An interactive map sheds light on which California communities are disproportionately burdened by pollution

CalEnviroScreen was built by the Office of Environmental Health Hazard Assessment (OEHHA), part of the California Environmental Protection Agency. In it, pollution and population data combine to shed light on which communities bear the brunt of environmental and health hazards. Addressing this inequality is known as environmental justice.
“It is both a map and a way to think about the power of maps, in this case facilitating a geographic approach to realize the goals of environmental justice,” explained Stephen Gay, Equity & Social Justice blogger for Esri.
Using modern geographic information system (GIS) technology, CalEnviroScreen ranks and color codes California’s more than 8,000 census tracts to reflect vulnerability to pollution. The formula behind CalEnviroScreen considers the presence of various types of pollution, the prevalence of health problems that can be worsened by pollution, and population data.
The main map shown here illustrates the combined Pollution Burden scores, made up of indicators from the Exposures and Environmental Effects components of the CalEnviroScreen model. In addition to an overall score, CalEnviroScreen provides map-building tools to isolate 21 specific datasets.
Communities with a heavy pollution burden often experience high poverty that makes them more vulnerable to pollution’s effects. Pollution data includes cleanup sites, water quality (such as groundwater contamination, lead exposure, pesticide runoff) and air quality (including traffic exhaust, ozone, particulate matter). Deleterious health effects include asthma, heart disease, low birth weight and more.
The map itself is only the most visible manifestation of CalEnviroScreen, which CalEPA said is a screening methodology “to help identify California communities that are disproportionately burdened by multiple sources of pollution.”
ITU is the United Nations agency that deals with information and communications technology. Its remit includes coordinating spectrum use and satellite orbits.
ITU’s Radio Communications Bureau sponsors the World Radiocommunication Conference every three to four years. The issue of interference with GNSS signals was reported at the 2019 conference.
Since that time, according to this month’s circular, the group “has been informed of a significant number of cases of harmful interference to the radionavigation-satellite service…”
Despite concerns expressed by maritime and other interests, the circular focuses entirely on aviation interference. It says the reports it has received have been about “receivers onboard aircrafts and causing degradation or total loss of the service for passenger, cargo and humanitarian flights…” These have included “misleading information provided by RNSS [radionavigation satellite service] receivers to pilots.” An often cited example of this is a well-publicized 2019 incident in Sun Valley, Idaho. In that case a passenger aircraft nearly hit a mountain.
Describing interference with GNSS as a global and recurrent problem, the circular cites data collected by a major aircraft manufacturer. The company found “10,843 radio-frequency interference events … globally in 2021. The majority of these events occurred in the Middle East region, but several events were also detected in the European, North American and Asian regions.”
This year’s uptick in GNSS interference in Scandinavia, the Baltics, and around Ukraine since Russia’s February invasion of Ukraine is not mentioned. This is likely due, in part, to timing. ITU’s Radio Regulations Board met in March 2022 and directed the circular be issued.
Many within the positioning, navigation, and timing community have long asserted that interference with GNSS signals, whether deliberate or accidental, constitutes a violation of ITU rules and regulations. This month’s circular affirms this and cites several applicable provisions.
These include prohibitions on harmful interference with any authorized radio frequency transmission, requirements for users to transmit only in bands for which they have authorization, and for all to generally safeguard aviation operations.
The circular highlights provision 15.1 of ITU’s Radio Regulations as particularly applicable. It states:
“All stations are forbidden to carry out unnecessary transmissions, or the transmission of superfluous signals, or the transmission of false or misleading signals, or the transmission of signals without identification…”
As is the case with almost all international agreements, enforcement of ITU rules is the responsibility of its member states.
While most expect the advisory to have little immediate impact on reducing global interference with GNSS signals, it does help reinforce the issue as one of international concern.
According to a retired government official, “Member states that fail to comply with international rules to which they have agreed lose credibility and standing in the community of nations. Even when they have little credibility or standing to begin with, the behavior adds to their marginalization and life is just a little more difficult for them. This can, in the long run, nudge them toward being more responsible players.”

This month, we have developments across the globe, with drones inspecting power distribution systems and nuclear waste disposal in the United Kingdom, counter UAS (C-UAS ) systems deployed in Greece, and news of cutbacks in the UAV industry affecting two major suppliers.
UK Turns to Drone Power
The UK has reduced coal power generation significantly since 2013 by increasing use of natural gas, nuclear power and renewable sources. Power is distributed throughout the UK by the National Grid Electricity Transmission (NGET) via 4,000 miles of overhead high-voltage lines carried on 21,900 steel pylons. With another 330 substations to also look after, the infrastructure for power distribution in UK always has required a huge maintenance effort. This picture is likely reflected in the power distribution networks of most countries around the world.
Helicopters have carried a large portion of the workload to enable inspection of cables and insulators, with additional necessary manual inspections taking significant effort to gain access and analyze data. Helicopter time is expensive, and manual inspection processes and data analysis are tedious and time consuming.
Drones are being used for power-line inspection — flown manually by onsite operators — by many organizations in several countries around the world, including by FPL in Florida. But the real reduction in time and effort comes from automating the whole process, and gathering data that provides the detail necessary to assure defects are detected and operational integrity is maintained. The automation of data analysis and generation of useful reports is another area which could yield major savings, and bring rapid focus to areas needing immediate corrective action.

Hence, a 12-month trial is being undertaken involving ultimate approval by the UK Civil Aviation Authority (CAA) for beyond-visual-line-of-sight (BVLOS) multiple drone operations. Artificial intelligent (AI) analysis tools are being developed to determine critical changes in collected visual, lidar and positioning inspection data that might herald deterioration in pylon or other infrastructure components.
During an initial test in Nottingham, an autonomous drone was dispatched with minimal instructions. It was able to find its inspection target and complete the programmed inspection in a few minutes. A manual inspection could take up to an hour for the same task. If things go well, it is not impossible to be able to project multiple drones operating with minimal human control, taking on huge swaths of pylons, cabling, insulators and other elements during regular inspections, saving a lot of time and money.
The trials so far have also included remote inspection of the Sellafield nuclear waste decommissioning site, rail infrastructure and a telecommunications network along with investigations towards transport of medical supplies.
Sellafield is where spent fuel ends up from the UK’s 31 nuclear power plants. Also, nuclear waste from reactors in neighboring European countries is reprocessed here. Nuclear waste is processed into 50-ton concrete blocks and spent fuel is “vitrified” into huge chunks of glass, which are encased in an outside metal jacket. Both processes minimize any emitted radiation and allow the contents to safely cool over long term. The staff uses robots inside the facility to remotely dismantle contaminated areas and load material into 55-gallon drums, which might be further processed by robot crushing machines. No one has any real idea how all this nuclear waste could be permanently disposed of, but it’s possible most will ultimately be buried in the ground.
This type of power might seem a “green” boon for humanity, but in a somewhat countrified area on the West Coast of England and in other similar sites around the world, nuclear waste disposal is costly and very, very long-term. The half-life of uranium is between 159,200 years and 4.5 billion years. Monitoring the waste could be a long-term task for drones, such as those now used to detect radiation inside the Fukushima nuclear plant. Certainly, there’s plenty of time to evolve improved drone detection capability for radiation monitoring.
Greece Employs Counter-UAS against Turkish Incursions
On a defense-related note, apparently the long-running rivalry between Turkey and Greece is, unfortunately, continuing. It seems that Turkey has been repeatedly flying its Baykar-TB2 surveillance drone over Greek islands, perhaps to monitor the movements of Greek warships or island defense installations. And Greece is a little bit more than peeved.
Having established a defense-related relationship with Israel in 2021, Greece has brought Israeli drone defense systems to the Greek islands, installing a “veritable umbrella against enemy unmanned aerial vehicles.” The Israeli system has a number of moving parts: detect and identify; generate related alerts; a directional jamming system that can disable drones in flight (presumably by jamming GPS or the control link); and a laser that can lock onto a small target and, if manually fired, can apparently destroy an intruder drone.

Because of the directional, narrow beamwidth of the jammer, Rafael claims that the system can be activated within crowded civilian airspace without affecting the navigation of other users. Good news for Greece and their popular, attractive Greek island tourist destinations.
UAV Defense Contractors Struggle — with Each Other
Meanwhile, current economic uncertainty is apparently impacting at least a couple of UAV defense contractors: Boeing/Insitu and Orbital UAV. The two made news when Orbital, as an Australian public company (ASX symbol OEC), had to halt trading. The company was then able to reinstate trading largely because of news of cancellation of a development/production agreement with Insitu.
Apparently, Orbital has previously been delivering two-engine versions to Insitu and was contracted to develop and deliver a third derivative engine. However, Insitu had to scale back Orbital’s work in February, given its sales of the popular ScanEagle and other UAVs may have fallen off in recent months.

This has affected Orbital’s revenue forecast for the year. The company now expects to lose AUD $7 million for the year. It has subsequently prepared a claim under the supply agreement for Insitu’s Termination for Convenience of AUD $1.8 million in costs incurred in the development of the third engine program, which Insitu/Boeing disputes. There will obviously be some wrangling, but hopefully both parties will settle things amicably so as not to damage their ongoing relationship for supply of the existing two engine types.

To sum up, for this month we have a trial in the UK which will hopefully lead to significant savings in effort and costs for ongoing power infrastructure inspections, along with some background on UK nuclear waste disposal. Greece is bristling and defending against unwanted Turkish drone overflight using Israeli C-UAS systems. Finally, there’s somewhat negative news for the Orbital UAV engine and Insitu ScanEagle relationship — apparently, not everything in the UAV garden is roses.
