Building demolitions are a source of fugitive particulate matter emissions (including lead), which has strong evidence for public health concern. Building demolitions are also 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.
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.
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.
Each structure to be demolished has to be inspected for the presence of asbestos containing materials by a Missouri licensed asbestos inspector. The copy of the survey must be submitted to the Department with each Demolition Waste Application and Release Authorization form. Also, depending on the type or structure to be demolished supplemental information such as a NESHAP (40 CFR Part 61 Subpart M) form and commercial checklist may be required submittal. Application fee information is provided on the back of the Demolition Waste Application and Release Authorization form.
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. Notification of demolition activity day and time is a condition of demolition authorization. Notification instructions will be provided with all demolition authorizations together with a notification form. 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. 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).
