Lummi Island Rock Quarry Expansion Huxley College of the Environment Western Washington University Environmental Impact Assessment Winter 2012 March 8, 2012 Dear Concerned Citizen: In compliance with the State Environmental Policy Act (SEPA), the following is Environmental Impact Assessment (EIA) for the proposed expansion of the Mineral Resource Lands (MRL) zoning overlay on Government Lot 3, Lummi Island, Washington. The proposed action calls for 27.5 acres of previously zoned Rural Forestry (RF) lands to be given a MRL overlay so that mining activities may be conducted in the future, most likely by the current parcel owners, Lummi Rock, LLC, and operators, Aggregates West. This EIA is an academic venture and was created by Huxley College students as a capstone course, Environmental Science 436, under the supervision of Leo Bodensteiner. Therefore there has been no endorsement made by the proposer, Lummi Rock, or Whatcom County and this should not be used as an official document. The document seeks to analyze the proposed action and two other reasonable alternatives for managing the site, (1) a “no action” alternative, and (2) moving the MRL overlay expansion to another gravel mine also operated by Aggregates West, the probable significant adverse and beneficial environmental impacts, and their relation to existing policies, rules, and regulations. Information included in this EIA was gathered from Whatcom County, the Lummi Island Conservancy, Washington Department of Fish and Wildlife, in addition to other sources collected through the collaborative work of Huxley students and faculty. To encourage citizen participation, an informational presentation will be held at 5:00 PM on March 7th, 2012 at Fairhaven Books located at 1200 11th Street, Bellingham, WA. The public meeting will include a PowerPoint presentation and will provide citizens with the opportunity to pose questions and concerns to be addressed with regards to the EIA. Hard copies of the document will be available at Wilson Library and the Huxley Map Library, which are located on Western Washington University’s campus. An electronic copy of the EIA will also be made available to the public through the Wilson Library digital collections. It will be able to be viewed at the following web address: http://content.wwu.edu/cdm4/browse.php?CISOROOT=%2Fhcc.

HUXLEY COLLEGE OF THE ENVIRONMENT WESTERN WASHINGTON UNIVERSITY Winter 2012 Fact Sheet Title: Mineral Resource Lands (MRL) Expansion, Lummi Island Quarry Description of Project: Amendment of the Whatcom County comprehensive plan to rezone approximately 27.5 acres of designated Rural Forestry to include a Mineral Resource Lands (MRL) overly on Lummi Island. Most of what remains of Government Lot 3, Lummi Island would be part of the expansion of the MRL, excluding the point off the east side of Smugglers Cove and a 200-foot setback along the shoreline.

The island is inhabited year round, but the number of residents doubles during the summer months. North Lummi Island supports the majority of its residents and is topographically flat. The southern half is mountainous and forested with limited amounts of development. There is a sandstone quarry located on the southeast side, directly abutting the shoreline. The quarry is owned by Lummi Rock LLC and operated by Aggregates West INC. Currently the quarry pit is 19 acres, but Lummi Rock has applied for a rezoning application to increase the mining area by 27.5 acres. A checklist was submitted under the State Environmental Policy Act (SEPA) to Whatcom County in December 2010, which was later revised and resubmitted in November 2011. The proposal would provide a Mineral Resource Land (MRL) zoning overlay on top of the current Rural Forestry (RF) zoning. This report was prepared in order to analyze and compare the potential environmental impacts of the proposed mine expansion, as well as two alternatives. The alternatives are expanding a limestone quarry located by Maple Falls, WA by the same 27.5 acres or take no action and prevent further expansion at either location. The potential environmental impacts were analyzed for the natural and built environment according to SEPA. The rocks originated as marine sediment layers that were tectonically shifted into a sloped position. Rock is extracted on the downslope side of the hill. The greatest environmental impact the mine creates is an increase in impervious surfaces. Bedrock is exposed after soils and vegetation are removed in order to access the rocks for extraction, and the ability of water absorption is lessened. Impervious services increase the amount of water runoff and sediment transportation out of the mining area. Due to the location of the mine, sediment is transported via water directly into Smugglers Cove leading to increased water turbidity and less light infiltration. Geologic stability is also lessened because of the mining activities when water does infiltrate between the rock layers or during seismic events. Expanding mining operations on Lummi Island
