The Department of Environmental Protection (DEP), Division of Air and Resource Management (DARM) is charged with regulation of Florida's air resource, including air quality monitoring, permitting and ensuring compliance of emission sources. The DARM regulates the state of Florida's air resource, implementing state, federal and U.S. Environmental Protection Agency requirements, and enabling the economic development of the state. Per Code of Federal Regulation (CFR), Part 58 - Ambient Air Quality Surveillance. Teledyne equipment meets the Federal completeness and quality assurance requirements (provided in 40 CFR Part 58) in support of the operational readiness of Florida's Statewide Air Monitoring Network. The single source request is to ensure inventory of back-up units and spare parts, and manufacturer repair of critical components, to maintain the operational readiness of the Statewide Air Monitoring Network. These PM monitors will ensure Federal requirements (40 CFR Part 58) for data quality and data completeness to enable the DARM to maintain trace level monitors for SO2, CO, and NO/NOy/NOx at NCore sites which are required in accordance with 40 CFR Part 58 and the State’s approved air monitoring network plan. Teledyne's PM monitors have a unique broadband LED detection system allows the DARM to continue the mission of the DEP.
