The PA Pipeline Project (PPP)/Mariner East II is an expansion of the existing Sunoco Mariner East pipeline system. Sunoco recently upgraded its existing Mariner East I pipeline to transport natural gas liquids from Ohio and the Pittsburgh area to its Marcus Hook Facility in Delaware County. More than 80% of the PPP will follow the same pipeline corridor as Mariner East I. The pipeline will traverse 17 counties in the southern tier of Pennsylvania.

On January 19, 2022, DEP received an amendment request to support the dewatering of sediment dredged from a predetermined area of Marsh Creek Lake, as required under the terms of the Consent Order and Agreement entered into between the DEP, DCNR, and Sunoco dated December 6, 2021 at HDD S3-0290, Upper Uwchlan Township, Chester County.
An increase to the limits of disturbance (LOD) of 4.06 acres is being requested. This includes 1.37 acres of proposed bulk earthwork where areas will be topsoiled and graded for the purposes of installing the rock construction entrance, temporary construction road and the preparation of the SMA where the geotubes will be placed. The remaining 2.69 acres will be used for the temporary storage of materials, products or equipment associated dredging and dewatering activity and will not be topsoiled or graded. Utilization of these areas is not proposed to result in earth disturbance but will include erosion and sedimentation (E&S) controls and have been included as part of the LOD.
Information on opportunities to comment on these amendments can be found here.

On January 19, 2022, DEP received an amendment request to support the dewatering of sediment dredged from a predetermined area of Marsh Creek Lake, as required under the terms of the Consent Order and Agreement entered into between the DEP, DCNR, and Sunoco dated December 6, 2021 at HDD S3-0290, Upper Uwchlan Township, Chester County.
An increase to the limits of disturbance (LOD) of 4.06 acres is being requested. This includes 1.37 acres of proposed bulk earthwork where areas will be topsoiled and graded for the purposes of installing the rock construction entrance, temporary construction road and the preparation of the SMA where the geotubes will be placed. The remaining 2.69 acres will be used for the temporary storage of materials, products or equipment associated dredging and dewatering activity and will not be topsoiled or graded. Utilization of these areas is not proposed to result in earth disturbance but will include erosion and sedimentation (E&S) controls and have been included as part of the LOD.
