ESI developed environmental plans and provided supporting environmental studies along a 55-mile natural gas pipeline corridor and associated access roads in Pennsylvania.
Services included:
- Engineering Plans and Permitting: prepared Erosion and Sedimentation Pollution Control plans and drawings, developed post-construction Stormwater Management Plan, designed permanent stormwater management controls, and prepared subsequently approved phased ESCGP-2 permit. Prepared IFB and IFC production sets, quantity take-offs, township grading permits, and provided environmental construction support
- Aquatic Resources: delineated aquatic resources; prepared and submitted results in accordance with PADEP Chapter 105 and USACE SPGP-4 permit processes. Prepared other related permits involving temporary road crossings, hydrostatic discharge, and Section 10 authorization for HDD beneath the Ohio River
- Section 7 Endangered Species Act Compliance: completed surveys for bats, birds, and plants. Prepared Bat Conservation Plan and Migratory Bird Protection and Enhancement Plan
- Section 106 Cultural Resources Compliance: conducted field surveys and coordination with Pennsylvania Historic and Museum Commission and U.S. Army Corps of Engineers
- Natural Resource Restoration Plans: completed re-delineation and assessment for over 280 streams and over 200 wetlands proximate the project to assess whether or not construction impacted resources via sediment, slope failure, or through construction practices. Sedimentation analysis was completed for each stream and the immediately downstream water body. Aquatic restoration plans were developed for 16 streams and 23 wetlands significantly impacted by pipeline construction along the project corridor
- Compliance Order Permitting: Upon issuance of multiple compliance orders by the Pennsylvania Department of Environmental Protection (PADEP), a construction shutdown occurred. A fully updated Erosion and Sedimentation Pollution Control plan, stormwater management plan, and permit amendment were required within a 90-day time period. Required submittals included a full re-delineation of all aquatic resources, a plan set establishing all slope failures and vegetative cover assessments of the limits of disturbance, a temporary stabilization plan for the right-of-way (including geotechnical remediations for slope failure areas), and an assessment of existing erosion control BMPs and their efficacy. ESI performed as the engineer of record and obtained conditional approval from the PADEP to resume construction.
