5. Additional erosion and sedimentation control design standards and criteria that must be applied where infiltration BMPs are proposed 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).

6. 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. Removal of silt and debris from basins, traps, inlet protection, silt fencing, or other structures or measures when capacity of those structures is reached.

C. Establishment or reestablishment of vegetation by seeding and mulching or sodding of scoured areas or areas where vegetation has not successfully been established.

D. Installation of necessary controls to correct unforeseen problems caused by storm events within design frequencies.

E. The contractor or developer shall be responsible for removal of all temporary measures and installation of permanent measures upon completion of the project.

§ 19-402 Total Maximum Daily Load (TMDL) Requirements.

1. Agricultural activities contributory to a watershed within Susquehanna Township containing an established nonpoint source (agricultural) TMDL, shall be conducted in compliance with Chapter 102 (Erosion and Sediment Pollution Control), Chapter 91, § 91.36 (General Provisions related to Manure Management), and Act 38 (Nutrient Management).
