ALDOT CBMPP Version December 2016
CBMPP Explanation This ALDOT Construction Best Management Practices Plan (CBMPP) is intended to satisfy the requirements of the Alabama Department of Environmental Management (ADEM) Administrative Code and the National Pollutant Discharge Elimination System (NPDES) Construction General Permit. This CBMPP is also a means to gather and communicate environmental concerns, commitments, and contract requirements to ALDOT design and construction personnel as well as Contractors. This document, all referenced or attached documents, and those posted on the Electronic CBMPP webpage together constitute the CBMPP for this project. This CBMPP is provided to ALDOT Contractors prior to project letting. The CBMPP is comprised of two main components; a Design Component and an Operational Component. The Design Component is created and updated during the planning and design phase by ALDOT and/or consultant design personnel. The Design Qualified Credentialed Professional (QCP) certifies the Design Component of the CBMPP as having addressed all known environmental concerns, and that these concerns have been addressed in the project design. The Operational Component is created and updated during the construction phase by ALDOT project personnel and contractor personnel. The Operational Qualified Credentialed Professional (QCP) certifies that the Design Component will be adhered to as closely as possible, and that the Operational Component will be created, updated, and adhered to during construction of the project. This CBMPP is to be maintained at the Project Office during active construction on the project and retained with the project records after project completion. The CBMPP is to be made available to all project staff including all Contractors, ALDOT staff, and Regulators.
