What materials do I need to submit to obtain a WES EPSC permit and a 1200-CN?
- Completed and signed WES EPSC permit application form.
- Submit a signed original of the WES EPSC application form and 1 pdf copy.
- The Erosion and Sediment Control Plan drawings. The drawings must follow the WES standard template drawings (especially the cover sheet) provided on the WES website.
- Submit 2 sets of the plan drawings for review.
- Upon preliminary plan approval submit 2 sets of the plan drawings and electronic pdf files of the complete set of plans. If the electronic pdf file is larger than 8 MB the drawings must be split into multiple files so no one file is larger than 8 MB file size.
- Submit the applicable WES fees. Fees cover the cost of plan review, permitting and inspections. The permit fee varies depending on the amount of disturbed area (see the fee descriptions listed below). Fees are payable directly to WES.
