Plants With a Purpose 

This section includes lists of plant combinations that can be used to mimic the natural 

communities of plants found in wetlands, meadows, forests, etc. They can be used to create, 

restore or enhance existing habitat for wildlife. Also included are plants that can be used in solving 

problems such as stabilizing soils, or for specific landscaping uses. No matter what the purpose, 

it is imperative that species are chosen to suit planting site conditions and the physiographic 

location of the site. None of these lists are complete – there are additional suitable plants in 

this guide (and even more native species not included in this publication) that would suit these 

purposes. This document is intended to give project planners guidance in choosing appropriate 

plants for various projects, and additional learning is encouraged. For the most ecologically 

“correct” habitat restoration projects, consultation with professionals is recommended, as there 

are other factors to consider that are not addressed here.

Plants for Forest or Woodland Plantings 

Forests contain a diversity of plant types 

arranged in vertical layers, from the tallest 

(canopy or overstory) trees, through the 

understory of shorter trees and shrubs, to the 

forest floor or ground layer of low shrubs and 

herbaceous plants. Forest types are classified 

by the dominant trees present (e.g., oakhickory-pine 

forest). Plant species occurring 

together in these different forest types are a 

function of the climate, altitude, geology and 

physiographic location, soil type, moisture, 

sunlight, and other conditions. So many 

combinations of plants occur in these different 

forests that space limitations prevent listing 

them all. Instead, the following represent 

plants found in a few of the more common 

forest types in the Chesapeake Bay watershed. 

These lists provide the basis for a viable forest 

or woodland project. Common ferns, grasses 

and herbaceous plants for the ground layer are 

listed separately, as they may occur in many 

of the forest types in various combinations. 

Remember to match the plants’ growth 

requirements with the site conditions. 

For new projects at open sites, it may take 

years for young trees to provide adequate 

shade. Consult other restoration resources 

and/or professionals for alternative methods

Vines 

Any of the vines included in this guide may 

be found in woodlands, occupying various 

vegetative layers, from the ground up. 

Slopes of any kind are prone to erosion from rain, runoff; wave action, stream or river currents, and foot or lawnmower traffic. Plants with deep, 

spreading root systems help prevent erosion by holding soil in place. Some plants that are particularly well suited to and recommended for holding or 

stabilizing soils on a dry upland slope or hillsides such as a sloping yard or road embankment are listed below. 

However, any plant suited to the site’s sun, soil, and moisture conditions that could be planted on a flat surface could be planted on a slope, as long 

as the slope is accessible. Plants that naturally occur on slopes or hillsides can be found by searching the “habitat” notes provided with each plant in 

this guide. 

For plants to use on a tidal shoreline, see the list of saltmarsh or freshwater marsh plants. For plants to use on a stream, pond or riverbank, see the 

list of freshwater marsh plants.

A search through this guide will reveal literally hundreds of plants of all types that will flower or fruit 

in spring or fall, providing a wide variety of choices to color a native landscaping project and to 

offer a diversity of food for wildlife. Remember to consider trees, shrubs and vines when choosing 

plants for their flower color; and to include fruit color in the palette. The fall color of many plants, 

particularly grasses, trees, shrubs and vines adds interest to the landscape. A landscape planned 

for seasonal color, throughout all seasons of the year, can also provide year-round food, cover 

and nesting structure for wildlife.

Deer Resistant Plants 

Gardeners challenged by browsing deer often look for a definitive list of plants that deer will leave 

alone. Unfortunately, deer are not quite that predictable. In areas where high populations of deer 

have over-browsed the woodland understory, they are likely to eat any plant they can find to 

survive. Gardeners and habitat restorationists are strongly encouraged to use other appropriate 

barriers to exclude deer, in consultation with a local wildlife agency. Plants marked with an 

asterisk (*) may be browsed occasionally.

Landlord has no responsibility for providing, maintaining or 

improving access to the leased premises. Bills of Sale must 

contain the same statement.

VII. SHORELINE PROTECTION PROGRAM 

A. Application Procedures 

1. The “shoreline” is considered to be the existing shoreline at mean 

high water. 

2. Prior to the construction or repair of a pier, dock, boathouse, boat 

ramp, marine railway, bulkhead, retaining wall, or sea wall 

(“Shoreline Improvements”) or the installation of any erosion 

control measures or excavation in any areas that may affect the 

shoreline, Tenant, must submit a Construction Application to 

Landlord in accordance with Section II (B) of these Rules and 

Regulations. Landlord will make an on-site inspection of the area 

to determine if what the applicant has proposed should be allowed 

or if another type of measure may be more appropriate. No 

construction may begin until the Tenant has received Landlord’s 

written Approval and obtained all required local, state and federal 

permits and authorizations, including but not limited to all permits 

required by the Maryland Department of the Environment, and the 

U.S. Army Corps of Engineers. 

B. Specifications and Procedures 

In addition to the applicable local, state and federal laws, and all 

requirements set forth by the applicable permitting authorities, the 

following specifications shall apply. Should any specification herein 

conflict with any applicable local, state, or federal law or regulation, the 

most restrictive requirement shall apply. 

1. Piers or Docks 

a. Piers may be permanent, floating, or a combination of both 

and may not exceed a total length of fifty (50) feet (or extend 

more than fifty (50) feet from the shoreline). If the pier is 

located in a cove or in a stream, the length may not exceed 

Page 9 of 24

25% (1/4) of the width of the cove or stream where the pier 

is located. 

b. All permanent piers (or permanent sections of piers) must be 

built above the mean high water line. 

c. Piers must be constructed of preservative treated lumber 

and pilings. Concrete, masonry, and metal construction is 

not permitted. Hand railings and covers on piers are 

permitted provided that the sides are open so as not to 

obscure cross vision. Covers are permitted only over the 

pier itself and may not extend out over the water. 

d. Flotation devices for floating piers must be constructed of 

environmentally sound material as approved by Landlord 

and permitting authorities. Styrofoam, barrels or similar 

flotation devices are not permitted. 

e. Piers may not interfere with navigation, present a safety 

hazard, or block ingress or egress to adjoining areas. 

f. If an existing pier must be replaced or repaired (other than 

minor repairs), it must conform to current standards. 

g. Piers may not be anchored or tied to trees at any time. 

2. Boat Ramps and Marine Railways 

a. Ramps must be constructed of poured concrete pads or 

precast concrete panels properly anchored and fastened 

together. Asphalt or other petroleum-based products are 

prohibited. 

b. Ramps may not exceed fifteen (15) feet in width and thirty 

(30) feet in length. The length should not exceed that 

necessary to be functional. 

c. Marine railways may use either treated wood or concrete 

ties. 

d. Marine railways may not exceed fifteen (15) feet in width and 

should be no longer than necessary to be functional. 

Landlord may, however, restrict the length because of site 

conditions. 

3. Erosion Control Measures (Bulkheads, Retaining Walls, Sea Walls, 

Rip Rap, etc.) 

Page 10 of 24

a. No erosion control measure shall significantly alter the 

existing shoreline. 

b. The planting of vegetative cover and/or rip-rapping shall be 

used if adequate to control the problem. 

c. Bulkheads and retaining walls must be constructed of 

preservative treated wood, concrete, or masonry. 

d. The structure shall not significantly detract from the scenic 

value of the area. 

C. Landlord assumes no liability for injury or damage in the construction, use 

or removal of any Shoreline Improvement made by the current or any 

former Tenant. 

VIII. COMPLIANCE; AMENDMENTS 

In the event of Tenant’s failure to comply with these Rules and Regulations, 

Landlord may impose a fee on Tenant of up to $250 per day until such failure is cured, 

which fees shall be due and payable within ten (10) days after Tenant receives a bill for 

the same and/or terminate Tenant’s lease in accordance with its terms. Landlord shall 

have the right to amend these Rules and Regulations at any time as Landlord deems 

reasonably necessary. 

IX. CULTURAL RESOURCE PROTECTION GUIDELINES 

Landlord has developed, in cooperation with the Pennsylvania Bureau of Historic 

Preservation and the Maryland Geological Survey, Division of Archeology, the 

following rules and regulations. The specific intent of these guidelines is to 

provide for the protection of cultural resources, and to avoid any disturbance of 

historic and prehistoric sites except when justified for scientific purposes and/or 

when performed in accordance with such State and Federal regulations and 

guidelines as may apply. 

A. No one shall mar, deface, remove, destroy or in any other way damage, 

any standing structure, ruins, foundation or other man-made feature of a 

potentially historic nature on lands of Landlord, without first having 

obtained the written permission of Landlord. 

B. No one shall perform any sub-surface archaeological investigations, or in 

any way disturb the soil for the purpose of searching for and/or obtaining 

historic or prehistoric artifacts on land of Landlord without having first 

obtained the written permission of Landlord, nor shall same be performed 

without the prior knowledge and written sanction of the following: 

In Maryland: The State Historic Preservation Officer and/or the 

Geological Survey, Division of Archeology 

Page 11 of 24

C. Full and complete reports must be prepared. Said reports shall 

incorporate maps, site profiles, descriptions and photographs of artifacts 

and features, soil descriptions, topography, excavation procedures, 

directions and distance to the nearest water and all such other related 

details as may be required. 

D. Landlord shall be supplied with a copy of each report so generated. The 

appropriate State agency shall be supplied with two copies of same, one 

of which shall contain original photographs. 

E. All artifacts and related material recovered in sub-surface investigations 

shall become the property of Landlord, and shall be turned over to the 

respective State agency. Same shall remain available to Landlord and 

other responsible public and private organizations and agencies for the 

purpose of study and/or public display. 

F. All artifacts must be properly labeled with site number and lot and must be 

readily identifiable by pit and level. Site numbers must conform to the 

trinomial numbering system adopted by both Pennsylvania and Maryland. 

G. All burials encountered during the course of such archeological 

investigations shall be treated with the highest respect, and shall be 

handled on a case by case basis under the strict control of the State 

agency having jurisdiction. It is the policy of said agencies and of 

Landlord, to discourage the removal or disturbance of human remains, 

unless there is a significant scientific purpose to be served by same, and 

unless provisions are made, in consultation with, and with the approval of 

living descendants of the interred, for the timely study and the ultimate 

reburial of the remains. 

H. While the collection of artifacts from the surface is widespread, and 

though not strictly prohibited under these regulations, it does have a 

significantly negative effect on archeological sites. The distribution of 

surface artifacts is the only information available for many sites. Those 

finding artifacts are therefore encouraged to report finds to Landlord so 

that same might be photographed and recorded. 

I. Tenant is required to consult with the appropriate State Preservation 

Office prior to any construction work that may affect surface or subsurface 

archaeological sites, and prior to new additions to existing 

structures or the construction of new structures. 

J. On property which is within the boundaries of Federally-regulated projects 

such as the Conowingo Hydro-Electric Project (F.E.R.C. No. 405), 

Tenants' properties require additional precautions regarding cultural 

resources under the provisions of the National Historic Preservation Act of 

Page 12 of 24

1978 (section 106), Executive Order 11593, and the regulations of the 

Advisory Council on Historic Preservation (36 CFR 800). 

X. CONTACT INFORMATION 

DISCLAIMER: The following list is intended as a reference to the 

Tenant for contacting the municipalities or agencies that may require permits or 

approvals for specified construction activities. The list is not intended to be an 

exclusive list and Landlord makes no guarantees or warranties as to the accuracy of 

the information contained herein below. Tenant is responsible for determining which 

federal, state, and/or local laws apply to their proposed construction activities and to 

contact the applicable government or agency as required by said laws.

FORM LEASE 

LEASE 

THIS LEASE AGREEMENT (this “Lease”) is made ____ day of __________________, 2010 (the 

“Effective Date”), by and between Exelon Generation Company, LLC (“Landlord”) and 

__________________________________________(“Tenant”). 

BACKGROUND 

A. Landlord, as successor by merger to PECO Energy Power Company, is the owner of a parcel of 

land located __________________ County, Maryland, identified as Lot No. __________, as outlined in 

red on the plan attached to this Lease as Exhibit A (the “Land”). 

B. Landlord and Tenant desire to enter into a lease of the Land on the following terms and 

conditions. 

1. Term. Unless sooner terminated in accordance with the terms of this Lease, Landlord 

agrees to lease the Land to Tenant for a term beginning on the Effective Date and ending on September 

30 th of the calendar year following the Effective Date (the “Term”). Thereafter, this Lease shall continue 

upon the same terms and conditions, subject to the adjustment of Rent in accordance with Paragraph 2 

hereof, from year to year until terminated by either party by written notice at least thirty (30) days prior to 

the expiration of the then current term. 

2. Payment of Rent. Tenant agrees to pay to Landlord annual rent in the amount of 

$_______ (“Rent”) on the first day of September, except, however, that payments of Rent may be prorated 

on a monthly basis for partial years. Tenant will send or deliver the Rent to Exelon Generation 

Company, LLC, 2301 Market Street, N3-3, Philadelphia, PA 19103, Attn: Real Estate & Facilities, unless 

Landlord notifies Tenant in writing that the Rent should be sent or delivered to another address. Except 

as otherwise provided herein, Landlord is not required to send Tenant a bill for the Rent, and the lack of a 

bill does not mean that Tenant is not required to pay Rent on or before the date set forth above. The Rent 

shall increase annually by the amount of three percent (3%). Tenant shall pay to Landlord the adjusted 

Rent within five (5) days after receipt of a bill from Landlord for the adjusted Rent amount. Landlord 

reserves the right to charge Tenant as additional rent Landlord’s costs arising out of this Lease, including 

without limitation the cost of enforcing the provisions of this Lease. 

3. Late Charge. Tenant must pay the Rent by the first day of each September. If the Rent is 

not received by Landlord within ten (10) days after the Rent is due, Tenant must pay an additional charge 

equal to five percent (5%) of the overdue Rent. 

4. Condition of Land. Tenant has inspected the Land before signing this Lease. Tenant

representations to Tenant concerning the condition of the Land. 

5. Maintenance and Repair; Ownership of Buildings and Structures. Tenant owns and is 

solely responsible for all buildings and other structures on the Land. Tenant agrees to maintain in good 

condition all buildings and structures on the Land, including without limitation all sheds, outhouses, decks,

expiration or earlier termination of this Lease, Tenant will leave the Land in at least as good condition as 

when this Lease began, except for normal wear and tear. 

6. Non-Interference. Landlord may use the Land to operate Landlord’s facilities, including 

without limitation Conowingo Hydro-Electric Station, Muddy Run Pumped Storage Facility and Peach 

Bottom Generating Station (the “Project”). Tenant understands that efficient and economical operation of 

1


the Project is the main purpose of Landlord’s use of its property including the Land. Tenant understands 

that the Landlord’s operation of the Project may limit Tenant’s use of the Land from time to time. 

Regardless of what else this Lease says, Tenant will not interfere with Landlord’s use of the Land or the 

use of the Land by Landlord or its affiliates for the Project. Tenant waives or gives up any rights to file a 

lawsuit against Landlord or its affiliates for anything relating to the maintenance, operation or new 

construction of the Project or the use of the Land for Landlord’s corporate purposes. 

7. Landlord Reservations. Landlord may grant easements (the right to use parts of the 

Land) over any part of the Land to others for any purpose, such as (a) roads and/or highways; (b) utility 

lines, either underground or overhead. All standing timber on the Land shall remain the property of 

Landlord. Tenant may not cut, remove or destroy any timber nor remove any rock, stone, gravel, soil or 

other material from the Land. 

8. Rules and Regulations. Tenant’s use of the Land is subject to Landlord’s rules and 

regulations, a copy of which is attached hereto as Exhibit B as they may be amended from time to time 

(the “Rules and Regulations”). Landlord shall provide Tenant with copies of all changes in the Rules and 

Regulations as they occur. FAILURE TO COMPLY WITH ANY OF THE RULES AND REGULATIONS 

WILL BE CONSIDERED A VIOLATION OF THE TERMS AND CONDITIONS OF THIS LEASE 

AGREEMENT AND MAY RESULT IN A FEE OF UP TO $250.00 PER DAY IMPOSED AGAINST 

TENANT BY LANDLORD AND/OR TERMINATION OF THE LEASE. In addition to Landlord’s right and 

option to assess fees against Tenant and to terminate the Lease, Landlord has the right but not the duty to 

enter the Land and cure any violation of the Rules and Regulations or other terms and conditions of this 

Lease, and to assess all costs incurred by Landlord as a result of curing any such violation(s) against 

Tenant. 

9. Use of Land. Tenant shall use the Land only for a vacation retreat and recreational 

activities. Tenant shall not: 

(a) USE OR OCCUPY THE LAND AS A PRIMARY PERMANENT RESIDENCE.

Landlord has no responsibility for providing, maintaining or improving access. 

12. Inspection of Premises. Landlord, its employees and representatives may inspect the

Landlord will send Tenant a bill for the real estate taxes and Tenant will reimburse Landlord for the real 

estate taxes as additional rent within thirty (30) days after the date of the bill. 

14. No Waiver. Landlord is not required to enforce this Lease. If Landlord does not enforce a 

part of this Lease, this does not mean Landlord cannot enforce the same part, or a different part, later. 

The payment of Rent by Tenant after Tenant violates this Lease does not mean that the violation of this 

Lease is forgiven. 

15. Compliance with Laws. Tenant agrees to comply at its expense with all Federal, state 

and local laws that apply to Tenant’s Improvements or Tenant’s use of the Land. It is Tenant’s 

responsibility to be aware of all laws that apply to the Land.

contractors, representatives or guests on or near the Land. If a claim is made against Landlord because 

of something that Tenant, its contractors, representatives or guests do on the Land, Tenant shall pay all of

Landlord pays any money in order to settle or defend the claim, Tenant shall pay Landlord the amount that 

Landlord paid. 

17. Insurance. (a) Tenant will be solely responsible for purchasing insurance to cover 

damage or theft of the Tenant’s Improvements and personal property located on the Land. Tenant

company or companies acceptable to Landlord. Tenant shall furnish Landlord with evidence of such 

insurance in the form of a certificate of insurance. The certificate shall name Landlord as an additional 

insured, and provide for a waiver of all rights of subrogation which Tenant’s insurance carrier may have 

against Landlord. 

18. Waiver of All Claims. Tenant understands and recognizes that, by signing this Lease, 

Tenant waives any and all claims against Landlord relating to the Land, Tenant’s Improvements or 

personal property thereon or any previous leases of the Land. This includes, but is not limited to, claims 

for lost value of Tenant’s property; lost use of the Land; or, loss, removal or destruction of Tenant’s 

Improvements or personal property. Tenant further waives any claims for damages grounded upon an 

expectation of future gain, restitution or unjust enrichment.

violates this Lease, Landlord can terminate the Lease at a later date. 

20. Removal of the Tenant’s Property. Prior to the expiration of this Lease or within ninety 

(90) days after the earlier termination of this Lease due to an Event of Default or otherwise, Tenant shall 

remove all of Tenant’s Improvements and personal property, including trailers, mobile homes and 

personal belongings, owned by Tenant and restore the Land to a condition satisfactory to Landlord, unless 

Landlord has previously approved the sale of the Tenant’s Improvements in accordance with the Rules 

and Regulations and has issued a new lease to the purchaser of the Tenant’s Improvements. In the event 

Tenant fails to remove the Tenant’s Improvements and personal property prior to the expiration of this 

Lease or within ninety (90) days after the earlier termination of this Lease, then the Tenant’s 

Improvements and personal shall become the property of Landlord without any further act or notice by 

Landlord to Tenant. Landlord may thereafter occupy, sell, lease, repair or remove Tenant’s Improvements 

and personal property. However, in the event Landlord elects to remove Tenant’s Improvements and 

personal property, Tenant agrees to pay Landlord the cost incurred by Landlord for such removal within 

thirty (30) days of receipt of a bill from Landlord.

or (iii) by recognized overnight carrier, to the other party at its address as follows:

If to Tenant: 

If a notice sent to Tenant by certified mail is not accepted by Tenant, Landlord may post the notice at the 

Land. 

22. Brokerage Commissions. There are no commissions or fees to be paid to any real estate 

broker or salesperson for this Lease. If Tenant has agreed to pay any commission or fee to a real estate 

broker, Tenant will pay that commission or fee. If Landlord has agreed to pay any commission or fee to a 

real estate broker, the Landlord will pay that commission or fee. 

23. Federal Energy Regulatory Commission (“FERC”). The Land is part of a project licensed 

by the Federal Energy Regulatory Commission (FERC). Because of the FERC License the following 

requirements apply: 

(a) Tenant’s use of the Land will not endanger health, create a nuisance or otherwise 

be incompatible with the recreational use on any part of Landlord’s land. Tenant will take all reasonable 

4


precautions to ensure that the use and maintenance of the Land will protect the scenic, cultural, 

recreational and environmental value of the Land.

of its costs and expenses, including without limitation attorneys’ fees, incurred by Landlord in enforcing 

Tenant’s obligations under this Lease whether or not Landlord files a lawsuit against Tenant. 

28. No Assignment. Tenant shall not assign, sublease or otherwise transfer or encumber this 

Lease without the prior written consent of Landlord. Tenant shall make all requests for Landlord’s consent 

to assignment in accordance with the Rules and Regulations. Any assignment without the prior written 

request of Landlord shall be null and void. 

29. Entire Agreement. This Lease replaces and cancels all other leases between Landlord 

and Tenant for the Land. Tenant understands the promises in this Lease shall be binding upon Tenant. 

This Lease contains the full and complete agreement between Tenant and Landlord. Any change, 

modification or waiver of the promises in this Lease may only be made by a written agreement signed by 

Landlord and Tenant. No promises were made by Landlord to Tenant other than those promises

Re: Conowingo Hydroelectric Project, FERC Project No. 405

Filing of the Initial Study Report Meeting Notes Summary 

Dear Secretary Bose: 

In accordance with Title 18 Code of Federal Regulations (18 C.F.R.), Section 5.15 (c)(3) of the 

regulations of the Federal Energy Regulatory Commission (Commission or FERC), Exelon 

Corporation, on behalf of its wholly-owned subsidiary, Exelon Generation Company, LLC 

(Exelon), encloses for filing the Initial Study Report Meeting Notes Summary for the relicensing 

of the Conowingo Hydroelectric Project (Conowingo Project), FERC Project No. 405, and the 

Muddy Run Pumped Storage Project, FERC Project No. 2355. 

Exelon is filing this document with the Commission electronically. To access the document on 

the Commission's website (http://www.ferc.gov ), go to the “eLibrary” link, and enter the docket 

number, P-405 or P-2355. Exelon is also making the document available for download at its

Initial Study Report Meeting 

Meeting Notes Summary 

March 9-11, 2011 

Darlington Volunteer Fire Department 

2600 Castleton Road, Darlington, MD 

List of Attendees: See Attachment A 

Introductions, Meeting Purpose, and Process Timeline 

Colleen Hicks (Exelon) opened the meeting and welcomed everyone. Parties introduced 

themselves and gave their affiliation. Tom Sullivan (Gomez and Sullivan) described the meeting 

structure and reviewed the meeting agenda. Each study was scheduled to have approximately 20 

minutes for presentation followed by questions and discussion. Tom Sullivan also provided an 

overview of the next steps in the ILP process (See Attachment B-Meeting Presentation). 

Larry Miller (USFWS) raised concern that the stakeholders have incomplete studies with which 

to make judgments regarding requests for the Year Two study season. Shawn Seaman (MDNR), 

Mike Hendricks (PFBC) and Andy Shiels (PFBC) stated that there is not enough time from a 

process perspective to properly design the Year Two spring studies. The stakeholders felt that 

they will not have enough time to file comments, discuss results, and participate in designing 

Year Two studies. Mike Helfrich (Riverkeeper) stated that the delay with some study reports 

places the stakeholders at a disadvantage by holding up the entire process. In light of these 

concerns there was a specific request made to push the license application filing date to a point 

farther out in time. Tom Sullivan indicated that the Federal Power Act precludes pushing back 

the license application filing date. Tom Sullivan also indicated that Exelon is prepared to 

perform necessary Year Two studies and that Exelon has met all required regulatory obligations 

by filing complete reports where they are available and report summaries in lieu of complete 

reports where necessary. Emily Carter (FERC) also commented that the stakeholders will have 

the ability to comment throughout the licensing process, and if FERC determines that the 

stakeholders have legitimate concerns about the conducted studies that are not addressed, Exelon 

could be required to complete additional studies in 2012 or later to fill-in information gaps. 

Tom Sullivan (Gomez and Sullivan) went over criteria for proposing a new study, including the 

7 criteria for new studies. Andy Shiels (PFBC) asked if there was a study report matrix outlining 

the studies with expected and actual completion dates, and indicated it would be helpful for 

Exelon/FERC to provide this information and maintain it as “living document” (See Attachment 

C-Study Report Schedule).

schedule for this study. Andy Shiels asked that a comparison (physical conditions, attraction 

flow etc.) be made of Conowingo East Fish Lift with other facilities that successfully pass 

sturgeon species, specifically those facilities at Holyoke Dam. Andy noted that Holyoke has 

passed some sturgeon (> 100 fish over 30 years) while Conowingo has not. Steve Leach 

described the mechanical differences at the fish lift facilities and the differences in the river 

characteristics (i.e., river width). Steve mentioned that attraction flows are different at the lifts. 

Availability of sturgeon in the river was also mentioned as the reason for the Conowingo East 

Fish Lift not passing sturgeon. Andy Shiels asked if the East Fish Lift at Conowingo is sufficient 

to pass sturgeon should they become available in the Susquehanna River. Don Pugh (American 

Rivers) indicated that the East Fish Lift is a surface entrance and that is a major difference 

compared to the spillway lift at Holyoke Dam, which is several feet deep. However, the East 

Fish Lift may be comparable with the tailrace lift at Holyoke Dam. It was decided that Exelon 

would provide a conclusion on whether the East Fish Lift is capable of passing sturgeon species- 

Action Item. 

Mike Helfrich suggested that an effort be made to ask river guides, anglers, bait shop owners, 

etc. to see if they had any information about sturgeon presence. He indicated that may be a 

useful method of gathering data on presence/absence of sturgeon in the river. 

Conowingo 3.16 – Instream Flow Habitat Assessment below Conowingo Dam (Kirk Smith) 

Kirk Smith (Gomez and Sullivan) presented the study objectives, work completed, findings, and 

schedule for this study. Geoff Smith asked what the source of the macroinvertebrate data was to 

develop the EPT curves, and why they were included in the assessment. Tom Sullivan indicated 

that the curves were developed in consultation with the resource agencies, and that these species 

were being assessed, at the resource agencies request, because of a relative lack of abundance in 

the study reach. Bill Richkus (Versar) suggested combining study summary tables 3 and 4 in the 

study report. 

Conowingo 3.19 – Freshwater Mussel Characterization Study (Bill Ettinger) 

Bill Ettinger (Normandeau) presented the study objectives, work completed, findings, and 

schedule for this study. Matt Ashton (MDNR) indicated that he had major disagreements on the 

conclusions drawn from the study results, and how flow peaking may be impacting mussel 

4

diversity. Matt also had concerns about how the sampling methodology was established, and 

thought the sampling areas were not representative of the entire river. Matt stated that many 

areas were not sampled, especially on the west side of the river. There was a concern from some 

stakeholders that a few large mussels found in the study are the ones that have found refuge in 

areas more protected from peaking operations, and that they do not indicate a healthy population. 

Don Pugh also expressed disagreement with the study conclusion that Conowingo operations 

have no impact on mussel abundance and composition. He noted that the Catch Per Unit Effort 

(CPUE) increased in the lower portions of the study reach, away from the influence of the 

Conowingo Project. 

Don Pugh requested that the report tables and appendices be made available in electronic form. 

Bill agreed to make the data available to all interested parties on March 14, 2011-Action Item. 

Andy Shiels asked why eastern elliptio is rare above Conowingo Dam but dominant below the 

dam. Bill said others have hypothesized that this difference may be due to the presence of 

American eel, while Matt Ashton suggested that there may be water quality influences as well. 

It was agreed that a conference call would be scheduled to discuss MDNR comments on the 

study methodology and results. The call was scheduled for Friday, March 25, 2011 from 9 am- 

Noon-Action Item. Interested stakeholder participants were Matt Ashton, Don Pugh, Geoff 

Smith, Shawn Seaman, Mike Helfrich, Steve Minkkinen, and Andy Bernick. 

Session 2: Fish Passage 

Conowingo 3.2 – Downstream Fish Passage Effectiveness Study (Jennifer Griffin – Phone) 

Jennifer Griffin (Normandeau) presented the study objectives, work completed, findings, and 

schedule for this study. Don Pugh asked if the proposed blade strike model would consider if the 

turbine blade was blunt or sharp, and what was the turbine configuration at Conowingo. Jennifer 

stated that she would research the turbine design at Conowingo and address this issue in the 

report-Action Item. Bill Richkus ask whether the entrainment analysis would consider the 

impact of turbine aeration. Jennifer responded that the literature database to be used in the 

entrainment analysis did not indicate whether turbines were aerated or not, but that she would 

investigate the issue further and address it within the study report to the extent possible-Action 

Item. Don Pugh asked whether the turbine/runner configuration (i.e., wicket gates, guide vanes) 

would be factored into the entrainment analysis. Jennifer said that this will be addressed in the 

study report. Andy Shiels asked which projects would be used as a comparison to Conowingo. 

Jen Griffin responded that she has not narrowed the list at this time, but this component will be 

described in the study report. 

Conowingo 3.5 – Upstream Fish Passage Effectiveness Study (Eric White) 

Eric White (Normandeau) presented the study objectives, work completed, findings, and 

schedule for this study. Shawn Seaman contended that there was a deviation from the study plan 

in that the tailrace area was to be defined as the area from the powerhouse to the downstream end 

5

of Rowland Island. Eric stated that extending the definition to the downstream end of Rowland 

Island would add one fish to “the number of fish available” in the tailrace in the report. 

Mike Hendricks stated that the composite telemetry animation showing all of the tagged fish 

ends on April 29, and that a composite animation of all fish through the end of the study period 

would be helpful. Doug Royer (Normandeau) mentioned that the file sizes were very large, and 

to alleviate this problem, he would create 10-day animations over the study period and provide 

this information to stakeholders-Action Item. 

Larry Miller indicated that he would like to know more about what happened to the fish that 

dropped downstream from the study tailrace after tagging and release. Eric indicated that only 

mobile tracking was available for the area downstream of Spencer Island. 

John Mudre (FERC) asked how fish that passed back downstream after being lifted were 

counted. Eric White responded they were only counted once for the study purposes. 

Don Pugh indicated that it would be helpful to have the electronic data of all tagged fish, 

including detection times at each station. Eric indicated that this would be provided-Action 

Item. 

Shawn Seaman noted that most fish appear to be favoring the west side of the river near 

Rowland Island, and appeared to be attracted to the small turbine units (Francis). He also 

indicated the results seemed to show that when flows ramped up to generation the fish left the 

area immediately downstream of the turbines. Bob Sadzinski (MDNR) also noted that only one 

tagged fish was captured in the West Fish Lift, even though several tagged fish were in that area. 

Mike Hendricks recommended investigating the crowder gate operations, and stated that perhaps 

lifts should also be increased in frequency to as often as every 15 minutes, as part of the Year 

Two shad telemetry study design. Ray Bleistine (Normandeau) stated that it is only possible to 

lift every 20-30 minutes; and that the current protocol is to lift a minimum of every hour. In 

terms of Year Two study design, Don Pugh suggested adding to the radio telemetry monitoring 

array, rather than re-positioning, and several stakeholders suggested discontinuing the transport 

of tagged fish from the tailrace down to the Lapidum boat launch for release. 

It was noted that the last fixed telemetry monitoring station was in the trough of the East Fish 

Lift, and there was some manual tracking in Conowingo Pond up to the Norman Wood Bridge. 

A clarification was also made with regard to the fate of tagged fish that passed into Conowingo 

Pond. Six of these radio tagged fish passed Safe Harbor Dam and 2 fish passed York Haven 

Dam. Larry Miller also deployed additional fixed telemetry monitoring stations in the upper 

portions of the river. He agreed to make this data available the group-Action Item. 

Tom Sullivan indicated that a work plan for the Year Two shad telemetry study would be 

circulated to stakeholders by Friday, March 18, 2011-Action Item. He indicated that Exelon 

would like to work with the agencies to refine this study at a meeting on April 7, 2011 if they 

would be willing to participate.

Conowingo 3.6 – Conowingo East Fish Lift Attraction Flows (Ray Bleistine) 

Ray Bleistine (Normandeau) presented the study objectives, work completed, findings, and 

schedule for this study. Andy Shiels asked if there was a correlation between overall river flow 

and fish passage efficiency at the East Fish Lift. Ray indicated that lower flows generally had 

better fish passage, possibly due to a larger percentage of fish finding the fish lift entrance. 

Mike Hendricks asked how passage efficiency was affected by operations, specifically lift 

frequency. Mike suggested that a lift be done every time a project operations change is made. 

Ray Bleistine indicated that this is already done. 

Bill Richkus stated that the statistical analysis of turbine operation and fish catch data were not 

analyzed the way the study plan stated, as the study plan called for correlated matrices. Ray 

responded that the t-test and Pearson correlation did not show any multi-variable correlations. 

Larry Miller and Don Pugh suggested that there were better statistical methodologies available, 

and Larry Miller indicated he would get back to Ray with statistical analysis recommendations, 

after he consulted with the USFWS statistician-Action Item. Larry specifically mentioned 

looking at percentage of shad passed during each specific day, to give a better normalization on 

the day-to-day passage number variability. 

Bill Richkus requested that Table 4.2-2 from the report present data for the 2001-2009 period as 

well-Action Item. Don Pugh asked where the attraction flow velocity probe was positioned. 

Ray stated that the probe was put in the middle of the gate, approximately 15 inches below the 

surface, and that the gate opening was variable. 

Don Pugh and Shawn Seaman stated that the telemetry animations do not support the conclusion 

that operations do not have an effect on fish passage efficiency, since the animations show 

indirect routes taken to get to the East Fish Lift. Ray stated that his statistical analysis does not 

attribute a specific turbine operation to good or bad passage. 

Don Pugh noted that 43% of fish were making forays to tailrace area during the night, when the 

East Fish Lift was not operating. Mike Hendricks mentioned that in the Year Two shad 

telemetry study design, Exelon should examine the effects of running the attraction flow starting 

at dawn. Ray Bleistine explained that starting the attraction flow early could cause gizzard shad 

to congregate and clog the lift entrance. 

Conowingo 3.7 – Fish Passage Impediments Study (Brian Hanson – Phone) 

Brian Hanson (Normandeau) presented the study objectives, work completed, findings, and 

schedule for this study. Don Pugh asked why there are many fish that appear to be traveling 

upriver, only to fall back right before they reach the tailrace. Don said this holds true even for 

fish that do eventually enter the tailrace and pass Conowingo Dam. Brian stated that while there 

are some high velocity areas at the full generation flow, the high velocity area is relatively small, 

and fish can maneuver around those areas. Brian postulated that the multiple forays made by 

some fish were simply a result of individual fish behavior. 

7

Mike Hendricks suggested looking at the tailrace shad telemetry study (Conowingo 3.5) to see if 

velocity is an issue, particularly plots of telemetry spot readings in the tailrace versus generation 

to get an idea of any relationship between generation and fallback-Action Item. 

Conowingo 3.9 – Biological and Engineering Studies of the East and West Fish Lifts (Tom 

Hoffman) 

Tom Hoffman (Gomez and Sullivan) presented the study objectives, work completed, findings, 

and schedule for this study. Larry Miller wanted to ensure that the study report would explain 

the rationale behind the conclusion that providing volitional passage at the West Fish Lift was 

not feasible. Tom Hoffman stated that the report would do so. Don Pugh asked if an increase in 

bucket size and/or attraction flow would be investigated as methods to improve hopper entry. 

Tom indicated these would be explored in the study report. 

Conowingo 3.3 – Biological and Engineering Studies of American Eel (Terry Euston) 

Terry Euston (Normandeau) presented the study objectives, work completed, findings, and 

schedule for this study. Terry Euston mentioned that the sampling dates from the Year One study 

season began 17 days late, and that the goal is to begin sampling around Mid-May as part of the 

Year Two study. 

Don Pugh stated that a wider range of eels may be caught by increasing attraction flows through 

the ramp, or possibly setting up two ramps with differing substrates. Terry stated that it is 

possible that attraction flow issues could be worked out for the 2011 study season. Larry Miller 

noted that nighttime spotlighting has been effective. Larry Miller also mentioned that the 

USFWS sampling on the west side of the river was much more effective, and was wondering 

why there may be such a discrepancy. Terry mentioned flow attraction differences, substrate 

differences, and the late start to the study sampling relative to the USFWS sampling may be 

possible explanations. 

Tom Sullivan indicated that a work plan for the Year Two elver sampling study would be 

circulated to stakeholders by Friday, March 18, 2011-Action Item. 

Muddy Run 3.3 – Entrainment and Impingement Study (Jen Griffin – Phone) 

Jennifer Griffin (Normandeau) presented the study objectives, work completed, findings, and 

schedule for this study. Andy Shiels asked why expected survival at Muddy Run is higher than 

similar projects. Jen Griffin responded that the runner speed and trash rack spacing is different 

than other projects and are better suited for fish survival. Jen Griffin also stated that habitat is 

generally not good near the intakes as well. Sheila Eyler (USFWS) asked if migratory fish 

entrained are counted twice as they would have to pass the turbines twice to go back and forth to 

Muddy Run and back down to Conowingo Pond. Tom Sullivan stated that for some of the fish 

the survival probability should be calculated twice (American eel, but not American shad) as 

they are not necessarily taken out of the population. Don Pugh stated that any entrained 

migratory fish should be considered extirpated from the system. 

8

Larry Miller suggested that the pressure differential experienced by fish moving through the 

water conveyance system at Muddy Run may be problematic for fish survival, and this warranted 

further investigation by Exelon-Action Item. Don Pugh asked for a description of any structures 

(i.e., gates, valves) in the water conveyance system at Muddy Run-Action Item. 

Andy Shiels suggested that the generation/pumping diurnal schedule may have an impact on 

some species more than others, and suggested investigating this relationship further-Action 

Item. 

Don Pugh indicated that egg and larvae entrainment had historically been reported as high, but 

the current report suggests entrainment is more modest. Don asked that the report explain the 

reasons for these differences. 

Muddy Run 3.3 –Adult American Eel Telemetry Study (Terry Euston) 


schedule for this study. Larry Miller asked if Exelon could confirm that the acoustic frequencies 

from the Year One study were input to the ACT (Atlantic Coastal Tag) database, and whether 

Exelon requested to be notified of any detections-Action Item. 

Mike Hendricks asked that appropriate steps be taken to make sure the acoustic receivers for the 

Year Two study can be operated without any interference related to Project noise. Steve Leach 

stated that noise is high near the Project draft tubes, but this should not interfere with the study. 

Don Pugh mentioned that he would like to see the receivers in the canal as close to the Muddy 

Run intake towers as possible, and that they should be tested prior to the study to ensure that 

project noise does not interfere with them. 

Bob Sadzinski asked how often and how many total nights were sampled in Deer and Octoraro 

Creeks, and mentioned MDNR typically nets for 8 or 9 consecutive weeks. Bob mentioned that 

the number of eels that did not migrate may be due to a maturity difference between the in-basin 

and out of basin eels. Terry said that a maturity difference is possible, but that all of the 

indicators (coloring, eyes) suggested that the in-basin eels were silver, just like the out-of-basin 

eels. Terry stated that Exelon’s expectation is to use out-of-basin eels for the Year Two study. 

Muddy Run 3.5 – Nearfield Effects of the Muddy Run Project on Migratory Fishes (Doug 

Royer) 

Eric White (Normandeau) presented the study objectives, work completed, findings, and 

schedule for this study. Sheila Eyler (USFWS) asked why the pit tag reader is impractical at 

Muddy Run. Steve Leach indicated because the antenna read range is small; an array of nearly 

100 antennas would be needed to provide full coverage around the intake/tailrace areas. 

Andy Shiels asked how the cruise speeds were estimated for historic telemetry studies and the 

2010 telemetry study. It was agreed that this item will be addressed in the study report to the 

extent possible-Action Item. For entrainment percentages discussed in the study report, Andy 

Shiels requested that the numerator and denominator be given. Andy also asked what the 

9

velocities were at certain locations in the water column; since the depth-averaged velocity may 

not be the best metric to show when there are potentially complex velocity eddies around the 

Muddy Run tailrace. Terry Euston indicated that the raw data would be reviewed to determine if 

velocities over the vertical water column could be included in the study report, rather than a 

depth averaged velocity-Action Item. 

Thursday March 10, 2011 

Conowingo 3.13 – Study to Assess Tributary Access in Conowingo Pond (Enn Kotkas) 

Enn Kotkas (Normandeau) presented the study objectives, work completed, findings, and 

schedule for this study. Bob Sadzinski asked for clarification of the extra survey and Enn stated 

that it was because of the low pond level due to a LIDAR survey that occurred in mid- 

September. Bob Sadzinski also asked if boat size was taken into account when assessing 

tributary access. Bob Sadzinski indicated that the launches with obstructions (bridges) should 

have signs indicating low overhangs. Andy Shiels requested frequency tables of Conowingo 

Pond waters levels in lieu of the frequency graphs currently included in the study report-Action 

Item. 

Conowingo 3.8 – Downstream Flow Ramping and Fish Stranding Study (Terry Euston) 


schedule for this study. Mike Hendricks requested that arrows showing when the stranding 

surveys occurred be added to the water level figures within the study report-Action Item. 

Don Pugh asked if the individual stranding data could be extrapolated over a season, and if one 

minimum flow yielded less bird predation than another. Tom Sullivan indicated that the study 

was meant to characterize individual events, and that the data was not meant to be extrapolated. 

Don Pugh also asked if an estimate of dewatered areas could be provided for different flow pairs. 

Terry stated that there was not existing aerial photography/mapping under the various minimum 

flow conditions to make an accurate assessment of dewatered area. 

Don Pugh also asked if there was any assessment of connectivity between the stranded areas 

completed, and whether any relationships with connectivity and predation or flow could be 

developed. Terry stated that only a qualitative assessment of connectivity could be completed 

based on data collected as part of this study. 

Conowingo 3.18 – Characterization of Downstream Aquatic Communities (John Pierce – 

Phone) 

John Pierce (Normandeau) presented the study objectives, work completed, findings, and 

schedule for this study. Andy Shiels requested a fish length frequency distribution be completed 

for the 2010 West Fish Lift data (i.e., fish length-weight data) to supplement the current study 

report.-Action Item. 

10

Bob Sadzinski and Andy Shiels expressed concern that collecting fish from different times of 

year may throw off the weight vs. length relationship. Terry indicated that this is possible, but 

there is no way to separate the cumulative dataset out by individual season. Bob Sadzinksi 

suggested that the length/weight relationship regression relationships for yellow perch seem to 

have changed from the 1980s to present. 

Conowingo 3.21 – Impact of Plant Operations on Migratory Fish Reproduction (Steve 

Leach, Brian Hanson – Phone) 

Brian Hanson and Steve Leach (Normandeau) presented the study objectives, work completed, 

findings, and schedule for this study. Mike Hendricks asked when the Year Two study plan 

would be ready for the ichthyoplankton sampling. Terry Euston stated that the ichthyoplankton 

study plan would be circulated to stakeholders on March 18, 2011-Action Item. Mike also 

indicated that there was a need for more field observational information on American shad 

spawning locations in the river below Conowingo Dam. Steve Leach indicated that the Year 

Two ichthyoplankton sampling would help address this issue, along with the results of the 

Instream Flow Study (Conowingo 3.16). 

Conowingo 3.24 – Zebra Mussel Monitoring Study (Steve Adams) 

Steve Adams (Normandeau) presented the study objectives, work completed, findings, and 

schedule for this study. It was asked if Exelon is doing any treatment for zebra mussels. Kim 

Long (Exelon) indicated that Exelon is considering treatment, but that there is no current plan in 

place. 

Muddy Run 3.4 –Impacts of Muddy Run Project on Conowingo Pond Fishes (Terry 

Euston) 


schedule for this study. Andy Shiels asked if black crappie was present and if the population was 

healthy. Terry Euston indicated they are present, but have always been lower in abundance than 

white crappie. Andy Shiels asked why relative weight was used in this study report, while 

condition factor was used for fish lift data evaluated as part of Conowingo 3.18. Terry Euston 

indicated that MDNR has used relative weight recently and this study tried to mimic their 

methods for easy comparison. Aaron Henning (SRBC) asked if the data showed any logperch 

within Conowingo Pond. Terry stated that this species had been caught in all gear types. 

Muddy Run 3.6 – Interactions with the PBAPS Thermal Plume (Terry Euston) 


schedule for this study. Larry Miller asked for clarification as to the withdrawal capacity and 

cooling water temperature differential at the Peach Bottom Station. Terry replied that the Peach 

Bottom withdrawal capacity is approximately 3,450 cfs, while the design cooling water 

temperature differential is approximately 22°F. 

11

Session 3: Water Quality 

Conowingo 3.1 – Water Quality in Conowingo Pool and below Dam (Ray Bleistine, Steve 

Adams) 

Steve Adams and Ray Bleistine (Normandeau) presented the study objectives, work completed, 

findings, and schedule for this study. John Mudre (FERC) asked if the boils of the larger units 

had lower DO readings. Ray indicated that some of the boil readings were rather low, but this 

was primarily during low-flow summertime periods, just after turbine start-up. He then 

mentioned that during low-flow periods the larger units are rarely used. Larry Miller followed 

up with a request that the run times of the turbine units in July and August of 2010 be analyzed 

versus previous years to see if the collected data was a representative sample-Action Item. Bob 

Sadzinski suggested that a GIS map be considered for Conowingo Pond DO levels, to show the 

areas of higher and lower DO. 

Muddy Run 3.1 – Water Quality Study (Ray Bleistine, Steve Adams) 

Steve Adams and Ray Bleistine (Normandeau) presented the study objectives, work completed, 

findings, and schedule for this study. Mike Helfrich requested information related to the dead 

storage volume versus the active storage volume for the Muddy Run Power Reservoir-Action 

Item 1 . Tom Sullivan indicated that Exelon anticipated completing a Year Two study related to 

Water Quality at Muddy Run. 

Conowingo 3.14 – Debris Management (Marjie Zeff) 

Marjie Zeff (URS) presented the study objectives, work completed, findings, and schedule for 

this study. Shawn Seaman (MDNR) asked how the estimates of the amount of debris that sank, 

was removed, and passed were derived. Tom Sullivan (Gomez and Sullivan) responded that the 

source of these estimates will be provided-Action Item. Andy Shiels (PFBC) stated that the 

report should depict where debris along Conowingo Dam is collected and removed-Action Item. 

Conowingo 3.15 – Sediment Introduction and Transport (Marjie Zeff) 

Marjie Zeff (URS) presented the study objectives, work completed, findings, and schedule for 

this study. In response to a question from Larry Miller (USFWS), Marjie Zeff (URS) indicated 

that historic maps would be included in the final report. Woohee Choi (FERC) mentioned that 

wind influences can impact sediment movement when water depths are 20 feet or less. Mike 

Helfrich (Riverkeeper) requested that the study report include the peak flows associated with 

Hurricane Hazel (1954) and Tropical Storms Connie and Diane (1955), as well as the storm 

events examined in the HEC-6 modeling analysis-Action Item. Mike also contended that the 

Hazel, Connie, and Diane storms did not cause significant flood events (greater than ~400,000 

cfs) to result in scour within Conowingo Pond. 

1 The water storage between elevations 520 feet and 470 feet is available for generation purposes at the Muddy Run 

Power Reservoir. The volume of water between these elevations constitutes approximately 60% of the total storage 

in the Power Reservoir. 

12

There was a discussion on the objectives and data sources for the USGS HEC-6 model. Mike 

Helfrich expressed concern that the modeling completed does not address any future storms, and 

that the bathymetry used in the model may be outdated. Marjie Zeff responded that the goal of 

the HEC-6 modeling was to take a more detailed look at historic storm events to better 

understand the local movement and distribution of sediment during those events. 

Session 4: Water Use 

Muddy Run 3.2 –Hydrologic Study of Muddy Run Water Withdrawal and Return 

Characteristics (Kirk Smith) 


schedule for this study. Woohee Choi (FERC) asked why the Muddy Run withdrawal and 

discharges were greater during a 30-day low flow period than the 30-day high flow period. Kirk 

Smith responded that the low-flow and high-flow periods were referring to the Susquehanna 

River flow, and that river flow does not necessarily have any correlation with Muddy Run 

operations. Kirk stated that Muddy Run operations are typically driven by power demand, which 

likely explains the difference. 

Larry Miller requested that if more bathymetry and/or velocity data is collected this year that the 

shad staging area near Sicily Island be included in the survey-Action Item. It was suggested that 

a note be included on the bathymetry map indicating normal pool elevation. Drew Dehoff 

(SRBC) requested that an hourly maximum withdrawal and discharge be included for each 

period in the final report for all analyzed periods-Action Item. 

With regard to the bathymetric mapping of the Muddy Run tailrace, Jim Spontak (PFBC) 

requested that the normal water surface elevation be included on the map, and Andy Shiels 

(PFBC) requested that the location of the Muddy Run draft tubes be included on the map-Action 

Item. 

Conowingo 3.11 – Hydrologic Study of the Lower Susquehanna River (Gary Lemay) 

Gary Lemay (Gomez and Sullivan) presented the study objectives, work completed, findings, 

and schedule for this study. Don Pugh (American Rivers) asked when the Conowingo USGS 

gage had most recently been verified. Gary Lemay responded that he believes it was last year, 

but that it was at minimum flow, which does not apply well to flows at 40,000 cfs, where the 

inconsistencies were being noticed 2 . Only four flow verification measurements have taken place 

since 1980, two of which were below 4,000 cfs, and two of which were above 200,000 cfs. 

Conowingo 3.20 – Salinity and Salt Wedge Encroachment (Gary Lemay) 

2 A review of the USGS gage data reveals that the last verification was in the fall of 2009, at 3,910 cfs 

http://waterdata.usgs.gov/nwis/measurements/?site_no=01578310&agency_cd=USGS 

13


and schedule for this study. Don Pugh (American Rivers) asked if salinity tolerances for youngof-year 

had been provided. Gary Lemay indicated that no analysis had examined those 

thresholds. Bob Sadzinski stated that he could provide data comparing yellow perch young-ofyear 

and egg collections to salinity levels. Follow-up conversations with Bob Sadzinski and Paul 

Piavis (MDNR) yielded information relating to eggs, larval, and young-of-year yellow perch. 

Observational data showed that eggs could tolerate salinities up to 8 ppt. Larvae tolerated 

salinities up to 12-13 ppt. Young-of-year have been collected in salinities as high as 13 ppt. 

Paul Piavis also stated that the preferred salinity levels for these life stages would likely be closer 

to 2 ppt. This is well above the maximum salinity level recorded at any of the salinity stations, 

where the maximum salinity recorded was 0.46 ppt at the MDNR station. 

Conowingo 3.29 – Effect of Project Operations on Downstream Flooding (Gary Lemay) 


and schedule for this study. Woohee Choi (FERC) requested that the HEC-RAS model crosssections 

be provided-Action Item. Woohee Choi (FERC) also requested information related to 

Conowingo’s Flood Operations Plan-Action Item. 

Friday, March 11, 2011 

Session 5: Recreation, Shoreline Management, Cultural Resources 

Muddy Run 3.11 – Recreational Inventory and Needs Assessment (Bud Newell) 

Bud Newell (TRC) presented the study objectives, work completed, findings, and schedule for 

this study. Mike Hendricks (PFBC) noted that a few specific recreation areas had parking 

shortages, such as the mouth of Deer Creek during the hickory shad run. Bob Sadzinski and 

Kevin Mendik (National Park Service) asked if Exelon had a web page showing recreation 

facilities, and what methods of outreach were being employed by Exelon. Shawn Seaman 

(MDNR) expressed concern that perhaps the incorrect groups were being targeted in the 

recreation user survey, and that Exelon should reach out to those who may be interested in using 

the facilities but for whatever reason are not. Andy Shiels stated that where the users originate is 

important, and Bob Sadzinski recommended collecting a zip code from those being surveyed to 

get at this answer. Terry Euston mentioned that the zip code of all anglers interviewed as part of 

the creel survey was recorded. Tom Sullivan requested input for the stakeholder list, and some 

local residents provided suggestions. 

Conowingo 3.26 – Recreational Inventory and Needs Assessment (Bud Newell) 


this study. Lee Haille expressed concern with the 400-yard boating access restriction above and 

below Conowingo Dam. Lee stated that a float line will not stop a security threat, and it restricts 

what would otherwise be good fishing areas. Doug Clark also expressed concern with the time 

limits for the Conowingo Fishermans Park, as he and others he knows like to go nighttime float 

fishing, but they cannot access the boat ramp after certain hours. 

14

A discussion was held relative to the closing of the Rock Run boat ramp, and whether it should 

be addressed in the study report since it is outside the project boundary. Bud Newell (TRC) 

stated that boat ramp would be included in the regional discussion of available facilities, but 

would not receive the same level of treatment as facilities within the project boundary. Several 

stakeholders reiterated that parking at Deer Creek is not adequate for certain times of the year. 

Muddy Run 3.12 – Shoreline Management and Conowingo 3.27 – Shoreline Management 

(Bud Newell) 


these studies. In response to a question from Larry Miller (USFWS), Bud confirmed that Year 

One study results (i.e., wetland, significant habitats) would be considered in the shoreline 

management planning process. 

Muddy Run 3.10 – Creel Survey of Muddy Run Recreation Lake (Mike Martinek) 

Mike Martinek (Normandeau) presented the study objectives, work completed, findings, and 

schedule for this study. Mike Hendricks (PFBC) asked if parking availability was investigated at 

all of the creel survey locations. Mike Martinek (Normandeau) indicated that it was not. Andy 

Shiels (PFBC) stated that it would be helpful if the study report could identify pulses of angling 

activity related to PFBC stocking activities-Action Item. 

Conowingo 3.25 – Creel Survey of Conowingo Pond and the Susquehanna River (Mike 

Martinek) 

Mike Martinek (Normandeau) presented the study objectives, work completed, findings, and 

schedule for this study. It was suggested that the final report include seasonal use, as well as a 

weekday/weekend breakdown of results-Action Item. It was also requested that the lengthfrequency 

distribution based on the creel survey results be included in the final report-Action 

Item. Shawn Seaman requested that the aerial photos from the surveys be included in the final 

report-Action Item. Andy Shiels suggested the black bass catch data be partitioned by season 

(i.e., catch and release)-Action Item. Bob Sadzinski (MDNR) asked for the raw data to be 

included with the report, as well as length-frequency distributions. Tom Sullivan indicated that 

this information will be included in the study report-Action Item. Mike Helfrich suggested that 

creel survey data from for the fisherman’s wharf and Conowingo tailrace be partitioned to 

examine the impacts of the catwalk closing. 

Conowingo 3.32 – Re-evaluate the Closing of the Catwalk (Tom Sullivan) 

Tom Sullivan (Gomez and Sullivan) presented the study objectives, work completed, findings, 

and schedule for this study. Shawn Seaman stated that the study summary included no 

comparison of fishing access at other projects (Safe Harbor) relative to Conowingo. Kevin 

Mendik (National Park Service) said that even though a security consultant made a determination 

that there was a threat posed by re-opening the catwalk, Exelon could still choose to do 

otherwise. 

15

Several stakeholders suggested that Exelon did not investigate the feasibility of re-opening the 

catwalk, since no steps were identified showing what would have to be done in order for the 

catwalk to be reopened, such as completing a cost estimate for increased security presence to 

monitor the catwalk. It was also suggested that fisherman safety (i.e., accidents on the catwalk) 

be documented, as well as a risk assessment analysis to anglers on the catwalk. 

Muddy Run 3.14 – Cultural Resource Review and Assessment (Kirk Smith) 


schedule for this study. In response to a question from Emily Carter (FERC), Kirk stated that 

Exelon hopes to file the Historic Properties Management Plans as part of the project license 

applications. 

Conowingo 3.28 – Cultural Resource Review and Assessment (Kirk Smith) 


schedule for this study. There were no questions or comments. 

Muddy Run 3.13 – Visual and Noise Assessment (Kirk Smith) 


schedule for this study. Mike Helfrich requested that the field notes be provided so that specific 

noise sources could be determined at each assessment site-Action Item. 

Session 6: Terrestrial and Wetland Resources 

Muddy Run 3.9 – Bog Turtle and Rough Green Snake Habitat Study (Deb Poppel) 

Deb Poppel (URS) presented the study objectives, work completed, findings, and schedule for 

this study. Andy Shiels (PFBC) asked why no other herptiles were noted on any of the bog turtle 

Phase I surveys. Deb Poppel responded that the time expended to determine whether the wetland 

was potential bog turtle habitat was limited to the amount of time necessary for the habitat 

evaluation, and additional time was not spent searching for herpetofauna. Because the wetland 

areas investigated were very small, the time needed to make an accurate habitat determination 

was not substantial, and therefore it is not unusual that no animals were observed. However, 

Deb will review her field notes to confirm that no herpetofauna were observed during the field 

collection of information for the overall project area landscape habitat descriptions.-Action 

Item. 

Conowingo 3.12 Water Level Management (Mike Rondinelli) 

Mike Rondinelli (URS) presented the study objectives, work completed, findings, and schedule 

for this study. Doug Clark (Coastal Conservation Association) requested that the study include a 

description of critical water levels associated with the management of Conowingo Pond (e.g., the 

minimum pond level that requires a shutdown of the Peach Bottom Atomic Power Station). 

16

Doug also noted recreational boat access issues at several launches can become apparent at low 

Conowingo Pond levels. 

Conowingo 3.17 – Downstream EAV/SAV Study (Mike Rondinelli) 

Mike Rondinelli (URS) presented the study objectives, work completed, findings, and schedule 

for this study. In response to a question from Larry Miller, Bryan Strawn (URS) stated that the 

vegetative communities below Conowingo Dam were generally similar to those seen in other 

reaches of the Susquehanna. In response to a question from Larry Miller, Mike Rondinelli 

indicated that the growth of EAV appears to be limited by the availability of substrate. 

Muddy Run 3.7 – Transmission Line Avian Interaction Study (Deb Poppel) 


this study. No major comments or questions. 

Muddy Run 3.8 and Conowingo 3.23 – Critical Habitat use Areas for Bald Eagle (Deb 

Poppel) 


this study. In response to a question from Doug Clark, Deb stated that assessment of the eagle 

nest in the Holtwood tailrace was not included as part of these studies, as its management is 

PPL’s responsibility. 

Muddy Run 3.15 and Conowingo 3.30 – Osprey Nesting Survey (Deb Poppel) 


this study. It was agreed that the coordinates of the identified osprey nests should be provided to 

the Pennsylvania Game Commission and the MDNR Wildlife and Heritage Service. Deb 

indicated that a work plan for the Year Two Osprey nesting study would be circulated to 

stakeholders by Friday, March 18, 2011-Action Item. 

Conowingo 3.31 – Black-Crowned Night Heron Nesting Survey (Deb Poppel) 


this study. Deb indicated that a work plan for the Year Two black-crowned night heron nesting 

study would be circulated to stakeholders by Friday, March 18, 2011-Action Item. 

Tom Sullivan stated that Exelon would like to convene a conference call on March 28 th , 2011 

from 1:00 pm to 3:00 pm, and a follow-up meeting on April 7 th , 2011 from 11:00 am to 4:00 pm 

at the Conowingo Visitors Center to discuss the following Year Two study plans, which require 

spring field work commencing in April 2011. 

1. Conowingo 3.3-Biological and Engineering Studies of American Eel at the Conowingo 

Project (i.e., American eel sampling below the Conowingo Dam spillway)

2. Conowingo 3.5- Upstream Fish Passage Effectiveness Study (i.e., American shad radio 

telemetry study) 

3. Conowingo 3.21- Impact of Plant Operations on Migratory Fish Reproduction (i.e.,

4. Conowingo 3.30- Osprey Nesting Survey 

5. Conowingo 3.31- Black-crowned Night Heron Nesting Survey 

6. Muddy Run 3.15- Osprey Nesting Survey 

Several resource agencies stated that they would have to give further consideration to Exelon’s 

proposed meeting schedule before making a determination on whether to participate.
