Stormwater Information

The City of Chicopee currently maintains combined sewers as well as separate sewer and stormwater systems. The Municipal Separate Storm Sewer System (MS4) is regulated by the EPA under permit #MA041003. Protecting the quality of Chicopee's water resources, including ponds, rivers, and wetlands, is a priority for the City. Chicopee has developed stormwater policy initiatives, provided education to businesses and citizens, publicly discussed the issues related to stormwater runoff, and offered opportunities for residents and businesses to pitch in with clean-up efforts.

In an ongoing effort to minimize stormwater impacts within Chicopee, the City has developed a Stormwater Management Plan (SWMP). The SWMP is required by the EPA's National Pollutant Discharge Elimination System (NPDES) general permits for stormwater discharges from MS4s in Massachusetts. The SWMP describes and details the activities and measures that will be implemented by the City to meet the terms and conditions of the permit.

The SWMP will be updated and/or modified during the permit term as the City's activities are modified, updated, or changed to meet permit conditions.

The Think Blue Connecticut River website was developed by the Connecticut River Stormwater Coalition, of which the City of Chicopee is a proud member and contributor. It has stormwater information and ideas for residents, businesses, institutions, developers, industries, and educators. 


GLOSSARY OF COMMON STORMWATER TERMS

Aquifer: An aquifer is an underground layer that contains groundwater.

Atmosphere: A unit of atmosphere measures the air pressure at sea level, which is about 14.7 pounds per square inch.

Climate: The climate of a location includes all of the weather conditions for this location over an extended period of time.

Cloud: A cloud is a visible mass of small water droplets or tiny ice crystals that are suspended in the atmosphere.

Cloud Condensation Nuclei: Water vapor surrounds tiny particles, condensing in clouds to become raindrops.

Condensation: Condensation is the process by which water vapor changes into liquid.

Current: Currents are predictable and steady flows of fluid in a larger body of fluid.

Density: Density describes the amount of things in a specific space.

Dew Point: Dew point is the temperature at which water in the air condenses to become water droplets near the ground.

Ecosystem: An ecosystem is a community of living and nonliving things in an area.

Erosion: Erosion happens when soil is worn away, usually by wind, water, or ice.

Evaporation: Evaporation is the process of water changing into water vapor.

Evapotranspiration: When moisture from the soil evaporates into the atmosphere or when transpiration from plants occurs, this is called evapotranspiration.

Fog: Clouds near the ground are known as fog.

Freshwater: A lake, river, or spring is a source of freshwater, which animals can drink.

Glacier: A glacier is a mass of ice that moves slowly across a land mass.

Great Lakes: The Great Lakes are the biggest freshwater bodies of water in the world, located in the United States.

Greenhouse Gas: Gases in the atmosphere that absorb solar heat reflected by Earth's surface, contributing to warming of the atmosphere, are greenhouse gases.

Groundwater: Groundwater is water found in an aquifer.

Humidity: The amount of water vapor in the air is the humidity.

Ice: Ice is water in solid form.

Ice Cap: An ice cap is an area of less than 19,000 square miles covered by ice.

Ice Sheet: Ice sheets are glacial ice areas that cover a large expanse.

Lake: A lake is a body of water that is surrounded by land.

Microscopic: Microscopic describes something very small.

Pollutant: A pollutant is a substance that harms a natural resource.

Precipitation: Precipitation includes all types of water that fall to Earth.

River: A river is a big stream of fresh water that flows.

Runoff: When fluid overflows from a farm or factory, it's known as runoff.

Snowmelt: Melted water from snow is snowmelt.

Temperature: The level of heat or cold, measured by a thermometer, is temperature.

Transpiration: Water that evaporates from plants is transpiration.

Vapor: Vapor is liquid that is suspended in air.

Water Cycle: Water moves between the land, bodies of water, and atmosphere in a process known as the water cycle.

Weather: Weather describes the state of the atmosphere, and it includes atmospheric pressure, temperature, humidity, cloudiness, precipitation, and wind.

Wind: Wind is air that moves from areas of high pressure to low-pressure zones.
