What does the Permit Require? Stormwater Pollution Prevention Plan A practical erosion and sediment control plan says what and where erosion and sediment controls will be needed. Implementation The focus is putting practical and effective erosion and sediment controls on the ground and making sure they work. Sampling/Reporting Sampling water leaving sites larger than five acres is required. Sampling of sites less than five acres began October 2008. Sampling results help evaluate the performance of erosion and sediment controls on site. Sampling results can also trigger when more controls are needed. Inspections Weekly inspections by a Certified Erosion Sediment Control Lead are required. Sample reports must be submitted Ecology Fees Less than 5 acres $ 388 5-7 acres $ 631 7-10 acres $ 853 10-<20 acres $1,163 Greater than 20 acres $1,447 How do I get more Information?

Stormwater runoff has been identified as a significant source of pollution. Studies show that erosion from construction project sites put dirt and other pollutants into “Waters of the State”. A NPDES Construction Stormwater General Permit issued by the WA State Department of Ecology requires erosion and sediment controls are taken to prevent problems. These include: • Erosion controls like mulch and vegetation to keep dirt in place • Sediment controls like silt fences and sediment ponds that catch stormwater and construction runoff and let the dirt settle out “Waters of the State” include lakes, rivers, ponds, inland waters, underground waters, salt waters and other surface waters and watercourses within the jurisdiction of the state of Washington. This may include dry ditches, storm drains and road surfaces that have drains and ditches. Who Needs the Permit? If your project site is one acre or more of disturbed ground then you need a permit. If your project site is less than one acre, but is part of a subdivision or other common plan of development, then you need a permit. If there a potential for stormwater or construction waters to run off to “Waters of the State” that include the following, then you need a permit. • waterways on the site that may collect runoff • runoff off of site that goes to a ditch, wetland or creek • pond or ditch outlets • mud tracked off site onto roads, • some dewatering • catch basins How to Apply Erosivity Waiver An erosivity waiver is available for project sites under five acres during periods of low rainfall. Majority of projects within the Columbia Basin region may qualify. See the Ecology website for more information. http://www.ecy.wa.gov/programs/wq/sto rmwater/construction/ SEPA The project site must have a WA State Environmental Policy Act determination completed for sites 5 acres or more. There are no Categorical Exemptions. The SEPA process may take up to 45 days. Public Notice Two public notices are required to be published in a local paper, seven days apart. Application/Notice of Intent File a complete application with Ecology at their Headquarters in Lacey. This will begin a 38 day review. A coverage letter will be sent 31 days after the second public notice. http://www.ecy.wa.gov/programs/wq/sto rmwater/construction/
