Indivisible on Offense: A Practical Guide to the New, Democratic House

Rachel Maddow hosted an important interview last night with Ezra Levin, co-author of the Indivisible Guide.  Her 5-minute interview and the new Indivisible on Offense: A Practical Guide are exciting introductions to the work ahead in these next two years.

Main premise: Now that Democrats have taken control of the House, we are no longer ONLY playing on defense; we can now set agendas, advocate for new legislation and powerful oversight moves.  The guide is a powerful tool for everyday folks like you and me.

My New Pollution Monitor: Gimmick or Game Changer?

By  Meredith Fowlie, January 2, 2019

The sensor revolution takes on air pollution

A few months ago, our family invested in our own air quality monitor. This little sensor has made invisible air pollution visible. And it’s changing the way we think about the air we breathe.

Turns out, we’re not the only ones geeking out on home pollution monitoring. Here in California, private citizens have deployed more than three times as many air pollution sensors as the government agencies charged with the task of monitoring our air quality. The graph below tracks the adoption of PurpleAir monitors like ours in Northern California.

Filling the monitor gaps

Once connected to Wi-Fi, privately owned PurpleAir devices feed into a global network and data are displayed in real time on a cool map. This enables a kind of public crowdsourcing of air quality information– an important shift away from the status quo.

State and Federal government agencies have traditionally been the primary/only source of air quality data. Public provision makes sense because we all benefit when people can access reliable air quality information. And if the benefits are shared by everyone, it follows that the costs should be shared as well.

But the high costs of monitoring have limited the scale of the public monitoring network. A single EPA air pollution monitor can cost as much as $100,000 to install and requires skilled staff to operate. On account of these high costs, there are fewer than 1000 regulatory grade air quality monitors measuring PM2.5 –the ultrafine particles that pose the greatest health risk –in the entire United States.

Sparse monitoring would not be a big issue if pollution concentrations didn’t vary much over space. But exposure to pernicious local pollutants like PM2.5 can vary significantly over short distances. If you live far from an EPA monitor, the crud in the air you’re breathing can be very different from the measurements used to monitor and enforce air quality regulations.

The upshot is that spatial gaps in the regulatory monitoring network leave wide gaps in our understanding/monitoring of air quality.  Cue the low-cost, “consumer-grade” sensor revolution. Companies like PurpleAir, Atmotube, and Plume Labsare putting air pollution monitors in the hands of private individuals and community organizations. And these little sensors are starting to fill some big gaps.

The map on the right plots the government-operated, regulatory-grade monitors where I live (the Bay Area). The map on the left is a recent snapshot of monitor readings from Wi-Fi connected PurpleAir monitors in the same area. Wow.

You might be concerned that you get what you pay for with these low-cost sensors. It’s true that PurpleAir sensors (and other consumer-grade sensors) use a different technology to count the tiny particulates in our air. Although this technology is not as reliable as regulatory grade monitors, our colleagues at the Lawrence Berkeley Lab have put these low-cost monitors to the test and found that PurpleAir sensors performed surprisingly well.

Information Drives Action

Our PurpleAir sensor cost us $210. That’s a lot less than $100k, but not a small price to pay to collect our own personal air quality information. We had three reasons for making this investment:

1. Particulate pollution is hyper-local: Living 3 miles from the closest government monitor, we were curious to get a better read on the quality of the air our family breathes every day. We live far from a major road, so we are fortunate to breathe air that seems generally cleaner than the closest EPA monitor records for regulatory purposes. Others are not so lucky. Nearby (indoor) PurpleAir (PA) monitors located downwind of a major highway seem to read consistently higher.

2. We live indoors: Most of us spend most of our time indoors. It is, therefore, remarkable that the health effects of indoor air pollution are relatively poorly understood. Almost everything we know about the health effects of pollution exposure is based on outdoor pollution monitor measurements. Until we installed our PA monitor, I didn’t think much about indoor air quality.

My assumption was that if pollution particles are impossibly tiny, they must pass easily between indoors and outdoors. And so PM2.5 levels should be more or less the same indoors and out. Turns out that assumption is not quite right. The graph below plots hourly PM2.5 concentrations inside our house (blue) and at the closest outdoor PA monitor installed less than a mile away (orange).

In the first couple of months after installing our sensor in September, particulate concentrations inside our house tracked outdoor air quality fairly well. But you can see instances when our air quality is worse than outdoors. Reasons include: stovetop popcorn, forgetting to run the stove vent while cooking dinner, and our third grader’s science experiment run awry.

But then came the Camp Fire in November. Northern California was mired in awful smoke for over a week. Outdoor particulate concentrations reached dangerous levels. Initially, our indoor air quality climbed in lock-step with outdoor air quality. But with the help of our PA monitor, we started experimenting. Real-time monitor feedback helped us figure out what was working (replacing our furnace filters and running the fan 24/7) and what was making things worse (running our kitchen stove vent which pulled outside air in).  We managed to improve our indoor quality considerably while the outdoor air quality remained terrible.

3. Citizen science/environmentalism/data nerdism

When the government is the sole provider of air quality information, the government gets to choose where and how air quality gets measured.  Recent research by some of our colleagues highlights some concerning aspects of the where and how of past air quality monitoring activities. As for the current administration, the Trump EPA has been working hard to downplay concerns about air pollution and reduce the stringency of air pollution regulations.

If you find all of this very concerning, a consumer-grade air pollution monitor gives you a way to increase the level of publicly available air quality information and scrutiny. Ever since we connected our monitor back in September, we’ve been transmitting high-resolution information on local air quality, displayed in real time via a user-friendly air quality map for all to see. The effect we are having may be incremental, but the aggregate impact of widespread adoption could be significant.

Gadget or Game Changer?

The growing popularity of low-cost sensors is exciting. But a few thousand sensors operated by the likes of me does not a revolution make. If these little sensors are going to be transformative, they’ll need to be more widely deployed. And the data need to be actionable so that people can understand where the most dangerous pollution problems manifest and how we might address them.

We’re already seeing some exciting grassroots and green shoots initiatives. In the year ahead, we should see a lot more. California’s AB 617 mandates that community-level air monitoring be put in place by mid-2019. To keep implementation costs manageable, low-cost sensors will likely play an important role. The specifics of that role still need to be worked out. Low-cost sensors are no perfect substitute for regulatory-grade monitors. But they could be important complements. If well-crafted policy implementation and community mobilization can catch up with sensor technology innovation, these cool gadgets could become a real game changer.

Benicia’s Campaign Fairness Ordinance; Can We Make it Better?

Benicia’s Campaign Fairness Ordinance; Can We Make it Better?

City Council Decides to Take a Look

By Ralph Dennis

Larnie Fox, a PDB member, sent a note out recently through Benicia Resist! mentioning City Council’s decision, unanimously, to agendize a discussion of a possible strengthening of our local campaign fairness ordinance. He included this bit from the agenda:

“Council member Tom Campbell submitted a two-step process request on November 15, 2018 for Council consideration of possible changes to the campaign ordinance. This Request is to determine whether or not the Council would like to agendize the topic for discussion at a future Council meeting.
Recommendation: Discuss the request and provide direction to staff.”

Larnie encouraged all Benicia Resisters! to show up in January. We should all show up at the January City Council to support efforts to disallow the dark tactics, as Larnie described, that Valero used during the recent election.

I would add, that there isn’t much, if anything, we can do about the amount of money coming in, if someone wants to do it, due to the Citizens United Supreme Court ruling in 2008. But, Benicia does have its campaign ordinances, and one that already requires information to be filed by the dark tactics players; and, even those players made the required filings this past election. It wasn’t enough, of course.

So, maybe something can be done to tighten up the ordinance itself. Councilman Campbell alluded to this while discussing his request. As an example, if the City can’t make the pollsters divulge who paid for the polling because it would bias the poll, then maybe we can require that information, say, 48 hours after the poll is conducted. His self-described goal: make sure the voters know “when they step into the voting booth” who is backing each candidate.

It occurs to me as I write this, and after reviewing the actual request from Councilman Campbell and Benicia’s municipal code’s campaign ordinances: I wonder if we know which ordinance we’re taking a look at? Or, are we looking at all of them? The City Attorney’s letter sent back in September to the pollsters, mentioned that “the city has several campaign ordinances.” And, by example, referred to Benicia Municipal Code Section 1.40.042 which requires certain disclosures for campaign communications funded by independent expenditures. This sounds like the one Campbell is after.

We shall see what happens, but at least here is an opportunity to do something, perhaps.

When? I couldn’t find the Council’s official 2019 agenda schedule, apparently it is not posted yet on the City’s web site. However, I asked Steve Young, who said that Council will meet on Jan. 15 and Jan. 22.

Which meeting? At the Council meeting, City Manager Lorie Tinfrow said this item will be on a January agenda, but did not indicate then at which meeting. I think we should know soon, though, and we’ll let you know once the date is set. Check the PDB web site for updates!

Our next meeting is Jan. 8. We’ll discuss this item during the meeting.
