Enclosure C




A. Aquatic habitats including:


(1) Food chain production




A.1. {Description of Habitat}



Food chain production exists in the area around the structure.


(2) General habitat


a. Nesting e. Migration


b. S
pawning f. Feeding


c. Rearing g. Escape Cover


d. Resting h. Other



A.2. {Description}




Little Conneauttee

Creek and adjacent flood plain areas do provide general



Habitat for terrestrial and aquatic species.


(3) Habitat for threatened and endangered plant and animal species (Discuss



results of Supplement Form #1).



A.3. {Discussion of Habitat}


No threatened or endangered species exist in the project area


(
See PNDI response letters)


(4) Environmental Study Areas

a. Sanctuaries



A.4.a. {Description of Habitat}


This project is not part of a sanctuary.



b. Refuges



A.4.b. {Description of Habitat}


This project is not part of a refuge.




(5) If project proposes a stream relocation, a stream enclosure, or dredging,


provided a description of the instream macroinvertebrate community.



A.5. {Description}


The stream will be diverted thru the center of the span by th
e use of sand


bags and/or concrete barriers to permit placing the substructure footings.

Erosion and Sedimentation controls will be used.



B. Water Quantity and Streamflow


(1) Natural drainage patterns



B.1. {Description}



Natural drainage patterns do exist within
Little Conneauttee

Creek and adjacent



areas.






(2) Flushing characteristics



B.2. {Description}



The vegetation along the stream banks and within the flood plain area of



the stream may provide

some flushing characteristics.


(3) Current patterns



B.3. {Description}


The present current pattern is not causing scour at the existing structure


and only minor bank erosion upstream and downstream.


(4) Groundwater discharge for baseflow



B.
4. {Description}

There are no areas within the project limits which provide ground water

discharge.



(5) Natural recharge area for ground and surface waters



B.5. {Description}

There are no natural recharge areas within the project limits.


(6) Storm a
nd floodwater storage and control



B.6. {Description}

Some of the flood plain areas of
Little Conneauttee

Creek may provide short

term storage areas for excess runoff.



C. Water Quality


(1) Preventing Pollution



C.1. {Description}

The vegetated fl
ood plain has the ability to filter some pollutants which

may be in the runoff. Erosion pollution controls will be properly implemented

and closely monitored during construction. These measures will follow the

Department of Environmental Protection Chapter

102 regulations, PA DOT Pub. 408

specifications and RC
-
70M standards for Roadway Construction. The Erosion

Pollution controls will insure that the stream water quality is protected.


(2) Sedimentation control and patterns



C.2. {Descript
ion}

The root masses of the vegetation which lines the streambank help anchor the

soil which reduces the potential for sedimentation caused by erosion of upland

areas.

Sedimentation Controls will be properly implemented and closely monitored

during constru
ction. These measures will follow the Department of Environmental

Protection Chapter 102 regulations, PA DOT Pub. 408 Specifications and RC
-
70M

Standards for Roadway Construction. The Sedimentation Controls will insure that

the stream water quality is prot
ected.


(3) Salinity distribution



C.3. {Description} N/A





(4) Natural water filtration




C.4. {Description}


Little Conneauttee

Creek is not considered a significant source for natural




water filtration.



D. Recreation


(1) Gam
e Species



D.1. {Description}

No game species were identified within the area to be disturbed by

construction.


(2) Non Game Species



D.2. {Description}

No non
-
game species were identified within the area to be disturbed by

construction.


(3) Fishing



D.3. {Description}

Little Conneauttee

Creek is not listed as a stockable trout stream, according

to the Pa. Fish & Boat Commission.


(4) Hiking



D.4. {Description}

The project site has no marked hiking trails.


(5) Observation (plant/wildlife)



D.5.
{Description}

The project area may provide some recreational value for the observation

of plants and wildlife, although there are no designated observation areas.


(6) Other



D.6. {Description} N/A



E. Upstream and Downstream Property



E. {Descri
ption}



The project area is surrounded by fields and light brush with a few



small trees.



F. Other Environmental Factors Determined by Site Investigation



F. {Description}



There are no wetlands in the project area. See attach
ed Wetland Delineation
