E. Impact Justification and Mitigation U
1. Avoidance and Minimization
1a. Specifically describe measures taken to avoid or minimize the proposed impacts in designing the project:
The utility corridor was designed to cross streams as close to perpendicular as possible with access points outside of buffer zones to allow a
maintenance corridor of 10 feet with stream buffers. At stream crossing areas, excavation will be limited to the width of the trench necessary for
replacement (less than 10 LF along channel at each crossing).
1b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques:
Access in streams will be limited to necessary operations. All stream work will be done in the dry using a pump around during construction. Temporary
stream crossings will be used for equipment during construction. Pump arounds will minimize land disturbance and utilize culverts when applicable to
reduce traffic disturbances. After construction, all disturbed stream banks and buffers will be planted in native herbaceous seed mixes and appropriate
woody species will be replanted to reestablish a woody buffer.

2. Compensatory Mitigation for Impacts to Waters of the U.S. or Waters of the State
2a. Does the project require Compensatory Mitigation for impacts to Waters of the U.S. or Waters of the State?
C Yes C No
2b. If this project DOES NOT require Compensatory Mitigation, explain why:
Permanent impacts to streams, and buffers are anticipated to be minimal and cause no more than minimal adverse effects on aquatic life, water quality, or buffer integrity.
F. Stormwater Management and Diffuse Flow Plan (required by DWR) C-)
1. Diffuse Flow Plan
1a. Does the project include or is it adjacent to protected riparian buffers identified within one of the NC Riparian Buffer Protection Rules?

Dear Mr. Sullivan,
I am pleased to submit a Nationwide Permit 12/13 Pre -Construction Notification (PCN) for the proposed
utility is High Temperature Hot Water (HTHW) Supply and Return Project for the Environmental
Protection Agency (EPA) in Research Triangle Park. The PCN is being submitted as a notification on behalf
of the Environmental Protection Agency (EPA) & National Institute of Environmental Health Sciences
(NIEHS) and the design engineers, RMF Engineering, Inc.
The HTHW line will serve the EPA campus buildings by connecting the central utility plant. Much of the
proposed utility will be constructed within an existing maintained utility easement. The existing easement
is approximately 115 feet wide with the proj ect along one side. To connect the supply line from the existing
easement to the EPA campus building, a portion of the project will be on a new alignment through the
forest. The new alignment through the forested area will be approximately 750 feet in length and require a
width of approximately 45 to 70 feet for construction, but after construction is complete the permanently
maintained width within buffer areas will be reduced to 10 feet. Please see the attached figures.
A site determination for streams and wetland was conducted with the US Army Corps of Engineers on
February 15, 2018. No wetlands were found within the proposed corridor, but three stream features subject
to Corps jurisdiction are present. The attached PCN package includes PCN Form, supporting figures, stream
data form, buffer No Practical Alternatives Application, and design plans. The project meets all conditions
of the NWP 12 and NWP 13 and their corresponding 401 General Certification GC 4133 and GC 4134.
Total stream impacts resulting from the proposed project are 238 LF of temporary impacts and 10 LF of
permanent impacts. Only Buffer Rule Approval is sought in writing. Within buffer Zone 1, temporary
impacts will be 15,595 SF and permanent impacts will be 1,200 SF. Within buffer Zone 2, temporary
impacts will be 7,960 SF and permanent impacts will be 800 SF. Permanent impacts to streams, and buffers
are anticipated to be minimal and cause no more than minimal adverse effects on aquatic life, water quality,
or buffer integrity. Please contact Matthew Boatwright at 919-941-9876 (matthew.boatwright(&rmf.com)
or George Lankford at 919-602-0127 (gklankford9l&gmail.com) if you need additional information or
have questions about the nature of the site.
Thank you for your prompt attention to this important project and please let me know if you have any
questions or require any additional information.
Sincerely,
George K Lankford, LLC

RE. ECM 1A High Temperature Hot Water Distribution System, EPA
Dear George Lankford.
The North Carolina Natural Heritage Program (NCNHP) appreciates the opportunity to provide
information about natural heritage resources for the project referenced above.
Based on the project area mapped with your request, a query of the NCNHP database, indicates
that there are no records for rare species, important natural communities, natural areas, and/or
conservation/managed areas within the proposed project boundary. Please note that although there
may be no documentation of natural heritage elements within the project boundary, it does not
imply or confirm their absence, the area may not have been surveyed. The results of this query
should not be substituted for field surveys where suitable habitat exists. In the event that rare
species are found within the project area, please contact the NCNHP so that we may update our
records.
The attached `Potential Occurrences' table summarizes rare species and natural communities that
have been documented within a one -mile radius of the property boundary. The proximity of these
records suggests that these natural heritage elements may potentially be present in the project area
if suitable habitat exists. Tables of natural areas and conservation/managed areas within a one -mile
radius of the project area, if any, are also included in this report.
If a Federally -listed species is found within the project area or is indicated within a one -mile radius of
the project area, the NCNHP recommends contacting the US Fish and Wildlife Service (USFWS) for
guidance. Contact information for USFWS offices in North Carolina is found here:
httr)s://www.fws.gov/offices/Directory/ListOffices.cfm?statecode=37.
Please note that natural heritage element data are maintained for the purposes of conservation
planning, project review, and scientific research, and are not intended for use as the primary criteria
for regulatory decisions. Information provided by the NCNHP database may not be published
without prior written notification to the NCNHP, and the NCNHP must be credited as an information
source in these publications. Maps of NCNHP data may not be redistributed without permission.
The NC Natural Heritage Program may follow this letter with additional correspondence if a
Dedicated Nature Preserve, Registered Heritage Area, Clean Water Management Trust Fund
easement, or Federally -listed species are documented near the project area.
If you have questions regarding the information provided in this letter or need additional assistance,
please contact Rodney A. Butler at rod nev.butlerWncdcr.gov or 919-707-8603.
Sincerely,
NC Natural Heritage Program

CLASSIFICATION: UNCLASSIFIED
Hey Matt,
Due to my current workload, I am not issuing standalone JDs unless the applicant has a justifiable need for expediting the
JD. If a permit is required for the proposed project under section 404 of the Clean Water Act, I would likely just issue the
PJD concurrently with the permit. I do not need to issue a PJD to begin the permitting process. Further, I can issue the
permit without issuing the PJD.
As stated in the email below, I have visited the site and concurred with the delineation. I assume that having me concur
with the delineation is sufficient in this case, as there were no isolated features that need an approved jurisdictional
determination to remove them. Therefore, you can move forward with planning the project knowing that the Corps has
agreed to the delineation.
Please feel free to contact me with any further questions.
Best,

Hey Matt,
I have reviewed the PJD application, and I agree that that mapping depicts the potentially jurisdictional waters of the U.S.
that I observed within the Review Area. However, it will take me some time to issue the JD as I have a considerable number
of permits and JDs to work through before getting to this one.
If you are planning to impact any of the potential waters of the U.S. with your project, please feel free to coordinate with me
to determine the most appropriate permitting approach. You do not need to have a PJD before we start this process. If you
submit a permit application to me, then it would bump your project up on my priority list.
Please let me know if you need any further assistance.
Thanks,
Ross

FINDING OF NO SIGNIFICANT IMPACT
National Environmental Policy Act Environmental Assessment for Implementation of Energy Savings
Performance and Conservation Measures at Research Triangle Park, NC
U.S. Environmental Protection Agency, Office of Administration and Resources Management
The United States Environmental Protection Agency (EPA) is proposing to implement a campus -
wide Energy Savings Performance Contract (ESPC) at its laboratory facility in Research Triangle Park
(RTP) located in Durham, NC: coordinates N 35.880111, W 78.873695. This ESPC, enabled through
the Department of Energy's established ESPC program, would entail major building system
upgrades and utility infrastructure replacements, ultimately resulting in large gains in energy
efficiency and operational reliability, while reducing the facility's environmental footprint. This
Environmental Assessment (EA) has been prepared to analyze the potential environmental
consequences associated with implementation of the following Energy Conservation Measures
(ECMs).
EPA proposes to construct a high temperature hot water (HTHW) supply and return pipeline to
connect the National Institute of Environmental Health Sciences (NIEHS) steam plant (Building 105)
to Building E on the EPA's campus. The action area is approximately4 acres with the HTHW pipeline
extending approximately 2,985 linear feet between the two buildings. The area between the two
buildings is an undisturbed, wooded 5G0 -year floodplain and contains two unnamed streams.
Ground disturbance would be required for this project with approximate dimensions of 2,985 feet
(length) by 2 feet (width) by 8 feet (depth).
In addition to the HTHW pipeline installation, this project would involve equipment replacements
within several buildings' heating ventilation and air conditioning (HVAC) units, boiler rooms, and
lighting systems; all replacements would occur within the interior portions of buildings that were
constructed between 1997 and 2000. None of these equipment replacements would result in
ground disturbance or exterior modifications to the buildings.
The EPA campus at RTP consists of over 1.2 million square feet of office, laboratory, computer, and
conference spaces housing 15 EPA program offices, including EPA's major center for air pollution
research and regulation. The project area would include the following buildings and parking areas
on the RTP campus: Building A and Annex, Building B, Building C, Building D, Building E, South
Parking Garage, North Parking Garage, High Bay Building (HBB), National Computer Center (NCC),
First Environments Early Learning Center (FEELC), and NIEHS Building 105 (Central Utility Plant).
In amordance with EPA's Regulations on implementation of National Environmental Policy Act
(NEPA) Procedures (40 Code of Federal Regulations [CFR] Part 6), an Environmental Assessment
(EA) was prepared pursuant to NEPA (42 United States Code [USC] §4321 et seq.), as amended, the
Council on Environmental Quality (CEQ) Regulations for Implementing the Procedural Provisions of
NEPA (40 CFR §§ 1500-1508). The purpose of this EA was to analyze the potential individual and
cumulative environmental impacts of the construction of the ECMs and to determine whether to
prepare an Environmental Impact Statement (EIS) orthis Finding of No Significant Impact (FONSI).

The Proposed Action, as described in the EA, will not result in any significant adverse impacts to
geology, topography, and sails; water resources and water quality; floodplain management;
terrestrial and aquatic environment; wetlands; threatened and endangered species; migratory
birds; bald and golden eagles; hazardous materials; socioeconomics; energy usage; traffic; or
historic and cultural resources. During the construction period, short-term minor impacts to
terrestrial environment, wetlands, migratory birds, bald eagles, and traffic are anticipated. All short-
term impacts require conditions to minimize and mitigate impacts to the proposed project site and
surrounding areas.
Mitigation measures for the Proposed Action pertain to the construction phase of the new HTHW
buried distribution pipeline and disposal of hazardous waste of lighting improvements; no
mitigation measures are necessary for operation of the HTHW buried distribution pipeline,
Laboratory HVAC Optimization, and Building ASteam System Optimization. These mitigation
measures pertain to impacts regulated at the federal level. EPA is responsible for obtaining and
maintaining any necessary permits at the local, county, and state level.
• Temporary sediment and erosion control devices, such as silt fencing, would be used,
inspected, and maintained throughout construction.
• Post -construction, all disturbed areas would be replanted with native, locally sourced grass
seed.
• Staging areas would be at least 100 -feet from the edges of the unnamed streams and
Discovery Lake.
• Equipment maintenance, such as fueling, would only occur within staging areas.
• Normal stream flow for the unnamed streams would be reestablished by re -constructing
stream depth and banks to the original conditions using engineered, natural -looking
methods.
• A walk-through of the trees marked for removal would occur to ensure bald eagle and other
migratory bird nests are not present prior to beginning construction activities.
• A visual inspection of the ASTs would be conducted before, during, and after nearby
trenching to check for and address any leaks. Leak detection systems would be monitored
during nearby trenching.
• Any hazardous wastes generated, such as depleted light ballasts, would be disposed of
according to EPA's existing hazardous material disposal procedures at RTP.
FINDINGS
Based upon the mitigation measures and information contained in the EA for the ECMs and in
accordance with EPA's Regulations on Implementation of NEPA Procedures, and Executive Orders
11988 (Floodplain Management), 11990 (Protection of Wetlands), and 12898 (Environmental
Justice), EPA has determined that the proposed actions would not have any significant impacts on

the quality of the natural and human environment. As a result of this FONSI, an EIS will not be
prepared.

MULCHING
CONSTRUCTION SPECIFICATIONS:
Select a material based on site and practice requirements, availability of material, and availability of labor
and equipment. Table 6.14a lists commonly used mulches and some alternatives.
Before mulching, complete the required grading, install sediment control practices, and prepare the
seedbed. Apply seed before mulching except in the following cases:
- Seed is applied as part of a hydroseeder slurry containing wood fiber mulch.
- A hydroseeder slurry is applied over straw.
Application of Organic Mulch:
Organic mulches are effective where they can be tacked securely to the surface. Materials and specifications
are given in Table 6.14a.
Spread mulch uniformly, by hand or with a mulch blower. When spreading straw mulch by hand, divide the
area to be mulched into sections of approximately 1,000 square feet and place 90 pounds of straw
(2 BALES) in each section to facilitate uniform distribution. After spreading mulch, no more than 25%
of the ground surface should be visible. In hydroseeding operations a green dye, added to the slurry, assures
a uniform application.
Anchoring Organic Mulch:
Straw mulch must be anchored immediately after spreading. The following methods of anchoring mulch
may be used:
Mulch anchoring tool --A tractor -drawn implement designed to punch mulch into the soil, a mulch anchoring
tool provides maximum erosion control with straw. A regular farm disk, weighted and set nearly straight,
may substitute, but will not do a job comparable to the mulch anchoring tool. The disk should not be sharp
enough to cut the straw. These methods are limited to slopes no steeper that 3:1, where equipment can
operate safely. Operate machinery on the contour.
Liquid mulch binders --Application of liquid mulch binders and tackifiers should be heaviest at the edges of
areas and at crests of ridges and banks, to resist wind. Binder should be applied uniformly to the rest of the
area. Binders may be applied after mulch is spread or may be sprayed into the mulch as it is being blown
onto the soil. Applying straw and binder together is the most effective method. Liquid binders include
asphalt and an array of commercially available synthetic binders.
Emulsified asphalt is the most commonly used mulch binder. Any type thin enough to be blown from spray
equipment is satisfactory. Asphalt is classified according to the time it takes to cure. Rapid setting (RS or
CRS designation) is formulated for curing in less than 24 hours, even during periods of high humidity; it is
best used in spring and fall. Medium setting (MS or CMS) is formulated for curing within 24 to 48 hours,
and slow setting (SS or CSS) is formulated for use during hot, dry weather, requiring 48 hours or more
curing time.
Apply asphalt at 0.10 gallon per square yard (10 gal/1000sq. ft.). Heavier applications cause straw to
"perch" over rills.
In traffic areas uncured asphalt can be picked up on shoes and cause damage to rugs, clothing etc. Use types
RS or CRS to minimize such problems.
Synthetic binders such as Petroset, Terratack, and Aerospray may be used, as recommended by the
manufacturer, to anchor mulch. These are expensive and therefore usually used in small areas or in
residential areas where asphalt may be a problem (Use of trade names does not constitute an endorsement).
Mulch nettings --Lightweight plastic, cotton, jute, wire, or paper nets may be stapled over the mulch
according to the manufacturer's recommendations.
Peg and twine --Because it is labor-intensive, this method is feasible only in small areas where other
methods cannot be used. Drive 8-10 inch wooden pegs to within 3 inches of the soil surface, every 4 ft in all
directions. Stakes may be driven before or after straw is spread. Secure mulch by stretching twine two or
more times around each peg. Twine may be tightened over the much by driving pegs further into the
ground.
Vegetation --Rye (rain) may be used to anchor mulch in fall plantings, and German millet in spring.
Broadcast at 151b%acre before applying mulch.
MAINTENANCE:
Inspect all mulches periodically, and after rainstorms to check for rill erosion, dislocation, or failure. Where
erosion is observed, apply additional mulch. If washout occurs, repair the slope grade, reseed, and reinstall
mulch. Continue inspections until vegetation is firmly established.

SEEDING
CONSTRUCTION SPECIFICATIONS:
Seedbed Preparation:
Install necessary mechanical erosion and sedimentation control practices before seeding, and complete
grading according to the approved plan.
Lime and fertilizer needs should be determined by soil tests. Soil testing is performed free of charge by the
North Carolina Department of Agriculture soil testing laboratory. Directions, sample cartons, and
information sheets are available through county Agricultural Extension offices or from NCDA. Because the
NCDA soil testing lab requires 1-6 weeks for sample turnaround, sampling must be planned well in
advance of final grading. Testing is also done by commercial laboratories.
When soil tests are not available, follow rates suggested on the individual specification sheet for the seeding
mix chosen.
Application rates usually fall into the following ranges:
- Ground agricultural limestone:
- Light -textured, sandy soils: 1-1 1/2 tons/acre
- Heavy -textured, clayey soils: 2-3 tons/acre
- Fertilizer:
- Grasses: 800-1200 Ib/acre of 10-10-10 (or the equivalent)
Apply lime and fertilizer evenly and incorporate into the top 4-6 inches of soil by disking or other suitable
means. Operate machinery on the contour. When using a hydroseeder, apply lime and fertilizer to a rough,
loose surface.
Roughen surfaces according to Surface Roughening.
Complete seedbed preparation by breaking up large clods and raking into a smooth, uniform surface (slopes
less than 3:1). Fill in or level depressions that can collect water. Broadcast seed into a freshly loosened
seedbed that has not been sealed by rainfall.
y111111]I1[e3
Seeding dates given in the seeding mixture specifications are designated as best or possible. Seedings
properly carried out within the best dates have a high probability of success. It is also possible to have
satisfactory establishment when seeding outside these dates. However, as you deviate from them, the
probability of failure increases rapidly. Seeding on the last date shown under possible may reduce
chances of success by 30-50%. Always take this into account in scheduling land -disturbing activities.
Use certified seed for permanent seeding whenever possible. Certified seed is inspected by the North
Carolina Crop Improvement Association. It meets published North Carolina Standards and should bear an
official Certified Seed label.

SEEDING (CONT.)
Labeling of non -certified seed is also required by law. Labels contain important information on seed purity,
Inoculate legume seed with the Rhizobium bacteria appropriate to the species of legume.
Apply seed uniformly with a cyclone seeder, drop -type spreader, drill, cultipacker seeder, or hydroseeder on
a firm, friable seedbed.
When using broadcast -seeding methods, subdivide the area into workable sections and determine the
amount of seed needed for each section. Apply one-half the seed while moving back and forth across the
area, making a uniform pattern; then apply the second half in the some way, but moving at right angles to
the first pass.
Cover broadcast seed by raking or chain dragging; then firm the surface with a roller or cultipacker to
provide good seed contact.
Mulch all plantings immediately after seeding.
Irrigation:
Moisture is essential for seed germination and seedling establishment. Supplemental irrigation can be very
helpful in assuring adequate stands in dry seasons or to speed development of full cover. It is a requirement
for fine turf establishment and should be used elsewhere when feasible. However, irrigation is rarely critical
for low -maintenance vegetation planted at the appropriate time of the year.
Water application rates must be carefully controlled to prevent runoff. Inadequate or excessive amounts of
water can be more harmful than no supplemental water.
MAINTENANCE:
Generally, a stand of vegetation cannot be determined to be fully established until soil cover has been
maintained for one full year from planting. Inspect seeded areas for failure and make necessary repairs and
reseedings within the same season, if possible.
Reseeding --If a stand has inadequate cover, reevaluate choice of plant materials and quantities of lime and
9 q � P
fertilizer. Reestablish the stand after seedbed preparation or over -seed the stand. Consider seeding
temporary, annual species if the time of year is not appropriate for permanent seeding.
If vegetation fails to grow, soil must be tested to determine if acidity or nutrient imbalance is responsible.

EROSION AND SEDIMENT CONTROL NOTES:
The contractor shall comply with the following requirements:
1. Equipment utilized during the construction activity on a site must be operated and maintained in such
a manner as to prevent the potential or actual pollution of the surface or ground waters. Fuels,
lubricants, coolants, and hydraulic fluids, or any other petroleum products, shall not be discharged on
to the ground or into surface waters. Spent fluids shall be disposed of in a manner so as not to
enter the waters, surface or ground, and in accordance with applicable state and federal disposal
regulations. Any spilled fluids shall be cleaned up to the extent practicable and disposed of in a
manner so as not to allow their entry into the waters, surface of the ground, storm sewers, or drains
on private or public (State) property.
2. Herbicide, pesticide, and fertilizer usage during the construction activity shall be restricted to those
materials approved by EPA and shall be used in accordance with label restrictions.
3. All wastes composed of construction materials shall be disposed of in accordance with North Carolina

application for payment.
b. The owner's Environment Health and Safety Center, and other Owner representatives, may
periodically evaluate the project for compliance with these requirements. Noted deficiencies will
be provided to and discussed with the Owner project representative.
5. The Contractor shall insure that streets connecting to the projects are protected from mud, sand,
stone, litter, or debris in any form. All mud collected on vehicle wheels shall be cleaned off before
leaving the construction area. Should any mud or debris from the project collect on the streets, it
shall be removed immediately to prevent any hazards to vehicular or pedestrian traffic, as well as
from entering the storm sewer. The contractor is prohibited from discharging any waste products from
concrete trucks or from concrete coring work, or any other unsuitable construction materials or
products into the storm sewer system. The contractor shall have the cost of the clean up of any
such unauthorized discharge from the project deducted from the contractor's application for payment.
All streets adjacent to the project site shall be cleaned of construction related debris, dust, and mud
daily. The contractors shall consider in the preparation of bids that the Owner will require cleaning of
adjacent streets daily. Should the contractor fail to comply with this requirement, the Owner reserves
the right, with 24 hours prior notice to the contractor, to clean the adjacent streets. In such case
the cost of the street cleaning shall be deducted from the contractor's application for payment.
6. Provide appropriate measures, such as block and gravel filters or silt fences, during construction as
required to protect catch basins, storm drains, and streams from the entry of all silt and construction
debris. Contain the residue from the cleaning of ready -mix trucks, wheelbarrows, concrete buddie's,
etc. and remove from the Owner's Facility with other refuse. No dumping of debris into drains or
catch basin is permitted. Contractor is responsible for cleaning or replacing drain lines if a violation
occurs.

any land disturbing activities and shall be required to hold a pre -construction meeting between
the Project Representatives and a representative from NCDENR and EPA.
2. Install temporary Erosion and Sedimentation Control Measures (silt fencing and inlet protections)
and tree protection fencing. Clear only as required to install these devices.
3. Install construction fences for contractor staging and laydown area and for temporary soil stock
pile area.
4. Call NCDENR for an on-site inspection by an Environmental Engineer to obtain a certification of
compliance, as required by NCDENR.
5. Begin demolition and clearing and grubbing. Maintain devices as needed. Stockpile topsoil and
suitable fill material in established stockpile area. Dispose of waste material off-site (Contractor is
responsible for all erosion and sedimentation control measures and obtaining permits for the
off-site disposal area).
6. Areas to be left dormant for longer than 14 calendar days shall be temporarily stabilized within
seven days.
7. Contractor is to conduct a weekly site inspection and after each rainfall event to determine which
devices need maintenance, repair, etc., and to ensure that the erosion control measures are
performing adequately. Contractor shall determine during weekly inspections which areas can
be permanently and temporarily seeded.
8. Stabilize site as areas are brought to finished grade with vegetation or stone base. All areas
indicated to be graveled shall be stabilized with stone as soon as they are brought to final
grade. All areas indicated to be paved shall be paved accordingly as shown on the plan. Maintain
diversions and inlet protection until site is completely stabilized.
9. Fertilize, seed and mulch all pervious areas according to the seeding schedule. See specifications
for additional information.
10. When construction is complete and all pervious areas are stabilized, call NCDENR for an inspection
by an Environmental Engineer.
11. On approval from the Environmental Engineer, remove any silt fences, diversion berms, and Inlet
protections, and re -grade and seed or stabilize any resulting bare areas.
12. When vegetation has become established, call NCDENR for a final site inspection by an
Environmental Inspector. Obtain a Certification of Completion.
