The Department of Ecology (Ecology) reviewed the environmental checklist and has the following comment(s): SOLID WASTE MANAGEMENT: Derek Rockett (360) 995-3176 All grading and filling of land must utilize only clean fill. All other materials may be considered solid waste and permit approval may be required from your local jurisdictional health department prior to filling. All removed debris resulting from this project must be disposed of at an approved site. Contact the local jurisdictional health department or Department of Ecology for proper management of these materials.
TOXICS CLEANUP: Dean Malte (360) 999-9584
No confirmed or suspected contaminated sites are located on or within 750 feet of the project area. If any contamination is encountered during work in the project area, please report it to Ecology (per WAC 173-340-300) via the online ERTS at https://ecology.wa.gov/Footer/Report-an-environmental-issue/statewide-issue-reporting-form. WATER QUALITY/General Permit Unit: Jacob Neuharth (360) 706-4599 Erosion control measures must be in place prior to any clearing, grading, or construction. These control measures must be effective to prevent stormwater runoff from carrying soil and other pollutants into surface water or storm drains that lead to waters of the state. Discharges must not cause or contribute to a violation of surface water quality standards, groundwater quality standards, sediment management standards, and human health-based criteria. Sand, silt, clay particles, and soil will damage aquatic habitat and are considered to be pollutants.

If there are known soil/ground water contaminants present on site, additional information will be required to be submitted. For contaminated construction sites, contact Evan Wood at evan.wood@ecy.wa.gov, or by phone at (360) 706-4599. Construction Stormwater General Permit: The following construction activities require coverage under the Construction Stormwater General Permit: 1. Clearing, grading and/or excavation that results in the disturbance of one or more acres and discharges stormwater to surface waters of the State; and 2. Clearing, grading and/or excavation on sites smaller than one acre that are part of a larger common plan of development or sale, if the common plan of development or sale will ultimately disturb one acre or more and discharge stormwater to surface waters of the State. a) This includes forest practices (including, but not limited to, class IV conversions) that are part of a construction activity that will result in the disturbance of one or more acres, and discharge to surface waters of the State; and 3. Any size construction activity discharging stormwater to waters of the State that a) Determines to be a significant contributor of pollutants to waters of the State of Washington. b) Reasonably expects to cause a violation of any water quality standard. Applicants may apply online or obtain an application from Ecology's website at: https://ecology.wa.gov/Regulations-Permits/Permits-certifications/Stormwater-general-permits/Construction-stormwater-permit. Some projects may be eligible for coverage under an Erosivity Waiver. Construction site operators must apply for a permit at least 60 days prior to discharging stormwater from construction activities and must submit it on or before the date of the first public notice. Ecology’s comments are based upon information provided by the lead agency. As such, they may not constitute an exhaustive list of the various authorizations that must be obtained or legal requirements that must be fulfilled in order to carry out the proposed action. If you have any questions or would like to respond to these comments, please contact the appropriate reviewing staff listed above.
