- Pipeline Maintenance & Repair
Our team was retained to provide environmental permitting and construction monitoring services the P-40 project. Services included stream and wetland surveys and permitting, threatened and endangered species review, stormwater permitting and environmental monitoring for construction compliance.
The project was an active 100-mile pipeline repair project spanning six counties; Burns & McDonnell came aboard during construction. Enterprise sought guidance in navigating active permits on the project and assistance in developing a path forward for permit modifications and the monitoring necessary to complete construction and permit close out.
Our efforts began with an in-depth review of the active permits, including an Erosion and Sediment Control Construction General Permit (ESCGP-2) for the entire project right-of-way (ROW), consisting of 33 discrete dig locations. The project was also permitted under county-specific Water Obstruction and Encroachment Permits (WOEPs) for impacted stream and wetland features within the project ROW.
As required by the ESCGP-2, weekly monitoring for vegetation restoration was initiated at the onset of thawing ground at 19 discrete dig locations and their associated access routes. Weekly inspection reports were completed using the Pennsylvania Department of Environmental Protection (PA DEP) Visual Site Inspection Report and maintained with the Erosion and Sediment Control Plan. The nature of the project required continuous coordination with each respective county conservation districts for site closure and final inspection.
In 2015, 19 sites were completed, requiring continued monitoring for vegetative restoration; 14 sites were slated for constructed in 2016. Revised access routes were proposed for several of these sites, which required minor permit amendments under the WOEP and ESCGP-2 for earth disturbance activities and additional stream crossing and temporary wetland impacts. For these additional locations, a wetlands team was deployed to perform wetland and stream delineations of the proposed routes. The findings of these delineations, along with GIS analysis, Pennsylvania Natural Diversity Inventory (PNDI) submittals, and coordination with multiple state and county agencies were submitted to PA DEP for permit amendment.
Weekly environmental monitoring for construction compliance began in 2016, at the onset of construction on the 14 new sites, and vegetation restoration monitoring will continue into 2017. As required by the WOEPs, one year of monitoring will be conducted on all wetlands affected. The wetland team will be deployed to perform a final site delineation and a monitoring report will be submitted to PA DEP.
