WASHINGTON — The Environmental Protection Agency has proposed several amendments to standards related to nutritional yeast manufacturing, including revising the form of the fermenter volatile organic compounds (V.O.C.) emission limits, changing the testing and monitoring requirements, and updating the reporting and recordkeeping requirements.

The proposed amendments to the National Emission Standards for Hazardous Air Pollutants for the Manufacturing of Nutritional Yeast source category are in the Dec. 28 issue of the Federal Register and may be found here.

One amendment proposes that 100% of fermentation batches meet the fermenter batch average V.O.C emission limits on a 12-month rolling basis. The E.P.A. said the current requirement of 98% conflicts with the statutory requirement that emission standards apply at all times, as discussed in the court case “Sierra Club v. EPA. 551 F. 3d 1019 (D.C. Cir. 2008).”

Another proposed amendment includes an alternative compliance method that allows facilities to average the V.O.C. concentration data from all batches within each fermentation stage over a rolling 12-month period.

The E.P.A. proposed to revise the rule’s testing, monitoring, recordkeeping and reporting requirements in five ways:

Owners or operators must demonstrate compliance by using a V.O.C. continuous emission monitoring system (C.E.M.S.) to determine the V.O.C. concentration in the fermenter exhaust;

Owners or operators may not use a gas chromatographic C.E.M.S. to monitor V.O.C. concentration;

Owners or operators must have valid C.E.M.S. data from each hour of the entire batch monitoring period and report periods of missing data as deviations;

Owners or operators of V.O.C. C.E.M.S. must conduct annual performance tests; and

Owners or operators must provide compliance reports electronically.

The E.P.A. also proposed to remove the option to monitor brew ethanol.

The E.P.A.’s manufacturing of nutritional yeast source category includes any facility engaged in the manufacture of baker’s yeast by fermentation (both active dry yeast and compressed yeast). The category includes, but is not limited to, these manufacturing process units: fermentation vessels and the drying and packaging system.

The E.P.A. will accept comments on its proposed amendments until Feb. 13. Comments identified by Docket ID No. EPA-HQ-OAR-2015-0730 may be submitted at www.regulations.gov. The E.P.A. said a public hearing will take place if it is requested by Jan. 3.

I just wonder what the National Emission Standards for Hazardous Air Pollutants for the meat, dairy, and poultry industries look like....double standards????

By Murray Noseworthy 1/22/2017 6:57:32 AM
Why is the EPA targeting this product for emissions when animal agriculture is by far the greatest source of pollution in the USA? Is this a backlash against the vegan community who is uncovering the atrocities of factory farming which destroys lives and the environment. The emissions from the manufacture of nutritional yeast is almost irrelevant compared to that. Is this a big ag initiative?

By Jennifer Norvesh 1/22/2017 6:27:15 AM
I will not reiterate the comments below (i agree with them whole-heartedly). My concern us that the EPA couldn't find anything else to go after besides nutritional yeast? Really! I understand that the meat and dairy industry is probably too big for them to go after (which is scary enough) but really... nothing else is causing major environmental issues but yeast? This load of BS puts the cesspools on farm factories to shame!

By Amanda Walters 1/22/2017 12:56:32 AM
Would be more logical to address the much larger pollution causing food items....Like meat and dairy. Factory farming is a much bigger problem than nutritional yeast. Work for the good of the public not corporations.

By Shannon Blair 1/22/2017 12:42:21 AM
This has got to be a joke. #GoVegan

By Abigail Bagnall 1/21/2017 5:02:17 PM
These proposals are a direct attack on the vegan movement oh-so-thinly disguised as environmental protection. We urgently need to address the livestock industry's emissions and pollution. Until we do that we are fiddling whilst Rome burns.

By Leslie Cunningham 1/19/2017 12:50:19 PM
I am all for reducing pollution, but let's target a much more egregious source first: factory farming of animals.

By Shayne O'Brien 1/13/2017 3:32:53 PM
Please turn your attention to animal agriculture as a priority.

By Rachel Phillips 1/13/2017 2:25:02 PM
This is insane. Why don't we crack down on the animal agriculture industry which we know for a fact is a massive pollutant across the world. This just goes to show how the government has no public interest at all, they are just interested in preserving big corps destroying the planet for profit.

By Gerry Wagoner 1/12/2017 8:06:16 PM
This is absolutely stupid. Here we have evidence of a layer of bureaucracy seeking to validate itself through ridiculous regulations. Vegans are the most efficient consumers on the planet. Leave this organic product alone.

By Linda Speel 1/12/2017 3:36:21 PM
My family has used nutritional yeast for 40 years in our diet. Please don't make it harder to manufacture!

By Sara 1/12/2017 12:23:37 PM
I feel like this is a little far fetched. The meat industry produces more methane and greenhouses gases then all transportation. Let's put them under the microscope as well.

By Andrea 1/12/2017 8:37:43 AM
This is unacceptable, when one of the BIGGEST greenhouse gas emitters, water polluters, ecosystem distructors, ocean and wildlife killers is the animal product industry. How about you address the biggest issue first by putting restrictions on the amount of pollution factory farms create. Then you can talk about nutritional yeast.

By Anahit Ohanjanyan 1/12/2017 7:07:43 AM
Out of all the big problems that we have today - animal agriculture contributing 51% to greenhouse effect,contamination of water all over the country,air polluted by chemicals dumped from planes ( weather modification) you decided to concentrate on how yeast is brewed... Its a pathetic and cunning way to undermine vegan movement, which is doing more than you lately - as you prefer to ignore most problems. How about stop the production of superbugs by animal industry, creation of ocean dead zones and make the account for amount of methane released?

By Jody 1/12/2017 6:02:48 AM
Stop the fraud and inequality in the food industry where we murder and torture animals for food and are giving plant based food issues that are unnecessary. What is the concern? Where is the empirical evidence based on sound research that it's needed ? I object to this requirement !

By Dunlke 1/12/2017 3:43:05 AM
I would urge you to deal with the outrageous emissions caused by animal agriculture which exceeds the emissions put forth by transportation. Leave the yeast alone please.

By CL McKay 1/11/2017 11:27:53 PM
38,896 legalese words in the BS document and not an easy way for the average person to comment -- not that any comments will make one bit of difference. That's your bloated federal bureaucracy in action.

By Michelle MaBelle 1/11/2017 10:53:00 PM
Are you serious??? How about you look into factory farming??? The animal agriculture industry continues to emit more greenhouse gases than all of transportation combined. WHAT ARE YOU THINKING??? Leave Nutritional Yeast alone for Pete's Sake.

By Jarred vryhof 1/11/2017 9:13:24 PM
Is this where we comment on this nonsense? If you're attacking this, EPA, go after the top pollutants of this earth; meat, dairy, and poultry. Then come back to this. EPA has been a joke too long. Do your jobs like the world depends on it. Your children will thank you.

By Aly 1/11/2017 7:15:09 PM
..... you can't be serious.... going after a nutritional yeast plant for "emissions" is quite laughable if you compare it to, let's see, the agriculture business, the cattle business alone (that includes all the emissions alone to harvest crops for agri-animals)... leave those of us alone who wish to not consume dairy... every where I turn it's like big business and government are trying to force us to be consumers of that poison..... why does our lifestyles threaten you so much?

By Andrea 1/11/2017 6:58:52 PM
I don't really have anything to add to the other comments. I just want to add my voice to the others. Please go after the big polluters before regulating nutritional yeast production.

By Stephanie C 1/11/2017 6:54:14 PM
Please focus your attention to the greenhouse gases produced by large animal agriculture! Sure, it's important to monitor those produced from plants, however, our earth is being damaged by the huge cesspools on large animal agriculture farms. Priorities are important, go to the source of the true problems.

By Emily-May 1/11/2017 6:44:36 PM
If this is going to be an EPA standard for nutritional yeast (and if its emissions are truly damaging to the environment) then the same exact EPA standards should be used for ALL other pollutants including all agribusiness.

By Sonit Nangia 1/11/2017 6:30:09 PM
What about the toxic emissions from the animal factory farms?

By Thor Vanek 1/11/2017 6:28:28 PM
Please tackle the issue of greenhouse gas emissions caused by animal agriculture before attacking the production of nutritional yeast. Thank you.

By Amy Bressler 1/11/2017 6:10:55 PM
Animal agriculture is the #1 threat to our environment. That is the issue that needs to be addressed. Thank you.

By Moyra Mulholland 1/11/2017 5:46:36 PM
This is ridiculous! What about regulating the meat, dairy and egg industries? This is a blatant attack on the vegan movement.

By Moyra Mulholland 1/11/2017 5:40:48 PM
This is ridiculous! What about regulating the meat, dairy and egg industries? This is a blatant attack on the vegan movement.

By Michelle Westerkamp 1/11/2017 4:50:55 PM
This is ridiculous, it is already hard enough for people trying to eliminate GMOs, toxins and poisons from our diet and then you want to add extra regs to food producers making a difference. You should be regulating the meat industry where animals are abused and filthy meat is sold to the public as food. And then all the corn syrup, and other corn fillers put into so called food, its all poison, no one is eating real food anymore

By Lori Nero 1/11/2017 4:44:58 PM
seriously? You want to make a major impact on our cleaning up and making our environment safe, you need only look at the animal agriculture industry. For petes sake, this is seriously petty in the scheme of things...Total waste of funding. Please do something to create real change.

By Wendy 1/11/2017 3:09:32 PM
The EPA should be spending its time and energy on areas that have caused widespread illness, environmental damage, etc. Why spend time and money on yeast production when animal agriculture is FAR MORE DANGEROUS and has caused so much more trouble to the consumer. This is ridiculous.

By Dorie W 1/11/2017 2:22:26 PM
If this is going to be an EPA standard for nutritional yeast (and if its emissions are truly damaging to the environment) then the same exact EPA standards should be used for ALL other pollutants including all agribusiness, vehicle emissions, and the emissions produced by the meat industry. I am all for regulations to protect our environment, but this seems like stepping over dollars to get to pennies here.

By DK 1/11/2017 1:55:59 PM
Rein in the dairy, meat and fracking industries which cause more air and water pollution than transportation emissions instead of going after the small nutritional yeast industry. The effect of which will be miniscule in terms of environmental protection. Focus on the biggest offenders. Get your priorities in line.

By Matthew Curran 1/11/2017 1:15:46 PM
This is ridiculous. As all of my fellow consumers below have stated: we know who has power in the EPA. And it's not in the benefit of the citizens here in the US. It's agribusiness and industry calling the shots. So maybe you should concentrate your energies on them, instead of the small population of vegetarian and vegans whom use this beneficial product.

By Eve 1/11/2017 12:09:28 PM
Why try to control an industry that isn't harmful and not better regulate the worst polluters? This is a waste of time where urgent matters abond.

By Julia K 1/11/2017 11:48:09 AM
Why work so hard to regulate an industry that hasn't caused mass food illnesses, and hasn't destroyed our environment, while letting industries that DO kill people and the environment just slide? Maybe more concern should be placed where things like food poisoning and toxic factory practices are commonplace, like the meat industry.

By BRITT SHEA 1/11/2017 11:24:37 AM
What a bunch of BS!!!! We need to worry about real things and real impacts on the environment! Pull your head out of your rectum!

By Crystal Teegarden 1/11/2017 11:22:53 AM
I'm curious why the E.P.A is choosing to spend their efforts monitoring nutritional yeast when there are much bigger issues out there concerning public health. Why not ask factory farmers to reduce their ridiculously high volumes of pollution? THAT would actually be beneficial to our environment much more than spending energy on nutritional yeast.

By Kelly Tope 1/11/2017 11:11:54 AM
It is shocking that the EPA chooses to focus on Nutritional Yeast instead of regulating the pollution from animal agriculture that destroys our environment on a daily basis. Interesting to see what groups the EPA works to protect. Clearly Big Ag has their hooks in the EPA along with the rest of the government.

By Lisa shoaf 1/11/2017 10:49:53 AM
This is ridiculous. How is nutritional yeast harming the environment? Shut down all meat production and factory farms and breweries first!

By Vannesa shanks 1/11/2017 10:40:28 AM
Please focus on the environmental destruction being wreaked by meat processing and its standards and leave the focus off an industry that is small, caters to the needs of a few, and it's potential to cause harm is negligible, especially in comparison to big farming industries.

By Jody Kraner 1/11/2017 10:36:35 AM
Perhaps the EPA should focus on something that is destroying the environment: cesspools from factory farm operations! something affecting our water!!!!!!!!!! in vast quantities. This is ridiculous to focus on something so small.

By Johanna Martin 1/11/2017 10:18:52 AM
PLEASE leave the miniscule nutritional yeast industry alone and put your efforts where it WILL DO MORE GOOD: the meat and dairy industries which make more pollution than all transportation combined.

By Matea Zajec 1/11/2017 9:38:37 AM
To whom it may concern, Nutritional yeast is an incredibly healthy nutritional supplement, used by a very small population, mainly people on a special, vegetarian and vegan diet. It seems like a very small product to focus on, and also a product used by a very specific group of people who are continuously begging the EPA to consider diminishing animal agriculture and it's disastrous effects on planet Earth, the economy, and the animal population. The animal agriculture industry continues to emit more greenhouse gases than all of transportation combined, but somehow it is more than welcomed to continue polluting the environment, what to speak of killing billions of innocent animals. As a consumer of nutritional yeast, I plea you stop your efforts to put obstacles on it's production, and consider diminishing the negative effects of the meat and dairy industry. Thank you.

By Vel lauterio 1/11/2017 9:12:16 AM
his is what the EPA decides to crack down on? You're not going to crack down on the environmental pollution that's caused by the factory farms or even by the little local Farmer? This is absolutely ridiculous! Maybe if the meat and dairy industry didn't own the EPA, they would work on the real issue of animal agriculture.

By TJay 1/11/2017 9:00:05 AM
I think your focus should be on the Animal Agricultural industry... Not this!

By Beth Skeen 1/11/2017 8:56:26 AM
If EPA is going to "crack down" on the manufacturing of nutritional yeast due to their "concerns" in regard to emissions....then I assume they will also most certainly be looking into "cracking down" on the 400 !! different harmful gases released into the atmosphere ( like e nitrous oxide, methane, carbon dioxide, ammonia and hydrogen sulfide.Toxic Gases) from factory farm waste?

By Jessica I Stapp 1/11/2017 8:37:18 AM
The VOC emissions are negligible compared to the environmental destruction caused by animal agriculture. Animal agriculture snuffs out biodiversity, takes up many acres of land to house animals (not to mention the feed for those animals which is about 70% of what is grown), and creates cesspools of biohazard waste material nobody knows how to get rid of. The only solution (sprinkling it into the air) is causing enormous health problems for people living near these farms. Please be smart and turn your attention to animal agriculture.

By Laryssa cooprider 1/11/2017 8:31:29 AM
EPA needs to fist address the animal impact on greenhouse emissions. Animal agriculture is of far more concern than nutritional yeast production. Which benefits the plant based community.

By Jill Tinsley 1/11/2017 8:17:46 AM
The EPA needs to target the animal agriculture industry as it continues to emit more greenhouse gases than all of transportation combined.

By JWilkinson 1/11/2017 8:13:39 AM
The EPA's first focus should be on the agriculture industry (factory farming) and the extreme destruction it causes before this.

By Amanda L Kraenzle 1/11/2017 7:59:16 AM
The animal agriculture industry continues to emit more greenhouse gases than all of transportation combined and they are concerned about emissions from YEAST? Absolutely ridiculous.

By Amber Campbell 1/11/2017 7:56:29 AM
This is what the EPA decides to crack down on? You're not going to crack down on the environmental pollution that's caused by the factory farms or even by the little local Farmer? This is absolutely ridiculous! Maybe if the meat and dairy industry didn't own the EPA you would focus your work into doing good rather than what you're doing now. This is unbelievable!

By Maya Annaby 1/11/2017 7:41:42 AM
Please hold off on adding regulations to nutritional yeast manufacturing! Focus instead of adding regulations for products that cause significant levels of environmental damage, like animal (by)products !

No Profanity Allowed, Please Retype Your Comment.

By Jacqueline Eidelson 1/11/2017 7:31:00 AM
Please don't add more "regulations " to yeast!ll To think that makers of fermented yeast are or could possibly cause more greenhouse gases than say beef is just absurd. If you really make a difference regulate factory farming.
