I-79 and SR-22 Missing Ramps

Balfour Beatty Infrastructure
Robinson Township, PA – 2005-2008 – $525,000

Scope of Work:
PennDOT was adding ramps to the major interchange that had not been included during the initial road construction. Neumeyer Environmental was contracted to perform several activities in support of this project including management of acid mine drainage, noise monitoring, and to provide miscellaneous environmental support.

It was anticipated based on the project design that mine seals would need to be breached as part of the construction. Discharge of the acid mine drainage was expected when this breach occurred that could affect the local environment and water courses. Neumeyer Environmental evaluated the site characteristics and installed a pump and treat system to manage the drainage. The system included a 450 linear foot ditch that included a dispersion system with a neutralizing agent to treat the drainage.

Neumeyer Environmental also performed noise monitoring during the non-standard work hour activities. The project was bounded by several residential neighborhoods that were subject to disturbance by the construction activities. Neumeyer Environmental established baseline noise levels and performed bi-weekly monitoring to ensure noise levels were maintained within acceptable limits.

Turnpike Interchange Construction

DCK Worldwide, LLC (Dick Corp)
Cranberry, PA – 2003 – $250,000

Scope of Work:
During construction of a new interchange to connect the Turnpike with I-79 and US-19, crews encountered several abandoned oil wells that could potentially contaminate groundwater. PADEP environmental regulations require that abandoned wells be properly terminated (plugged) including removal of all drilling equipment and debris.

Neumeyer Environmental used a mobile oil well drill rig and redrilled the wells to a depth of 2,000 feet. We removed the old casings above that elevation and plugged the abandoned drill casings to that depth to prevent potential groundwater contamination by crude oil.
