Page 7 Health and Safety Plan and Soil Management Plan Gleason Park Apartments Property April 21,2010 SOIL MANAGEMENT PLAN (SMP) GENERAL Environmental investigations have revealed elevated concentrations of lead sporadically in site soils. The primary source of the lead in site soils is believed to be weathering of lead-based paints from residential structures that occupied the site for over 100 years. Human health risk assessment has shown that the residual lead in site soils does not pose an unacceptable risk to site workers and occupants, considering a multi-family residential use scenario. However, it is considered prudent to implement some basic soil management procedures during any future work that engages/disturbs site soils. Further, special measures would be necessary if site soils or other subsurface materials are planned to be removed from the property. SITE CONTROL MEASURES Site control measures should be implemented during any work at the subject property that engages/disturbs site soils. Site control measures to be implemented at the site during future maintenance work are as follows: • Any workers whose activities may engage soils at the subject site should be notified of the residual lead conditions and the site control measures described herein. Workers should read and understand this document. It is the responsibility of the property owners or managers to provide this document to workers, and to provide assistance in understanding the information presented in this document (such as translation for non-English speaking individuals). • Dust control measures should be implemented to limit or prevent airborne soil particles during activities that involve soil disturbance. An effective dust control measure is the wetting of exposed soils to limit airborne soil particles. Wetting can be accomplished via liberal sprinkling of exposed soils with a garden hose or other suitable means. Additionally, areas of exposed loose soil could be covered if necessary to prevent wind disturbance. The actual methods used for dust control will depend on the nature of the soil disturbance activity, the size of the area disturbed, soil moisture content, and weather conditions. As a general rule, measures should be implemented so that no visible dust is generated during site activities. • Based on low-level hazard associated with the lead in site soils, extensive construction equipment decontamination procedures are not warranted. However, any significant amount of site soil adhering to tools or construction equipment (such as earthmoving equipment, backhoes, etc.) should be removed from the equipment and left on site prior to demobilizing. No soil should be removed from the property unless the procedures described below are implemented.
