Ranch Quarry – SEPA Environmental Impact Statement (EIS)
Water Resources / Wells / Wetlands / Stormwater / Traffic / Asbestos/Rural Character
Whatcom County – CUP 2023-00001
To: Whatcom County Planning & Development Services
Community members respectfully submit the following scoping comments for the Environmental Impact Statement (EIS) for the proposed Ranch Quarry project. These comments address groundwater, aquifers, domestic and community wells, wetlands, stormwater, transportation impacts from large gravel trucks, naturally occurring asbestos risk, and the resulting impacts to rural lifestyle, public health, safety, and community character.
A. Groundwater and Aquifer Impacts
- Which mapped and unmapped aquifers underlie and are down gradient of the project site, and what are their classifications?
- What is the seasonal high groundwater table beneath the excavation footprint, including extreme precipitation events?
- What minimum vertical separation will exist between the quarry floor and groundwater during all phases?
- Is there hydraulic connectivity between shallow groundwater, deeper aquifers, and nearby wells?
- The EIS must include a complete hydro-geologic conceptual model identifying recharge areas, flow directions, vertical gradients, and site-specific groundwater vulnerability, using conservative assumptions where data is incomplete.
B. Domestic and Community Wells
- How many private, shared, and community wells exist within ½ mile, 1 mile, 1.5 miles, and down gradient flow paths, including wells serving the Columbia Valley Urban Growth Area approximately 1.5 miles east of the project site?
- Which wells are most vulnerable to drawdown or contamination?
- What baseline water quality testing will be conducted prior to quarry operations?
- What guarantees exist for well repair, replacement, or permanent alternate water supply provision?
- The EIS must include a ‘No Net Harm to Wells’ standard with enforceable financial assurance.
C. Groundwater Contamination and Asbestos Risk
- How will blasting fractures alter subsurface flow paths?
- What is the potential for mobilization of naturally occurring contaminants, including asbestos-form minerals?
- Where will fuels and chemicals be stored relative to recharge areas?
- How will stormwater infiltration systems prevent groundwater contamination?
- The EIS must evaluate worst-case asbestos disturbance, airborne transport, and exposure scenarios.
D. Surface Water and Groundwater Interaction
- What evidence confirms or refutes hydraulic connectivity to Saar Creek?
- Which wetlands contribute to groundwater recharge and how will they be impacted?
E. Storm Events and Climate Change
- The EIS must evaluate stormwater systems using 50- to 100-year storm assumptions, including climate-driven increases in storm intensity.
- What is the contamination risk if stormwater systems fail during extreme events?
F. Monitoring and Enforcement
- How many groundwater monitoring wells will be installed and where?
- What contaminant thresholds trigger shutdown or corrective action?
- What adaptive management actions are available if impacts occur?
- How are uncertainties disclosed and addressed conservatively?
G. Cumulative and Long-Term Impacts
- How will cumulative groundwater impacts be analyzed over 50–100 years?
- Who is responsible for post-closure groundwater risks in perpetuity?
H. Transportation, Traffic, and Road Safety Impacts
- Trip Generation and Haul Volumes: How many total truck trips per day (inbound/outbound) will occur during each project phase? What is the maximum daily haul volume during peak production? What are the expected hours of operation for hauling, including early morning and evening periods?
- Route Analysis: What are the proposed haul routes, including all intersections, bridges, curves, grades, and narrow rural segments? What alternatives exist to reduce impacts to residential areas and rural roads?
- Road Capacity and Level of Service: Can existing rural roads safely accommodate industrial-scale truck volumes? What changes in congestion, delay, and safety risk will occur at key intersections?
- Road Design Compatibility: Are travel lanes, shoulders, and sight distances sufficient for large gravel trucks? What is the risk of conflicts between heavy trucks and school buses, cyclists, farm equipment, pedestrians, and local residents?
- Accident Risk and Safety Impacts: What is the projected increase in collision risk due to heavy truck traffic? How will turning movements, braking distance, and limited sight lines affect safety on rural roads?
- Emergency Response and Evacuation: How will heavy truck traffic affect emergency response times? What happens during roadway blockages, winter conditions, or major storm events?
- Road Damage and Maintenance: What is the expected increase in pavement deterioration and road maintenance costs? Who pays for long-term road damage, and what enforceable agreements guarantee repairs?
- Traffic Enforcement and Compliance: How will speeding, engine braking, load securement, and truck routing be enforced? What monitoring and penalty structure will exist for violations?
- Seasonal and Weather Impacts: How will winter conditions, flooding, or storm damage affect safe truck operations?
- Financial Responsibility: The applicant must be designated as fully responsible for all roadway damage, repair, upgrade, and long-term maintenance costs attributable to project traffic.
I. Rural Lifestyle, Community Character, and Quality of Life
- How does a high-intensity industrial quarry operation align with existing rural land use patterns?
- What are the noise and vibration impacts from blasting and truck traffic?
- What light pollution impacts will occur?
- What are the air quality impacts from dust, diesel exhaust, and airborne asbestos fibers?
- What are the public health risks to vulnerable populations?
- How will residents’ enjoyment of property and outdoor use be affected?
- What are the impacts to property values and long-term community stability?
J. Cumulative Impacts to the Rural Community
The EIS must evaluate cumulative impacts to transportation systems, rural lifestyle, public health, environmental resources, and naturally occurring asbestos disturbance, airborne transport, and long-term exposure risk over the full project timeline.
Additional Scoping Requirements Requested by Community Members
- Reasonable worst-case scenario analysis for stormwater and operational failures.
- Irreversibility of groundwater impacts and long-term risk disclosure.
- Independent baseline testing and transparency.
- Financial assurance and bonding for long-term water, health, and infrastructure impacts.
- Conservative treatment of uncertainty where data is incomplete.
- Transportation mitigation enforceability.
- Naturally occurring asbestos identification, air monitoring, dust control, and contingency shutdown thresholds.
- Rule out presence of naturally occurring asbestos through core drilling using best practices and best available science.
Conclusion
Community members respectfully request that Whatcom County require a thorough and conservative EIS scope that fully evaluates groundwater impacts, aquifer vulnerability, domestic and community wells, wetlands, Saar Creek connectivity, stormwater failure risk, long-term cumulative impacts, heavy truck traffic impacts, rural lifestyle impacts, and asbestos risk.
