreader
seed only = S7.50/MSF x 1.10 (overhead + profit) =
S8.25/MSF
hydraulic spreader with seed, fertilizer, + mulch
total cost with overhead
and profit (OP) = S32/MSF

Mulch
• Assume mulch spread using a tractor spreader
• Means Site Work 1986 does not list a unit cost for trac-
tor spreading straw but lists a cost for spreading with
a large power mulcher. Means does list a unit cost for
spreading other mulches with a tractor spreader. To
estimate the unit cost for spreading oat straw used the
materials cost for oat straw and the labor and equipment
cost for tractor spreading humus peat and peat moss.
