Wind Turbine Considerations
If the land disturbed while erecting the turbine is greater than one acre, then a Stormwater Construction General Permit (ARR150000) is required.
Land disturbance between 1 acre and 4.99 acres is considered a small construction site and requires an Automatic Coverage Posting and development of a Stormwater Pollution Prevention Plan (SWPPP). Although submission of these documents to DEQ is not required, they should be kept on site. Small construction sites are still required to adhere to all requirements in the permit, although approval of the automatic coverage is not required and there is not an associated fee.
Large construction sites are any sites that are 5 acres or greater. Large construction sites are required to submit a Notice of Intent and SWPPP to DEQ and receive approval prior to beginning construction. Permits for large construction sites are typically issued two weeks from the postmark date.
More information, permits, and forms can be found in the Water Permits Section under Stormwater General Permits.
The following list of agencies is provided as a resource for individuals and facilities interested in erecting wind turbines. DEQ does not assume liability for this list or claim that it is all encompassing. It is meant to be used solely as an aid.
Federal Aviation Administration
If your facility maintains three or more turbines that are each over 200 feet above ground level, you will need to ensure they are marked and lighted properly. For more information, download Advisory Circular (AC 70/7460-1K) Obstruction Marking and Lighting

The Endangered and Threatened Species Evaluation may be used to get clearance for wind turbine construction, in most instances, from the U.S. Fish and Wildlife Service.
