SECTION 01 57 13

PART 1 - GENERAL

1.01 SECTION DESCRIPTION

A. The Work of This Section Includes:

1. Contractor shall implement and maintain the Soil Erosion and Sediment Control Plan prepared for the Project and/or Work as shown on the Drawings and described in this Section.

2. Contractor shall carry out the construction operations in such a manner that soil erosion and resulting turbid stormwater runoff and sedimentation are minimized.

1.02 RELATED SECTIONS

A. Related Work Specified Elsewhere:

1. Section 32 92 00: Finish Grading, Seeding and Sodding

1.03 QUALITY ASSURANCE

A. Reference Standards:

1. Pennsylvania Department of Environmental Protection Soil Erosion and Sediment Pollution Control Manual.

2. Pennsylvania Department of Transportation Publication 408 Specifications

1.04 JOB CONDITIONS

A. The associated work activities include but are not limited to the following items:

1. Temporary and permanent measures will have to be undertaken before, during and after construction to control sediment from being carried onto adjoining properties and into swales or watercourses as a result of stormwater runoff.

2. The use of temporary control devices as shown on the Drawings and as described in these Specifications are for providing the trapping of sediment resulting from construction activities and to reduce the velocities of the temporary stormwater courses to minimize erosion.

3. The erosion and sediment control devices shall be inspected on a weekly basis and after every storm event and shall be maintained throughout the life of this project.

These shall include, but are not limited to, temporary sediment basins and traps, stabilized construction entrances, perimeter dikes, perimeter swales and silt fences, as shown on the Drawings or other measures that are required for the construction of the Project and/or Work.

4. Upon completion of the Project and/or Work, and stabilization of disturbed areas, the temporary control devices shall be removed by Contractor.

5. Soil erosion and sediment control practices shall be consistent with the procedures outlined in the latest edition of the "Soil Erosion and Sediment Pollution Control Manual", Commonwealth of Pennsylvania, Department of Environmental Protection.

2.01 MATERIALS

A. Silt Fence:

1. Section 865, PennDOT Publication 408 Specifications.

B. Super Silt Fence:

1. Fabric attached to chain link fence in accordance with the PADEP’s Erosion and

Sediment Pollution Control Program Manual.

C. Coarse Aggregate (Stabilized Construction Entrance)

1. AASHTO #1, Table C, Section 703.2, Publication 408 Specifications.

D. Inlet Protection Devices

1. Section 860, PennDOT Publication 408 Specifications.

E. Final Grading, Seeding and Sodding

PART 3 - EXECUTION

3.01 TEMPORARY CONTROL MEASURES

B. Utility Construction:

1. Install erosion and sediment control measures in accordance with the Drawings and sequence of construction as approved by the County Conservation District.

2. Excavated material resulting from the installation of the water service line, sewage force main & appurtenances and gravity sanitary sewer shall be completely surrounded by silt fence or completely covered with a plastic sheet during non-work periods.

3. The crossing of a creek or water course is covered in Section 33 05 29 of these

Specifications.

4. Limit the removal of natural ground cover to the minimum area required for construction within non-paved areas.

5. Perform temporary seeding and mulching immediately upon completion of earthmoving, within seasonal constraints, of disturbed areas which are not actively being regraded until final grading and stabilization can be accomplished. Temporary seeding is covered in Section 32 93 00.

6. Dewatering or pumping out of excavated areas directly into existing storm ditches or natural channels which causes silt deposition, turbidity and/or possible erosion of banks is prohibited. Contractor must make use of sediment traps, filters, or other methods acceptable to the Resident Project Representative.

3.02 PERMANENT CONTROL MEASURES

A. Sewage Pumping Station Site and Wastewater Treatment Plant Site:

01 57 13-3

1. Perform permanent seeding and mulching of any disturbed areas immediately following final grading within seasonal constraints. Seeding is covered in Section 32 93 00.

B. Utility Construction:

1. Perform permanent seeding and mulching of any disturbed areas immediately following final grading of any non-paved areas within seasonal constraints. Seeding is covered in Section 32 93 00.

3.03 FIELD MODIFICATIONS

A. Owner reserves the right to require modifications to any or all sediment control measures provided in order to establish proper soil erosion and sedimentation control. In addition, any measures recommended or required by the County Conservation District shall be promptly implemented.
