LTE provides ambient and indoor air quality services for environmental remediation, transportation, and oil and gas projects nationwide. LTE’s air quality experience includes regulatory compliance, being a regulatory liaison for our clients, pre-permitting strategic planning, negotiating agreements with agencies in response to air quality enforcement actions, preparing compliance evaluations, performing air dispersion modeling, and conducting hydrocarbon gas leak detections using our optical gas imaging camera.
We have assessed regulatory applicability of ambient air regulations including Prevention of Significant Deterioration (PSD), New Source Performance Standards (NSPS), New Source Review (NSR), reasonably available control technology (RACT), best available control technology (BACT), and other standards for the oil and gas industry (refineries, compressor stations, and gas processing facilities). LTE’s extensive permitting experience includes preparing Air Pollutant Emission Notices (APENs), Non-Criteria Reportable APENs, construction and operating permits including Title V and PSD permits. LTE has prepared emission inventories and SARA Toxic Release Inventory (TRI) reports, and has developed Quality Assurance/Quality Control plans for continuous emissions monitoring. We are experienced in recording and utilizing meteorological data required for the preparation of permits and compliance reports.
LTE has performed ambient air quality compliance sampling and reporting for contaminants including volatile organic compounds (VOCs), semi-volatile organic compound (SVOCs), chlorinated solvents, particulates, metals, formaldehyde, petroleum hydrocarbons, methane gas, radon gas, pesticides/herbicides, and polychlorinated biphenyls (PCBs).
LTE’s indoor air quality experience addresses non-compliance and human health risks associated with contaminants of concern migrating into residential, commercial, and industrial facilities, and with contaminants associated with work related processes or emanating from materials and/or equipment. Our indoor air investigations have included performing assessments beneath and within buildings to determine the source of indoor air pollution; designing, installing, and monitoring of soil vapor points to evaluate contaminant migration pathways, type, and quantity; collecting indoor and ambient air samples, surface samples, samples of various materials, mold, and animal feces; and evaluating the most economically feasible technology for addressing indoor air pollution.
LTE has designed and installed mitigation and monitoring systems for projects that have ranged in size from a residential home to large systems beneath and within multi-story commercial and industrial buildings.
