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