Snow and Ice
Winter conditions can create specific environmental problems, indoors and out. When power lines are down, people run generators which can release toxic air pollutants inside homes and buildings. Deicing chemicals can damage local ecosystems and contaminate drinking water supplies. This page provides information about how to reduce these effects.

Around Your Home
People get sick or die each year from carbon monoxide or "CO" poisoning. Learn how to protect yourself and your family:
- Generator exhaust is toxic. Always put generators outside well away from doors, windows, and vents. Carbon
monoxide (CO) is deadly, can build up quickly,
and linger for hours.
More information about CO | Safe use of generators from FEMA - Proteja su vida y la de su familia: Evite el envenenamiento con monóxido de carbono (español) - conozca los síntomas del envenenamiento con monóxido de carbono. | Más: Tormentas de nieve y hielo
- Never operate a gas-burning appliance in a poorly vented or closed room, or where you are sleeping. Never try to heat your home using a "combustion appliances" like a gas stove, oven, barbeque grill, or dryer. More about combustion appliance safety, from CPSC.

Clearing ice? Find options that are less harmful than salt.
For municipalities and airports
- Manual for Deicing Chemicals: Application Practices - the results of a study about minimizing the loss to the environment of chemicals used in controlling snow and ice on highways.
- Road Salt Application and Storage - Application and storage of deicing materials, most commonly salts such as sodium chloride, can lead to water quality problems for surrounding areas. Municipalities in areas with snowfall that requires deicing must ensure proper storage for materials such as road salts.
- Storm Water Management Fact Sheet Minimizing Effects from Highway Deicing (PDF, 229 KB, 8 pp.) - This fact sheet emphasizes methods and practices for snow removal that are feasible and cost effective for local governments to implement and that are also consistent with sound environmental quality goals.
Road salt should be covered so it isn't
lost in stormwater runoff or doesn't clump together. More about road salt application and storage.
- Storm Water Technology Fact Sheet: Airplane Deicing Fluid Recovery Systems (PDF, 121 KB, 6 pp.) - The recovery of spent ethylene glycol or propylene glycol from industrial processes is accomplished by a three-stage process typically consisting of primary filtration, contaminant removal via ion exchange or nanofiltration, and distillation.
- Airport deicing effluent guidelines - Airports are required to obtain stormwater discharge permits and ensure that wastes from deicing operations are properly collected and treated. EPA is proposing effluent guidelines for the Airport Deicing Category.
