7.1 Chapter Introduction Street waste disposal is an important consideration for municipal street sweeping programs because proper containment, treatment, and disposal is necessary to prevent pollutants from re-entering the environment. Disposal and storage facilities can become hotspots for potential pollution issues by concentrating contaminants that were previously distributed in the streets. Street waste disposal plans must consider state and local regulations, waste storage needs, and disposal fees. To most effectively manage and dispose of collected street waste, jurisdictions may elect to construct and operate a decant facility or create an agreement with another jurisdiction to use their facility. This chapter provides guidance on identifying street waste management and disposal methods, estimating waste quantities, and designing and operating decant facilities. The content of the sections in this chapter includes: • 7.2 Applicable Permit Requirements – Outlines applicable permit requirements and other regulations related to street waste disposal • 7.3 Street Sweeping Waste Treatment and Disposal – Describes methods for separation, storage, treatment, and disposal of solid and liquid street waste • 7.4 Decant Facility Sizing – Provides methods and considerations for estimating the size of a decant facility • 7.5 Estimating Street Waste Loads – Provides methods for estimating waste generated from street sweeping activities and variables that may impact street waste quantities • 7.6 Planning, Designing, and Operating Decant Facilities – Offers information related to constructing and operating decant facilities
