Porter Ranch Residents Flee, Schools Close as Natural Gas Storage Facility Continues to Spew Toxic Chemicals

What type of medical monitoring is needed to assess the health impacts during this event and after residents are able to return to their homes?

There is currently very little data on health effects of the odorant chemicals beyond the physiological response to the odor. These compounds are utilized because they provide an effective warning about even small amounts of leaked gas. People are not expected to be subjected to them for very long and we need to understand better what the impact might be when exposures occur for a longer period of time.

How can warnings be improved to better capture the most vulnerable?

There is a great deal of scientific evidence showing that children, people with respiratory and cardiovascular diseases, and pregnant women are especially susceptible to many different types of air pollution. We need to make sure that all health-related advisories properly address these vulnerabilities and make sure these populations have the resources needed to protect themselves.

Unfortunately, the community of Porter Ranch is not alone in facing the impacts of oil and gas. On a daily basis, communities across California live with oil and gas infrastructure—from the well site to facilities which store, transmit, and distribute these resources to our homes and vehicles. The types of air pollutants and health threats can vary depending on the stage in the process and communities face different risks. This incident raises bigger questions about—and highlights huge gaps in—policies to evaluate and prevent community impacts from oil and gas in California.

• Our previous analysis found that about 5.4 million Californians live within one mile of an oil and gas well. Data to adequately characterize air emissions and levels of exposures in these communities is almost non-existent—although studies from other states show contaminants at levels that could put neighbors at risk. Communities living next door to these facilities regularly experience odors and health complaints consistent with air pollution yet, we have no monitoring data on the air they are breathing day in and day out.

• Current policies and regulations are way out of step with the science documenting air pollution threats from oil and gas sites. Strong federal and state standards are needed to limit emissions from these facilities, particularly at the well site. California air pollution control agencies need to start filling the gaps and prevent harmful air pollution from oil and gas.

• Despite numerous health and safety threats at oil and gas facilities, California lacks statewide protections to ensure that homes and schools are not in harm’s way.Health-protective setback distances are needed to keep communities safe.

• California has long history of oil and gas development. What was state-of-the art when it was drilled more than 50 years ago might not meet today’s standards. Plus, California is littered with old wells that have been abandoned or left idle without proper procedures to effectively seal them off. We need comprehensive policies, including reform of the Underground Injection Control (UIC) program, which ensure the integrity of the infrastructure and detect leaks from the diverse sources of equipment and facilities.

• Communities across the state are now asking themselves if they too might be at risk from an incident like what is unfolding in Porter Ranch. Comprehensive response plans that engage community members are need to review the locations of oil and gas infrastructure in their backyards and identify measures to prevent and respond to failures, both big and small.

It shouldn’t take a disaster to make us take a hard look at the safety of our oil and gas infrastructure. As the Porter Ranch community struggles to deal with the effects of this leak, we need to make sure they have the resources they need and California, as a whole, starts paying a lot more attention to the people whose lives are impacted daily by oil and gas facilities.
