COMMENTS TO BOCC ON O&G EMISSIONS NORTHEAST OF FORT COLLINS

On Tuesday, September 28, Doug Henderson delivered these remarks in the Administrative Matters meeting of the Larimer Board of County Commissioners. Tim Gosar, Gayla Martinez, Cory Caroll, and Jonathan Singer (LOGIC’s new executive director) also made comments to the Board:

Good morning Commissioners,

In a Tues morning BoCC meeting in June, we addressed the problem of
harmful, often illegal, emissions from oil & gas facilities – emissions
that damage people’s health, degrade air quality, and gravely harm our
planet’s climate.

We presented evidence about such emissions from a Prospect Energy
facility northeast of Fort Collins, including imaging of the emissions
taken by Earthworks in January and March 2021. A local resident also
told of his experience, health impacts, and harm suffered for years from
toxic emissions from this facility.

After the January investigation by Earthworks, a complaint was submitted
to the state, and Prospect subsequently said it had stopped the leaks
and emissions.

The next investigation in March showed that the facility was still
leaking, and another complaint was submitted to the state.

Prospect then actually made some repairs, and the leaks and emissions
stopped. At least temporarily.

But before long, local residents again were suffering from emissions
from this facility. So in early September, Earthworks investigated
again. Here is video from that investigation – which shows the facility
was leaking again

The illegal emissions documented in January, March, and September this
year are not the first. CDPHE cited Prospect last November for
regulatory non-compliance and illegal emissions at this facility – for
violations documented in November 2018, June 2019, and October 2019.

(A copy of the letter from CDPHE to Prospect Energy is attached.)

Only 2 months after CDPHE’s warning letter to Prospect, Earthworks
documented the January 2021 violation. Then came more documented
violations – in March and again earlier this month.

A few weeks ago, Earthworks also documented illegal emissions from
another Prospect facility in the Hearthfire neighborhood

Unfortunately these emissions happen at O&G sites all the time. This is
oil & gas business as usual, how the industry has operated for decades.

Colorado law is clear: protection of public health holds priority in oil
& gas development. Larimer County’s oil & gas regulations uphold this law.

It is time to protect public health and the environment from these
harmful and illegal emissions.

It is also time to hold Prospect Energy fully accountable for its record
as a repeat violator.

Thank you for your attention to this.

Doug Henderson

Doug, along with our colleagues in Earthworks, has also been maintaining communication with Cassie Archuleta, Air Quality Program Manager for the City of Fort Collins, bringing attention to these sites Northeast of Fort Collins. Particular attention has been paid to one located near the Hearthfire neighborhood.

the BOULDERAIR tour rocked!

Thanks to efforts by Councilwomen Laurie Anderson of Broomfield, and to Andrew Forkes-Gudmunson of LOGIC, an idea for a tour became a reality last week. On short notice, a select crowd of community leaders, including some of from the Larimer Alliance, were asked if they would like to attend a tour of one of BoulderAIR‘s monitoring stations. Would a few of us be interested in attending the tour, at noon on Thursday, September 23, 2021?

You betcha! was the response. The organizers were trying to limit it to about a half dozen, but nearly twice that number showed up. People were from Broomfield, Fort Collins, and Loveland, including past Colorado legislator Mike Foote, who helped craft the historic SB-181 legislation.

The monitoring station from a distance

When we arrived at the Soaring Eagle Park in Broomfield, Dr Helmig, the CEO of BoulderAIR, was just finishing up a tour provided to members of the Aurora city government; so it was a busy tour day!

The previous tour group almost done

The Soaring Eagle Park in Broomfield is located in the Anthem housing development, which does have expansive views:

Looking north, where Longs Peak is visible in the distance

Unfortunately, this upscale housing development is also home to fracked wells, some just a few hundred feet from homes, which were drilled in the years prior to SB-181. Hence the strong interest by local government in getting such monitoring stations installed.

A stable tower anchors the mobile trailer that houses all the equipment, and provides the means of attaching the various sensors that record environmental conditions and air pollution:

Dr. Helmig explaining the various sensors

The trailer contains sophisticated equipment, worth tens of thousands of dollars, and analyzes the air samples in real time, and automatically publishing the data on the BoulderAIR website in less than 15 minutes. The equipment is under constant maintenance and calibration; though largely automated, the entire system nonetheless needs a good deal of tender loving care to keep it in good operating condition.

The big silver tubes connect to an air conditioner, which prevents the trailer from getting too hot inside

The presentation wrapped up with an explanation of the key piece of equipment: a gas chromatograph. The heart of the machine is this delicate part:

The orange coil is the heart of a gas chromatograph: a 50 meter long glass tube, barely a couple of millimeters wide, through which the gas sample travels

On the same site is another sampling station, an AJAX system, which is not part of BoulderAIR, but which Broomfield contracted to build prior to contracting with BoulderAIR:

The Soaring Eagle BoulderAIR station has the most complete set of sensors of any of the seven stations that they operate. It went into operation in April 2020, and has helped Broomfield identify several local pollutants, even ones not associated with oil and gas. There are two new fracked wells that went in within the past two years within about a mile radius; a third well’s drilling rig was just visible about a mile to the southeast from this site, which is being drilled now. So the city has ample reason for wanting a monitoring station in this area.

One of the many interesting facts that Dr. Helmig mentioned during the tour was that this station measured 40 days of non-compliance for ozone this past summer; the recommended threshold for maintaining human health set by the EPA is FOUR DAYS — in other words, this location in Broomfield was 10 TIMES THE RECOMMENDED SAFE THRESHOLD FOR SURFACE OZONE THIS SUMMER! It would be interesting indeed to study the data from those days and find out what percentage of the VOCs causing the ozone were from oil and gas sources versus VOCs coming from vehicular pollution. Why hasn’t this been done, one might wonder?

Well, apparently the state of Colorado is not interested in pursuing that question; and Broomfield does not have the expertise in-house to answer it either. But if BoulderAIR had the resources to hire more qualified staff, they could answer the question for us. But, as Dr. Helmig joked, you can’t just put out a Craigslist ad for this kind of job! Up until now, he has been so busy keeping the monitors going, his small team has not been able to pursue such questions; that might change in the future if BoulderAIR could hire more staff.

As far as anyone knows, these monitoring stations are unique: there are simply no other monitoring stations in the US, or in the world for that matter, that can match their analytical capability. Given the extreme amounts of ozone and, on occasion when accidents happen at oil and gas sites, dangerous amounts of other toxic chemicals that go wafting over the landscape, it would seem a no-brainer that more of these stations need to get built, AND more powerful regulations put in place to allow the state and local governments to shut down chronic pollution sources.

The Larimer Alliance is engaging with the city and county departments to support the installation of one or more such monitoring stations in the county, and support the important work of BoulderAIR. We will keep you posted of developments!
