The Thermal Desorption Automated Gas Chromatograph with Flame Ionization Detection (TD/AutoGC/FID) monitors for 56 target volatile organic compounds (VOCs) in ambient air. Equipment must have United States Environmental Protection Agency (EPA) federal reference or equivalent method designation for Photochemical Assessment Monitoring Stations (PAMS) required to perform ozone precursor analysis. MINIMUM GENERAL SPECIFICATIONS 1. The ozone precursor monitoring system must meet the following compatibility requirements. A. The system must be capable of operating with existing Texas Commission on Environmental Quality (TCEQ) data systems: i. Leading Environmental Analysis and Display System (LEADS), and ii. AutoGC Oracle database including the necessary interface personality module (IPM) to control the autoGC and valving provided in the most current compatible communications software. B. The system must be capable of connecting existing software systems allowing site operators to remotely adjust method settings and to remotely control the autoGC system via the most current compatible communications software. C. American Standard Code for Information Interchange (ASCII) output must be compatible with TCEQ’s LEADS and autoGC Oracle systems. D. Software must interface with the existing chromatography data system (including the most current compatible communications software and the autoGC instrument program) to generate the necessary sequences and specific methods to schedule quality control (QC) checks. QC checks include daily calibrations and blanks and any other checks required by the TCEQ PAMS quality assurance project plan (QAPP) (available upon request). E. Software must allow automatic ingestion of data files into the TCEQ LEADS database. F. Software must create data files in the .txo format compatible with the current communications software. Data files must be able to be imported to the “build sequence” module of stated software. G. Each data file must include a file naming paradigm that designates the name of the site, column, date, and hour of the sample collected.
