For the purpose of assisting in the determination of whether an action may or will not have a significant effect on the environment, applicants for permits or other approvals shall file a written statement with the Town Planning Board, setting forth the name of the applicant; the location of the real property affected, if any; a description of the nature of the proposed action and the effect it may have on the environment. In addition, applicants may include a detailed statement of the reasons why, in their view, a proposed action may or will not have a significant effect on the environment. Where the action involves an application, the statement shall be filed simultaneously with the application for the action. The statement provided herein shall be upon an environmental assessment form prescribed by resolution of the Town Board and shall contain such additional relevant information as shall be required in the prescribed form. Such statement shall be accompanied by drawings, sketches and maps, if any, together with any other relevant explanatory material required by the Town lead agency.
