MENTAL�.0 E . :>>FOR PROJEC LEVELS The State Environmental Policy Act(SEPA),Chapter 43.21 C,RCW,requires all governmental agencies to consider the environmental impacts of a proposal before making decisions. Although the State Environmental Policy Act does specify certain categorical exemptions,these can,in some cases, be modified by local agencies if there is a likelihood of probable significant adverse impacts from an otherwise categorically exempt project. Although the SEPA rules do not generally require environmental documentation when a project is categorically exempt,many smaller projects are, in,fact,a part of a larger whole which is not exempt. Also,under recent guidelines issued by the Washington State Department of Ecology,,it is recommended that agencies reviewing projects show that SEPA was considered.. This would be consistent with a 1980 State Court of Appeals decision which held that agencies should consider likely environmental effects before applying the SEPA categorical exemptions. The City of Renton has developed this abbreviated checklist to assist in doing this. Please answer each question and attach your answers on additional pages if you need more space. Do not leave any question blank--if a question does not apply,please note this after the question: • • Please remember to attach a vicinity map., project narrative, site plan.•and.one complete set of project plans.

Could the proposed project alter or obstruct views in the immediate vicinity? X No Yes. If yes, please describe. 12. Would the proposed project displace any existing recreation uses on site? X No Yes. If yes, please describe. 13. Will the project result in an increased need for public services (for example, fire or police protection, schools, etc.)?. No Yes. If yes, please explain. CERTIFICATION The above answers are true and complete to the best of my knowledge. I understand that the City of Renton is relying on them.in order to consider the likely environmental effects of the above described project. I have attached a vicinity map,proect narrative,site plan and one complete set of project plans. k Signature: �`�� .

Piping is to be installed from the tank farm to the manufacturing building with distribution to several locations within the manufacturing building. The scope of work is to include tank and pump foundations, mechanical equipment and piping, and electrical power and controls installation. The new coolant tank, T-10, pumps and piping system are to provide a separate and independent coolant storage and delivery system from the existing antifreeze system. The new system is to very closely duplicate the existing system. The system will initially be used to store and forward premixed coolant. The piping will distribute premixed coolant to several locations within the factory. At a future date the fill system at the main assembly line will be modified to mix the coolant with water at this point of use. At this time the tank will be used to store coolant concentrate. The concentrate will be pumped to the factory at which point a dedicated pipe will convey the concentrate to the future mixing system at the main assembly line. A second mixing system will be added near the west wall of the factory. This mixing system will supply mixed coolant to the mixed coolant distribution system. The new tank will be built to UL 142 standards. Tank venting will be by the same manufacturer as currently installed for the other tanks in the tank farm. 1 11/4/98 2.0 'THEORY OF OPERATION 'Delivery tank trucks will connect to the new tank truck unload/tank fill pipe. ,An emergency shut off valve and strainer will be located at this connection. ;Two positive displacement pumps, one operating and one spare, will continuously operate to pressurize the delivery system. The system pressure will be regulated by a pressure control valve on the recirculation line from the discharge of the pumps back to the tank. The delivery system piping will be routed across the pipe bridge to the ,manufacturing building. All portions of the piping outside, not over the ;spill containment area, will be double contained FRP piping. Piping within the building will not require double containment. 3.0 ,SECONDARY CONTAINMENT CAPACITY There are two containment areas. The north area has a net containment ,volume of 13,576 gallons and the south containment area has a net containment volume of 5,273 gallons; for a combined total of 18,849 gallons. The two containment areas are connected by a flume. The curb height of both containment areas is level. The containment area will be required to contain the water from a 24 hour rain from a 25 year storm equivalent to 3.4 inches. This will require a storage capacity of 6,422 gallons based on the gross area of the tank farm containment areas. The total required containment volume is: Antifreeze coolant tank volume - 7,500 gallons Rainfall volume - 6,422 gallons Total required containment volume 13,922 gallons • The available containment volume is: Containment volume - 18,849 gallons 2 11/4/98 4.0 TANK LEVEL AND SYSTEM CONTROLS Over filling of the tank will be prevented by the control system. An ultrasonic tank level sensor , identical to the sensors installed on the other tanks in the tank farm, will be installed and tied into the existing alarm and control functions. During tank filling, an alarm will sound when the tank level reaches 85% of the tank capacity. If the tank level reaches 90% of the tank capacity the fill valve will close and stop the filling operation. Emergency system stop buttons, one located at the tank farm and several located at key work stations in the factory, may be used to stop the dispensing operations at any time a problem is identified to prevent an antifreeze spill. 3 11/4/98 • �I T LAKE WASHINGTON • SEATTLE ! • _ goo PROJECT ti SITE p a S: RENTON Z m �� as N 8TH ST ..� Y z �J 405 p N6W- <o p ST w 4 „ I Pi• 0N 4TH Q • 900 • —OAT WY z � WY ; f o (z) Of> C F` • FIGURE A-1 ��►•-411I VICINITY PLAN L� SCALE: N.T.S. 0 ( — 0'' _ N.
