In addition to our CEMS installation services, Air Tox performs certification testing. This provides each client with a fully operational and certified CEMS system upon completion of the project. Air Tox also provides certification testing on CEM systems installed by other manufacturers in accordance with federal and state regulations.

Certifications are performed after the system has been installed and operated on-line for a shakedown period of 30 days. During this operational period, the calibration drift checks and percent of valid data capture will be checked and reported. After the process is completed and approved, Air Tox performs the Relative Accuracy, Calibration Error, and Response Time certification tests (as applicable) using US EPA reference methods. As part of the certification process, Air Tox provides the following:

• A Pre-Installation Protocol (PIP) discussing the system components, methodologies, and sampling location is prepared for review and approval by the applicable state environmental regulatory agency. This document is submitted prior to installation of the system. Modifications in the plan, if required, are made prior to the installation field effort.

• A protocol for submission to the respective state environmental regulatory agency outlining the Performance Specification Test (PST) procedures. Upon approval of the protocol, Air Tox schedules a mutually-acceptable test date with your facility. Air Tox performs the PST in accordance with 40 CFR Part 60, 75, BIF, or other applicable regulations, to determine the CEMS Relative Accuracy, Calibration Drift, Calibration Error, System Bias, and Cycle/Response Time (as applicable). In addition, for CEMS affected by 40 CFR Part 75, testing is performed to verify proper computation of emission rate, mass emissions, flow, and data substitution.

• A Quality Assurance (QA) manual is prepared by Air Tox according to US EPA requirements for CEM systems. The QA manual contains step-by-step procedures for the following tasks:

• Routine calibration of the CEM system
• Calibration Drift (CD) determination and adjustments
• Preventative maintenance of CEM system (including spare parts inventory)
• Data recording, calculations, and reporting
• Accuracy audit procedures to include sampling and analysis methods
• Programs of corrective action for malfunctioning CEM system.

The protocols and manuals meet or exceed all applicable state and federal regulations for content and format. Projects are always rigorously followed through to approval by regulatory agencies.

Additionally, Air Tox offers customized CEMS operational training as well as preparation and submittal of both hardcopy and electronic source Monitoring Plans. As part of CEM system quality assurance / quality control, Air Tox also prepares and submits facility quarterly emissions reports and XML Electronic Data Reports.
