A lawsuit and dust-control measures aim to end the Oceano Dunes status quo
BY RHYS HEYDEN
Sand dunes are complicated, unstable, constantly shifting, and abrasive—a delight to some, and a nuisance to others.
Fittingly, all of those adjectives are equally suitable for describing the years-long dispute over the regulation of the Oceano Dunes State Vehicular Recreation Area.
At the heart of the debate is a coarse, airborne dust called PM10 (particulate matter with a mean aerodynamic diameter of 10 microns or less). Studies have shown that levels of PM10 on the Nipomo Mesa, a residential area downwind of the recreation area, are dangerously high, with the potential to adversely affect the health of residents.
While no one disputes the high levels of PM10, there’s tremendous disagreement over the source of the air pollution. After numerous studies, lawsuits, and highly public tiffs, stakeholders across the spectrum have, essentially, fought to an impasse.
In the past few weeks, however, an aggressive lawsuit from a group of concerned Mesa residents and emergency dust control measures approved for implementation by California State Parks have busted through the status quo, from opposite ends of the spectrum.
Though air quality advocates feel that the State Parks measures aren’t good enough, and off-highway vehicle (OHV) advocates feel that the lawsuit will be unsuccessful, both are steps in the direction of change.
“Controlling dust from the [recreation area] should just be a simple, regulatory matter, but it’s turned into an ugly political, litigious mess,” San Luis Obispo County 3rd District Supervisor Adam Hill said. “Unfortunately, there’s been a lot of heel-dragging with this situation.”
The matter of mitigating or not mitigating dust in the dunes has involved several key stakeholders: SLO County government, including the Board of Supervisors and the county Air Pollution Control District, State Parks, citizens living on the Nipomo Mesa, and off-highway vehicle advocates like the Friends of Oceano Dunes and Kevin P. Rice.
According to Arlene Versaw—co-founder of the Mesa Community Alliance, a nonprofit activist group said to represent the common interests of Mesa residents—the dust issue is very simple.
“There is a serious air quality problem here on the Mesa; the preponderance of evidence shows that the OHV area is a major cause of that problem, and we need to address the significant health threat,” Versaw told the Sun.
After growing frustrated with the unresponsiveness of State Parks and the county regarding the air quality issue and a years-long stalemate, the Mesa Community Alliance filed suit against those two bodies on Feb. 27 in San Luis Obispo County Superior Court.
The suit seeks to prohibit off-highway vehicle activities on the dunes until and unless State Parks “designs and implements effective mitigation measures to abate the particulate matter air pollution that is caused by the operation of the [recreation area].”
Though some have taken this lawsuit as evidence that the Mesa Community Alliance, Hill, and Air Pollution Control District Executive Director Larry Allen ultimately want to close down the recreation area, all three stakeholders vehemently denied that accusation.
“You can support the OHV recreation area and support mitigating dust pollution that is exacerbated by it,” Hill said. “It’s not an either/or proposition. I have always supported the OHV area, but I also believe it’s our legal and moral responsibility to protect the health of citizens on the Mesa.”
Hill, Allen, and Versaw said they’re all working in their separate arenas to ensure action on the air pollution issue as soon as possible.
On the other side of the issue, OHV activist Kevin P. Rice said he has manifold doubts and concerns about the dust control efforts.
“It’s not a bad thing to make the air quality better,” Rice said. “The question, though, is how far we should modify, impact, or destroy the natural state of the dunes for the benefit of the residents of the Nipomo Mesa.”
Rice questions the tactics of the Air Pollution Control District and the Mesa Community Alliance at almost every turn. He claims that the science establishing off-highway vehicle activity as a major air polluter is shoddy, says the district has ignored other viable causes of air pollution (local construction, deforestation, and ocean-borne PM10 among them), and maintains that both organizations have cherry-picked facts and arguments that support what he says is their ultimate goal: closure of the recreation area.
“Though it doesn’t stand an ice cube’s chance in hell, I’m happy for the MCA’s lawsuit,” Rice said. “The more the issue is debated, the more the facts will come out. Eventually, the county will realize that the world isn’t flat.”
While disagreements between OHV advocates like Rice and environmentally focused organizations like the Air Pollution Control District and Mesa Community Alliance are well-worn and seemingly intractable by this point, State Parks is focused on recently approved emergency dust control measures to move toward change in the dunes.
According to Oceano Dunes District Superintendent Brent Marshall, his district was able to secure an emergency permit from the Coastal Commission in mid-March that will allow for the installation of wind fencing and hay bales in the dunes to cut down on PM10 pollution.
“It’s a massive project with lots of moving pieces, equipment, people, and we’ve been working on it for about six weeks,” Marshall told the Sun. “We can help our downwind neighbors this way, and accomplish our goal of making the air safer.”
Marshall said that, starting March 17, workers will be installing 30 acres of hay bales in a grid and also erecting several long lines of 4-foot-high, meshed plastic wind fencing. Both measures are designed to slow down and disrupt winds traveling on the surface of the dunes, and newly-installed monitors will assess the success of these efforts.
Though Marshall said he hopes for a significant PM10 pollution reduction, Versaw and Allen said that State Parks’ dust control measures—which are only permitted through the end of June—are merely a good first step, and don’t go nearly far enough to adequately control dust and protect Mesa residents.
“It’s discouraging to see this dust control work be disparaged before we’re even starting,” Marshall said. “If someone can do it better than we’ve done it, then I’d like to see that. It might not ever be enough for activists, but we’re doing what we can.”
As State Parks’ dust control measures and the Mesa Community Alliance lawsuit both press for change, the looming deadline for all stakeholders is May 31, 2015. At that date, the APCD’s controversial “dust rule”—enacted in November 2011 and upheld in court after challenges from Rice, Friends of Oceano Dunes, and State Parks—will go into full effect.
If PM10 levels on the Mesa still exceed state standards at that point, the dust rule, according to Allen, gives the APCD the ability to penalize State Parks using a “toolbox” of penalties, ranging from discussions to re-evaluations to costly fines of up to $1,000 per day.
“We’re interested in results, not money from State Parks,” Allen said. “There’s a significant public health threat that needs to be resolved.”
For now, mediation is ongoing between all the stakeholders—both in courtrooms and boardrooms—as it has been since 2010, when studies first identified the Mesa’s air quality problem.
“It’s taken a lot of time to work through this mediation process,” Allen said. “We believe that we are getting very close to the end.”
