A: Yes, permits are required. The contractor must obtain all necessary permits as specified in the plans and specifications.

2. What are the SWPPP requirements?

A: Submit a written erosion and sediment control plan 30 days prior to start of construction, including all necessary permits. Controls must be installed before work begins and cannot be modified without approval. If controls fail to function, you must take corrective action.

Erosion and sediment control plans and inspections are also listed in the SOW.

However, Section 648.06 says: Contractor may incorporate suitable streambed materials encountered during excavation if they meet gradation requirements. If insufficient material exists: You must furnish streambed simulation material in accordance with Section 705.08 and Tables 705 4 and 705 5.
