Subject:
Proposal for Ash Remediation Project
New Hanover County WASTEC Facility
3002 Highway 421 North
Wilmington, North Carolina
Withers & Ravenel Proposal No. 0308064
Dear Mr. Marlow:
We appreciate your consideration of Withers & Ravenel to conduct the environmental
remediation project described in the New Hanover County Department of
Environmental Management request for proposals dated July 1, 2008. Withers &
Ravenel has the relevant experience and expertise to undertake work of this nature,
and would welcome the opportunity to assist you with this project. Our proposal
includes detailed descriptions of pertinent background information, the proposed
scope of services, New Hanover County responsibilities, project schedule, fees for
services, and authorization procedures.
Background Information
Information regarding the project was provided in the County's July 1, 2008 request
for proposals, and during guided site visits conducted on July 7 and 8, 2008.
Incinerator ash generated at the subject site inadvertently entered the stormwater
drainage system, which discharges into a wooded area on the eastern side of the
WASTEC facility property. New Hanover County reported the incident to the North
Carolina Department of Environment and Natural Resources (NCDENR), Division of
Waste Management - Solid Waste Section, and that agency directed the County to
conduct an assessment to determine if the discharge had adversely affected
underlying groundwater quality. The County contracted Withers & Ravenel to conduct
the groundwater assessment, the results of which are contained in a report dated
May 5, 2008, and submitted the report to the Solid Waste Section.
Results of the assessment indicated that groundwater beneath the area where ash
can be observed on the ground surface exhibited Cadmium concentrations that
exceed the North Carolina groundwater standard for Cadmium established in 15A
NCAC 2L. This caused the Solid Waste Section to issue a Notice of Violation dated

June 9, 2008, which instructed that in order to attain compliance with 15A NCAC 13B
.0509(6) and .0509(9), the County should take the following actions:
1. Implement corrective action by confirming the full extent of the ash release
2. Remove the full extent of the ash release from the site
3. Conduct additional assessment to completely delineate the groundwater
contaminant plume
4. Continue monitoring groundwater conditions on a semi-annual basis until
contaminant concentrations are reported below the 15A NCAC 2L standard
The New Hanover County Department of Environmental Management subsequently
conducted an in-house assessment of the horizontal and vertical extent of affected
soils in the discharge area. Through this assessment, the County determined that
the extent of affected soils is approximately 100 by 250 feet in area, and 18-inches in
depth. The area of affected soils is presently marked with flagging.
Through their assessment, the County has met the requirements of item 1 referenced
above. The County now needs assistance from a qualified environmental consultant
to meet the requirements of remaining items 2, 3 and 4.
Proposed Scope ofSeNices
If awarded the contract for this project, Withers & Ravenel will serve as the turnkey
project coordinator to complete the scope of services described in Attachment A of
the July 1, 2008 request for proposals. We will conduct the scope of services in
accordance with current NCDENR Solid Waste Section policies, applicable OSHA
regulations, and EPA Region IV well installation and sampling procedures.
The project will consist of three consecutive tasks. Task 1 will consist of constructing
a temporary road into the affected area, removing trees and vegetation from the
area, excavating the top 18-inches of soil within the affected area, and transporting
the excavated soil to an on-site staging area that will be lined with 6-mil plastic
sheeting. Task 2 will consist of the installation, development and sampling of two
additional shallow (Type II) groundwater monitoring wells, and a deep telescoping
(Type iiI) monitoring well, testing the samples for Cadmium content, and preparing a
report that documents the results. Task 3 will involve preparation of a groundwater
monitoring plan, and implementing the monitoring plan on a semi-annual basis for a
period of two years. Additional information regarding the scope of services to be
performed within each task is provided in the following paragraphs.

Task 1: Removal of Ash
Withers & Ravenel will subcontract the services of A&D Environmental Services, Inc.
(A&D), a qualified North Carolina environmental remediation contractor that we have
worked with on similar types of projects in the past, to perform the site clearing and
soil removal aspects of this task. Withers & Ravenel will provide an on-site
representative to oversee and document the activities of our subcontractor. A&D will
prepare a site specific Health & Safety Plan and all personnel assigned to work at the
site will be 4o-hour OSHA HAZWOPER trained and medically monitored. A&D will
mobilize the following resources to the site to conduct this task.

(1) Track Loader
(2) Chainsaws
(200 ft) Silt Fence

Personnel Protective E ui ment
Ex endables
6-mil Pol eth lene Sheetin
Road Fabric
ABC Stone
# Stone
Prior to beginning invasive activities in the affected area, A&D will install silt fencing
to the east and down slope of the area for sedimentation and erosion control. They
will then clear and grade an access way and place road bed fabric along the route.
ABC stone and/or #57 stone will be place on the fabric and compacted with a
trackhoe to form the access. Disturbed area on both sides of the access road will be
graded, seeded and covered with straw as an erosion control measure.
A&D will then use the equipment and manpower shown above to clear and grub the
affected area. Stumps and root mats will be shaken or handled in a fashion to
remove as much soil as possible within the affected area. A&D will then transport
the removed trees, stumps and root mats to a NCDENR Solid Waste Section
permitted Land Clearing and Inert Debris landfill or processing/disposal facility. It is
our understanding that A&D will be permitted to use the scales at the WASTEC
facility so we can keep track of the amount of land clearing debris that is removed
from the site.
A&D will then prepare the designated staging area to receive excavated soil and ash
by placing 6-mil polyethylene sheeting on the ground surface. Hay bales will be
placed under the outer edges of the sheeting for stability and runoff control. The top
18-inches of soil within the affected area will then be excavated and transported up
the access way to the staging area. The stockpiled soils will be covered and secured
with 6-mil polyethylene sheeting at the end of each work day and during rain events
that may occur during the work day.
The County estimates that approximately 1,400 cubic yards of soil will need to be
removed from the affected area, which is approximately equal to a 1.5 foot thickness
of soil over a 100 by 250 foot area. The access road and silt fencing will remain in
Proposal for Ash Remediation Project

Page 4 of8
place after the affected soils have been removed and stockpiled. However, the
excavated area will not be backfilled or seeded. Rather, the area will be allowed to
re-vegetate naturally. After A&D has completed its work and has left the site, the
stockpiled soil will be managed and disposed by the County.
Task 2: Monitoring Wells
Following completion of soil removal within the affected area, Withers & Ravenel will
return to the site to install the three monitoring wells specified in Attachment A of
the July 1, 2008 request for proposals. Our services to complete this task will include
the following:
. Mobilization of trained Withers & Ravenel and subcontractor drilling
personnel and appropriate sampling equipment to the site.
. Advancement of three soil borings for collection of soil samples for
classification purposes, and to accommodate installation of groundwater
monitoring wells.
. Installation of two 2-inch inner diameter (lD) Type II PVC monitoring wells,
each with a lS-foot length of o.ol-inch slot PVC screen. For cost estimating
purposes and as directed in the request for proposals, we have assumed that
the total depth of each well will be 20 feet. Because these wells and the
existing wells will be used for groundwater monitoring purposes for the next
two years (see Task 3), our proposed cost includes installation of
aboveground steel protective covers for each of the new and existing wells.
The wells will be constructed in accordance with lSA NCAC 2C by a North
Carolina Certified Well Driller (Quantex, Inc. Certification # 3106) and each
wellhead will be secured with a locking cap.
. Installation of one telescoping type (Type Ill) PVC monitoring well to provide a
means of assessing groundwater quality at greater depth and defining the
vertical extent of Cadmium in groundwater. Type III monitoring well
constructions consist of an outer larger diameter PVC casing that is grouted
into place, and an inner smaller diameter casing that extends through the
bottom of the outer casing to intercept a lower water bearing strata. The outer
casing of the Type III monitoring well will consist of 4-inch ID Schedule 40 PVC
pipe that will extend through the surficial aquifer and ten feet into the fine-
grained sediments of the Pee Dee Formation, which we expect to encounter at
a depth of approximately 3S feet based on our previous drilling experience in
the vicinity of the site. The outer casing will then be tremie-grouted into
place. After the grout has been allowed to cure for at least 24 hours, the
boring will be extended below the bottom of the outer casing and 10 feet
further into the Pee Dee sediments using the rotary wash drilling method. At
this depth, a five foot length of 1-inch 10 Schedule 40 PVC well screen
attached to an appropriate length of 1-inch 10 Schedule 40 PVC riser pipe will

be inserted into the boring. Filter sand will be installed around the screened
section and a bentonite seal will be installed above the filter sand and into
the outer casing. The remaining annular space between the inner and outer
well casings will be filled with bentonite-cement grout by the tremie method.
The top of Type III well will be secured with a locking water-tight cap, and a
above ground steel protective cover will surround the well head.
. Purging of potentially stagnant groundwater from each monitoring well using
low-flow sampling equipment (Grunfos<ID Rediflow submersible pump,
peristaltic pump, or bladder pump), including dedicated Teflon<ID tubing
which will remain in the wells for use during future sampling events. We will
measure and record the pH, specific conductivity, temperature and turbidity
of the water produced and the water level within the well at regular intervals
during the purging process. We will use a Horiba U-10 Water Quality Checker
connected to a flow cell or equivalent for field measurement of water quality
parameters.
. Collection of groundwater samples after removal of a volume of water no less
than three times that standing in the well prior to purging, and after water
quality parameters have stabilized. The samples will be decanted directly
from the Teflon<ID tubing into laboratory prepared containers that contain
appropriate amounts of the required preservative. The containers will be
labeled with appropriate information and stored in a cooler with ice until
delivered to the laboratory.
. Completion of Chain-of-Custody documentation and delivery of the samples
to our subcontractor laboratory Environmental Chemists, Inc. (Envirochem) in
Wilmington for analysis of Cadmium using EPA Method 6010, or other
NCDENR Solid Waste Section approved method if necessary. Envirochem is a
NCDENR Certified Laboratory (Number 94) and is one of Withers & Ravenel's
approved subcontractor laboratories.
. Determination of new monitoring well locations by tape measure to .:': 1.0 feet,
and measurement of relative top of well casing elevations using a builder's
level to .:': 0.01 vertical feet. Horizontal coordinates of the new wells and
elevations of the ground surface and top of well casings will be determined
with respect to those of existing wells which were surveyed previously.
. Preparation of boring logs, well completion reports, a site map showing well
locations and water-table gradient, summary tables of well construction
information and laboratory analytical results, and a written report that
describes and documents our assessment activities, and our conclusions and
recommendations. We will prepare a draft report for review by the New
Hanover County Department of Environmental Management, and a final report
following receipt of comments. The final report will be prepared for the
exclusive use of New Hanover County.

Task III: MonitorinR ProRram
Withers & Ravenel will develop a written Groundwater Monitoring Plan that meets the
requirements of 15A NCAC 13B .0504(1)(g)(iV) and .051O(d). The plan will serve as a
guidance document that describes the monitoring well network, and that defines
groundwater sampling and analysis procedures and methods that will be followed
throughout the duration of the groundwater monitoring program.
The monitoring program will include collection of groundwater samples from the six
monitoring wells on a semi:annual basis for a duration of two years. Each
groundwater sample will be analyzed for Cadmium using EPA Method 6010, or other
NCDENR Solid Waste Section approved method if necessary. Withers & Ravenel will
prepare a summary report following receipt of laboratory analysis results for each
sampling event. Each report will describe in detail the field sampling methods used
and the analytical results. For each event, we will prepare a draft summary report for
review by the New Hanover County Department of Environmental Management, and a
final report following receipt of comments. The final report will be prepared for the
exclusive use of New Hanover County.
New Hanover County Responsibilities
As previously stated, the New Hanover County Department of Environmental
Management conducted an in-house assessment of affected soils and has
determined their extent to the satisfaction of the NCDENR Solid Waste Section.
Therefore, responsibility for determination of the volume of affected soil to be
removed rests with the County.
Representatives of the County have stated to Withers & Ravenel that the incinerator
ash generated at the WASTEC facility is periodically tested for the hazardous waste
toxicity characteristic according to the Toxicity Characteristic Leaching Procedure,
and that results of these tests show that the ash consistently meets criteria for
classification as non.hazardous waste. Accordingly, and in compliance with 15A
NCAC 13B .0509(6), the ash is used as daily cover at the New Hanover County
Landfill, located to the north of the WASTEC facility on US Highway 421. We
understand that the County has informed the NCDENR Solid Waste Section that the
affected soils generated during this project will be disposed at the County landfill,
where it will also be used as daily cover.
We also understand that the County will be responsible for the following activities
that are important to the timely and successful completion of this project, and
achieving compliance with NCDENR Solid Waste Section regulations:
. Clearly marking with flagging or other denotation the area where trees and
vegetation are to be removed, and the area where an 18-inch thickness of
affected soils are to be removed.

. Providing and identifying heavy equipment staging and supply storage areas.
. Providing and identifying stockpile area for affected soils.
. Providing a non-potable water source for rinsing off equipment, if necessary.
. Any testing of the excavated and stockpiled soil that may be required prior to
transport to the disposal facility.
. Any confirmation testing of soils remaining within the excavation area.
. Loading and transportation of affected soils to the disposal facility.
. Disposal of 6-mil plastic sheeting and hay bales remaining in the stockpile
area following removal of the affected soils from the site.
Project Schedule
We anticipate that A&D will be prepared to begin work on Task I within two to three
weeks of Withers & Ravenel's receipt of authorization to proceed from the County.
A&D estimates that Task I can be completed within 5 to 7 workdays.
Withers & Ravenel will begin Task 2 within two weeks of completion of Task 1. We
expect that installation and development of the three additional monitoring wells
will require 3 workdays, and that purging, sampling and surveying of the three wells
can be completed in one day. Laboratory analysis of the samples typically requires
two weeks and we will prepare our draft report for Task 2 within one week of receipt
of the analysis results.
Preparation of the Groundwater Monitoring Plan described in Task 3 will begin
following submittal of the final report for Task 2. We expect that the draft plan will
be ready for the County's review within one week thereafter. Collection of semi.
annual groundwater samples will require one to two days to complete for each event.
Laboratory analysis of the samples will typically require two weeks and we will
prepare our draft summary report for each of the four semi-annual events within one
week of receipt of the analysis results.
