Cities of Dublin and Pleasanton | Disaster Debris Management Plan | 2022 <br />39 <br /> <br />pressure to generate a high mist fog stream. The fire nozzle should have an adjustable flow <br />rate, preferably 20 to 60 gallons per minute, and constructed of hard-coated aluminum with <br />brass and stainless-steel internal components. Plastic nozzles should not be used. While <br />the costs of metal firefighting nozzles are significantly more than plastic nozzles, metal <br />nozzles are only able to generate a sufficient fog to control dust. <br /> All burn ash and debris must be sufficiently wetted 48 to 72 hours in advance of initiating <br />removal of the material. The water shall be applied in a manner so not to generate significant <br />runoff. Engineering controls for stormwater discharges must be in place prior to dust control <br />operations. <br /> All waste material that is not loaded out at the end of each workday should be stockpiled, <br />sufficiently wetted, and/or covered to prevent the off-site migration of contaminants. <br /> All waste haulers who observe loading operations outside of the vehicle cab, and/or covering <br />(e.g., tarping) the trailer or container must wear Level C PPE. <br /> All approved landfill operators that may come in contact with the waste during off-loading <br />operations should follow their facilities protocols for wearing PPE and respiratory protection. <br /> All ACM and debris removed from the property, site or area must be manifested and <br />transported for disposal to a permitted treatment, storage, and disposal facility in good <br />standing with local, state, and federal agencies. <br /> Cal/OSHA may require procedures for the receiving landfill facility to establish an appropriate <br />site safety plan for the protection of the facility employees to potential ACM in the waste <br />stream. <br /> Disposal facility emergency waivers, and suspension of regulations for disposing of wastes <br />generated from a disaster or large-scale event, must be coordinated with the Local <br />Enforcement Agency (LEA) and the Regional Water Quality Control Board. <br /> <br />Air Monitoring and Sampling <br />Air monitoring and sampling activities should be conducted in the exclusion zone (on-site) and <br />along the perimeter of sites during debris removal activities, as well as during non-work hours to <br />establish relevant background air pollution levels. Air quality management practices and <br />engineering controls used during emergency debris removal should be in compliance with the Bay <br />Area Air Quality Management District (BAAQMD) guidance which can be found at <br />https://www.baaqmd.gov/. <br /> <br />On-site Air Monitoring <br />An on-site (industrial hygiene) air monitoring program must be in place at the immediate debris <br />removal area to protect respiratory health. The following are required dust abatement and <br />mitigation practices: <br /> <br /> Document on-site air monitoring activities in a site-specific Health and Safety Plan (HASP) <br /> All personnel entering the immediate removal area should be required to wear Level C <br />PPE, as defined in CCR Title 8 Section 5192; this level of PPE may be downgraded based <br />on results of industrial hygiene air sampling <br /> Sample/monitor for dust, heavy metals, and asbestos. Particulate matter monitoring shall <br />be done by direct reading instruments for real-time analysis. Heavy metal sampling can be <br />conducted via cartridge or filter analysis using National Institute for Occupational Safety <br />and Health (NIOSH) Method 7300 (metal scan). Asbestos samples should be collected with
