Household Hazardous Waste Collection Facility – Lexington, Kentucky
Magna Engineers is providing design, bidding, and construction administration services for HVAC, plumbing, fire protection, and electrical disciplines for this project. The project includes the renovation of an existing City-owned building which was originally designed to serve as wash bays for City-owned vehicles.
The new facility is designed to allow residents to drop off items that are regulated as solid waste, but when collected, must be stored, transported, manifested, and disposed of properly. Such materials may include oil based paint, acetone, batteries, propane storage tanks, antifreeze, etc. The building design includes the required spaces for collection, handling, bulking, and storage of these materials. The materials are then collected by third-companies which can properly dispose of the materials. In the past, the City has provided for scheduled collection of such materials with hazardous material disposal companies, with limited windows of collection. The completion of this project will allow regular opportunities for residents to dispose of household hazardous waste materials.
It was imperative that the design of the facility be closely coordinated with the City’s procedures for the types and quantities of materials which will be collected and stored, in order to meet the stringent building code requirements which apply to such facilities. The building is designed with 100% dry type fire suppression. Containment is required to accommodate spillage of the stored liquid materials, as well as the fire suppression flow. Leak detection is required which provides alarm in the event of detected liquids in the containment system. Appropriate ventilation measures are provided, in accordance with code requirements for this facility, including a standby power system as required for backup of ventilation systems. The building is classified as a Class I, Division 2 hazardous area, and all materials and wiring methods are specified accordingly. The facility is designed in strict accordance with the International Building Code, International Fire Code, and NFPA 30 for Flammable and Combustible Liquids.
