Cities of Dublin and Pleasanton | Disaster Debris Management Plan | 2022 <br />40 <br /> <br />a 50mm antistatic towel on a 25mm Mixed Cellulose Ester Filters (MCEF) cassette and <br />analyzed by transmission electron microscopy (TEM) NIOSH Method 7402 (high volume) <br /> Collect at least one upwind and two downwind dust samples from the immediate debris <br />removal area in a triangular configuration <br /> Personal air sampling collected in the breathing zone of site cleanup workers should be <br />conducted for dust, heavy metals, and asbestos. Sampling can be representative rather <br />than comprehensive so long as monitored personnel are representative of various on-site <br />operators, laborers, and supervisors <br /> The on-site air monitoring program shall include steps to modify debris removal operations <br />to reduce the potential for exposures above the NIOSH Recommended Exposure Limits. <br />The Threshold Limit Values are published by the American Conference of Governmental <br />Industrial Hygienists (ACGIH), or found in other protective occupational health guidance <br />used in the site-specific HASP <br /> Assign a full-time safety officer to the removal operations, preferably a CIH. <br /> At the conclusion of the debris removal project, a summary of air monitoring activities and <br />any resulting health and safety issues should be provided to the Project Manager or <br />Operations Chief <br /> <br />Off-site Air Monitoring <br />No off-site migration and/or emission of dust or airborne contaminants are required during debris <br />removal operations when appropriate dust mitigation controls are in place. However, a community- <br />based air monitoring program may be established to monitor off-site migration of airborne <br />contaminants, especially if adjacent neighborhoods are reoccupied. <br /> <br />Sampling or monitoring can also target sensitive population centers or locations such as schools <br />and hospitals. While community monitoring is not required during disaster recovery efforts, <br />increased community sensitivity following a disaster may justify a monitoring program. The following <br />activities support off-site air monitoring: <br /> <br /> Coordinate any monitoring and sampling efforts with the Alameda County Environmental <br />Health Departments and the BAAQMD. Additional state and federal resources are available <br />if local resources are unavailable or exhausted. The favored approach is an interagency <br />effort with either the BAAQMD or local health department as the lead agency. <br /> Develop a Sampling Plan and document community monitoring activities in a Community <br />HASP. <br /> Monitoring may be for particulate matter alone or in combination with asbestos or other <br />suspected contaminants. Particulate matter can serve as a proxy for the migration of other <br />particulate-type airborne contaminants, but not gases and aerosols, which need separate <br />monitoring. <br /> Direct read or near real-time dust measurement instrumentation such as a data ram is <br />preferred and allows immediate feedback to removal operations and to impacted <br />communities. <br /> If instituted, community monitoring should be conducted in both upwind and downwind <br />locations relative to debris removal operations and/or the immediate impacted area. <br /> Occupational health recommendations cannot be used in determining risk to public health. <br />Only public health guidance values can be used to interpret community monitoring data.
