The Michigan Department of Environment, Great Lakes, and Energy's (EGLE) Environmental Remediation Program manages and reduces risk at sites of environmental contamination. This is achieved through activities such as site evaluation, feasibility studies, operation and maintenance of systems, implementing land use and resource use restrictions, and monitoring. This data layer shows facilities that have been identified and mapped under Part 201, Environmental Remediation, of the Natural Resources and Environmental Protection Act, 1994 PA 451, as amended (NREPA) those areas, places, or parcels of property, or portion of a parcel of property where a hazardous substance in excess of the concentrations that satisfy the cleanup criteria for unrestricted residential use has been released, deposited, disposed of, or otherwise comes to be located. This data layer does not include all of the facilities that are subject to regulation under Part 201 because owners are not required to inform EGLE about the facilities and can pursue cleanup independently. Facilities that are not known to EGLE are not on the Inventory, nor are locations with releases that resulted in low environmental impact. This data is regularly updated.

Many businesses utilize underground storage tanks for products such as gasoline, diesel fuel, and other liquid chemicals. Environmental damages and safety risks can result from improper installation and maintenance as well as degradation of the tanks over time. The design, construction, installation and maintenance of underground storage tanks that store regulated substances are licensed under Part 211, Underground Storage Tank Regulations, of the Natural Resources and Environmental Protection Act, 1994 PA 451, as amended (NREPA) by the Michigan Department of Licensing and Regulatory Affairs (LARA). Those underground storage tanks that require corrective actions due to a release are regulated under Part 213, Leaking Underground Storage Tanks, of NREPA by the Michigan Department of Environment, Great Lakes, and Energy (EGLE). This data layer shows the locations of known underground storage tanks in Michigan including those that have a record of a release. This data is regularly updated.

If you have questions related to air quality, please reach out to Susan Kilmer (KilmerS@Michigan.gov or 517-242-2655). If you have map suggestions or functionality issues, please reach out to EGLE-Maps@Michigan.gov.From US EPA AirNow:Although preliminary data quality assessments are performed, the data in AirNow are not fully verified and validated through the quality assurance procedures monitoring organizations used to officially submit and certify data on the EPA Air Quality System (AQS).This data sharing, and centralization creates a one-stop source for real-time and forecast air quality data. The benefits include quality control, national reporting consistency, access to automated mapping methods, and data distribution to the public and other data systems. The U.S. Environmental Protection Agency, National Oceanic and Atmospheric Administration, National Park Service, tribal, state, and local agencies developed the AirNow system to provide the public with easy access to national air quality information. State and local agencies report the Air Quality Index (AQI) for cities across the US and parts of Canada and Mexico. AirNow data are used only to report the AQI, not to formulate or support regulation, guidance or any other EPA decision or position.About the AQIThe Air Quality Index (AQI) is an index for reporting daily air quality. It tells you how clean or polluted your air is, and what associated health effects might be a concern for you. The AQI focuses on health effects you may experience within a few hours or days after breathing polluted air. EPA calculates the AQI for five major air pollutants regulated by the Clean Air Act: ground-level ozone, particle pollution (also known as particulate matter), carbon monoxide, sulfur dioxide, and nitrogen dioxide. For each of these pollutants, EPA has established national air quality standards to protect public health. Ground-level ozone and airborne particles (often referred to as "particulate matter") are the two pollutants that pose the greatest threat to human health in this country.A number of factors influence ozone formation, including emissions from cars, trucks, buses, power plants, and industries, along with weather conditions. Weather is especially favorable for ozone formation when it’s hot, dry and sunny, and winds are calm and light. Federal and state regulations, including regulations for power plants, vehicles and fuels, are helping reduce ozone pollution nationwide.Fine particle pollution (or "particulate matter") can be emitted directly from cars, trucks, buses, power plants and industries, along with wildfires and woodstoves. But it also forms from chemical reactions of other pollutants in the air. Particle pollution can be high at different times of year, depending on where you live. In some areas, for example, colder winters can lead to increased particle pollution emissions from woodstove use, and stagnant weather conditions with calm and light winds can trap PM2.5 pollution near emission sources. Federal and state rules are helping reduce fine particle pollution, including clean diesel rules for vehicles and fuels, and rules to reduce pollution from power plants, industries, locomotives, and marine vessels, among others.How Does the AQI Work?Think of the AQI as a yardstick that runs from 0 to 500. The higher the AQI value, the greater the level of air pollution and the greater the health concern. For example, an AQI value of 50 represents good air quality with little potential to affect public health, while an AQI value over 300 represents hazardous air quality.An AQI value of 100 generally corresponds to the national air quality standard for the pollutant, which is the level EPA has set to protect public health. AQI values below 100 are generally thought of as satisfactory. When AQI values are above 100, air quality is considered to be unhealthy-at first for certain sensitive groups of people, then for everyone as AQI values get higher.Understanding the AQIThe purpose of the AQI is to help you understand what local air quality means to your health. To make it easier to understand, the AQI is divided into six categories:Air Quality Index(AQI) ValuesLevels of Health ConcernColorsWhen the AQI is in this range:..air quality conditions are:...as symbolized by this color:0 to 50GoodGreen51 to 100ModerateYellow101 to 150Unhealthy for Sensitive GroupsOrange151 to 200UnhealthyRed201 to 300Very UnhealthyPurple301 to 500HazardousMaroonNote: Values above 500 are considered Beyond the AQI. Follow recommendations for the Hazardous category. Additional information on reducing exposure to extremely high levels of particle pollution is available here.Each category corresponds to a different level of health concern. The six levels of health concern and what they mean are:"Good" AQI is 0 to 50. Air quality is considered satisfactory, and air pollution poses little or no risk."Moderate" AQI is 51 to 100. Air quality is acceptable; however, for some pollutants there may be a moderate health concern for a very small number of people. For example, people who are unusually sensitive to ozone may experience respiratory symptoms."Unhealthy for Sensitive Groups" AQI is 101 to 150. Although general public is not likely to be affected at this AQI range, people with lung disease, older adults and children are at a greater risk from exposure to ozone, whereas persons with heart and lung disease, older adults and children are at greater risk from the presence of particles in the air."Unhealthy" AQI is 151 to 200. Everyone may begin to experience some adverse health effects, and members of the sensitive groups may experience more serious effects."Very Unhealthy" AQI is 201 to 300. This would trigger a health alert signifying that everyone may experience more serious health effects."Hazardous" AQI greater than 300. This would trigger a health warnings of emergency conditions. The entire population is more likely to be affected.AQI colorsEPA has assigned a specific color to each AQI category to make it easier for people to understand quickly whether air pollution is reaching unhealthy levels in their communities. For example, the color orange means that conditions are "unhealthy for sensitive groups," while red means that conditions may be "unhealthy for everyone," and so on.Air Quality Index Levels of Health ConcernNumericalValueMeaningGood0 to 50Air quality is considered satisfactory, and air pollution poses little or no risk.Moderate51 to 100Air quality is acceptable; however, for some pollutants there may be a moderate health concern for a very small number of people who are unusually sensitive to air pollution.Unhealthy for Sensitive Groups101 to 150Members of sensitive groups may experience health effects.

Dams in Michigan are regulated by Part 307, Inland Lake Levels, and Part 315, Dam Safety, of The Natural Resources and Environmental Protection Act, 1994 PA 451, as amended. There are 2,500+ dams in the state, most of which are regulated by Part 315. Dams are regulated by Part 315 when they are over 6 feet in height and over 5 acres are impounded during the design flood. Dams are regulated by Part 307 when a circuit court issues an order establishing the level at which the lake is to be maintained. There are also 99 hydroelectric dams in Michigan that are regulated by the Federal Energy Regulatory Commission (FERC) under the Federal Power Act. The Dam Safety Program is responsible for ensuring the safety of Michigan's state regulated dams. These dams, owned by both public and private entities, are located throughout the state. The program focuses on ensuring that dams are properly constructed, inspected and maintained, and that the owners have adequately prepared for potential emergencies.

This data set provides an estimate of annual groundwater recharge for each public land survey section in Michigan. Groundwater Inventory and Mapping Project, a cooperative effort between the Water Bureau - Michigan Department of Environmental Quality (now Michigan Department of Environment, Great Lakes, and Energy), USGS - Michigan Water Science Center and Michigan State University - Institute of Water Research, RS&GIS and Biosystems and Agricultural Engineering. This project was mandated by P.A. 148 (Michigan Acts of 2003). Major funding was provided by EGLE (MDEQ at the time), supplemented with additional funds from the USGS Cooperative Water Program.Public Law 148 required the MDEQ to obtain a map of state-wide groundwater recharge. The US Geological Survey and Michigan State University have created this data set to meet that need.Accuracy of the recharge estimate is estimated to be +/- 2.44 inches/yr in the western and northern Lower Peninsula, +/- 1.1 in/yr in the southeastern Lower Peninsula, and +/- 2.9 inches/yr in the Upper Peninsula. Areas in the eastern Upper Peninsula (Luce, Chippewa, and Mackinaw Counties) may have higher error because of relatively poor representation of specific geologic environments.Base flow separations were compiled 208 USGS streamflow gages in Michigan from those completed by Neff and others (2005). Within each region, an average recharge rate was calculated based on the baseflow yield. Residuals were computed for each streamflow gage.Watershed characteristics describing the geology, land cover, and general climate characteristics of the gaged watersheds were also compiled. These data were analyzed in Systat v.11 using a forward stepwise regression procedure to identify watershed characteristics that might be useful in predicting the value fo the residual. Within the eastern Lower Peninsula, the significant predictive variables, in addition to area, were: agricultural land use, urban land use, annual growing degree days, annual precipitation, and percent of the watershed underlain by lacustrine deposits. Within the western Lower Peninsula, the significant predictive variables, in addition to area, were: winter (December through March) precipitation, the percentage of the watershed underlain by till, and the percentage of the watershed occupied by forests. In the Upper Peninsula, the significant predictive variables, in addition to area, were: growing degree days and winter precipitation.Each of these predictive variables were calculated for each Public Land Survey section, the data used to predict a residual, then the residual added to the base recharge prediction for the region.
