See here a public bid where a particularly low-cost standalone CEMS unit (will still need a good deal of engineering and construction above this cost) for a single basic chemical species (SO2) costs $15,000. In an area like Deer Park, TX, you might need 8-35 of these per monitoring station (highest variety of chemicals will be near 3rd party tank farms like ITC, along major chemical pipeline networks, at chemical railyard terminals, and ocean shipping terminals). Engineering costs to get a building put in place, telecommunications, power delivery, and SCADA control integration would be expected to run at least another $100,000 not counting any in-house project management hours. They'll need regular expensive maintenance and some installed redundancy. To give you a sense of the scale, here are just energy pipelines (natural gas, crude oil, etc). These maps lack thousands of chemical pipelines. https://www.prnewswire.com/news-releases/energy-web-atlas-world-pipeline-solution-enables-faster-decisions-300871054.html https://www.prnewswire.com/news-releases/energy-web-atlas-wo... https://pvnpms.phmsa.dot.gov/PublicViewer/ https://pvnpms.phmsa.dot.gov/PublicViewer/ Here are some maps of very basic commodity chemical pipelines, but cost $2,000 each to purchase. https://www.petrochemwire.com/maps-and-data/ https://www.petrochemwire.com/maps-and-data/ This one facility here is about 380 ft x 350 ft. There is a single pipeline going to this tiny facility which carries around 7 million pounds of chlorine per day. But that pipeline is just serving a tiny 3 acres of the western hemisphere's largest industrial complex in Freeport, TX which spans well over 13,000 acres. Just extracting the chlorine from salt water for this complex requires enough electricity to power 400,000 homes. https://www.google.com/maps/place/Freeport,+TX+77541/@28.9612012,-95.3235122,146m/data=!3m1!1e3!4m6!3m5!1s0x8640595961a3e7ad:0x42e685217bd37cba!8m2!3d28.9541368!4d-95.3596617!16zL20vMF95bjk?entry=ttu https://www.google.com/maps/place/Freeport,+TX+77541/@28.961...
