Nt,,.,i2 ' TIGARD City of Tigard March 6, 2014 Code Unlimited Samir Mokashi 12655 SW Center Street Beaverton, Oregon 97005 Re: Alternate Materials & Methods -Agilyx Tigard Facility Flammable lc Liquid Protection Dear Mr. Mokashi, The City of Tigard accepts the Alternate Materials and Methods proposal dated 1/31/2014. The proposal was discussed with Mr. Ty Darby of Tualatin Valley Fire and Rescue. Given the existing conditions at the facility,we agreed that the approach taken with the proposal provides enough additional protection,in the single area that exceeds the AMQ, to allow the entire facility remain a Goup F-1 occupancy. Please note that any changes to the current configuration or amount of material will likely require a change of occupancy. For Record keeping, I will tie this AM&M to the building permit currently open at the facility. This is permit BUP2012-00233.

The site is located in the Wall Industrial Park at 7905 SW Hunziker Street, Tigard, Oregon. The 2 story building consists of an open ground level production area containing production equipment, raw material storage, employee areas, offices and building support areas. There is a small second floor with offices and a control platform overlooking the production equipment. The process involves heating plastic scrap material to produce a vapor. The low-pressure vapor is sent through welded steel piping to a condenser/coalescer on the production skid. The vapor is condensed to a Flammable IC Liquid on the production skid and stored in a welded steel tank. When the liquid quantity reaches 350 gallons, it is automatically pumped to an outdoor storage tank. The production system is a closed use system, continuously monitored by trained staff on the production floor and on the control platform at all times while the system is in operation. The closed use system that handles the vapor is provided with pressure sensors. When a pressure rise or drop is detected, an alarm is activated on the control panel, alerting the staff. The trained staff will assess the situation and initiate the draw-down of the tank and shut down the process if required. Spill containment is provided below the production skid, to contain the contents of the storage tank and the foam fire suppression system. A UV/IR flame detection system is provided at the skid, which will initiate an alarm on the control panel, alerting the staff. The flame detectors will provide an early warning, prior to smoke detection or sprinkler flow alarms. Once alerted, the trained staff will initiate a tank draw-down and use the portable foam fire suppression system.

The building meets all the requirements for a Group F-1 occupancy plus additional means of protection that are required for H-3 occupancy, and some which exceed H-3 requirements. Measures Required for F-1 Occupancy • The building is fully sprinklered. • Electrical installations on the production skid are classified as Class I Division 2. Measures Required for H-3 Occupancy • Ventilation will be provided at a rate of 1 cfm per square foot of floor area. • Pressure detection is provided for vapor within the processing system. • Emergency power is provided via uninterruptable power supply for alarm, engineering controls and fire detection/suppression systems. • An emergency generator is also provided for ventilation and critical processing functions. • The production skid has a spill containment trench underneath, sufficient to contain the contents of the storage tank and the portable foam suppression system. • Seismic bracing is provided for the production equipment and storage tank. Measures that Exceed H-3 Occupancy Requirements • The control platform will be staffed by trained employees at all times while the equipment is in production. • A UV/IR flame detection system will be installed on the production skid, which will alert the trained personnel, who will use the portable foam fire suppression system. • A 36-gallon portable foam fire suppression system is provided, operated by trained personnel. This is in addition to the building sprinklers. Code Unlimited LLC [2] www.codeul.com Mark VanDomelen 1/31/2014 Page 3 of 3 Reason for Alternate The process in the building involves the creation and storage of a Flammable IC liquid that exceeds the maximum allowable quantity(240 gallons)for a sprinklered building. Additional protection measures that are required for H-3 occupancy, and some that exceed H-3 requirements, are included in the building. The 240 gallon limit is for sprinklered buildings without cabinets. The 350 gallon quantity proposed is less than the 480 gallons permitted with cabinets, and the proposed measures provide a protection level beyond what would be provided by cabinets. With these measures in place, we believe the proposed design will provide equivalent protection to the code intent for closed use of 350 gallons of Flammable 1C Liquid.

(Ty.Darby @tvfr.com) Subject: RE:Agilyx Tigard facility Mark Below is a list of items required for H-3 occupancy that the Tigard facility does not meet. The only items that are nor met are: 1. Allowable area. (Not feasible to meet) 2. Occupancy separation from the rest of the building. (Not feasible to meet) 3. Low level exhaust pick up around storage areas. (Since containment and removal is provided in the design it meets the code intent for a low level exhaust pick up) 4. Break glass type ventilation shut off outside of room exits. (Not feasible to meet) If you need any additional information,please let us know.

(Ty.Darby0tvfr.com) Subject: RE: Agilyx Tigard facility Hi Tom, Sorry to"piece meal"this too much but can you please provide information on any requirements that would not be met for an H-3 occupancy? I know there would be occupancy separation requirements, allowable area concerns and possibly panic hardware requirements on the exits. Please list (and address if feasible)these and any other requirements that may be required if this were an H-3 occupancy. I have discussed this with Ty Darby from TVF&R and we are pretty close to signing off but we would like this information as part of the analysis.

We have the following responses to your questions/concerns: 1) The process requires a certain amount of holding time to allow proper separation of the oil and water to occur in the tank.This separation requires a specific volume of"hold-up"in the vessel,which is around 350 gallons. 2) The containment area will hold a capacity of 1,513.7 gallons.The size of the containment area is 30'-8"x 6'-1", or 187 square feet and 202.4 cubic feet. a. Tank amount before pump out=350 gallons. b. Foam system tank=36 gallons c. Sprinkler water amount at Ordinary Hazard 1 = 187 s.f. x.15 gpm x 20 minutes=561 gallons d. Total liquid requiring containment=947 gallons< 1,513.7 gallon capacity of the containment area. 3) The manual foam system provides additional and early fire protection in the unlikely event of a fire,which will be activated earlier than the sprinkler system. The robustness of the piping and Class 1,Div 2 electrical installations restricts the possibility of a fire by limiting leak and ignition sources. The portable foam system is located adjacent to the occupied control station.This control station is occupied at all times when the system is operating.The person manning the control station will be trained in the use of the foam system.When the UV/IR detectors activate the alarm on the control station,the person manning the station will move to the foam system and activate the foam spray onto the tank and skid.The UV/IR detectors provide early detection of a fire event.The location of the foam system adjacent to the control station ensures quick activation of the foam system. If you have any further questions or concerns,please give me a call.
