SEPA ENVIRONMENTAL CHECKLIST FOR Beverly Park Switching Station Expansion AGENCY P.U.D. NO. 1 of Snohomish County USE • Electric fields and magnetic fields (EMF) are associated with every power delivery system and electrical device. Possible effects upon human health from electric and magnetic fields continue to be investigated, with emphasis directed primarily at magnetic fields. The District looks to the research community for guidance and continues to monitor the research for definitive answers concerning EMF and human health but current research findings are inconclusive. There are no established or known levels of human exposure to power line magnetic fields which have been determined to be either safe or harmful. • The electrical equipment inside the switching station fence and the power lines outside the fence will generate electric and magnetic fields (EMF). EMF's are present during generation, transmission, distribution and use of electrical power. The fields are strongest adjacent to the source and rapidly decrease as the distance from the source increase. The placement of the electrical equipment inside the perimeter of the switching station fence and the arrangement of the rebuilt transmission line structures are designed to minimize the fields as compared to the arrangement of the existing facility. • The site includes an approximately 2,400 square foot area used for burial of concrete encased Transite pipe containing asbestos. The burial site was permitted and established by the previous owner and is covered with a four foot layer of concrete demolition material. This area is mapped but not currently fenced, nor signed, however the location on the site is not easily accessible to the public. 1) Describe special emergency services that might be required. • None beyond normal community emergency response. 2) Proposed measures to reduce or control environmental health hazards, if any: • The construction activities within the asbestos burial area will be restricted. The limits of the burial area will be fenced with a chain link fence and signed to limit access to the area prior to start of construction. b. Noise 1) What types of noise exist in the area which may affect your project (for example: traffic, equipment operation, other)? • Types of noise that exist in the area are traffic noise from Beverly Boulevard and Interstate 5. • There are no noises that will affect the project.
