Attachment A iv.Surface Waters 1)Wetlands –Describe any anticipated physical effects or alterations to wetland features, such as draining, filling, permanent inundation, dredging, and vegetative removal. Discuss direct and indirect environmental effects from physical modification of wetlands, including the anticipated effects that any proposed wetland alterations may have to the host watershed. Identify measures to avoid (e.g., available alternatives that were considered), minimize, or mitigate environmental effects to wetlands. Discuss whether any required compensatory wetland mitigation for unavoidable wetland impacts will occur in the same minor or major watershed, and identify those probable locations. No wetland features or surface waters were identified within the project site; therefore, no impacts are anticipated. 2)Other surface waters –Describe any anticipated physical effects or alterations to surface water features(lakes, streams, ponds, intermittent channels, county/judicial ditches) such as draining, filling, permanent inundation, dredging, diking, stream diversion, impoundment, aquatic plant removal, and riparian alteration. Discuss direct and indirect environmental effectsfrom physical modification of water features. Identify measures to avoid, minimize, or mitigate environmental effects to surface water features, including in-water Best Management Practices that are proposed to avoid or minimize turbidity/sedimentation while physically altering the water features. Discuss how the project will change the number or type of watercraft on any water body, including current and projected watercraft usage. No impacts to surface water features are anticipated. 12.Contamination/Hazardous Materials/Wastes a.Pre-project Site Conditions – Describe existing contamination or potential environmental hazards on or in close proximity to the project site, such as soil or groundwater contamination, abandoned dumps, closed landfills, existing or abandoned storage tanks, and hazardous liquid or gas pipelines. Discuss any potential environmental effects from pre-project site conditions that would be caused or exacerbated by project construction and operation. Identify measures to avoid, minimize, or mitigate adverse effects from existing contamination or potential environmental hazards. Include development of a Contingency Plan or Response Action Plan. A Phase I ESA was completedin 2014 followed by a Limited Phase II ESA in 2015 to determine if any known contaminated properties or potential environmental hazards are located on or near the project site.The Limited Phase II ESA found the following: Two10,000-gallon diesel Underground Storage Tanks (USTs) Potential exterior site impacts related to historical automobile maintenance and repair, or other industrial processes conducted at the site Twin Lakes Station12 March 2020
