Rider 7 Grant Program Air Quality Planning and Analysis Services

The Houston-Galveston Area Council (H-GAC) is seeking a qualified contractor to improve understanding of fine particulate matter (PM2.5) concentrations, composition, and contributing factors within the H-GAC Metropolitan Planning Area (MPA) through targeted monitoring, data analysis, and photochemical modeling. The project supports regional air quality planning by providing technically sound information to inform evaluation of emissions, transport influences, and potential control strategies. The contractor will be responsible for implementing a PM2.5 monitoring network, conducting data analysis, and developing a comprehensive modeling framework to evaluate PM2.5 formation, transport, and source contributions. The project will also include scenario and sensitivity evaluations to examine how changes in key inputs or conditions may influence PM2.5 patterns. • The project will focus on implementation of PM2.5 monitoring activities, analysis of newly collected monitoring data, advanced modeling and integrated technical assessment, and planning-oriented interpretation to support future air quality planning and coordination. • The contractor will be required to submit a draft and final Statement of Work (SOW), Quality Assurance Project Plan (QAPP), and supporting scope documentation. • The project will include at least five PM2.5 monitoring locations, with one location co-located at or near an existing regulatory monitoring site. • The contractor will be responsible for compiling, managing, and reviewing monitoring data, conducting comprehensive data validation and characterization, and comparing newly collected monitoring data with data from existing regional monitoring networks.
