PROJECTS

SCOTT RUN WATERSHED RESTORATION (ERIE COUNTY, PA)

Specific Tasks for the Project included the following:

 

  • Conduct feasibility assessment, landowner outreach

  • Complete detailed site assessment and preliminary design

  • Prepare final designs and cost estimates for restoration plan

  • Obtain permits

PROJECT SYNOPSIS

 

Scott Run is included in the Pennsylvania 303(d) list due to impairment of aquatic life by siltation. High particulate loads occur during erosional events caused by peak flow conditions in the channel and mass wasting of its banks. This sediment is transported downstream and ultimately into Presque Isle Bay. The project will reduce sediment pollution (aka siltation) in Scott Run by (1) improving the management of surface water in adjacent upland areas and (2) stabilizing the incised channel and banks.

 

PROJECT OUTCOME

 

Project deliverable includes a permitted Best Management Practices (BMP) restoration plan and estimate of construction costs for surface water management and channel stabilization. Project construction is dependent on future funding.

FORMER GASOLINE STATION (ALLEGHENY COUNTY, PA)

Specific Tasks for the Project included the following:

 

  • Secure full reimbursement of investigation and remediation costs from PA USTIF

  • Complete excavation of highly impacted soils

  • Conduct soil and groundwater characterization

  • Perform hydrogeological aquifer characterization

  • Conduct ecological and health-based risk assessment

  • Evaluate remedial measures specific to the site

  • Complete in-situ treatment (chemical injection) of petroleum impacted soils

  • Fate & transport evaluation

  • Develop Site-Specific Standard for groundwater contamination

  • Prepare and submit Remedial Investigation Report (RIR) and Final Report to PADEP

PROJECT SYNOPSIS

 

ER&R conducted an extensive site characterization following identification of a release of VOCs to soil and groundwater. The work included attainment of the site specific standards under Act 2 from former USTs. The site development consisted of the removal and replacement of over 750,000 cubic yards of fill material.

 

PROJECT OUTCOME

 

ER&R remediated the site using a combination of remediation technologies to achieve the site-specific cleanup standard. The site received an Act 2 relief of environmental liability for identified petroleum constituents and the site was redeveloped as a multi-facility automotive dealership.

FORMER LANDFILL SITE - (ERIE COUNTY, PA)

PROJECT SYNOPSIS

 

The site is a former 35 acre landfill redeveloped as a golf course and was under consideration for purchase by a municipality. ER&R characterized the site, removed drums, tires and wastes at surface, and addressed groundwater under the Statewide health standards and wastes in accordance with the approved cleanup plan.

 

PROJECT OUTCOME

 

ER&R assisted with the division of technical responsibility for the “buyer-seller” agreement. The property was successfully purchased and continues to operate as a golf course.

Specific Tasks for the Project included the following:

 

  • Completion of test pits, soil borings, and monitoring wells

  • Stream sampling

  • Development of Site-Specific Standard for a naturally occurring metal

  • Preparation of Work Plan and Remedial Investigation Report

  • Excavation and removal of debris and historic fill at surface

  • Prepared and implemented Cleanup Plan

  • Placement of a minimum of 2 to 4 feet of soil as a cap over fill material, grading and revegetation

  • Two years of quarterly groundwater monitoring

  • Liaison with state regulators on behalf of buyer and seller

  • Prepared Post Remediation Care Plan

  • Assist Attorneys with Preparation of Environmental Covenant for final transfer

  • Prepared Final Report and received Act 2 relief of liability for all parties

WALNUT CREEK WATERSHED RIPARIAN BUFFER (ERIE COUNTY, PA)

Specific Tasks for the Project included the following:

 

  • Site inspections to delineate soil types, hydrologic conditions, and native plant species

  • Preparation of site plans to ensure species selection and placement are compatible with site specific characteristics

  • Installation of native species

  • Assessment of planting success

  • Liaison with client and local stakeholders

PROJECT SYNOPSIS

 

ER&R installed more than 200 native trees and shrubs at three sites in Erie County, Pennsylvania, to help restore portions of the Walnut Creek riparian buffer. This work was conducted under contract with Pennsylvania Sea Grant and completed by staff associated with our new Division of Coastal Zone and Watershed Management.

 

PROJECT OUTCOME

 

Six months after installation, ER&R inspected each site to assess success. Our results indicate more than 97% of the plants had survived and now contribute to the natural biodiversity and habitat function of the Walnut Creek riparian buffer.

RESIDUAL WASTE FLUID RELEASE

PROJECT SYNOPSIS

 

A production fluid release was identified at an active well pad operated by an oil & gas producer. Immediate implementation of corporate spill response procedures was effective in controlling a potentially catastrophic release. The producer retained ER&R to conduct a complete site characterization of soil and groundwater proximate to the site. The characterization was initiated within 48 hours of the confirmed release.

 

PROJECT OUTCOME

 

ER&R directed the characterization and remediation work in accordance with the PADEP draft oil and gas spill policy. Results of the activities were compiled and submitted to PADEP the form of a Final Report. The Report demonstrated attainment of the Statewide health standard medium-specific concentrations (SHS MSCs) (residential used aquifer) and requested relief of environmental liability, specific to this incident, for the remediator and the property owner.

Specific Tasks for the Project included the following:

 

  • Emergency site response, evaluation and coordination

  • Site reconnaissance and sensitive receptor evaluation

  • Preparation of site characterization work plan

  • Installation of numerous soil borings, monitoring wells and bedrock water wells

  • Completion of extensive potable water well, groundwater and surface water sampling plan

  • Source removal oversight during remediation

  • Hydrogeological and aquifer evaluation

  • Liaison with state environmental regulators

  • Completion and submittal of Final Report within 90 days demonstrating attainment of SHS MSCs
