~ . CASE # 7 REQUEST FOR SITE PLAN REVIEW; CASE OF VISION-EASE LENS By: Zoning Administrator Sylvia Frolik Background: Vision-Ease Lens is planning to utilize organic peroxide formulations in the manufacture of their polycarbonate based products. This material is considered a hazardous chemical. Proper storage and handling are addressed in materials published by several groups including the National Fire Protection Association (NFP A), Factory Mutual Engineering Corporation, and PPG Industries, the peroxide manufacturer. The peroxides are stored frozen until they are taken out of storage for immediate use. Vision-Ease plans to store very small quantities of this material on site: no more than 100 pounds of Class I peroxide and no more than 100 pounds of Class III peroxide. (Peroxides are classified by NFP A based on combustibility, Class I Being the most combustible and Class V being the least combustible). The material is not considered hazardous once it has been utilized in production. The empty storage containers require no special handling or disposal. The material poses no hazard to the environment if spilled. Observations: Factory Mutual incorporates the most restrictive guidelines for locating a detached storage building on a site relative to major buildings in the same site. Their normally recommended minimum separation is 100 feet along with a barrier. Vision-Ease is proposing a 250 square foot one-room metal building on a concrete slab on grade. It will be centered in a 46' x 46' area of crushed gravel, surrounded pya 6' chain link fence. There will be an earth berm approximately 9 feet high around the west, south and east sides of the building (the berm is higher than the building). The entrance to the building will be on the north side of the building. The building will be 100 feet from the nearest point of the proposed future expansion to the Vision-Ease facility and property lines. The building will house two typical residential style chest freezers which will hold polyethylene bottles or trays containing the peroxide. Each freezer will have a temperature sensor. The building interior will also have an ambient temperature sensor. Three digital temperature indicators will be located inside the storage building, and three will be located inside the main building, along with audible and visual temperatUre level signals at each location. In addition, temperatures will be monitored remotely by Vision- Ease's security/fire alarm system monitoring provider. The building will be electrically heated to maintain a minimum interior temperature of approximatelY 50 degrees Fahrenheit, and will have a thermostatically controlled exhaust fan to provide ventilation during the summer months. ,6
