POST-CONSTRUCTION MAINTENANCE PLAN
SOIL AND SURFACE WATER REMEDIATION
KOPPERS COMPANY, INC. SUPERFUND SITE
MORRISVILLE, NORTH CAROLINA
1.0 INTRODUCTION
This Post-Construction Maintenance Plan (Plan) describes the anticipated activities that
will be performed to maintain and monitor the integrity of the soil and surface water
remediation, and ancillary components of the Koppers Company, Inc. Superfund Site
(Site). These ancillary components include fences and gates, drainage ditches, the
geogrid/geotextile system. and site vegetation. This Plan serves only to address the
maintenance requirements relative to the activities conducted during the remedial action
(RA) construction.
Past operations at the site involved wood preservation through pressure injection of
pentachlorophenol. As a result. soil and sediments in the Fire Pond area and sediment in
Medlin Pond were impacted with pentachlorophenol and dioxins. As part of the RA
Construction Activities, the Fire Pond and Medlin Pond were dewatered, the water treated
using carbon filtration, and discharged in accordance with a NPDES permit into the
drainage ditches located on site. The pond sediments were covered with geogrid and
nonwoven geotextile, backfilled with clean fill, and the two ponds seeded in accordance
with the project specifications.
The Plan describes the activities that will be implemented to maintain the items listed
below after final acceptance of the subject areas has occurred.
• Geogrid/geotextile system;
• Backfill in Fire and Medlin Pond areas;
• Soil excavation areas;
• Fence and gates;

2.0 FIRST YEAR MAINTENANCE ITEMS
This section of the Plan addresses items that will be addressed specifically during the first
year following the completion of construction. During this first year. the Fire Pond,
Medlin Pond. soil excavation areas. and ancillary components will be maintained by
Beazer in accordance with specifications provided in Appendix A. The overall site layout
is depicted on Figure 2-1. This includes soil cover maintenance, fence maintenance,
maintenance of the sedimentation control filter berm, corrective action associated with
settlement, and repairs associated with erosion.
Items that will be addressed specifically during the first year include final acceptance of
the grass cover, removal of silt fence, and, as required, cleaning out of the filter berrn.
2.1 FINAL ACCEPTANCE OF GRASS COVER
After the first foll growing season that permanent seeding is applied, Beazer will evaluate
the grass cover, to assess final acceptance. Final acceptance will be based on the
requirements of Section 02260: SEEDING, as presented in Appendix A. Beazer will
require reseeding of any and all areas that are not satisfactory as detem1ined by the
speci ti cations.
Grass cutting is anticipated to be perforrned two to three times the first year. Cutting will
be done using riding or walk behind mowers depending on the site area and softness of
the ground.
2.2 REMO\' AL OF TEMPORARY EROSION AND SEDIMENT CONTROLS
Any silt fence installed during construction will be removed after the final acceptance of
the grass cover. Some or all of the silt fence may be removed prior to final acceptance if
it is determined that portions of the silt fence are no longer needed due to an adequate
vegetative cover uphill of these temporary erosion and sediment controls.

3.0 MAINTENANCE ACTIVITIES
The Fire Pond, Medlin Pond. soil excavation areas, and ancillary components will be
inspected and maintained throughout the post-construction maintenance period.
The soil excavation areas have been backfilled with soiL compacted, graded, and seeded
to blend with adjacent topography. Maintenance of these areas is expected to consist of
maintaining a vegetative cover. and repairing of settled or eroded areas.
The Fire and Medlin Pond areas which were covered during site remediation activities are
expected to continue settling as pond sediments beneath the soil cover drain and
consolidate over time. The primary maintenance activities are expected to be grass
cutting and filling in depressions resulting from localized settlement.
3.1 SITE INSPECTIONS
3.1.1 Site Features
The following features of the site will be examined during maintenance inspections:
• Fire and Medlin Pond Areas: Visual evidence of significant
differential settlement and ponding of rainwater, and erosion.
• Security Devices: Fencing, gates, and locks used to prevent
unauthorized access to the site will be inspected for physical damage
and/or removal.
• Surface Water Control Structures: Drainage ditches will be
inspected for erosion or obstruction; and, the filter berm will also be
inspected for sediment accumulation.
• Site Vegetation: Surface vegetation will be checked for continuity.

3.1.2 Inspection Frequency
All site features listed in Section 3.1.1 will be inspected monthly for the first year after
final acceptance. semi-annually for the following four years and annually thereafter.
Beazer will assess the need for continued measurements if data indicates conditions have
not significantly changed through three consecutive inspections and may petition to
decrease inspection frequency.
3.1.3 Inspection Records and Reports
The result of each inspection will be summarized in a report and submitted to US EPA
and NCDEHNR. Inspection records and reports will document, but not be limited to, the
following items:
• The condition of all security devices, including fences and gates.
• The adequacy of vegetative growth, seeding, and/or repairs required on the
soil cover.
• The location of visible geogrid/geotextile, including any evidence of possible
damage to the system or evidence of significant differential settlement.
• The condition of surface water drainage ditches, including amount of
accumulated sediment.
Appendix B provides a checklist to be used during regular inspections. The checklist will
be submitted after each inspection. A concise report will also be prepared to document
the reasons for and nature of any repair undertaken in accordance with this Plan.
3.2 SECURITY FENCE SYSTEM
3.2.1 Description of Security System
Security at the site consists of a seven-foot high chain-link fence that has been installed
around the Fire Pond area. All gates in the fence will remain locked while the site is
unattended.

3.2.2 Maintenance of Security Fence
Because of normal wear and potential vandalism. periodic maintenance may be required
to provide continued integrity and effectiveness of the security fence. Fence repair and
replacement will be performed on an as-needed basis and will be initiated within 21 days
of identification. Other items of the security system that may require maintenance or
replacement include locks and chains.
3.3 POND COVER SYSTEM
Corrective measures to the pond cover system will be required if inspections reveal
significant erosion. surface displacements, sediment exposure, or damage that will impact
the integrity of the cover system. The system will be repaired as needed in a manner that
provides a long-term solution to such damage. Settled areas that may require repair will
be backfilled and regraded to uniform grades and slopes. If relatively minor differential
settlement occurs, soil cover may be placed on the affected area to bring it back to grade.
The location and degree of settlement where repairs are made will be documented in the
inspection report.
3.4 SURFACE \VATER DRAINAGE
3.4.1 Drainage Ditch Maintenance
Where accumulation of materials significantly hinders flow of runoff through the ditches
or culverts, excessive sediment or debris will be removed.
Corrective measures will be required if inspections reveal that drainage ditches are no
longer functioning properly. This may be evidenced by ponding of surface water. severe
erosion, or accumulation of sediment or debris in drainage ditches. Affected portions of
the ditch will be repaired to the intent of the original specifications.
3.4.2 Responses to Severe Storm Erosion
Portions of the site which may experience substantial erosion as a result of severe storms
include the soil cover and drainage ditches. The following responses may be employed in
the event that such erosion is detected.

Soils: Sand bags or other devices will be positioned to divert and disperse
the flow of runoff responsible for erosion until the damaged areas are
repaired. If required to control sedimentation from eroded areas along the
perimeter. silt fence or other appropriate devices will be installed.
Drainage Ditches: Sand bags or other devices will be positioned at
eroding areas to prevent further erosion and to contain runoff within the
ditches until the damaged areas are repaired.
3.4.3 Sedimentation Control Structures
Inspections will assess the condition of vegetation and indications of erosive conditions
along the filter berm area and the drainage ditch leading into the filter berm. Erosion of,
or other damage to, these areas will be evaluated. In addition, the berm will be inspected
for obstruction or other damage.

The Fire Pond and portions of the Medlin Pond areas will be vegetated with grasses.
Corrective measures will be required if inspections reveal excessive erosion, vegetative
overgro\\1h and/or damage that will impact the integrity of the cover system. Eroded
areas will require removal of the affected loose soil followed by replacement and
regrading to the original contour. Any areas lacking vegetation will be reseeded and re-
fertilized as needed in accordance with Section 02260: SEEDING, as presented in
Appendix A, to maintain adequate cover.
3.5.1 Mowing Schedule
It is anticipated that the soil cover vegetation will be mowed three times a year depending
on weather conditions at the site. When mowing, the grass should not be cut to less than
three inches in height. After mowing, an inspection of the soil cover will be performed
and any irregularities found will be corrected.

3.5.2 Reseeding, Mulching and Fertilizing
As a result of routine soil cover maintenance activities of cover soil vegetation, it is
anticipated that periodic reseeding and mulching may be required to maintain appropriate
vegetation throughout the maintenance period. The frequency of reseeding and mulching
will depend on the occurrence of soil surface repair and vegetation coverage. The
seeding materials used during the maintenance period will meet the necessary
requirements of Section 02260: SEEDING.
If economically advantageous, seeding and mulching may be perfom1ed by a hydro-
seeding unit. If smaller areas require reseeding and mulching, the process may be
performed manually. A balanced fertilizer and straw mulch may be used. If appropriate,
fertilizer and lime will be applied during seeding.
3.6 MEDLIN \VETLAND AREA
The Medlin wetland area will be maintained in accordance with criteria established for
the Seagondollar property wetland. The maintenance activities are detailed under
separate cover.

2. Temporary Seeding: The Contractor shall roughen the ground surface to a
depth of one inch prior to temporary seeding. Temporary seed shall be
mulched.
3. Permanent Seeding: If required based on the soil test results, lime,
fertilizer, and organic soil amendments shall be incorporated into the soil
to a minimum depth of two inches during seedbed preparation with field
cultivators, heavy-duty harrows, heavy disk or other approved equipment.
If applicable, the fertilizer and lime may be applied with a hydroseed.
Planting Seed
1. General: Prior to seeding, any previously prepared seedbed areas
compacted or damaged by interim rains, traffic, or other cause, shall be
reworked to restore the ground condition previously specified. Seed shall
be planted at the rate specified herein.
2. Method: Seed planting shall be accomplished by:
a. Hydroseeding: The Contractor shall accomplish seeding, and
fertilizing, by hydroseed application. Seed and fertilizer with
other soil conditions in the amount per acre designated, shall be
combined with water to provide a slurry, and hydraulic
application shall be performed in such manner that the liquid
carrier will uniformly distribute the material over the entire

area to be seeded at rates not less than indicated herein. No
following compaction shall be done. The seeded area shall be
watered after seeding and the soil moistened to a depth of two
to four inches.
b. Manual Seeding: Small areas (approximately one-half acre or
smaller) may be seeded and mulched manually or as directed
by the Construction Manager.
Mulching: Mulching shall be performed by the Contractor on the same day as
planting seed.
1. Applying Mulch: Straw mulch shall be spread uniformly in a continuous
blanket over the seeded areas, using three tons of material per acre. The
mulch shall be spread in such a manner as to prevent bunching. Mulching
shall be started on the windward side of relatively flat areas or on the
upper part of a steep slope and continued uniformly until the area is
covered.
2. Securing Mulch: Immediately following the spreading of the mulch, paper
fiber mulch overspray shall be sprayed over straw or hay mulch. when
sprayed over the mulch the fibers form an absorbent cover, allowing
percolation of water to the underlying soil. The recycled paper shall be
applied at a minimum rate of 800 pounds per acre or mon: if
recommended by the manufacturer. The mulch shall be mixed with water
so as to produce a homogeneous slurry which shall be applied under
pressure by hydraulic seeding equipment. The mix shall be constantly
agitated during application to keep the ingredients thoroughly mixed.
Alternatively, the material shall be anchored securely into the soil a
minimum of three inches by means ofa mulch anchoring machine
equipped with large coulter-type discs spaced on approximate eight-inch
centers. Edges of the discs shall be dull to prevent cutting of the
mulching, and equipment operation shall be such as to embed the mulch to
the required depth. In areas where equipment cannot be used, mulch shall
be secured by shallow covering of each area or by embedding with
approved hand methods, including straight-bladed spade with dulled edge.
Erosion Control Material: The surface of ditches and slopes to receive soil
erosion control material shall be finished to a smooth and even condition with
all debris, roots, stones and lumps raked out and removed.

I. Erosion Control Blanket: Soil erosion control blanket shall be installed
where indicated on the Drawings. Straw mulch shall not be used with soil
erosion control blanket.
a. General: Soil erosion control blanket shall be unrolled and
placed with the netting on top. Apply wire staples vertically
through the netting and blanket into the ground, keeping
netting taut against anchor staples. Erosion control blanket
placement shall be accomplished without damage to the
installed material or distortion of established grades.
b. Ditches and Slopes: Erosion control blanket shall be laid in
accordance with the manufacturer's recommendations.
2. Silt Fence: Silt Fence shall be installed where indicated on the Drawings.
A six inch deep trench shall be dug just outside the posts for the full length
of the silt fence. Set the studded "T" posts a maximum of ten feet on
center. Incline the posts toward the runoff source at angle of not more than
20 degrees from vertical. Drive the posts into the ground so that no more
than 3 feet protrude above the ground. Attach the fabric to the posts, and
place the fabric into the trench and backfill and compact the soil. All
splice joints shall overlap a minimum of 18 inches.
Protection and Cleanup: After seeding and mulching operations have been
completed, barricades and approved warning signs shall be erected by the
Contractor as required to provide protection against traffic and trespass.
Excess material from seeding and mulching operations, and all debris, shall be
cleaned up and properly disposed off site.
Maintenance
I. Maintenance operations shall begin immediately after seeding and shall
continue throughout the construction time.
a. Seeded Areas: Keep seed moist continually for proper
germination and water thereafter as necessary to prevent drying
out or burning. Reseed areas not showing a prompt catch of
grass, correct depressions and irregularities and reseed; repeat
until a complete coverage is obtained.

2. At conclusion of constrnction, the Construction Manager will make an
inspection of the lawn work to determine condition of acceptance. The
Contractor shall make such additional repairs as required by the
Construction Manager at no expense to Beazer.
3. Beazer herein retains the right to require that the Contractor reseed any
and all areas where a satisfactory stand of grass does not exist after the
first full grov.ing season after the final permanent seeding has been
applied. A satisfactory stand of grass shall be defined as 90 percent
coverage of every five acre area having a three inch stand of grass as
determined by the step transect method or as otherwise defined by the
Construction Manager. The step transect method estimates the percentage
of vegetative cover using at least I 00 systematically located observation
points within the seeded area.

3.0 MEDICAL SURVEILLANCE
Personnel performing field work will be required to have a medical examination prior to
the initiation of intrusive field activities. Employees are given a baseline physical and
follow-up examinations either annually in accordance with OSHA ( employee having 30
days or more of exposure per year) or whenever they accumulate 30 days of exposure.
All subcontractor personnel performing intrusive field activities or repair and restoration
activities on site will be required to demonstrate that they participate in a medical
surveillance program in accordance with OSHA requirements.

4.0 HAZARD ASSESSMENT
An evaluation of conditions at the Site has been made to determine the potential effects
upon site personnel during the field activities. This qualitative evaluation is based on the
following:
• Nature of potential contaminants;
• Presence of potential contaminants at specific work areas;
• Levels of contamination:
• Potential for personnel and public exposure during various site
activities; and
• Effects of potential contaminants on human health.
The hazard associated with exposure varies directly with the amount of contamination to
which an individual is exposed and the length of exposure. Exposure potential is defined
as the probability of a worker or the public receiving harmful exposures. Site specific
information will be made to the firm responsible for post-construction maintenance from
Beazer.
4.1 CURRENT FIELD ACTIVITIES
4. l. l Project Personnel
Past operations at this site were in wood preservation through pressure injection of
pentachlorophenol. During initial operations, waste water from this process was
discharged to the on site Fire Pond. Drainage from the Fire Pond flowed into the nearby
Medlin Pond.
Past site data indicates that pentachlorphenol and dioxins were detected in the soil and
pond sediment. Remedial activities included soil removal and off-site incineration,
draining the ponds, covering the pond sediments with geogrid and non-woven geotextile
fabric, covering with clean fill, and seeding the two pond areas to facilitate drainage of
storm water.

The potential hazard for personnel performing post construction maintenance activities
is low. The primary activities are walking the remediated site and observing
construction features. However, a hazard may exist if damage to the cover system
occurs which causes personnel exposure to pond sediment. No soil disturbance
activities are planned during these activities. If needed for repair work, the use of
protective clothing and equipment, air monitoring, and standard procedures, will be used
to minimize personnel exposure.
4.1.2 Public
The post-construction maintenance activities will have no effect on potential public
exposure.

5.0 TRAINING
Project field personnel performing intrusive repair and restoration work will have
received 40 hours of training in accordance with OSHA 29 CFR 1910.120. In addition to
the 40 hours of off-site training, each employee must have received a minimum of three
days of on-the-job training under the supervision of a trained experienced supervisor.
The project personnel will review the I-ISP prior to working at the site.
Documentation of the training will be submitted to the Project Manager and will be
placed in the project files. The Site Health and Safety Officer (SHSO) and HSC will
document safety problems, changes in site conditions, monitoring results, or other safety-
related topics. Site visitors will be informed of the site hazards and emergency
procedures.

6.0 WORK AREAS
The field activities will not be confined to one contiguous area, but will be conducted
throughout the site area. An exclusion zone will be established for any intrusive
activities. Anyone entering the exclusion zone will be required to be trained and wear the
appropriate protective equipment.

7.0 PERSONNEL PROTECTIVE EQUIPMENT
Equipment for personnel protection will be based on USEPA levels of protection as
specified in the Standard Operating Safety Guides (USEPA, 1992). Protective equipment
will be compatible with and provide protection from the class of compounds known to be
on site and any additional compounds identified during the work. The protective
equipment will provide respiratory protection and skin and eye protection for personnel
operating as needed in the designated exclusion and contamination-reduction zones.
Protective equipment selection will also be based on task-specific conditions.
The following sections provide a description of the minimum protective equipment for
initial use based on task and location. The results of the air monitoring program
(Section 8.0) may require changes (upgrade/downgrade) in the protection required.
Potential changes could be more or less personnel protective equipment, depending upon
the type and concentration of contaminants detected.
Initially, all personnel in the Site work areas will be required to wear the following basic
work clothing:
• Work clothes;
• Work boots; and
• Eye protection.

8.0 RESPIRATORY PROTECTION PROGRAM
A respiratory protection program that meets OSHA Standard 29 CFR 1910.134 will be
implemented when and if respirators are required for this project. The training required
by OSHA covers maintenance and cleaning of respirators. Each individual will be
responsible for his or her own respirator.
Respirators will be stored in a clean, dry, sanitary area where they are protected against
mechanical damage, dust, heat, extreme cold, excessive moisture, or damage by chemical
contact.

9.0 HEAT/COLD STRESS
Heat stress is not expected to be a concern because extensive protective equipment is not
anticipated for inspection tasks. If maintenance or repair activities required the use of
protective equipment, employees wili be instructed as to the warning properties and
treatment for heat stress.
Due to the relatively mild climate and anticipated short-term duration of any maintenance
activities, cold-related problems are unlikely to occur during this project. If maintenance
activities must be performed in cold weather, employees will be instructed to dress
warmly and to avoid getting wet.

11.0 EMERGENCY RESPONSE
Emergency response procedures have been developed to cover extraordinary conditions
that may occur at the Site. If emergencies do arise, they are anticipated to most likely be
typical construction-site emergencies such as equipment fire and minor worker injury
(i.e., cuts, bruises). Complex situations involving uncontrolled hazardous materials are
very unlikely, bemuse site activities will not result in the disturbance of contaminated
material.
11. 1 GENERAL RESPONSE CONSIDERATIONS
Emergencies will be dealt with in a manner that minimizes the health and safety risk to
site personnel and the public. In the following paragraphs, it is assumed that the HSC is
not present on site and a qualified individual will be designated the SHSO.
The following pror,edures shall be implemented in the event of an emergency:
• First aid or other appropriate initial action will be administered by
those closest to the accident/event. This assistance will be coordinated
by the ranking individual on site and will be conducted in a manner so
that those rendering assistance are not placed in a situation of
unacceptable risk. The primary concern will be to avoid placing a
greater number of workers in jeopardy.
• Employees shall report all accidents and unusual events to the SHSO,
Project Manager and the HSC. The Project Manager will notify the
client Project Coordinator.
• The SHSO will be responsible for conducting the emergency response
in an efficient, rapid, and safe manner. The SHSO will decide if off-
site assistance and/or medical treatment are required and shall be
responsible for alerting off-site authorities and arranging for their
assistance.
• The SHSO will provide to the Project Manager an incident report
which includes the following:

a description of corrective actions implemented or other
resolution of the incident.
• All workers on site are responsible for conducting themselves in a
mature, calm manner in the event of an accident/unusual event. All
personnel must conduct themselves in a manner to avoid increasing
risk to themselves and to other workers.
11.2 RESPONSIBILITIES
The SHSO or a designated substitute shall have responsibility for directing response
activities in the event of an emergency. He/she will:
• Assess the situation,
• Determine required response measures,
• Notify appropriate response team,
• Detem1ine and direct on-site personnel during the emergency, and
• Contact and coordinate with government agencies.
He/she shall coordinate response activities with those of public agencies.
The SHSO shall be responsible for implementing the HSP emergency response
provisions for all personnel and visitors on site. The SHSO shall be responsible for
knowing what personnel are on site and where they are located.
11.3 NOTIFICATIONS
The following are client and public response agencies to be contacted and who may,
depending on the nature of the situation, assume authority for emergency response. In the
event of an emergency situation, site personnel shall lend necessary assistance to the
agency in charge.

I 1.5 ACCIDENTS AND NON-ROUTINE EVENTS
Several types of emergencies are outlined in the following subsections. These are not
intended to cover all potential situations, and the corresponding response procedures
should not be followed blindly. Every accident is a unique event that must be dealt with
by trained personnel working in a calm controlled manner. In the event of an
accident/unusual event, the prime consideration will be to provide the appropriate initial
response to assist those in jeopardy without placing additional personnel at an
unnecessary risk.
The vast majority of worker injuries on hazardous waste sites are non-chemical in nature.
The injuries tend to be sprains, rashes, and lacerations which, because of protective
equipment and site conditions. must be treated promptly. Follow-up care is extremely
important to assure that a minor injury or illness does not become aggravated by site
conditions. Employees shall be instructed to report all injuries and illnesses to the HSC.
If a person working in a contaminated area is physically injured, Red Cross first aid
procedures shall be followed. Depending on the severity of the injury, emergency
medical response may be sought. If the employee can be moved, he/she will be taken to
the edge of the work area where contaminated clothing will be removed and emergency
first aid administered. The worker will then be transported to a hospital, if required.
The SHSO shall inform the HSC and Project Manager of the injury/accident, and a
wTitten report detailing the accident, its causes, and any consequences shall be submitted
to the Project Coordinator within three working days of the incident.
11.6 CONTINGENCY PLAN
In the unlikely event that site evacuation is necessary, the SHSO will notify on-site
personnel verbally. The SHSO is also responsible for notifying the appropriate agencies.
The nearest telephone for emergency use will be in the Site vehicle. Telephones of
nearby residences and other businesses could be used in an emergency. The evacuation
route will be to a rendezvous point. The rendezvous point will be the Beazer Project
trailer.
