20.73.010 Purpose.
The primary purpose of this district is to implement the mineral resource lands designation of the Comprehensive Plan, established pursuant to RCW 36.70A.170, by allowing the type of activity that encourages and supports the opportunity for the extraction of minerals in areas of Whatcom County designated as containing resources viable for long-term commercial extraction. This district is also designed to discourage incompatible uses from locating upon mineral resource lands where the extraction of minerals occurs or can be anticipated. (Ord. 2005-079 § 1, 2005; Ord. 97-069, 1997; Ord. 92-029, 1992).
20.73.020 Application.
.021 The Mineral Resource Lands Special District is an overlay zone which covers only those areas designated as Mineral Resource Lands pursuant to the Washington State Growth Management Act. Any regulations contained herein which are more restrictive than those in the underlying zone districts or in the Shoreline Management Program shall apply. (Ord. 97-069, 1997; Ord. 92-029, 1992).
20.73.050 Permitted uses.

.053 Gravel bar scalping projects within the jurisdiction of the Shoreline Management Program. (Ord. 97-069, 1997; Ord. 92-079, 1992; Ord. 92-029, 1992).
20.73.100 Accessory uses.
.101 All accessory uses in the underlying zone districts are permitted as accessory uses. (Ord. 97-069, 1997; Ord. 92-029, 1992).
20.73.130 Administrative approval uses.
The following uses are permitted subject to administrative approval pursuant to WCC 22.05.028:
.132 Rock crushing within Commercial and Rural Forestry Districts when located further than 2,000 feet from a rural or residential district. (Ord. 2015-016 Exh. A, 2015; Ord. 2003-061 § 2; Ord. 97-069, 1997).
20.73.150 Conditional uses.
.151 All conditional uses in the underlying zone districts shall remain conditional uses unless expressly prohibited by this chapter.
.152 Mineral processing facilities including rock crushing, asphalt and concrete batch plants and accessory washing and sorting.
.153 Surface mining subject to Washington State’s Surface Mining Act (Chapter 78.44 RCW); provided, that:
(1) The notification requirements of WCC 22.05.070(4)(b)(ii) shall be expanded to all property owners within 2,000 feet of the external boundaries of the subject property.
(2) At minimum, the activity adheres to the development and performance standards of WCC 20.73.650 and 20.73.700. In addition, no excavation shall occur within the five-year zone of contribution for designated wellhead protection areas. Excavations may occur within the 10-year zone of contribution outside of the five-year zone of contribution if they are not within 10 vertical feet of the seasonal high water table. If a fixed radii method is used to delineate a wellhead protection area, the surface mining applicant may elect to more precisely delineate the wellhead protection boundary using an analytical model; provided, that the delineated boundary proposed by the surface mining applicant is prepared by a professional hydrogeologist; and further provided, that the delineated boundary has been reviewed and approved by the Washington State Department of Health. The hydrogeologist shall be selected by mutual agreement of the county, water purveyor, and applicant; provided, if agreement cannot be reached the applicant shall select a consultant from a list of no less than three qualified consultants supplied by the county and water purveyor.
(3) Buffers are established of sufficient size and with sufficient vegetation or berming to ensure that noise, dust, noxious weeds and other impacts to surrounding property owners are within applicable regulations and performance standards. When completing a reclamation segment, buffers may be reduced for a three-month period to establish the final reclaimed topography.
(4) The applicant provides insurance policies or a similar type of protection as appropriate to cover potential liabilities associated with the proposed activity; renewals of bonds or insurance shall be submitted upon expiration of previous bonds or insurance. The bonding agent shall notify the county on any change of status in the bond.
(5) Application of additional site specific conditions may be required to mitigate potential impacts that are not otherwise regulated through WCC 20.73.650 and 20.73.700 or through federal, state, or local regulations.
(6) Notice of the decision shall be mailed to all property owners within 2,000 feet of the external boundaries of the subject property within two days of issuance of the decision. The applicant shall provide typed, self-adhering mailing labels with the names and addresses of all property owners within 2,000 feet of the subject property with the application to facilitate the notice.
(7) Where the underlying zoning is Rural Forestry or Commercial Forestry, any mineral extraction permit shall include the condition that no greater than 40 acres can be mined within the permitted area at any one time. Additional acreage may only be added after an equal amount of previously mined land has met reclamation criteria as identified on an approved Department of Natural Resources surface mining reclamation permit, less the area of any roads constructed in previously mined land, to access a newly permitted area.
(8) When mineral extraction is proposed on a parcel that was not designated Mineral Resource Lands prior to January 1, 2015, all existing mines on parcels contiguous to and held by more than one percent common beneficial ownership or beneficial interest with the proposed mine shall be in complete compliance with all operating permits and regulations before extraction of the proposed mine may commence.
(9) When mineral extraction is proposed within 500 feet of a gas or petroleum transmission pipeline, a site specific geotechnical analysis of potential impacts to the pipeline is required. The analysis shall show that mining will not result in an increased likelihood of the pipeline becoming exposed or rupturing during an earthquake, and shall consider various seismic scenarios with a two percent probability of exceedance in 50 years on both proximal crustal faults and at the Cascadia Subduction Zone. (Ord. 2021-040 Exh. A; Ord. 2015-016 Exh. A, 2015; Ord. 97-069, 1997; Ord. 92-079, 1992; Ord. 92-029, 1992).
