Resolution Copper Mining LLC (RCML) is overseeing a meteorological and air quality monitoring program to support several efforts during the mine development phases: environmental assessments, impact analyses, and documents required by the National Environmental Policy Act (NEPA); meteorological and air quality data to be processed and used as input for AERMOD (American Meteorological Society/Environmental Protection Agency Regulatory Model) dispersion modeling; and air quality baseline data and AERMOD analyses in support of RCML’s application to the Pinal County Air Quality Control District (PCAQCD) for air permit(s).

This monitoring plan includes details of installation, operation, maintenance, and/or regulatory requirements of multiple monitoring stations in areas of potential emission sources for RCML facilities.
