The US Environmental Protection Agency is considering RAISING the allowable amounts of radioactive emissions into the air and water from nuclear power plants! The EPA is proceeding with potential rule changes despite studies that show higher incidences of childhood leukemia repeatedly occur in children living near or downwind of nuclear power plants.
Here is the EPA link on its proposal to raise allowable levels of exposure to powerplant radiation:
Particularly dangerous is tritium, a radioisotope that is routinely released from operating nuclear plants. Tritium, which is too small to be contained by reactor filters, can end up in the rain and snow (and therefore our food and drinking water).
Tritium exposure is particularly hazardous for children since it is capable of crossing the placental barrier (See: http://www.ccnr.org/tritium_1.html) and, consequently has been linked to birth defects in newborns.
The EPA is asking for public comment on the proposal to increase the “safe” level of radiation exposure. Public comments will only be accepted until August 3, 2014.
ACTION ALERT: Please submit a comment to the EPA expressing your concern. The online comment process is simple and can elect to remain anonymous. Here is the EPA link for accepting public comment on this:
EPA Wants My Opinion?
Well, Here It Isâ€¦
Joy Thompson / Enformable
(July 2014) — The Environmental Protection Agency — the overseers of the suspiciously on-again/off-again RadNet monitoring system in the wake of the 2011 mass meltdown/blow-outs at Japan’s Fukushima Daiichi power station — has helpfully extended the public comment period on its proposed “update” to 40CFR.190, “Environmental Radiation Protection Standards for Nuclear Power Operations.”
Citizens now have until August 4th to submit their comments on exposure limits, dose calculations, new fuel cycle technologies and related topics.

Advance Notice of Proposed Rulemaking (ANPR).
The EPA is seeking public comment and information that they may or may not use for planned updates to the old rules for Environmental Radiation Protection issued in 1977, ostensibly to make them easier to understand and implement. Given how often the public is treated to professions of ignorance from the nuclear industry (such as, “we don’t know how to measure beta radiation levels!” when caught disseminating blatantly false data), this could be a good thing.
The Nuclear Regulatory Commission [NRC] is responsible for implementing and enforcing the standards established by the EPA, and we have watched with some jaded dismay as NRC has steadily abdicated its responsibilities, entrusting them to the utilities it’s supposed to be regulating. Utilities now enjoy little to no oversight or auditing of their monitoring or records, and requirements for public notification and protection (like evacuation of nearby residents if releases reach certain levels) have been demonstrated pointless because they are routinely ignored. Perhaps if EPA can tweak its rules so that even the NRC can understand them, we could expect much better compliance all around.
The original rules were developed in the mid-1970s under the presumption that in the ensuing 20 years US nuclear generating capacity would triple to more than 300 gigawatts (US capacity peaked at 101 gigawatts). That has not happened and isn’t going to happen, as the costs have spiraled out of all reasonable bounds and the risks have become increasingly evident to the public.
The original rules also depended upon the continued existence and steady expansion of fuel reprocessing, and the eventual existence of medium and long term repositories for disposal of spent fuel and other high-level nuclear waste. No such repositories exist to service the commercial power industry 40 years later. Now, however, the EPA has convinced itself that it’s all going to magically happen in the immediate future, so it needs to develop new rules for these efforts and for decommissioning/cleanup of plants no longer in service.
To help interested people who may be confused by the technical gobbledygook that frames the issues in the EPA’s documents, I am listing the issues here, offering an abbreviated look at EPA reasoning in presenting these issues for comment, and supplying my own responses to the questions EPA is posing to the public.
Because no new rules have yet been formulated and submitted, it’s difficult to tell how any specific changes might affect NRC enforcement, industry compliance, or the environment and public health. We are forced to sort of “read between the lines” while keeping in mind what we have learned through the decades about the industry in all stages of the nuclear fuel cycle, as well as government’s poor record in the realms of regulation and enforcement.
Issue 1: Consideration of a Risk Limit to protect individuals. Should the Agency express its limits for the purpose of this regulation in terms of radiation risk or radiation dose?
EPA limitations on most cancer causing substances are expressed in terms of risk to the exposed public of developing cancer over time. This risk is a statistical exercise — averages divvied across populations — and easy to ‘fudge’ simply by adding more people to the risk pool. It works like this: Your reactor has a burp, releases 100 curies of iodine-131 out the station vent stack over a given length of time. 50 people live within 3 miles of the reactor and another 150 people live in the plume path to 20 miles distance.
Let’s say those 200 individuals are calculated to receive effective thyroid doses in the 3-5 Rem range over the duration of the exposure. As it now stands, the utility would be required to put its emergency evacuation plan into effect and activate the local responders to get the people most at risk out of harm’s way.
Under a risk model, the 100 curies of iodine would be divvied evenly among all the people the facility is able to claim as members of its risk pool. Let’s say that’s everyone who lives within 50 miles of the reactor plant, in any direction. Let’s also say that amounts to a total of 2 million people.
The statistical exercise would produce perhaps 200 additional cancers over the following decades in that total population, and the EPA might well consider the risk of 1 cancer in 1,000 exposed people to be an acceptable risk when weighed against the benefit of electrical power. That the 200 additional cancers would be in the 200 people the utility and regulators knew all along were exposed to high thyroid doses from the plume, would of course go unnoticed and unremarked.
The diluting of those high doses with 1,999,800 people who were not exposed to the plume of radioactive contamination at all would serve to shield the utility from liability for those who were harmed, and reinforce the “No [Immediate] Danger To The General Public” lie.
Don’t dismiss that scenario — it happened just that way at TMI2 back in 1979 when dozens of detailed plume maps generated from helicopter monitoring in the first weeks magically got ‘disappeared’ when the government’s official investigation got underway. The Kemeny Commission’s Health Physics Task Force really did draw a 50-mile radius circle around TMI, included an additional ~2 million people in a statistical ‘risk pool’ who were not exposed to the plume, and delivered a totally bogus ‘conclusion’ that no one got enough of a dose to cause harm.
Because this sleight of mind has actually occurred for the purpose of covering up real harm to real people during the worst civilian nuclear accident this nation has experienced, we have no legitimate reason to expect that making this statistical trickery into official EPA “radiation protection” policy is intended to protect anybody from radiation harm during any future oops the industry suffers.
We must remember that the EPA’s job is to protect the public from the nuclear industry, not to protect the nuclear industry from itself. And we must insist stridently that it do that job properly. Radioactive contamination moves in plumes. We know this from bomb testing back in the 1950s and ’60s. We know this from TMI2, we know this from Chernobyl, and we know this from Daiichi.
My Response to Issue 1:
Because both national and international radiation protection guidelines developed by non-governmental radiation experts such as the ICRP and the National Council on Radiation Protection and Measurements recommend that radiation exposure standards be established in terms of dose to members of the public, the EPA should continue to base its limits on effective dose to members of the public.
Issue 2: Updated Dose Methodology (dosimetry). How should the Agency update the radiation dosimetry methodology incorporated in the standard?
EPA wants to go with the ICRP’s “effective dose” methodology that weighs damage factors so that doses to the public can be expressed without additional qualifications. This makes the statistical exercise of basing dose limits on a risk model easier. It also makes it easy for the people doing the radiation monitoring and dose calculations to cheat, but no rule or regulatory detail is ever going to prevent that in an industry born and bred in insular semi-secrecy and avoidance of responsibilities.
Current limits on exposures to the public during normal operation are 25mr [millirems] whole body, 75mr to the thyroid, and 25mr to any other organ, over a year’s time. There are no effective limits on accident releases, and anyone who followed the disaster at Fukushima in 2011 will understand why. If releases during an accident/event are calculated to deliver a set level of exposure [dose] to any member of the public over the duration of the event, the requirement for evacuation kicks in.
In the end, and given the past record of deception by the industry and its regulators concerning public exposures to radiation, it probably doesn’t matter which methodology is used to calculate and/or estimate doses to the public during a serious accident, so long as requirements for evacuation of the public when a certain set dose level is reached remain in place. That dose level should remain equivalent to the one(s) now in place.
My Response to Issue 2:
If using a more sophisticated method of calculating and estimating doses/harm to the public will make the task of radiation protection easier, there is no reason not to do so. If EPA decides to go to ICRP’s more recent methodology it should use the ICRP methodology that exists at present  and not the one ICRP might eventually quantify. Utilities should not be exempted from requirements for evacuation plans and notifications, nor should the allowable doses to the public be raised.
Issue 3: Radionuclide Release Limits. The Agency has established individual limits for release of specific radionuclides of concern. Based on a concept known as collective dose, these standards limit the total discharge of these radionuclides to the environment. The Agency is seeking input on: Should the Agency retain the radionuclide release limits in an updated rule and, if so, what should the Agency use as the basis for any release limits?
The original EPA release limits (Final Environmental Statement, 1976) were based on the assumption that spent fuel reprocessing would be the one area of the total fuel cycle that would release the most radionuclides to the environment. In 2014 we know from long experience with serious accidents, meltdowns and exploding reactor plants that the generation facilities themselves have proven to be the worst offenders.
We do not reprocess commercial spent fuel in this country, and haven’t done so since the 1970s. The government reprocessing facilities that do exist are notoriously filthy, as are fabrication facilities working with plutonium to make MOX fuels. Still, in overall environmental contamination, power plants suffering nasty “oopses” are right up there for consideration. And power plants suffering nasty oopses are not subject to radionuclide release limits because there is no way to stop those releases.
Now, however, we are looking at decommissioning aged and aging nuclear facilities, doing something with the accumulated tonnage of spent fuel waste, and applying release limitations to any/all new technologies that will come with future nuclear energy development (if that happens). Nuclear pollution from these activities must also be considered.
My Response to Issue 3:
EPA should continue to use the existing standards of limiting environmental burden as a guide, calculate and apply equivalent radionuclide standards for individual facilities at any stage of the nuclear fuel cycle.
This need not be based on estimated doses to the wider public or to individual members of the public. It does need to be recalculated as necessary whenever weapon/accident releases occur to release very large amounts of radionuclides to the biosphere, with an eye to maintaining a biosphere-wide environmental burden limit for all dangerous long-lived isotopes.
If such an effort ends up reducing the allowable radionuclide releases from any type of nuclear facility at any point along the fuel cycle to a level that cannot be reasonably applied, then those facilities should be closed and decommissioned. Humanity should not be asked to tolerate the nuclear pollution of our planet to the point where everyone’s health and longevity are materially compromised. If that means the end of the nuclear industry itself, then that’s what it means. Civilization can survive that just fine.
Issue 4: Water Resource Protection. How should a revised rule protect water resources?
Ground and surface water are necessary resources for organic life forms and entire ecosystems. EPA says it wishes to prevent water contamination rather than have to clean it up after it’s polluted. This is great. Existing standards don’t impose water-specific standards because nuclear plants do not release what they consider to be significant radionuclides to water sources during normal operation, and any such releases have had far less impact on public health than airborne releases. There are some fluid effluent limits for specific radionuclides.
As the industry’s facilities have aged, however, water pollution issues have come to the fore. Tritium contamination of groundwater, aquifers, rivers and lakes has become more problematic. Unfortunately, there are no technologies in existence that can effectively remove tritium from water. EPA wishes to establish off-site water standards commensurate with the Clean Water Act, which has specific limitations on concentration of carcinogens.
My Response to Issue 4:
The basis of any new EPA ground and/or surface water standards should be the limits specified in the Clean Water Act, diminished by the concentration of pollutants that may already be present in the water source. The dirtier the ground/surface water already is, the less any nuclear facility will be allowed to release. If the allowance goes to zero, the facility must be closed and decommissioned.
Issue 5: Spent Nuclear Fuel and High-Level Radioactive Waste Storage. How, if at all, should a revised rule explicitly address storage of spent nuclear fuel and high-level radioactive waste?
There are no long term geologic waste disposal facilities, nor adequate intermediate term waste storage facilities in this country. The failures of both Yucca Mountain and WIPP bode ill for any such facilities to be operational in the foreseeable future. Meanwhile the high-level waste is building up in spent fuel pools and 55-gallon drums at power plants and government facilities all over the place.
The disaster at Fukushima Daiichi has taught us a lot about how dangerous concentrations of spent fuel can be if there are coolant and/or circulatory disruptions and the zirconium cladding burns. Obviously, something has to be done about this situation as soon as possible. The question is whether or not that should be EPA’s job at this point in time.
EPA’s original 40CFR.190 did not directly address short-term on-site storage of spent fuel, as in those days spent fuel was not expected to be held in storage at nuclear facilities longer than 18 months anyway. The failure over the past 40 years to develop medium and long term spent fuel storage has turned operating nuclear plants into de facto storage facilities they were never designed to be.
Government/industry agencies, commissions, industry think tanks and international bodies can recommend the development of medium and long term storage facilities all they like. Fact is if nobody’s building them, they flat don’t exist and recommendations accomplish exactly zip.
If it ever looks like such facilities may at long last come to be, then the EPA may have a regulatory role in limiting the amount of radioactive substances those facilities can be allowed to release in any form to the environment. And those limitations can of course be based on either doses to the public or environmental burden to the biosphere, or both.
Since those types of limits are currently under discussion for these proposed new EPA regulations, it would seem that feasible limits for waste storage will already exist if/when storage projects get started. All the EPA needs to do if that ever happens is to assert them.
My Response to Issue 5:
The same limitations on releases to air and water from nuclear operations should be applied to on-site storage of spent fuel. There should also be a limitation on how much spent fuel can be stored in a single pool, as well as a time limit on how long it can stay there before being dry-casked.
The industry should be forced to dry-cask all spent fuel in their pools that has been stored for 2 years or more. Any dry cask storage facilities on-site should have an area radiation limit to protect workers, and should not contribute at all to off-site radiation levels.
Issue 6: New Nuclear Technologies — What new technologies and practices have developed since 40CFR.190 was issued, and how should any revised rule address these advances and changes?
It remains to be seen whether or not any ‘new’ nuclear technologies will ever get out of the starting gate in this country. Public opinion has turned firmly against expansion of the nuclear power industry, and given constant price inflation the technology will inevitably price itself right out of the market. Utilities can only charge so much for electricity. When the public can no longer afford to pay the bill, utilities will not be able to count on that income. If they deny electricity to that segment of their customer base, they won’t need all that gigawatt capacity either. It is highly unlikely that nuclear technologies will play much of a role in America’s energy future.
My Response to Issue 6:
Reality is that there is no pressing need for the EPA to develop separate or differing limits for possible future nuclear technologies that are entirely unlikely to be deployed. If any of them ever are deployed, the existing (or revised) standards should be applicable to any new nuclear technologies.
All applications involving nuclear fission should have to abide by the EPA protective regulations throughout the fuel cycle to limit harm to the general public, nuclear workers and the environment.
EPA should definitely develop and apply specific rules for MOX fuels as those are fabricated and used in power reactors. Plutonium is a dangerous radionuclide, as are other high energy alpha and beta emitters that occur during production, enrichment and fuel fabrication. Limits on levels and releases of these elements should be strict, and dutifully enforced.
I hope that concerned people will go through the ANPR and fact sheets for themselves and draft their own replies to EPA. Remember that these must be submitted by August 4th.
