SPECIFICATIONS: The Department recommends the use of the Penn State publication, "Erosion Control and Conservation Plantings on Noncropland," as the standard to use for the selection of species, seed specifications, mixtures, liming and fertilizing, time of seeding, and seeding methods. Specifications for these items may also be obtained from PennDOT's Publication # 408, Section 804 or by contacting the applicable county conservation district. Upon selection of a reference, that reference should be used to provide all specifications for seeding, mulching, and soil amendments. The following specification will be used for this project:

STABILIZATION METHODS AND STANDARDS (Continued)

· SEEDING

Seed mixtures shall comply with Standard E&S Worksheet #21. Seeding rates are stated as pounds per acre (lb/A) of pure live seed (PLS). PLS is the product of the percentage of pure seed times the percentage of germination divided by 100 (e.g. [85% pure seed 72% germination] ÷ 100 = 61% PLS). Seed should not be used later than one year after the test date that appears on the label. Use of seed older than one year could result in less than satisfactory vegetative coverage and the need to re-seed the disturbed area. Actual seeding rates may be determined by dividing the PLS seeding rate by the %PLS shown on the seed tag, or calculated as shown above (e.g. for a PLS seeding rate of 12 lb/A from a seed lot with a PLS of 35%, the actual seeding rate is equal to 12 ÷ 0.35 = 34.3 lb/A). If more than one species is used, indicate the application rate for each species. A nurse crop may be necessary if the selected species do not rapidly germinate. If a nurse crop is used in conjunction with permanent seeding, the nurse crop should not hinder the establishment of the permanent vegetation. A nurse crop should not be applied at a rate exceeding 50% of its temporary seeding rate.

The Department recommends that soil testing be done prior to seeding and mulching to determine the proper soil amendments and application rates for the proposed seed mixture(s). In the absence of a soil test, soil amendments should be added at the rates specified by the selected seeding reference.

Fill slopes should be seeded and mulched at regular vertical increments -- 15 to 25 feet maximum -- as the fill is being constructed. This will allow the bottom of the fill to progress toward stabilization while work continues on the upper portion, making final stabilization easier to achieve and providing some vegetative buffering at the bottom of the slope.

Wherever seed and mulch is applied by hydroseeding methods, the seed and mulch should be applied in separate applications with the seed being applied first and the mulch sprayed on top of the seed. This is to ensure that the seed makes contact with the underlying soil. Soil preparation should be completed prior to adding seed to the hydroseeding equipment. Running seed through the pumping system can result in excessive abrasion of the seed and reduce the percentage of pure live seed in the application. Therefore all site preparation should be completed prior to the arrival of the hydroseeder.

In critical areas (e.g. adjacent to or within 50 feet of streams, ponds, or wetlands) a protective blanket should be provided for all seeded areas. Consideration should be given to use of mulch with netting or protective blankets for all seeded areas on slopes 3H:1V or steeper.

Vehicular traffic should be restricted from areas to be seeded to prevent soil compaction.

· TOPSOIL APPLICATION

Graded areas should be scarified or otherwise loosened to a depth of 3 to 5 inches to permit bonding of the topsoil to the surface areas and to provide a roughened surface to prevent topsoil from sliding down slope.

Topsoil should be uniformly distributed across the disturbed area to a depth of 4 to 8 inches minimum -- 2 inches on fill outslopes. Spreading should be done in such a manner that sodding or seeding can proceed with a minimum of additional preparation or tillage. Irregularities in the surface resulting from topsoil placement should be corrected in order to prevent formation of depressions unless such depressions are part of the PCSM plan.

Topsoil should not be placed while the topsoil or subsoil is in a frozen or muddy condition, when the subsoil is excessively wet, or in a condition that may otherwise be detrimental to proper grading and seedbed preparation.

Compacted soils should be scarified 6 to 12 inches along contour wherever possible prior to seeding.

· SPILL CONTROL

Spill control procedures are implemented anytime chemicals and/or hazardous substances are stored or used at the construction site. Substances include, but are not limited to fuel, lubricants, hydraulic fluids, coolants, paint, etc.

The spillage should be stopped as soon as it can be done safely, and the cleaned up immediately. Clean contaminated area, and properly dispose of contaminated materials properly. For all spills, notify the project foreman. Use the following spill prevention and controls when applicable:

· To the extent that it doesn't compromise clean-up activities, spills shall be covered and protected from stormwater run-on during rainfall,

· Spills shall not be buried or diluted with wash water,

· Used clean up materials, contaminated materials, and recovered spill material shall be stored and disposed of in accordance with federal, state and local regulations,

· Use absorbent materials on spills, rather than using water to hose down the spill,

· When water is used for cleaning and decontamination of a spill, the water shall not be allowed to enter stormwater conveyance or watercourses, and shall be collected and disposed of properly,

· All spill contaminated soil will be removed and disposed of properly,

· The condition of hydraulic equipment shall be visually assessed for potential leaks prior to use in the immediate vicinity approx. 25 feet of Swale.

· MULCHING

All seeded areas should be mulched or blanketed to minimize the potential for failure to establish an adequate vegetative cover. Mulching may also be used as a temporary stabilization of some disturbed areas in non-germinating seasons. Mulches should be applied at the rates shown in Table 11.6 (Appendix).

Straw and hay mulch should be anchored or tackified immediately after application to prevent being windblown. A tractor-drawn implement may be used to "crimp" the straw or hay into the soil -- about 3 inches. This method should be limited to slopes no steeper than 3H:1V. The machinery should be operated on the contour. Note: Crimping of hay or straw by running over it with tracked machinery is not recommended.

Polymeric and gum tackifiers mixed and applied according to manufacturer's recommendations may be used to tack mulch. Avoid application during rain and on windy days. A 24-hour curing period and a soil temperature higher than 45 F. are typically required. Application should generally be heaviest at edges of seeded areas and at crests of ridges and banks to prevent loss by wind. The remainder of the area should have binder applied uniformly. Binders may be applied after mulch is spread or sprayed into the mulch as it is being blown onto the soil. Applying straw and binder together is generally more effective. Synthetic binders, or chemical binders, may be used as recommended by the manufacturer to anchor mulch provided sufficient documentation is provided to show they are non-toxic to native plant and animal species.

Mulch on slopes of 8% or steeper should be held in place with netting. Lightweight plastic, fiber, or paper nets may be stapled over the mulch according to manufacturer's recommendations.

Shredded paper hydromulch should not be used on slopes steeper than 5%. Wood fiber hydromulch may be applied on steeper slopes provided a tackifier is used. The application rate for any hydromulch should be 2,000 lb/acre at a minimum.

E&SCP GENERAL NOTES (Continued)

· Immediately after earth disturbance activities cease in any area or subarea of the project, the operator shall stabilize all disturbed areas. During non-germinating months, mulch or protective blanketing shall be applied as described in the plan. Areas not at finished grade, which will be reactivated within 1 year, may be stabilized in accordance with the temporary stabilization specifications. Those areas which will not be reactivated within 1 year shall be stabilized in accordance with the permanent stabilization specifications.

· Permanent stabilization is defined as a minimum uniform, perennial 70% vegetative cover or other permanent non-vegetative cover with a density sufficient to resist accelerated erosion. Cut and fill slopes shall be capable of resisting failure due to slumping, sliding, or other movements.

· E&S BMPs shall remain functional as such until all areas tributary to them are permanently stabilized or until they are replaced by another BMP approved by the local conservation district or the Department.

· Upon completion of all earth disturbance activities and permanent stabilization of all disturbed areas, the owner and/or operator shall contact the local conservation district for an inspection prior to removal/conversion of the E&S BMPs.

· After final site stabilization has been achieved, temporary erosion and sediment BMPs must be removed or converted to permanent post construction stormwater management BMPs. Areas disturbed during removal or conversion of the BMPs shall be stabilized immediately. In order to ensure rapid revegetation of disturbed areas, such removal/conversions are to be done only during the germinating season.

· Upon completion of all earth disturbance activities and permanent stabilization of all disturbed areas, the owner and/or operator shall contact the local conservation district to schedule a final inspection.

STABILIZATION METHODS AND STANDARDS

· GENERAL

As soon as slopes, channels, ditches, and other disturbed areas reach final grade they must be stabilized. Upon completion or temporary cessation of the earth disturbance activity in a special protection watershed, that portion of the project site tributary to the special protection waters must be immediately stabilized. In all other watersheds, cessation of activity for at least 4 days requires temporary stabilization.

Keeping stabilization current with earthmoving is recommended for all projects, regardless of watershed classification. This chapter is intended to provide guidance and specifications for stabilization as well as information that is useful in achieving stabilization in the least amount of time.

· VEGETATIVE STABILIZATION

All disturbed areas that have not otherwise been stabilized and have significant potential for erosion should be stabilized with vegetation. This includes graded areas where it is anticipated that future earthmoving will take place within the coming year. Areas that will be subject to earthmoving within 12 months may be stabilized with temporary seed mixtures, predominantly annual grasses. All others should be stabilized with permanent seed mixtures -- predominantly perennial grasses. When final grade is achieved during non-germinating months, the area should be mulched until the beginning of the next planting season. However, the area will not be considered stabilized until a minimum uniform 70% vegetative cover of erosion resistant perennial species has been achieved. Critical areas --erodible soils, within 50 feet of a surface water, etc. -- should be blanketed.

Temporary erosion control BMPs that were installed for the earthmoving phase of the project must remain in place and be maintained in working order until permanent stabilization is achieved.

NOTE: Areas that do not receive sufficient sunlight to support vegetation (e.g.

under bridge decks) should be stabilized by some means other than vegetation.

As disturbed areas within a project approach final grade, preparations should be made for seeding and mulching to begin (i.e. anticipate the completion date and schedule the seeder).
