WASHINGTON– Based on extensive recent scientific evidence about the harmful effects of ground-level ozone, or smog, EPA is proposing to strengthen air quality standards to within a range of 65 to 70 parts per billion (ppb) to better protect Americans’ health and the environment, while taking comment on a level as low as 60 ppb. The Clean Air Act requires EPA to review the standards every five years by following a set of open, transparent steps and considering the advice of a panel of independent experts. EPA last updated these standards in 2008, setting them at 75 ppb.

“Bringing ozone pollution standards in line with the latest science will clean up our air, improve access to crucial air quality information, and protect those most at-risk. It empowers the American people with updated air quality information to protect our loved ones – because whether we work or play outdoors – we deserve to know the air we breathe is safe,” said EPA Administrator Gina McCarthy. “Fulfilling the promise of the Clean Air Act has always been EPA’s responsibility. Our health protections have endured because they’re engineered to evolve, so that’s why we’re using the latest science to update air quality standards – to fulfill the law’s promise, and defend each and every person’s right to clean air.”

EPA scientists examined numerous scientific studies in its most recent review of the ozone standards, including more than 1,000 new studies published since the last update. Studies indicate that exposure to ozone at levels below 75 ppb — the level of the current standard — can pose serious threats to public health, harm the respiratory system, cause or aggravate asthma and other lung diseases, and is linked to premature death from respiratory and cardiovascular causes. Ground-level ozone forms in the atmosphere when emissions of nitrogen oxides and volatile organic compounds “cook” in the sun from sources like cars, trucks, buses, industries, power plants and certain fumes from fuels, solvents and paints. People most at risk from breathing air containing ozone include people with asthma, children, older adults, and those who are active or work outside. Stronger ozone standards will also provide an added measure of protection for low income and minority families who are more likely to suffer from asthma or to live in communities that are overburdened by pollution. Nationally, 1 in 10 children has been diagnosed with asthma.

According to EPA’s analysis, strengthening the standard to a range of 65 to 70 ppb will provide significantly better protection for children, preventing from 320,000 to 960,000 asthma attacks and from 330,000 to 1 million missed school days. Strengthening the standard to a range of 70 to 65 ppb would better protect both children and adults by preventing more than 750 to 4,300 premature deaths; 1,400 to 4,300 asthma-related emergency room visits; and 65,000 to 180,000 missed workdays.

EPA estimates that the benefits of meeting the proposed standards will significantly outweigh the costs. If the standards are finalized, every dollar we invest to meet them will return up to three dollars in health benefits. These large health benefits will be gained from avoiding asthma attacks, heart attacks, missed school days and premature deaths, among other health effects valued at $6.4 to $13 billion annually in 2025 for a standard of 70 ppb, and $19 to $38 billion annually in 2025 for a standard of 65 ppb. Annual costs are estimated at $3.9 billion in 2025 for a standard of 70 ppb, and $15 billion for a standard at 65 ppb.

A combination of recently finalized or proposed air pollution rules – including “Tier 3” clean vehicle and fuels standards – will significantly cut smog-forming emissions from industry and transportation, helping states meet the proposed standards. EPA’s analysis of federal programs that reduce air pollution from fuels, vehicles and engines of all sizes, power plants and other industries shows that the vast majority of U.S. counties with monitors would meet the more protective standards by 2025 just with the rules and programs now in place or underway. Local communities, states, and the federal government have made substantial progress in reducing ground-level ozone. Nationally, from 1980 to 2013, average ozone levels have fallen 33 percent. EPA projects that this progress will continue.

The Clean Air Act provides states with time to meet the standards. Depending on the severity of their ozone problem, areas would have between 2020 and 2037 to meet the standards. To ensure that people are alerted when ozone reaches unhealthy levels, EPA is proposing to extend the ozone monitoring season for 33 states. This is particularly important for at-risk groups, including children and people with asthma because it will provide information so families can take steps to protect their health on smoggy days.

The agency is also proposing to strengthen the “secondary” ozone standard to a level within 65 to 70 ppb to protect plants, trees and ecosystems from damaging levels of ground-level ozone. New studies add to the evidence showing that repeated exposure to ozone stunts the growth of trees, damages plants, and reduces crop yield. The proposed level corresponds to levels of seasonal ozone exposure scientists have determined would be more protective.

EPA will seek public comment on the proposal for 90 days following publication in the Federal Register, and the agency plans to hold three public hearings. EPA will issue final ozone standards by October 1, 2015.

Waste Water from Oil Fracking Injected into Clean Aquifers

California Dept. of Conservation Deputy Director admits that errors were made
By Stephen Stock, Liza Meak, Mark Villarreal and Scott Pham, 11/14/2014

State officials allowed oil and gas companies to pump nearly three billion gallons of waste water into underground aquifers that could have been used for drinking water or irrigation.

Those aquifers are supposed to be off-limits to that kind of activity, protected by the EPA.

“It’s inexcusable,” said Hollin Kretzmann, at the Center for Biological Diversity in San Francisco. “At (a) time when California is experiencing one of the worst droughts in history, we’re allowing oil companies to contaminate what could otherwise be very useful ground water resources for irrigation and for drinking. It’s possible these aquifers are now contaminated irreparably.”

California’s Department of Conservation’s Chief Deputy Director, Jason Marshall, told NBC Bay Area, “In multiple different places of the permitting process an error could have been made.”

“There have been past issues where permits were issued to operators that they shouldn’t be injecting into those zones and so we’re fixing that,” Marshall added.

In “fracking” or hydraulic fracturing operations, oil and gas companies use massive amounts of water to force the release of underground fossil fuels. The practice produces large amounts of waste water that must then be disposed of.

Marshall said that often times, oil and gas companies simply re-inject that waste water back deep underground where the oil extraction took place. But other times, Marshall said, the waste water is re-injected into aquifers closer to the surface. Those injections are supposed to go into aquifers that the EPA calls “exempt”—in other words, not clean enough for humans to drink or use.

But in the State’s letter to the EPA, officials admit that in at least nine waste water injection wells, the waste water was injected into “non-exempt” or clean aquifers containing high quality water.

For the EPA, “non-exempt” aquifers are underground bodies of water that are “containing high quality water” that can be used by humans to drink, water animals or irrigate crops.

If the waste water re-injection well “went into a non-exempt aquifer. It should not have been permitted,” said Marshall.

The department ended up shutting down 11 wells: the nine that were known to be injecting into non-exempt aquifers, and another two in an abundance of caution.

In its reply letter to the EPA, California’s Water Resources Control Board said its “staff identified 108 water supply wells located within a one-mile radius of seven…injection wells” and that The Central Valley Water Board conducted sampling of “eight water supply wells in the vicinity of some of these… wells.”

“This is something that is going to slowly contaminate everything we know around here,” said fourth- generation Kern County almond grower Tom Frantz, who lives down the road from several of the injection wells in question.

According to state records, as many as 40 water supply wells, including domestic drinking wells, are located within one mile of a single well that’s been injecting into non-exempt aquifers.

That well is located in an area with several homes nearby, right in the middle of a citrus grove southeast of Bakersfield.

This well is one of nine that were known to be injecting waste water into “non-exempt” aquifers. It’s located just east of Bakersfield.

State records show waste water from several sources, including from the oil and gas industry, has gone into the aquifer below where 60 different water supply wells are located within a one mile radius.

“That’s a huge concern and communities who rely on water supply wells near these injection wells have a lot of reason to be concerned that they’re finding high levels of arsenic and thallium and other chemicals nearby where these injection wells have been allowed to operate,” said Kretzmann.

“It is a clear worry,” said Juan Flores, a Kern County community organizer for the Center on Race, Poverty and The Environment. “We’re in a drought. The worst drought we’ve seen in decades. Probably the worst in the history of agriculture in California.”

“No one from this community will drink from the water from out of their well,” said Flores. “The people are worried. They’re scared.”

The trade association that represents many of California’s oil and gas companies says the water-injection is a “paperwork issue.” In a statement issued to NBC Bay Area, Western States Petroleum Association spokesman Tupper Hull said “there has never been a bona vide claim or evidence presented that the paperwork confusion resulted in any contamination of drinking supplies near the disputed injection wells.”

However, state officials tested 8 water supply wells within a one-mile radius of some of those wells.

Four water samples came back with higher than allowable levels of nitrate, arsenic, and thallium.

Those same chemicals are used by the oil and gas industry in the hydraulic fracturing process and can be found in oil recovery waste-water.

“We are still comparing the testing of what was the injection water to what is the tested water that came out of these wells to find out if they were background levels or whether that’s the result of oil and gas operation, but so far it’s looking like it’s background,” said James Marshall from the California Department of Conservation.

Marshall acknowledged that those chemicals could have come from oil extraction, and not necessarily wastewater disposal.

“But when those (further) test results come back, we’ll know for sure,” Marshall said.

When asked how this could happen in the first place, Marshall said that the long history of these wells makes it difficult to know exactly what the thinking was.

“When you’re talking about wells that were permitted in 1985 to 1992, we’ve tried to go back and talk to some of the permitting engineers,” said Marshall. “And it’s unfortunate but in some cases they (the permitting engineers) are deceased.”

Kern County’s Water Board referred the Investigative Unit to the state for comment.

California State officials assured the EPA in its letter that the owners of the wells where chemicals were found have been warned and could ask for further testing of their drinking wells.
