Riverstone South EAW January 2021 with project development. Project development is expected to result in routine effects on visual resources. The main visual effect will be the transition of views of the project area from mostly open agricultural land to residential development. The project will not involve installation of intense lights that would cause glare, nor will it include industries that would emit vapor plumes. 16. Air a. Stationary source emissions. Describe the type, sources, quantities and compositions of any emissions from stationary sources such as boilers or exhaust stacks. Include any hazardous air pollutants, criteria pollutants, and any greenhouse gases. Discuss effects to air quality including any sensitive receptors, human health or applicable regulatory criteria. Include a discussion of any methods used assess the project's effect on air quality and the results of that assessment. Identify pollution control equipment and other measures that will be taken to avoid, minimize, or mitigate adverse effects from stationary source emissions. The proposed project does not include heavy industrial facilities, but the project will still involve some stationary source air emissions. New residences and commercial buildings are expected to include heating and cooling systems operated by natural gas and electricity, which will result in direct or indirect sources of stationary greenhouse gas (GHG) emissions. Emissions from heating and cooling systems are expected to be similar to those from other homes in the surrounding area. The Minnesota Environmental Quality Board is working on a framework for integrating greenhouse gas (GHG) quantification and assessment requirements into the Environmental Review Program. However, standard requirements and assessment methods are not yet complete. In light of this constraint and in the absence of official guidance, the GHG assessment presented here is qualitative. Common GHG greenhouse gas emissions include CO2, CH4, N2O. GHG emissions are customarily converted to carbon dioxide equivalents (CO2e) using global warming conversion factors to represent the global warming potential over 100 years, equivalent to one ton of CO2 derived from fossil fuel. GHG emissions are expected to result from: 1. Operation of petroleum fueled equipment during project construction; 2. Use of natural gas and other fossil fuels used for heating homes; 3. Fossil fuels burned to generate electricity used at the project during construction and operation; 4. Vehicle and air transportation related to project construction and operation; 5. Transport, treatment, and storage of solid waste and wastewater produced onsite; 6. Loss of carbon sequestration due to conversion of natural vegetation to developed and paved surfaces; and 7. Refrigeration, air conditioning, and the related manufacturing, service, and leakage of equipment. 26
