This information is also helpful to determine if available avoidance, minimization or compensatory mitigation measures will address the probable significant impacts or if an environmental impact statement will be prepared to further analyze the proposal. INSTRUCTIONS FOR APPLICANTS: [help] This environmental checklist asks you to describe some basic information about your proposal. Please answer each question accurately and carefully, to the best of your knowledge. You may need to consult with an agency specialist or private consultant for some questions. You may use “not applicable” or “does not apply” only when you can explain why it does not apply and not when the answer is unknown. You may also attach or incorporate by reference additional studies reports. Complete and accurate answers to these questions often avoid delays with the SEPA process as well as later in the decision-making process. The checklist questions apply to all parts of your proposal, even if you plan to do them over a period of time or on different parcels of land. Attach any additional information that will help describe your proposal or its environmental effects. The agency to which you submit this checklist may ask you to explain your answers or provide additional information reasonably related to determining if there may be significant adverse impact. INSTRUCTIONS FOR LEAD AGENCIES: Additional information may be necessary to evaluate the existing environment, all interrelated aspects of the proposal and an analysis of adverse impacts. The checklist is considered the first but not necessarily the only source of information needed to make an adequate threshold determination. Once a threshold determination is made, the lead agency is responsible for the completeness and accuracy of the checklist and other supporting documents. 2 H:\File Sys\WTR - Drinking Water Utility\WTR-13 - Studies & Project Development\WTR-13-0119 - Highlands 435 Zone Reservoir Replacement Prelim Design\SEPA CUP Master Site\envchlstHighlandsResRpl.doc USE OF CHECKLIST FOR NONPROJECT PROPOSALS: [help] For nonproject proposals (such as ordinances, regulations, plans and programs), complete the applicable parts of sections A and B even though questions may be answered “does not apply”. In addition the SUPPLEMENTAL SHEET FOR NONPROJECT ACTIONS (part D). Please completely answer all questions that apply and note that the words “project”, “applicant”, and “property or site” should be read as “proposal”, “proponent”, and “affected geographic area” respectively. The lead agency may exclude (for non-projects) questions in Part B - Environmental Elements –that do not contribute meaningfully to the analysis of the proposal.
