Construction Examples of short term commitments during construction include installing and maintaining sediment and erosion control measures as per the UPDES Storm Water General Permit for Construction Activities; avoiding existing wetlands near the construction site; following the “Invasive Weed Control� Special Provision; maintaining access to businesses during construction; providing an archeologist to monitor earthwork activities during construction; and following all conditions in environmental permits. Examples of long term commitments installed during construction and maintained afterward include creating and monitoring new wetland mitigation sites; permanent slope stabilization; wildlife fencing; storm water detention ponds; and noise walls. Following all conditions outlined in environmental permits is also a commitment. Unless otherwise indicated, it is the contractor’s responsibility to follow and fulfill permit requirements. There are several permits that may be necessary depending on project scope. Department of the Army Permits are necessary to discharge dredged or fill material into wetlands or other special aquatic sites such as mudflats and playas. This permit is also needed for doing more than minor alterations to streams. The Department of the Army Permit outlines general and special conditions that must be followed. This permit is included in project contract documents before the project is advertised for construction. A Stream Alteration Permit (PGP-40) is necessary to modify a natural stream channel. A natural stream channel is defined as a natural drainage feature with a defined bed and bank and an ordinary high water mark. Modification activities may include bridge crossings, bank stabilization, scour mitigation, rock spur installation, etc. Stream Alteration Permits have general conditions associated with every permit and special conditions that are project specific. These conditions must be followed during construction and are typically included in contract documents as a Special Provision. Contractors are required to submit a Fugitive Dust Emission Control Plan to the state Division of Air Quality for approval before construction. This plan will describe specific requirements for emission control and monitoring efforts throughout the construction phase of a project. Measures to control fugitive dust may include watering, covering trucks, mulching disturbed slopes, and planting vegetation.
