Continuous Emissions Monitoring System (CEMS) and Air Monitoring Directive (AMD) audits are a routine part of regulatory compliance, yet many facilities still find themselves rushing to gather documentation or clarify procedures as the audit date approaches. With regulations constantly increasing expectations around data integrity, quality assurance, and operational transparency, preparation has become a year-round responsibility rather than a once per year task. What are Internal Independent Inspections/Audits? CEMS Annual Inspections/Audits: The 2021 Alberta CEMS Code and Environment Canada EPS 1/PG7 require an annual evaluation of the CEMS system and quality assurance plan (QAP). Audits review the entire year’s CEMS data including performance tests (Relative Accuracy Test Audits (RATA) and Cylinder Gas Audits (CGA), reported data, maintenance and corrective maintenance records, staff training requirements, and QAP accuracy. AMD Annual Inspection/Audits: The 2016 Alberta Air Monitoring Directive (AMD) requires facilities to complete an annual audit once every three years to ensure the AMD and Quality system in place is adhered to. Audits evaluate the air monitoring equipment, including passive and ambient stations, operations, and reporting activities against the quality system and AMD. What Are Common Issues Preparing for a CEMS and AMD Audit? Most facilities don’t struggle because they lack data but because the data is scattered across systems, teams, and formats. Common issues we see at audit time include: Missing or inconsistent calibration records Gaps in preventative and corrective maintenance logs Outdated Quality Assurance Plans (QAPs) Staff uncertainty about procedures or regulatory expectations Performance tests with incorrect methodology or documentation Unclear documentation of previous audit findings and corrective actions Inaccurate or inconsistent data summaries Many of these challenges trace back to deeper root causes. On the technical side, data is often scattered across multiple platforms, accessed by different users, or stored using inconsistent naming conventions and filing structures making it difficult to retrieve quickly. Operational factors also play a role, including staff turnover that can lead to gaps in system knowledge, training may not keep pace with regulatory changes or turnover, and maintenance programs may be more reactive than proactive. A Four-Phase Framework for CEMS and AMD Audit Preparation Alliance Technical Group supports facilities across Canada in navigating these requirements with confidence. Our auditing team brings deep technical expertise and practical experience with CEMS operations, source testing, ambient monitoring, and regulatory reporting, giving organizations the insight and confidence to effectively prepare for these evaluations. By the end of each audit, the goal is for the facility to feel confident in the performance of their CEMS and ambient systems, be aware of any regulatory risk that needs to be addressed and understand where opportunities for improvement exist. Audits can help identify areas for improvement, allowing organizations to implement solutions before issues lead to costly failures. Below is a simplified version of the approach Alliance Technical Group uses with clients. Phase 1: Gathering CEMS Documentation and Calibration Records The facility is requested to gather all documentation related to: Approvals Quality Assurance Plans (QAPs) Daily reports and calibration records Performance testing reports (CGAs, RATAs, manual stack surveys) Preventative and corrective maintenance logs Recertification data (if applicable) Previous audit findings and evidence of remedial actions Air data and reports (AMD forms, EDR forms, ambient data, monthly, quarterly, and annual reports, contraventions, submission confirmations) These documents are the foundation of the audit. Phase 2: On-Site Evaluation of CEMS and Ambient Monitoring Systems Audit evaluations examine a wide range of system components, including overall system performance, data acquisition processes, staff readiness, and gap assessments such as missing documentation, incomplete logs, or outdated procedures. During this phase of the audit, the auditor typically spends time on-site interviewing technicians, field inspection of the monitoring system, reviewing the quality assurance plan and standard operating procedures, reviewing documentation and records, and consulting with regulatory specialists. Phase 3: Audit Review, Close-Out Meetings, and Reports This portion of the audit process includes a sit down with all pertinent personnel to discuss findings, areas for improvement, and have discussions with the facility on improvement options. Following close out, reports are completed and submitted to the facility to include findings in their monthly, quarterly, or annual reporting. Phase 4: Implementation of Findings This phase is one of the most critical steps following the audit. It relies heavily on the facility to review the identified opportunities for improvement and findings, then implement any adjustments, updates, or enhancements to their system as appropriate. All actions taken should be thoroughly documented and retained for the following year’s audit. Our auditing team is always happy to provide guidance with any questions that pop up during this phase. What Makes Alliance Technical Group's Audit Approach Different Tailored preparation based on your facility’s systems and regulatory obligations Cross functional expertise spanning CEMS, ambient monitoring, emissions testing, DAS configuration, and regulatory reporting our auditing team has unique experience in a diverse range of air regulations and in-field work. Proactive identification of issues and opportunities for improvement before they turn into bigger concerns, or costly mistakes. Clear, actionable recommendations rather than generic checklists Support during and after the audit, including corrective action planning and guidance. Critical Success Factors for a Compliant CEMS or AMD Audit From our experience, successful audits share these characteristics: Documentation is complete, organized, and accessible Staff are trained and knowledgeable in their roles Maintenance logs are detailed and up to date QAPs reflect current operations Data is validated regularly--not just before the audit Preparing for a CEMS or AMD audit doesn’t have to be stressful. With the right structure, documentation, and team readiness, facilities can move through the audit process with confidence and clarity. The key is shifting from reactive to a proactive, year-round approach-one that strengthens data integrity, reduces compliance risk, and supports operational excellence. As the regulatory landscape continues to evolve, audit readiness becomes not just a requirement, but a strategic advantage. By following the steps outlined in this guide, your facility can ensure smoother audits, reduced regulatory risk, stronger performance, and long-term compliance success.

Overview of ECCC Chromium Electroplating, Anodizing and Reverse Etching Regulations Environment and Climate Change Canada (ECCC) released the Chromium Electroplating, Anodizing and Reverse Etching Regulations in 2009 to limit hexavalent chromium emissions from facilities that use chromic acid in electroplating, anodizing and reverse etching operations.  The regulations were amended in 2020 to improve consistency and clarity in the regulations and remove outdated references. Compliance Options for Controlling Hexavalent Chromium Emissions The regulations require any facility that uses 50 kg or more of chromium trioxide per calendar year for electroplating, anodizing or reverse etching to limit the release of hexavalent chromium compounds using one of the following control technologies: Install and maintain a control device to limit hexavalent chromium before its released into the environment (point source option),  Limit surface tension on the tanks, or Use tank covers. What Are the Release Testing Requirements? Facilities that elect to install and maintain a control device, typically a scrubber, must perform a release test every 5 years to demonstrate that the hexavalent chromium emissions are less than the limit of 0.03 mg/Rm 3 .   Who Needs to Test in 2026? Any facility that is operating on the original 5-year testing schedule , meaning they haven’t failed a release test, replaced their control device, modified their tanks or made changes to the ventilation system, will most likely need to test in the 2026 calendar year. How to Prepare for ECCC Release Testing Contact Alliance to get a quote and schedule testing Submit a signed Release Test Notice to ECCC at least 30 days prior to testing Record the rectifier amperage for the 30 days of use preceding the Release Test Conduct the Release Test with the rectifier amperage set to the average amperage for the previous 30 days of use Submit the Release Test Report to ECCC within 75 days of the final test
