COLONEL DAVID HALSEY P.E. 4-30-2012 One of the most studied mysteries of atmospheric science is how a gas molecule such as carbon dioxide (CO₂), which is almost one and a half times heavier than the air column, can defy gravity and rise to the upper atmosphere. It’s understandable how a heavier gas can be propelled within the boundaries of the Hydrologic Cycle (aka Water Cycle) because of the mixing (thermal, wind ...more »
Improving Air Quality
How does a manufacturing compliance officer decide if they need to follow New Source Review (NSR) or New Source Performance Standards (NSPS) regulations if they have repaired or replaced a "facility" that resulted in an increase in emissions as defined by EPA? This is important since the requirements for NSR and NSPS are not the same. For example, a NSR review is required if the capital costs of the work exceeds 20% ...more »
The EPA seems reluctant to assess compliance with ozone standards in Metropolitan Statistical Areas on an annual basis. I live in an area that has exceeded the ozone standard for 4 years and yet we are officially still in attainment. The EPA should review ozone attainment annually to protect citizens from unhealthy air.
The Am Lung says EPA is going to publish a map of wood smoke pollution problem areas. Good. Put put a range on the total pm estimated so gov will know the pm likely. It is not NAAQS but tells where threats are believed to be occurring and threats to life and health have to be stopped and investigated per essential services policy of the DHHS. Then burning by stoves can be prohibited in problem areas. Pellet stoves will ...more »
There is no chance we can reduce global point source pollution (like cars) enough to matter at this point. (Will we invade China or Brazil to force them to drive alternate days or to stop burning rain forest?) We should continue changing the dynamic of technology, sure. But we must push a "New Era", possibly with a "Moonshot" political impetus, regarding big picture mitigation: In America we clean nearly every drop ...more »
Many people that have become dependant upon fires to make their living, have been discovered to have been starting fires whenever a cut to their budget is approuched. We need to address this matter by creating job shifting measures to help protect against such costly illegal behavior. Plus, I think stricter regulations need to be made to prevent the extreme alteration of diesel pick up exhaust systems, within our communities. ...more »
Federal suggestions for pollution control and car emissions testing in a local area facility. Federal reward for compliance and caring.
I'm a high school student and not sure how to get this idea implemented. I'd like to start a contest in DFW to see which county can reduce their ozone readings for a 90-day period starting in July. The county with the greatest percentage drop in readings (compared to a 3-year average for each county) would win. They would be "The Biggest Ozone Loser." If citizens would just try to help one day a week, we could make a ...more »
Creation of innovative technology through science & engineering to develop machines capable of atmospheric pollution capture and chemical conversion of pollutants into non-hazardous states, safer or reusable forms.
PCV (positive crankcase ventilation), the first smog device mandated to be installed in cars beginning in 1964. PCV captures blowby gases escaping into the crankcases below the pistons and redirects the toxic blowby gases back into the intake manifold through a series of large rubber hoses and a pulsing valve. New PCV hoses are airtight and works well until several years later when the rubber hoses tend to lose it pliabilty ...more »
Often, I get nearly knocked out from inhaling sewage gases oozing through manholes in big cities. They are so bad . I just thought about installing big fans to suck air through the manholes to keep the sewage gases moving in the right directions that is toward the treatment plants where they belong! This can also help suck in heavy traffic smog to help reduce air pollution on the busy streets. The fans can be solar powered ...more »
Its time that we engineer diesel electric semi trucks to run up and down our highways. There is no reason that we can't engineer highly effient diesel powered generators, that would then power electric drive motors for our semi truck industry. To help reduce both fuel consumption and carbon output. Batteries might also be a viable cost effective option with this type of application, given all of the downhill braking that ...more »
DHHS Essential Services policy requires all threats to life and health be stopped and prevented. Wood smoke is 12 times more carcinogenic than tobacco smoke that is banned. It pollutes regions more than cars that are regulated. So require NSPS stds to meet EPA guidelines for a safe pm2.5 dose of raw wildfire and wood smoke at 180 mcg/m3,hr. It will help air quality, global warming, lower chemicals, clean up communities, ...more »
My comment is a question please. I get a lot of magazines with shiny pages. I am told not to burn them because they give off taxic gases because of the ink. I make biomass briquettes from shredded paper, grass clippings, and wood chips. Can I shred these shiny magazine pages to make briquettes for burning? Does the ink give off poison gases? firstname.lastname@example.org. thanks
are you guys doing anything about this? I'm deployed to Afghanistan and have to breath this in everyday because we are located close to the burn pit
