No development can occur in the floodplain until permit is issued.
Fill out and sign the permit application form (both pages).
Permit fee is $500; make check payable to Canadian County Floodplain Management.
Include with permit:
§ Detailed set of plans and specifications, including flood-proofing measures designed by a licensed engineer.
§ Copies of other required permits including those from the Corporation Commission (permit to drill) and 404 permit from US Army Corps of Engineers (if needed.)
§ Copy of Spill Prevention and Counter Measure Plan.
§ Emergency Evacuation Plan in case of imminent flood event.
All structures and pieces of equipment in the 1% chance/100-year floodplain must be flood-proofed (designed in a manner to reduce or eliminate flood damage, e.g. anchoring) or elevated.
If the elevation method is to be used, a base flood elevation (BFE) must be established and elevation of structures and/or equipment must be 2 feet above the BFE.
Flood-proofing measures must include the following: 1. Tank batteries and other equipment installed at the site in the floodplain shall be tied down to prevent flotation and lateral movement. 2. Protection around any vulnerable equipment such as the well head or xmas tree must be installed to keep flood debris from damaging equipment which could release product into floodwaters or send equipment floating downstream.
Pipelines must be buried at least 48 inches; 72 inches under rivers and creeks. A statement acknowledging this is required.
A closed pit system is required.
Any material stored on the site that is highly volatile, flammable, explosive, toxic or water reactive should be protected to at least the level of the 500-year flood.
Drill site pad and road to well do not need to be elevated.
After drilling is completed and site is built, flood-proofing certificates for all flood-proofed equipment and structures, signed by a licensed engineer, must be submitted. Submit elevation certificate if anything was elevated above the BFE. The floodplain administrator will inspect the site again at this time.
The developer shall provide a list of equipment installed at site after completion. This office must be notified if equipment is added after completion. If site is sold or assigned this office must be notified.
