Certified Erosion Sediment Control Lead training

King County Department of Natural Resources (DNRP) is presenting its annual Certified Erosion Sediment Control Lead (CESCL) training required by the Washington State Department of Ecology (Ecology). DNRP will offer a one-day refresher class and a two-day initial training course, both of which provide certification for a period of three years. Once you have taken the two-day class, a one-day refresher is required every three years. Please sign up for a class by sending an email to Gary-Paul Reinke.

Upon completing this class, you will be automatically registered with Ecology. If you are not sure about your current training status, please refer to Ecology's CESCL database (external link). King County will not be able to provide this service for you as we don’t have the resources to track status for the 70-100 students we train.

One-day CESCL recertification class (April)
The one-day refresher class will be held April 7 at the King Street Center building in the 8th Floor conference room. This course is a refresher course for those who have CESCL certification that expired in 2015 and needs to be renewed. No paper manuals will be issued, instead a CD with the training documentation will be provided. All materials will also be available online. If needed, certified students can use the materials in their private offices. In addition, this materials can be used by staff for their individual needs. This class is NOT the class for you, if you have NOT been certified or your certification has expired. Staff with expired certification are required to retake the two-day class.

Two-day certification class (May)
The two day training course will be held on two successive days in May (May 5-6). The training will take place in two locations. The first training day will be at the King Street Center (201 South Jackson, Seattle), 8th floor, starting at 7:30 AM. This training will include presentations from four certified instructors. Training materials will be provided. Coffee, snacks, water will be available in the classroom. Lunch is on your own, however, there are many restaurants within a 5-minute walk of King Street Center.

The second day of this course will be conducted at the King County Roads Renton Shops, located at 155 Monroe Ave NE, in Renton. The meeting will be held in the J-Building crew meeting room. There is plenty of parking at the north end of the complex. If you park anywhere else, you will be asked to move your vehicle. Depending on which side you drive in from, you will see the huge parking area in front of the D-Building. Park there and walk around D-Building to the J-Building. Coffee, snacks, and water will be available in the classroom. Lunch is on your own, and there are many restaurants within a 5-minute drive.

Most of the coursework will involve hands on field work and each student must supply their own Personal Protection Equipment (PPE). This equipment is mandatory for this coursework which consists of installing a variety of BMPs for ditches and side slopes at the Renton site. Required field gear includes:

  1. Waterproof boots (steel toes not required)
  2. Hard hat
  3. Raingear
  4. Clothing appropriate for the weather (you may want to bring an extra set for the ride home – expect to get muddy and wet)

There will not be extra equipment, and without it you cannot participate.

The two-courses will cover the following subjects:

  • Introduction and Erosion Impacts
  • Erosion Processes and Influencing Factors
  • Stormwater Regulations
  • The Storm Water Pollution Prevention Plan (SWPPP)
  • Construction Site Monitoring
  • Best Management Practices (BMP’s)
  • Practical applications

Coffee, snacks and water will be provided during the days we are in the 8th floor conference room at the King Street Center. Lunch is on your own for all class days, however, there are many places to walk to downtown and a very short drive from the Renton shops for a variety of food choices.
