NSPS OOOOa: Updates, Equivalency, and the Alternative Work Practice
On October 15, 2018, EPA proposed technical revisions to the NSPS OOOOa. The proposal addressed many topics, including the application process for the use of emerging technologies for fugitive emissions detection. There have been various efforts to develop frameworks for understanding equivalency but several questions remain unanswered, particularly around how EPA will evaluate potential alternatives. On December 22, 2008, EPA published a voluntary alternative work practice for LDAR using optical gas imaging, which may provide some insight into future equivalency evaluations for sources in NSPS OOOOa. Since promulgation of the alternative work practice, advancements have been made in leak detection technologies that warrant examination of revisions to that rule as well. This presentation will provide a brief status update of the technical amendments to NSPS OOOOa including examining key questions regarding emerging technologies and equivalence to the OGI fugitive emissions program. This presentation will also explore how updates for the alternative work practice may provide insight for evaluating equivalency for OOOOa. 1 Hour Presentation.
Lightweight, Modular OOOOa Certified OGI Camera Core for Handheld, UAV, or Fixed Mount CMS
The Ventus (OGI) camera core features a 640 x 512, 15-micron pixel-pitch, "Hot" midwave-infrared (MWIR) detector array providing unmatched thermal sensitivity and weighs only 580 grams (1.28 lbs.), with lens. Designed to optimize the detection and visualization of hydrocarbon gas leaks, such as methane, propane, butane, and 20 others. The “Hot-MWIR” Ventus OGI is a lightweight, low-power, camera core that can be integrated into gimbals/enclosures for manned or unmanned aerial system platforms or for fixed mounted continuous monitoring systems. Sierra-Olympic’s compact (146.6 mm x 70.9 mm x 73.1 mm/5.77 in x 2.70 in. x 2.88 in.) OGI camera features a special narrow bandpass cold filter in a miniature, long-life, closed-cycle Stirling cooler with an f/1.5 cold shield and an optimized, light weight, f/1.5, 25mm lens. State-of-the-art components including the detector, cooler, and lens design, combine with a selection of digital and analog inputs/outputs (Camera Link, H.264 IP Video, NTSC/PAL video plus RS-232/RS-422 serial camera control) to make this camera core an ideal optical gas imaging solution for integrators, OEMs and end users. Additional features include: a 32GB SD storage card, Contrast Limited Adaptive Histogram Equalization (CLAHE), Local Area Processing (LAP), Automatic Gain Control (AGC), Sharpening, DeNoise, Gas Enhancement Mode (GEM) and Electronic Image Stabilization (EIS). Optional items will include Target Tracking, Telemetry, NMEA and GPS i/o.
