2.
Evidence of any necessary plan or permit approval for earth disturbance activities from PADEP or the Dauphin County Conservation District (DCCD) must be provided to Susquehanna Township.
A.
When 5,000 square feet or more of earth disturbance activities are proposed, an Erosion and Sedimentation Control Plan must be submitted to DCCD and the Township in accordance with 25 Pa. Code § 102.4(b). In addition, a letter of adequacy from DCCD shall be provided to Susquehanna Township for the E&S Control Plan by the applicant.
3.
A copy of the approved E&S Control Plan and any other permit, as required by PADEP or the DCCD, shall be available at the project site at all times, if required under Chapter 102.
4.
Construction of temporary roadways (e.g., for utility construction, timber harvesting, etc.) shall comply with all applicable standards for erosion and sedimentation control and stream crossing regulations under 25 Pa. Code Chapters 102 and 105. The Erosion and Sedimentation Control Plan shall be submitted to the DCCD for approval and shall address the following, as applicable:
A.
Design of the roadway system, including haul roads, skid roads, landing areas, trails, and storage and staging areas.
B.
Runoff control structures (e.g., diversions, culverts, detention ponds, etc.).
C.
Stream crossing for both perennial and intermittent streams.
(1)
Careful consideration shall be taken when interacting or crossing ephemeral streams. Any alterations to the stream channel, shall be restored to existing conditions in order to maintain drainageway/natural flow path.
D.
Access to public roadways, including design of rock construction entrance for mud and debris control.
E.
A remediation plan for restoring the disturbed area through regrading, topsoil placement, reseeding, and other stabilization techniques, as required.
5.
Design Criteria for Erosion Control Facilities. All erosion control facilities shall be designed at a minimum to meet the design standards and specifications of the latest revision of the Erosion and Sediment Pollution Control Program Manual, published by PADEP.
6.
Construction Standards for Erosion Control Facilities. Construction standards for erosion control facilities shall be in accordance with the approved plans and accompanying specifications. The construction standards for erosion control facilities outlined in the latest revision of the E&S Pollution Control Program Manual published PADEP shall be considered the minimal acceptable standard. Controls shall be installed at initial stages of earthmoving and otherwise as outlined in the staging of earthmoving activities section of the Soil Erosion and Sediment Control Plan.
7.
Additional erosion and sedimentation control design standards and criteria that must be applied where infiltration BMPs are proposed to include the following:
A.
Areas proposed for infiltration BMPs shall be protected from sedimentation and compaction during the construction phase, as to maintain their maximum infiltration capacity.
B.
Infiltration BMPs shall be protected from receiving sediment-laden runoff.
C.
The source of protection for infiltration BMPs shall be identified (i.e., orange construction fence surrounding the perimeter of the BMP).
8.
Maintenance is an essential part of the functionality of an erosion control system. Maintenance during development of a project shall be the responsibility of the developer and/or landowner and shall include, but not be limited to:
A.
Maintenance during development of a project shall be the responsibility of the developer and/or landowner and shall usually include, but not be limited to:
(1)
Removal of silt and debris from basins, traps, inlet protection, silt fencing, or other structures or measures when capacity of those structures is reached.
(2)
Periodic maintenance of temporary control facilities such as replacement of straw bale dikes, straw filters, or similar structures.
(3)
Establishment or reestablishment of vegetation by seeding and mulching or sodding of scoured areas or areas where vegetation has not successfully been established.
(4)
Installation of necessary controls to correct unforeseen problems caused by storm events within design frequencies.
(5)
The contractor or developer shall be responsible for removal of all temporary measures and installation of permanent measures upon completion of the project.
B.
Prior to the dedication of facilities to the Township the following procedures shall be completed for approval of dedication:
(1)
Site is 70% uniformly stabilized with perennial vegetation as identified and outlined on the approved plans.
(2)
All infrastructure has been flushed or vacuumed, as applicable.
(3)
All infrastructure has been televised by the selected contractor of the developer or property owner. Televising video shall be provided to the Township to review prior to approval or acceptance of the infrastructure. Any deficiencies or defects discovered in the video shall be rectified prior to approval or acceptance of the infrastructure.
(4)
Removal of all erosion and sediment control devices, i.e., inlet filter bags, compost filter sock, rock construction entrance, etc.
(5)
All proposed erosion and sediment control facilities must be converted to final stormwater management facilities and be inspected by Township and or its assignees.
(6)
Stormwater management facilities must pass inspection. The facilities also must be 90% uniformly vegetated with identified plant selection located on the approved SWM Site Plan.
C.
After dedication of facilities to the Township, except in cases where agreements to the contrary have been previously executed, maintenance shall be the responsibility of the Township and shall include:
(1)
Mowing to maintain adequate stands of grass and to control weeds. Chemical weed control may be used if state and local regulations are met. Selection of seed mixtures should reflect the type of maintenance desired by the Township.
(2)
Removal of silt from all permanent structures which trap silt or sediment is essential to keep this material from building up in grassed waterways and reducing their capacity.
(3)
It shall be the responsibility of the Township to inspect all permanent facilities and to see that corrective action is taken where necessary.
