Body
BACKGROUND
Since 1967, the City of Dallas has worked with the TCEQ and its predecessor agencies to support clean air monitoring and enforcement of air quality regulations through a set of renewing contracts for services. There are three contracts under which TCEQ funds the City’s Ambient Air Monitoring Group to monitor local air quality and purchase and maintain necessary equipment.
This action addresses Contract No. 582-23-40028 for monitoring PM 2.5 and Rockwall Ambient Air Monitoring. The City’s Air Specialists collect sample specimens from six PM samplers in Dallas County as well as the Continuous Air Monitoring Station (CAMS) in Rockwall County which monitors ozone and meteorological data. This program is of importance because of the serious health effects associated with exposure to fine particulates, also TCEQ requested that the City of Dallas operate the Rockwall (Rockwall County) continuous ambient air monitoring station as a part of the City's and Dallas/Fort Worth region's ambient air monitoring network. TCEQ purchased and installed major components of the station and will maintain these components at their expense, including all hardware and equipment required for the facility to be operational.
Authorization of this contract will allow the City to accept TCEQ funds and enable the City to continue the Rockwall/PM2.5 Ambient Air Monitoring Program. TCEQ reimburses the City of Dallas 100 percent of the cost associated to maintain the program.
