SWPPP (Storm Water Pollution Prevention Plan)
The State of Alaska requires SWPPP’s for most projects, based on their areas of disturbance.
If your project disturbs 1 acre or more of land, you will need a full SWPPP that must meet the requirements of the State of Alaska Department of Environmental Conservation. In addition, you will need to submit a Notice of Intent a minimum of 7 days prior to beginning construction, and you will need to have regular inspections done by a Certified Erosion and Sediment Control Lead (CESCL) inspector.
If your project disturbs more than 10,000 square feet but less than an acre, you will need a similar SWPPP, but your project will not involve the DEC. The Municipality of Anchorage will need to review your SWPPP, and you will need regular inspections, but the inspector does not need to be CESCL-certified.
If your project is less than 10,000 square feet, you need a simplified Type I SWPPP. Typically, the contractor or owner can fill that paperwork out.
