“Responsibility Matters” is one of five core values in the PA Turnpike’s strategic plan, which emphasizes that the organization embodies “diversity, integrity, and sustainability in all our practices.” Responsibility Matters inspires and guides the Engineering Department’s decision making concerning the PA Turnpike’s Municipal Separate Storm Sewer System (MS4) Permit and its commitment to preventing and reducing stormwater pollution in a sustainable manner. As part of this commitment, the Turnpike employs numerous strategies to reduce pollutants across the 552-mile system, meeting and exceeding regulatory mandates. The MS4 program’s vision and organizational structure has enabled the PA Turnpike to boost awareness about the importance of preventing stormwater pollution runoff, nurture interdepartmental communication, develop innovative solutions for stormwater management and compliance, and improve efficiency of its stormwater-management operations.
