Granite Bridge will help reduce air emissions and increase public health by providing New Hampshire homes and businesses a clean, efficient heating option. By using a state-designated energy infrastructure corridor, Granite Bridge will avoid impacts to New Hampshire's natural resources. Customers of Liberty Utilities can also access our award-winning energy efficiency programs, which reduce costs, save fuel and increase comfort.
Granite Bridge will enable over 24,000 homes and over 1,500 businesses to choose clean natural gas over the next 20 years. In addition to the reduction in emissions from burning a clean, efficient fuel, access to natural gas also reduces heavy truck traffic that is required to deliver other fuels.
Greenhouse Gas (CO2 equivalent)
= 200,023 cars off the road
Greenhouse gases lead to global climate change, which increases global temperature, creates more severe weather conditions, impacts food production and increases sea levels, among other impacts.
= 1,983,024 cars off the road
Particulate matter can cause negative health effects on the heart and lungs, such as respiratory disease and non-fatal heart attacks. Environmental effects include acid rain, depletion of nutrients in soil and water, and negative effects on the diversity of ecosystems.
= 170,999 cars off the road
Emissions of nitrogen oxides can lead to respiratory infection and disease, such as asthma. Environmental effects include acid rain, haze, and nutrient pollution in coastal waters.
Sulfur dioxide emissions can also impact health and the environment. Like nitrogen oxides, health impacts include respiratory infection and disease, such as asthma. Environmental effects include acid rain and haze.
Mercury emissions can cause a wide variety health and environmental impacts. Some of the health impacts include headaches, changes in nerve response, and poor performance on test of mental function. Prolonged high exposure can cause kidney effects, respiratory failure, and death. Environmental effects are concentrated in animals that eat fish. Due to mercury exposure, these animals are subject to reduced reproduction, slower growth and development, and abnormal behavior, and even death.
Emissions reductions compared to home heating oil, over the next 20 years. Equivalent to taking the stated number of average passenger vehicles off the road for one year.
With the exception of particulate matter and mercury, the emission reductions account for both emissions due to fuel combustion, as well as emissions from upstream processing (such as extracting, processing, and transportation).
Reducing emissions will decrease pollution-related illnesses in New Hampshire, including respiratory infections and diseases such as asthma.
Continued access to natural gas as a heating option would save between $1.8 million and $3.9 million in total health costs over the next 20 years in New Hampshire, by reducing pollution-related illnesses.
RESPECTING NATURAL RESOURCES
The entire pipeline route will be completely buried within New Hampshire Department of Transportation right-of-way along Route 101.
This section of highway is a state-designated energy infrastructure corridor, which the New Hampshire Legislature created to protect the New Hampshire’s natural resources, reduce impacts to private property and encourage orderly, planned energy development.
EXPANDING ENERGY EFFICIENCY
Total project savings
Building Granite Bridge will increase access to Liberty Utilities’ award winning NHSAVES energy efficiency programs, helping homes and businesses install efficient heating and hot water equipment, advanced controls, air sealing and insulation, and more.
The EPA has named Liberty Utilities’ energy efficiency programs “Energy Star Partner of the Year for Sustained Excellence” 5 years in a row.
The NHSAVES programs have already saved the equivalent of more than 24,000 homes worth of natural gas, and reduced carbon emissions by the equivalent of taking 41,000 cars off the road for a year.
