(3) Appropriate warning signage (e.g., electrical hazards) shall be placed on wind turbine towers, electrical equipment, and SWES/WES.
(4) Any SWES/WES found to be unsafe by the building official shall be repaired by the landowner and/or project owner to meet federal, state and local safety standards, according to the regulatory authority of the building official and applicable provisions per WCC Title 15.
.072 Blade Tip Height.
(1) The blade tip of any SWES with a cumulative rated output up to and including 50 kW shall, at its lowest point, have ground clearance of no less than 20 feet, as measured at the lowest point of the arc of the blades.
(2) WES with a cumulative rated output greater than 50 kW shall, at its lowest point, have ground clearance of no less than 30 feet, as measured at the lowest point of the arc of the blades.
.073 Over-Speed Controls.
All SWES/WES shall be equipped with over-speed controls to limit rotation of blades to speed below the designed limits of the system. No changes or alterations from the certified design shall be permitted unless accompanied by a licensed professional engineer’s statement of certification.
.074 Flicker Analysis for WES.
A flicker analysis is required for all WES. The analysis shall include the duration and location of flicker potential for all buildings and for roadways within a one-mile radius of each turbine within a project. The applicant shall provide a site map identifying the locations of shadow flicker that may be caused by the project and the expected durations of the flicker at these locations from sunrise to sunset over the course of a year. The analysis shall account for topography but not for obstacles such as accessory structures and trees. Flicker at any building shall not exceed 30 hours per year within the analysis area. Flicker in excess of the limits established in this chapter shall be grounds for the county or his/her designee to order operational adjustments, which may include mitigation measures requiring cessation of operation during periods when flicker affects any building, for all noncompliant WES.
.075 Wildlife Protection for WES.
Prior to permit approval provide documentation from a qualified professional wildlife biologist (Chapter 16.16 WCC, Article 8, Definitions) verifying the following:
(1) Endangered or Threatened Species. Development and operation of a WES shall not have a significant adverse impact on endangered or threatened fish, wildlife, plant species, their critical habitats, or other significant habitats identified in the Whatcom County Comprehensive Plan and/or other current studies or plans relevant to the region and recognized by the county.
(2) Other Species. The project development and/or operation plan shall be sited, designed, operated and monitored to prevent WES from having a significant adverse impact on migratory birds, raptors and bats. (Ord. 2012-041 § 1 (Exh. A), 2012; Ord. 2008-043 § 1, 2008).
.081 Sound Modeling.
As part of the conditional use permit process, all WES proponents shall provide a report by a qualified independent acoustical consultant approved by Whatcom County PDS and in accordance with standard industry best practices, that models the sound transmission of the proposed WES at the project property lines and indicates that the WES, when operated properly, will conform to the sound performance requirements of this chapter. (Ord. 2012-041 § 1 (Exh. A), 2012).
If two or more complaints from different households are received within two weeks of each other, and documented at a particular site, a sound measurement will be conducted within 10 business days by a qualified consultant approved by Whatcom County.
The cost of the sound measurement shall be the responsibility of the WES owner/operator. The operator shall reimburse the county for the expense within 10 days of billing.
Measurements shall be conducted where the complaints were documented.
If an evaluation shows that the WES is operating outside of its permitted sound performance standards, the operator will have 30 days to adjust the system(s) or terminate operations.
To avoid frivolous complaints, any household(s) that registers a complaint against a WES that is proven to be in compliance shall be responsible for the costs of any future complaints originating from the same household(s) for two years unless the WES project has expanded and/or proven to be in violation of the sound performance standards. At the discretion of Whatcom County PDS, if it appears residents are abusing the complaint process, complaints may be compiled for three months at a time and then a sound study conducted at all of the locations. No WES project shall be required to conduct more than two sound measurements at any one adjacent property per year unless the WES project has expanded and/or proven to be in violation of the sound performance standards.
Complaints originating from properties located farther than one mile from a WES project do not trigger the complaint process. (Ord. 2012-041 § 1 (Exh. A), 2012).
.101 Abandonment.
Absent notice of a proposed date of decommissioning, WES project shall be considered abandoned when the project fails to operate for more than one year without the written approval of the director or designee. The director or designee shall determine in its decision what proportion of the project is inoperable for the project to be considered abandoned and shall notify the property owner. Within 120 days of receipt of notice of abandonment or within 120 days of providing notice of termination of operations to the county, the owner of a wind energy system must comply with the removal requirements in WCC 20.14.102. If the property owner/project owner fails to remove the WES in accordance with the requirements of this section within 120 days of notice of abandonment, the county shall have the authority to enter the property and physically remove the WES. Financial surety funds shall be used to pay for removal and restoration.
.102 Removal Requirements.
When a SWES (with a total height that exceeds the height of the underlying zone) or a WES is scheduled to be decommissioned, the project owner/property owner shall notify the county by certified mail of the proposed date of discontinued operations and plans for removal. Within 120 days of receipt of notice of abandonment or within 120 days of providing notice of termination of operations, the owner of a wind energy system must:
(1) Remove all wind turbines, above-ground improvements, and outdoor storage. Property owners of WES in the HII Zone, and SWES in the AG and CF Zones, may choose to leave foundations in place and intact, partially or in whole, for approved, permitted reuse, except that in the AG Zone foundations left in place must be located such that the distance between SWES foundations and foundations of existing buildings shall not exceed 50 feet.
(2) Remove all hazardous material from the property and dispose of the hazardous material in accordance with federal, state and local law.
(3) In addition to removing the wind turbine generator, the owner shall restore the site by planting native or other approved vegetation to minimize erosion.
.103 Insurance.
Proof of continuous liability insurance shall be submitted to Whatcom County indicating coverage for potential damages or injury to landowners, occupants, or other third parties. For WES with a rated output greater than 50 kW the required insurance is $2,000,000 aggregate and $1,000,000 per occurrence. Whatcom County shall be named on the liability policy as additional insured. The insurance carrier shall be instructed to notify all applicable governmental authorities of any delinquency in payment of premiums. The liability policy shall be endorsed to notify the county of any cancellation 30 days in advance. Failure to provide such insurances shall be considered abandonment and full and sufficient grounds for termination of the permit and disposal of the equipment and appurtenances as stated herein.
.104 Financial Surety.
As a condition of WES permit approval, the applicant shall be required to provide a form of surety (i.e., post a bond, or establish an escrow account or other means) at the amount of 150 percent of the estimated full cost of project decommissioning less the approved, documented salvage value of any applicable project materials and equipment, naming Whatcom County as the beneficiary, with 50 percent due prior to final project approval, 25 percent due within 12 months of the date of final project approval, and 25 percent due within 24 months of the date of final project approval, to cover costs of WES removal in the event the county must remove the facility. Nothing may prevent the county from seeking reimbursement from the WES project owner. The project owner is responsible to the county for any costs related to decommissioning that exceed the amount of financial surety.
As part of the decommissioning plan, the applicant shall submit a fully inclusive estimate of the costs associated with removal, accounting for reasonable salvage value of any applicable project materials and equipment, prepared by a qualified professional. The decommissioning plan shall provide that the decommissioning funds shall be reevaluated every five years from the date of substantial completion of the WES to ensure sufficient funds for decommissioning and, upon mutual agreement by the applicant and the county at that time, the amount of decommissioning funds shall be adjusted accordingly.
Prior to permit issuance, the applicant shall provide the county with a copy of the financial surety device or another approved mechanism.
.105 Decommissioning Plan.
As part of the permit approval process, a decommissioning plan shall outline the anticipated means and cost of removing WES at the end of their serviceable life or upon becoming a discontinued use. The cost estimates shall be made by a competent party, such as a professional engineer, a licensed contractor capable of decommissioning or a person, firm, partnership, corporation or other entity with suitable expertise or experience with decommissioning, as determined by the building official or designee. The plan shall also identify financial surety to pay for the decommissioning and removal of the WES and accessory facilities. The plan shall also address road maintenance during and after the decommissioning. (Ord. 2012-041 § 1 (Exh. A), 2012).
(1) SWES/WES shall comply with all current adopted Whatcom County codes and ordinances, including but not limited to WCC Titles 15, 16 and 23.
(2) SWES/WES must comply with regulations of the Federal Aviation Administration (FAA), along with requirements within WCC 20.80.675, Height limitations surrounding airports.
(a) If necessary, an applicant may be required to submit the following information for analysis of airspace obstructions in relation to WCC 20.80.675: mean sea level (MSL) of adjacent airports; MSL of proposed site; Euclidean distance from adjacent airports to proposed site; total elevation/height of SWES/WES structure.
(3) All SWES/WES electrical systems shall comply with requirements per the Washington State Department of Labor and Industries and the current adopted edition of the National Electrical Code (NEC) when and where applicable.
(4) All SWES/WES with the intention to tie to their respective utility provider’s grid system shall meet the requirements of Chapter 80.60 RCW, Net Metering of Electricity. (Ord. 2012-041 § 1 (Exh. A), 2012; Ord. 2008-043 § 1, 2008. Formerly 20.14.080).
