SYSTEMWIDE OPEN-END FOR MANAGEMENT SERVICES
PENNSYLVANIA TURNPIKE COMMISSION

Under this systemwide, open-end agreement for management services, A.D. Marble & Company is providing the Pennsylvania Turnpike Commission (PTC) with technical review of natural resource studies and NEPA documents for the Mon/Fayette and Southern Beltway projects. The Mon/Fayette project involves the construction of four independent, four-lane, limited access highways from Morgantown, West Virginia, to Pittsburgh, Pennsylvania. The Southern Beltway projects involve the construction of three separate, four-lane, limited access highways totaling 71 miles in the Pittsburgh area. This is the largest project the PTC has undertaken since the construction of the Northeast Extension.

A.D. Marble & Company is providing management recommendations to expedite environmental studies and preparation of NEPA documents. Our company is also managing the natural resource studies for each project. This involves participating in PAMHEP studies and wetland field views, organizing special agency meetings, and reviewing all technical data, files, and documents. The technical studies managed by our company include wetland delineations, functional assessments, impact analyses, mitigation site selection, aquatic invertebrate and fish surveys, water quality analyses, farmland assessments, threatened and endangered species surveys, and biodiversity studies.

A.D. Marble & Company, in conjunction with the PTC and its consultant, recently developed wetland functional assessment methodology to be used on the Southern Beltway projects. The work involved researching other functional assessment methods used throughout the country. The method to be used on the PTC projects is based upon the New England Corps of Engineers Corps Descriptive Method (CDM). The CDM was adapted by A.D. Marble & Company and the PTC, field tested, and presented to the agencies for their approval.

These projects have a high level of visibility and complexity as well as rigorous schedules. Consequently, A.D. Marble & Company has worked closely with other members of the management team to determine the effects of natural resource assessment strategies and outcomes on other task areas of the NEPA process.
