Just read recommendation to allow E15 fuel to be sold. Yes you say it is for 2001 or later highway vehicles. Do you assume that retailers can afford the tanks and pumps to also carry fuel for older and Marine products? Is it cheaper or more expensive for refineries to blend several types of fuel rather than one? Whats happens when the public realizes that they get less fuel Mileage on E fuel? When we figure out how to ...more »
Improving Air Quality
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 »
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 »
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
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 »
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 »
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
An important issue to consider for improved air quality is transportation in daily commuting to work. This implies cracking the solo-driving conundrum. Recently, the Bay Area suggested to tax drivers up to 10 cents per mile to ease traffic and pollution. On the contrary, instead of increasing taxes, we suggest to reduce costs and reduce spending by encouraging employees, employers and their businesses to use alternative ...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.
Idle start/stop systems shut a car down when it is idling. Since idling causes unnecessary emissions, why not do more than encourage drivers not to idle?
Some cars already have this technology, such as Toyota Prius and Mini Cooper. And some car manufacturers are already planning on using this for all their cars in the future, such as Mazda and Ford. We should require it of all new cars.
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 »
