Source Testing: Protect Your Business with Accurate Compliance, Reporting
Our source testing measures emissions at the source, such as stacks, vents, and exhaust points. We use EPA-approved methods and state-of-the-art equipment to perform on-site sampling and analyze pollutants released into the atmosphere. The emissions we track include particulates, volatile organic compounds (VOCs), hazardous air pollutants (HAPs), and greenhouse gases. Working with us for source testing benefits your company in many ways, including:
- Regulatory Compliance: The EPA, state agencies, and local air districts mandate source testing to verify compliance with Clean Air Act requirements, Title V permits, NSPS, NESHAP, and SIPs. Companies that fail to perform these required tests can face violations, fines, and shutdown orders.
- Permit Verification: Many air permits require periodic stack testing to verify that your emissions are within allowable limits. Source testing provides the documentation you need for renewals and audits. If you don't have valid test results, your facility could lose operating permits or experience delayed permit renewal.
- Accurate Emissions Data: Relying on outdated or estimated data can lead to under- or over-reporting, which places your compliance at risk. On-site testing produces accurate and site-specific data and gives operators a clear picture of their emissions profile.
- Method-Specific Testing: Improper testing methods can lead to invalid results, which invite enforcement actions or failed inspections. We utilize approved protocols specific to the pollutants and equipment being tested.
- Emission Factor Development: Using inaccurate emission data can artificially inflate your reported emissions and raise regulatory scrutiny. Source testing generates custom emission factors that reflect your actual conditions.
- Support for Reporting & Modeling: Inadequate data compromises the accuracy of modeling reports and exposes your company to liability. Source test data is required for emissions inventories, dispersion modeling, and health risk assessments.
- Operational Optimization: Undetected equipment issues elevate emissions, create energy waste, and lead to compliance violations. Testing solves this by identifying inefficiencies and malfunctions in your pollution control equipment.
- Enforcement Response: Contesting violations or negotiating favorable outcomes is difficult without credible test documentation. Accurate source testing data supports your case in the event of an EPA Section 114 request or a violation notice.
