PROJECT DESCRIPTION The following narrative describes an Erosion and Sediment Pollution Control Plan for the construction of roadway improvements for State Route 2007 known as Chapmans Run Bridge Replacement Project. Construction is located approximately 1.5 miles Southeast from the Village of Clearville along SR 2007 (Big Creek Rd.) in Monroe Township, Bedford County and extends approximately 325 ft or 0.061 miles. The project limits are shown below on the Location Map. This roadway improvement project consists of the following:
• From the beginning of the project (Station 784+75.00) to Station 785+75.00 and from Station 786+87.00 to the end of the project (Station 788+00.00) milling and asphalt overlay is proposed.
• From Station 785+75.00 to Station 786+19.00 and Station 786+43.00 to Station 786+87.00 the roadway and shoulders will be reconstructed and a reinforced concrete box culvert will be constructed over Chapman’s run at Station 786+19.00+00 to 786+43.00.
• Construct a temporary roadway and 2 - 42” pipe culverts downstream of the existing structure at Station 786+58.00 LT/RT and a 36”channel diversion pipe at Station 786+76.00.
All earth disturbances will occur within the public right-of-way and temporary construction easement area. Earth disturbance is associated with the construction of a new box culvert, installation of channel diversion pipes, roadway and shoulder re-construction and a temporary roadway as shown on the plans. The total project boundary area is 1.24 acres. Of this area, 0.65 acres will be disturbed. Based on these areas, an NPDES permit is not required. The approximate center of the project can be found on USGS 7.5’ Quad Map, near Clearville, Pa. at the following location: Latitude: 39o 54’ 5.31” North Longitude: 78o 21’ 23.94” West 102.4(b)(3) Experience of Plan PreparerJohn C.

102.4(b)(5)(ii) SOILS INFORMATION
Soils General The project area is located in central Bedford County and lies within the Ridge and Valley Province. Monroe Township is located in the Appalachian Mountain Section and has bedrock of sandstone, siltstone, shale, conglomerate, limestone, and dolomite formations. The geology consists of open and closed plunging folds with narrow hinges and planar limbs formed by fluvial erosion and periglacial mass wasting. The topography of Monroe Township generally consists of long narrow ridges and broad to narrow valleys. The approximate elevation of the project is 1,295 feet above mean sea level. The project area is surrounded by sparse residential homes and agricultural fields. The map unit name of the soil within the project area is Atkins-Ernest complex, 0 to 8 percent slopes (Ax). Ax is classified as a poorly drained and moderately well drained soil with slow to moderate permeability. According to the Bedford County Hydric Soils List, Ax is classified as a hydric soil. The National Wetlands Inventory (NWI) indicates that there are no wetlands within the project area, however, a field investigation indicates the presence of three wetland areas. The wetlands and their boundaries are shown on the Erosion and Sediment Pollution Control Plan. The map unit names of the soils and the limits of disturbance are shown on the Soils Map, included in this section. Following the Soils Map, Table I lists some soil characteristics for the soil found within the limits of disturbance. Following Table I is Table II which lists the limitations for roadway construction for the soil present at the site based on the information provided in the NRCS Website, http://soilmap.psu.edu.

102.4(b)(5)(iii) CHARACTERISTICS OF EARTH DISTURBANCE ACTIVITY This project involves the replacement of an existing structure on State Route 2007 in Monroe Township. Runoff from the site will discharge into Chapmans Run. Permanent structures such as rock outlet protection will be built at specified locations along the roadway. An existing swale disturbed during construction will be reconstructed to match existing conditions and will be immediately stabilized using jute matting or other stabilization measures approved by the Engineer. Also a temporary V-ditch will be replaced with 24” CMP immediately after the temporary road is removed. Temporary BMP’s will include compost filter socks, pumped water filter bags, and temporary seeding. No major roadway realignments are proposed for this project. Roadway reconstruction associated with the structure replacement is proposed between Station 784+75.00 to 786+19.00 and Station 786+43.00 to 787+87.00. A temporary roadway will be constructed downstream of the existing bridge. All disturbed areas will be provided with permanent seeding. 102.4(b)(5)(iv) RUNOFF FROM PROJECT AREA AND ITS UPSTREAM WATERSHED This project begins approximately 1.5 miles southeast from the Village of Clearville along State Route 2007 and extends for approximately 325 feet or 0.061 miles. Runoff from the project drains overland into Chapmans Run, which is a tributary to Shaffer Creek. Sediment laden runoff will be treated with compost filter socks. 5/6/2008

SECTION 804—SEEDING AND SOIL SUPPLEMENTS
804.1 DESCRIPTION—This work is furnishing and placing of seed and soil supplements of the type indicated, the application of herbicides, and mowing requirements.
The following definitions apply:
(a) Certified Seed. Seed of known genetic identity that has been field and laboratory inspected and tested during its period of growth to provide a source of high quality seed and ensure genetic identity and purity. Seeds are certified by recognized certifying agencies that conform to the certification laws and regulations of Pennsylvania or other states. Certification identification is indicated on all seed lot tags or labels.
(b) Germination. The emergence and development from the seed embryo of essential plant structures that can produce a normal plant under favorable conditions and is represented by a percentage of an identified seed quantity exclusive of hardseed.
(c) Hardseed. Unscarified seed that remains hard or has not germinated at the end of a prescribed test period because the seed has not absorbed water due to an impermeable seed coat.
(d) Pure Live Seed (PLS). A term that defines the planting quality of seed exclusive of inert matter and all other seeds not of the seed type being analyzed as determined by inspection and testing regulations. PLS is often used where seed industry standards have not been established for minimum acceptable purity and germination limits.
(e) Purity. The genetic identity of a seed that will produce a known plant and is represented by a percentage of an identified seed quantity or seed lot.
(f) Seed Formula. A seed mixture of more than one variety of a seed kind in excess of 5% by weight of the whole.
(g) Seed Lot. A definite quantity of seed identified by an assigned number or mark and is uniform throughout for all seed quality factors stated on the lot label or are within permitted tolerances.
(h) Seed Mixture. A seed batch that consists of more than one kind of seed when each kind is present in excess of 5% of the whole.
(i) Variety. A plant kind subdivision that can be differentiated from other plants of the same kind by growth, yield, fruit, color, seed, or other identifying characteristics.
(j) Weed Seed. Seed producing plant generally recognized as a weed by the Pennsylvania Department of Agriculture and includes the seed of prohibited and restricted noxious weeds.

(b) Seed.
1. General. Seed conforming to the regulations of Chapter 71 – Seed of the Pennsylvania Seed Act 164 of 2004, effective January 29, 2005, and amendments. Meet other applicable regulations of the Seed, Testing and Certification Programs of the Pennsylvania Department of Agriculture (PDA), Bureau of Plant Industry. Provide seeds that have been tested and approved for the specified seed formula’s purity, germination, and weed seed analysis limits and other applicable PDA rules for seed testing. Provide certified seed for all Kentucky Bluegrass, Perennial Ryegrass, Creeping Red Fescue, Chewings Fescue, Hard Fescue, and Birdsfoot Trefoil varieties submitted for each seed formula. Provide certified Penngift Crownvetch seed for Formula C.
804.2(b) 804.2(f)
804 - 3 Change No. 3
Provide pemixed seed mixtures from a licensed seed distributor/seed mixing company located within the State and mixed under the supervision of the PDA for the designated Table A seed formulas. Use only seed that has an approved seed inspector’s tag or label signed by a PDA inspector sewn or stapled to the outside of each seed bag or other container in a conspicuous place. Pressure sensitive labels may be used on paper or plastic containers. Seed mixtures may also be mixed to project specifications at the project site for special seed formulas or mixtures not specified in Table A, if all specified seed species have been previously inspected, tested, and approved by PDA for the designated purity, germination, weed seed limits, or pure live seed analysis. Mix the seed species to the designated formula or mixture specifications under Department supervision. Do not use seed from containers that have not been properly sealed. Do not use seed that has a sell-by date of more than 15 months from the date of the inspection test, exclusive of the month of the test. The Department may reject or request re-testing for any questionable seed delivered to the project.
2. Standard Seed Formulas. See Table A.
3. Special Seed Formulas and Pure Live Seed. Seed for special seed formulas consisting mainly of warm-season grasses, forbs, or wildflowers may be required to be provided in quantities based on specified pure live seed application rates. Application rates for the special seed formulas may vary. The PLS seed application rate is a method of adjusting the amount of seed required to compensate for low seed purity and low germination percentages. The normal amount of seed to be provided for each seed type is higher and based on each seed’s PLS analysis. Provide PLS seed calculation amounts based on the seed label for all designated PLS seed formula types for verification and approval before application. The specified PLS seeding rate for each seed type divided by the percentage PLS value of the proposed seed type will determine the amount of seed required to be provided for that seed type. Note: Seed with a purity of 85% and 70% germination rate would equal a PLS of 60% (85% x 70% divided by 100). A specified rate of 2.8 kg/hectare (2.5 pounds/acre) of PLS seed would therefore require 4.7 kg (4.2 pounds) quantity of seed to be provided for that seed type.
(c) Inoculant. Standard acceptable commercial product, for treating leguminous seed. A product consisting of a suitable carrier, containing a culture of nitrogen-fixing bacteria specific for the seed to be inoculated. Keep lids on containers when not in use to avoid contamination. Store containers at moderate temperature. Do not use inoculant after the expiration date shown on the container.
(d) Herbicides. Conforming to all applicable Federal and State pesticide acts and registration requirements and as specified in PCID No. 1094 – Herbicides (Weed and Brush Control) issued by the Pennsylvania Department of General Services, Bureau of Purchases, Quality Assurance Division, for the appropriate type. Furnish herbicide in manufacturer’s labeled container as follows:
1. Selective Control in Seeded Areas. In areas seeded with Formula B or D, use Type 1, Class C-2, 4-D Liquid Amine Salt Formulations (Dimethylamine) listed in PCID No. 1094, for controlling broadleaf weeds.
(e) Mow-Line Delineator Stakes. Not used.

Extend seeding dates where project conditions warrant. Apply full treatment or apply only 50% of the permanent seeding and soil supplements and apply the remaining 50% within the next seeding dates, as directed in writing. Use tillage and soil supplements before permanent seeding on topsoiled areas, where temporary seeding or mulching has been applied. The Contractor may apply permanent seed and/or soil supplements without tilling on untopsoiled areas, where temporary seeding or mulching has been applied.
(b) Tillage. On topsoiled areas, 1:3 (3:1) and flatter, loosen the surface to a depth of at least 50 mm (2 inches) by disking, harrowing, or other acceptable methods until the tillage is satisfactory. On untopsoiled areas, 1:3 (3:1) and flatter, till only as directed. Also, till or scarify areas if the surface is glazed or crusted. Correct surface irregularities by filling depressions and leveling rough or uneven areas. Remove metal objects, stones larger than 50 mm (2 inches) in any dimension, and other debris or objects deemed detrimental to maintenance operations.
(c) Soil Supplements. Prepare areas for seeding by uniformly applying supplements, except in areas that will receive Formula E seed. Document bulk delivery as specified in Section 804.2(a)2. Blend the initial soil supplements into the soil at least 50 mm (2 inches), on topsoiled areas, by raking, disking, harrowing, or other acceptable methods. Blend the supplements into the soil during tillage operations. Apply slow-release nitrogen fertilizer to the surface of Formula B, D, L, and W seeded areas before project completion. Do not apply slow-release nitrogen fertilizer supplement to Formula C seeded areas. Apply soil supplements as follows, unless otherwise indicated:
• Pulverized Agricultural Limestone — 435 kg/1000 m2
(800 lb/1000 yd2)
• 10-20-20 Analysis Commercial Fertilizer — 80 kg/1000 m2

(d) Inoculating Legumes. Inoculate leguminous seed, such as Crownvetch and Birdsfoot Trefoil, with proper cultures, according to the manufacturer’s directions. Protect inoculated seed from prolonged exposure to sunlight before sowing. Reinoculate seed not sown within 24 hours. If using hydraulic seeders, use inoculant four times the manufacturer’s recommended rate. If inoculated seed is held in a slurry with fertilizers for more than 1 hour, reinoculate or apply legumes separately.
(e) Seeding. At the rates specified in Table A, sow seeds uniformly on the prepared areas by the helicopter, hydraulic placement, broadcasting, drilling, or hand seeding methods. Inspect seeding equipment and adjust the equipment, if required, to ensure the specified application rates. Periodically perform a check on the rate and uniformity of application, as directed. Prior to seed application of each designated seed formula, thoroughly clean-out seed tank by rinsing with clean water to prevent contamination from one seed formula to the next. Repeat rinsing cycle until tank is clean. Collect all non-applied seed derived from each clean-out event and remove as waste from the project.
(f) Rolling. After seeding, roll topsoiled areas that are to be mowed. Use a roller with a mass (weight) not more than 100 kg/m (65 pounds per foot). If soil is wet or frozen, roll only when directed.
(g) Mow-Line Delineation. Not used.
(h) Herbicides. Apply herbicides as directed, to areas that are to be mowed and where weed growth is prominent. The Representative will designate existing plants or groups of plants to be saved within these areas before herbicide application. If directed, more than one application may be required to control undesirable growth. Apply material with application personnel certified by the Department of Agriculture and with equipment specified in Section 108.05(c).
(i) Liability and Rejection. Final acceptance of seeding and soil supplement materials and installation are subject to the results of official sampling and testing as specified before use and installation and the resultant establishment of the specified vegetation. Remove non-approved materials from the project.
1. Liability. Reseed rejected areas with additional applications of the specified seed and soil supplement materials. Redress soil surfaces when directed. Perform reapplication of seed and soil supplements within the next applicable seeding date if necessary or as directed. When directed, reseed areas damaged by herbicide applications and mowing operations. NOTE: Reseeded areas will also require the application of appropriate mulch as specified in Section 805.
2. Rejection Criteria. Seeded areas may be rejected based on the lack of actual grass seedling establishment exhibited in the area for the specified seed formula.
2.a Table A Seed Formulas. Table A formula seeded areas that exhibit less than 70% surface area coverage with the specified germinated grass seedlings after 90 days of growth may be rejected upon visual inspection. The seed germination and growth period is determined from the date of the seeding operation for the area when these operations are performed within the specified seeding dates.
2.b Special Seed Formulas. Special seed formula planted areas (seed mixtures not indicated in Table A) may be rejected based on the lack of the specified seed germination and growth of less than 11 seedlings/m2 (9 seedlings/square yard) after 120 days of growth determined by visual inspection. The seed germination and growth period is determined from the date of the seeding operation of the area when these operations are performed within the specified seeding dates.
2.c Eroded Areas. Seeded areas exhibiting soil surface erosion rills or gullies deeper than 250 mm (1-inch) may be rejected upon visual inspection. Redress and reseed designated eroded areas with specified materials and application rates as directed.

(j) Maintenance. Maintain grass and legume ground cover areas, within the grading limits, until the entire project has been completed. Mow as specified in Section 804.3(k). Control any noxious weed growth found within the right of way, by herbicide spraying and cutting. These plants are defined by the Pennsylvania Weed Control Act of 1982, P.L. 228, No. 74 and as amended by further legislation. Submit, for approval, a schedule of work and list of herbicide material to be used before starting this operation. If a slope failure occurs on a slope previously completed, and requires further excavation and redressing to reestablish the slope, reapply the seeding and soil supplement work as specified for the original slope.
(k) Mowing. Maintain turf grass areas within the grading limits, by mowing with approved equipment until the entire project has been completed. Submit a proposed schedule of mowing operations that covers the length of the construction project for approval.
1. Roadside Turf Areas. Turf grass areas established with Formula D requires a different degree of mowing maintenance than areas established with Formulas B and L. Three mowing cycles per year, scheduled between April and October, are anticipated for mowing areas seeded with Formula D. The number of cycles may be adjusted based on the degree of turf establishment, project length, weather conditions, or other factors. Consult the District Roadside Manager for schedule, safety requirements, and mowing equipment approvals. Schedule the first mowing cycle early in the growth flush period before all seed heads have emerged. Schedule the second mowing approximately 3 to 4 weeks after the first cut to remove the remaining seed heads. Schedule the last mowing cycle in the fall, as directed. Do not mow grass shorter than 100 mm (4 inches) to allow a low growing, competitive ground cover. Do not mow under the following conditions:
• When soil and grass blades are wet.
• During drought conditions, or during summer months when the temperatures are consistently over 32 ºC (90F), and when the grass exhibits dormancy.
• Within 7 days of any scheduled herbicide application or 7 days after a herbicide treatment.
2. Lawn Turf Areas. Maintain Formula B and L turf grass areas at a desired height of 50 mm (2 inches). Initiate mowing operations when grass seedlings reach a height of 75 mm (3 inches). Continue mowing operations during the active growing season throughout the length of the project. Follow the non-mow requirements indicated for Formula D grass. Mow at a normal frequency when the grass reaches the 75 mm (3-inch) height, unless directed otherwise.
