Philadelphia's Anti-Pollution Efforts: Success Or Failure?

Philadelphia has a long history of pollution, which has shaped the city's history and geography. In recent years, the city has made efforts to improve its air quality and reduce congestion, receiving $7.3 million in federal funding for five projects aimed at improving air quality and reducing traffic congestion. The city has also updated its regulations on toxic air pollution from industrial facilities, expanding the list of regulated compounds and lowering emission thresholds. Despite these efforts, Philadelphia continues to face challenges with air pollution, particularly during the summer months when air quality worsens due to increased vehicle emissions and sunlight-driven chemical reactions. The city's air pollution is primarily driven by mobile emission sources, such as vehicles, rather than stationary sources like power plants.

The city received $7.3 million in funding to improve air quality and reduce congestion

The City of Philadelphia has taken several steps to improve air quality and reduce congestion. In 2016, the city received $7.3 million in competitive federal funding to implement five projects aimed at enhancing air quality and mitigating traffic congestion. This funding was awarded through the federal Competitive Congestion Mitigation and Air Quality (CMAQ) program, distributed by the Delaware Valley Regional Planning Commission (DVRPC).

The $7.3 million funded the following projects:

• Navy Yard Contra Flow Loop Shuttle: The Philadelphia Industrial Development Corporation (PIDC) received funding to increase the frequency of shuttle services between the Navy Yard and the AT&T Station on the Broad Street line. This improvement aimed to provide more viable and convenient commuting options for the more than 12,000 employees at the Navy Yard.
• Advancing CNGs in Philadelphia: This initiative involved purchasing new waste haulers that run on Compressed Natural Gas (CNG), reducing engine-related methane emissions. The grant also leveraged additional investment from the City of Philadelphia for more CNG waste haulers and the construction of a CNG fueling station.
• Ramping up to Rapid Transit on Roosevelt Boulevard: The project constructed 10 new bus stations at five intersections on Roosevelt Boulevard to support a new bus service planned by SEPTA. This initiative aimed to attract new transit riders, reducing vehicle miles travelled and emissions.
• Reformatting N. 5th Street: CMAQ funding was allocated to improve a segment of North 5th Street in the Hunting Park neighbourhood of North Philadelphia. The funding supported signal upgrades, fibre optic interconnection, bump-outs, sidewalk improvements, pavement markings, and street lighting upgrades.
• Fox Chase Lorimer Trail: This grant funded the development of a half-mile multi-use trail connecting the Fox Chase Regional Rail station at Rhawn Street to over 16 miles of existing trails along Pennypack Creek in Philadelphia and Montgomery Counties. The trail serves nearby residents, regional rail commuters, and the Fox Chase business district, offering a new connection to the regional trail system.

These projects demonstrate Philadelphia's commitment to improving air quality and reducing congestion through strategic investments in transportation infrastructure and the adoption of cleaner technologies.

The city has updated how it regulates toxic air pollution from industrial facilities

Philadelphia has a long history of pollution, dating back to its founding in 1682. Despite founder William Penn's intentions to create a spacious and orderly grid, the city soon faced issues with garbage disposal, unpaved roads, and industrial waste. Over the centuries, Philadelphia has struggled with various forms of pollution, including air, land, and water contamination, which have had significant environmental and public health impacts.

In recent years, the city has taken steps to address these issues and reduce pollution. Notably, in 2023, Philadelphia updated how it regulates toxic air pollution from industrial facilities for the first time in over four decades. The Air Pollution Control Board approved a revision to an obscure regulation that covers compounds like asbestos, lead, arsenic, and cancer-causing benzene. This revision expands the list of regulated toxic air pollutants and lowers the emissions thresholds that trigger health risk assessments.

While some critics argue that the revision doesn't go far enough, others applaud it as a major step forward in reducing potential carcinogens in the region's air. The updated regulation will come into effect at the beginning of 2024 and will impact both new and existing facilities that emit toxic air pollutants above certain thresholds.

The city's efforts to reduce toxic air pollution from industrial facilities are part of a broader push to improve air quality and reduce congestion. In 2016, Philadelphia received $7.3 million in competitive federal funding for five projects aimed at improving air quality and reducing traffic congestion. These projects included cleaner waste haulers, transit improvements, and the development of new trails.

Philadelphia's history with pollution is complex, and the city continues to grapple with the challenges of reducing air, land, and water contamination. The updated regulation on toxic air pollution from industrial facilities is a significant step forward, demonstrating the city's commitment to creating a cleaner and healthier environment for its residents.

Air pollution is worse in the summer

Philadelphia has a long history of pollution, which has shaped the city's history and geography. The city has made efforts to reduce pollution and improve air quality, but it continues to face challenges.

Now, onto why air pollution is worse in the summer.

Air pollution is influenced by weather conditions such as wind and air pressure, temperature, sunlight, and humidity. Summer weather conditions can lead to higher levels of air pollution and negatively impact air quality. Here are some reasons why:

Increased Sunlight and Temperature

The combination of sunlight and high temperatures during summer creates the perfect conditions for the production of ground-level ozone, a harmful secondary pollutant. Ground-level ozone is formed through chemical reactions involving nitrous oxides and volatile organic compounds, and it poses various health risks, including difficulty breathing, aggravation of lung diseases, increased frequency of asthma attacks, and potentially increased risk of premature death due to heart or lung disease.

Stagnation Events

Hot and dry summer weather can lead to stagnation events, where the air becomes stagnant and pollutants build up in the air we breathe. This stagnation is made worse by heatwaves, which are becoming more frequent and intense due to climate change. The increasing summer temperatures result in more stagnant days, posing a threat to air quality and human health.

Wildfires

Summer is also associated with drought conditions, which increase the risk of wildfires. Wildfires significantly degrade air quality by adding carbon monoxide and particulate matter to the atmosphere, posing threats to both human and environmental health.

Human Behavior

Seasonal patterns in human behavior can also contribute to higher air pollution during the summer. For example, people tend to spend more time outdoors during the summer, engaging in activities that can increase air pollution, such as barbecuing or using lawn equipment. Additionally, increased use of air conditioning during hot summer months can contribute to higher energy consumption and associated emissions.

While some types of pollution are worse during the summer, it's important to note that air pollution is a complex issue that varies with geographical location and other factors. Different regions may experience different pollution patterns, and local factors such as industry, transportation, and population density can also play a significant role in air quality.

Air pollution is highest in Center City

Air Pollution in Philadelphia

Philadelphia, the largest city in the US state of Pennsylvania, has a long history of pollution, dating back to its early days as an industrial hub. While the city has made efforts to improve air quality, it continues to face challenges, particularly in Center City. This article will explore the factors contributing to high air pollution levels in Center City Philadelphia and the potential health risks for its residents.

Sources of Air Pollution in Center City

Center City Philadelphia, the economic and cultural heart of the region, is plagued by various sources of air pollution. One of the primary contributors is mobile emission sources, including motor vehicles, airplanes, and locomotives. The high density of traffic in Center City, coupled with the large number of vehicles, leads to significant emissions of pollutants such as nitrogen dioxide, particulate matter, and ground-level ozone. These pollutants have detrimental effects on respiratory health and can aggravate existing conditions such as asthma.

In addition to mobile sources, stationary sources also play a role. Power plants, oil refineries, and factories located in and around Center City release pollutants into the atmosphere. One notable example is the Philadelphia Energy Solutions refining complex, which was once the city's largest stationary emission source. While this complex was shut down in 2019 due to a catastrophic fire, its emissions have likely contributed to the area's poor air quality for many years.

Health Risks Associated with Air Pollution in Center City

The consequences of air pollution in Center City Philadelphia are far-reaching, impacting the health and well-being of its residents. Sensitive groups, including children, the elderly, and individuals with pre-existing heart or lung diseases, are particularly vulnerable. Prolonged exposure to air pollutants can lead to a range of health issues, including respiratory problems, coughing, throat irritation, and even the development of chronic respiratory diseases.

Fine particulate matter, with a diameter of less than 2.5 micrometers, poses a severe threat as it can be inhaled and enter the lungs and bloodstream. This can result in serious health complications, especially for the lungs and heart. Ground-level ozone, formed from precursor pollutants reacting in sunlight, is another significant concern, as it can aggravate respiratory diseases and cause throat irritation, headaches, and chest pain.

Center City Philadelphia faces high levels of air pollution due to a combination of mobile and stationary emission sources. The dense traffic and industrial activities in the area contribute to an unhealthy air quality that poses risks to human health. While there have been some efforts to mitigate pollution, more comprehensive measures are needed to protect the residents of Center City from the detrimental effects of air pollution.

The city has a high rate of asthma, likely caused by air pollution

Philadelphia has a long history of pollution, dating back to its founding in 1682. Despite founder William Penn's intentions to create a spacious and orderly grid, the city has struggled with pollution and its health impacts over the centuries.
