A Demolition Waste Application and Release Authorization form must be submitted to the St. Louis County Department of Public Health (DPH) Environmental Services for all demolition projects occurring in St. Louis County. The Demolition Waste Application and Release Authorization form is reviewed by both the DPH Air Pollution Control Program and Waste Management Program. Depending on the type or structure to be demolished supplemental information such as asbestos inspections, asbestos notifications, and commercial checklists may be required with each Demolition Waste Application and Release Authorization form submittal. Application fee information is provided on the back of the Demolition Waste Application and Release Authorization form.
Notification of demolition activity day and time is a condition of demolition authorization. Notification instructions will be provided with all demolition authorizations. A notification form is provided. Inspections will occur at any residential or commercial demolition activity to ensure that appropriate measures are taken to prevent dust from becoming airborne and extending beyond property boundaries. Airborne dust or dustfall created by demolition activity has negative impact on public health and property.
Building demolitions are a source of fugitive particulate matter emissions (including lead) which has strong evidence for public health concern. Building demolitions are a source of fugitive particulate matter emissions which damages physical property. Particulate matter emissions caused by lack of control at building demolition projects is preventable. The St. Louis County Department of Public Health Air Pollution Control Program performs inspections of building demolition projects to determine their compliance with applicable local, State, and Federal Air Pollution Control Regulations. An inspection fee is applicable to certain residential demolition projects and demolitions which are subject to the Asbestos NESHAP (40 CFR Part 61 Supbart M).
Recent studies, including one in the City of St. Louis, have identified demolitions as a potential source of environmental lead exposure to nearby residents. Simple dust suppression methods are likely to reduce the contamination considerably. Lead dust and other harmful particulates which settles outdoors can enter the residential environment on the soles of shoes, clothing, or open windows/doors.
There is a health equity component to dustfall containing lead and other harmful particulates from demolition activity. Many of the homes being demolished are in older, urban areas. These older homes are more likely to contain high amounts lead.
