III.a. Project Specific Best Management Practices

Provide a narrative describing the project and all BMPs included to meet the permit requirements. The narrative should reference the erosion and sediment control plan sheets and any environmentally relevant project details, notes, or special provisions. It may be beneficial to provide sheet numbers when referencing the plan set. In addition to the project specific items, referencing applicable sections from the resources supplied in Section II.b may also be helpful.

The narrative should be concise and address the following items, if applicable:

•Project description/overview (scope of work) • Sequence of construction

o Phasing o Diversions

o Disturbed Acreage Limitations • Priority waters impacted

o Priority Water

o 303(d) Pollutants of Concern o TMDL Reduction Rates o Designer Reduction Goals

• BMPs included to minimize erosion and sediment loss during construction o Ditch Checks

o Perimeter Controls o Inlet protection o Slope protection o Sediment Basins

o Stabilized Construction Entrances o Soil Stabilization

• Additional BMPs provided in priority areas

o Flocculants - list applications and reference Section III.b. Note Individual SDS sheets will be included in the Contractors SWMP provided in Section IV.

All BMPs shall be installed as detailed in the 2022 ALDOT Special and Standard Drawings. All BMPs shall be implemented and maintained in accordance with the “2018 Alabama Handbook for Erosion, Sediment Control, and Stormwater Management on Construction Sites and Urban Areas.

Concrete washout, lay down, and maintenance areas will be determined by the contractor prior to construction and added to the field CBMPP (For additional information regarding Concrete Washout areas, see ALDOT Standard Specifications for Highway Construction, Section 107.22).

Offsite sediment will be removed as needed by the Contractor in accordance with ALDOT Construction Specifications (For
